The slots 1011 are used to allow the filter plate 1012 to be replaced, thereby adjusting the filtering density and speed.

[0031] In addition, if attached Figure 4 and attached Figure 5 As shown, a bucket 301 is welded to the rear end face of the cleaning piece 3, and protruding strips of flexible material are arranged on the left and right sides of the bucket 301, and the strips are clamped in the inside of the slot 1011, and the rear end bottom edge of the bucket 301 is made of flexible material and fits on the front end face of the filter plate 1012, and a through hole is provided at the bottom of the bucket 301, and a spring telescopic sleeve rod 302 is arranged at the bottom of the cleaning piece 3, and the bottom of the spring telescopic sleeve rod 302 is fixedly connected to the top surface of the fixed base 1, when there is no external restraining force on the top of the cleaning piece 3, the spring outside the spring telescopic sleeve rod 302 pushes the cleaning piece 3 to move upward, and simultaneously drives the bucket 301 to move upward, so as to clean up the debris inside the filter box 101 and avoid blockage.

[0032] In addition, if attached Figure 1 and attached Figure 2 As shown, a lifting rod 401 is fixedly installed on the bottom surface of the top plate 4, and the controller of the lifting rod 401 is electrically connected to the external circuit controller. The bottom end of the push rod of the lifting rod 401 is fastened with a connecting block 402 through a bolt assembly, and the bottom surface of the connecting block 402 is fixedly connected to the top surface of the linkage member 7. When the lifting rod 401 is started to rise and fall through the controller, the linkage member 7 is synchronously driven to rise and fall through the connecting block 402, thereby the pushing position of the cleaning member 3 can be adjusted.
