Aerosol sprayer for plant protection unmanned aerial vehicle

Abstract

The invention discloses an aerosol sprayer for a plant protection unmanned aerial vehicle, and relates to the technical field of aerosol sprayers. The aerosol sprayer comprises an aerosol sprayer body, a combustion chamber, a combustion mechanism, an oil pump, an assistant pump, a pesticide pump, an oil tank, an assistant tank, a pesticide tank and a remote controller, wherein one end of the aerosol sprayer body is fixedly connected with one end of the combustion mechanism, the other end of the combustion mechanism is fixedly connected with one end of the combustion chamber, a centrifugal fan is arranged at the end, away from the combustion mechanism, of the aerosol sprayer body, a fixing block is arranged at the end, close to the filter screen, of the aerosol sprayer body, a buckle is arranged at one end of the fixing block, and a damping connecting piece is arranged between the fixing block and the buckle. The combustion mechanism has the advantages of being small in size and light in weight, the cruising ability of the unmanned aerial vehicle can be improved, the pesticide applying efficiency is improved, an ignition rod is good in stability and not prone to damage, and the maintenance cost is reduced; and the fixed installation of the aerosol sprayer and the unmanned aerial vehicle has a damping structure design, vibration of the unmanned aerial vehicle is reduced, and the risk of aerosol sprayer crash caused by joint breakage is avoided.

Description

technical field [0001] The invention relates to the technical field of fog machines, in particular to a fog machine used on plant protection drones. Background technique [0002] Fog machine, also known as smoke sprayer, is a spray machine designed and manufactured using the working principle of pulse jet engine for insecticide, disinfection or fertilization. It has good penetrability and diffuseness, and has been popularized and applied in modern agriculture; The combination of fog machines and UAVs has the advantages of high efficiency and easy operation compared with manual spraying, and has been widely used in recent years. Generally, the fog machines are installed on UAVs for cotton, wheat, rice, and corn. Pest control and high-efficiency fertilizer spraying of crops, greenhouse crops, fruit trees, forests, tea gardens and other plants. At present, due to its own structure, the fog machine has a large volume and weight, and the high-pressure ignition module is easily d...

AI Technical Summary

Problems solved by technology

At present, due to its own structure, the fog machine has a large volume and weight, and the high-pressure ignition module is easily damaged, which affects the load and endurance of the drone, and ultimately leads to a decrease in the spraying efficiency; the common problem of the pulse fog machine is poor stability. Turn off the flame, and the industry still has not found a good solution; the existing smoke machine and the drone are installed rigidly, and the drone has been vibrating at high frequency during use, which will cause the drone and the smoke machine to sway for a long time. A break in the connection puts the fog machine at risk of crashing
