2 Claims.
This invention relates to a trash roll construction for a corn picker.
It is known to use trash rolls on a corn picker for removing corn ears from stalks which have broken from the ground. It is desirable to make the spacing between the trash rolls adjustable for varying conditions and, if one trash rollis driven by the other by means of meshing gears fixed to the rolls, the spacing between the rolls may become so great that the one gear does not mesh with the other sufficiently for driving. The present invention has to do with an overcoming of this drawback.
An object of the present invention is to provide an improved trash roll construction for a corn .picker.
A further object is the provision of a novel driving means for trash rolls of a corn picker.
A further object. is to provide a new and improved mounting for trash rolls of a corn picker.
Other objects will appear from the disclosure.
According to the present invention, one trash roll of a pair of rolls, which is movable with respect to the other of the pair of rolls, is mounted so as to swing about a pivot and is driven by means which includes a member mounted upon the pivot. With this arrangement the movable trash roll is always driven whatever its position with respect to the other trash roll.
In the drawing:
Figure l is a side view of a tractor-mounted corn picker employing the novel trash roll con: struction of the present invention;
Figure 2 is a side view showing only a portion of what is shown in Figure 1; and
Figures 3 and 4 are detail views showing a trash roll construction.
of the corn picker. Secured to the shaft 23 outside the side sheet 2| is a sprocket 23. The movable trash'roll I9 is mounted upon a shaft 2| joumaled in arms 25 and 23 mounted upon a shaft 21 joumaled in the side sheets 2| and 22. A gear 28 is secured to the shaft 24 and meshes with a gear 29 mounted upon the shaft 21. A sprocket 30 is mounted upon the shaft 21 so as to be fixed to the gear 23. A sprocket chain 3| drives the sprockets 23 and 30 and is itself driven by a gear 32 mounted upon a shaft 33 carrying a sprocket 34 in mesh with a chain 35. The sprocket 34 and chain 35 may form a part of the drive for the elevator previously referred to by which corn ears are conveyed from the snapping rolls!!! to the husking rolls l5. Secured to the side sheets 2| and 22, as by soldering or welding, are elements 36 and 31 projecting beyond the rear edges of the sheets. Bolts 33 project through the elements 38 and 31, respectively, and have bent end portions 39 which project through openings in the arms 25 and 26. Nuts 40, threaded to the other end of the bolts 38, retain spiral springs 4! between them and the elements 38 and 31. By the arrangement just described the arms 25 and 26 are resiliently urged downwardly so as to urge the upper movable trash roll toward the lower stationary trash roll.
In operation, corn stalks broken from the ground are stripped of the ear attached thereto by the trash rolls I8 and 19 between which they pass. When larger stalks pass between the trash rolls, the upper roll l9 may moveupwardly against the action of the springs 4|. As previously stated the sprockets 23 and 30 are driven by the sprocket chain 3|. The sprocket 23, of course, drives the stationary trash roll it, and the sprocket 30 drives the gear 23, which, in turn, drives the gear 28, which drives the movable trash roll it. Any movement of the upper trash roll it toward or away from the stationary trash roll 18, due to variation in size of trash 5 and stalks passed between the rolls, does not tion that a new and novel trash roll construction has been provided and that this construction includes means by which the rolls are constantly driven, regardless oi the spacing between them.
The intention is to limit the invention only within the scope of the appended claims.
What is claimed is:
1. In a corn picker, a pair of spaced side sheets, a pair of trash rolls for removing corn ears i'rom stalks broken tromthe ground, means rotatably mounting one trash roll in the side sheets, a shaft rotatably mounted in the side sheets, a pair of arms pivoted on the shaft outside the side sheets for pivoting with respect to the side sheets, means rotatabiy mounting the other trash roll on the arms, whereby the said other trash roll is movable toward and away from the said one trash roll by virtue of pivoting of the arms on the side sheets, means driving the said one trash roll, a first sprocket secured to the said one trash roll, a second sprocket mounted on the shaft, a chain driving both sprockets, a first gear secured to the second sprocket, and a second gear meshing with the first gear and secured to the said other trash roll.
2. In a corn picker specified in claim 1, there being resilient means acting between one arm and a side sheet to urge the said other trash roll
