[0027] The utility model discloses a primary filter plate 3 and secondary filter plate 71 can carry out twice filtering dust removal to grain, because the aperture of second filter hole 72 is less than the aperture of first filter hole 31, so primary filter plate 3 can filter the impurity of larger volume first, and secondary filter plate 71 can carry out secondary filtering to the impurity of smaller volume, improve the dust removal effect to grain. Because primary filter plate 3 is inclined and is arranged, makes the impurity can use self -gravity and rolls and is accumulated at the impurity discharge gate 5, through the closed mechanism 6 can open the impurity discharge gate 5 to clean up the accumulated impurity conveniently, through the shaking mechanism 4 can accelerate the filtering speed of primary filter plate 3, through the clearing mechanism 8 can carry out the clearing operation to secondary filter plate 71.

[0028] The utility model still includes the dust removal mechanism of drawing away, this dust removal mechanism of drawing away with the structure of the dust removal mechanism in CN221675207U's one kind of grain dust remover is same, its working principle is prior art, no longer carry on here.

[0036] The rack 84 is pushed forward by the electric cylinder 82, the rack 84 drives the gear 85 to rotate, the gear 85 drives the driving rod 83 to rotate synchronously, all the mounting seats 86 also rotate synchronously with the driving rod 83, the knocking stick 87 rotates synchronously with the mounting seat 86, the knocking stick 87 can knock the secondary filter plate 71, the electric cylinder 82 pushes the rack 84 backward, the knocking stick 87 can rotate away from the secondary filter plate 71, so the knocking stick 87 can form a swing to continuously knock the secondary filter plate 71, and the impurities blocked in the second filter hole 72 can be separated.

[0037] One end of all the mounting seats 86 is provided with a groove 88, the knocking stick 87 is fixedly connected in the groove 88 of the mounting seat 86 by bolts, and the knocking stick 87 is installed in the form of bolts, which is convenient for disassembling in use.

[0038] The knocking stick 87 is made of rubber material, which can effectively avoid damaging the secondary filter plate 71 when knocking the secondary filter plate 71, and prolong the service life of the equipment.

[0039] Working principle: in use, first, the grain is poured into the discharging table 1, then the shaking mechanism 4 and the dust removal mechanism are opened synchronously, the shaking mechanism 4 drives the primary filter plate 3 to shake and screen the grain, then the grain falls into the dust removal table 2, then the dust removal mechanism can suck out the smaller impurities, after the work is completed, the impurity discharging port 5 is opened by the closing mechanism 6, so as to take out the impurities retained on the primary filter plate 3, when the secondary filter plate 71 needs to be cleared, the knocking stick 87 of the clearing mechanism 8 knocks the secondary filter plate 71, so that the impurities are separated from the second filter hole 72, and the clearing is completed.
