Description

FIELD OF THE DISCLOSURE

The field of this disclosure relates to apparatus and methods for gathering bales and, in particular, round bales such as hay or corn stover bales.

BACKGROUND

Crop forages such as hay (e.g., alfalfa and/or grass hay) are periodically cut in the field, dried and compacted into bales for transport and storage of the forage material. Recent evolutions in row crop production and in technology for processing these materials have led to changes in the scale and economics of harvest and to increasing potential for harvest of crop residues like corn stover. Corn stover is also baled in the field and used as livestock feed, bedding or production of biofuels. In addition, harvest technology for cotton has been developed, that includes the step of baling the cotton in the field. Due to these relatively recent changes, the scale at which this type of harvest process is conducted in some instances is different than the traditional process. The density of the bales, in terms of the number of bales per acre, is higher in some instances, the labor availability is less in some instances and the criticality of timing is higher in some instances.

Materials may be baled into relatively large round (round in cross-section) bales which may be tied by twine, netting or plastic wrap depending on the type of material, the type of storage and the intended use of the material. The bales are typically left in the field, near the location where the bale was formed, to minimize labor and time required for the harvest process including the baling operation.

A continuing need exists for an apparatus for gathering and transporting round bales in the field after baling, one that allows the bales to be gathered relatively quickly and reliably and in a way to minimize demands on the operator, and that consistently positions the bales adjacent one another to minimize the area required for storage. A need also exists for methods for gathering bales that use such apparatus.

This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure.

DETAILED DESCRIPTION

An embodiment of an apparatus for gathering round bales is generally referred to as 5 in FIG. 1. The apparatus 5 includes a bed 25 for holding one or more bales and a loading assembly 15 for lifting a bale of the ground and conveying it to the bed. The apparatus 5 includes a tongue 1 for pulling the apparatus by use for example, a tractor or other pulling vehicle. In some embodiments (not shown) the apparatus 5 includes its own propulsion mechanism rather than being pulled by a pulling vehicle.

The apparatus 5 includes wheels 3. The wheels 3 on each side of the apparatus 5 are attached to a tandem axle 19 by use of hub and spindle assemblies (not shown). The tandem axles 19 are connected by a frame which is pivotally connected to the bed chassis 6. This arrangement allows the bed 25 to be tilted between various positions. The bed may be tilted to a forward position for loading the bales (FIG. 7) or unloading to the front, to a middle position used after bales have been loaded for transportation of the loaded bales (FIG. 9) or to a rearward tilted position for unloading and re-loading of bales to the rear (FIG. 10). The apparatus 5 may be tilted hydraulically through manual or automatic control by use of a hydraulic cylinder 17 (FIG. 2) or by any other method available to those of skill in the art. Tracks (not shown) may be used as an alternative to the wheels 3.

The loading assembly 15 includes two arms 4, 24 that are the first portion of the apparatus 5 to contact the bale during loading. Each arm 4, 24 includes an endless conveyor belt 16, 18. Referring now to FIGS. 8-11 in which one arm 4 is shown in detail, the endless conveyor belt 16 moves along a path between a front idler roller 162i (FIG. 12) that rotates freely and a driven rear roller 162 (FIG. 14) connected to a rotary power device such as a hydraulic motor described below. The arm 4 includes support rollers 165 (FIG. 13) positioned between the front idler roller and the drive roller.

Each belt 16, 18 includes upper portions 16u, 18u (FIG. 1) that are capable of carrying the weight of a bale. The effective length of these conveyors is approximately the length of this upper surface, or the distance between the front idler roller 162i (FIG. 12) and the rear drive roller 162 (FIG. 14). The movement of the belt, around the front idler roller 162i and backward along the upper portion of the belt path, has been found to be effective to lift a bale off the ground and for simultaneously causing the bale to move toward the bed 25. This lifting and transporting action occurs after the two conveyor belts contact the bale B1 (FIG. 7).

The portion of the belt 16, 18 (FIG. 3) that initially contacts the bale may be referred to herein as the “bale-engaging face” 20, 22. Each bale engaging face 20, 22 of the arms 4, 24 of the apparatus 5 includes a generally planar surface with an effective length equal to the distance between the front idler roller and rear drive roller, and a width equal to the width of the conveyor belt. The axis of rotation of the idler roller and drive roller and any intermediate support rollers are generally parallel. The axes of rotation of these rollers determines the vertical axes of the bale-engaging faces 20, 22. The vertical axis Y₁ of the bale-engaging face 20 forms an angle θ₁ with the surface on which the bale rests, the ground (i.e., is not parallel or perpendicular to the ground surface). The vertical axis Y₂ of the bale-engaging face (not shown) of the second arm similarly forms an angle θ₂ with the surface on which the bale rests. In this regard, it should be noted that the surface on which the bale rests may be curved. In such embodiments, θ should be determined with reference to a flat horizontal surface.

Angles θ₁ and θ₂ may be selected such that the bale-engaging faces 20, 22 match the contour of the bales being loaded. For example, if it is desired to contact the bale at its 4:30 and 7:30 positions, the vertical axis Y₁ and Y₂ may form an angle of about 45° with the ground-surface. If it is desired to contact the bale at its 5:00 and 7:00 positions, the vertical axis Y₁ and Y₂ may form an angle of about 30° with the ground-surface. It should be noted that, for a set spacing between arms, the angular position of the bale at which the bale-engaging faces 20, 22 contact the bale may vary with varying bale diameters. In some embodiments of the present disclosure, the spacing between arms is adjustable to account for changes in bale and/or baler sizes.

In various embodiments, both θ₁ and θ₂ may be between about 10° and about 80° or from about 20° to about 70°, from about 30° to about 60°, from about 40° to about 50° or at about 45°.

Referring now to FIG. 4, the bed 25 has a first end 27 and a second end 32 and has a lengthwise axis A that extends through the first and second ends of the bed. In some embodiments and as shown in FIG. 4, the lengthwise axis X₁ of the first bale-engaging face 20 and the lengthwise axis X₂ of the second bale-engaging face 22 are substantially parallel to the lengthwise axis A of the bed 25.

As shown in FIG. 5, rather than being parallel, the lengthwise axes X₁, X₂ of the bale-engaging faces 20, 22 may form angles β₁, β₂ with the lengthwise axis A of the bed 25. In some embodiments, both β₁ and β₂ are less than about 30° or less than about 20°, less than about 10° or less than about 5° (e.g., from 0° to about 30° or from about 5° to about) 30°.

In some embodiments and as shown in FIG. 6, the first and second conveyor belts 16, 18 may include several angular portions. The leading angular portions of the belts 16, 18 form the bale-engaging faces 20, 22. The bale-engaging faces have lengthwise axis X₁, X₂ which form angles β₁, β₂ with the lengthwise axis A, With β₁ and β₂ being less than about 30° or less than about 20°, less than about 10° or less than about 5° (e.g., from 0° to about 30° or from about 5° to about) 30°. As shown in FIG. 6, the bale-engaging faces 20, 22 may transition to second portions 31, 33 of the conveyor belts that have lengthwise axes that are parallel the lengthwise axis A of the bed 25.

Referring again to FIG. 1, the bed 25 includes a number of bed conveyors 35, each including of an endless belt routed around a front or rear idler roller and a rear or front powered roller that may be rotated to cause the belt to move which results in moving bales away from the loading assembly and toward the end 27 of the bed. Each conveyor 35 may have a length, the distance between the idler roller and the drive roller that is about the length of one bale. Typical bale lengths for forage products are between about forty and sixty inches, but the apparatus should not be limited by bale size; the bed could be constructed to function with bales that are in excess of sixty inches in length (e.g., cotton bales which are in the range of 100 inches in length).

Alternatively, the bed 25 may have one bed conveyor (not shown) on each side that extends from the first end 32 to the second end 27 rather than a series of bed conveyors on each side. In some embodiments, the bed 25 has a single conveyor belt (not shown) that forms a floor of the bed upon which the bales rest for moving bales toward the second end 27.

The conveyor belts 16, 18 of the first and second arms 4, 24 of the loading assembly may be driven by hydraulics, by a power-take-off system or by an electrical drive. Similarly, the bed conveyor belts 35 may be driven by hydraulics, a power-take-off system or an electric drive. The position of the loading assembly 15 and bed 25 relative to the pull vehicle (i.e., whether the apparatus is pulled directly behind the pull vehicle or at an offset position such as when bales are being gathered from the field) may be adjusted by manipulating the angle between the tongue 1 and the chassis 6 (FIG. 7) by use of hydraulics or by any other method suitable to those of skill in the art.

The bed conveyors 35 could be constructed from the same basic components used in the loading assembly conveyors, with an endless conveyor belt, an idler roller, a drive roller and supports. The embodiments illustrated herein show an alternative construction for the bed conveyors 35, each including an endless conveyor belt of a slightly different construction than the belts 16 and 18, routed around a drive pulley 62 and an idler pulley 62i. In some cases the drive pulley 62 is positioned at the front, and in some cases at the rear.

The surface characteristics of the conveyors 16, 18 may affect the frictional engagement between the conveyor belt and the bale. The conveyor belts 16, 18 may include a surface that will adequately engage the bale to enhance the capability for the loading assembly to reliably lift the bales while also minimizing potential for damage to the bale and any bale wrapping.

It should be noted that any suitable type of conveyer belts or conveyor systems may be included in the apparatus. For instance, a conveyor belt composed of a carcass of nylon or fiberglass fibers covered by a wide variety of materials including rubber, PVC, thermoplastic polymer or the equivalent may be used. Chain conveyor systems may also be used without departing from the scope of the present disclosure. In this regard, “conveyor belt” as used herein includes any arrangement in which a belt, chain, track or the like is moved around a series of pulleys to cause movement of the belt, chain or track.

In operation, the apparatus 5 is pulled by the pull vehicle (not shown) toward a bale as shown in FIG. 3. The vehicle may provide the power for running the various conveyors and positioning systems (e.g., by use of hydraulics) or the apparatus 5 may include its own dedicated power system (e.g., hydraulic system). The apparatus described herein uses a hydraulic system, but this disclosure should not be limited to a hydraulic system as the principles would apply to other power transfer technologies such as an electrical system.

Generally, the apparatus 5 is suitable for picking up cylindrical bales commonly referred to as “round” bales. Round bales are used for harvesting any material capable of being formed into a cylindrical bale such as traditional hay crops (e.g., alfalfa or grass), corn stover or other crop residues, cotton, or woody products like small diameter trees. The round bales may have a variety of sizes typically ranging from forty to one hundred inches in diameter and forty to one hundred inches in length. The apparatus 5 shown in FIGS. 1-17 is configured for loading up to 5 bales. The apparatus 5 may be modified to carry more or less bales without departing from the scope of the present disclosure.

As shown in FIG. 7, the bale B1 should be oriented such that the ends 40 of the cylindrical bale are perpendicular to the apparatus 5 as the apparatus 5 approaches the bale B1.

The chassis 6 and tongue 1 are caused to be at an angle λ (FIG. 7) relative to one another such that the loading assembly 15 and bed 25 travel outside of the path of the pull vehicle (not shown) to allow the pull vehicle to travel to the outside of bales targeted for loading.

The first and second conveyor belts 16, 18 are caused to move by rotating the drive rollers while the apparatus 5 travels toward the bale B1. As the apparatus 5 approaches the bale B, the conveyor belts 16, 18 of the arms 4, 24 contact the bale causing the bale to be lifted and simultaneously moved toward the bed 25. The bale B1 may be loaded onto the loading assembly 15 without stopping the apparatus 5 such that the apparatus 5 and the vehicle which pulls the apparatus may continually move forward during bale pick-up.

Once the bale is loaded on the loading assembly 15, belt conveyors 35 (e.g., the set of conveyors nearest the loading assembly) move to transfer the bale B1 from the loading assembly 15 to the position on the bed illustrated in FIG. 8. Once loaded onto the bed 25, the bed conveyors 35 are stopped to position the first bale adjacent the end of the loading assembly.

Once the first bale B is loaded, the apparatus 5 is directed to a second bale. The loading assembly 15 lifts the second bale and carries the second bale toward the bed 25 until it contacts or nears the first bale. Upon contacting or nearing the first bale, one or more sets of bed conveyors 35 are caused to rotate and the first and second bales travel partially down the bed 25 toward the second end 27.

Bales may continue to be loaded onto the apparatus 5 until the apparatus becomes fully loaded. Once fully loaded, the apparatus 5 may be adjusted to promote ease of travel to the unloading site. As shown in FIG. 9, the chassis 6 of the apparatus 5 may be leveled by use of hydraulic cylinder 17 (FIG. 2) and the relative position between the tongue 1 and the bed 15 may be adjusted (e.g., the tongue may be adjusted to be more parallel to the bed).

As shown in FIG. 10, once the apparatus 5 is pulled to the desired unloading site for the bales, the chassis 6 is tilted by use of the hydraulic cylinder 17 (FIG. 2). The bed conveyors 35 are operated and the apparatus 5 is caused to move forward while the bales are unloaded. In some embodiments, the chassis 6 is tilted as when bales are loaded onto the bed (FIG. 7) and the apparatus is caused to move backward with rotation of the bed conveyors 35 such that bales are unloaded to the front.

Compared to conventional apparatus for gathering bales, the apparatus 5 described above has several advantages. In some embodiments, the components of the apparatus that initially contact a bale are moving toward the rear of the device thereby minimizing damage to the bale and any bale-wrapping (i.e., the apparatus does not contain stationary parts which initially contact the bale). By arranging the arms such that the lengthwise axis of the bale-engaging surfaces 20, 22 of each loading arm 4, 24 are parallel to (FIG. 4) or form an angle of less than 30° with the lengthwise axis of the bed (FIGS. 5 and 6), the conveyor belts 16, 18 may be prevented from being bound by the bale as the bale proceeds up the arms 4, 24 and toward the bed 25. Further, by arranging the arms 4, 24 such that the vertical axes Y₁, Y₂ of bale-engaging faces form an angle with the surface on which the bale rests, the bale-engaging faces 20, 22 may complement the contour of the bale at the portion of the bale which contacts the bale-engaging faces 20, 22 which eases the lifting the bale and helps facilitate transfer of bale from the ground to the loading assembly 15. In addition, by using a loading assembly 15 separate from the bed 25, the loading assembly conveyor belts 16, 18 may rotate independent of the conveyor belts 35 of the bed 25, thereby minimizing the amount of rotation of the bed conveyor belts 35 which prevents loaded bale(s) from being damaged.

When introducing elements of the present disclosure or the embodiment(s) thereof, the articles “a”, “an”, “the” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” “containing” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. The use of terms indicating a particular orientation (e.g., “top”, “bottom”, “side”, etc.) is for convenience of description and does not require any particular orientation of the item described.

As various changes could be made in the above constructions and methods without departing from the scope of the disclosure, it is intended that all matter contained in the above description and shown in the accompanying drawing[s] shall be interpreted as illustrative and not in a limiting sense.
