The gas is discharged from the gas outlet of the vacuum module 5 after being processed by the processing box 4, and enters the interior of the cylinder 706 through the air pipe and acts on the driving page 707, so that the driving page 707 drives the curved rod 701 on the left to start rotating, and under the action of the first pulley group 702, the other group of curved rods 701 starts to rotate synchronously, and the two groups of rotating curved rods 701 will drive the telescopic top rod 703 movably connected on the surface to start moving and push the strip plate 704 to intermittently rise and fall inside the hollow shell 6, and the intermittently rising strip plate 704 will drive the flapping plate 705 to synchronously move to intermittently flap the flexible conveyor belt 2 and lift it up, so that the flexible conveyor belt 2 drives the grain on the surface to vibrate, and vibrates the dust to the grain surface and the air, so that it can be sucked by the suction port; During the process of the flapping plate 705 intermittently flapping the flexible conveyor belt 2, the gas acting on the driving page 707 will enter the cavity 7011 after being compressed by the conical mouth 7021, and will be ejected by the nozzle 806 through the air outlet pipe 7012 and the connecting pipe 7013 and act on the surface of the grain. At the same time, under the action of the rotation of the right curved rod 701, the second pulley group 801 begins to rotate synchronously, so that the half gear 802 drives the tooth plate 803 to move horizontally and compress the connecting spring. The horizontally moving tooth plate 803 will drive the nozzle 806 installed on the vertical plate 805 to move synchronously through the straight rod 804, thereby increasing the blowing area, so that impurities on the surface of the grain are blown up and absorbed, thereby improving the impurity removal efficiency, reducing the pollution of dust to the environment, and ensuring the health of the staff.
