AI Technical Summary

Technical Problem

Existing pesticide spraying devices for rice cultivation lack a water mist guiding mechanism, which prevents pesticide droplets from penetrating the dense canopy of rice and effectively delivering the pesticide to the middle and lower layers, thus affecting the spraying effect.

Method used

A jetting plate and air pump system are introduced into the spraying device to guide pesticide droplets and blow open the rice leaves with high-speed airflow, so that the pesticide droplets can penetrate the canopy and enter the middle and lower parts. At the same time, a buffer device is set below the spraying mechanism to stabilize the landing.

Benefits of technology

It improves the stability of drug delivery to the middle and lower layers, enhances pesticide spraying effectiveness, and ensures that pesticides can effectively cover the middle and lower areas of rice paddies.
