The use of the two synchronous dust suction locations and the covering of the top with the cover plate 5 facilitates the integrated and stable dust removal during screening, reduces the phenomenon of large amounts of debris and dust floating outward, and improves the environmental protection effect.

[0036] After use, the cover plate 5 is turned upward to open it, and then the two pull rings 301 can be pulled upward to drive the filter plate 3 to move out, so as to drive the large particles of shrimp feed to move out upward, and the small particles of shrimp feed can be removed by directly moving the receiving box 100 forward, so as to facilitate the quick removal of shrimp feed after screening.
