What are the main parts of the shearer? What do the parts do

The shearer model is represented by the following letters: M-shearer G-drum type 650-cutting section power 1710-**machine power W-chainless D-electric traction type shearer, depending on the thickness of each layer, the coal seam is below the meter, MG150-345 model can be used, and the above can be 435,700. Shanghai Daqi Mine Electromechanical specializes in the production and sales of coal mine shearers (including open-pit shearers), roadheaders, conveyors and other equipment and accessories, and the specific contact manager 13916206820

The shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce manual labor, improve safety, and achieve the purpose of high yield, high efficiency and low consumption.

The shearer is divided into sawing, planing, drilling and milling: the shearer is a large-scale complex system integrating mechanical, electrical and hydraulic, the working environment is harsh, if the failure will lead to the interruption of the entire coal mining work, resulting in huge economic losses. With the development of the coal industry, the functions of the shearer are more and more, and its own structure and composition are more and more complex, so the reasons for the failure are also complex.

The double-drum shearer integrates the successful experience of thin coal seam shearers at home and abroad, and is a new type of high-power thin coal seam shearer designed for China's specific national conditions.

Pro, modern shearers are generally divided into hydraulic traction and electric traction shearers, under normal circumstances, the ordinary mechanized coal mining face uses hydraulic traction shearers, and the comprehensive mechanized coal mining uses electric traction shearers, of course, this is not absolute. The shearer is easy to use a drum to cut coal, and there are generally two kinds of single drum and double drum. Because the shearer cuts coal because the drum is a left-handed or right-hand rotating drum, the cut coal is brought to the scraper conveyor (the shearer sits on the scraper conveyor, and meshes with the scraper conveyor pin row through the walking wheel, and is driven by the traction spike comm).

The coal is transported to the ** machine at the lower outlet through the scraper conveyor at the working face, and then through the scraper conveyor in the lower lane or directly to the belt trouser lead conveyor.

The coal is transported to the ** machine of the lower shot Jingkou through the scraper conveyor of the working face, and then through the scraper conveyor of the lower roadway or directly to the belt conveyor.

Hello dear and happy to answer your <>

The specific requirements for the shearer are: (1) The productivity should meet the requirements of the output of the coal mining face. (2) Make full use of the tension effect of the coal wall, so that the energy consumption is low, the lump coal rate is high, and the coal dust is less; It has the functions of crushing and loading coal, self-opening incision, automatic height adjustment and tilt adjustment.

3) It can realize stepless speed regulation and automatic speed regulation to adapt to the change of coal hardness and give full play to the efficiency of the shearer. (4) All electrical equipment should have explosion-proof performance, with overload, leakage, overvoltage, overtemperature, gas overrun and other protection functions. Liquid cracking (5) There should be reliable anti-skid and braking devices, spray dust reduction devices, towing cable devices, etc., to prevent the machine from sliding and improve the working environment.

6) The coal mining machinery should also adopt modular design and building block combination to achieve remote control, with memory, working condition display, fault diagnosis, Wajing Zhengsi pre-cutting and other functions. (7) It has sufficient strength and high reliability to meet the requirements of intensive production and high yield and high efficiency of mines. (8) It is easy to operate, convenient for underground transportation, disassembly and maintenance.

A1Hydraulic traction: The traction motor drives the hydraulic pump to transmit the high-pressure oil to the hydraulic motor through the pressure regulating system and through the high-pressure pipe. Through the gear set deceleration, the rail wheel is driven to rotate, so that the shearer rides on the scraper conveyor.

2.Electric traction inverter and motor or electromagnetic governor and slip motor or reluctance governor and reluctance motor, through the gear set deceleration to drive the rail wheel to rotate, so that the shearer rides on the scraper conveyor.

The plow is used to mine thin coal seams, and I think it seems to be about 1 meter of coal seams

The working process of the shearer is:

At the same time that the left and right cutting drums rotate, the shearer moves left or right along the coal wall, the shearer keeps moving, the cutting drum rotates continuously, the coal is constantly cut off from the coal wall, falls on the scraper conveyor at the bottom of the shearer, the scraper conveyor transports the cut coal out, because the coal block cut by the cutting drum is sometimes too big, the scraper conveyor can not be transported, so there is a crushing drum on the shearer, which is used to crush the large coal mine. Due to the different thickness of the coal seams, it may be necessary to adjust the front and rear cutting rollers up or down in order to cut the coal seams of different thicknesses.

The working process of the shearer mentioned above is the main function that the shearer must have, and the shearer must provide mechanical power for it to complete these actions, and these powers are provided by the motor, so the control of the shearer action is to control the rotation, speed change, commutation and stop process of the motor.

Let's talk about the electric motors that power these main movements:

1. The rotation of the left cutting drum is powered by the motor M4.

2. The rotation of the right cutting drum is powered by the motor M5.

3. The shearer moves left and right, which is completed by the left and right traction motors M2 and M3.

4. The power of the rotation of the crushing drum is provided by the motor M7.

5. The raising and lowering of the left and right cutting drums are completed by the hydraulic system, and the power of the hydraulic system is provided by the motor M6.

The main work of the coal mining electric control system is to control these motors and other protection functions.

Workflow?? It is to mine coal while hauling.
