Working principle of double-wheel slotting machine

The milling head part of the two-wheel milling machine is equipped with a certain number of sensors for collecting data. The operator can intuitively see the working status of the two-wheel milling machine (the straightness of the milling head) through the touch screen. milling depth, milling head resistance) and operate accordingly.

The slotting principle of the two-wheel milling equipment is to drive the lower two-wheel shaft rotation through the hydraulic system to carry out horizontal cutting, and use the reverse circulation to break the formation and produce ballast. The depth of the major trench can reach 150m and the thickness of the secondary trench is 80cm. Between 280cm.

The two-wheel milling equipment is mainly composed of two parts: lifting equipment, milling machine, mud preparation and screening system. Take the BC36 double-wheel milling machine produced by the German Bao'e company as an example. Its main working part is the milling cutter holder. The milling cutter frame is a steel frame with a height of 12m and a weight of 36 m. It has hydraulic and electrical control systems, and 3 hydraulic devices are installed in the lower part. The motors on both sides are arranged horizontally and respectively drive two milling wheels equipped with milling teeth. When milling grooves, the two milling wheels rotate at a low speed in opposite directions. Their milled teeth grind up the surrounding rock. The intermediate hydraulic motor drives the mud pump to discharge the drilling slag and mud mixture to the ground mud farm station through the sand suction port in the middle of the iron wheel. Centralized desanding treatment is carried out, and then the purified mud is returned to the tank section, and this cycle is repeated until the final hole is formed into a groove.
