摘要： A kit and method of abrading grain provides multiple components to improve the threshing operation within an agricultural combine. The kit includes a unique concave design, open valley rasp bars, and restrictor plates. The method of abrading grain allows threshing operations for large grains such as corn and, also, for small grains such as soybeans. For example, the kit can be used to facilitate construction of a harvesting system that comprises: a drum of a rotary combine; a straight bar concave in a first position, wherein the straight bar concave utilizing intersecting bars, wherein at least some of said intersecting bars including a sharp leading edge, wherein the sharp leading edge abrades harvested materials and separate grain therefrom when the rotary drum rotates; and a plurality of round bar concaves in at least a second and a third position.

摘要： The disclosure pertains to separably driven rotor portions for a combine harvester and a method for threshing grain using separably-driven rotor portions. The combine harvester is moved through harvest material comprising grain material and material-other-than-grain (“MOG”). The grain material is separated from the MOG using multiple processing areas. The auger portion may be stopped or rotated at a slower speed with respect to rotation of the threshing portion to simulate the gathering of a large amount of crop material even when small plots are involved, thereby providing the benefits of large-plot harvesting to small-plot applications.

摘要： A combine harvester threshing drum threshing bar includes a rigid, integral, unitary threshing fixture having a leading edge and an opposed trailing end, an upstream face and an opposed downstream face formed with an oblique crop deflecting surface, a threshing side and an opposed threshing drum emplacement side. The threshing side includes a trailing threshing face formed toward the trailing end of the threshing fixture, and an inclined leading threshing face extending from the trailing threshing face to the leading edge, and which cooperates with the threshing drum emplacement side and the upstream and downstream faces of the threshing fixture at the leading edge to form a wedge in the threshing fixture. Crop threshing grooves are formed in the trailing threshing face of the top threshing side of the threshing fixture, which extend from the trailing end to the leading threshing face of the threshing fixture.

摘要： A rotating cylinder is used with a complementary fixed concave in a combine to separate grain from the leafy portion of the plant. The elongated cylinder is comprised of a plurality of aligned star-shaped hubs disposed in a spaced manner along its length. An elongated, linear raspbar is attached to each "point" of the aligned star-shaped hubs and extends the length of the cylinder for engaging and urging the plant against the concave and separating the grain from the plant's leafy portion. A flat elongated filler plate is disposed between each pair of adjacent raspbars for preventing the grain and crop residue from entering the hollow cylinder and for displacing the grain and crop residue rearwardly along the concave where it is discharged onto another combine grain processing and separation stage. The flat profile of the filler's plate prevents the grain and crop residue from remaining on the surface of the rotating cylinder for improved grain threshing. The fixed concave includes a plurality of spaced cross bars extending the length thereof and has a tapered profile in proceeding from front to rear. In addition, the spacing between adjacent cross bars of the concave decreases in proceeding from the front, or intake, end of the concave towards its rear, or discharge, end. The increased thickness of and greater separation between adjacent cross bars at the concave's intake end provide improved grain/crop residue separation, while the reduced concave thickness and reduced cross bar separation at its discharge end facilitates crop residue discharge.

摘要： A combination of cylinder bars used with a backing plate for mounting on different lengths of threshing cylinders. The cylinders used with different models of combines for the threshing of grain, chaff and straw. The combination of cylinder bars includes a forward cylinder bar, a reverse cylinder bar and a center cylinder bar. The center cylinder bar is characterized by having both a forward and a reverse tooth configuration. Also, the center cylinder bar may be of various lengths depending on the length of the cylinder. Opposite side portions of the backing plate are bent to match the threshing cylinder radius. The backing plate includes bolt holes to match bolt holes on cylinder flanges on the threshing cylinder. Bolts are used to secure the backing plate to the cylinder. The three cylinder bars are mounted on a top portion of the backing plate. The top portion of the backing plate includes bolt holes to match the configuration of the bolt holes in the forward, reverse and center cylinder bar. Bolts are used for securing the cylinder bars to the backing plate. The combination of using one length of the forward cylinder bar, one length of the reverse cylinder bar and a center cylinder bar of different lengths eliminates the need of having a large inventory of various lengths of one piece.

摘要： A spring-mounted rasp bar sheller for corn is described herein. The sheller comprises a plurality of spaced apart rasp bars mounted on a combine or sheller cylinder. Each of the rasp bars has studs secured thereto which extend therefrom through the cylinder backing plates. Springs are mounted on the studs behind the backing plates for yieldably urging the rasp bar inwardly towards the backing plate. Centrifugal force causes the rasp bar to move out radially towards the concave as the cylinder is rotated. During shelling, impact forces on the rasp bars deflect them radially inwardly. Filler plates are also disclosed for preventing the corn from becoming lodged between the backing plate and the rasp bars.
