The invention discloses a
fertilizer applying device for green crisp plums. The
fertilizer applying device comprises a supporting plate, hand shanks are both arranged at the two sides of the supporting plate, a rolling bearing penetrates through the supporting plate, a motor is further arranged on the supporting plate, a motor is connected with a small gear, and the small gear is meshed with a biggear; a hollow rotary shaft is connected to the inside of the rolling bearing, the upper end of the hollow rotary shaft is connected to the inside of a center hole of the big gear, and a leaking holeis formed in the side wall of the hollow rotary shaft; a drilling head is connected to the bottom of the hollow rotary shaft, a
spiral blade is arranged on the hollow rotary shaft, and the lower endof the
spiral blade is located at the junction of the drilling head and hollow rotary shaft; a flow guiding
pipe is arranged inside the hollow rotary shaft, the outer wall of the flow guising
pipe closely fits the inner wall of the hollow rotary shaft, and a material box is arranged on the upper end of the flow guiding
pipe; a through hole is formed in the bottom of the material box and is communicated with the flow guiding pipe, a control valve is arranged on the flow guiding pipe, the control valve is located between the material box and the big gear, and an air cylinder used for controllinglifting and lowering of the material box is arranged on the supporting plate. When the
fertilizer applying device is adopted to apply fertilizer to the green crisp plums, damage to green crisp plum roots can be effectively reduced.
