Unmanned aerial vehicle with spraying function for agricultural and forestry production

Abstract

The invention relates to an unmanned aerial vehicle with a spraying function for agricultural and forestry production. The unmanned aerial vehicle comprises a body, a water tank, a transverse pipe, two flight mechanisms and a plurality of spraying mechanisms. The two flight mechanisms are arranged at the two sides of the body respectively, the transverse pipe is arranged below the body, the transverse pipe is communicated with the water tank through a guide pipe, the spraying mechanisms are evenly distributed below the transverse pipe, each spraying mechanism comprises a nozzle, a vertical pipe and a supporting assembly, a fixing rod, a spring, a sealing block and a sealing plate are arranged inside the vertical pipe, limiting assemblies are arranged at the two sides of the sealing block,and a supporting assembly comprises a supporting plate, a rack, a gear, a first motor and a connecting rod. According to the unmanned aerial vehicle with the spraying function for agricultural and forestry production, the flow rate of liquid inside the vertical pipe is controlled through the spraying mechanisms, and therefore the effect that the unmanned aerial vehicle performs uniform spraying ofpesticide is achieved. Compared with an existing spraying mechanism, the spraying mechanism is simple in structure and convenient to use; practicability is improved, and therefore the market competitiveness of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a spraying function for agricultural and forestry production. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. The machine is equipped with autopilot, program control device and other equipment. Ground personnel use radar and other equipment to track, locate, remote control, telemetry and digital transmission. It can take off like an ordinary airplane under radio remote control, and it can automatically land in the same way as an ordinary airplane landing process when recovering, or it can be recovered with a parachute or a block by remote control. [0003] In the existing drones used for agricultural and forestry production, as the liquid in the water tank is lost, the liquid level will gradually drop, and the pre...

AI Technical Summary

Problems solved by technology

[0003] In the existing drones used for agricultural and forestry production, as the liquid in the water tank is lost, the liquid level will gradually drop, and the pressure of the liquid on the bottom of the water tank will decrease, causing the flow rate of the liquid to gradually slow down, so there will be uneven spraying of pesticides , affecting the growth of crops, thereby reducing the usefulness of existing drones for agricultural production
