| 摘要 |
This patent application refers to a rotary threshing and separation unit, comprising a rotor housing (12) 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 (16) arranged in said rotor housing, beater plates fixed on said threshing and separation rotor, and sucking air flow stream generating means (18) sucking an air flow stream from the discharge zone through the rotor housing. To increase the feeding performance of a rotary threshing and separation unit it is suggested that there are guiding elements (20, 21) arranged in the discharge zone, which are projecting over the inner surface of the rotor housing to an extent to which they allow straw and chaff to be sucked out of the rotor housing but retain grain kernels inside, or which are rotatably arranged on the shaft of the sucking blower so that inclined deflection surfaces (40, 41) being part of the guiding elements may kick grain kernels back into the rotor housing.
