By controlling the electric push rod 12 to control the dosage of the medicine entering the liquid storage tank 5, accurate application of medicine can be achieved. By accurately controlling the application amount, the waste of pesticides can be reduced and the utilization rate of pesticides can be improved.

[0022] An atomizing nozzle is arranged at the bottom of the nozzle group 11. The rotating atomizing nozzle can evenly distribute the medicine in the target area to avoid accumulation or loss of the medicine in certain areas, which helps to improve the effect of the medicine and reduce waste. The surface of the fixed frame 13 close to the sliding frame 14 is set as an inclined surface.

[0023] When the present embodiment is working, by adding medicine into the liquid inlet 4, the medicine enters the infusion tube 3, and the output end of the electric push rod 12 moves to drive the fixed frame 13 to move. The inclined surface of the fixed frame 13 moves to contact the arc surface of the sliding frame 14, so that the sliding frame 14 moves upward, and the movement of the sliding frame 14 drives the sliding rod 15 to move. The movement of the sliding rod 15 drives the sealing plug 16 to move. At this time, the medicine in the infusion tube 3 will flow into the liquid storage tank 5.

The rotation of the nozzle group 11 drives the atomizing nozzle to rotate, so that the medicine is sprayed out from the atomizing nozzle. The rotating atomizing nozzle can make the medicine evenly distributed in the target area to avoid accumulation or loss of medicine in certain areas, which helps to improve the effect of the medicine and reduce waste.

[0024] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a stirring device and a cleaning device are arranged inside the liquid storage tank 5, and the stirring device includes a wave-breaking plate 20, a rotating motor 21 and a screw 22. The wave-breaking plate 20 is fixedly mounted on the bottom of the sliding rod 15, and the fixed end of the rotating motor 21 is fixedly mounted on the bottom of the liquid storage tank 5. The screw 22 is fixedly mounted on the output end of the rotating motor 21. The circumferential surface of the screw 22 is provided with a reciprocating spiral groove.

[0025] The stirring device also includes a stirring blade 23, a stirring rod 24 and a connecting frame 25. The stirring blade 23 is fixedly installed on the circumferential surface of the screw rod 22. The stirring blade 23 is used to mix the medicine in the liquid storage tank 5 to prevent the medicine from precipitating in the liquid storage tank 5. It can also improve its fluidity, making it easier to transport and spray the medicine through the spraying system of the plant protection drone. This can reduce the blockage and waste of the medicine during the transportation process and improve the utilization rate of the medicine. The stirring rod 24 is slidably installed on the circumferential surface of the screw rod 22. The stirring rod 24 is threadedly connected to the reciprocating spiral groove. The stirring rod 24 moves so that the medicine precipitated at the bottom of the inner wall of the liquid storage tank 5 is stirred into the working range of the stirring blade 23. The connecting frame 25 is fixedly installed on the top of the screw rod 22.

[0026] The cleaning device includes a gear block frame 30, a fixing button 31 and a gear 32. The gear block frame 30 is fixedly installed on the inner wall of the liquid storage tank 5, the fixing button 31 is fixedly installed on the bottom of the connecting frame 25, and the gear 32 is rotatably installed on the bottom of the fixing button 31.

[0029] The blocking plate 35 is in contact with the liquid storage tank 5 , and a No. 1 spring is arranged between the limiting rod 37 and the fixing block 36 , so that the limiting rod 37 is driven to reset by the arranged No. 1 spring.

[0030] When the present embodiment is working, the movement of the slide bar 15 drives the wave-breaking plate 20 to move. The setting of the wave-breaking plate 20 can effectively reduce the shaking of the liquid in the infusion tube 3, reduce the change of the center of gravity, make the UAV more stable during flight, and reduce the flight deviation and risk of loss of control caused by shaking. The output end of the rotating motor 21 rotates to drive the screw rod 22 to rotate, and the screw rod 22 rotates to drive the stirring blade 23 to rotate. The stirring blade 23 mixes the medicine in the liquid storage tank 5 to prevent the medicine from precipitating in the liquid storage tank 5, and improves its fluidity, making it easier to transport and spray through the spraying system of the plant protection UAV. This can reduce the blockage and waste of the medicine during transportation and improve the utilization rate of the medicine. The rotation of the screw rod 22 also drives the rotation of the reciprocating spiral groove, and also drives the rotation of the connecting frame 25. The rotation of the reciprocating spiral groove causes the stirring rod 24 to reciprocate up and down, and the movement of the stirring rod 24 causes the medicine precipitated at the bottom of the inner wall of the liquid storage tank 5 to be stirred into the working range of the stirring blade 23. The rotation of the connecting frame 25 drives the fixing button 31 to rotate, and the rotation of the fixing button 31 drives the gear 32 to move. The movement of the gear 32 will contact the tooth block frame 30 to make the gear 32 rotate. The rotation of the gear 32 drives the round rod 33 to rotate, and the rotation of the round rod 33 drives the scraper 34 to rotate. The rotation of the scraper 34 allows the medicine remaining on the inner wall of the liquid storage tank 5 to be cleaned. Cleaning the medicine remaining on the inner wall of the liquid storage tank 5 can reduce the corrosion and wear of the medicine on the equipment, thereby extending the service life of the equipment. If there are too many medicine residues, it may cause equipment damage and increase maintenance costs. After cleaning, the blocking plate 35 is disengaged from the restriction of the limiting rod 37 by moving the limiting rod 37 upward. The blocking plate 35 is prevented from being accidentally touched by the limiting rod 37 to prevent the medicine from being spilled and wasted due to accidental touching by external force. The movement of the blocking plate 35 allows the sewage in the liquid storage tank 5 to flow out, so as to facilitate further processing by the operator.
