Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural machinery. BACKGROUND

[0002] Pesticide spraying operation is a relatively routine activity in agricultural production. In the past, artificial spraying was used, and currently unmanned aerial vehicles and pesticide spraying machines have gradually replaced it. However, the current pesticide spraying equipment can only spray one type of pesticide at the same time, and if multiple types of pesticides need to be sprayed, the pesticides must be mixed together and sprayed. However, some pesticides cannot be directly mixed and used because they may react chemically. Therefore, they can only be sprayed multiple times, which is time-consuming and labor-intensive.

[0003] In addition, there are some special drugs, such as Bordeaux mixture, which is prepared by mixing copper sulfate, quicklime, and water and then sprayed. After mixing, the chemicals react to form copper hydroxide. If it cannot be sprayed at once, copper hydroxide will form precipitates or floccules, causing the nozzle to clog, affecting work efficiency, and increasing operating costs.

[0004] Currently, a horizontal spray bar is used on the pesticide spraying machine, and the nozzles are arranged in a line on the horizontal truss according to the position of the ridge and furrow. This cannot be used for spraying multiple types of pesticides at the same time. SUMMARY
