[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers.

[0003] At present, drones for spraying pesticides have been widely used in agricultural production. During the process of existing drones spraying pesticides, the spraying tube is relatively fixed and inconvenient to fold and unfold. Therefore, the spraying area is relatively small during use, and a large space is required for storage. The spraying efficiency is low during use and the storage takes up a lot of space. Therefore, it is necessary to propose a biological pesticide spraying equipment to solve the above problems. Utility Model Content

[0025] See also Figure 1 and Figure 2A spray box 110 and a support leg 120 are installed at the bottom of the drone body 100. The support leg 120 is located on both sides of the spray box 110. A plurality of injection holes are formed on both sides of the spray box 110. Sealing covers are threadedly installed on the injection holes for adding medicines.

[0026] See also Figure 1-Figure 5 The spraying structure 200 includes a spraying driving component 210, two main pipes 220 and an extension pipe 250. The spraying driving component 210 is installed between the spray box 110 and the two main pipes 220. The two main pipes 220 are installed on the sides of the supporting legs 120. The two ends of the main pipes 220 are installed with a fixing frame 230 and a fixing component 240. The fixing component 240 is located on both sides of the fixing frame 230. The extension pipe 250 is rotatably connected to the fixing frame 230. The extension pipe 250 is connected to the main pipe 220 through a hose 251. Limiting columns 253 are fixed on both sides of one end of the extension pipe 250. The fixing component 240 is clamped on the limiting columns 253. Spray heads 260 are evenly installed on the main pipe 220 and the extension pipe 250.

[0027] The spray drive 210 includes a medicine pump 211 and a connecting pipe 214. The medicine pump 211 is installed on the surface of the spray box 110. The output end of the medicine pump 211 is connected to the liquid outlet pipe 212. The liquid inlet of the medicine pump 211 is connected to the spray box 110 through the liquid inlet pipe 213. The two sides of the liquid outlet pipe 212 are connected to the main pipe 220 through the connecting pipe 214. Here, through the setting of the spray drive 210, the medicine inside the spray box 110 can be conveniently transported to the inside of the main pipe 220.

[0028] The surface of the main pipe 220 is fixed with an elastic clip 221 matching the extension pipe 250, and the extension pipe 250 is clamped on the elastic clip 221. The setting of the elastic clip 221 can clamp and fix the extension pipe 250 when it is folded, thereby improving the stability after folding. The fixing member 240 includes a sleeve 241 and a movable column 242. The movable column 242 slides through the interior of the sleeve 241. A movable plate 244 is fixed to one end of the movable column 242. The movable plate 244 is slidably connected to the inner surface of the sleeve 241. A hook 243 is fixed to the other end of the movable column 242. The hook 243 is clamped on the limit column 253. The other end of the sleeve 241 is fixed to the main pipe 220 through the connecting portion 246. The connecting portion 246 includes a first connecting plate 2461 and a connecting column 2462. The first connecting plate 2461 is fixed to the end of the sleeve 241, and the connecting column 2462 is fixed to the main pipe 220. The first connecting plate 2461 is rotatably connected to the connecting column 2462. Here, the movable plate 244 is squeezed against the spring 245 by pulling the hook 243, and the hook 243 is hung on the limiting column 253. In this way, the stability of use can be improved after the extension tube 250 is unfolded.

[0029] A second connecting plate 252 is fixed on the extension tube 250, and the second connecting plate 252 is rotatably connected to the fixing frame 230; a plug-in column 254 is fixed to one end of the extension tube 250, and slots matching the plug-in column 254 are formed at both ends of the main tube 220, and the plug-in column 254 is plugged into the inside of the slot. Here, the plug-in column 254 is plugged into the inside of the slot, and the extension tube 250 is further fixed by the fixing member 240, which can provide stability during use.

[0030] Specifically, the working principle of the biological pesticide spraying device is as follows: when in use, the extension tube 250 is rotated and unfolded with the second connecting plate 252 as the center, and the plug-in column 254 is plugged into the corresponding slot at the end of the main tube 220. At this time, the sleeve 241 is rotated and the hook 243 is pulled to make the movable column 242 extend outward. At the same time, the movable plate 244 squeezes the spring 245, and then the elasticity of the spring 245 is used to clamp the hook 243 on the limiting column 253 to complete the unfolding and fixing of the extension tube 250. The flight of the UAV body 100 is controlled by an external remote control device, and the medicine pump 211 is turned on to transport the medicine liquid inside the spray box 110 to the inside of the main pipe 220 through the liquid inlet pipe 213, the liquid outlet pipe 212 and the connecting pipe 214, and then enters the inside of the extension pipe 250 through the hose 251 and is sprayed out through the nozzle 260. In this way, it can be unfolded during spraying, which is beneficial to increase the spraying area and improve the spraying efficiency. At the same time, it is easy to shield and is beneficial to reduce the temporary space during storage, making it more convenient to use.

[0031] It should be noted that the specific model specifications of the drone body 100 and the drug pump 211 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and principle of the drone body 100 and the drug pump 211 are clear to those skilled in the art and will not be described in detail here.
