Technical Field

[0001] The utility model relates to the technical field of plant protection UAVs, in particular to a foldable spraying device for agricultural plant protection UAVs. Background Art

[0002] In recent years, with the development of unmanned aerial vehicles, they have attracted much attention due to their advantages such as mobility, quick response, unmanned flight and low operating requirements, and have been applied in many fields such as agriculture and exploration. With the development and innovation of technology, drones are widely used in terrain surveys, agricultural fertilization and spraying and other civilian life fields due to their easy control and compact structure.

[0003] For example, the authorization announcement number "CN216994855U" is named a folding spraying device for plant protection drones. Although it can be quickly clamped on various types of drones through a frame, the controller is equipped with a diaphragm pump to achieve efficient control of the spraying operation, and the rich adjustable components ensure the customized needs of the operator. New folding components and spraying components can be installed as needed. However, when it is necessary to spray pesticides for plant protection, the existing folding spraying device for plant protection drones needs to be manually adjusted by the operator on the ground to unfold the folding spraying devices on both sides of the plant protection drone. After being fixed, the drone will be taken into space for spraying operations. However, such operation is very time-consuming and consumes too much labor of the staff each time. In actual use, it affects the working efficiency of the folding spraying device for plant protection drones.
