The central trough of the scraper is mainly used as a channel for transporting coal. Usually a section of the middle groove is composed of two 1.5 meters long groove steel and two middle plates. After the two middle plates are welded to the groove steel, the upper and lower layers are formed, in which the scraper chain runs. The state has clear standards for the steel used to weld the groove top steel of the middle slot, while the middle plate is selected in accordance with the actual application, with ordinary 45 steel, 16 manganese, or other materials, and in order to increase the wear resistance, you can add welding wear strip above.

The middle trough of the scraper conveyor is one of the key parts of the scraper conveyor, and it is the fuselage of the scraper conveyor. Only the volume and quality of the scraper conveyor occupies about 70% of the scraper conveyor machine. Scraper parts manufacturer Henan shuangzhi below for you to introduce the scraper middle trough.
As an important spare part of the scraper conveyor, the middle trough of the scraper is not only the bearing mechanism of the material and the scraper chain, but also the important fulcrum of the hydraulic support. Each scraper is generally equipped with more than 100 middle slots, the length of the middle slot is mainly 1.5m and 1.75m two types. Therefore, the service life of the scraper and the transport volume are largely determined by the service life of the middle slot.
The middle slot is mainly made of the groove side and the middle plate. The material is mainly 16Mn and ZG30SiMn2 of high manganese steel.
According to the different manufacturing technology of the middle slot, the middle slot can be divided into welding middle slot, casting middle slot and integral casting middle slot.
According to the different structure of the central trough, the central trough can be divided into the open bottom middle trough and the back end middle trough.
The middle groove can be divided into the middle groove of the single and the middle groove of the double.
The central trough of the scraper is in direct contact with the material, coal gangue and scraper chain, which is easy to be affected by it and will cause scraping and wear for a long time. The middle plate, bottom plate and groove top of the middle slot are the most prone to wear. The main wear forms are abrasive wear, fatigue wear, adhesive wear and corrosion wear.
Henan Shuangzhi, as a highly praised scraper conveyor accessories manufacturer in the industry, improves the abrasion resistance of the central slot of the scraper by adopting wear-resistant materials and optimizing the surface strengthening technology of the central slot. About more coal machine accessories product information, please continue to pay attention. If you need coal machine parts, you are welcome to telephone consultation, shuangzhi service for you anytime and anywhere.
The material, processing method and working condition of the middle slot of the scraper can cause the wear of the middle slot. Next, henan Shuanzhi analyzed the influence of working conditions on the middle groove wear of the scraper.
Scraper central trough in addition to transport coal, but also bear shearer carrying load, push, pull hydraulic support when the lateral force and longitudinal force. When large coal and gangue block are stuck in the middle trough, the impact force and extrusion pressure will cause the wear of the middle trough.
Henan Shuangzhi improves the strength of the middle slot of the scraper, increases the reliability of the accessories of the scraper, and reduces the maintenance of the scraper by adopting the casting of high-quality alloy as a whole or the welding of steel groove, steel band and high-strength wear-resisting medium plate. If you need the middle slot of the scraper, you are welcome to contact us to verify more product information.
The middle trough of the scraper machine is also called the slop or trough is the fuselage of the scraper conveyer, which is composed of the middle plate and the groove side steel, etc. The upper trough to transport coal and the lower trough for the scraper chain to be fixed with bolts in the return journey. Double small series to take you to understand the scraper conveyor under the middle trough.
Scraper conveyer transport coal and other goods of the main carrier, the middle trough according to the production process to divide, can be divided into the welding middle trough and the casting middle trough. The welding middle groove is mainly composed of groove top steel and middle plate. There are two types of groove top steel, one is M-shaped groove top steel and the other is E-shaped groove top steel. As the name implies, these two types of groove top steel are shaped like capital letters M and E.
The central trough of the scraper is mainly used as a channel for transporting coal. Usually a section of the middle groove is composed of two 1.5 meters long groove steel and two middle plates. After the two middle plates are welded to the groove steel, the upper and lower layers are formed, in which the scraper chain runs. The state has clear standards for the steel used to weld the groove top steel of the middle slot, while the middle plate is selected in accordance with the actual application, with ordinary 45 steel, 16 manganese, or other materials, and in order to increase the wear resistance, you can add welding wear strip above.
Through the above description, have a basic understanding of the central slot of the scraper, Henan Shuangzhi production chute, scraper and other easy to wear parts, sprocket components new and repaired, structural parts. Welcome new and old customers to consult the factory.

Reducer has the characteristics of large bearing capacity, high transmission efficiency, generally used for input shaft and output shaft are arranged in a vertical direction of the transmission device.
For the coal mine scraper reducer oil leakage of the reasons are usually only two points: sealing ring damage and the box body joint surface is not strict. Most of the oil leakage of the scraper reducer is caused by the damage of the sealing ring. After long-term operation and the influence of underground coal mine environment, the sealing ring will inevitably wear down, resulting in poor sealing effect and oil leakage. However, it can be well solved by simply replacing the sealing ring. For the box body joint surface lax than the former slightly less, this situation is mostly the upper and lower box body lax, the end pressure cap is not tight, may be caused by the assembly irregularities, may also be caused by the long-term operation of bolts loose, the solution is to tighten all parts of the bolts.
Henan Shuangzhi machinery specializes in the production of all kinds of coal machine accessories: reducer 1 shaft assembly, 2 shaft assembly, 3 shaft assembly, 4 shaft assembly, etc., welcome to consult and cooperate!
The cross beam of the scraper conveyer is long strip in appearance and has threaded hole. The whole length, center distance and width of thread hole are different for different types of beam, and the matching bolts and nuts are also different.
The function of the beam of scraper conveyor is equivalent to that of E-type and U-type bolts, which mainly fix the scraper through single-head bolts to form the chain of scraper. In the middle trough, the chain scraper chain is driven by the sprocket shaft group to do circular movement to complete the coal transport.
Shuangzhi coal machine main various types of sliding scraper and supporting bolts, beams. The scraper is forged, its process is more complex, but also according to the customer to provide model, technical requirements, material processing and forging.
