The starter motor 210 drives the turbine 220 to rotate to generate airflow inside the wind chamber 120, and a negative pressure is created at the opening of the air inlet 310. When the turbine 220 rotates, it drives the second rotating rod 230 and the second bevel gear 231 to rotate. The second bevel gear 231 drives the first bevel gear 151 and the reciprocating threaded rod 150 to rotate. The first pulley 152 rotates following the reciprocating threaded rod 150. The first pulley 152 drives the second pulley 172 and the rotating rod 170 to rotate, and then drives the turning plate 171 to rotate, so as to turn and stir the coal inside the receiving tank 110 and raise the dust in the coal. At the same time, when the reciprocating threaded rod 150 rotates, the screw structure is used to push the guide plate 320 to drive the movable plate 300 and the air inlet 310 to move back and forth inside the receiving tank 110, and the dust at the position where the air inlet 310 passes is sucked into the hose 311 from the air inlet 310 and transported to the inside of the dust collecting tank 410 through the wind chamber 120 and the connecting pipe 130.
