Description

Technical Field

[0001] This utility model belongs to the field of agricultural aviation operation support vehicles, specifically relating to a compact unmanned aerial vehicle (UAV) plant protection vehicle. Background Technology

[0002] Agricultural drones, also known as unmanned aerial vehicles, are unmanned aircraft used for the protection of agricultural and forestry plants. These drones consist of three parts: a flight platform (fixed-wing, helicopter, or multi-rotor aircraft), a navigation and flight control system, and a spraying mechanism. They can spray pesticides, seeds, powders, etc., through ground remote control or navigation and flight control.

[0003] However, agricultural drones face the challenge of not being able to operate at high frequencies. Existing drone-carrying vehicles are large and expensive, and most drone operation vehicles are large box trucks, which are not suitable for ordinary farmers. Furthermore, the existing agricultural vehicles have limited interior space and small water tanks, which cannot provide the necessary power for high-frequency drone operations. Therefore, a small pickup truck is proposed to carry agricultural drones, reducing the size of the drone operation vehicle while ensuring the supply of power for drone operations.
