Design and Experiment of Self-propelled Orchard Sprayer
摘要
Abstract
A self-propelled orchard spray was designed to solve the problems of high labor intensity,poor penetration of fog droplets and serious pesticide pollution in orchard spray in Xinjiang,combined with the requirements of orchard agri-cultural machinery,agronomy and pest control.The whole machine is mainly composed of crawler walking system,spray system and remote control system.The main structural parameters of each part are determined by calculation and analy-sis,and the rationality of the frame structure is analyzed by finite element simulation.In order to verify the operating per-formance of the spray,field tests were carried out on the whole machine spray bar spray device and air-driven spray de-vice with the nozzle flow as the test factor and the spray adhesion rate and spray penetration as the test indicators.The test results show that under the same working conditions,the average spray adhesion rate of the spray bar spray device is higher than that of the air driven spray device.The average spray adhesion rates of the two spray devices are 71.99%and 66.35%respectively,which can meet the spray adhesion requirements.In the penetration test,the variation coeffi-cient of the inner and outer canopy liquid deposition of the wind fed spray device is on average 14%smaller than that of the spray rod spray device,and the penetration of the wind fed spray device is significantly stronger than that of the spray rod spray device.The two kinds of spray devices of spray have good operating effects in terms of adhesion and penetra-tion.At the same time,suitable spray methods can be selected according to different growth periods of fruit trees and dif-ferent agronomic needs to achieve better spray effects.关键词
