[0027] As a preferred embodiment, the reciprocating brush 3 is provided with a push rod 31, the push rod 31 is directly opposite to the push plate 45, the push rod 31 can push the push plate 45 by being arranged, thereby enabling the connecting rod 44 to move away from the filter screen 2, and the rotating plate 7 is driven to rotate under the cooperation of the sliding block 41 and the guide rail 43, the rotating mode of the rotating plate 7 is that the side away from the filter screen 2 moves upward and the side close to the filter screen 2 moves downward, thereby ensuring that the dirt on the rotating plate 7 can fall into the collecting box 8. The reciprocating brush 3 is power-connected with the electric cylinder 32.

[0028] The working principle of the utility model:

[0029] When the device is used, the water after being settled in the settling tank 9 is first transported into the filter box 1 through a water pipe, and is filtered in the filter box 1 through the filter screen 2, and when filtering, the dirt on the filter screen 2 is removed and pushed onto the rotating plate 7 through the reciprocating brush 3.

[0030] When the reciprocating brush 3 approaches the push plate 45, the push rod 31 pushes the push plate 45, and then the connecting rod 44 moves away from the filter screen 2, and under the cooperation of the sliding block 41 and the guide rail 43, the rotating plate 7 rotates, and the rotating plate 7 rotates and drives the rotating shaft 71 to rotate, the rotating shaft 71 pulls the movable plate 52 to approach the mounting frame 51 through the rope 62, and then ensures that the rotating plate 7 does not jam when rotating. The rotating plate 7 rotates and pours the dirt on the rotating plate 7 into the collecting box 8.

[0031] When the reciprocating brush 3 moves away from the push plate 45, the rotating shaft 71 is reset under the action of the reset spring 42, and under the cooperation of the sliding block 41 and the guide rail 43, and when the rotating plate 7 resets and rotates, the movable plate 52 also pulls the rope to reset under the elastic force of the spring 53.
