There are many parts for plate scraper in underground coal mine. One of them is called pin row of plate scraper, which is located in the middle part of the scraper conveyor and installed above the central trough.
Scraper pin row, also known as the scraper gear rail, scraper pin row, through the scraper and the central slot on the throne with horizontal pin, vertical pin fixed together, there are forging pin row, casting pin row, specifications and types are also a lot of coal mining face shearer walking track.
Scraping machine pin is similar to a train track, section by section scraping machine pin row are connected to form coal winning machine walking track, coal winning machine to walk on it to mining of coal wall, make peeling coal into coal winning machine, blowing machine pin row is scraper conveyor and the coal mining machine in the middle of the bridge, the two can work together.
The quality selection of the pin row of the scraper is also the basis of the normal operation of the whole fully mechanized mining face. Henan Shuangzhi machinery scraper accessories manufacturer has been focusing on the production and processing of scraper accessories, scraper pin pai forging castings are available, can meet the needs of customers for different coal mine working environment products.
Scraper gear track is also called pin rail, located in the middle of the scraper slot on the upper part, is the shearer walking track. It is designed to change the manufacturing process of pin rail from split welding, forging welding and integral casting to integral die forging. Can be selected according to the needs of the shearer, forging gear rail relatively long service life. Today we will learn about the plate scraper forging gear rail. The heat treatment process of forging gear rail is annealing + normalizing + tempering. Through heat treatment, the impact toughness, tensile strength and elongation of the material have been greatly improved, and the performance index has exceeded the design requirements, and the effect is good. The gear track of the scraper produced by Henan Shuangzhi includes: 11TXG147-6, 1CGT-1, TY-45, 1CGIII03, 3TY-72, 115S-01, 123s-01, 07txG126-6, 11TXG147-6, 3S001-00/7, DXB125*5, etc., welcome new and old customers to inquire.

The gear track of the scraper is installed on the gear track seat of the middle slot, which is the track supported and guided by the shearer. It is an important support point for the stability of normal coal mining for the shearer to realize the haulage of the shearer relying on the tooth and rail pin tooth of the scraper. Therefore, scraper conveyor parts manufacturers remind you to use a more durable scraper conveyor gear track. At present, the teeth and rails of the plate scraper in the market mostly adopt the structural forms such as integral die forging, integral casting, split welding and forging welding. Fission welding type rack and forge welding type rack is a compound structure, by putting the two track plate and pin gear processing compound into an organic whole, due to welding and machining accuracy cannot be guaranteed, so prone to open the phenomenon such as welding, fracture, wear, these two kinds of structure of the rack can't meet the need of the high-power coal winning machine supporting the fully mechanized coal face. Although the whole cast gear track avoids the problem of gear track cracking to some extent, the casting strength obviously fails to meet the use requirements, which affects the coal mining efficiency. The integral die forging gear track is strengthened by heat treatment of alloy structural steel. It adopts die forging technology and completes the manufacturing process by a series of procedures such as forging, forming, trimming and punching. Therefore, the overall strength of the tooth and rail of the scraper is higher than the above three technologies, the pin tooth position and tooth shape processing accuracy is more guaranteed, can make the shearer and the tooth and rail better mesh, the impact force in the use process is also smaller, for the large power shearer, conveyor supporting use to provide a guarantee. The integral die forged gear rail can meet the required performance requirements and is more durable. After reading, you choose and buy which scraper gear rail heart roughly spectrum! Henan Shuangzhi produces various types of gear rail forgings, scraper forgings, sprocket components, etc. If you want to know more, you are welcome to contact us in time.
