As shown in FIG. 3 , FIG. 4 and FIG. 5 , the second baffle plate 92 and the third baffle plate 93 are located at the front side of the first baffle plate 91 (ie, the right side in FIGS. 3 and 4 ) in the clockwise direction. During work, start the first motor, the second motor 3, the first blower fan and the second blower fan, the material is put into the housing 1 from the feed port 6, and the material first passes through the turning roller 10 in the falling process, and the hook rod on the turning roller 10 Hook long strips of fibers such as woven bag residues in the material to prevent fibrous impurities from continuing to fall. Then when the material falls through the adsorption roller 12, under the action of the permanent magnet 13, the iron impurities are adsorbed on the outer surface of the adsorption roller 12 and rotate with the adsorption roller 12. When the iron impurities rotate to the gap of the permanent magnet 13 with the adsorption roller 12 position, the gravitational force disappears, and the iron nail impurities fall into the iron impurity storage bin 14, and the material continues to fall. At this time, small and light impurities are sucked out by the negative pressure produced by the second blower fan.

The material continues downward, passes through the discharge port 7, and then enters the drum 9 through the deflector 81. When the drum 9 rotates at a high speed (the first preset speed), the material will cling to the first baffle plate 91 and gather at the second baffle plate 92 and the third baffle plate 93. When the speed of the drum 9 is adjusted to a low speed (the first preset speed) Two preset speeds), the material moves to the right side (the right side in Fig. 3 and Fig. 4 ) relative to the second baffle plate 92 and the third baffle plate 93 by its own inertia and falls, and at the same time, because the speed of the material decreases, the wind force overcomes the material The centrifugal force makes the grain move to the first air-inducing pipe 8, and finally discharges into and out of the material pipe 95. At this time, because the quality of the stone is relatively large relative to the grain, the wind force cannot overcome the centrifugal force of the stone, so the stone will move along the inner wall of the drum 9. Sliding, and finally falling into the stone storage bin 94 for collection.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
