Coal mine scraper conveyor beam also known as the pressure plate, is a scraper conveyor on a component. The working position of the beam of the coal mine scraper conveyor is located in the middle part of the scraper conveyor. The chain and the scraper are fixed together to form the scraper chain by cooperating with the single-head bolt. Therefore, the function of the beam of the coal mine scraper conveyor is the same as that of the E-bolt and U-bolt. The scraper chain is placed in the central trough of the scraper conveyor, and is driven by the sprocket assembly and other driving departments to transport coal operations. Henan Shuanzhi production of plate scraper beam, complete models. Provide drawings that can be customized
The cross beam of the scraper conveyer is long strip in appearance and has threaded hole.

The dumbbell pin plays an important role in the normal operation of the scraper conveyer as the connecting member between two adjacent chutes. Today the coal machine parts manufacturer Henan shuanzhi will introduce the dumbbell pin of scraper conveyer for you. Scraper conveyor dumbbell pin shape is like "fitness dumbbell", the middle is thinner, thicker at both ends. The dumbbell pin jams the ends of the two adjacent middle slots by the thicker ends at each end and connects the two adjacent middle slots by the thin middle rod. In addition to the common dumbbell pins described above, there are two types of special shaped dumbbell pins - I-type dumbbell pins and day-type rings. The stress condition of dumbbell pin is more complicated. In the process of hydraulic support moving the middle trough, the dumbbell pin will be pulled by the adjacent middle trough and subjected to shear stress because the adjacent chute is not synchronized. The dumbbell pin of scraper conveyor is a vulnerable part, and the common fault is fracture. The first crack occurred in the neck of the dumbbell pin, mainly because the neck of the dumbbell pin is a region where stress concentration is relatively large. Under long-term working conditions, the dumbbell pin's neck crack growth area diffused to a certain extent, resulting in fatigue fracture, resulting in the fracture of the whole dumbbell pin. Once the dumbbell pin is broken, it will cause the middle slot dislocation or off, the scraper chain is affected by it, easy to break the chain, the chain clip, from the chute off the phenomenon, affecting the scraper conveyor working surface production safety and normal production. Above is the dumbbell pin on the scraper conveyer, do you know? The dumbbell pin of the scraper conveyer produced by Henan Shuangzhi is forged from the selected material of 40Cr, and the quality is comparable to that of the original products after multiple processes such as tempering and quenching.

Scraper conveyer is one of the main equipment for conveying coal in fully mechanized coal mining face, and the central trough of scraper conveyer is the fuselage component and material bearing mechanism of scraper machine, so the central trough of scraper machine also has an important effect on scraper machine. We all know that the scraper conveyor is mainly composed of the nose, tail and fuselage. The main body of the scraper conveyor is the central trough. The performance of the scraper 105S07 central trough directly affects the service life of the scraper conveyor. The central trough of 105S07 bears the severe friction of coal, scraper and chain in the process of coal conveying. The middle trough of the scraper conveyer 105S07 is also the fulcrum of the hydraulic support moving in the fully mechanized coal face. Due to long time wear and tear, consumption is large, so scraper conveyor central trough is also the daily purchase of coal mine more scraper accessories. Because the scraper conveyor has different types, such as light, heavy, super heavy points, so for the scraper conveyor trough structure requirements are also different, so that the scraper conveyor trough category is also divided into several, such as welding central trough, casting welding central trough and integral casting central trough; Open bottom middle slot and back bottom middle slot; Middle canal of single bedded ear and middle canal of double bedded ear, etc. Although scraper conveyor 105S07 central trough structure is relatively simple, but it does not mean that it is not important in the scraper accessories, no matter the weight, no matter the size, scraper accessories have their own role and significance. So Henan Shuangzhi machinery has been all the same, no matter what scraper accessories pay attention to product quality, start from small details, so as to make the overall scraper conveyor normal operation.
