摘要
针对新疆南疆温室作物植保作业机械化程度低、雾滴雾化效果不均匀、叶面覆盖不足等问题,本研究采用遥控和风送静电技术设计了满足温室自走喷药的一款风送静电喷雾机。该喷雾机的设计包括整体结构、风送装置和静电系统,并以雾化粒径和叶面覆盖程度为性能验证指标,对喷雾机的风送静电效果展开了样机试验。结果表明,静电与非静电喷雾作用下雾滴粒径大小具有一定差异,静电喷雾雾滴大小相对均匀,满足杀伤叶面爬行类害虫幼虫的粒径范围;同时静电作用时,植株叶面正、反面平均农药附着率分别提高了10.43%、17.32%,提升了雾滴的附着效果,达到了节药杀虫的目标。
Considering the plant protection operations for greenhouse crop in Southern Xinjiang widely exist some limitations,showing low degree of mechanization,uneven atomization effect of fog droplets,insufficient leaf cover and so on.A wind-fed electrostatic sprayer to meet the greenhouse self-propelled spraying was designed by adopting remote control and wind-fed electrostatic technology.The sprayer consists of overall structure,the air delivery device and the electrostatic system.And then,the air delivery electrostatic effect of the sprayer was testedin which the atomized particle size and the degree of leaf coverage are taken as the performance verification indexes.The results suggested that droplet size has certain differences,between electrostatic and non-electrostatic spraying action,showing electrostatic spray droplet size is relatively uniform,which meet the particle size range used to kill crawling pests and larvae on surface of flying foliage.In addition,due to electrostatic action,the average attachment of the plant foliage on the front and back sides increase in 10.43%and 17.32%,respectively,which enhances the effect of the droplet adhesion,and further achieve the goal of the savings drug to killing the pests.
