[0023] When rotating and spraying, first, the motor 1 402 drives the gear 1 403 to rotate, the gear 1 403 drives the gear 2 404 to rotate, the gear 2 404 drives the connecting pipe 405 to rotate, the connecting pipe 405 drives the liquid collecting box 406 and the turntable 407 to rotate, so as to drive the two spraying pipes 408 to rotate.

[0024] To improve the stability of the liquid collection box 406 during rotation, a fixing ring located on the outer surface of the connecting pipe 405 is provided at the bottom of the fixing plate 401. The connecting pipe 405 can rotate within the fixing ring. Two grooves are formed at the bottom of the fixing plate 401. Two pulleys slidably connected to the grooves are fixedly installed at the top of the liquid collection box 406. When the liquid collection box 406 rotates, it drives the two pulleys to slide within the two grooves.

[0025] The adjusting mechanism 5 includes a second motor 501. The second motor 501 is fixedly installed on the front inner wall of the turntable 407. A third gear 502 is fixedly installed at the output shaft of the second motor 501. Two fourth gears 503 are meshed with the outer surface of the third gear 502. Sleeve 504 is fixedly installed on each of the two opposite sides of the fourth gears 503. A lead screw 505 is threadedly connected to the outer surface of each of the two sleeves 504.

[0030] To enable the connecting pipe 405 to rotate smoothly, the connecting pipe 405 and the liquid delivery pipe are connected through a rotary joint, and the liquid delivery pipe is a corrugated pipe.

[0031] The lifting assembly 3 includes an electric push rod 301 and a slider 302. Under the action of the lifting assembly 3, it can drive the fixing plate 401 to move up and down, thereby driving the two spraying pipes 408 to move up and down and changing the spraying height.

[0032] A power source is provided on the top of the mobile vehicle 1. The power source supplies power to the device, and a controller is provided on the power source. The liquid suction pump 7, the rotating mechanism 4, and the adjusting mechanism 5 are started through the controller.

[0033] During implementation, the following steps are carried out for operation:

[0034] 1) First, the pesticide in the liquid storage tank 6 is introduced into the liquid collection box 406 through the liquid suction pump 7. The liquid medicine in the liquid collection box 406 enters the two spraying pipes 408 through two introduction pipes.

[0035] 2) Then, the spraying pipe 408 is adjusted to a suitable height through the lifting assembly 3 according to the height of the crops.

[0036] 3) Then, the two spraying pipes 408 are driven by the rotating mechanism 4 to rotate and spray.

[0037] 4) Finally, the number of nozzles that can discharge liquid is adjusted through the adjusting mechanism 5 to reduce the amount of pesticide spraying.

[0038] In summary, for this pesticide spraying device that is easy to adjust, by setting up the spraying device, under the action of the rotating mechanism 4, the two spraying pipes 408 can rotate and spray, improving the spraying range and the uniformity of spraying at the same time. Under the action of the adjusting mechanism 5, the two sealing blocks 506 can move left and right in the corresponding spraying pipes 408, thereby changing the liquid inlet space in the spraying pipes 408 and adjusting the number of nozzles that can be sprayed. It can be flexibly adjusted according to the pesticide spraying requirements of different spraying areas and different crops, achieving the purpose of conservation.
