Abstract

This paper discusses the observation of different precision spraying processes of pulse width modulated variable sprinkler in electrostatic field under different target area densities and discusses the physical characteristics of precision spraying under electrostatic action of different target area density parameters and pulse width modulated variable sprinkler, the influence of various parameters of precision spraying on spray settling rate. Using different environmental protection liquid, the point cloud density detected by the laser Light Detection and Ranging (LiDAR) sensor was used to test different targets and obtain the physical parameter of area density. The area density of the target was differentiated and classified. According to the area density of the target of different categories, multidirectional research was carried out with the conductivity of the liquid itself and the charge rate of the liquid itself under the action of the electrostatic pulse width modulation variable nozzle. The relationship between the three was studied, and a good spray control strategy was obtained. When the area density was 0.668, the conductivity was 10.0 mS/cm, and the spray pressure was 0.45MPa, the charge-mass ratio was the largest and the deposition effect was the best, this paper studies the improvement of the environment and the sustainable development of pesticide use in the future.
