[0002] Currently, an economical and efficient pavement repair strategy is to use the milling technology. First, the damaged old pavement layer is removed, and then a new overlay is laid. In this process, a milling machine is mainly used for milling operations, which are widely used in renovation projects of highways, urban roads, airport runways, and cargo handling areas. It can not only effectively solve common problems such as pavement bulges, oil waves, reticulated cracks, and ruts, but also assist in the excavation of potholes and ditches.

[0003] Traditional milling machines usually consist of a main structure, milling cutters, a depth adjustment system, and walking wheels. During operation, the motor drives the cutters to rotate at high speed, and the machine is guided to mill the pavement material by pushing and pulling manually.
