Abstract
A rotary threshing and separation unit, comprising a rotor housing with a feeding zone, a separation zone and a discharge zone, parts of the circumferential housing being closed and other parts having openings, a rotary driven threshing and separation rotor arranged in the rotor housing, beater plates fixed on the threshing and separation rotor, and sucking air flow stream generating device sucking an air flow stream from the discharge zone through the rotor housing. Guiding elements arranged in the discharge zone, which are projecting over the inner surface of the rotor housing to an extent to which they allow chaff to be sucked out of the rotor housing but retain grain kernels inside. Helical vanes in at least the first half of the length of the rotor housing are projecting over the inner surface of the rotor housing and are at an angle or inclined towards the feeding direction of the harvested crop to support the feeding action. The incline angle of the helical vanes is adjustable which will regulate the feeding action inside of the rotor housing.
