AI Technical Summary

⚠Technical Problem

Existing weed cutters can only chop up weeds on the ground, but cannot effectively remove the roots of weeds, causing them to regrow and affecting the growth of sand onions.

⚗Method used

A rotary weeder for planting sand onions was designed. It adopts a weeding fork and a linear telescopic mechanism. The weeding fork is inserted into the soil and flipped upward to scoop out the roots of weeds. Combined with a serrated strip and an adjusting ring, the separation efficiency is improved. The rotation and telescopic movement of the weeding fork are realized by a drive motor and a gear set.

🎯Benefits of technology

It effectively removes the roots of weeds from the soil, preventing weeds from competing with sand onions for nutrients and water, and improving the growing environment for sand onions.
