Because the high-pressure airflow is stored in the pneumatic groove 405 at this time, when the rotating seat 404 rotates to the direction of the telescopic air outlet pipe 501, the high-pressure airflow in the pneumatic groove 405 flows to the telescopic air outlet pipe 501, and flows to the fixed air pipe 503 through the connecting air pipe 502.

The air pump 13 draws air and filters the dust inside the shell 1 through the filter box 12. The air pump 13 blows the high-pressure airflow into the pneumatic shell 401 through the air inlet pipe 402. The high-pressure airflow blows the rotating seat 404 through the pneumatic groove 405.

At the same time, the air flow flows out of the blowing groove 506 to blow up the dust on the gangue and the inner wall of the shell 1, and the dust collection head on the filter box 12 filters the dust. As the air pressure in the blowing groove 506 is released, the knocking spring 508 pulls the guide column 505 to reset, and pulls the knocking ball 507 back into the blowing groove 506, reciprocatingly knocking on the multi-stage screening frame 2, reciprocatingly blowing up the dust, and removing the gangue.
