The disclosure generally relates to a baler implement with an integrated wrap system
Baler implements gather cut crop material and form the crop material into a bale. Generally, the bales may include either round cylindrical shape or a parallelepiped shape, e.g., a rectangular shape. The size of the bales may also vary. For example, the dimensions of a large parallelepiped shaped bale, commonly referred to as a “large square bale” may include end face dimensions between, for example, 3 and 5 feet (i.e., approximately 1.0 and 1.6 meters), and length dimensions between, for example, 4 and 9 feet (i.e., approximately 1.3 and 3.0 meters). In certain circumstances, it is desirable to wrap the bale in a wrap material. For example, in some circumstances, the bale may be completely wrapped in a plastic sheet.
Traditionally, operators wishing to wrap large square bales have formed the bales in the baler implement, bound the formed bales inside the baler implement, and then dropped the formed bales on the ground. After the formed bales have been deposited on the ground, a tractor pulling a separate wrapping implement picks up the large square bale and wraps the large square bale with plastic wrap material. This is an additional step which adds to the time to complete the bale. Additionally, traditional wrapping implements typically rotate or tumble the bale in three dimensions to ensure that all portions of the bale faces are completely covered. Therefore, traditional square bale wrapping implements have practical limits on the length of the large square bales that may be processed reliably. Generally, in some background prior art, these types of wrapping implements are limited to large square bales having a maximum size or maximum length, for example, approximately 5 feet (i.e., approximately 1.6 meters).
A crop baler implement is provided. The crop baler implement includes a frame extending along a longitudinal frame axis. A baling chamber is attached to the frame. The baling chamber is sized to form crop material into a bale having a parallelepiped shape extending along a central longitudinal bale axis and having a transverse bale axis that is perpendicular to the central longitudinal bale axis. A carriage is coupled to the frame rearward of the baling chamber. The carriage includes a tray positioned to receive the bale from the baling chamber in a first orientation. The tray is rotatable relative to the carriage about a substantially vertical tray axis to move the bale from the first orientation to a second orientation. When the bale is disposed in the first orientation, the bale is positioned such that the central longitudinal bale axis is generally parallel with the longitudinal frame axis. When the bale is disposed in the second orientation, the bale is positioned such that the transverse bale axis is generally parallel with the longitudinal frame axis.
In one aspect of the disclosure, an actuator may interconnect the tray and the carriage. The actuator is operable to rotate the tray about the vertical tray axis relative to the carriage. The actuator may include, but is not limited to, an electric motor, a hydraulic motor, a gear train driven by a rotational input, etc.
In one aspect of the disclosure, a transverse wrapping assembly is attached to the carriage. The transverse wrapping assembly is moveable along a path surrounding the tray. The transverse wrapping assembly includes transverse face wrap roller moveable in an endless loop encircling the tray when the bale is disposed in the second orientation. The transverse wrapping assembly may wrap the end faces of the bale.
In another aspect of the disclosure, a longitudinal wrapping assembly is coupled to the frame, between the tray and the baling chamber. The longitudinal wrapping assembly includes longitudinal face wrap roller that is moveable in an endless loop encircling the bale when the bale is disposed in the first orientation. The longitudinal wrapping assembly may wrap the longitudinal faces of the bale. When combined with the transverse wrapping assembly, all faces of the parallelepiped shape bale may be wrapped with the wrapping material.
In one aspect of the disclosure, the bale includes a left side face, a right side face, a top face, a bottom face, a forward end face, and a rearward end face. Each of the left side face, the right side face, the top face, and the bottom face are disposed substantially parallel with the central longitudinal bale axis. Each of the forward end face and the rearward end face are disposed substantially parallel to the transverse bale axis. The longitudinal face wrap roller is operable to hold a roll of wrap material and wrap the left side face, the right side face, the top face, and the bottom face of the bale with the wrap material as the longitudinal face wrap roller moves in the endless loop around the bale. The transverse face wrap roller is operable to hold a roll of wrap material and wrap the forward end face and the rearward end face of the bale with the wrap material as the transverse face wrap roller moves around the tray.
In one aspect of the disclosure, the tray includes a central portion concentrically located about the vertical tray axis. The central portion may include a plurality of omni-direction rollers operable to guide the bale along both a first path and a second path. The second path may be disposed perpendicular to the first path.
In one aspect of the disclosure, the central portion defines a square shape. The tray may include a first wing portion and a second wing portion extending from and coplanar with the central portion. The first wing portion and the second wing portion are disposed opposite each other, and may cooperate with the central portion to define the first path. The tray may further include a third wing portion and a fourth wing portion extending from and coplanar with the central portion. The third wing portion and the fourth wing portion may be disposed opposite each other and may cooperate with the central portion to define the second path.
In one aspect of the disclosure, the carriage includes an arm supporting the transverse face wrap roller. The arm is rotatably attached to the carriage for rotation about the vertical tray axis. The arm moves independent of and relative to the tray about the vertical tray axis. The carriage may further include a rotational drive interconnecting the arm and the carriage. The rotational drive is operable to move the arm about the vertical tray axis relative to the carriage. The rotational drive may include, but is not limited to, an electric motor, a hydraulic motor, a gear train driven by a rotational input, etc.
A method of baling crop material is also provided. The method includes forming a bale within a baling chamber of a baler implement. The bale is formed to include a parallelepiped shape having a left side face, a right side face, a top face, a bottom face, a forward end face, and a rearward end face. Each of the left side face, the right side face, the top face, and the bottom face are disposed substantially parallel with a central longitudinal bale axis. Each of the forward end face and the rearward end face are disposed substantially transverse to the central longitudinal bale axis, and parallel with a transverse bale axis. The longitudinal faces of the bale, i.e., the left side face, the right side face, the top face, and the bottom face may then be wrapped with a wrap material from a roll of wrap material supported on a longitudinal face wrap roller. The longitudinal faces of the bale may be wrapped by the longitudinal face wrap roller as the bale is discharged from the baling chamber and while the bale is disposed in a first orientation. The bale may then be conveyed along a longitudinal frame axis of the baler implement onto a tray, whereby the bale is disposed in the first orientation on the tray. When disposed in the first orientation, the central longitudinal bale axis of the bale is substantially parallel with the longitudinal frame axis. The tray with the bale disposed thereon may then be rotated to present the bale in a second orientation. When disposed in the second orientation, the central longitudinal bale axis of the bale is substantially perpendicular with the longitudinal frame axis, and a transverse axis of the bale is substantially parallel with the longitudinal frame axis. When the bale is disposed in the second orientation, the transverse faces of the bale, i.e., the forward end face and the rearward end face, may then be wrapped with a wrap material from a roll of wrap material supported on a transverse face wrap roller. After the transverse faces of the bale have been wrapped, the bale may be discharged from the tray and onto a ground surface from the second orientation.
In one aspect of the disclosure, discharging the bale from the tray and onto the ground surface may include forming a second bale within the baling chamber, and pushing the bale, which is disposed in the second orientation, off of the tray with the second bale as the second bale is conveyed onto the tray in the first orientation.
In another aspect of the disclosure, the tray includes an arm supporting the transverse face wrap roller. The arm is rotatable relative to and independent of the tray. The step of wrapping the transverse faces of the bale with the wrap material, i.e., the forward end face and the rearward end face, may include rotating the arm about a vertical tray axis relative to the tray to move the transverse face wrap roller about the tray and the bale.
Accordingly, the baler implement described herein both forms the bale and wraps the bale with the wrap material. The longitudinal face wrap roller wraps the longitudinal faces of the bale, i.e., the left side face, the right side face, the top face, and the bottom face, as the bale is discharged from the baling chamber and disposed in the first orientation in which the central longitudinal bale axis is parallel with the longitudinal frame axis. The tray may then be rotated about het vertical tray axis to move the bale into the second orientation, in which the central longitudinal bale is perpendicular with the longitudinal frame axis. When the bale is disposed in the second orientation, the transverse face wrap roller moves around the tray and the bale to wrap the forward end face and the rearward end face in the wrap material, thereby completely enclosing the bale in the wrap material. This enables the baler implement to wrap large square bales having a length greater than 5 feet long (i.e., approximately 1.6 meters).
The above features and advantages and other features and advantages of the present teachings are readily apparent from the following detailed description of the best modes for carrying out the teachings when taken in connection with the accompanying drawings.

Referring to the Figures, wherein like numerals indicate like parts throughout the several views, a crop baler implement is generally shown at 20. The crop baler implement 20 shown in the Figures and described herein is embodied as a large square baler. However, it should be appreciated that that the teachings of this disclosure may be applied to other types and configurations of the crop baler implement 20.
Referring to
The crop baler implement 20 gathers cut crop material and moves the crop material into the baling chamber 28 with a feed system (not shown). The baling chamber 28 is attached to the frame 22 and includes walls sized to form crop material into a bale 30. A plunger (not shown) compresses the crop material into a flake. The process is repeated with each flake adding to a length 32 of the bale 30. When the bale 30 reaches a desired length 32, measured along a central longitudinal bale axis 34 of the bale 30, a knotter system (not shown) ties a twine, cord, binding material, or other suitable wrapping material around the bale 30 to secure the flakes together and form the bale 30. The baling chamber 28 forms the bale 30 to have a parallelepiped shape extending along the central longitudinal bale axis 34 and having a transverse bale axis 36 perpendicular to the central longitudinal bale axis 34. The parallelepiped shape of the bale 30 is commonly referred to as a rectangular bale 30, a square bale 30, or a large square bale 30.
Typically, referring to
As shown in
Certain crops and/or crops having a certain moisture content, e.g., silage, may need to be wrapped with a wrap material 54, such as but not limited to a solid plastic wrap, to completely enclose the bale 30 in a substantially air tight wrapping. In other embodiments, the bales 30 may be wrapped with twine, cord, binding material, a water permeable material, a water semi-permeable material, a non-solid net-type material, etc., to allow the harvested crop to breath or dry to a desired moisture level and to inhibit mold formation. In order to wrap the bales 30 with the wrap material 54, the crop baler implement 20 is equipped with a wrap system. Referring to
Referring to
The fixed support 60 rotatably supports an orbital support 64. The orbital support 64 is rotatable about a wrap axis 66, and is moveable about the wrap axis 66 relative to the fixed support 60. The orbital support 64 defines an open central region and is positioned to receive the bale 30 in the first orientation from the baling chamber 28 and pass the bale 30 through the open central region of the orbital support 64. The orbital support 64 may include an annular or circular shape that encircles the bale 30 as the bale 30 is discharged from the baling chamber 28, on the bale chute 62.
The longitudinal wrapping assembly further includes a plurality of rollers 68 interconnecting the orbital support 64 and the fixed support 60. The rollers 68 allow rotation of the orbital support 64 relative to the fixed support 60. As such, the shape of the fixed support 60 generally defines an endless loop or iterative rotations forming a circular path that the orbital support 64 follows, as the orbital support 64 moves about the wrap axis 66 relative to the fixed support 60.
At least one longitudinal face wrap roller 70 is attached to and moveable with the orbital support 64. The longitudinal face wrap roller 70 is moveable in the endless loop along the circular path encircling the bale 30 as the bale 30 is ejected from the baling chamber 28 and moved down the bale chute 62 in the first orientation. The longitudinal face wrap roller 70 is operable to hold a roll of wrap material 54 and dispense the wrap material 54 to wrap the longitudinal faces of the bale 30 with the wrap material 54, i.e., the left side face 42, the right side face 44, the top face 46, and the bottom face 48, as the longitudinal face wrap roller 70 moves in the endless loop along the circular path and around the bale 30.
A drive 72 is coupled to the orbital support 64. The drive 72 is operable to rotate the orbital support 64 and the wrap roller about the wrap axis 66 to wrap the wrap material 54 around the bale 30 as the bale 30 moves through the open central region of the orbital support 64. The drive 72 may include any device and/or system capable of rotating the orbital support 64 relative to the fixed support 60. In the example embodiment shown in the Figures and described herein, the drive 72 includes a motor, for example an electric motor, hydraulic motor or other rotational energy source, that rotates a wheel. Frictional engagement between the wheel and the orbital support 64 causes the orbital support 64 to rotate about the wrap axis 66 relative to the fixed support 60. The motor may include, but is not limited to, an electric motor, a hydraulic motor, or some other type of device capable of rotating the wheel. It should be appreciated that the drive 72 may include some other device not described or shown herein that is capable of rotating the orbital support 64 relative to the fixed support 60.
The longitudinal face wrap roller 70 may further include a wrap cutter 74 attached to and moveable with the orbital support 64. The wrap cutter 74 is disposed adjacent to the longitudinal face wrap roller 70, and is operable to secure and cut the wrap material 54 dispensed from the longitudinal face wrap roller 70.
Referring to
In the example implementation of the baler implement 20 described herein, the transverse wrapping assembly is attached to and supported on a carriage 76. The carriage 76 is coupled to the frame 22 rearward of the baling chamber 28. More particularly, in the example implementation, the transverse wrapping assembly is disposed rearward of the longitudinal wrapping assembly relative to a direction of travel of the baler implement 20. As such, the longitudinal wrapping assembly is positioned between the baling chamber 28 and the carriage 76.
Referring to
The tray 78 is rotatable relative to the carriage 76 about a substantially vertical tray axis 80. As such, the tray 78 rotates on a substantially horizontal plane. The tray 78 is rotatable to move the bale 30 from the first orientation to a second orientation. The second orientation is generally defined as a position of the bale 30 rotated approximately ninety degrees (90°) from the first orientation on a horizontal plane, or such that the transverse bale axis 36 is generally parallel with the longitudinal frame axis 24 and the central longitudinal bale axis 34 is substantially perpendicular or transverse to the longitudinal frame axis 24.
The carriage 76 may include an actuator 82 that rotatably interconnects the tray 78 and the carriage 76. The actuator 82 is operable to rotate the tray 78 about the vertical tray axis 80 relative to the carriage 76. The actuator 82 may include, but is not limited to, an electric motor, a hydraulic motor, a pneumatic drive, etc. Additionally, it should be appreciated that the actuator 82 may include all gears, bearings, races, shafts, etc. necessary to rotatably support and rotate the tray 78 relative to the carriage 76. The specific configuration and operation of the actuator 82 and the components thereof are not pertinent to the teachings of the disclosure, are understood by those skilled in the art, and are therefore not described in detail herein.
The transverse wrapping assembly is rotatably attached to the carriage 76 and moveable along a path surrounding the tray 78. The transverse wrapping assembly includes an arm 84 that is rotatably attached to the carriage 76 for rotation about the vertical tray axis 80. A rotational drive 86 may rotatably interconnect the arm 84 and the carriage 76. The rotational drive 86 is operable to move the arm 84 about the vertical tray axis 80 relative to the carriage 76. For each bale 30 wrapped by the transverse wrapping assembly, the tray 78 may rotate approximately ninety degrees about the vertical tray axis 80 to move the bale 30 from the first orientation to the second orientation, whereas the arm 84 may rotate one or more full rotations about the vertical tray axis 80. As such, the arm 84 moves independent of and relative to the tray 78 about the vertical tray axis 80.
The rotational drive 86 may include, but is not limited to, an electric motor, a hydraulic motor, a pneumatic drive, etc. Additionally, it should be appreciated that the rotational drive 86 may include all gears, bearings, races, shafts, etc. necessary to rotatably support and rotate the arm 84 relative to the carriage 76 and/or the tray 78. In one implementation, the rotational drive 86 and the actuator 82 are separate from each other and operate independently of each other. In other implementations, it is contemplated that the rotational drive 86 and the actuator 82 may be combined into a single manufacture, and selectively controlled to move only the tray 78, only the arm 84, or both the tray 78 and the arm 84 simultaneously. The specific configuration and operation of the rotational drive 86 and the components thereof are not pertinent to the teachings of the disclosure, are understood by those skilled in the art, and are therefore not described in detail herein.
The transverse wrapping assembly includes transverse face wrap roller 88. The transverse face wrap roller 88 is attached to and supported on a distal end of the arm 84. The transverse face wrap roller 88 is moveable in an endless loop encircling the tray 78 about the vertical tray axis 80. The transverse face wrap roller 88 is operable to hold a roll of wrap material 54 and wrap the forward end face 50 and the rearward end face 52 of the bale 30 with the wrap material 54 as the transverse face wrap roller 88 moves around the tray 78. It should be appreciated that in addition to wrapping the forward end face 50 and the rearward end face 52 of the bale 30, the transverse wrapping assembly will further wrap the left side face 42 and the right side face 44 of the bale 30.
The transverse face wrap roller 88 may further include a wrap cutter 74 attached to and moveable with the arm 84. The wrap cutter 74 is disposed adjacent to the transverse face wrap roller 88, and is operable to secure and cut the wrap material 54 dispensed from the transverse face wrap roller 88.
In the implementation of the tray 78 shown in the Figures and described herein, the tray 78 includes a central portion 90 concentrically located about the vertical tray axis 80. In the example implementation, the central portion 90 defines a generally square shape, and includes a plurality of omni-direction rollers 68. The omni-directional rollers 92 are operable to guide the bale 30 along both a first path 94 and a second path 96. The second path 96 is disposed perpendicular to the first path 94.
Referring to
The tray 78 further includes a third wing portion 104 and a fourth wing portion 106. Both the third wing portion 104 and the fourth wing portion 106 extend from a respective side of the square shape of the central portion 90. Additionally, both the third wing portion 104 and the fourth wing portion 106 are coplanar with the central portion 90 of the tray 78. The third wing portion 104 and the fourth wing portion 106 are disposed opposite each other, across the vertical tray axis 80 from each. Each of the third wing portion 104 and the fourth wing portion 106 include at least one respective cylindrical guide roller 102 orientated to guide the bale 30 along the second path 96. The respective cylindrical guide roller 102 of the third wing portion 104 and the fourth wing portion 106 rotate about respective central axes that are perpendicular to the vertical tray axis 80.
In operation, the bale 30 is discharged from the bale chute 62 onto the tray 78 in the first orientation. As shown in
A method of baling crop material is also provided. The method includes forming the bale 30 within the baling chamber 28 of the baler implement 20. As described above, the bale 30 is formed to include the parallelepiped shape having the left side face 42, the right side face 44, the top face 46, the bottom face 48, the forward end face 50, and the rearward end face 52. Once the bale 30 is formed in the baling chamber 28, the bale 30 is bound with tine to secure the flakes of the bale 30 together, after which, the bale 30 is pushed out of the baling chamber 28 and onto the bale chute 62 in the first orientation. As noted above, when disposed in the first orientation, the central longitudinal bale axis 34 is aligned or parallel with the longitudinal frame axis 24 of the baler implement 20.
As the bale 30 is conveyed down the bale chute 62, the longitudinal faces of the bale 30 are wrapped with the longitudinal wrapping system 56. As noted above, the longitudinal faces of the bale 30 include the left side face 42, the right side face 44, the top face 46, and the bottom face 48 of the bale 30. Wrapping the longitudinal faces of the bale 30 includes rotating the orbital support 64 about the wrap axis 66 to unwind the wrap material 54 from the longitudinal face wrap roller 70 onto the bale 30 as the bale 30 moves along the bale chute 62 in the first orientation.
The bale 30 is conveyed on the bale chute 62 along the longitudinal frame axis 24 of the baler implement 20 onto the tray 78, whereby the bale 30 is disposed on the tray 78 in the first orientation. The tray 78 is then rotated approximately ninety degrees (90°) with the bale 30 disposed thereon to present the bale 30 in the second orientation in which the central longitudinal bale axis 34 of the bale 30 is substantially perpendicular with the longitudinal frame axis 24.
After the bale 30 is positioned in the second orientation, the transverse faces of the bale 30 are wrapped with the transverse wrapping system 58. As noted above, the transverse faces of the bale 30 include the forward end face 50 and the rearward end face 52. Wrapping the transverse faces of the bale 30 includes rotating the arm 84 about the vertical tray axis 80 relative to the tray 78 to move the transverse face wrap roller 88 around the bale 30 and unwind the wrap material 54 from the transverse face wrap roller 88 onto the bale 30. It should be appreciated that rotating the bale 30 from the first orientation to the second orientation allows the transverse face wrap roller 88 to move between the bale 30 and the bale chute 62, thereby enabling the transverse wrapping system 58 to rotate around the bale 30 without interference.
After the transverse faces of the bale 30 have been wrapped, and with the bale 30 in the second orientation, the bale 30 may then be discharged from the tray 78 and onto the ground surface 110. A subsequent or second bale 108 may be used to discharge the bale 30 from the tray 78, when the bale 30 is disposed in the second orientation. The second bale 108 is formed in the baling chamber 28, bound with the tine, and conveyed along the bale chute 62 in the first orientation during which the longitudinal faces of the second bale 108 are wrapped with the longitudinal wrapping system 56 as described above. As the second bale 108 is conveyed onto the tray 78 in the first orientation, the second bale 108 pushes the initial bale 30, which is disposed in the second orientation, off of the rearward edge of the tray 78 and onto the ground surface 110.
The detailed description and the drawings or figures are supportive and descriptive of the disclosure, but the scope of the disclosure is defined solely by the claims. While some of the best modes and other embodiments for carrying out the claimed teachings have been described in detail, various alternative designs and embodiments exist for practicing the disclosure defined in the appended claims.
