Problems solved by technology

[0003] The spray head installed on the plant protection UAV requires stable working efficiency and uniform spraying work to ensure efficient spraying work. The existing spray head is not significantly different from the ordinary spray head on the market, and its service life is high under high-intensity work requirements. It is relatively low, and the spraying area is uneven when spraying from high to downward. Therefore, it is necessary to invent a spray head for plant protection drones

Abstract

The invention relates to a liquid spraying head of a plant protection unmanned aerial vehicle. The liquid spraying head comprises a liquid spraying shell, wherein a mounting base is arranged on the surface of the front side of the liquid spraying shell, one end of the liquid spraying shell is in threaded connection with a spraying head tail shell, the other end of the liquid spraying shell is communicated with a spraying head connector, and a liquid outlet is formed in one side of the spraying head connector in a threaded manner; and a liquid cap is arranged in the liquid spraying shell, reinforcing blocks are arranged at the top and the bottom of the liquid cap, and the reinforcing blocks are fixedly arranged at the top and the bottom of the inner wall of the liquid spraying shell. According to the liquid spraying head, by arranging the spray head tail shell, the liquid outlet and a liquid conveying pipe, liquid medicine enters the spray head tail shell from the outer side of the spray head tail shell, is filtered through a filter screen and then enters the liquid conveying pipe, then the liquid medicine is led into the liquid cap to be mixed and conveyed with gas, the mixed gas and liquid are sprayed out from the liquid outlet, liquid is sprayed out through liquid passing openings in the surfaces of movable fan blades and gaps between the movable fan blades, and meanwhile, the movable fan blades can rotate on the inner wall of the liquid outlet, so that the liquid medicine is evenly sprayed to increase the spraying area.

Description

technical field [0001] The invention relates to the technical field of plant protection drones, in particular to a liquid spray head of plant protection drones. Background technique [0002] The plant protection drone is small in size but powerful in function. It can carry 8-10 kilograms of pesticides, spray pesticides at low altitude, and can complete the operation of one mu of land per minute. Its spraying efficiency is 30 times that of traditional manual labor. The aircraft adopts intelligent control, and the operator controls it through the ground remote control and GPS positioning. The downward airflow generated by the rotor helps to increase the penetration of the fog flow on the crops, and the control effect is good. At the same time, the pesticide application is controlled remotely. Greatly improved the safety of pesticide spraying. It can also carry out real-time monitoring of agricultural diseases and insect pests by carrying video devices. [0003] The spray he...
