Abstract

The invention discloses a combustion device for a smoke sprayer on a plant protection unmanned aerial vehicle, and relates to the technical field of smoke sprayers. The combustion device comprises a fuel tank and a combustion mechanism, the combustion mechanism comprises a combustion nozzle, a spray pipe, a metal pipe and an electronic igniter, the metal pipe surrounds the spray pipe in the axialdirection, and the metal pipe is provided with a bent part located right in front of the end of the spray pipe; and the fuel tank is in an inverted state with a downward opening, a first one-way valveis arranged at one end of a fixing connector, a pressure regulating valve is arranged at one end of the first one-way valve, and a second one-way valve is arranged at one end of the pressure regulating valve. According to the combustion device, electric energy of the unmanned aerial vehicle does not need to be continuously used, and the power and working efficiency of the unmanned aerial vehicleare improved; inverted vaporizing combustion is adopted, and the heating effect on a heating spiral pipe is guaranteed; and the pressure regulating valve can regulate the pressure to ensure that the pressure value of liquid fuel from the fuel tank is stable, and the pesticide spraying effect is improved.

Description

technical field

[0001] The invention relates to the technical field of fog machines, in particular to a combustion device for a fog machine on a plant protection drone. Background technique

[0002] The fog machine, also known as the smoke sprayer, is a machine that makes the mixture of pesticides and water into smoke, and sprays pesticides and fertilizers on crops. Because of its excellent penetrability and diffuseness, it has been widely used in modern agriculture. Good application, the combination of fog machine and UAV has a better application prospect, and has been widely promoted in recent years. Generally, the fog machine is installed on the UAV for cotton, wheat, rice, corn and other crops, Pest control and high-efficiency fertilizer spraying for greenhouse crops, fruit trees, forests, tea gardens and other plants. At present, the fuel in the fuel tank of the smoke machine needs to be heated first to make the fuel change from liquid to gaseous. Since the butane gas ...
