Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, in particular to a plant protection spraying unmanned aerial vehicle. Background Art

[0002] Plant protection spraying drone is a kind of drone equipment specially used for farmland plant protection. It is mainly used for spraying pesticides, insecticides, herbicides and other plant protection agents. With the decreasing number of agricultural practitioners, all aspects of agricultural production are increasingly relying on science and technology and modern agricultural equipment. The use of agricultural spraying drones can improve the efficiency and accuracy of farmland plant protection operations and provide convenience and protection for agricultural production.

[0003] For example, Chinese patent: Publication No. CN208542417U, a spraying UAV, includes a UAV body and a spraying device, the spraying device includes a nozzle and a spray gun body, the nozzle is provided with a first spray outlet, a second spray outlet and a third spray outlet, the first spray outlet is located at the center of the nozzle, the first spray outlet is used to spray liquid medicine, the second spray outlet and the third spray outlet are symmetrically arranged on both sides of the first spray outlet, the second spray outlet and the third spray outlet are used to spray compressed air, the central axes of the first spray outlet, the second spray outlet and the third spray outlet converge at one point, and the nozzle and the spray gun body are detachably connected.

[0004] Although the utility model can control the size of the fan by controlling valves 2 and 3 to increase or decrease the flow of compressed air, a large fan means a large spraying range and can spray crops in a large area, and a small fan means a small spraying range and can spray crops in a small area. The size of the fan is adjusted according to the size of the area of ​​the crop to be sprayed, but when the spraying operation is completed, the inside of the medicine storage box will have residual liquid medicine from the previous operation, but the medicine storage box and the machine body are mostly fixedly connected, which is not convenient to separate, and thus it is not convenient to clean the inside of the medicine storage box. If too much liquid medicine remains inside the medicine storage box, it will have a certain impact on the next pesticide spraying.
