Description

Technical field: [0001] The invention relates to a screening unit in a device for removing rice grains. Background technique: [0002] The removal of rice grains is achieved by using the weight difference between empty grains and broken straws. During the falling process of rice, since the weight of empty grains and broken straws is less than the weight of rice, under the action of wind, the empty grains and broken straws can be removed. Shredded straw purposes. But this kind of method can not remove the pebbles in the rice. Invention content: [0003] The present invention provides a screening unit in a rice chaff removal device in order to solve the problems in the above-mentioned prior art. [0004] The technical scheme adopted in the present invention includes: a screening unit in a rice chaff removal device, including a base, a screen frame, a screen, a first guide rod, a first spring, a second guide rod, a second spring, a support frame, cam, arc block and drive m...
