Description

Technical Field

[0001] The present invention relates to the field of folding frame structures of unmanned aerial vehicles, and particularly to a folding frame for an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle, also known as an unmanned aircraft, is a type of unmanned robot that can be remotely controlled or fly autonomously. Due to its unique flight capabilities and flexibility, unmanned aerial vehicles have been widely used in multiple fields such as agriculture, land surveying and mapping, power line inspection, environmental monitoring, logistics distribution, film production, and emergency rescue.

[0003] Existing agricultural unmanned aerial vehicles are expensive, and the bodies of agricultural unmanned aerial vehicles are huge and cannot freely shuttle through fruit forests to spray pesticides on the tree tops. Ordinary unmanned aerial vehicles, although able to freely shuttle through fruit forests, cannot carry and spray pesticides, and existing agricultural unmanned aerial vehicles require manual pouring of pesticides, which is not only prone to spilling but also wastes manpower.

[0004] Therefore, a folding frame for an unmanned aerial vehicle is designed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the background art and propose a folding frame for an unmanned aerial vehicle.

The first inclined plate 13 and the second inclined plate 14 are used to increase the clamping range, avoiding the drone 1 taking off and landing multiple times to adjust the clamping range. After the drone 1 lands, the trapezoidal part 8 and the square part 35 are driven by the first telescopic cylinder 5 and the second telescopic cylinder 10 to contract towards the pesticide barrel wall, so as to clamp the drone 1 on the pesticide barrel wall. The pesticide pours into the spraying barrel 30 immersed in the pesticide barrel through the through port 31. The filter screen 32 is used to prevent the fruit tree leaves falling into the pesticide barrel from entering the spraying barrel 30. The scraping ruler 34 is used to clean the fruit tree leaves adsorbed on the filter screen 32. After the spraying barrel 30 is filled with pesticide, the drone 1 flies to the top of the fruit tree to spray the pesticide.
