Embodiments of the present invention are generally directed to high capacity balers. More particularly, embodiments of the present invention are directed to an electronic display for a baler configured to present one or more parameters related to a plurality of bales being formed by the baler.
Balers are agricultural implements that form bales (e.g., square or round-shaped bales) of crop material. Most currently available square balers use a single baling chamber with a single gearbox, a single plunger, and a single knotter assembly to produce one square bale at a time. To increase baling efficiency, there is a desire to increase the capacity of some balers to produce more bales per hour. One way to increase baler capacity is to run the baler's plunger faster; however, due to concerns with knotter assembly reliability at high speeds, plunger speeds have maxed out at approximately one hundred revolutions per minute. Another option to increase baler capacity is to use thicker flakes when forming the bales; however, end users of bales often object to bale flakes being too large. Also, larger flakes can lead to inconsistent bale lengths.
These limitations have led to special hitches that pull two balers with one tow vehicle. While this solution can increase bale production, the use of two balers negatively impacts maneuverability of the tow vehicle and/or of the balers during both field operation and transport.
One embodiment of the present invention includes a baling system comprising a high capacity baler, and an electronic display configured to display baling information to an operator of the baling high capacity baler. The baler additionally comprises a first bale-forming area in which a first series of first individual bales can be formed, and a second bale-forming area in which a second series of second individual bales can be formed. The baler further comprises one or more first sensors configured to sense one or more parameters related to at least one of the first bales, and one or more second sensors configured to sense one or more parameters related to at least one of the second bales. The electronic display is configured to simultaneously display data generated from at least one of the first sensors and at least one of the second sensors.
In another embodiment of the present invention, there is provided a method of forming a plurality of bales of crop material with a high capacity square baler. The method comprises one step of the steps of forming a first series of first bales in a first bale-forming area. The method includes an additional step of forming a second series of second bales in a second bale-forming area. The method includes an additional step of obtaining, via one or more sensors, data related to the first and the second bales being formed within the first and the second bale-forming areas, respectively. The method includes a further step of presenting, via an electronic display, one or more parameters based on the data obtained via the one or more sensors.

This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Other aspects and advantages of the present invention will be apparent from the following detailed description of the embodiments and the accompanying drawing figures.

The drawing figures do not limit the present invention to the specific embodiments disclosed and described herein. The drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the invention.
The following detailed description of the present invention references various embodiments. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.
Broadly, embodiments of the present invention are directed to agricultural implements in the form of crop balers, such as baler 10 illustrated in
The baler 10 may include a wheeled chassis 12 including an axle 14 and a pair of laterally spaced wheels 16 that support the chassis 12 above the ground. The baler 10 may additionally comprise a plurality of baling chambers 18, extending generally in a fore-and-aft direction and which are supported on top of the chassis 12. As will be described in more detail below, the baling chambers 18 are configured as bale forming chambers or areas in which small, square bales of crop material can be formed. Because the baler 10 includes a plurality of baling chambers 18, the baler 10 may be referred to as a “high capacity” baler capable of simultaneously forming multiple bales of crop material. In some specific embodiments, the baler 10 will include two baling chambers 18 supported on the chassis 12 and positioned between the wheels 16. As will be described in more detail below, the plurality of baling chambers 18 permits the baler 10 to simultaneously form a plurality of bales of crop material. In some embodiments, the plurality of bales of crop material may be formed by the baler 10 picking up crop material from a single windrow of crop material.
In some embodiments, the baler 10 may be pulled or pushed by a towing vehicle (e.g., a tractor, which is not shown in the drawings). In alternative embodiments, the baler 10 may be self-propelled. For example, the baler 10 may include an internal combustion engine and any other components necessary for the baler 10 to operate independently of any other machine or towing vehicle. Returning to embodiments in which the baler 10 is pulled by a towing vehicle, the chassis 12 of the baler 10 may include a forwardly-extending tongue 20, as illustrated in
To collect crop material laying on the ground in a windrow, the baler 10 may include a pickup mechanism 22, as perhaps best illustrated in
The rotor housing 24 may also be positioned below the baling chamber 18 and is generally configured to rotatably support a rotor 26 within the rotor housing 24. The rotor 26 is shown in more detail in
Returning to the rotor housing 24 and the rotor 26, the rotor housing 24 and/or the rotor 26 may be particularly configured to direct crop material received from the pickup mechanism 22 generally evenly into each stuffer chute 28 of the baler 10. For example, as illustrated by
In some embodiments, the rotor 26 may further comprise a first exterior auger-flighted section 40 and a second exterior auger-flighted section 42 positioned on either end of the spindle 30. As such, the first toothed section 32 may be situated between the first exterior auger-flighted section 40 and the interior auger-flighted section 36 (e.g., the first set of interior flights 38). Similarly, the second toothed section 34 may be situated between the second exterior auger-flighted section 42 and the interior auger-flighted section 36 (e.g., the second set of interior flights 39). As such, the first exterior auger-flighted section 40 is configured to push crop material inwardly toward the first toothed section 32, whereas the second exterior auger-flighted section 42 is configured to push crop material inwardly toward the second toothed section 34. State differently the first exterior auger flighted section 40 is configured to push crop in a first direction and the second set of interior flighted section 42 is configured to push crop in a second direction generally opposite the first direction.
To further facilitate the distributions and processing of crop material, some embodiments of the baler 10 may include a stationary separation element 44 extending upward from a bottom panel of the rotor housing 24. In some embodiments, the separation element 44 may have a sharpened forward edge so as to act as a blade-like dividing member for cutting crop material that is forced into contact with the separation element 44. In some embodiments, the rotor 26 may include a gap between the first and second sets of interior flights 38, 39 of the interior auger-flighted section 36, such that the separation element 44 can be at least partly received in the gap as the rotor 26 rotates. In some further embodiments, the rotor 26 may further comprise a first interior tooth 46 and second interior tooth 48, which are both positioned between the first and second sets of interior flights 38, 39 of the interior auger-flighted section 36. In some embodiments, the first and second interior teeth 46, 48 may be spaced apart from each other so as to present the gap between the first and second sets of interior flights 38, 39 of the interior auger-flighted section 36. As such, the first set of interior flights 38 may terminate at the first interior tooth 46, while the second set of interior flights 39 may terminate at said second interior tooth 48. Thus, in such embodiments, the first and second interior teeth 46, 48 may be configured to pass on either side of the separation element 44 when the rotor 26 is rotating.
Given the above-described rotor 26 and the separation element 44, embodiments provide for crop material provided to the rotor housing 24 by the pickup mechanism 22 to be directed generally evenly to each of the stuffer chutes 28. In more detail, the baler 10 may, as illustrated in the
To evenly distribute the crop material to the stuffer chutes 28, the first toothed section 32 of the rotor 26 may be aligned with the left-side stuffer chute 28, and the second toothed section 34 of the rotor 26 may be aligned with the right-side stuffer chute 28. As such, when the rotor 26 is rotated (e.g., generally in a counter-clockwise direction when viewing from the left side of the baler 10, as in
Thus, the baler 10 is particularly configured to collect crop material from a single windrow and process such crop material into a plurality of crop streams. For example, in embodiments that include two baling chambers 18, the crop material may be provided in a first crop stream to a first of the stuffer chutes 28 (e.g., the left-side stuffer chute 28), and in a second crop stream to a second of the stuffer cutes 28 (e.g., the left-side stuffer chute 28). As will be described in more detail below, crop material from the first crop stream may be transferred through the left-side stuffer chute 28 to the left-side baling chamber 18 for formation of bales of crop material. Similarly, crop material from the second crop stream may be transferred through the right-side stuffer chute 28 to the right-side baling chamber 18 for formation of bales of crop material.
In some embodiments, each of the stuffer chutes 28 may be associated with stuffer assembly 50, as shown in
Upon introduction of a charge of crop material into one of the baling chambers 18, the baler 10 is configured to further compress the crop material into a square bale of crop material. As illustrated in
As illustrated in
In more detail, and with reference to
In some embodiments, a cross-sectional area of each baling chamber 18 may decrease moving from a forward end to a rearward end of the baling chamber 18. Such a reduction in a cross-sectional area can facilitate the ability of the baling chambers 18 to compress the crop material into square bales during formation of the bales. As such, the baling chambers 18 may be configured to exert pressure on all four sides of the bales as the bales move rearward through the baling chambers 18. Furthermore, in some embodiments, each baling chamber 18 may include an independent compression assembly 60, as shown in
As noted above, the baler 10 according to embodiments of the present invention may include a plurality of baling chambers 18, each being configured to generate individual square bales of crop material. As such, the baler 10 can simultaneously form multiple square bales from crop material obtained from a single windrow. In some embodiments, as illustrated in the figures, the baler 10 will include two spaced apart, side-by-side baling chambers 18. Such baling chambers 18 may extend in a generally fore-and-aft direction with respect to the chassis 12. The baling chambers 18 may extend in a generally parallel relationship with each other (and/or with the longitudinal centerline of the of the chassis 12 and/or the baler 10), with one baling chamber 18 positioned on one side of the longitudinal centerline of the chassis 12 of the baler 10, and the other baling chamber 18 positioned on the other side of the longitudinal centerline of the chassis 12 of the baler 10. In some embodiments, the baling chambers 18 may be spaced from one another by not more than sixty inches, not more than forty-eight inches, not more than thirty-six inches, or not more than twenty-four inches. In alternative or additional embodiments, the baling chambers 18 may be spaced from one another by at least one inch, at least three inches, at least six inches, at least twelve inches, or at least eighteen inches. Beneficially, having the baling chambers 18 spaced apart can make it simpler to implement mechanisms that handle, accumulate, and/or sort bales that are formed in and dispensed from the baling chambers 18.
In alternative embodiments, the baling chambers 18 may not be spaced apart from each other. For example, the baling chambers 18 may be separated by (or share) a common interior wall, such that no air gap exists between the baling chambers 18. For example, the common interior wall may comprise the interior sidewall 54 of the adjacent baling chambers 18, such that the baling chambers 18 are not spaced apart. In some embodiments, an entire length of the baling chambers 18 may be separated by the common interior wall.
In some further embodiments, the baling chambers 18 may not be separated by any interior walls. For example, four walls (e.g., a pair of sidewalls 54, a top wall 56, and a bottom wall 58) may define a common interior baling space that includes two baling chambers 18. As such, the two baling chambers 18 can share a common interior baling space so that two bales can be simultaneously formed within the common interior baling space.
As was noted above, each of the baling chambers 18 may include a plunger 52 for compacting crop material in the baling chamber 18 to form a square bale of crop material. In an embodiment of the baler 10 that include two baling chambers 18, as shown in the figures, the baler 10 may include two plungers 52 (See, e.g.,
In some embodiments, as shown in
In general, the gearbox 70 is configured as a rotating power source that is used to rotate the first and second drive shaft sections 76, 78 using power from the external rotating power source, e.g., the power take-off 72. In some embodiments, the gearbox will be configured to rotate the first and second drive shaft sections 76, 78 at generally equal speeds (i.e., at equivalent rates of rotation). In embodiments of the baler 10 that include two plungers 52, as illustrated in
Under power from the gearbox 70, rotation of the first drive shaft section 76 will cause reciprocation of the left-side plunger 52 and rotation of the second drive shaft section 78 will cause reciprocation of the right-side plunger 52. As was described previously, each of the plungers 52 is configured to reciprocate between the extended position and the retracted position. The gearbox 70 may, in some embodiments, be configured to actuate the plungers 52, such that the left-side and right-side plungers 52 are reciprocated in an alternative fashion. As such, when the left-side plunger 52 is in the extended position, the right-side plunger 52 is in the retracted position, and vice versa. Such positioning may be facilitated by the connecting elements 80 being orientated generally one-hundred eighty degrees out of phase (in certain embodiments with two plungers 52). For instance, as shown in
In some embodiments, a point of connection between the left-side plunger 52 and the left-side connecting element 80 will be spaced from the axis of rotation of the first drive shaft section 76, such that the connection may be eccentrically shaped (i.e., the connecting element 80 may be an eccentric connection). In some embodiments, the first drive shaft section 76 may terminate at the left-side connecting element 80. In addition, in some embodiments, the point of connecting between the right-side plunger 52 and the right-side connecting element 80 will be spaced from the axis of rotation of the second drive shaft section 78, such that the connection may be eccentrically shaped (i.e., the connecting element 80 may be an eccentric connection). In some embodiments, the second drive shaft section 78 may terminate at the right-side connection element 80.
As was briefly noted above, in some embodiments, the left-side and right-side connecting elements 80 may be rotationally offset from one another with respect to the rotation of the first and second drive shaft sections 76, 78. In some specific embodiments, the left-side and right-side connecting elements 80 may be rotationally offset from one another by about one-hundred eighty degrees, about one-hundred twenty degrees, or about ninety degrees with respect to the axes of rotation of the first and second drive shaft sections 76, 78. In other embodiments, the left-side and right-side connecting elements 80 may be rotationally aligned with one another with respect to the axes of rotation of said first and second drive shaft sections 76, 78. In further embodiments, the relative rotational positioning of the left-side and right-side connecting elements 80 with respect to the rotation of said first and second drive shaft sections 76, 78 may either be i) aligned with one another or ii) offset from one another by an amount of rotational degrees approximately equal to three-hundred and sixty divided by the total number of reciprocating plungers 52 included in the baler 10. Thus, in embodiments of the baler 10 that include two plungers 52, the relative rotational positioning of the left-side and right-side connecting elements 80 with respect to the rotation of said first and second drive shaft sections 76, 78 may be about one-hundred and eighty degrees. Nevertheless, it should be understood that in some embodiments, the baler 10 may include more than two plungers 52, such that the connecting element 80 may be offset by different magnitudes.
In some further embodiments of the gearbox 70, the first drive shaft section 76 may include an auxiliary drive shaft 84, as perhaps best illustrated in
For example, as illustrated in
As described above, in certain embodiments, the baler 10 may include two stuffer assemblies 50. In some of such embodiments, one of the stuffer assemblies 50 (e.g., the left-side stuffer assembly 50) may be connected with the other stuffer assembly 50 (e.g., the right-side stuffer assembly 50), such that rotation of the left-side stuffer assembly 50 will cause a corresponding rotation of the right-side stuffer assembly 50. For example, as illustrated in
Some embodiments provide for the left-side and right-side stuffer assemblies 50 to be offset by one-hundred and eighty degrees. As such, for instance, when the left-side stuffer assembly 50 is in an upward or top position, the right-side stuffer assembly 50 will be in the lower or bottom position. In addition, the position of the stuffer assemblies 50 may, in some embodiments, correspond with the positions of the plungers 52. For example, when the left-side stuffer assembly 50 is in the upward or top position, the left-side plunger 52 will be in the retracted position, such that crop material may be fed into the left-side baling chamber 18 by the left-side stuffer assembly 50. In such a configuration, the right-side stuffer assembly 50 will be in a lower or bottom position and the right-side plunger 52 will be in the extended position. As such, when the left-side stuffer assembly 50 is in the top position, the left-side plunger 52 will correspondingly be in the retracted position, such that crop material may be fed into the left-side baling chamber 18 from the left-side stuffer chute 28 by the left-side stuffer assembly 50 in preparation for compression stroke by the left-side plunger 52 to form a compacted square bale within the left-side baling chamber 18.
From the configuration discussed above, the gearbox 70 can rotate the stuffer assemblies 50, e.g., via the connection (e.g., the chains and sprockets) between the auxiliary drive shaft 84 and the stuffer assemblies 50 (e.g., via the drive input assembly 86), such that the right-side stuffer assembly 50 is shifted to the top position and the left-side stuffer assembly 50 is shifted to the bottom position. During such actuation, the gearbox 70 can simultaneously shift the right-side plunger 52 (e.g., via the second drive shaft element 78) to the retracted position and the left-side plunger 52 (e.g., via the first drive shaft element 76) to the extended position. As such, when the right-side stuffer assembly 50 is in the top position, the right-side plunger 52 will correspondingly be in the retracted position, such that crop material may be fed into the right-side baling chamber 18 by the right-side stuffer assembly 50 in preparation for compression stroke by the right-side plunger 52 to form a compacted square bale within the right-side baling chamber 18. In such a configuration, the left-side stuffer assembly 50 will be in the bottom position and the left-side plunger 52 will be in the extended position. As such, while the right-side plunger 52 is compacting crop material to form a bale, the left-side stuffer assembly 50 is in the downward position preparing to collect and push crop material upward through the left-side stuffer chute 28 once the left-side plunger 52 has been retracted.
In some embodiments, as shown in
In addition to the auxiliary driven mechanisms discussed above, some embodiments of the baler 10 may include a plurality of knotter assemblies 90, as shown in
In addition, each of the knotter assemblies 90 may include one or more needles 94, as illustrated in
As illustrated in
Embodiments provide for the trip mechanism 96 of each knotter assembly 90 to be particularly configured (e.g., due to a size of the starwheel 98 and/or to additional configurations of the measuring assembly 100) so as to initiate the tying of knots of the securement lines by each knotting mechanism 92 of the knotter assembly 90 once a bale has been fully formed to the appropriate size (e.g., the appropriate length). Broadly, the measuring assembly 100 will be configured to measure a size and/or length of bales being formed in the baling chambers 18. In more detail, as a bale of crop material is being formed in a baling chamber 18 (i.e., via the cyclical compressions of flakes of crop material by the reciprocating plunger 52), the bale will travel rearward through the baling chamber 18. In embodiments in which each knotter assembly 90 includes two knotting mechanisms 92, each knotting mechanism 92 will hold a securement line, such that the two securement lines will extend downward through the baling chamber 18 to tips of the respective needle 94. As the bale travels rearward, the two securement lines will wrap against a rear surface of the bale, as well as over a top and bottom of the bale, as illustrated in
In some alternative embodiments, the baler 10 may include trip mechanisms 96 that comprise electronic measuring assemblies that may include electrical and/or electro-mechanical components. For example, each starwheel 98 may be associated with an electronic sensor for measuring a length of the bale passing through the relevant baling chamber 18. The electronic sensor may be a rotary encoder, an optical sensor, or the like. The electronic sensor may measure the length of the bale passing through the associated baling chamber 18, and the resulting bale length data may be provided to an electronic control unit positioned on the baler 10 or on the tow vehicle The electronic control unit may include memory elements and processing elements configured to analyze the bale length data for a bale and to send resulting instructions to the clutch mechanism 104 upon the bale reaching a pre-determined bale length. In more detail, the electronic sensor may obtain bale length data for a given bale and may provide such bale length data to the electronic control unit. Upon the electronic control unit determining from the bale length data that the given bale has reached a fully-formed length (as may be pre-determined/pre-defined), the electronic control unit may send a signal or instruction to the clutch mechanism 104 to cause actuation of the knotting mechanisms 92 and related needles 94 so as to tie off securement lines around the fully formed bale. In embodiments in which the baler 10 includes multiple baling chambers 18 (each having its own starwheel 98 and clutch mechanism 104), each starwheel 98 may include its own electronic sensor for measuring the lengths of the bales being formed in its associated baling chamber 18. The electronic control unit may receive bale length data from each electronic sensor and may send independent instructions to each clutch mechanism 104 to tie off the bales in each baling chamber once each bale has been fully formed to the pre-determined bale length.
Beneficially, the knotter assemblies 90 of the baler 10 are configured to operate independently of one another. As such, the bales being formed in each of the baling chambers 18 can be wrapped and tied at different times, when the bales have been fully formed. For example, if two bales are being formed in the baler 10, one in the left-side baling chamber 18 and one in the right-side baling chamber 18, the left-side knotter assembly 90 can tie off the securement lines around the bale being formed in the left-side baling chamber 18 when the bale is fully formed (i.e., to the predetermined bale length), and the right-side knotter assembly 90 can tie off the securement lines around the bale being formed in the right-side baling chamber 18 when the bale is fully formed (i.e., to the predetermined bale length). However, because such bales may become fully formed at different times, e.g. due to variations in the amount of crop material being provided to the individual baling chambers 18, the knotter assemblies 90 associated with each baling chamber 18 may initiate tying of the securement lines at different times. As such, the baler 10 can be prevented from tying of short (or long) bales, which can create problems with stacking, transporting, and retailing of such bales. The independent operation of the knotter assemblies 90 will be described in further detail below.
In operation, the baler 10 described above may be configured to simultaneously produce multiple bales of crop material from a single windrow. The number of bales that may be simultaneously formed by the baler 10 is at least partly dependent on the number of baling chambers 18 included in the baler 10. As discussed above, the baler 10 may include a plurality of baling chambers 18. The embodiments shown in the drawings illustrate the baler 10 including two, inline baling chambers 18. However, it should be understood that certain embodiments of the baler 10 may include more than two baling chambers 18 (e.g., three, four, five, six, or more). In general, the baler 10 will be equipped with a number of stuffer chutes 28, stuffer assemblies 50, plungers 52, and knotter assemblies 90 that corresponds with and/or that is equal to the number of baling chambers 18. As such, the baler 10 will be configured to adequately provide crop material to each of the baling chambers 18 to create the bales of crop material.
The following example illustrates a baler 10 with a pair of baling chambers 18, which can be used to simultaneously form multiple square bales of crop material. As the baler 10 is pulled along its path of travel by the tow vehicle, the pickup mechanism 22 can pick up crop material from a single windrow of crop material. Particularly, the plurality of tines extending from the rotating member of the pickup mechanism 22 functions to pick up the crop material from the ground and to force the crop material upwardly and rearwardly to the rotor housing 24, with such flow of crop material illustrated by the arrows of
While the crop material is in the stuffer chutes 28, the stuffer assemblies 50 of the stuffer chutes 28 will function to propel the crop material rearward and upward from the lower entrances of the stuffer chutes 28 to the upper exits of the stuffer chutes 28, as illustrated in
As such, in the embodiment of the baler 10 illustrated in the drawings (i.e., with two stuffer chutes 28, two stuffer assemblies 50, two baling chambers 18, and two plungers 52), the left-side stuffer assembly 50 can be rotated upward, due to actuation caused by the gearbox 70, so as to force a charge of crop material from into the crop inlet of the left-side baling chamber 18 (with the crop inlet being positioned on a bottom/forward side of the left-side baling chamber 18) while the left-side plunger 52 is in a retracted position. In such a configuration, the right-side stuffer assembly 50 will be in a lowered position and the right-side plunger 52 will be in an extended position. With a charge of crop material being added into the left-side baling chamber 18, the gearbox 70 can actuate the left-side plunger 52 to the extended position to compress the charge of crop material into flake of a bale of crop material. Such extension of the left-side plunger 52 will be accompanied, due to actuation caused by the gearbox 70, by a shifting of the right-side plunger 52 from the extended position to the retracted position. Simultaneously, the right-side stuffer assembly 50 can be rotated upward, due to actuation caused by the gearbox 70, so as to force a charge of crop material into the crop inlet of the right-side baling chamber 18 (with the crop inlet being positioned on a bottom/forward side of the right-side baling chamber 18) while the right-side plunger 52 is in a retracted position. With a charge of crop material being added into the right-side baling chamber 18, the gearbox 70 can actuate the right-side plunger 52 and can be extended to compress the charge of crop material into flake of a bale of crop material. Such actions can be repeated in a cyclical manner, as driven by the gearbox 70, so as to simultaneously form square bales of crop material in each of the left-side and right-side baling chambers 18.
As the bales are moving through each of the baling chambers 18 (e.g., the left-side and right-side baling chambers), the knotter assemblies 90 are configured to wrap and tie securement lines securely around the bales so as to hold the flakes of the bales together. Specifically, a left-side knotter assembly 90 may use its pair of knotting mechanisms 92 to wrap a pair of securement lines around the bales of crop material passing rearward through the left-side baling chamber 18. Upon the bale reaching the predetermined length, the trip mechanism 96 of the left-side knotter assembly 90 may cause the pair of needles 94 and the pair of knotting mechanisms 92 of the left-side knotter assembly 90 to actuate to complete the wrapping of the securement lines around the bale passing rearward through the left-side baling chamber 18 and to tie off the securement lines securely onto the bale. Similarly, a right-side knotter assembly 90 may use its pair of knotting mechanisms 92 to wrap a pair of securement lines around the bales of crop material passing rearward through the right-side baling chamber 18. Upon the bale reaching the predetermined length, the trip mechanism 96 of the right-side knotter assembly 90 may cause the pair of needles 94 and the pair of knotting mechanisms 92 of the right-side knotter assembly 90 to actuate to complete the wrapping of the securement lines around the bale passing rearward through the right-side baling chamber 18 and to tie off the securement lines securely onto the bale.
As was noted previously, the left-side and right-side knotter assemblies 90 may operate independently and at different times. To facilitate such independence, certain embodiments provide for the gearbox 70 to independently provide rotational power to each of the knotter assemblies 90. For example, in some embodiments, the auxiliary drive shaft 84 extending from the lift-side of the gearbox 70 may be connected (e.g., via chain and sprocket) to the sprocket 105 of the clutch mechanism 104 of the left-side knotter assembly 90. The sprocket 105 can, thus, be constantly driven by the auxiliary drive shaft 84 of the gearbox 70, such that the rotatable shaft 93 of the left-side knotter assembly can be actuated (in addition to the needles 94 of the left-side knotter assembly 90) when engaged by the clutch mechanism 104 upon command from the measuring assembly 100 of the left-side knotter assembly 90. Certain embodiments may provide for the right-side knotter assembly 90 to be driven in a similar manner by a second auxiliary drive shaft (not shown) extending from a right-side of the gearbox 70, such that the left-side and right-side knotter assemblies 90 may operate independently and at different times.
Alternatively, as illustrated in
Upon the bales of crop material being completely formed and tied off with securement lines, the bales may be ejected from ejection ports of the baling chambers 18. In some embodiments, the bales from each of the left-side and right-side baling chambers 18 will be ejected from the bale discharges of their respective baling chambers 18 in an alternating fashion. For example, due to the cyclical, reciprocating action of the left-side and right-side plungers 52, bales of crop material formed in the left-side baling chamber 18 may be completed in an alternating time periods with respect to bales formed in the right-side baling chamber 18. As such, the bales of crop material formed in the left-side and the right-side baling chambers 18 may be ejected in an alternating fashion. In different embodiments, the bales of crop material formed in the left-side baling chamber 18 may be ejected generally simultaneously as bales formed in the right-side baling chambers 18.
Although the invention has been described with reference to the one or more embodiments illustrated in the figures, it is understood that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims. For example, the baler 10 illustrated and described above may be considered an “in-line” square baler, wherein the pickup mechanism 22, the stuffer chutes 28, the plungers 52, and the baling chambers 18 are orientated and/or aligned generally along fore-and-aft direction. As such, crop material is picked up from the windrow can flows in a generally in-line manner from the pickup mechanism 22 and the stuffer chutes 28 to the baling chambers 18. Regardless, the principles of the present invention may be equally applicable to various other square and rectangular baler designs. For example, it is contemplated that embodiments of the present invention may utilize a pickup mechanism 22 that is offset from (e.g., to one side of) the baling chambers 18.
The individual bales formed by the baler 10 may be ejected from the baling chambers 18 in series. For example, the left side baling chamber 18 may eject a first series of first individual bales (i.e., bales formed in a single row), while the right side baling chamber 18 may eject a second series of second individual bales (i.e., bales formed in a single row). Unfortunately, it can be cumbersome and time consuming to pick up and/or process bales formed in multiple series or rows. As such, embodiments of the present invention may further comprise a bale singulating system, such as singulator 200 illustrated in
Before describing the singulator 200, it should be understood that the baler 10 can include multiple baling chambers 18 for simultaneous forming multiple individual rows of bales. For example, the embodiments shown in the drawings include two baling chambers 18, namely, a left side baling chamber 18 and a right side baling chamber 18. Each of the baling chambers 18 may present a bale-forming area in which the bales of crop material may be formed. However, it should also be understood that certain embodiments of the baler 10 may include a single baling chamber 18 that presents multiple bale-forming areas therein. For example, some embodiments of the baler 10 may include a single baling chamber 18 in which crop material is fed and separated by a knife to form two bales, with one bale being formed in one of two bale-forming areas defined within the single baling chamber 18 (i.e., one bale-forming area on either side of the knife). The baler 10 may, therefore, simultaneously form two individual bales (one bale in each bale-forming area), perhaps through use of two plungers 52 in a manner similar to that described above. In further embodiments, the single baling chamber 18 may have more than one knife, such that the single baling chamber 18 may include more than two bale-forming areas for simultaneously forming more than two bales. For example, the single baling chamber 18 may include two knives for simultaneously forming three bales within three bale-forming areas contained within the single baling chamber 18. In embodiments of the baler 10 that includes “n” number of knives within a single baling chamber 18, the baler 10 may simultaneously form “n+1” number of bales within “n+1” number of bale-forming areas presented by the single baling chamber 18.
As used herein, the term bale-forming area may refer to a single area bounded by the walls 54, 56, 58 of a single baling chamber 18, such that each baling chamber 18 of the baler 10 defines a single bale-forming area. Alternatively, the term bale-forming area may refer to one of a plurality of areas, the plurality of which are bounded by the walls 54, 56, 58 of a single baling chamber 18. Correspondingly, embodiments of the present invention provide for each baling chamber 18 of the baler 10 to include one or more bale-forming areas defined therein. In embodiments that include a plurality of bale-forming areas within a single baling chamber 18, each bale-forming area may be bound by one or more of the walls 54, 56, 58 of the baling chamber 18 and by a knife of the baling chamber 18. For example, in embodiments in which two bale-forming areas are included within a single baling chamber 18 comprising a single knife, a first/left side bale-forming area may be bound by a left sidewall 54, a top wall 56, a bottom wall 58, and the knife. Similarly, a second/right side bale-forming area may be bound by a right sidewall 54, a top wall 56, a bottom wall 58, and the knife. Once the crop material passes by the knife, the bales being formed in the first/left and second/right bale-forming areas may be adjacent to and contact each other as the bales continue to pass through the baling chamber 18.
As such, in certain embodiments in which a plurality of bale-forming areas are presented within a single baling chamber 18, the bale-forming areas may not be separated from each other. Instead, the bale-forming areas may be situated adjacent to each other with no space therebetween. However, as noted above, the bale-forming areas may be at least partly separated by the knife described above. In contrast, in embodiments in which each baling chamber 18 includes a single bale-forming area, the bale-forming areas may be separated from each other (e.g., by a space). In more detail, as described above with respect to the embodiments of the baler 10 that include two baling chambers 18, the left side baling chamber 18 may be separated by a space from the right side baling chamber 18. As such, the bale-forming areas within the left and right side baling chambers 18 may likewise be separated from each other.
Turning now to the singulator 200, as illustrated by
Turning to the singulator 200 in more detail, and with reference to
In some embodiments, the landing section 202 may be secured to the rearward ends of the baling chambers 18 and positioned directly below the outlets of the baling chamber 18. For example, as shown in
The exit section 204 may be secured to a rear side of the landing section 202, such that the singulating section is located behind the landing section 202. The exit section 204 may be orientated generally parallel with the landing section 202 such that the exit section 204 may be oriented at angle of decline as it extends from front to back. In some embodiments, the exit section 204 may be pivotally connected to a rear side of the landing section 202 such that the singulating section may be selectively orientated at a steeper angle than the landing section 202. Given the declination orientation of the exit section 204, the bales received on the exit section 204 from landing section 202 can slide rearward on the exit section 204 under the force of gravity
As will be discussed in more detail below, embodiments of the singulator described herein may include various transport mechanisms for moving the first and second individual bales from the landing section to the exit section and off the exit section. In addition to the use of gravity as described above (e.g., via gravity slide or a gravity dump), certain embodiments may include a transport mechanism selected from one or more of the following: a pushing element and a conveyor. For instance, the landing section 202 may be positioned generally horizontally and may include a conveyor mechanism for moving the bales from the landing section 202 to the exit section 204. An embodiment of a singulator that includes such a conveyor mechanism is described in more detail below.
Once the bales arrive at the exit section 204, the exit section 204 may be configured to manipulate the bales into a single, linear row of bales. For example, the singulator 200 may comprise, as illustrated in
In more detail, the pusher members 210 may comprise elongated tubular members formed from metal or another material with sufficient strength and durability. The exit section 204 may include one pusher member 210 secured on either lateral side of the exit section 204. As perhaps best shown in
In such a configuration, as illustrated by
As perhaps best shown in
Finally, it should be noted that in some embodiments, the singulator 200 may be folded forward adjacent to the remaining components of the baler 10 (e.g., adjacent to the baling chamber 18 and/or the chassis 12) for convenience during transport of the baler 10. For example, the connection between the landing section 202 and the baling chambers 18 may allow for the landing section 202 to be pivoted upward/downward and adjacent to the baling chambers 18 and/or to the chassis 12. Similarly, the exit section 204 may be pivoted upward/downward and adjacent to the landing section 202. Such shifting/folding of the landing section 202 and the exit section 204 reduces the footprint of the baler 10, which can aid in transport and storage of the baler 10.
An additional embodiment of a singulator 220 is illustrated in
The other components of the singulator 220 may include a landing section 222 and an exit section 224. The landing section 222, on which first and second individual bales may be deposited by the left and right baling chambers 18 (and/or by the first/left and second/right bale-forming areas), respectively, may comprise a first dump cradle 226 (e.g., a left side dump cradle) and a second dump cradle 228 (e.g., a right side dump cradle), each movable between a bale-receiving position and a bale-dumping position.
The dump cradles 226, 228 may be supported in positions adjacent to the rear of the baling chambers 18 via upright supports that extend upward from the chassis extension 221. As such, the landing section 222 (which includes the dump cradles 226, 228) may be positioned above the exit section 224, as will be discussed in more detail below.
Each of the dump cradles 226, 228 may comprise an elongated base panel that is rotatably connected to one or more of the of the upright supports. The base panels may have a length that is generally the same length as (or longer than) a bale being formed by the baler. The dump cradles 226, 228 may be actuated between the bale-receiving and the bale-dumping positions (and vice versa) via dump actuators that extend from the upright supports to the dump cradles 226, 228. In some embodiments, the dump actuators may comprise hydraulic cylinders. As such, the singulator 220 may be associated with a hydraulic system (e.g., a pump, a reservoir, lines, etc.) for selectively providing hydraulic power to the cylinders. In some embodiments, the upright supports may each also include an elongated side support panel that works in cooperation with a respective dump cradle 226, 228 to support a bale. Specifically, when the dump cradles 226, 228 are in the bale-receiving position, the base panels are generally horizontal so as to be able to support a bale (in conjunction with the side support panels). In contrast, when the dump cradles 226, 228 are in the bale-dumping position, the base panels are shifted (i.e., rotated downward) to a non-horizontal or a downwardly oriented position, such that the dump cradles 226, 228 will not support a bale and the bale will drop down onto the exit section 224.
In more detail, when in the bale-receiving position, each of the dump cradles 226, 228 may be configured to support an individual bale ejected from one of the baling chambers 18. To facilitate the reception of the bales, the dump cradles 226, 228 may be positioned directly rearward and/or below the baling chambers 18, with the left side dump cradle 226 rearward and/or below of the left side baling chamber 18 and the right side dump cradle 228 positioned rearward and/or below of the right side baling chamber 18. As such, when the left side dump cradle 226 is in the bale-receiving position (See, e.g.,
Each of the dump cradles 226, 228 may include a sensor 229 for determining when a bale has been completely received on a given dump cradle 226, 228 from the respective baling chamber 18. The sensors 229 may comprise electro-mechanical switches positioned on rearward ends of the dump cradles 226, 228, as shown in
In operation of the baler 10, a bale being ejected from a bailing chamber 18 will slide rearward on a dump cradle 226, 228. Once the bale has been completely ejected onto a dump cradle 226, 228, the bale will make contact with the sensor 229 (i.e., shifting the cover panel rearward over the base element), which will provide an indication that the bale has been completely received on the dump cradle 226, 228. In some embodiments, the sensors 229 may be in communication with the dump actuators that will cause the dump cradle 226, 228 to transition from the bale-receiving position to the bale-dumping position when a bale has been completely received on the dump cradle 226, 228. Alternatively, the sensors 229 may be in communication with a control system (not shown) that instructs the dump cradles 226, 228 to transition from the bale-receiving position to the bale-dumping position when a bale has been completely received on the dump cradle 226, 228.
Turning now to the exit section 224 in more detail, as perhaps best shown in
In some embodiments, as perhaps best illustrated by
Finally, the exit section 224 may include a funnel outlet 238, as illustrated in
In operation, the singulator 220 can receiving first and second individual bales from the baling chambers 18 (and/or from the baling areas) and manipulate the individual bales such that the individual bales are configured in a single row of bales. In more detail, as shown in
In some embodiments, the first individual bale will be forced out of the funnel outlet 238 and onto the ground via actuation of the conveyor 232. However, in some other embodiments, the first individual bale may remain on or in the funnel outlet 238 until a subsequent bale forces the first individual bale off the funnel outlet under power form the conveyor 232.
The above process for moving the first individual bale rearward through the singulator 220, as shown in
In some embodiments, the singulator 220 may be associated with a control system for controlling certain functionality of the singulator 220. The control system may comprise one or more processing elements and/or memory elements. The memory elements may store a computer program or application, which when executed by the processing elements, functions to control such certain operations of the singulator 220. In particular, the control system may be functionally coupled with the sensors 229, the switches 236, the dump cradles 226, 228, and/or the conveyor 232 such that the control system may receive information from such components and provide resulting instructions to such components. As was noted previously, the baling chambers 18 (and/or the bale-forming areas) may be configured to form individual bales simultaneously. However, the individual bales may be completed within and eject from the baling chambers 18 (and/or the bale-forming areas) at different times. For instance, the left side baling chamber 18 (and/or the first/left bale-forming area) may finish forming a first individual bale and may eject the individual bale onto the left side dump cradle 226. Thereafter (e.g., 10 seconds later), the right side baling chamber 18 (and/or the second/right bale-forming area) may finish forming a second individual bale and may eject the bale onto the right side dump cradle 228. Nevertheless, some operational conditions may allow for the left and right baling chambers 18 (and/or the first/left and second/right bale-forming areas) to finish forming individual bales at nearly the same time, such that the left and right baling chambers 18 (and/or the first/left and second/right bale-forming areas) will eject the individual bales onto the dump cradles 226, 228 at nearly the same time.
It may be problematic if multiple bales are dropped by the dump cradles 226, 228 at the same time onto the receiving tray 230, as jamming of the singulator 220 may occur. To address such concerns, the control system may be configured control operation of the singulator 220 to ensure that only one individual bale is dumped onto the receiving tray 230 at a time. For instance, with the first individual bale being supported on the left side dump cradle 226 in the bale-receiving position, the first individual bale may trip the sensor 229 associated with the left side dump cradle 226. The sensor may provide an indication (e.g., a signal) to the control system that the first individual bale is completely received on the left side dump cradle 226, and the control system may instruct the left side dump cradle 226 to shift to the bale-dumping position so as to dump the first individual bale onto the receiving tray 230. As the first individual bale is dumped onto the receiving tray 230, the bale will be forced laterally inward toward a center of the receiving tray 230 due to the inwardly/downwardly sloping sidewalls of the receiving tray 230. The first individual bale will, thus, make contact with one (or both) of the switches 236, which will send an indication (e.g., a signal) to the control system of the centered positioning of the bale on the receiving tray 230. As such, the control system will instruct the conveyor 232 to activate such that the paddle 234 will push the first individual bale rearward across and off the receiving tray 230 and onto the funnel outlet 238.
During such activity with respect to the first individual bale, the right dump cradle 228 may be in the bale-receiving position and may be supporting a second individual bale that was ejected from the right side baling chamber 18 (and/or the second/right bale-forming area). The second individual bale may be completely positioned on the second dump cradle 228, such that the bale has tripped the sensor 229 associated with the right dump cradle 228. As such, the sensor 229 may provide an indication (e.g., a signal) to the control system that the second individual bale is completely received on the right dump cradle 228. However, the control system may be configured to not instruct the right dump cradle 228 to shift to the bale-dumping position until the first individual bale has been completely moved off the receiving tray 230. In particular, the control system may be configured to not instruct the right dump cradle 228 to shift to the bale-dumping position until the conveyor 232 has been activated for one-half of a rotation, at which time the first individual bale has been pushed rearward off the receiving tray 230 by a first paddle 234 of the conveyor 232. As such, the receiving tray 230 will be generally empty and a second paddle 234 will be positioned at a forward end of the receiving tray 230, such that the receiving tray 230 is open to receive the second individual bale from the right side dump cradle 228, such that the second individual bale can be pushed rearward by the second paddle 234 of the conveyor 232. In such a manner, the control system may control operation of the singulator 220 in a manner that manipulates first and second individual bales into a single line of bales without the singulator 220 becoming jammed.
In some further embodiments, the singulator 220 may be incorporated with a scale or other sensor for measuring a weight of individual bales. In some embodiments, the scales may be incorporated within the landing section 222. For instance, each of the dump cradles 226, 228 may include or be associated with a scale to measure a weight of each bale supported on the dump cradle 226, 228. Alternatively, the scales may be incorporated within the exit section 224. For instance, the receiving tray 230 be associated with a scale to measure a weight of each bale supported thereon. The scales may be communicatively coupled with the control system to use resulting weight data in furtherance of control of the singulator 220. The weight data may also be stored for further analysis by the operator of the baler 10.
A further embodiment of a singulator 240 is illustrated in
Each of the lift cradles 246, 248 may comprise one or more base supports and one or more side supports. In some embodiments, the base supports and side supports may be formed from a single piece of material formed in an “L” shape. The lift cradles 246, 248 may each be associated with an actuator (e.g., a hydraulic cylinder) that functions to rotate and raise its respective lift cradle 246, 248 laterally inward and upward from the bale-receiving position to the bale-ejecting position. The lift cradles 246, 248 may be rotatably connected to the baling chambers 18, the chassis 12, and/or the exit section 244 in a manner that allows the lift cradles 246, 248 to be rotated/raised to the bale-ejecting positions in which the lift cradles 246, 248 are positioned at least partially above the exit section 244.
When the lift cradles 246, 248 are in the bale-receiving position, the base supports are generally horizontal so as to be able to support a bottom portion of the bales, while the side supports are oriented vertically to support a side surface of the bales. In the bale-receiving position, the lift cradles 246, 248 will be positioned below at least part of the exit section 244. In contrast, when the dump cradles 226, 228 are rotated/raised to the bale-dumping position, the base supports and the side supports are shifted (i.e., rotated upward) to non-horizontal and non-vertical positions, respectively, such that the lift cradles 246, 248 will not support the bales and the bales can be deposited onto the exit section 244.
The exit section 244 present a central platform comprising a main central platform 250 that is configured to receive individual bales. The main central platform 250 may be sufficiently wide to only receive a single individual bale. The exit section 244 may further include an outlet slide 252 that is connected to a rearward end of the main central platform 250. The individual bales may be moved from the main central platform 250 to the outlet slide 252 via a conveyor or other type of pushing element. Once on the outlet slide 252, the bales can slide rearward under the force of gravity and off the singulator 240 onto the ground. Alternatively, the main central platform 250 may be configured to be rotated downward (e.g., under power of a hydraulic cylinder) so as to be selectively orientated at a declination angle that matches that of the outlet slide 252. As such, when the main central platform 250 is rotated downward, a bale can slide rearward off the main central platform 250 under the force of gravity and on to the outlet slide 252, where the bale can continue sliding down and off the singulator 240. As such, the singulator 240 is configured to receive first and second individual bales from the left and right side baling chambers 18 (and/or the first/left and second/right bale-forming areas), respectively, and to singulate such bales in a manner that allows the bales to be aligned in a single row.
Certain embodiments of the high capacity baler 10, may be configured to obtain data and information related to the baler 10 and/or the bale forming process and to present such information to an operator of the baler 10 so that the operator can monitor and control the bale forming process. In more detail, the embodiments of the present invention may include a control system 300, as illustrated in
The processing element 302 may comprise processors, microprocessors (single-core and multi-core), microcontrollers, DSPs, field-programmable gate arrays (FPGAs), analog and/or digital application-specific integrated circuits (ASICs), or the like, or combinations thereof. The processing element 302 may generally execute, process, or run instructions, code, code segments, software, firmware, programs, applications, apps, processes, services, daemons, or the like. The processing element 302 may also include hardware components such as finite-state machines, sequential and combinational logic, and other electronic circuits that can perform the functions necessary for the operation of the present invention. The processing element 302 may be in communication with other electronic components through serial or parallel links that include address busses, data busses, control lines, and the like.
The memory element 304 may comprise data storage components, such as read-only memory (ROM), programmable ROM, erasable programmable ROM, random-access memory (RAM) such as static RAM (SRAM) or dynamic RAM (DRAM), cache memory, hard disks, floppy disks, optical disks, flash memory, thumb drives, universal serial bus (USB) drives, or the like, or combinations thereof. In some embodiments, the memory element 304 may be embedded in, or packaged in the same package as, the processing element 302. The memory element 304 may include, or may constitute, a non-transitory “computer-readable medium”. The memory element 304 may store the instructions, code, code segments, software, firmware, programs, applications, apps, services, daemons, or the like that are executed by the processing element 302. In particular, the memory element 304 may store information about particular configurations of the control system 300 and/or of the baler 10. The memory element 304 may also be able to store all the information gathered by the various sensors 305, 306, 308.
In more detail, the control system 300 may also include the various sensors (e.g., baler sensors 305, first baling chamber sensors 306, and second baling chamber sensors 308) for obtaining data and information related to the baler 10 and/or to the baling process. The baler sensors 305 may be configured to obtain data and/or various parameters related to the operation of the baler 10, while the baling chamber sensors 306, 308 may be configured to obtain data and/or various parameters related to the baling chambers 18 and/or to the individual bales being formed within the baling chambers 18. Such sensors may provide the obtained data to the processing elements 302 and/or the memory elements 304 for processing and analysis. The resulting processed and/or analyzed data may comprise parameters that can be interpreted by the operator of the baler 10. As such, the data and/or the parameters may be provided to an electronic display 310 in the form of parameters for presentation/display to the operator of the baler 10.
As was discussed previously, each baling chamber 18 of the baler 10 may include one or more bale-forming areas defined therein. In certain embodiments, such as those described in
Embodiments provide for the flake lengths of the individual bales formed in each of the baling chambers 18 to be measured by baling chambers sensors 306, 308, which may comprise various types of flake length sensors. For example, in some embodiments, the flake length sensors may comprise rotation sensors that are positioned on or adjacent to the starwheels 98 positioned on top of the baling chambers 18. As was previously described, the starwheels 98 are configured to contact upper surfaces of the bales and rotate as the bales are formed and travel through the baling chambers 18. Thus, as a charge of crop material is compressed by a plunger 44 into a flake of a bale, the bale is force rearward through the baling chamber 18 a distance generally equal to the width of the flake (i.e., the flake length). The starwheel 98 in engagement with such bale will rotate as the bale is forced rearward, and the magnitude of such rotation will correspond with the flake length of the newly added flake. As such, the flake length sensors associated with the starwheels 98 can measure magnitudes of rotation of the starwheels 98, with such magnitudes corresponding to flake lengths of the bales formed in the left and right baling chambers 18. In addition to sensors that can measure rotation of the starwheels 98, the flake length sensors may alternatively comprise distance sensors (e.g., optical/laser sensors) positioned within the baling chambers 18 and configured to measure individual flake lengths of bales.
In addition to the flake length sensors described above, the baling chamber sensors 306, 308 may comprise other types of sensor configured to measure various parameters of the bales being formed within the baling chambers 18. For example, the baling chamber sensors 306, 308 may comprise flake counting sensors configured to measure the number of flakes included in each bale. Such flake counting sensors may comprise position switches that close each time the plungers 44 cycle to a compression stroke. As noted previously, each time a plunger 44 compresses a charge of crop during the bale forming process, a flake is added to the bale. The flake counting sensors may also incorporate a counter that is configured to count the number of compression strokes, and thus flakes, that are used to form the bale before the bale is tied off by the knotter assembly 90. As a result, the flake counting sensors can be used to determine the number of flakes included within each individual bale formed in the left and right baling chambers 18.
In additional embodiments, the baling chamber sensors 306, 308 may comprise pressure sensors configured to measure the hydraulic pressure being applied to the compression assemblies 60 of the baling chambers 18. The baling chamber sensors 306, 308 may also comprise moisture sensors, perhaps positioned within the baling chambers 18, and configured to measure the moisture content of the crop material being formed into bales within the baling chambers 18. The baling chamber sensors 306, 308 may also comprise weight sensors (i.e., scales), perhaps positioned within the baling chambers 18, and configured to measure the weight of the bales within the baling chambers 18.
In addition to the baling chamber sensors 306, 308, embodiments also provide for the baler 10 to include one or more baler sensors 305 associated with the baler 10 and configured to obtain data and/or parameters related to the baler 10 and/or to the baling process. The baler sensors 305 may comprise a speed sensor positioned on the baler 10 and configured to measure a ground speed of the baler 10. In some embodiments, the speed sensor may be positioned on or otherwise associated with the tractor pulling the baler 10. The baler sensors 305 may also comprise a global positioning system (GPS) sensor positioned on the baler 10 and configured to determine a geolocation of the baler 10. In some embodiments, the GPS sensor may be positioned on or otherwise associated with the tractor pulling the baler 10.
In some embodiments, the baler sensors 305 may also include rotations per minute (RPM) sensors for measuring RPMs of the baler's 10 gearbox 70. The baler sensors 305 may also include a temperature sensor for measuring a temperature within the gearbox 70 (e.g., an oil temperature within the gearbox 70). The baler sensors 305 may also include a brake switch sensor for determining when the brake switch of the baler's 10 flywheel 74 is closed. In embodiments in which the baler 10 includes a hydraulic system, the baler sensors 305 may include oil level sensors for determining whether the hydraulic system has low oil. The baler sensors 305 may also include oil temperature sensors for measuring the oil temperature of the hydraulic system.
Embodiments provide for the control system 300 to obtain data from each of the sensors 305, 306, 308. Such data will generally correspond to parameters of the baler 10, of the baling process, and/or of the bales of crop material. In some embodiments, the data from the sensors 305, 306, 308 may be analyzed by the processor 302 executing one or more computer programs stored on the memory elements 304 to obtain useful parameters. Regardless, the control system 300 will be configured to present such data and/or parameters to an operator of the baler 10 via the electronic display 310. Specifically, the control system 300 may be configured to present a graphical user interface (GUI), as illustrated in
The electronic display 310 may comprise a cathode ray tube, liquid crystal display, plasma, or touchscreen display that is operable to display visual graphics, images, text, etc. In certain embodiments, the computer program of the present invention facilitates interaction and communication through the GUI, as illustrated on
Turning to the GUI in more detail, as illustrated in
The GUI of the electronic display 310 may also include a display area 326 that presents one or more notifications (e.g., icons, graphical elements, etc.) related to real-time operation of the baler 10. The notifications may be alerts that indicate when certain parameters of the baler 10, the baling process, and/or the bales are outside of a desired range. For example, an alert may be provided if bale moisture is too high or low, if bale weight is too high or low, if the baler 10 speed is too high or low, if a length of bales being formed in the left side baling chamber is too long or short, or if a length of bales being formed in the left side baling chamber is too long or short. In some embodiments, the desired range (i.e., a target range) of the parameters may be input by the operator. For instance, the electronic display 310 may be a touchscreen, which allows the operator to input a desired range for one or more of the parameters directly by touching the electronic display 310. As an example, the operator may input a desired length of the bales being formed in the left and right baling chambers 18. If the baling chambers sensors 306, 308 sense that one or more bales formed in the left or right baling chambers 18 are longer or shorter than the desired length, then an alert may be shown on the display area 326. In some embodiments, such an alert, which is a visible alert, may be accompanied by an audible alert produced by a speaker associated with the control system 300.
Moving to a bottom of the GUI, display area 328 may present an icon, graphic element, and/or numerical values illustrative of a length of the last formed bale within the left-side baling chamber 18. The display area 328 may also present an icon, graphic element, and/or numerical values illustrative of the number of flakes included within the last formed bale from the left-side baling chamber 18. The display area 328 alternatively present an icon, graphic element, and/or numerical values illustrative of the total length and/or the number of flakes included within the bale currently being formed the left-side baling chamber 18. Display area 330 may present an icon, graphic element, and/or numerical values illustrative of a length of the last formed bale within the right-side baling chamber 18. The display area 330 may also present an icon, graphic element, and/or numerical values illustrative of the number of flakes included within the last formed bale from the right-side baling chamber 18. The display area 330 alternatively present an icon, graphic element, and/or numerical values illustrative of the total length and/or the number of flakes included within the bale currently being formed the right-side baling chamber 18. Furthermore, display area 332 may present an icon, graphic element, and/or numerical values illustrative of the total number of bales formed by baler 10 during the current job. Such total number may be determined by one or more baling chamber sensors 306, 308 configured to determine when a knotter assembly 90 has tied off a bale, therefore being indicative of a bale having been completely formed by the baler 10. The total number may be alternatively determined by one or more baling chamber sensors 306, 308 (e.g., counters, switches, etc.) configured to count each bale that exits the baling chambers 18.
A center portion of the GUI may include a display area 334 that comprises a pair of graphical vertical bar indicators. A first vertical bar indicator (e.g., a left vertical bar indicator) may correspond with the left side baling chamber 18 (and/or the left side bale-forming area), and a second vertical bar indicator (e.g., a right vertical bar) may correspond with the right side baling chamber 18 (and/or the right side bale-forming area). In embodiments in which the baler 10 includes more than two bale-forming areas (e.g., more than two baling chambers 18), the display area 334 may have more than two vertical bar indicators. Specifically, the number of vertical bar indicators may correspond with the number of baling chambers 18 (and/or the number of bale-forming areas) associated with the baler 10. The vertical bar indicators may be referred to as “flake length bars” and may be used to illustrate the real-time flake lengths of the bales being formed in each of the bale-forming areas (e.g., in the left and right side baling chambers 18). Thus, the flake length bars may also be used to illustrate a real-time comparison between the flake lengths of the bales being formed in each of the bale-forming areas (e.g., in the left and right side baling chambers 18). Furthermore, the flake length bars may be alternatively used to illustrate real-time total lengths of each the bales being formed in the bale-forming areas (e.g., in the left and right side baling chambers 18).
In more detail, as noted above, certain the baling chamber sensors 306, 308 may be configured to measure a flake length of each of the flakes included in the bales being formed in the baling chambers 18. Such baling chamber sensors 306, 308 may send flake length information to the control system 300, which may display such information on the electronic display 310 via the flake length bars presented on the GUI. In certain embodiments, the operator of the baler may set a target flake length via the electronic display 310. For example, the operator may intend for the flake lengths of the bales to have a preferred target of “2.4” inches (such that a “36” inch bale will include fifteen flakes, each having a generally even width). Once the target flake length is entered, the GUI of the electronic display 310 may present an icon, graphic element, and/or numerical values illustrative of the target flake length in display area 336. In addition, the flake length bars within the display area 334 may have central horizontal marker extending behind or through the flake length bars. This central horizontal marker may represent the target flake length.
In operation of the baler 10, and in particular of forming bales in the left and right side baling chambers 18, the interior space of the flake length bars may be filled (e.g., via solid color or textured pattern fills) from bottom up to represent and/or indicate the real-time flake lengths of the bales being formed in the baling chambers 18. As such, when the flake length bars are empty/unfilled, the flake lengths of the bales are zero and no bales are being formed in the baling chambers 18. When the flake length bars are filled halfway, i.e., up to the central horizontal marker, then the real-time flake lengths of the bales being formed in the baling chambers 18 are at the target flake length (e.g., 2.4 inches). When the flake length bars are fully filled, i.e., up to top of the flake length bars, then the real-time flake lengths of the bales being formed in the baling chambers 18 are at twice the target flake length (e.g., 4.8 inches). If the flake length bars are filled up to a position below the central horizontal marker representing the target flake length (e.g., as illustrated in the right side flake length bar of
As such, the flake length bars provide a visual indication to the operator of the baler 10 as to the real-time flake lengths of the bales being formed in the baling chambers 18. If the real-time flake lengths are less than the target flake length, then the operator can increase the speed of the baler to provide more crop material into the baling chambers 18 to thereby increase the flake lengths of the bales being formed in the baling chambers 18. If the real-time flake lengths are greater than the target flake length, then the operator can decrease the speed of the baler to provide less crop material to the baling chambers 18 to thereby increase the flake lengths of the bales being formed in the baling chambers 18. Furthermore, the flake length bars of the display area 334 of the GUI simultaneously illustrate the real-time flake lengths being formed in both the left side and the right side baling chambers 18. As such, if the real-time flake length of the left side baling chamber 18 is greater than or less than the target flake length, then the operator can maneuver or configure the baler 10 to provide less or more crop material, respectively, to the left side baling chamber 18 to thereby decrease or increase, respectively, the flake lengths of the bale being formed in the left side baling chamber 18. Similarly, if the real-time flake length of the right side baling chamber 18 is greater than or less than the target flake length, then the operator can maneuver or configure the baler 10 to provide less or more crop material, respectively, to the right side baling chamber 18 to thereby decrease or increase, respectively, the flake length of the bale being formed in the right side baling chamber 18.
Below the display area 334 that includes the pair of vertical graphical bar indicators, the GUI may include a horizontal graphical bar indicator in a display area 338. The horizontal graphical bar indicator may be referred to as a “bale offset bar” and may be used to illustrate an real-time offset magnitude between bales being formed in the left side baling chamber 18 and bales being formed in the right side baling chamber 18. As was described previously, in some embodiments, the baler 10 may be configured such that bales are formed and ejected from the left and right side baling chambers 18 at different times (i.e., the bales are ejected from the baling chambers 18 in a staggered manner). For example, a bale may be completely formed in the left side baling chamber 18 and tied off (via the left side knotter assembly 90) approximately twenty seconds before a corresponding bale is completely formed in the right side baling chamber 18 and tied off (via the right side knotter assembly 90). As such, the bale formed in the left side baling chamber 18 may be ejected from the baler earlier than (e.g., approximately tweny seconds earlier than) the bale formed in the right side baling chamber 18. Nevertheless, in some embodiments, the baler 10 may be configured such that the bales are formed and ejected from the left and right side baling chambers 18 at generally the same time. In particular, the bales formed in the left and right side baling chambers 18 may be fully formed and tied off (via the knotter assemblies 90) at generally the same time, such that the bales are ejected from the baling chambers 18 generally simultaneously.
In more detail, as was discussed previously, certain the baling chamber sensors 306, 308 may be associated with the knotter assemblies 90 so as to indicate when the knotter assemblies 90 are activated to tie off bales once the bales have been completely formed within the baling chambers 18. Such baling chamber sensors 306, 308 may send to the control system 300 an indication each time the left side knotter assembly 90 and/or the right side knotter assembly 90 ties off a bale being formed in the left side baling chamber 18 and the right side baling chamber, respectively. The control system 300 may, based on the information received from the baling chamber sensors 306, 308, cause information indicative of the magnitude of offset between bales formed in the left and right side baling chamber 18 to be displayed on the electronic display 310 via the bale offset bar. In certain embodiments, the operator of the baler 10 may set a target offset via the electronic display 310. For example, the operator may intend for the bales formed in each of the left side and right side baling chambers 18 to be formed within and/or ejected simultaneously, in an aligned manner. Alternatively, the operator may intend for the bales formed in each of the left side and right side baling chambers 18 to be formed within and/or ejected in an offset or staggered manner. The target offset may be based on time (e.g., the bales formed in the left side baling chamber 18 should be completely formed and tied off “20” seconds before the bales are completely formed and tied off in the right side baling chamber 18) or on bale length (e.g., the bales formed in the left side baling chamber 18 should be completely formed and tied off when the bales being formed in the right side baling chamber 18 are half way completed). Once the target offset is entered by the operator, the GUI of the electronic display 310 may present an icon, graphic element, and/or numerical values illustrative of the target offset in display area 340. For example, as shown in the GUI of
In operation of the baler 10, and in particular during the forming of bales in the left and right side baling chambers 18, an indicator icon (e.g., small white rectangle) may travel left and right through the bale offset bar to indicate the real time offset magnitude between the bales being formed in the left side baling chamber 18 and the bales being formed in the right side baling chamber 18. If the indicator icon is positioned in the middle of the bale offset bar (e.g., centered on the central vertical marker representing the target offset), then the bales being formed in the baling chambers 18 are being formed in baler 10 in sync with the target offset (i.e., either uniformly or at the selected offset). Thus, the electronic display 310 is configured to present a real-time comparison of the flake length of the bales formed in the left side baling chamber 18 and the flake length of the bales formed in the right side baling chamber 18. Specifically, the electronic display 310, via the bale offset bar shown in display area 338, is configured to display a real-time offset distance between which bales formed in the left side baling chamber 18 is being formed and is completed and bales formed in right side baling chamber 18 is completed.
In more detail, if the target offset has been set by the operator to establish that the bales formed in the left and right side baling chambers 18 should be formed and ejected simultaneously (in an aligned manner), then the indicator icon will be centered on the central vertical marker representing the target offset when the bales currently being formed within the left and right side baling chambers 18 are being formed simultaneously and at the same rate so as to be tied off by the left and right side knotter assemblies 90 at the same time (and further such that the bales will be ejected from the left and right side baling chambers 18 generally at the same time). If the indicator icon shifts to the left of the central vertical marker, such a shifting is an indication that the baler 10 is not forming bales according to the target offset. In particular, the leftward shifting of the indicator icon is indicative of the bale being formed in the left side baling chamber 18 being formed at a slower rate than the bale being formed in the right side baling chamber 18 (as perhaps determined by the baling chamber sensor 306, 308 measuring the times at which the left and right side knotter assemblies 90 perform a tying operation on respective bales). As such, the bale being formed in the right side baling chamber 18 will be finished and ejected from the baler 10 faster than the bale being formed in the left side baling chamber 18. The magnitude of the leftward shifting of the indicator icon is generally proportional to the amount by which the formation of the bale in the left side baling chamber 18 is falling behind the formation of the bale in the right side baling chamber 18. The further left the indicator icon shifts, the further behind the bale in the left side baling chamber 18 is falling behind the formation of the bale in the right side baling chamber 18. To correct such an issue, the operator may maneuver the baler 10 and/or otherwise change the configuration of the baler 10 so as to feed more crop material into the left side baling chamber (or less material into the right side baling chamber 18) such that the bales are being formed in and ejected from the left and right side baling chambers 18 are generally the same time (i.e., in a uniform manner). Thus, the electronic display 310 is configured to provide a real-time graphical comparison of relative crop feed rates to the left and right side baling chambers 18.
Similarly, if the indicator icon shifts to the right of the central vertical bar, such shifting is an indication that the baler 10 is not forming bales according to the target offset. Specifically, the rightward shifting of the indicator icon is indicative of the bale being formed in the right side baling chamber 18 being formed at a slower rate than the bale being formed in the left side baling chamber 18 as perhaps determined by the baling chamber sensor 306, 308 measuring the time at which the left and right side knotter assemblies 90 perform a tying operation on respective bales. As such, the bale being formed in the left side baling chamber 18 will be finished and ejected from the baler 10 before the bale being formed in the right side baling chamber 18. The magnitude of the rightward shifting of the indicator icon is generally proportional to the amount by which the formation of the bale in the right side baling chamber 18 is falling behind the formation of the bale in the left side baling chamber 18. The further right the indicator icon shifts, the further behind the bale in the right side baling chamber 18 is falling behind the formation of the bale in the left side baling chamber 18. To correct such an issue, the operator may maneuver the baler 10 and/or otherwise change the configuration of the baler 10 so as to feed more crop material into the right side baling chamber 18 (or less material into the left side baling chamber 18) such that the bales are being formed in and ejected from the left and right side baling chambers 18 are generally the same time (i.e., in a uniform manner).
As was noted previously, the target offset may also be set by the operator to specify that the bales formed in the left and right side baling chambers 18 are formed and ejected not at the same time, i.e., in an alternating, staggered fashion. In such a configuration, the indicator icon will be centered on the central vertical marker of the bale offset bar when the bales formed in the left side baling chamber 18 are properly offset from the bales formed in the right side baling chamber 18. A leftward shifting of the indicator icon is indicative of the bale formed in the left side baling chamber 18 falling behind the appropriate offset with respect to the bale formed in the right side baling chamber 18. Specifically, the bales formed in the left side baling chamber 18 are being formed at a slower pace than the bales formed in the right side baling chamber 18. Similarly, a rightward shifting of the indicator icon is indicative of the bale formed in the right side baling chamber 18 falling behind the appropriate offset with respect to the bale formed in the left side baling chamber 18. Specifically, the bales formed in the right side baling chamber 18 are being formed at a slower pace than the bales formed in the right side baling chamber 18.
In general, the length of the horizontal bale offset bar may be representative of the length of the bales being formed in the baling chambers 18. For instance, if the bales are formed to a length of “36” inches, the central vertical marker will be positioned at a point indicative of the middle of the bale length (i.e., 18 inches). If the indicator icon shifts to half way between the central vertical marker and the left end of the offset bar, the indicator icon will be at a position indicative of “9” inches from the left side of the bale; thus indicating the bales formed in the left side baling chamber 18 are being formed at a pace that is one quarter bale length slower than the bales formed in the right side baling chamber 18. If the indicator icon shifts fully leftward to the left end of the offset bar, the indicator icon will be at a position indicative of the left side of the bale; thus indicating the bales formed in the left side baling chamber 18 are being formed at a pace that is one half bale length slower than the bales formed in the right side baling chamber 18.Similarly, if the indicator icon shifts to half way between the central vertical marker and the right end of the offset bar, the indicator icon will be at a position indicative of “9” inches from the right side of the bale; thus indicating the bales formed in the right side baling chamber 18 are being formed at a pace that is one quarter bale length slower than the bales formed in the left side baling chamber 18. If the indicator icon shifts fully rightward to the right end of the offset bar, the indicator icon will be at a position indicative of the right side of the bale; thus indicating the bales formed in the right side baling chamber 18 are being formed at a pace that is one half bale length slower than the bales formed in the left side baling chamber 18.
The GUI of the electronic display 310 may also include a display area 342 that presents one or more icons, graphic elements, and/or numerical values relevant to the real-time status/operation of the singulator 220 (or other singulator embodiments of the baler 10). For example, display area 342 may include three rectangles, with two side-by-side rectangles positioned above a third, bottom rectangle. The two side-by-side rectangles may be indicative of whether the landing section 222 (e.g., the left side and/or the right side dump cradles 226, 228) is empty or is supporting a bale thereon. In particular, each of the dump cradles 226, 228 may include a baler sensor 305 configured to determine whether the dump cradle 226, 228 is supporting a bale. In some embodiments, the applicable baler sensors 305 may include the electromechanical switch sensors 229 positioned at the rear ends of the dump cradles 226, 228. Alternatively, the bale sensors 305 may include other types of sensors configured to determine if the dump cradles 226, 228 are supporting a bale, such as switches, weight sensors, etc. Regardless, the bale sensors 305 may send information to the control system 300 indicative of whether the dump cradles 226, 228 are supporting bales. The control system 300 may therefrom, generate a visual indication of whether the dump cradles 226, 228 are supporting bales via the electronic display 310, on particularly within the display area 342. Specifically, if the left side dump cradle 226 is not currently supporting a bale, then left rectangle of the two side-by-side rectangles may be shown as unfilled, blank, or filled with a white color. Alternatively, if the left side dump cradle 226 is currently supporting a bale, then left rectangle of the two side-by-side rectangles may be shown as solidly filled in with a dark color or filled in with a textured pattern. The right rectangle of the two side-by-side rectangles may be similarly used (i.e., by being unfilled or filled) to illustrate whether or not the right side dump cradle 228 is currently supporting a bale. For example, as illustrated in
Beneath each of the rectangles of the two side-by-side rectangles, two elongated linear icons may be provided. One linear icon may be horizontal, while another linear icon may be angled downward. Such linear icons may be used as indications of whether the dump cradles 226, 228 are in the bale-receiving position or the bale-dumping position. In some embodiments, the baler sensors 305 may include sensors associated with the hydraulic cylinders that actuate the dump cradles 226, 228. Alternatively, the bale sensors 305 may include other types of sensors configured to determine if the dump cradles 226, 228 are in the bale-receiving positions or the bale-dumping positions. Regardless, the bale sensors 305 may send information to the control system 300 indicative of whether the dump cradles 226, 228 are in the bale-receiving position or the bale-dumping position. The control system 300 may therefrom, generate a visual indication of whether the dump cradles 226, 228 are in the bale-receiving position or the bale-dumping position on the electronic display 310 via the display area 342. Specifically, if the left side dump cradle 226 is in the bale-receiving position, the horizontal linear icon below the left rectangle of the two side-by-side rectangles may be highlighted and the downwardly angled icon may not be highlighted. If the left side dump cradle 226 is in the bale-dumping position, the horizontal linear icon below the left rectangle of the two side-by-side rectangles may not be highlighted and the downwardly angled icon may be highlighted. A similar configuration of the linear icons below the right rectangle of the two side-by-side rectangles may be used to illustrate whether the right side dump cradle 228 is in the bale-receiving position or the bale-dumping position. As illustrated in
The third, bottom rectangle from the display area 342 may be used to represent whether or not a bale is currently being supported on the exit section 224 (e.g., on the receiving tray 230). In particular, the receiving tray 230 may include one or more baler sensors 305 configured to determine whether the receiving tray 230 is currently supporting a bale. In some embodiments, the baler sensors 305 may include the button switches 236 positioned on the receiving tray 230. Alternatively, the baler sensors 305 may include other types of sensors configured to determine if the receiving tray 230 is supporting a bale, such as switches, weight sensors, etc. Regardless, the baler sensors 305 may send information to the control system 300 indicative of whether receiving tray 230 is currently supporting a bale. The control system 300 may therefrom, generate a visual indication of whether the receiving tray 230 is supporting a bale via the electronic display 310, and particularly on the display area 342 of the GUI. Specifically, if the receiving tray 230 is not currently supporting a bale, then the third, bottom rectangle may be shown as unfilled, blank, or filled with a white color. Alternatively, if the receiving tray 230 is currently supporting a bale, then third, bottom rectangle is shown as solidly filled-in with a solid color or filled in with textured pattern. For instance, the third, bottom rectangle shown in display area 342 of the GUI of
Below the three rectangles that indicate whether or not bales are being supported by the dump cradles 226, 228 and/or the receiving tray 230, the display area 342 may include one or more icons indicative of operation of the conveyor 232 associated with the receiving tray 230. In particular, the baler 10 may include one or more baler sensors 305 that are configured to sense whether the conveyor 232 is activated and/or to sense the operating power/speed of the conveyor 232. Such a baler sensors 305 may be associated with a motor that drives the conveyor 232; although, other sensors capable of determining the activation and/or power/speed of the conveyor 232 may be used. Such sensor 305 may provide information to the control system 300, which in turn generates a visual indication of the real-time operation of the conveyor 232 via the GUI on the display screen 310. For example, an arrow icon may be positioned adjacent to an icon representing the conveyor 232. The arrow icon may be presented for display on the GUI whenever the conveyor 232 is activated or running (i.e., so as to push a bale rearward along the receiving tray 230). The display area 342 may also include numerical or graphical indicators indicative of the power or speed at which the conveyor 232 is currently operating. For example, as shown in the GUI of
In some embodiments of the baler 10 that include an accumulator system and/or a bundler system for accumulating/bundling individual bales formed by the baler 10 and pushed out from each of the left and right side baling chambers 18, the electronic display 310 may present information indicative of the real-time status of such accumulator system and/or a bundler system. For example, similar to how the display area 342 illustrates where bales are positioned with respect to the singulator 220, the GUI presented on the electronic display 310 may present icons, graphic elements, and/or other information illustrative of where bales are positioned with respect to the accumulator system and/or a bundler system.
The right side of the GUI of the electronic display 310, as illustrated in
Soft key icon 346 includes an image or graphic depiction of a question mark and may be selected to display a help screen that provides information to an operator of the baler 10 as to how to properly interact with the baler 10, the control system 300, and/or the display screen 310. Soft key icons 348 include images or graphic depictions indicative of a hydraulic pressure increases and decrease. A user may depress one of the soft key icons 348 to selectively increase or decrease the hydraulic tension pressure and/or a target hydraulic tension pressure within the compression assemblies 60. Soft key icons 350 include an image or graphic depiction of one or more bales, and may be selected to display a bale counter screen, which may provide bale processing information (e.g., the number of bales formed during current operating period). Soft key icon 352 includes an image or graphic depiction of an exclamation point within a triangle, and may be selected to display an alarm screen that provides current alarm or alert information to an operator of the baler 10. Soft key icon 354 includes an image or graphic depiction of a wrench, and may be selected to display a diagnostic screen that provides current, real-time diagnostic information to an operator of the baler 10. Soft key icon 354 includes an image or graphic depiction of a gear/sprocket, and may be selected to display a settings screen that provides current, real-time settings information to an operator of the baler 10.
