Abstract

The invention relates to a liquid spraying rod of an agricultural plant protection unmanned aerial vehicle. The liquid spraying rod comprises a plurality of spraying rod assemblies which are mutually connected in a threaded mode; the spraying rod assemblies located at the two ends of the liquid spraying rod are connected with a plug and a connecting rod in a threaded mode correspondingly, and a ball head is arranged at one end of the connecting rod; liquid flow-through holes which communicate with each other are formed in the spraying rod assemblies, the connecting rod and the ball head correspondingly; each spraying rod assembly comprises a rod body and a spraying head assembly, wherein the outer wall of the rod body is provided with a locating ring; each spraying head assembly comprises a rotating ring and a spraying head connected with the rotating ring; a circle of ring teeth is formed in the circumference of each locating ring; and pawls are further arranged on the inner walls of liquid flow channels. The liquid spraying rod can be connected with the spraying rod assemblies of different numbers so that it can be guaranteed that spraying can be carried out smoothly, normal flight of the unmanned aerial vehicle cannot be affected, and trees and plants cannot be damaged.

Description

technical field [0001] The invention relates to plant protection equipment, and belongs to the field of agricultural equipment. More specifically, the invention relates to a liquid spray boom of an agricultural plant protection drone. Background technique [0002] Plant protection UAV, as the name suggests, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform (fixed wing, helicopter, multi-axis aircraft), navigation flight control, and spraying mechanism. Remote control or navigation flight control to realize spraying operations, which can spray chemicals, seeds, powders, etc. [0003] The plant protection UAV has low operating height, less drift, can hover in the air, does not need a special take-off and landing airport, and the downward airflow generated by the rotor helps to increase the penetration of the fog flow on the crops, high control effect, and remote cont...
