The invention relates to an agricultural plant protection spraying machine, in particular to a gas-assisted type rotational flow atomization static electricity spray gun. The spray gun comprises a rotational flow atomization static electricity nozzle, a telescopic gun barrel, a gun support shell, a high-voltage static electricity generation circuit, a charging battery, a static electricity switch, a gas circuit switch, a liquid circuit switch, a liquid inlet pipe and a gas inlet pipe. When the gas-assisted type rotational flow atomization static electricity spray gun works, high-voltage gas enters a nozzle conical mist chamber firstly from the gas inlet pipe, and it is ensured that a pipeline of the nozzle is smooth, and electric leakage caused by retention of low-pressure liquid flow on the nozzle is avoided; meanwhile, high-voltage static electricity is generated by the high-voltage static electricity generation circuit, and the high-voltage static electricity generation circuit communicates with a conical static electricity device through a high-voltage static electricity circuit and a spring probe; the liquid circuit switch is turned on immediately, and liquid enters the nozzle conical mist chamber to be mixed with the high-speed gas after becoming rotational flow through a rotational flow table from the liquid inlet pipe; and the atomized high-speed gas-liquid two-phase liquid induces electric charges through the conical static electricity device at the front end of the nozzle and then is secondarily atomized and carries electricity, and the liquid and the electricity are blown and sent to the surface of a crop with opposite electric charges.
Description
technical field [0001] The invention relates to an agricultural plant protection spraying machine, in particular to a gas-assisted cyclone atomizing electrostatic spray gun. Background technique [0002] The application of advanced spraying equipment and technology is the key to solving the problem of pests and diseases in our country. The use of advanced spraying technology and the development of efficient spraying equipment are common pursuits in the field of plant protection. Among them, air-assisted spraying technology can enhance the penetration of droplets The penetration ability, while the electrostatic spraying technology can improve the adhesion ability of the droplets. If the two advanced spraying technologies are combined, the effect of complementary advantages can be achieved. At present, air-assisted spraying technology has been gradually applied, but the existing air-assisted electrostatic spray guns have disadvantages such as unsatisfactory charging effect, no...
