Abstract: PURPOSE: To evenly bring unhulled rice into collision against the entire periphered of a rubber body of an impact section of an impact body and to prevent the local wear of this rubber body by providing the impact section with the rubber body freely turnably along a spherical surface. CONSTITUTION: The unhulled rice flowing in from a supply port 5 is shaken out by a shaking-out port 12 at the front end of a shaking-out body 10 and collides against the top of the rubber body 29 on the inside surface disposed in the impact section 15 of the impact body 13 and its chaff is peeled off and guided downward, At this time, an arm rod 243 projecting from a horizontal turning ring 14 of the impact body 13 moved integrally with this turning ring 14 and the roll at the front end of the arm rod 23 moves horizontal. The horizontal annular 25 part of the impact section 15 moves successively upward and the part on the opposite side thereof descends around the shaft and shaft rod 28.  The rubber body 29 turns along the spherical surface in such a manner and the surfaces of the shaking-out port 12 and the rubber body 29 of the impact section 15 eventually change by maintaining always in the same state. Consequently, the rice collides uniformly against the entire peripheral of the rubber body 29 and the local wear of the rubber body 29 does not occur. The unhulled rice blown out of the shaking-out port 12 is thus smoothly guided downward.
