Pesticide spraying unmanned aerial vehicle capable of pushing and pulling extension pipe up and down by natural force

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses a pesticide spraying unmanned aerial vehicle capable of pushing and pulling an extension pipe up and down with the help of natural force. An air filtering hole is formed in a vehicle top shell, when the unmanned aerial vehicle is used, air passes through the air filtering hole, the pressure of the wind power onthe unmanned aerial vehicle is reduced, and unstable factors caused by the wind power in the irrigation process are avoided. When the unmanned aerial vehicle runs, the protective cover touches a plant and pushes the lower pull rod; the lower pull rod and the upper pull rod are fixed through clamping strips; the upper pull rod is pushed upwards, the upper pull rod drives the parallel fixing frameto move upwards, the parallel fixing frame and the outer ring pipe are fixed to drive the outer ring pipe to push upwards, the bottom of the outer ring pipe is fixed to the upper end of the spraying agent pipe shell, the spraying agent pipe shell moves upwards to drive the internal extension pipe to slide up and down, and the plant is prevented from being directly touched by a spraying agent opening.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a spraying drone that pushes and pulls an extension tube up and down by natural force. Background technique [0002] The operator uses the remote control to control the spraying UAV, so that the spraying UAV can freely spray pesticides in the field. The existing spraying UAV will inevitably be affected by the wind during the spraying process. It makes it impossible for the UAV to operate smoothly during the spraying process. [0003] During the operation of the UAV, the operator should not raise the UAV too high to prevent the UAV from harming the surrounding fields, but too low will often cause the spray nozzle to directly touch the field. When touching the tender seedlings of the plant, the development of the tender seedlings of the plant will be affected easily if it is stained with pesticides with too high concentration.

[0003] During the operation of the UAV, the operator should not raise the UAV too high to prevent the UAV from harming the surrounding fields, but too low will often cause the spray nozzle to directly touch the field. Touching the tender seedlings of the plant, the development of the tender seedlings of the plant will be affected easily if it is stained with too high a concentration of pesticides
