摘要:
A rotary crop-processing unit for an agricultural combine in which the rotor is mounted in a rotor housing with the rotor axis diverging from the housing axis in the crop flow direction through the crop-processing unit. The diverging rotor and housing axes enable the gap between the rotor and the top of the housing to increase in the crop flow direction without producing abrupt changes in the housing shape.
