The block 12 is fixedly connected to the upper surface of the support plate 306, and the support plate 306 drives the block 306 to move.

[0022] The lifting mechanism 3 includes a screw rod 301, a threaded block 302, a wedge block 303, a roller 304, a support rod 305, a support plate 306, a sliding rod 307, a sleeve 308 and a spring 309. The outer walls of both ends of the screw rod 301 are rotatably connected to the frame 5 through bearings. The outer wall of the screw rod 301 is threadedly connected with the threaded block 302. The screw rod 301 drives the threaded block 302 to move. The upper part of the threaded block 302 is fixedly connected with the wedge block 303. The threaded block 302 drives the wedge block 303 to slide. The outer wall of the wedge block 303 is slidably connected to the frame 5. The outer wall of the wedge block 303 fits with the roller 304. The wedge block 303 drives the roller 304 to move. The roller 304 is rotatably connected to the support rod 305 through a pin shaft. The roller 304 drives the support rod 305 to move.

[0023] The upper end of the support rod 305 is fixedly connected with a support plate 306, and the support rod 305 drives the support plate 306 to move. A sliding rod 307 is fixedly connected below the support plate 306, and the support plate 306 drives the sliding rod 307 to move.

[0025] The anti-sway mechanism 4 includes a slide groove 401, a slider 402, a plastic plate 403, a through hole 404 and a foam plate 405. The slide groove 401 is arranged inside the tank body 2. The slide groove 401 is slidably connected to the slider 402 inside. The slider 402 slides inside the slide groove 401. The slider 402 is fixed to the outer wall of the plastic plate 403. The slider 402 and the plastic plate 403 move together. The slide groove 401 and the slider 402 guide the movement of the plastic plate 403. The plastic plate 403 is provided with a through hole 404 inside. The through hole 404 facilitates the passage of pesticides. The lower surface of the plastic plate 403 is fixed with a foam plate 405. The foam plate 405 increases the buoyancy of the plastic plate 403 in the tank body 2, so that the plastic plate 403 floats above the pesticides.

[0026] Pesticide is added into the tank body 2, and the pesticide reaches the bottom of the plastic plate 403 through the through hole 404. As the pesticide is added, the foam plate 405 and the plastic plate 403 move upward and always float above the pesticide. The plastic plate 403 drives the slider 402 to move, and the slider 402 slides inside the slide groove 401. The slider 402 and the slide groove 401 guide the movement of the plastic plate 403. As the pesticide is sprayed, the pesticide inside the tank body 2 gradually decreases, and the foam plate 405 and the plastic plate 403 always float on the upper surface of the pesticide. When the vehicle body 1 shakes during the movement, the pesticide inside the tank body 2 shakes, and the pesticide contacts the plastic plate 403 during the shaking. The plastic plate 403 reduces the amplitude of the shaking of the pesticide, so that the vehicle body 1 is relatively stable during movement, thereby reducing the difficulty of personnel in controlling the pesticide spraying vehicle.

[0027] Working principle:

[0028] When using the pesticide spraying vehicle to spray pesticides on crops, a battery is installed on the vehicle body 1 to power the liquid pump 7, the cap 6 is unscrewed, and pesticides are added to the inside of the tank body 2. The pesticides reach the bottom of the plastic plate 403 through the through hole 404. As the pesticides are added, the foam plate 405 and the plastic plate 403 move upward and always float above the pesticides. The plastic plate 403 drives the slider 402 to move, and the slider 402 slides inside the slide groove 401. The slider 402 and the slide groove 401 guide the movement of the plastic plate 403.

[0029] Height adjustment stage of the nozzle:

[0030] The staff pushes the pesticide spraying vehicle to the designated position. When the height of the spray head 11 needs to be adjusted according to the actual use requirements, the screw rod 301 is rotated, the screw rod 301 drives the threaded block 302 to move, the threaded block 302 drives the wedge block 303 to slide, the wedge block 303 drives the roller 304 to move, and the height of the roller 304 changes in the vertical direction during the movement. The roller 304 drives the support rod 305 to move, the support rod 305 drives the support plate 306 to move, the support plate 306 drives the block 12 to move, the block 12 drives the hollow tube 10 to move, and then drives the spray head 11 to move, and the height of the spray head 11 is adjusted. After the spray head 11 is adjusted to the required height, the screw rod 301 is stopped. When in use, it is convenient to adjust the height of the spray head 11 according to the use requirements.

[0031] Pesticide spraying stage:

[0032] Start the liquid pump 7, which extracts the pesticide from the tank body 2 and pumps the pesticide into the hollow tube 10 through the hose 8 and the pipe 9, and finally sprays it out from the nozzle 11 to spray the crops. The personnel push the vehicle body forward. As the pesticide is sprayed, the pesticide in the tank body 2 gradually decreases. The foam board 405 and the plastic board 403 always float on the upper surface of the pesticide. When the vehicle body 1 shakes during movement, the pesticide in the tank body 2 shakes. When shaking, the pesticide contacts the plastic board 403, and the plastic board 403 reduces the amplitude of the shaking of the pesticide, so that the vehicle body 1 is relatively stable during movement, thereby reducing the difficulty of personnel in controlling the pesticide spraying vehicle.
