Milling and digging machine is widely used in tunnel, culvert, construction engineering and rock excavation and other construction fields of mechanical equipment, with high efficiency, low cost advantages.
The existing metal cutting head uses cylindrical cutting teeth to cut the soil in contact and separate the soil to achieve the purpose of metal cutting. However, such milling and digging machines need to clean the separated soil material immediately when working, otherwise the metal cutting head will become too deep and cause adhesion to the soil accumulation. This makes it encounter a rock layer with high hardness, the metal cutting will not move, and it is easy to have a large gear cutting loss phenomenon, and there are great limitations in application.
