Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and more specifically, to a multi-axis agricultural unmanned aerial vehicle. Background Technique

[0002] An unmanned aerial vehicle, also known as an unmanned aircraft, and an agricultural unmanned aerial vehicle is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aerial vehicle consists of a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. Through ground remote control or navigation flight control, spraying operations can be achieved, and agents, seeds, powders, etc. can be sprayed.

[0003] When an agricultural unmanned aerial vehicle is in use, a box for spraying, fertilizing, sowing and other operations needs to be hung at its bottom. Since the boxes used for spraying, fertilizing, sowing and other operations are different, the existing agricultural unmanned aerial vehicles cannot be universal when being hung, resulting in more trouble. At the same time, when the existing unmanned aerial vehicles are hung, the bearing tension cannot be detected, which easily causes damage to the unmanned aerial vehicle.
