An air-assisted large-width plant protection unmanned helicopter and its operating method

Abstract

The invention relates to an air-assisted wide plant protection unmanned helicopter and an operation method implemented by the same. The air-assisted wide plant protection unmanned helicopter comprises an air-assisted air duct device, a support frame, a storage battery, an electric diaphragm pump, a chemical tank and a foldable spray rod. The air-assisted air duct device, the support frame, the storage battery, the electric diaphragm pump, the chemical tank and the foldable spray rod are mounted on an unmanned helicopter, spray nozzles are distributed on the foldable spray rod, the foldable spray rod is divided into a middle main spray rod, first spray rods and second spray rods, and the first spray rods and the second spray rods are arranged on the two sides of the foldable spray rod. Downwash airflow formed by the unmanned helicopter is accelerated by the aid of conical pipeline structures, and high-speed airflow flows through vertical flat columnar air pipes and then flows into horizontal flat tapered air pipes; an air curtain is formed on the spray rods in the width direction of the spray rods by the high-speed airflow, the air speed of the air curtain is downwardly uniformly distributed, accelerating, carrying and secondary atomizing effects can be realized for fog-drops by the air curtain, and the fog-drops are atomized by the spray nozzles. The air-assisted wide plant protection unmanned helicopter and the operation method have the advantages that the working widths of the spray rods are increased, so that the chemical application rate can be increased under the condition that the chemical liquid carrying amount of the unmanned helicopter is unchanged, the operation time can be shortened, the chemical application efficiency can be improved, and power consumption of the unmanned helicopter can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural aviation plant protection, in particular to an air-assisted large-scale wide spraying unmanned plant protection machine for agricultural and forestry plant protection and its operation method, so as to improve the spraying efficiency, increase the anti-drift performance and uniform deposition performance of droplets. Background technique [0002] The remote control unmanned helicopter for plant protection is mainly used for the spraying of food or economic crops in large areas of forest or farmland. The high-speed downwash airflow generated by the high-speed rotating rotor can realize the secondary atomization of the sprayed droplets from the nozzle and improve the spraying effect of the fog. The entrainment ability of the droplet can improve the penetration of the liquid medicine, and it has many advantages such as good effect on the control of diseases, insect pests and weeds, and it can be operated r...
