AI Technical Summary

Technical Problem

Existing rice seedling rolling machines have problems in the cultivation of machine-transplanted rice seedlings, such as complicated preparation process, time and labor consumption, small plastic tray size, frequent machine stops for loading during machine transplanting, which limits transplanting efficiency, and the preparation of new seedling substrate is complicated and expensive.

Method used

An automatic seedling rolling device was designed, including a vehicle body, a seedling rolling mechanism, clamping plates, a seedling rolling motor, and a control motor. The clamping plates clamp the seedlings and the seedling rolling motor drives the seedling rolling shaft to rotate, thereby realizing the automatic rolling of the seedlings and the culture medium. The efficiency of seedling rolling is improved by combining a pusher plate and a lifting mechanism.

Benefits of technology

It enables rapid transplanting of seedlings, improves the efficiency of seedling rolling, simplifies the automated operation of seedlings, reduces manual intervention, and lowers the complexity and cost of operation.
