What are the main components of a coal mining machine?
Coal mining machine is not often seen in our lives, but its main role we all know is the main tool for coal mining, coal mining machine is essential, the following for you to explain the main components of the coal mining machine.
Coal mining machine is mainly composed of four parts: electric motor, cutting section, traction section and auxiliary devices. The electric motor provides the power to drive the cutting section and traction section through the transmission mechanism, which provides the coal mining machine with the power required for dropping, loading and running along the working face. The cutting section completes coal dropping and loading, while the traction section makes the machine walk, and the auxiliary devices include spraying device, anti-skid device, and cable dragging device, etc., which are used to ensure the safe and reliable work of the coal miner. There are other big parts such as rocker arm of coal mining machine, left and right traveling section, left and right traveling box, shell of coal mining machine, left and right cutting section, electric control section, left and right hauling section, roller of coal mining machine and so on.
When several main parts of the whole coal mining machine are driven by a common motor, the motor becomes the main independent part of the coal mining machine, which is usually called the main motor. Generally the main motor has output shafts at both ends, one end driving the cutting part and the other driving the traveling part. It adopts a box structure and is connected to the adjacent parts through fastening bolts to form the body part of the coal mining machine. The motor needs to be explosion-proof. Modern coal mining machine motors are water-cooled, and most of them are stator water-cooled.
After the rocker arm is used, the nozzle on the coal arm side of the upper part of the rocker arm wears out and in some cases sticks the iron to the nozzle. The nozzles are made of copper. Take special care when repairing these parts. Do not cut them with acetylene, but chisel them out bit by bit and then tap them with an electric drill. If you cut with acetylene, the wire holes will be destroyed because the copper will melt at high temperatures and it will not be possible to remove the nozzle as a whole. In addition, the wire hole will be damaged during the melting process, which will affect the maintenance of the wire hole.
The above is the whole content of this introduction, I hope it will be helpful to you!
