The feed hopper is set with a limiting component. Through the operation of the limiting component, the rice enters the box body in batches, which helps to avoid the phenomenon of clogging caused by too much rice falling at one time, which is conducive to maintaining the filtering effect of the equipment. The rice falls into the screening bucket through the feed hopper, and then The sieve bucket is struck by the striking assembly to generate vibration, thereby improving the screening efficiency of the sieve bucket, avoiding blockage of the sieve bucket, and maintaining the screening effect of the sieve bucket. A telescopic assembly is provided between the sieve bucket and the carrying plate. When the striking assembly is in operation, the sieve bucket slides up and down. The telescopic assembly can act as a buffer and facilitate the stable up and down sliding of the sieve bucket.

When the rubber hammer is separated from the screen bucket, the support rod moves downward under the traction of the second spring of the same group, and then the above operation is repeated, so that the screen bucket continuously slides up and down, which is beneficial to improve the screening efficiency of the screen bucket.

[0017] Furthermore, the air blowing assembly includes a U-shaped tube fixedly mounted on the top of the supporting plate, a plurality of air outlet holes distributed in a curved array are provided on the surface of the U-shaped tube, a support plate is fixedly mounted on the side of the box away from the door panel, a blower is fixedly mounted on the top of the support plate, a duct is provided on one side of the blower, and the end of the duct away from the blower passes through the box and is connected to the side opposite to the U-shaped tube, an exhaust pipe is fixedly mounted on the top of the box, one end of the exhaust pipe is connected to a dust filter bag, and an anti-backflow bag is provided in the dust filter bag.

A telescopic assembly is provided between the sieve bucket 7 and the carrying plate 2. When the striking assembly is running, the sieve bucket 7 slides up and down. The telescopic assembly can play a buffering role and facilitates the stable sliding of the sieve bucket 7 up and down.
