Problems solved by technology
[0003] For the thin coal seam working face, excavation along the tunnel requires a certain thickness of rock layer, which is difficult and expensive, and the rocks excavated also affect the coal quality. Therefore, reducing the height of the tunnel is of great significance to thin coal seam mining. Reprinted along the tunnel The height of the machine must also be reduced accordingly

The invention relates to the technical field of coal mine machinery, in particular to an intermediate drive type trough scraper loader used for a trough of a fully mechanized coal mining face of an underground mine. The intermediate drive type trough scraper loader is composed of an unloader headstock 1, an elevated segment chute 2, an intermediate drive rack 3, an inclined lift segment chute 4, a landing segment chute 5, a tailstock 6, a handpiece unloading chain wheel 7, a scraper 8, a round-link chain 9, a main driving chain wheel 10, a redirection chain wheel 11, a tailstock chain wheel 12 and other components. The intermediate drive type trough scraper loader is characterized in that the main driving chain wheel 10 is located on a landing section of a middle body of the loader, and a redirection driven chain wheel is installed on the headstock. The intermediate drive type trough scraper loader has the advantages that the overall height of the loader is reduced, the height of the trough is reduced, and the workload of tunnel excavation is reduced correspondingly; meanwhile, the height of a driving portion is small, and maintenance of components such as a speed reducer, a motor and a chain wheel assembly is facilitated.
Description
technical field [0001] The invention relates to the technical field of coal mining machinery, in particular to an intermediate drive type scraper transfer machine for trough use. Background technique [0002] The traditional trough loader for the fully mechanized mining face in underground coal mines is driven by a motor, and the motor, reducer, and main drive sprocket are all installed on the head frame of the scraper loader to form the drive assembly of the head, and the head frame It falls on the tail of the trough belt conveyor connected with the reloading machine. Because the head drive assembly of the loader is bulky and heavy, and the tail of the belt conveyor that supports it is required to have sufficient strength, the head of the loader is relatively high, and the hoisting and maintenance of the motor and reducer also require a certain height Space, which requires that the fully mechanized mining face must have sufficient height along the trough to meet normal pro...
