In embodiment 3, since the rotating shaft 8 drives the first shielding cover 17 to rotate, under the action of inertia, the powder falling on the first shielding cover 17 is thrown off by the rotating first shielding cover 17, so that the powder of the ground solid reagent-producing raw material raised up is not easily accumulated on the first shielding cover 17, but the second shielding cover 21 is fixed, and the powder of the ground solid reagent-producing raw material raised up is very easily accumulated on the upper surface of the second shielding cover 21. referring to fig. 1, 3, 4 and 5, as another preferred embodiment of the present invention, the difference from embodiment 3 is that a striking mechanism is provided inside the fixed cylinder 20, the striking mechanism includes a first bevel gear 24, the first bevel gear 24 is coaxial with the axis and penetrates through the rotating shaft 8 fixed inside the fixed cylinder 20, all be equipped with the transfer line 26 on the perpendicular and rotation of the fixed cylinder 20 inside wall of first bevel gear 24 both sides, it is equipped with second bevel gear 25 with the axle center is fixed on the transfer line 26 top, two second bevel gears 25 all mesh with first bevel gear 24 each other, it is equipped with cam 27 to go up the perpendicular and fixed running through on the transfer line 26, the fixed pole 30 that is equipped with on the fixed cylinder 20 inside wall of transfer line 26 top is fixed perpendicularly, it is equipped with spacing cylinder 28 to fix perpendicularly on the fixed pole 30 top, it has movable rod 29 to insert with the axle center and slip in the spacing cylinder 28, and movable rod 29 both ends contact with the highest point department of second shielding cover 21 lower surface and cam 27 respectively. Since the second shielding cover 21 is fixed, the powder of the ground solid reagent production raw material that is lifted up is very easily accumulated on the upper surface of the second shielding cover 21, the motor 7 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the first bevel gear 24 to rotate, the first bevel gear 24 drives the second bevel gears 25 at both sides to rotate, the second bevel gears 25 rotate to drive the transmission rod 26 to rotate, the transmission rod 26 rotates to drive the cam 27 to rotate, and since the moving rod 29 and the limiting cylinder 28 are slidably inserted, the bottom end of the moving rod 29 is always in sliding contact with the circumferential surface of the cam 27 under the action of gravity, under the action of the rotating cam 27, the moving rod 29 moves up and down in the limiting cylinder 28, and when the moving rod 29 rises to the highest position in the limiting cylinder 28, the moving rod 29 strikes the second shielding cover 21, and since the second shielding cover 21 and the second shielding cover 21 are accumulated, the material of the powder of the ground solid reagent production raw material that is lifted up is easily accumulated on the second shielding cover 21 Different, so under the knock of the moving rod 29, the amplitude of the lifted ground raw material for producing solid reagents accumulated on the second shielding cover 21 and the amplitude of the second shielding cover 21 may be different, and then the frequency of the lifted ground raw material for producing solid reagents accumulated on the second shielding cover 21 and the frequency of the second shielding cover 21 may also be different, so that the lifted ground raw material for producing solid reagents accumulated on the second shielding cover 21 is not easily accumulated on the second shielding cover 21.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
