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.
