Agricultural production-oriented plant protection unmanned aerial vehicle with good spraying effect

Abstract

The invention relates to an agricultural production-oriented plant protection unmanned aerial vehicle with a good spraying effect. The unmanned aerial vehicle comprises a main body, a pesticide box, apesticide injection port, a spraying mechanism and multiple flying mechanisms; each flying mechanism comprises a fixing pipe, a supporting leg, a rotor wing and a telescopic assembly, wherein the telescopic assembly comprises a translation unit, a translation plate, an air pump, an air cylinder, a sealing plate and an air rod; the spraying mechanism comprises a lifting assembly, a vertical pipe,a transverse pipe and a plurality of nozzles. According to the agricultural production-oriented plant protection unmanned aerial vehicle with the good spraying effect of the invention, the rotor wingsthe flight mechanisms move away from the main body, so that the distances between the rotor wings and the nozzles in a horizontal direction are increased; and in the spraying mechanism, through the downward movement of the transverse pipe and the vertical pipe, the distances between the nozzles and the rotor wings in a vertical direction are increased, and therefore, the influence of the rotor wings on crop leaves is further weakened, the distortion degree of the crop leaves is reduced, the attachment rate of pesticide drops and the good spraying effect of equipment are guaranteed, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a plant protection drone with good spraying effect for agricultural production. Background technique [0002] Plant protection UAV, also known as unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. Composed of three parts, the spraying operation can be realized through ground remote control or navigation flight control, which can spray chemicals, seeds, powder, etc. [0003] When the existing drones perform plant protection operations, the wind generated by the rotor will distort and deform the leaves of the crops, and when the drone flies away, the crops will return to their original state and the droplets deposited on the crop leaves will be distorted and deformed. Bounce back, reduce the adhesion rate of the medicine droplets, make it difficult for the plant protection operation to achieve ...

AI Technical Summary

Problems solved by technology

[0003] When the existing drones perform plant protection operations, the wind generated by the rotor will distort and deform the leaves of the crops, and when the drone flies away, the crops will return to their original state and the droplets deposited on the crop leaves will be distorted and deformed. Popping back out reduces the attachment rate of the drug droplets, making it difficult for the plant protection operation to achieve the expected effect, thereby reducing the practicability of the existing plant protection drones
