PROBLEM TO BE SOLVED: To improve screening efficiency of a thresher by scattering a treating object on a shaking shelf at a front side of a cross flow fan. SOLUTION: A clamping conveyor (18) composed of a clamping rod (16) and a feed chain (17) is placed along outer right side of the inlet (19) of a threshing chamber (15). A blowing winnower (20), a clean grain transfer screw (21) and a tailing transfer screw (22) are arranged under the shaking-off shelf (3) in the order from the upstream side of screening direction; the cross flow fan (5) is rotatably supported sideways above the rear end of the shaking-off shelf (3), and a dust suction port (6) of the cross flow fan (5) is directed downward and a dust exhaustion port (33) is directed toward outside of the thresher. A threshing cylinder (10) provided with threshing teeth (40) is placed above the shaking-off shelf (3) and left-side of the thresher (1), and the treating object is scattered on the shaking-off shelf (3) at the front side of the cross flow fan (5) by the rotation of the threshing cylinder (10).
