Wind force material lifting corn thresher

The utility model relates to a wind force material lifting corn thresher which comprises a machine frame (1), a threshing bin (2), a threshing roller (3), a vibrating screen (4) and an impurity discharging fan (5). The rear potion of a material outlet of the vibrating screen (4) on the machine frame (1) is provided with a material lifting centrifugal fan (6), and an axial air inlet of the material lifting centrifugal fan (6) is provided with a material inlet chute (61) formed below the rear portion of a material outlet chute (41) of the vibrating screen (4). A material outlet in the tangential direction of the material lifting centrifugal fan (6) inclines upwards and is connected with a winnowing cylinder (62) with the other end inclining upwards. The wind force material lifting corn thresher is high in working efficiency and capable of reducing labor capacity and better saving labor and physical strength. Disengaged corn kernels can be lifted and fall from a high position under wind force and can be directly
