Folding mechanism, sprinkler and drone for drones

Abstract

Disclosed is a folding mechanism for UAV, wherein a drive unit is fixed to a shell, a rotating unit pivots relative to the shell and is made to be driven by the drive unit and pivot between a first position and a second position relative to the shell, the rotating unit is capable of staying in the first position or staying in the second position. The folding mechanism avoids sprayer head damages of colliding to other obstacles at the landing site which occurs easily when UAV is landing, and avoids the influence that the sprayer headfixing pole is easily broken, in addition, the sprayer head can be lengthened to prevent the droplets phenomenon of the UAV support. Further, the sprayer head fixing pole can be packed up, that is convenient for UAV packing and transporting, ensuring the life of the sprayer head. The invention discloses a sprayer and an UAV also.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, more specifically, to a folding mechanism for an unmanned aerial vehicle, a sprinkler for an unmanned aerial vehicle, and an unmanned aerial vehicle. Background technique [0002] Existing drones used in agriculture generally have a sprinkler head for spraying pesticides. The sprinkler head is fixed on the sprinkler head fixing rod below the machine arm of the agricultural drone, and the sprinkler head is downwards for spraying medicine. [0003] But the above-mentioned sprinkler head fixing rod cannot be folded up. For the setting method of the sprinkler head of the above drone, the sprinkler head fixing rod is distributed around the fuselage. When landing, the sprinkler head is easy to touch other obstacles at the landing site, causing damage to the sprinkler head. Affected by breaking etc. [0004] In addition, the downward extension of the nozzle of the current sprinkler head may hin...

[0003] However, the above-mentioned sprinkler head fixing rod cannot be folded up

For the setting method of the sprinkler head of the above drone, the sprinkler head fixing rod is distributed around the fuselage. When landing, the sprinkler head is easy to touch other obstacles at the landing site, causing damage to the sprinkler head. affected by breaking

[0004] In addition, the downward extension of the nozzle of the current sprinkler head may hinder the packaging and transportation process, and the length of the nozzle is too short, which may cause the pesticide to spray on the drone's bracket and cause fog droplets, while the length of the nozzle is too long, and it may touch the ground when not in use , causing damage to the sprinkler head
