1. Field of the Invention
The present invention relates to handling of bales of bulk material such as hay or silage and includes the pick-up and loading of such bales onto to a vehicle mounted platform or deck with subsequent break-up and discharge of the bulk material for animal feeding. Although not restricted to any particular bale size, the invention is especially pertinent to the handling of extremely large bales of the type described which are too heavy to be handled manually and, in particular, large rectangular cross section hay bales. A generally L-shaped platform includes a bale engaging and lifting frame means for engaging one side of a rectangular bale and a conveyor mechanism for engaging an adjacent side for supporting the bale when moved to the loaded position of the platform and subsequent bale discharge.
2. Description of the Prior Art
In recent years the trend in preserving hay bales has been toward increasingly large size bales, far beyond the ability for manual handling. Although large round bales, several feet in diameter, have been developed and equipment has been designed either to simply unroll the layered bale and/or perform a chopping operation for pasture or range feeding, the results have not been entirely satisfactory. More recently, the trend has been toward the formation of large rectangular or square cross section bales for more ease of transport and stacking. Equipment has been developed such as disclosed in my co-pending U.S. patent application Ser. No. 09/370,359, Vehicle Mounted Large Bale Loading, Transporting And Unloading System, now U.S. Pat. No. 6,328,520 B1, issued Dec. 11, 2001 and Ser. No. 09/721,599, Loading Grapple Table, now U.S. Pat. No. 6,540,464, issued Apr. 1, 2003, for loading, transporting and unloading bales of this type to either form stacks of multiple bales or to transport multiple large bales and to distribute or unload individual bales for pasture, range or bunk feeding. The equipment for accomplishing this task is designed essentially of large capacity and complexity for handling the shear weight and size of the multiple large bales. The need has arisen for single bale pick-up, transport and feeding functions for small farms utilizing smaller sized existing equipment such as tractors, trailers and small trucks.
The present invention contemplates a generally L-shaped platform having an upright bale gripping frame structure and a generally horizontal deck or support surface. The platform engages a square or rectangular cross section bale while in a ground or platform supported position and lifts it to an above-ground elevated position for break-up and dispensing as the vehicle moves. The broken bale material may be deposited on the ground or other surface suitable for feeding animals. The L-shaped platform is adapted to be mounted on a wide variety of transport vehicles such as on a suitable three-point tractor hitch system, either in the front or rear end of Category I, II and III existing tractor hitches; on the rear end of small vehicles such as pick-up trucks, or; on wheeled trailers and the like. The L-shaped frame is carried on the vehicle in a transport position with the gripping frame extending generally vertically and the bale support deck at right angles thereto, extending generally horizontally.
In the preferred embodiment, the gripping frame is equipped with multiple bale engaging grapple hooks or other bale engaging mechanisms for grasping and lifting a bale from the ground and the deck or bale support section is equipped with conveyor means for moving the loaded bale transversely of the platform to dispense the broken bale to one side of the moving vehicle. The platform is pivoted between the transport position and a pick-up position with the gripping frame extending generally horizontally and the grapple means engaging the top and/or sides of the bale. In this position, the conveyor on the support deck engages an adjacent side of the bale. A single bale is thus gripped, pivoted through an approximate 90° angle and transported and unloaded.
In one embodiment, suitable for category I three point hitches of small farm tractors, the pivoting platform may be equipped with ground engaging wheels which pivot with the platform and engage the ground for additional support when the platform is in the transport position. With this modification, small tractors are capable of transporting large bales which otherwise exceed the lift capacity of the three point hitch system of the tractor. In the alternative the pivoting platform may be carried on a separate wheeled trailer for support, the trailer being pulled by a tractor or other tow vehicle. With this equipment, the utilization of large rectangular bales in small farm operations, such as horse farms and the like, becomes practical. In addition to the cross conveyor on the platform deck, cut-off devices for insuring the break up of the bale as it is dispensed may be mounted as part of the pivoting platform. Such cut-off devices may comprise small sickle bars, rotating arm structures or even ram shears such as illustrated in my co-pending application Ser. No. 09/370,359. Although the cut bale will normally break in natural “flakes” as the bale is advanced over the side of the conveyor, such conditions as freezing weather may require the use of a cut-off device to aid in breaking the bale apart.
Horizontal support structures 8 are rigidly connected at their inner ends to the mast structure 2 and extend outwardly therefrom at right angles. The structures 8 may be braced for vertical support by the braces 9 so as to form a rigid shelf or base support frame for supporting the pivoted pick-up and support platform. It will be understood that the members 8 and 9 may be connected by any suitable bracing structures in order to provide the support shelf. The L-shaped platform is schematically illustrated and indicated generally at 11 in

While the preferred embodiments of the invention have been described herein it is to be understood that the foregoing description and accompanying drawings have been given by way of illustration and example. Variations in design and arrangement of parts may be made without departure from the scope and spirit of the present invention. For example, electrical, hydraulic or pneumatic motor means or manual operated means may be substituted for the various motors described or a combination of electrical, pneumatic, hydraulic motor means and manual operation may be utilized to perform the various operations described. The present invention is not intended to be limited to any particular type of motor vehicle, trailer or the conveyance. Changes in form of the several parts, substitution of equivalent elements and arrangement of parts which will readily be apparent to one skilled in the art, are also contemplated as within the scope of the present invention.
The present application is a continuation of my prior pending patent application Ser. No. 10/508,382, filed Sep. 20, 2004 as a National Stage Entry of my PCT Application No. PCT/US03/08870, filed Mar. 21, 2003, claiming priority from my U.S. Provisional application Ser. No. 60/367,538, filed Mar. 22, 2002.
