Liquid feeding device of agricultural unmanned aerial vehicle and using method of liquid feeding device

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a liquid feeding device of an agricultural unmanned aerial vehicle and a using method of the liquid feeding device. The liquid feeding device of the agricultural unmanned aerial vehicle comprise an unmanned aerial vehicle liquid collecting box, a liquid supply box, a liquid return box, a control panel, a liquid inlet pipeline, a liquid supply pipeline, a liquid return pipeline and a liquid delivering pipeline, wherein a liquid inlet end assembly is arranged on a liquid inlet of the unmanned aerial vehicle liquid collecting box and comprises a liquid inlet port pipe seat, a concentric hole seat, a liquid inlet guide column, an embedded connecting seat, a connecting spring and a limiting screw seat. According to the liquid feeding device of the agricultural unmanned aerial vehicle, an automatic pipeline liquid adding mode is adopted, so that the time and labor are saved, the labor intensity of workers is reduced, the working efficiency is improved, the accurate metering of liquid adding can be realized, excessive liquid carrying capacity of the unmanned aerial vehicle liquid collecting box is avoided, navigation flight control of the unmanned aerial vehicle is facilitated, a pipeline connecting structure which implementing connection by nuts is adopted, thus, connection of liquidadding pipelines is facilitated, the structure is compact and stable, the circumstance that pesticide is splashed out of the unmanned aerial vehicle liquid collecting box due to improper operation tocause pollution of the environment and waste of the pesticide is avoided, and the liquid feeding device of the agricultural unmanned aerial vehicle is economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an agricultural unmanned aerial vehicle liquid filling device and its use method. Background technique [0002] Agricultural drones, also known as plant protection drones and unmanned aerial vehicles, as the name implies, are unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of a flying platform (fixed wing, helicopter, multi-axis aircraft), navigation The flight control and spraying mechanism are composed of three parts. The spraying operation can be realized through ground remote control or navigation flight control. It can spray chemicals, seeds, powder, etc. Agricultural drones have the advantages of low operating height, less drift, hovering in the air, and no need for a dedicated take-off and landing airport. Remote control operation, spraying operators avoid the danger of exposure to ...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides an agricultural drone liquid filling device and its use method, which solves the time-consuming and labor-intensive way of traditional agricultural drone liquid filling, improves the labor intensity of workers, and has low work efficiency , the way of adding liquid by visual inspection is easy to cause excessive liquid in the liquid collection tank of the drone, which is not conducive to the navigation and flight control of the drone, and has high requirements for operation. Improper operation will easily cause the liquid to splash out of the liquid collection of the drone Outside the box, it causes environmental pollution and waste of liquid medicine, which increases the cost and is not conducive to environmental protection.
