5.Structure
Roadheader consists of below parts: cutting system, shovel system, 1st conveyor, main body, walking system, rear support system, water system, lubricating system and electrical system.
5.1
Cutting system
Cutting system consists of cutters, reducer and motor.
The cutter head is conical and has 41 cutting teeth spirally around its circumference.
Reducer is a type of planetary reducer.
5.2
Shovel system
The shovel system is composed of main shovel plate, side shovel plate, shovel plate driving device, driven wheel and so on. Through two hydraulic motors to rotate three tooth star wheel to load material onto the first conveyor.
Shovel system
Star wheel and motor.
5.3
1st conveyor
Drawing for 1st conveyor
1st conveyor driving device
5.4
Main body
Main body equipped with pumping station on right side, control panel on left side, cutting head in the front, shovel system and 1st conveyor at bottom. Walking system on left side bottom and right side bottom, support unit at rear.
5.5 W
alking system
The walking system mainly consists of several parts: hydraulic motor, reducer, track chain, tensioning pulley, tensioning cylinder, track frame, etc.
Braking system
Driving gear, track chain, reducer and motor.
5.6
Rear support
The function of rear support is to reduce vibration during operation and improve stability.
5.7
Hydraulic system
Hydraulic system is composed of various cylinders and motors, control panel, pump station and hoses.
5.8
Water system
The water system is divided into internal and external spray waterways.
Note: Before cutting, the cutting head must start the internal spray, otherwise the nozzle will be blocked and the dust suppression effect will be affected.
