[0028] Specifically, impurities pass through the filter screen 16 and fall into the interior of the first collection box 22 along the first feed bin 21, while rice falls into the interior of the second collection box 24 along the second feed bin 23.
[0029] In this embodiment, the cover 3 is threadedly installed on the top of the box 14 by the second bolt, and the top of the feed hopper 4 is fitted with a hopper door.
[0030] Specifically, open the compartment door to facilitate pouring in rice, and unscrew the second bolt from the inside of the cover 3 to facilitate removing the cover 3.
[0031] In this embodiment, the leveling mechanism 5 includes a housing 51. A motor 52 is fixedly installed on the outer wall of the housing 51. The output end of the motor 52 passes through the housing 51 and is fixedly installed with a threaded rod 53. The side of the threaded rod 53 away from the output end of the motor 52 is rotatably connected to the inner wall of the housing 51 through a bearing. A threaded sleeve 54 is installed on the external thread of the threaded rod 53. A movable rod 55 extending into the screening mechanism 1 is fixedly installed on the outside of the threaded sleeve 54. A movable hole is opened inside the housing 14, which matches the movable rod 55. A leveling plate 56 is fixedly installed on the outside of the movable rod 55. A slider extending into the housing 14 is fixedly installed on the outside of the leveling plate 56. A sliding groove is opened inside the housing 14, which matches the slider.
[0032] Specifically, by turning on the motor 52, the motor 52 drives the threaded rod 53 to rotate, and the threaded sleeve 54 drives the moving rod 55 and the spreading plate 56 to move, and the spreading plate 56 spreads the rice evenly.
[0033] In this embodiment, an L-shaped plate is threadedly installed on the bottom of the flat plate 56 by a third bolt, and a brush plate 6 that contacts the filter screen 16 is fixedly installed on the bottom of the L-shaped plate.
[0034] Specifically, the third bolt is screwed into the L-shaped plate and the spreading plate 56, so that the brush plate 6 contacts the filter screen 16.

[0035] The working principle of the above embodiments is as follows:
[0036] The staff opens the silo door and pours rice into the feed hopper 4. The rice falls onto the top of the filter screen 16. Then, the motor 52 is turned on, which drives the threaded rod 53 to rotate. The threaded sleeve 54 drives the moving rod 55 and the spreading plate 56 to move, spreading the rice evenly. Finally, the vibration motor 15 is turned on, causing the housing 14 and the filter screen 16 to vibrate. The spring 12 deforms under pressure, and the filter screen 16 sieves the rice. Impurities pass through the filter screen 16 and fall into the first collection box 22 along the first feed hopper 21. The rice falls into the second collection box 22 along the second feed hopper 23. Inside the collection box 24, the reduced rice accumulation area allows for a larger rice sieving area, improving sieving efficiency. After sieving, the second bolt is first unscrewed from the inside of the cover 3 and the cover 3 is removed. Then, the third bolt is screwed into the L-shaped plate and the spreading plate 56, so that the brush plate 6 contacts the filter screen 16. Then, the motor 52 is turned on, and the motor 52 drives the threaded rod 53 to rotate. The threaded sleeve 54 drives the moving rod 55, the spreading plate 56, and the brush plate 6 to move. The brush plate 6 cleans the filter screen 16, and the remaining rice falls along the second discharge bin 23 into the inside of the second collection box 24, improving cleaning efficiency.
