[0023] Please see Figure 1-4 A pesticide spraying device includes a base plate 1, a support frame 2 fixedly connected to the upper surface of the base plate 1, and an adjustment mechanism 3 provided above the support frame 2.

[0024] The adjustment mechanism 3 includes a limiting frame 301. The bottom surface of the limiting frame 301 is fixedly connected to the upper surface of the support frame 2. A handrail 4 is fixedly connected to the upper surface of the base plate 1. An anti-slip sleeve 5 is fixedly connected to the outer surface of the handrail 4. By setting the handrail 4 and the anti-slip sleeve 5, the device can be easily moved. At the same time, the anti-slip sleeve 5 can prevent the hand from slipping.

[0025] The inner wall of the limiting frame 301 is slidably connected to two moving racks 304. The upper surface of the base plate 1 is fixedly connected to a liquid storage cylinder 9, and the bottom surface of the base plate 1 is fixedly connected to four casters 6. By setting the liquid storage cylinder 9 and the casters 6, the liquid storage cylinder 9 can conveniently store the sprayed pesticides, and the casters 6 can conveniently drive the movement of the device.

[0026] Each movable rack 304 has a spray pipe 303 fixedly connected to its outer surface, and each spray pipe 303 has a guide hose 302 fixedly connected to its outer surface. The upper surface of the storage cylinder 9 is fixedly connected to an injection pipe 7, and a plug 8 is slidably connected to the inner wall of the injection pipe 7. By setting the injection pipe 7 and the plug 8, pesticides can be easily injected into the storage cylinder 9, while the plug 8 can prevent pesticides from splashing out.

[0027] Two servo motors 305 are fixedly connected to the upper surface of the support frame 2. The output end of each servo motor 305 is fixedly connected to a rotating shaft 306. A liquid pump 10 is provided on the outside of the liquid storage cylinder 9. The bottom surface of the liquid pump 10 is fixedly connected to the upper surface of the base plate 1. The input end of the liquid pump 10 passes through the liquid storage cylinder 9 and extends into the interior of the liquid storage cylinder 9. By setting the liquid pump 10, the pesticide inside the liquid storage cylinder 9 can be easily extracted, thereby enabling rapid spraying.

[0028] The outer surface of each rotating shaft 306 is rotatably connected to the inner wall of the limiting frame 301. A gear 307 is fixedly connected to the outer surface of each rotating shaft 306. A three-way pipe 11 is fixedly connected to the output end of the pump 10. The end of the three-way pipe 11 away from the pump 10 is fixedly connected to the end of the guide hose 302 away from the spray pipe 303. By setting the three-way pipe 11, the pesticide can be conveniently transmitted to different directions, thereby improving the spraying efficiency of the pesticide.

[0029] The outer surface of each gear 307 is meshed with the outer surface of the movable rack 304. The outer surface of each servo motor 305 is fixedly connected with a protective cover 12. The bottom surface of each protective cover 12 is fixedly connected with the upper surface of the support frame 2. By setting the protective cover 12, the stability of the servo motor 305 can be further increased, and a certain degree of protection can also be provided.

[0030] The working principle of this utility model is as follows: In use, the operator first connects the power supply to the servo motor 305 and the pump 10 to ensure a stable power supply. Then, the operator removes the plug 8 from the injection pipe 7 and injects an appropriate amount of pesticide into the storage cylinder 9 through the injection pipe 7. After injection, the plug 8 is reset, and the pump 10 is then turned on for spraying. The pump 10 extracts the pesticide from the storage cylinder 9 and transmits it through the three-way pipe 11 to the two guide hoses 302. The guide hoses 302 then transmit the pesticide to the spray pipe 303 for spraying. When it is necessary to adjust the spray coverage area of ​​the spray pipe 303, the operator turns on the servo motor. 305. When the servo motor 305 is turned on, it generates power to rotate. The rotation of the servo motor 305 drives the rotating shaft 306 on the surface to rotate. The rotation of the rotating shaft 306 drives the gear 307 to rotate. When the gear 307 rotates, it can apply a thrust to the moving rack 304, thereby pushing the two moving racks 304 to move outward of the limiting frame 301. At the same time, the movement of the moving racks 304 can drive the spray pipe 303 on the surface to adjust and move, thereby adjusting the distance between the two spray pipes 303. This allows for easy changes to the overall spray coverage area of ​​the device. Furthermore, when the spray pipe 303 moves, it can pull the guide hose 302 to move. The guide hose 302 can conveniently assist the spray pipe 303 in moving and adjusting.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
