Pesticide spraying unmanned aerial vehicle for reducing drifting of liquid pesticides

Abstract

The invention discloses a pesticide spraying unmanned aerial vehicle for reducing the drifting of liquid pesticides. The pesticide spraying unmanned aerial vehicle structurally comprises a vehicle body, propellers, arc-shaped self-shielding devices, a liquid pesticide tank, a spray nozzle and landing skids, wherein the propellers are fixed on the top surface of four corners of the vehicle body. Bysensing the wind through the arrangement of wind sensors, the pesticide spraying unmanned aerial vehicle rotates driving parts on driving mechanisms to cause force transfer pushing parts to quickly push out and trigger ejection mechanisms, and enables multi-section support rods to drive the ejection of telescopic shielding plates, thereby shielding the liquid pesticide tank, blocking the wind force, normally and accurately spraying the liquid pesticides onto the area, preventing the liquid pesticides from being blown by the wind to surrounding vegetable fields, reducing the risk of poisoning,and improving the effect of spraying the liquid pesticides. The pesticide spraying unmanned aerial vehicle utilizes small fluff on the inner walls of the telescopic shielding plates to form the samehydrophobicity as lotus leaves, thereby enabling the liquid pesticides sprayed on the telescopic shielding plates to roll down to farmland, preventing the liquid pesticides from adhering to the surfaces of the telescopic shielding plates, further improving the utilization rate of the liquid pesticides, and maximally avoiding the waste of the liquid pesticides.

Description

technical field [0001] The invention relates to a medicine spraying unmanned aerial vehicle which reduces the drift of medicinal liquid, and belongs to the technical field of unmanned aerial vehicles. Background technique [0002] With the continuous development of modern drones, more and more drones are applied to various fields. Among them, in order to reduce the intensity of farmers' manual spraying and improve the efficiency of farmland spraying, the spraying drones in agricultural machines are used in various fields. It has become more and more popular in the market, but the existing spraying drones have the following disadvantages: [0003] During the flight operation of the spraying drone, since there is no shield around the spraying area, the sprayed liquid medicine will be blown away and drifted due to the blowing of the external wind force, and cannot be accurately dripped on the area. As a result, some areas cannot be sprayed, and there are spray shadows. If ther...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a spraying drone that reduces the drift of the liquid medicine, so as to solve the problem that the above-mentioned spraying drone has no shielding boards around the spraying place when the above-mentioned spraying drone is flying. The sprayed liquid medicine will be scattered and drifted by the blowing of the external wind, and cannot be accurately dripped on the area, resulting in some areas being unable to be sprayed, and there is a spray shadow. If there is a vegetable field around, it will If the medicinal liquid drifts on it, there will be a hidden danger of pesticide poisoning when eaten, and it will also lead to the waste of medicinal liquid, which will reduce the spraying effect of the entire spraying operation.
