Plant-protecting unmanned aerial vehicle used for agriculture

Abstract

The invention relates to an agricultural plant protection drone, which includes a drone body, a liquid storage box is arranged inside the drone body, and two liquid spray bars are symmetrically connected to the drone body; the liquid spray bar includes a plurality of threaded connections The spray rod assembly located at both ends of the liquid spray rod is threadedly connected with a plug and a connecting rod, one end of the connecting rod is provided with a ball head, and the inside of the spray rod assembly, the connecting rod and the ball head are all provided with interconnected liquid circulation hole; the drone body is provided with a spherical cavity, and the ball head is installed in the spherical cavity with interference. There is also a water outlet hose inside the drone body, and the two ends of the water outlet hose are connected to the liquid storage tank and the ball head respectively. hole, the water outlet hose is also provided with an electronic control valve; the spray rod assembly includes a rod body and a spray head assembly. The liquid spray rod of the present invention can be connected with different numbers of spray rod components, so as to ensure the smooth progress of spraying without affecting the normal flight of the drone and damaging trees and plants.

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 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 control operation , Sprayin...
