Abstract: A shroud for the infeed section impeller in a rotary combine. The shroud includes a rear converging wall cone and a front diverging wall cone. A feed plate extends transversely across the front of the shroud and a sump is formed in the shroud behind the feed plate. The front diverging wall cone comprises top and bottom, rearwardly diverging walls. Transitions castings separate the top and bottom walls on left and right sides and have rearwardly converging front faces.

Abstract: A threshing rotor and front bearing housing shroud assembly for an agricultural combine having improved anti-wind characteristics, particularly with regard to long, wet straw. The invention resides in a front rotor inlet or infeed section having at least one radially outwardly extending impeller or auger flight having a front leading edge extending radially outwardly from a front center portion so as to be swept back relative to the rotational direction of the auger and so as to radiate from inwardly of, and form at least a 90 degree included angle in relation to, a wiping surface and anti-wind wiper of the shroud. A generally annular space exists between the shroud and a front bearing housing substantially surrounded thereby, and at least one radially outwardly raked anti-wind lug on the front center portion of the inlet section rotates through the space to agitate and clear plant material therefrom through pathways provided through the shroud for the flow of the plant material from the space.

Abstract: A rotor assembly for an agricultural combine includes a rotor, a plurality of short thresher elements and a plurality of elongated thresher elements. The short thresher elements and a plurality of elongated thresher elements are arranged on the rotor so that the crop material contacts at least two short thresher elements before contacting an elongated element, thereby breaking up clumps of crop material before the clumps contact an elongated element. The agricultural combine has a rotor having a front portion, a rear portion a plurality of elongated thresher elements. Each elongated thresher element is aligned along a separate longitudinal line which extends from the front portion to the rear portion, to prevent a roll of material from building across multiple elongated thresher elements.

Abstract: An infeed assembly for a rotary combine has an impeller for directing crop materials outwardly and rearwardly. The impeller is arranged on the infeed section of the rotor and includes impeller blades that redirect the incoming mat-like crop materials into a whirling, circulatory motion and also translates the crop materials rearward towards the rotor's threshing section. Each blade has a leading edge that is swept back in two dimensions. Each leading edge is simultaneously swept back circumferentially away from the direction of impeller rotation and axially towards the rotor's threshing section. The pitch of each blade increases for a predetermined distance rearwardly.

The threshing rotor comprises an elongated drum having a generally cylindrical outer wall defining a smooth outer surface or skin extending along the length of the drum and having a plurality of straps or bands circumferentially arranged about and disposed along the outer wall of the rotor. Each band or strap has at least one threshing element connected thereto. A clamp mechanism releasably secures each strap against the outer wall of the drum and permits the strap and the threshing element connected thereto to be quickly replaced and/or shifted relative to adjacent threshing elements carried by adjacent straps. The threshing rotor further includes stops provided on opposite sides of each strap to inhibit longitudinal shifting of the strap along the outer wall of the rotor during a threshing operation.
