In order to prevent the filter hole from being blocked and affecting the collection of impurities, a cleaning plate is set on one side of the filter hole. The cleaning plate slides elastically inside the guide groove by the second return spring. When the shaft rotates, the cooperation of the locking block, the spiral groove and the connecting groove regularly drives the limiting shaft to compress the fourth air storage bag. The gas inside the airbag is regularly discharged into the third air reservoir through the third exhaust pipe. The third air reservoir expands and regularly pushes the cleaning plate down along one side of the guide groove. The downward movement distance squeezes the compression plate, which in turn compresses the first air reservoir. The gas inside the first air reservoir is discharged into the second air reservoir through the first exhaust pipe. The second air reservoir expands and pushes the holding rod to extend, pushing the cleaning plate from one side of the guide groove into the other side. Then, the second reset spring pulls the cleaning plate back to its original position. During the pulling process, the cleaning plate cleans the impurities on the surface of the filter holes.

Cleaning of filter holes (14): To prevent filter holes (14) from being blocked and affecting the collection of impurities, a cleaning plate (18) is set on one side of filter holes (14). The cleaning plate (18) slides elastically inside the guide groove (19) through the second return spring (20). When the rotating shaft (9) rotates, the limiting shaft (39) is regularly driven to compress the fourth air storage bag (38) through the cooperation of the locking block (40), the spiral groove (42) and the connecting groove (43). The gas inside the fourth air storage bag (38) is regularly discharged into the third air storage bag (34) through the third exhaust pipe (36). The third air storage bag (34) expands. The cleaning plate (18) is pushed down along one side of the guide groove (19) in a regular manner. The downward movement distance squeezes the squeezing plate (23). The squeezing plate (23) compresses the first air storage bag (22). The gas inside the first air storage bag (22) is discharged to the second air storage bag (28) through the first exhaust pipe (24). The second air storage bag (28) expands, pushing the support rod (26) to extend and pushing the cleaning plate (18) from one side of the guide groove (19) into the other side of the groove. Then, the cleaning plate (18) is pulled back to its original position by the second reset spring (20). During the pulling process, the cleaning plate (18) cleans the impurities on the surface of the filter hole (14).
