Abstract: There are provided a first belt-clutch mechanism switching power transmission to a first large-diameter pulley, and, at the same time, a second belt clutch mechanism switching power transmission to a second large-diameter pulley, and a first and a second belt clutch mechanism are provided with a first and a second arm members, tension clutch pulleys installed at point portions of these arm members, and actuators which rotate a first and a second arm members in such a way that a position at which a first no-end belt is wound on the first large-diameter pulley is switched to a position at which winding is avoided, and, at the same time, a position at which a second no-end belt is wound on a second large-diameter pulley is switched to a position at which winding is avoided.

Abstract: A rotatively oscillating separator comprising separating vessels 4 each having cone-shaped separating plate 5 disposed in the vessel, and drive means 6 for rotatively oscillating said separating vessels 4, mixed rice consisting of unhulled rice and unpolished rice being fed onto the separating plates in the separating vessels at a given location to separate the unhulled rice and the unpolished rice from each other, the unpolished rice being discharged through raised peripheral portions of the vessels, and the unhulled rice being discharged through the central bottoms of the separating vessels.

Abstract: A rotary shaking separator for separating unhulled rice and unpolished rice from each other includes at least one separating vessel and a plurality of drives located at even intervals on the peripheral edge of the separating vessel, the plurality of drives being actuated to bring the whole of the separating vessel into a rotationally shaking motion.

Abstract: A rotationally oscillating separator for separating mixed rice into unhulled rice and unpolished rice after the rice have passed through a rice huller to remove the hulls from rice.

Abstract: An object of the present invention is to provide a rotary shaking separator, which can maintain a constant separating accuracy without any failure in separation which might possibly occur in the same separating vessel, and which is not required to have a rotary shaft inserted though a central portion of the separating vessel.
