Plant-protection unmanned aerial vehicle capable of achieving precise spraying and used for agricultural production

Abstract

The invention relates to a plant-protection unmanned aerial vehicle capable of achieving precise spraying and used for agricultural production. The plant-protection unmanned aerial vehicle comprises amain body, a pesticide tank, a liquid injection pipe, a liquid delivery pipe, a spraying pipe, a windproof mechanism, a plurality of spray heads and a plurality of propellers, the windproof mechanismcomprises an adjustment assembly, a rotating disc and two windproof assemblies, the adjustment assembly comprises a first motor, a first gear and a second gear, the windproof assembly comprises a windproof film, an adjusting unit and two windproof units, and each windproof unit comprises a driving rod, a rotating rod and a supporting foot. According to the plant-protection unmanned aerial vehiclecapable of achieving precise spraying and used for agricultural production, after the wind power direction is detected through a wind direction sensor, the position of the windproof assembly in the windproof mechanism is controlled through the adjustment assembly, the supporting feet are expanded, the windproof film blocks wind power, the situation that pesticide drops sprayed by the spray headsare blown by wind and consequently offset is avoided, thus pesticides are precisely sprayed onto crops, growing of the crops is promoted, and the practicability of the plant-protection unmanned aerialvehicle is improved.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to a plant protection drone with precise spraying 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] Although the plant protection UAV facilitates the spraying work and improves the spraying efficiency, during the spraying process, the sprayed medicine droplets are easily affected by the external wind and shifted, causing the medicine droplets sprayed by the plant protection UAV to leave the target position, causing the It is difficult for the agricultural and forestry plants under the drone to receive the drops. Due to inaccu...

[0003] Although the plant protection UAV facilitates the spraying work and improves the spraying efficiency, during the spraying process, the sprayed medicine droplets are easily affected by the external wind and shifted, causing the medicine droplets sprayed by the plant protection UAV to leave the target position, causing the It is difficult for the agricultural and forestry plants under the drone to receive the drops. Due to inaccurate spraying, the growth of agricultural and forestry crops is affected, which reduces the practicability of the existing plant protection drones.
