摘要
为了控制和防止蝗灾大面积爆发,开发了高压静电喷洒灭蝗车。考察了双流体雾化喷嘴各控制参数之间的相互关系,发现改变气液压力配比可以有效调节双流体喷嘴的喷量和雾滴粒径。在此基础上,对高压静电喷洒灭蝗车进行雾滴沉积特性试验和草原灭蝗试验,雾滴粒径和沉积分布在射程方向上呈现双峰特性,蝗虫杀灭率可达93%,喂毒性药剂的灭蝗效果比触杀性药剂好。
A high voltage electrostatic spraying vehicle was developed to control locusts in agriculture and stockbreeding. The experiment of two-fluid spray nozzle was carried out and the relationship of control parameters was obtained. It was found out that the liquid flow and droplet diameter could be adjusted by changing the proportion between gas pressure and liquid pressure. Meanwhile, the integrated vehicle experiment was conducted to get vehicle characteristics and locust-killing effects. The experimental results showed that droplet diameter distribution and deposition distribution had two peaks in spraying direction, the locust-killing rate of the vehicle could reach 93%, and locust-killing effect with absorbing pesticide was better than that with touching pesticide.
