AI Technical Summary

Technical Problem

The existing milling drum milling cutter head has a simple structure, which makes it difficult to effectively turn over the road surface and affects milling efficiency.

Method used

A milling drum milling cutter head was designed, including a roller, a mounting block, a retaining post, a connecting post, and a cutter head. The cutter head has a drill bit at the bottom and is equipped with reinforcing ribs and protrusions. The roller drives the cutter head on the mounting block to perform milling, and the protrusions of the reinforcing ribs are used to turn over the road surface around the broken area.

Benefits of technology

It improves milling efficiency by further turning over the road surface around the broken area through the protrusions of the reinforcing ribs, thus solving the problem of low efficiency caused by the simple structure.
