Then loosen the locking bolt. Under the self-weight of the pull rod 10-7 and the rotating rod 11-1, the quantitative sleeve plate 11-2 moves down to an appropriate position. Then tighten the locking bolt so that the locking bolt abuts against the rubber pad 11-4. Start the driving motor 11-5. The driving motor 11-5 drives the quantitative inserting plate 11-3 to rotate. The quantitative inserting plate 11-3 drives the quantitative sleeve plate 11-2 to rotate. During the rotation of the quantitative sleeve plate 11-2, it drives the pull rod 10-7 to move up and down through the rotating rod 11-1. The pull rod 10-7 drives the piston plate 10-4 to move up and down through the connecting frame 10-6. When the piston plate 10-4 moves upward, it makes the upper sealing cover 10-5 abut against the piston plate 10-4 through negative pressure, and the lower sealing cover 10-5 rotates upward to an open state. At this time, the fertilizers in the fertilizer tank 1 are pumped into the conveying pipe 10-1.When the piston plate 10-4 moves downward, the sealing cover 10-5 on the lower side is closed, while the sealing cover 10-5 on the upper side is opened. Fertilizer inside the conveying pipe 10-1 flows through the through hole 10-4-1 at the center of the piston plate 10-4 to the upper side of the piston plate 10-4. During the reciprocating movement, the fertilizer passes through the feeding pipe 10-3, enters the connecting block 6, and finally is discharged through the three discharging pipes 5 to achieve the effect of fertilization.

[0032] Compared with the prior art, the beneficial effects of the present specific embodiment are as follows: 1. The connecting block 6 on the upper side of the discharging pipe 5 for fertilization can be adjusted by the distance adjusting mechanism 9, so that the three discharging pipes 5 can be equidistant and adjusted in distance to meet the use of crops at different distances; 2. The piston method is adopted to convey the fertilizer, and the distance of the up and down movement of the piston can be adjusted by the metering mechanism 11, so as to achieve the effect of metered fertilization; 3. A stirring mechanism 12 is arranged inside the fertilizer tank 1, and the stirring mechanism 12 is connected to the connecting shaft 15. The stirring mechanism 12 can be driven during the movement of the fertilizer tank 1, so as to achieve the stirring effect; 4. When the stirring mechanism 12 is stirring, the stirring rod 12-5 inside the stirring mechanism 12 can be driven by the reciprocating mechanism 12-8 to reciprocate up and down, thereby improving the stirring effect.
