Abstract

The invention discloses a net type aerial fog rectifying device of a plant protection unmanned aerial vehicle and an operation method thereof. The net type aerial fog rectifying device comprises a bracket, an electric control system and an aerial fog rectifying mechanism. Spraying equipment is mounted on an unmanned aerial vehicle; the bracket is connected with a foot stool of the unmanned aerialvehicle; the electric control system comprises a power supply, an electric control box, a control unit, a plurality of gyroscopes and an actuator; the electric control box is arranged on a top surfaceof the bracket, the power supply and the control unit are arranged in the electric control box, the actuator is arranged on the bottom surface of the bracket, the control unit is electrically connected with the actuator, the gyroscopes are symmetrically arranged on the bracket by taking a symmetric center of a rotor wing of the unmanned aerial vehicle as a center, and the gyroscopes are electrically connected with the control unit; and the aerial fog rectifying mechanism comprises a sleeve, a telescopic main rib, a plurality of telescopic supporting rods, a plurality of sensors and a rectifying net cover, the actuator is used for controlling overturning of the sleeve, stretching and retracting of the telescopic main rib and stretching and retracting, lifting and rotating of the telescopicsupporting rods, and the power source supplies power to the control unit, the actuator, the telescopic main rib, the telescopic supporting rods and the rectifying net cover.

Description

technical field [0001] The invention relates to the technical field of agricultural aviation plant protection spraying, in particular to a net-type aerosol rectification device for a plant protection drone and an operation method thereof. Background technique [0002] The rural areas of our country are increasingly laborious, and agricultural mechanization has become the only way for my country's agricultural development. Agricultural mechanization has given birth to various agricultural machinery and equipment. Among them, plant protection drones are widely favored and adopted by the market due to their high efficiency, flexibility and safety. . [0003] The application of plant protection drones in agriculture (Chunduri and Menaka 2019) has a wide range of scenarios. Low-altitude and low-volume pesticide application technology is one of the hot applications. In order to achieve the expected control effect while avoiding the waste of liquid medicine, improve the spray drople...
