AI Technical Summary

Technical Problem

When using existing rotary tillers to spray pesticides, the pesticide penetration rate is low after the soil is covered, resulting in a reduced contact rate between the soil and the pesticide.

Method used

It adopts an internal spray design, utilizing the combination of curved plates and retaining plates. The contact rate between the soil and the pesticide is improved through the shaking and resetting structure of the curved plates. Combined with the setting of diversion pipes and nozzles, it achieves efficient spraying of pesticides.

Benefits of technology

It increases the contact rate between the soil and the pesticide, enhances the penetration effect of the pesticide, and ensures that the pesticide can quickly and evenly cover the soil.
