Water supply system for drug spraying unmanned aerial vehicle

Abstract

The invention provides a water supply system for a drug spraying unmanned aerial vehicle. The water supply system for the drug spraying unmanned aerial vehicle is characterized in that the water supply system comprises a busbar and a peristaltic pump assembly, wherein the peristaltic pump assembly comprises motors, pump heads and a converter; the forward and reverse rotation of the motors are controlled to drive the different pump heads through a drive shaft in the converter and two one-way bearings mounted on both end heads of the drive shaft, wherein the two one-way bearings drive in opposite directions; the pump heads supply water for four nozzles through the busbar; when the two motors are rotating forward, the two pump heads are driven under the action of the one-way bearings; after the pump heads take water from a main passage through a water supply passage, the water is sent into a water outlet passage through a water passage, thereby realizing double nozzle water spray; when the two motors rotate in reverse, the other two nozzles are controlled to spray water. The water supply system for the drug spraying unmanned aerial vehicle has the advantages of guaranteeing compact structure, stable operation and low cost with a one-way valve to make the motors rotate forward and reverse so as to run the two pump heads separately, allowing the layout of each passage of the busbarto be ingenious and compact, and facilitating easy modular assembly after the the peristaltic pump assembly is mounted.

Description

technical field [0001] The invention relates to a plant protection drone, in particular to a water supply system for a spraying drone. Background technique [0002] With the rapid development of UAV-related technologies at home and abroad, there are many types of UAV systems, and they are widely used and distinctive, resulting in large differences in size, quality, range, flight height and flight speed. Due to the diversity of drones, there will be different classification methods for different considerations. According to the classification of purposes, drones can be divided into military drones and civilian drones, and military drones can be divided into reconnaissance drones. drones, decoy drones, electronic countermeasures drones, communication relay drones, unmanned fighter jets, and target drones. Civilian drones can be divided into inspection / surveillance drones, agricultural drones, and meteorological drones. drones, exploration drones, and surveying and mapping dro...

AI Technical Summary

Problems solved by technology

At present, four peristaltic pumps are used to supply water to the nozzles. This method has the advantage of precise control, but the cost is high, the water supply system is heavy, there are many pipelines, the overall structure is large, and the installation is inconvenient. Among them, the peristaltic pump generally includes motors and The pump head is equipped with a hose and a roller assembly inside the pump head. The hose is arranged around the circularly distributed rollers in the roller assembly. The circularly distributed rollers rotate to squeeze out the water in the hose.
