The motor 1 drives the rotating rod 8 to rotate, and then drives the filter screen cylinder 9 to rotate through the fixing rod 10. Thus, debris can adhere to the inner wall of the filter screen cylinder 9. The rotation of the rotating rod 8 will drive the spiral blades 11 to rotate. Thus, the debris in the filter screen cylinder 9 can be pushed from the filter screen cylinder 9 onto the guiding hopper 15, and then conveyed into the collection box 16 through the guiding hopper 15. The residual sewage in the debris can be filtered through the filter screen plate 17 and flow out through the water flow port 18, and then discharged through the drain pipe 6. Subsequently, by directly pulling the handle on one side of the cleaning plate 5, the rubber socket plate 13 can be separated from the cleaning opening 12. Then, under the action of the pulling groove 19 and the pull rod 20, the collection box 16 can be pulled out, so that the debris collected inside the collection box 16 can be emptied and cleaned, which is convenient for the staff to quickly clean the collected debris. After cleaning, the collection box 16 can be reinstalled in the fixed cover 14 under the action of the limit sliding plate 22 and the limit sliding frame 21, and then the rubber socket plate 13 is sleeved and connected with the cleaning opening 12, thus completing the installation.
