An axial flow combine having a crop harvesting header including a feeder for cutting a crop and feeding it rearwardly into a threshing and separating mechanism. The mechanism includes a casing for receiving the crop material and a rotor within the casing for threshing and separating grain from the crop material. The rotor has a central drive shaft driven through a gear case behind the rotor. The gear case is partially enclosed within a cover having a smooth exterior surface. The end of the rotor is configured in a smooth exterior surface which is complementary to the surface of the cover to inhibit collection of chaff about the drive shaft. Impeller blades are secured on the rotor for creating an air flow directing crop material away from the drive shaft to prevent crop material wrapping about the shaft or accumulating in the drive system.

Combine rotor drive anti-trash system

An axial flow combine having a crop harvesting header including a feeder for cutting a crop and feeding it rearwardly into a threshing and separating mechanism. The mechanism includes a casing for receiving the crop material and a rotor within the casing for threshing and separating grain from the crop material. A plurality of crop material directing vanes is disposed within the casing and cooperate with the rotor in directing the material generally helically along the casing. Means are included for selectively and simultaneously adjusting the position of the vanes to change the rate of movement of the crop material through the casing.

Adjustable transport vanes for axial flow combine

A general purpose rasp bar carrying rotor construction for an axial flow-type harvester combine embodying a vaned impeller and a series of bars which cooperate with elements within the surrounding rotor casing for crop threshing and grain separation purposes in a novel and efficient manner. The rotor proper is generally of imperforate tubular cylindrical construction so that the crop material in its entirety is confined to the annulus which exists between the rotor and its casing. The threshing portion of the rotor having both helical and longitudinal extending rasp bars.
