[0002] Cotton is an important economic crop in my country. For the application of pesticides in cotton fields, China usually uses pure pressure atomizer sprayers to spray pesticides from the top of the cotton canopy downwards. The liquid pesticide cannot pass through the dense canopy of cotton leaves. Therefore, the amount of liquid pesticide deposited in the middle and lower parts of the canopy is very small, and the pest control effect is not good. In addition, pests such as red spiders and cotton bollworms like to be on the back of the leaves, so traditional pesticide application cannot play a good role.

[0003] With the development of technology, a small number of air-conveying spray cylinders have appeared in the market in recent years.
