[0026] The present invention will now be described in further detail in conjunction with the full text.

[0027] Combined with appendix Figures 1-3 A pesticide dispensing mechanism for an agricultural drone includes a main body 1 and a spreading device. The spreading device is installed at the lower end of the main body 1 and includes a pesticide storage tank 2 at the lower end of the main body 1. A rotary spraying device 3 is rotatably connected to the lower center of the pesticide storage tank 2, and auxiliary spraying devices 4 are rotatably connected to the four corners of the lower end of the pesticide storage tank 2. The auxiliary spraying devices 4 and the rotary spraying devices 3 are arranged alternately. The auxiliary spraying devices 4 and the rotary spraying devices 3 spray pesticides in a rotating manner, resulting in a wider spraying range. The pesticide extends outward due to centrifugal force, which is very convenient. The pesticide is sprayed on the farmland while the main body 1 of the agricultural drone is moving. Using agricultural drones for pesticide spraying can greatly improve the spraying speed and efficiency. The maximum flight speed of agricultural drones can reach over 50 kilometers per hour, and they can also perform rapid detection of large areas of farmland. Using agricultural drones for agricultural plant protection can greatly reduce the risk of workers coming into contact with pesticides and reduce environmental pollution.

[0028] In specific implementation of this utility model, such as Figures 1-3As shown, a rotary spraying device 3 is rotatably connected to the lower middle part of the medicine storage tank 2. The rotary spraying device includes a first movable tube 303 connected to the medicine storage tank 2 by a bearing. A rotating tube 301 is connected to the outside of the movable tube 303. The rotating tube 301 has a spiral structure. Multiple sets of first nozzles 302 are installed at the lower end of the rotating tube 301. An auxiliary spraying device 4 is rotatably connected to the four corners of the lower end of the medicine storage tank 2. The auxiliary spraying device 4 includes a second movable tube 403 connected to the medicine storage tank 2 by a bearing. An auxiliary tube 401 is connected to the outside of the second movable tube 403. The auxiliary tube 401 has a spiral downward structure. Multiple sets of second nozzles 402 are provided on the outside of the auxiliary tube 401. The rotating pipe 301 has a spiral structure, and the auxiliary pipe 401 has a downward spiral structure. Driven by water pressure, the water flows into the auxiliary pipe 401 and the rotating pipe 301, causing the auxiliary pipe 401 to rotate on the storage tank 2 via the second movable pipe 403. The rotating pipe 301 also rotates on the storage tank 2 via the first movable pipe 303. The rotating spraying device 3 rotates, spraying directly below the main body 1 of the agricultural drone through the first nozzle 302. The auxiliary spraying device 4, consisting of multiple sets, sprays around the main body 1 of the agricultural drone through the second nozzle 402, thus treating the farmland with pesticides. Using an agricultural drone for pesticide spraying can greatly improve spraying speed and efficiency.

[0029] In specific implementation of this invention, the height of multiple first nozzles 302 is consistent, enabling different levels of drug spraying and avoiding uneven spraying.

[0030] In specific implementation, this utility model Figure 2 and Figure 3 As shown, a partition 5 is installed inside the medicine storage tank 2, dividing the tank into an equipment area 6 and a medicine storage area 7. A water pump 9 and a connecting block 8 are fixedly installed in the equipment area 6. A first connecting pipe 10, inserted into a second movable pipe 403, is installed on the outside of the connecting block 8. A second connecting pipe 11, inserted into a first movable pipe 303, is installed at the lower end of the connecting block 8. A water inlet area 12, connecting the first connecting pipe 10 and the second connecting pipe 11, is opened inside the connecting block 8. The inlet of the water pump 9 is connected to the medicine storage area 7, and its outlet is connected to the water inlet area 12. The water pump 9 transports the medicine from the medicine storage area 7 to the water inlet area 12, increasing the water pressure. The medicine in the water inlet area 12 is transported from the second connecting pipe 11 and the first connecting pipe 10 to the first movable pipe 303 and the second movable pipe 403, and then to the auxiliary pipe 401 and the rotating pipe 301. Due to the spiral structure of the auxiliary pipe 401 and the rotating pipe 301, centrifugal force is generated, completing the rotational spraying. Example

[0031] The diameter of the first connecting pipe 10 of this invention is smaller than the diameter of the second connecting pipe 11. Most of the medicine enters the rotary spraying device 3 through the second connecting pipe 11 for spraying. Specifically, the rotating pipe 301 is connected to the first movable pipe 303, and the auxiliary pipe 401 is connected to the second movable pipe 403. The diameters of the second movable pipe 403 and the first movable pipe 303 are both larger than those of the auxiliary pipe 401 and the rotating pipe 301, so that medicine can enter from a large aperture into a small aperture, which can accelerate the flow of medicine and achieve acceleration and propulsion effects. Example

[0032] Using existing technology, the plant protection drone 1 drives the device to fly. The water pump 9 transports the pesticide from the storage area 7 to the water inlet area 12 and increases the water pressure. The pesticide in the water inlet area 12 is transported from the second connecting pipe 11 and the first connecting pipe 10 to the first movable pipe 303 and the second movable pipe 403, and then to the auxiliary pipe 401 and the rotating pipe 301. Due to the spiral structure of the auxiliary pipe 401 and the rotating pipe 301, centrifugal force is generated to spray pesticides, which can greatly improve the spraying speed and efficiency.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
