摘要
静电喷雾的雾滴穿透力强，命中率高，小雾滴飘失少，覆盖均匀，极大的改善了喷雾效果，减少了农药对环境的污染，提高了对森林病虫害的防治，提高食品的安全性，具有重大意义。静电喷雾装置的研究已经受到科研领域的重视，得到了一定的发展。本课题通过了解防治病虫害的方法和所使用的设备，针对作业条件及其防治病虫害的特点，设计适合风送静电喷雾机。实现农药的低喷量、精喷洒、少污染、高工效、高防效的喷雾，提高作物的安全，满足越来越高的环保和安全要求，也提高了我国植保机械的现代化、智能化水平。用于病虫害防治的风送静电喷雾机主要是利用气流把农药雾滴强制喷入作物株冠层中，这种技术可以增加喷雾的穿透性，并且可以减少雾滴飘移，增加附着率，实现低量喷雾。静电装置可以使雾滴荷电，改善雾滴在作物上的沉积效果，是可行的。

Abstract
Electrostatic spray droplets penetrate strong, hit rate, small droplets drip less, covering evenly, greatly improving the spray effect, reducing the pollution of pesticides on the environment, improve the prevention and treatment of forest pests and diseases, improve food The safety is of great significance. Electrostatic spray device research has been the field of scientific research, has been a certain development. This topic by understanding the methods and equipment used to control pests and diseases, according to the operating conditions and the characteristics of pest control, designed for the wind to send electrostatic spray machine. Achieve low spray volume of pesticides, fine spraying, less pollution, high efficiency, high anti-efficiency spray, improve crop safety, meet the increasing environmental and safety requirements, but also improve the modernization of plant protection machinery in China, the level of intelligence . For the prevention and treatment of pests and diseases of the wind to send electrostatic spray machine is mainly the use of air droplets pesticide droplets forced spray into the plant canopy layer, this technique can increase the penetration of the spray, and can reduce the drift drip to increase the attachment rate, to achieve Low volume spray. Electrostatic devices can make the droplet charge, improve the deposition of droplets on the crop effect is feasible.
