The number of the suction nozzles 8 is multiple and linearly distributed. The multiple suction nozzles 8 are arranged with good dust suction effect. A dust suction pipe 9 is fixedly connected to the front surface of the dust suction plate 7. The dust suction pipe 9 is made of a plastic hose. The plastic hose is provided so that when the height of the dust suction plate 7 changes, the dust suction pipe 9 is not affected. A second support rod 21 is fixedly connected to the front surface of the machine body 1. A second groove 22 is provided inside the second support rod 21. A second slider 23 is slidably connected to the inner surface of the second groove 22. A guide rod 24 is slidably connected to the inner surface of the second slider 23. The guide rod 24 plays a guiding role when the dust suction plate 7 moves. The left surface of the second slider 23 is fixedly connected to the dust suction plate 7. The connection between the second slider 23 and the dust suction plate 7 makes the movement of the dust suction plate 7 more stable.

The second motor 18 is electrically connected to an external power source, and the first motor 4 and the pump body 10 are both electrically connected to an external power source.

[0024] Working principle: When it is necessary to clean the dust on the filter plate 14, start the pump body 10. The dust on the surface of the filter plate 14 enters the dust suction pipe 9 through the suction nozzle 8 and the dust suction plate 7. After passing through the pump body 10 and the connecting pipe 11, it enters the dust collection box 12 for collection. At the same time, start the first motor 4. The output end of the first motor 4 rotates to drive the reciprocating lead screw 5 to rotate. The first slider 6, the dust suction plate 7 and the suction nozzle 8 on the reciprocating lead screw 5 move to clean the dust at different height positions of the filter plate 14. Start the second motor 18 to drive the rotating shaft 19 and the centrifugal block 20 to rotate. The centrifugal block 20 strikes the filter plate 14, and the dust particles stuck in the pores on the filter plate 14 can be knocked out to keep the pores permeable. During the process of striking the filter plate 14, under the action of the spring 15 and the damper 16, the damage caused by the impact on the filter plate 14 can be reduced, and the service life of the filter plate 14 can be extended. This structure can quickly clean and collect the dust on the surface of the filter 14, timely clean the dust on the surface of the filter plate 14, prevent the dust from clogging the pores of the filter plate, ensure that the air can pass smoothly, enable the filter plate 14 to continuously and efficiently play its role, always maintain a good dust-changing effect, and can strike the dust particles on the filter plate 14 to shake out the dust particles blocking the pores, further improving the dust-filtering and dust-changing efficiency of the filter plate.
