Problems solved by technology

For dense seedlings, densely planted fruit trees, and high-stalk crops such as corn and sugarcane, conventional drone spraying technology has insufficient droplet penetration and only floats on the surface of the crops. The control of diseases and insect pests is not in place, resulting in serious agricultural losses.
In addition, conventional UAV smoke is mainly manually ignited on the ground. If it is turned off during aerial work, it needs to be re-ignited after landing, which is more cumbersome to use.

Embodiment 1

[0053] When working, measure the ambient wind speed with an anemometer to ensure that the wind speed is below 1m / s. The remote controller starts the UAV 17 rotors to fly the UAV 17 off the ground. The remote controller starts the air pump 10 by jogging. When the air pump 10 is working, air is injected into the air inlet of the carburetor 3 through the three-way pipe 6; after a few seconds, the remote controller starts the solenoid valve 4 and keeps it normally open. The other end of the through pipe 6 is driven into the pressurized hole on the top of the fuel tank 5, and the oil is pressed out from the oil outlet of the fuel tank 5, and enters the oil inlet of the carburetor 3 through the solenoid valve 4, and is mixed with gasoline to atomize the gasoline , forming an oil-gas mixture; the remote controller starts the high-voltage generator 7 and keeps it normally open, and the spark plug 2 completes the ignition to ignite the oil-gas mixture, which burns in the combustion cha...

Abstract

The invention discloses a pulsating combustion smoke jet device carried by an unmanned aerial vehicle, and belongs to the technical field of plant protection agroforestry equipment. The pulsating combustion smoke jet device carried by the unmanned aerial vehicle mainly comprises a pulsating combustion spray pipe, a carburetor, a sparking plug, a solenoid valve, a fuel tank, a pesticide box, a highpressure generator, an air pump, a liquid pump, a control box and a 12 VDC power supply. The pulsating combustion smoke jet device carried by the unmanned aerial vehicle has the advantages that a smoke pesticide carrying technology and downwash airflow action of a rotor of the unmanned aerial vehicle are used so that smoke particles can penetrate and suspend better in the microclimate environmentinside crops, thereby effectively improving the pesticide applying efficiency and improving the control effect; in addition, the automatic control of oil supply, gas supply and ignition of a pesticide applying device after the unmanned aerial vehicle lifts off is achieved, the problem that ignition cannot be carried out in the air during conventional aviation smoke control is solved, and the device is used more flexibly and more conveniently.

Description

technical field [0001] The invention relates to the technical field of plant protection machinery, in particular to a pulsating combustion smoke injection system carried by an unmanned aerial vehicle. Background technique [0002] UAV plant protection technology integrates aviation technology with traditional plant protection technology, which can provide fast, efficient, penetrating and targeted control coverage. For dense seedlings, densely planted fruit trees, and high-stalk crops such as corn and sugarcane, conventional drone spraying technology has insufficient droplet penetration and only floats on the surface of the crops. The control of diseases and insect pests is not in place, resulting in serious agricultural losses. In addition, conventional UAV smoke is mainly manually ignited on the ground. If it is turned off during aerial work, it needs to be re-ignited after landing, which is more cumbersome to use. Contents of the invention [0003] The purpose of the pr...
