摘要： In an axial flow combine, an improved inlet transition area for changing the flow of crop materials from a linear ribbon-like flow through the feeder to an arcuate ribbon-like flow about the flighting of the inlet end of the rotor to a helical sleeve flow between the rotor and rotor casing while at the same time injecting crop materials in all portions of the flighting. A sloping ramp extends upwardly and rearwardly from the feeder to an elliptical intersection with the rotor casing. A pair of oppositely disposed sidewalls in generally perpendicular relation to the ramp extend from the feeder and converge about the inlet end of the rotor at an upper portion of the rotor casing. Another wall between the sidewalls, oppositely disposed from the ramp, encloses the inlet transition area. A rotary beater disposed between the sidewalls and in close proximity to the inlet end of the rotor rotates at a higher tangential velocity than the feeder to direct and accelerate the crop materials upwardly and rearwardly along the sloped ramp and the converging sidewalls to entrain the crop materials about all portions of the flighting of the rotor in an arcuate ribbon-like manner. All of the surfaces of the inlet transition area are either planar or cylindrical for ease and economy of manufacture and fabrication. Related methods are disclosed.

摘要： Apparatus for discharging threshed crop materials, in a relatively uniform manner across the body width of the combine, directly from the discharge end of a threshing and separating rotor in an axial flow combine without the need for additional apparatus at the discharge end of the rotor to discharge the threshed materials or to avoid plugging or bunching of crop materials between the rotor and rotor casing. The rotor extends longitudinally through the combine to a discharge area at the discharge end of the rotor. The rotor casing closely surrounds the rotor near the discharge end and guide vanes disposed in the rotor casing cooperate with separating elements circumferentially disposed about the rotor near the discharge end to positively move threshed materials toward the discharge end of the rotor. The casing terminates short of the discharge end of the rotor in progressively increasing angular widths in the direction of the discharge end such that the materials are tangentially discharged from differing circumferential points of the rotor exposed by the casing terminations for a multi-stream discharge. A deflector plate disposed below the exposed portions of the rotor deflects the discharged materials rearwardly for enhanced dispersion and reduces the discharge velocity.

摘要： A low profile axial flow combine with a low center of gravity for improved stability, with reduced overall machine height for ease of shipping and with high capacity grain tank of the saddle type. A threshing and separating rotor, in coaxial relationship to a rotor casing, extends longitudinally and approximately horizontally in the combine to the discharge end for low rotor discharge of the threshed materials. Cleaning apparatus including the grain pan, the separator pan, the chaffer, the sieve screen and the blower are compactly nested beneath the rotor casing. A high capacity saddle grain tank extends over and down opposite sides of the rotor casing. A discharge auger extends transversely through the boots of the grain tank and through an auger housing interconnecting the boots. The upper end of the grain pan extends over the auger housing interconnecting the grain tank boots. The lower end of the grain pan is stepped.
