Development of pest control machine capable of reduction of pesticides dropping on the agricultural field

杀虫剂喷雾控制虫害不能避免偏离原来目标的目的。这项研究是为了减少农药漂移的目的。对悬臂式喷雾器喷嘴喷出的颗粒进行了视觉运动解析。采用数值分析的方法，对矩形箱体内颗粒的运动规律进行了研究。在此基础上，设计并研制了基于除雾器的弯刀式除雾器。在实验室实验中，取得了颗粒收集率高的结果。

Pesticide spray for insect pest control cannot avoid drifting out of purposes other than the original target. This study is done to make pesticide drifting out of purposes reduced. Particles sprayed from the nozzle of boom sprayer were analyzed using visual motion interpretation. Numerical analysis method was carried out in order to get knowledge about the motion of particles in the rectangular box. Furthermore, collecting implement attached with curved blade, which is based on the mist eliminator, was designed and developed. The result of high collection rate of particles was obtained at the laboratory experiment.
