Abstract

Abstract A stack processor and method of using the same in which a stack is moved onto a transporting bed through chain flights and advanced thereon during the processing operation by energization and operation of the chain flights to move the stack relative to a pivoted shredding head, the head having a pair of oppositely pitched augers mounted on a shaft with shredding knives positioned on the flights of the augers to loosen and shred compacted material in the stack and advance the same toward a discharge opening in the head wherein it is deposited by gravity onto a conveyor positioned transverse to the extent of the bed for discharge of the shredded crop material therefrom.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 168 words
A stack processor for shredding a stack of harvested crop and conveying the shredded material away from the stack comprising, a wheeled support having a stack supporting bed on the same, an upright support positioned on said bed of said wheeled support and spaced therefrom, means positioned on said bed for advancing the stack in the direction of the upright support, a shredding frame pivotally mounted on the upper end of the upright support and mounting a shaft having a pair of oppositely pitched augers spaced apart thereon and extending across the width of the bed, said augers having shredding knives mounted on the flights thereon in circumferentially and longitudinally spaced positions, a lateral conveyor mounted on the wheel support between the bed and the upright support to receive shredded material from the stack and convey it away from the stack in a direction transversed to the direction of movement of the stack, and means on the wheeled support for rotating the augers and pivoting the shredding frame.
Claim 2
Dependent Claim 168 words
A stack processor for shredding a stack of harvested crop and conveying the shredded material away from the stack comprising, a wheeled support having a stack supporting bed on the same, an upright support positioned on said bed of said wheeled support and spaced therefrom, means positioned on said bed for advancing the stack in the direction of the upright support, a shredding frame pivotally mounted on the upper end of the upright support and mounting a shaft having a pair of oppositely pitched augers spaced apart thereon and extending across the width of the bed, said augers having shredding knives mounted on the flights thereon in circumferentially and longitudinally spaced positions, a lateral conveyor mounted on the wheel support between the bed and the upright support to receive shredded material from the stack and convey it away from the stack in a direction transversed to the direction of movement of the stack, and means on the wheeled support for rotating the augers and pivoting the shredding frame.
Claim 3
Dependent Claim 47 words
The stack processor of claim 1 and including a linear actuator pivotally connected between the upright support and the shredding frame for pivoting the shredding frame with the shaft and augers at the extremity of the same through an arc relative to a stack on the bed.
Claim 4
Dependent Claim 42 words
The stack feeder of claim 2 and including mechanical drive means positioned on the upright support and coupled through a mechanical drive means along the extent of the upright support and the shredding frame to rotate the shaft with pitched augers thereon.
Claim 5
Dependent Claim 25 words
The stack feeder of claim 3 in which the mechanical drive means on the upright support and shredding frame is a chain and gear drive.
Claim 6
Dependent Claim 30 words
The stack feeder of claim 3 and including an additional drive means coupled to the mechanical drive on the wheeled support and coupled to the conveyor for driving the same.
Claim 7
Dependent Claim 55 words
The stack feeder of Claim 5 in which the wheeled support has a hitch at the extremity of the same adjacent the upright support adapted to be connected to a towing vehicle and in which the mechanical drive has a shaft extending therefrom adapted to be connected to a power take-off of the towing vehicle.
Claim 8
Dependent Claim 56 words
The stack feeder of claim 1 and including hydraulic actuator means pivotally connected between the shredding frame and the upright support for pivoting the shredding frame through an arc relative to a stack on the bed and an hydraulic drive means coupled to the mEans on the bed for advancing the stack to drive the same.
Claim 9
Dependent Claim 37 words
The stack feeder of claim 1 in which the oppositely pitched augers have an open center spacing therebetween with paddles having teeth thereon and in which the augers overly the edge of the bed adjacent the conveyor.
Claim 10
Independent Claim 135 words
THE METHOD OF FEEDING A STACK OF HARVESTED CROP WHICH INCLUDES THE STEPS OF LOADING A STACK ON TO A SUPPORT; ADVANCING THE STACK ON THE BED SUPPORT IN A STEP-BY-STEP MOTION UNTIL THE EDGE OF THE STACK IS ADJACENT ONE END OF THE BED SUPPORT PIVOTING A SHREDDER THROUGH THE STACK FROM THE TOP THEREOF AND THROUGH AN ARC TOWARD THE BOTTOM EDGE OF THE STACK AND ADJACENT THE BED; CAUSING THE MATERIAL IN THE STACK TO FALL BEYOND THE EDGE OF THE STACK AND THE BED SUPPORT; COLLECTING THE SHREDDED MATERIAL AND CONVEYING THE SAME WAY FROM THE STACK IN A DIRECTION TRANSVERSED TO THE DIRECTION OF ADVANCEMENT OF THE STACK; AND REPEATING THE STACK ADVANCING, SHREDDINING AND MATERIAL COLLECTING AND REMOVING STEPS SUCCESSIVELY UNTIL THE STACK IS TOTALLY UNLOADED FROM THE SUPPORT.
Claim 11
Independent Claim 135 words
THE METHOD OF FEEDING A STACK OF HARVESTED CROP WHICH INCLUDES THE STEPS OF LOADING A STACK ON TO A SUPPORT; ADVANCING THE STACK ON THE BED SUPPORT IN A STEP-BY-STEP MOTION UNTIL THE EDGE OF THE STACK IS ADJACENT ONE END OF THE BED SUPPORT PIVOTING A SHREDDER THROUGH THE STACK FROM THE TOP THEREOF AND THROUGH AN ARC TOWARD THE BOTTOM EDGE OF THE STACK AND ADJACENT THE BED; CAUSING THE MATERIAL IN THE STACK TO FALL BEYOND THE EDGE OF THE STACK AND THE BED SUPPORT; COLLECTING THE SHREDDED MATERIAL AND CONVEYING THE SAME WAY FROM THE STACK IN A DIRECTION TRANSVERSED TO THE DIRECTION OF ADVANCEMENT OF THE STACK; AND REPEATING THE STACK ADVANCING, SHREDDINING AND MATERIAL COLLECTING AND REMOVING STEPS SUCCESSIVELY UNTIL THE STACK IS TOTALLY UNLOADED FROM THE SUPPORT.
Claim 12
Dependent Claim 37 words
The method of feeding from a stack of claim 9 in which the shredding step moves the material in the stack toward the center of the stack as it falls by gravity to the collecting conveying means.
