Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) pesticide spraying, in particular to a UAV pesticide spraying suspension device. Background Art

[0002] When a drone is spraying pesticides, a corresponding suspension device is usually used to store, prepare, and spray the pesticides. Reference publication number CN219679593U discloses a drone pesticide spraying suspension device, which includes a plant protection drone and a storage mechanism. The storage mechanism includes a medicine cartridge, a simple cover, and a feed hopper. A sealing mechanism is provided in the feed hopper, which eliminates the need for pre-stirring, improves work efficiency, and can limit the fluctuation of the medicine liquid in the medicine cartridge. As described in the above patent, when using existing drone pesticide spraying suspension devices, some adopt a method of setting complex stirring device components at the pesticide storage end to achieve stirring of the stored pesticide. This arrangement requires slow loading of the pesticide at the liquid storage end after spraying the pesticide, thereby affecting the efficiency of the device. Most suspension devices that directly replace the pesticide storage cartridge have difficulty in stirring the pesticide cartridge, affecting the spraying quality of the pesticide. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a drone pesticide spraying suspension device, which solves the problem that most of the stirring ends of the device are difficult to provide power for the pesticide inside the agitator of the liquid storage end without affecting the rapid replacement of the liquid storage end.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A drone pesticide spraying suspension device includes a frame, the upper side of which is connected to a suspension member for drone pesticide spraying, the suspension member including:

[0005] A liquid storage member is installed on the upper side of the frame for storing and stirring pesticides.
