Description

Technical Field

[0001] The utility model relates to the technical field of plant protection unmanned aerial vehicles, in particular to a high-efficiency drug adding device for a plant protection unmanned aerial vehicle. Background Art

[0002] Plant protection drones, also known as unmanned aerial vehicles, are unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of a flight platform, a navigation flight control, and a spraying mechanism. The spraying operation is achieved through ground remote control or navigation flight control. It can spray pesticides, seeds, powders, etc. The dosing device is used to replenish the drugs inside the plant protection drone to facilitate the subsequent spraying of drugs. For example, a Chinese patent discloses a dosing device for a plant protection drone (authorization announcement number CN217547079U). The patented technology can lift the drugs deposited at the bottom by setting a second rotating rod, a slider and a brush to cooperate with each other, thereby making the drugs and water more evenly mixed, avoiding the situation where the drugs and water are unevenly mixed and the drug concentration is too high in some places to burn plants to death;
