a2, a driving motor (31) is utilized to drive a first bevel gear (32) to rotate, the first bevel gear (32) can drive a second bevel gear (34) to rotate, so that a transmission sleeve (35) synchronously rotates, namely, a T-shaped transmission rod (315) can be driven to synchronously rotate, and therefore, the rotation of the T-shaped transmission rod (315) can drive a first umbrella-shaped material carrying disc (311) to rotate on the top end face of a second support sleeve (313), so that the thrown wheat particles are conveniently dispersed, and the impurity removal operation is facilitated;
a3, starting the air blower (21), guiding air into an inner cavity of the annular hollow air guiding box (22) through a connecting pipe (24) of the air blower (21), guiding the air in the inner cavity of the annular hollow air guiding box (22) into an inner cavity of the shell (1) through a plurality of air blowing pipes (23) which are distributed annularly, and enabling blown-up wind energy to enter a plurality of second supporting sleeves (313) and a first supporting sleeve (37) until iron and dust removal operations are finished, wherein a plurality of guide holes (314) which are distributed annularly and uniformly at intervals are formed in the radial side wall of each second supporting sleeve (313);
a4, the spring (316) is compressed by pressing the first umbrella-shaped material carrying disc (311) downwards, the T-shaped transmission rod (315) slides along the inner cavity of the inverted T-shaped sliding groove, the first umbrella-shaped material carrying disc (311), the second umbrella-shaped material carrying discs (310) and the umbrella-shaped rubber material carrying discs (38) are all adjusted downwards in height, the umbrella-shaped rubber material carrying discs (38) are supported by the connecting rods (39), the umbrella-shaped rubber material carrying discs (38) are pressed into conical structures with inverted main view cross sections from the conical structures with the upright main view cross sections along with the continuous pressing process, then the iron metal particles adsorbed and screened by the circuits of the electromagnets at the ports can fall into the umbrella-shaped rubber material carrying discs (38) pressed into the conical structures with inverted main view cross sections, slide into the inner cavity of the first supporting sleeve (37) through the material guide holes (314), and finally are discharged through the waste discharge holes.
