Generally, a floor milling machine consists of an engine, a frame, a milling rotor, a milling depth adjustment device, a hydraulic component, a material collection conveying device, a steering system, and a braking system.
The milling rotor is the main working part of the floor milling machine. It consists of a milling rotor shaft, a cutter seat, and a cutter head. It is in direct contact with the road surface and achieves the purpose of milling through its high-speed rotating milling cutter. The floor milling machine is equipped with an automatic leveling device, which uses the milling rotor side cover as the milling reference surface to control the two positioning hydraulic cylinders to keep the given milling depth constant;
The hydraulic system is used to drive the milling rotor to rotate, the whole machine to move, and the auxiliary device to work. It is mainly a closed hydraulic system with multiple pumps that are independent of each other. They do not interfere with each other during operation and have high reliability;
Some floor milling machines are equipped with tilt adjusters as needed to control the inclination of the rotor; generally, large floor milling machines have a collection and conveying device composed of a conveyor belt and a collector, which can collect and convey the milled bulk materials to the randomly moving carrier vehicle. The height of the conveying arm can be adjusted and can be swung left and right to adjust the unloading position.
When the specifications and models of floor milling machines are different, their structures and layouts are slightly different, but the basic working principles are the same or similar. The route of power transmission of milling machines: engine hydraulic pump hydraulic motor, hydraulic cylinder working device.
