Abstract
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 th…
