Abstract
An axial flow harvesting machine having at least one generally cylindrical rotor rotatably mounted within a casing and operable, in conjunction with the casing, to thresh and separate grain from straw material, and a plurality of threshing elements provided around the periphery of the rotor is disclosed wherein the threshing elements are staggered along the axis of the rotor and configured for optimum crop flow along the rotor. The threshing elements are also arranged to overlap axially, and preferably also circumferentially, with respect to the associated rotor.
Claims8
In an axial flow harvesting machine having at least one generally cylindrical rotor defining a generally longitudinally extending axis and being rotatably mounted within a casing and operable, in conjunction with the casing, to thresh and separate grain from straw material, and a plurality of threshing means provided around the periphery of said at least one rotor and being staggered axially thereof, the improvement comprising:
- said adjacent threshing means overlapping with respect to the axis of said at least one rotor.
