Abstract

A centrifugal atomizing system has been designed for plant protection unmanned aerial vehicles (UAVs) with the centrifugal atomizing principle with the aim to ensure good prevention and treatment effect of the plant protection UAV and reduce power consumption. It consists of a pesticide tank, an electromagnetic valve, a dispenser, a pesticide transport pipe, an atomizer and a mounting track. SolidWorks is used for virtual design and simulation analysis to produce a 3D model and performs finite element analysis on the mounting rack to optimize the structure, verify motion reliability of the atomizer and the atomizing effect. The prototype test results show that the system can complete atomization of the pesticide liquid without pressurization, which not only achieves a good atomization effect, but also saves electricity. This system features a simple structure, low manufacturing cost, safe and reliable use, easy maintenance, and low failure rate and thus boasts of broad promotion value in UAV plant protection.
