[0038] When the driving motor 7 is started, the driving rod 18 at its output end rotates. As can be seen from the above content, the driving motor 7 drives the driving rod 18 to reciprocate, and the linkage plate 101 is restricted in the sliding groove 2 and can only move forward and backward, thereby realizing the reciprocating forward and backward displacement of the linkage plate 101 with the outer thread sleeve; and according to the two connecting plates 102 respectively fixedly arranged on both sides of the lower end surface of the linkage plate 101, the lower ends of the two connecting plates 102 are respectively fixedly connected to the two cleaning scrapers 103, and the two cleaning scrapers 103 are respectively connected to the four Two guide rods 15 located on the same side of the guide rods 15 are movably sleeved, and one side of the two top blocks 16 is fixedly provided with a guide block 23, and the two connecting plates 102 are movably sleeved with the two guide blocks 23 respectively; it can be seen that the linkage plate 101 drives the two cleaning scrapers 103 to reciprocate on the guide rods 15 in the front-back direction, and the connecting plate 102 slides forward and backward along the guide block 23, and then the cleaning scrapers 103 perform a surface cleaning operation of scraping off the two filter plates during the movement to reduce the clogging of the mesh of the filter plates;
