AI Technical Summary

⚠Technical Problem

Existing fruit tree girdling and bark stripping tools typically only have one layer of girdling and bark stripping structure, requiring at least two girdling operations to peel off the bark, which is time-consuming and labor-intensive.

⚗Method used

A multifunctional girdling and girdling knife was designed, comprising a U-shaped plate, a horizontal shaft, a rotating plate, an arc-shaped clamping plate, a girdling blade, an opening and closing mechanism, and a girdling spacing adjustment mechanism. It can complete two layers of girdling and girdling in one operation, and the opening and closing of the clamping plate and the spacing adjustment are controlled by a motor and gear system.

🎯Benefits of technology

It enables precise girdling and bark removal of fruit trees, improving work efficiency and quality while reducing operation time and labor intensity.
