The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0038] The working principle of the above embodiment is:

[0039] When too many impurities are accumulated inside the filter cloth, the water pump 7 is started to extract the cleaning liquid inside the water storage tank 6 and transport it to the water spray pipe 5, and the cleaning liquid is sprayed on the left and right sides of the filter cloth through the nozzle, and then the servo motor 401 is started. The output shaft of the servo motor 401 rotates and drives the left threaded rod 402 to start rotating. The left threaded rod 402 drives the driving disk 4061 to start rotating during the rotation.

The threaded rod 402 will mesh with the movable block 404 while rotating. Since the number of outer surfaces on the threaded rod 402 is two The thread strips with opposite thread rotation directions make the two movable blocks 404 only be driven to move relative to or away from each other. At the same time, since the two movable blocks 404 are limited by the limit rod 403, the movable blocks 404 can only move vertically up and down. When the movable blocks 404 move, they will drive the clamping blocks 405 to move. During the movement, the clamping blocks 405 drive the nozzles to move up and down reciprocatingly. At this time, the impurities accumulated inside the filter cloth are washed and cleaned, so that the impurities gradually flow out of the filter cloth to the inner bottom wall of the tank body 1, and finally flow out of the outside of the tank body 1 through the drain port 11, completing the cleaning of the filter cloth, achieving the purpose of automatic cleaning, and realizing the continuous use of the filter cloth filter.
