What Is Coal Shearer?

Performance Pharacteristics

The fuselage is divided into three sections through the high-strength hydraulic screw nut pair to form a rigid connection, high strength, convenient and reliable installation and disassembly.
The fuselage adopts bridge structure layout, effectively increasing the installed power and coal space, and reducing the plane height.

The special AC frequency converter adopts airborne speed regulation mode, which has wide speed regulation range, small size and high reliability.

Chinese color large screen graphic display, which can realize the man-machine dialogue interface of operation prompt, real-time display of equipment running status and fault diagnosis.

With power, leakage, overvoltage, undervoltage, overcurrent, temperature, water pressure, gas overlimit and other perfect protection and diagnostic functions.
The hydraulic system adopts highly integrated and reliable valve group system, which is simple, reliable and convenient to install and disassemble.
The cutting part is equipped with clutch device and elastic torque shaft, which can effectively protect mechanical overload and use operation.
The machine has large power, short, narrow and thin body size, and strong adaptability to the working face of thin coal seam.
The cutting motor is a single motor structure, with high life, strong stability and low failure rate.
According to the demand, the flip type arc coal baffle can be selected to ensure the coal loading effect
The shearer can upgrade intelligent control functions such as memory cutting and remote control according to demand
According to the demand, the shell and guide shoe can be upgraded with special materials and special heat treatment process, and the deformation, wear resistance and life are greatly improved.

After Sale Support

MG 200 / 455-BWD AC traction shearer traction, Strong hill-climbing ability, With the rationality and reliability of matching with the working face conveyor; Mechanical transmission part structure is simple and reliable, Easy to disassemble and install, The speed regulation system adopts airborne type, "one tow two", AC frequency frequency control type, The frequency converter is transformed based on ABB's 800 series products, Reasonable integration of the components, Reliable Performance, The controller uses industrial control computers, A 5.7-inch real-color display screen, Its operation interface is the Chinese interface, Can display the system voltage, cutting current, traction current, traction speed, traction force and other parameters and the relevant protection and operation parameters of the sheinterface, And has the fault display function.

Main Structural Features

The whole machine is multi-motor transverse layout and multi-point drive, with remote control from the machine, centralized station control traction and elevation, and the right manual control of the rocker arm, which realizes multi-point control and convenient operation.
The fuselage is the whole casting box with no docking surface, which avoids the loosening of the shearer.
The machine power is larger, the fuselage is short, narrow, thin, good adaptability for thin coal seam.
The electronic control system adopts industrial control computer combined with PLC to form the upper and lower position machine, which can easily set or screen all kinds of monitoring, detection, display and protection items.
The imported Harvey valve group is selected in the adjustment hydraulic system, with advanced performance, reliable and convenient operation.
The hydraulic lock and cylinder are split design to facilitate fault search, maintenance and replacement.
Two cutting motor is equipped with mechanical clutch device, maintenance is safe and convenient.
The guide slide boots are split type and easy to replace.
The machine is equipped with hydraulic anti-skid brake, which can prevent the shearer from using the working face of the large dip Angle (<15°), but when the coal seam dip reaches or exceeds 15°, the user should bring the hydraulic anti-skid winch synchronized with the walking speed of the shearer according to the provisions of the coal mine safety regulations.
