Description

Technical Field

[0002] In the current field of pavement maintenance, an economical and efficient strategy is to remove the damaged old pavement layer through milling technology and then lay a new covering layer. This process is usually implemented using a milling machine as a key equipment. It is widely used in the renovation of roads, urban roads, airport runways, cargo loading and unloading areas, etc. Milling machines can not only effectively solve problems such as pavement bulges, oil wave marks, network cracks and rutting, but also assist in the excavation of potholes and trenches.

[0003] The basic structure of a milling machine includes a drive mechanism (motor or engine), a main structure, a milling cutter, a depth adjustment system, and a travel device. When working, the motor drives the milling cutter to rotate at high speed, and the operator guides the machine to mill the road material through manual propulsion. Existing milling equipment is usually only equipped with a single type and specification of milling cutter, which means that milling operations can only be performed on a specific type of working surface at a time. When dealing with the situation where there are curbs on both sides of the old road surface, it is usually necessary to replace milling cutters of different sizes and types and then perform subsequent milling operations again. This practice not only consumes time and manpower, but also reduces construction efficiency and increases construction costs.

[0004] Therefore, it is necessary to study a ground corner milling device that can perform milling operations on a single working surface and on two different working surfaces at the same time. Utility Model Content
