Abstract
Abstract A tow-type haystack forming vehicle includes a vehicle body having ground-engaging wheels and adapted to receive a chopped forage crop such as hay from a crop harvesting device or a crop pickup device. A compaction roller and guide structure are positioned within the vehicle body and the roller is continuously moved in a front and rear direction along the surface of the forage crop to compact the crop during the stack forming operation. A telescopic tubular distributor mechanism is connected to the discharge spout of the forage harvester or crop pickup device and is operable to evenly distribute the crop in the vehicle body. The bottom wall of the vehicle body is shiftable from a forward position to a rearward position rearwardly of the vehicle body whereby the formed stack supported on the bottom wall will be discharged upon the ground when the rear doors for the vehicle body are closed and the bottom wall is then shifted to the forward position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
275 words
A stack forming vehicle adapted to be towed by a prime mover and adapted to receive a chopped forage crop from a crop harvesting or crop pickup device of the type having a discharge spout through which the chopped forage crop is discharged, comprising: a generally rectangular shaped vehicle body including a bottom wall, a front wall, upstanding substantially opposed vertical side walls, a closure structure shiftably mounted on said vehicle body adjacent the rear end thereof and being swingable between a closed position for closing the rear end of the vehicle body, and an open position to permit a formed stack to be removed rearwardly from the vehicle body, ground engaging wheels, means connecting the ground engaging wheels with said vehicle body to permit travel thereof over the surface of the ground, an elongate revolvable compacting roller extending transversely of said vehicle body and having a length dimension slightly less than the interior width dimension of the vehicle body, said compacting roller being reciprocable in a front and rear direction in the vehicle body along the surface of the forage crop during loading of the vehicle body to continuously compact the forage crop therein, an elongate guide structure engaged by said compacting roller and guiding the latter during its reciprocating movement, drive means operatively connected with said compacting roller and being operable for reciprocating the latter, a shiftable distributor mechanism in the vehicle body and adapted to be connected to the discharge spout of the crop harvesting device and being shiftable in a front and rear direction, said distributor being operable when shifted to evenly distribute the chopped forage crop into the vehicle body.
Claim 2
Dependent Claim
275 words
A stack forming vehicle adapted to be towed by a prime mover and adapted to receive a chopped forage crop from a crop harvesting or crop pickup device of the type having a discharge spout through which the chopped forage crop is discharged, comprising: a generally rectangular shaped vehicle body including a bottom wall, a front wall, upstanding substantially opposed vertical side walls, a closure structure shiftably mounted on said vehicle body adjacent the rear end thereof and being swingable between a closed position for closing the rear end of the vehicle body, and an open position to permit a formed stack to be removed rearwardly from the vehicle body, ground engaging wheels, means connecting the ground engaging wheels with said vehicle body to permit travel thereof over the surface of the ground, an elongate revolvable compacting roller extending transversely of said vehicle body and having a length dimension slightly less than the interior width dimension of the vehicle body, said compacting roller being reciprocable in a front and rear direction in the vehicle body along the surface of the forage crop during loading of the vehicle body to continuously compact the forage crop therein, an elongate guide structure engaged by said compacting roller and guiding the latter during its reciprocating movement, drive means operatively connected with said compacting roller and being operable for reciprocating the latter, a shiftable distributor mechanism in the vehicle body and adapted to be connected to the discharge spout of the crop harvesting device and being shiftable in a front and rear direction, said distributor being operable when shifted to evenly distribute the chopped forage crop into the vehicle body.
Claim 3
Dependent Claim
74 words
The stack forming vehicle as defined in claim 1 wherein said guide structure comprises a pair of elongate laterally spaced apart substantially parallel guide tracks, means rigidly interconnecting said tracks, said compacting roller and guide structure being elevated by the crop as the crop fills the vehicle body, means connected with said guide structure for retaining the guide structure and roller in an elevated position as the crop is discharged from the vehicle body.
Claim 4
Dependent Claim
64 words
The stack forming vehicle as defined in claim 1 wherein said distributor mechanism is of tubular construction and is extensible and retractable in a front and rear direction, said tubular distributor mechanism having an outlet adjacent its rear end into which the chopped forage crop is discharged during extension and retraction of the distributor mechanism, and means for extending and retracting said distributor mechanism.
Claim 5
Dependent Claim
73 words
The stack forming vehicle as defined in claim 2 wherein said distributor mechanism is comprised of a plurality of interconnected telescoping tubular sections, and said means for extending and retracting said distributor mechanism is operatively connected with said sections to extend said sections, longitudinally of the vehicle body, whereby said outlet is continuously moved in a front and rear direction between the rear end of said vehicle body and the front end thereof.
Claim 6
Dependent Claim
67 words
The stack forming vehicle as defined in claim 3 and a deflector mounted on said distributor mechanism adjacent the rear end thereof, said deflector presenting a concave deflector surface for deflecting the chopped forage crop discharged from the tubular distributor mechanism downwardly, and means on said concave deflector surface defining distributor veins for evenly distributing the crop in a transverse direction with respect to the vehicle body.
Claim 7
Dependent Claim
98 words
The stack forming vehicle as defined in claim 1 wherein said bottom wall is shiftable between forward and rearward positions, said bottom wall when in the forward position defining the floor of the vehicle body for supporting the chopped crop thereon, and when in the rearward position being disposed rearwardly of the vehicle body, whereby when said closure structure is closed when the bottom is in the rearward position and the bottom wall is them shifted forwardly, the crop stack will be positioned upon the ground, and means for shifting the bottom wall in forward and rearward directions.
Claim 8
Dependent Claim
43 words
The stack forming vehicle as defined in claim 2 and means operatively connected with said guide structure for maintaining the guide structure in a substantially level condition as the guide structure and compacting roller are elevated by the crop during the stack-forming operation.
