Evaluation of the effect of spray flow rate and the nozzle velocity on the deposition of droplets

The spray distribution of field operation pesticide spraying machine, not only is affected by the shape of the nozzle, nozzle pressure and wind speed around the crop environment, but also has certain indispensable link to spraying equipment and carrying machine motion state. The robot uses the wheel speed sensor to accurately measure the state of motion sprayer, and uses a real-time sensor to monitor the flow of spray. Based on the spray different motion state settlement sample collection, we analyze the deposition of droplet, and draw the conclusion that the influence of the state of motion on spray droplet deposition can be divided into sensitive areas, the linear region and the weak areas. Compared with other studies, the effects of Spray source status on spray deposition is similar to the impact of local air source settling.
