Abstract:
An axial crop processing unit for an axially arranged rotary agricultural combine, comprising:a rotor, having an infeed section for receiving harvested crop material, a threshing section for threshing the harvested crop material from the infeed section, and a separating section for separating grain from the threshed crop material received from the threshing section, the separating section having crop engaging elements, a discharge section merging with the separating section for discharging crop material other than grain from the axial crop processing unit, the discharge section having crop engaging elements that are the same as those used in the separating section, the rotor having a direction of rotation; the direction of rotation of the rotor defining a downward swept side, and upward swept side and a bottom dead center located between the upward swept side and the downward swept side in the discharge section, the discharge section being provided with a metering edge for metering the flow of crop material from the rotor, the metering edge having a downward swept edge corresponding to the downward swept side of the discharge section and an upward swept edge corresponding to the upward swept side of the discharge section and a bottom dead center that corresponds to the bottom dead center of the discharge section, the metering edge being asymmetrical with the downward swept metering edge being more open that the upward swept metering edge.
