When the fertilizer is distributed, the fertilizer is directly discharged from the discharge nozzles near the middle position, and the amount of fertilizer discharged from the discharge nozzles at both ends is less, resulting in uneven fertilization.

[0013] When the distribution roller rotates to the state that the distribution groove faces upward, the fertilizer enters the distribution groove, and when the distribution roller rotates to the state that the distribution groove faces downward, the fertilizer drops into the discharge nozzle, and the fertilizer is filled in the distribution cavity, so that the fertilizer can fill each distribution groove on the distribution roller when the distribution groove faces upward, and then the fertilizer in each distribution groove is discharged from the discharge nozzle when the distribution groove faces downward, so that the amount of fertilizer discharged from each discharge nozzle is the same, thereby achieving the effect of uniform fertilization.

[0014] Preferably, the moving assembly further comprises walking wheels installed on both sides of the vehicle body, and one end of the vehicle body is connected with one end of the agricultural machine through a connecting arm, so that the moving assembly can walk on the wheat field.
