The utility model provides a milling machine, because of including the first aspect embodiment milling machine's milling drum system 1 that slowly changes, consequently have above-mentioned milling machine's milling drum system 1 that slowly changes's whole beneficial effect, do not state one by one here.
In the embodiment, a switch 40 is added to the milling drum slow-turning system 1 of the milling machine, and the milling drum 10 is driven to rotate at a low speed by closing the switch 40 and using a preset low current in the controller. When the engine 206 is lowered to the idle speed, the milling machine tail gate is opened, the change-over switch 40 near the tail gate is pressed, in order to avoid misoperation, the change-over switch 40 needs to be pressed for more than three seconds for starting, the main shaft of the engine 206 drives the pump 202 to rotate through the coupling 208, the pump 202 absorbs oil from the hydraulic oil tank 50 through the filter 60, high-pressure oil is output to enter the motor 204, and therefore the milling drum 10 is driven to rotate. Since the low current output module corresponding to the change-over switch 40 is preset in the controller, so that the opening degree of the pump 202 is at the low end, the output hydraulic oil flow is small, and the milling drum 10 rotates at a low speed.
