After the rice is output from the belt elevator 1, it enters the feeding hopper 23, and finally enters the inside of the cover 21, and different sizes of rice are discharged from different discharge ports 24 through the screening subassembly 22.
[0039] It should be noted that the belt elevator 1 is a conventional device purchased in the market, and its specific structure and working principle are prior art disclosed, and the drawing only shows the transmission belt part of the belt elevator 1, which is used to show the cooperation relationship between the belt elevator 1 and the agitating mechanism 3, and the other parts of the belt elevator 1 are not shown.

[0051] The components not described in detail herein are prior art.
[0052] The working principle and use process of the utility model are as follows: when the utility model is used, the large rice to be screened is conveyed by the belt elevator 1, and is lifted to the inlet hopper 23, during which the third driving motor 34 is started to drive the hole mounting lug 31 to rotate, and the knocking rod 32 is driven to do circular motion and knock the belt of the belt elevator 1, so that the belt is vibrated, thereby making the large rice on the transmission belt have a certain displacement, and making the large rice more evenly distributed on the transmission belt, avoiding the problem of blockage or overflow caused by too much large rice, and improving the safety of work.
