AI Technical Summary

Technical Problem

Existing Angelica dahurica excavators are prone to root breakage or epidermal damage when digging directly after the stems and leaves have been cut off. Furthermore, the tangled roots increase the difficulty of digging and energy consumption, resulting in low efficiency.

Method used

A machine vision-based Angelica dahurica excavation system is used to excavate the first, second, and third excavation areas in stages. The system uses a clamping part to hold the roots of the Angelica dahurica and moves left, right, up, and down to gradually loosen the soil and pull out the Angelica dahurica, avoiding direct excavation that could damage the roots.

Benefits of technology

It improved the integrity of Angelica dahurica roots and excavation efficiency, reduced energy consumption, and reduced subsequent soil separation operations, thereby improving overall operational efficiency.

Abstract

The application discloses a Baizhi digging system based on machine vision and relates to the field of Baizhi digging. A second groove with a second threshold depth is dug in a second digging area. After the second groove is completely dug, a digging part is used to dig a third groove with a third threshold depth in the second groove towards a third digging area. After the third groove is completely dug, the digging part is used to dig a first groove with a first threshold depth in the second groove towards a first digging area. The first threshold is smaller than the second threshold, and the second threshold is smaller than the third threshold. After the first groove is completely dug, a clamping part is used to clamp a Baizhi root area, and a moving part is used to pull out the Baizhi. The system improves the preservation efficiency of the Baizhi root integrity on the basis of reducing the digging energy consumption, and further achieves the effect of providing the digging efficiency of the Baizhi.
