Wherein, the fertilizing disc 13 comprises a disc body 24 and a plurality of fertilizing blades 25. A plurality of fertilizing blades 25 are fixed to the circular disk body 24 and are disposed around the center of the plurality of fertilizing blades 25 to divide the surface of the circular disk body 24 into a plurality of fertilizing areas. In the present embodiment, the number of the fertilizing blades 25 is four, and the four fertilizing blades 25 may be integrally formed on the circular disk body 24 or may be individually mounted. The four fertilizing blades 25 are arranged like the fan-shaped arrangement of the impeller, and the aim is to throw the fertilizer out after the fertilizer is subjected to sufficient centrifugal force, so that the spreading surface of the fertilizer is larger, and the fertilizer spreading efficiency and the fertilizer spreading effect are improved.

The gear shaft 15 is mounted on a position adjusting block 16, and the position adjusting block 16 is mounted on the frame 1. The adjusting rod is used for adjusting the distance between the position adjusting block 16 and the other end of the baffle plate 14 so as to adjust the coincidence angle of the fertilizer spreading cover 12 and the fertilizer spreading disc 13.
Referring to fig. 11 and 12, the screw conveyor 17 is rotatably installed in the fertilizer box 2 and is used for spinning to directionally convey the fertilizer in the fertilizer box 2 to the discharge port 3, so that the fertilizer is discharged from the discharge port 3 into the upper disc 10 or the lower disc 11.
