【摘要】 提高农药利用率、减少农药使用量是保护环境实现乡村振兴发展措施之一,因而对旋翼植保机雾滴沉积进行研究显得十分必要。为了探究影响旋翼植保机雾滴沉积的因素,利用喷雾性能综合试验台(吉林省农业机械研究院研制)对旋翼植保机在不同作业高度、旋翼转速和离心喷头转盘转数条件下的雾滴沉积进行了测试,并对试验结果进行了分析。结果表明:作业高度对有效沉积率影响显著,旋翼转数和离心喷头转盘转数对沉积量影响不显著,作业高度对雾滴分布均匀性影响显著;NJY-1206植保无人机施药最佳参数为:高度1m、旋翼转速3800r/min、离心喷头转速10 000r/min。更多还原

【Abstract】 Improving the utilization rate and reducing the use amount of pesticides is one of the measures to protect the environment and realize rural revitalization and development.It is very necessary to study the droplet deposition of rotor-craft for plant protection.In order to explore the factors that affect the droplet deposition of plant protection rotorcraft, this study tested the droplet deposition of rotorcraft under different spray heights, rotor speeds and centrifugal nozzle revolutions by using the comprehensive spray bench( developed by Jilin provincial academy of agricultural machinery),and conducted regression analysis on the deposition characteristics of 17 test groups.The results show that the spray height has a significant effect on the effective deposition amount,while the rotor revolution and centrifugal nozzle revolution have no significant effect on the deposition amount.The optimal parameters for NJY-1206 UAV for plant protection are height of 1 m,rotor speed of 3800 r/min and centrifugal nozzle speed of 1000 r/min.更多还原
