Abstract

Abstract A stacking implement picks the precut crop off the ground, elevates the crop and blows it into a wagon. The crop is periodically compressed in the wagon, a crop-distributing deflector in the wagon is tilted in response to actuation of the compressor, and a stack unloading ramp is also raised and lowered by actuating the compressor.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 288 words
In a farm implement: an open bottom housing having an upright outlet tube extending upwardly therefrom; a rotor mounted in the housing for rotation about a generally horizontal axis traversing the normal path of travel of the implement, said rotor being provided with a plurality of blades each swingable at the inner end thereof about an axis parallel with the axis of rotation of the rotor, each blade being provided with an uninterrupted, elongated, transversely flat, leading surface extending from its axis of swinging movement to its outermost tip end for physically contacting a crop lying on the ground to forcibly transfer the crop from the ground, upwardly into the housing through the open bottom thereof, and thence upwardly into said tube, there being an air scoop on each of said surfaces extending outwardly from said inner end of the blade for acting on the air flowing into the housing with said crop to produce a crop-advancing air blast directed upwardly into said tube as initiated by said impact, said scoop having a concave portion remote from said inner end of the blade, each surface including an elongated, flat impact paddle between said concave portion and said tip end of the blade, each paddle being rectangular and provided with a transverse axis normally radial to said axis of rotation of the rotor; and a container separate from the tube and shiftable relative thereto for receiving the crop from said tube, said container being provided with a deflector for distributing the crop evenly within the container as the crop is fed thereinto, said deflector being shiftably secured to the container therewithin for varying the position of the deflector relative to the flow of the crop issuing from said tube.
Claim 2
Dependent Claim 288 words
In a farm implement: an open bottom housing having an upright outlet tube extending upwardly therefrom; a rotor mounted in the housing for rotation about a generally horizontal axis traversing the normal path of travel of the implement, said rotor being provided with a plurality of blades each swingable at the inner end thereof about an axis parallel with the axis of rotation of the rotor, each blade being provided with an uninterrupted, elongated, transversely flat, leading surface extending from its axis of swinging movement to its outermost tip end for physically contacting a crop lying on the ground to forcibly transfer the crop from the ground, upwardly into the housing through the open bottom thereof, and thence upwardly into said tube, there being an air scoop on each of said surfaces extending outwardly from said inner end of the blade for acting on the air flowing into the housing with said crop to produce a crop-advancing air blast directed upwardly into said tube as initiated by said impact, said scoop having a concave portion remote from said inner end of the blade, each surface including an elongated, flat impact paddle between said concave portion and said tip end of the blade, each paddle being rectangular and provided with a transverse axis normally radial to said axis of rotation of the rotor; and a container separate from the tube and shiftable relative thereto for receiving the crop from said tube, said container being provided with a deflector for distributing the crop evenly within the container as the crop is fed thereinto, said deflector being shiftably secured to the container therewithin for varying the position of the deflector relative to the flow of the crop issuing from said tube.
Claim 3
Dependent Claim 41 words
In a farm implement as claimed in claim 1, wherein said deflector is provided with means for guiding part of the crop toward one side of the container and the remainder of the crop toward the other side of the container.
Claim 4
Dependent Claim 274 words
In a farm implement, a combination crop pickup and conveying unit comprising: an open bottom housing having an upright outlet tube extending upwardly therefrom; a rotor mounted in the housing for rotation about a generally horizontal axis traversing the normal path of travel of the implement, said rotor being provided with a plurality of blades each swingable at the inner end thereof about an axis parallel with the axis of rotation of the rotor, each blade being provided with an elongated impact surface extending from its axis of swinging movement to its outermost tip end for physically contacting a crop lying on the ground to forcibly transfer the crop from the ground, upwardly into the housing through the open bottom thereof, and thence upwardly into said tube, there being an air scoop on each of said surfaces for acting on the air flowing into the housing with said crop to produce a crop-advancing air blast directed upwardly into said tube; a container for receiving the crop from said tube, said container being provided with a deflector for distributing the crop evenly within the container as the crop is fed thereinto, said deflector being shiftable for varying the position of the deflector relative to the flow of the crop issuing from said tube, said container being provided with a movable compressor for periodically compacting the crop within the container to form a stack conforming in shape with the container, said deflector being mounted on the compressor for movement therewith; and structure including an anchor and means interconnecting the anchor and said deflector for shifting the deflector relative to the compressor as the latter is moved.
Claim 5
Dependent Claim 274 words
In a farm implement, a combination crop pickup and conveying unit comprising: an open bottom housing having an upright outlet tube extending upwardly therefrom; a rotor mounted in the housing for rotation about a generally horizontal axis traversing the normal path of travel of the implement, said rotor being provided with a plurality of blades each swingable at the inner end thereof about an axis parallel with the axis of rotation of the rotor, each blade being provided with an elongated impact surface extending from its axis of swinging movement to its outermost tip end for physically contacting a crop lying on the ground to forcibly transfer the crop from the ground, upwardly into the housing through the open bottom thereof, and thence upwardly into said tube, there being an air scoop on each of said surfaces for acting on the air flowing into the housing with said crop to produce a crop-advancing air blast directed upwardly into said tube; a container for receiving the crop from said tube, said container being provided with a deflector for distributing the crop evenly within the container as the crop is fed thereinto, said deflector being shiftable for varying the position of the deflector relative to the flow of the crop issuing from said tube, said container being provided with a movable compressor for periodically compacting the crop within the container to form a stack conforming in shape with the container, said deflector being mounted on the compressor for movement therewith; and structure including an anchor and means interconnecting the anchor and said deflector for shifting the deflector relative to the compressor as the latter is moved.
Claim 6
Dependent Claim 79 words
In a farm implement as claimed in claim 3, wherein said container has an open end and means is provided within the container for moving the stack toward said open end, and wherein is provided a ramp on the container at said open end swingable into and out of closing relationship to said open end, there being means operably coupling the compressor with the ramp for controlling the swinging of the ramp in response to movement of the compressor.
