Plant-protecting unmanned aerial vehicle used for agriculture

Abstract

The invention relates to a plant-protecting unmanned aerial vehicle used for agriculture. The plant-protecting unmanned aerial vehicle comprises an unmanned aerial vehicle body, a liquid storage box is arranged in the unmanned aerial vehicle body, and two liquid spraying rods are symmetrically connected to the unmanned aerial vehicle body; each liquid spraying rod comprises a plurality of sprayingrod assemblies connected in a threaded mode, and the spraying rod assemblies located at the two ends of each liquid spraying rod are correspondingly connected with a plug head and a connecting rod, aball head is arranged at one end of each connecting rod, and communicated liquid circulating holes are formed in the spraying rod assemblies, the connecting rods and the ball heads; the unmanned aerial vehicle body is provided with a spherical cavity body, the ball heads are installed in the spherical cavity body in an interference mode, and a water outlet hose is further arranged in the unmannedaerial vehicle body; the two ends of the water outlet hose correspondingly communicate with the liquid storage box and the liquid circulating hoes of the ball heads, and the water outlet hose is further provided with an electronic controlling valve; and the spraying rod assemblies comprise rod bodies and spraying head assemblies. According to the plant-protecting unmanned aerial vehicle used foragriculture, the liquid spraying rods can be connected with different number of spraying rod assemblies, so that smooth spraying is guaranteed, and normal flight of the unmanned aerial vehicle is notaffected, and damaging to trees and plants does not occur.

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...

AI Technical Summary

Problems solved by technology

[0006] Based on the above technical problems, the present invention provides an agricultural plant protection drone, which solves the technical problems in the prior art that the spray boom of the plant protection drone cannot be rotated, the length can not be adjusted, and the spraying angle and range cannot be adjusted.
