Abstract

The invention relates to a coal mining device and particularly relates to a coal blocking device for a fully-mechanized coal mining machine of thin seams. Since a middle groove of a thin seam mining working surface scraper conveyor is relatively shallow, a coal passing space is small when the coal mining device is assorted with a thin seam mining machine, and meanwhile, coal overflows from a chute in a coal loading process to increase the float coal cleaning work amount. The coal blocking device for the fully-mechanized coal mining machine of thin seams comprises a spill plate, as well as a connecting base, a walking part and a side connecting plate, wherein one end of the connecting base is connected with the coal mining machine, the other end of the connecting base is connected with the walking part, the two ends of the base on the bottom of the walking part tilt up to form piston shoe shapes, a gear is arranged in the walking part, and is engaged with a scraper conveyer gear rail; the side connecting plate and the spill plate are respectively arranged on the two sides of the connecting base. The coal blocking device provided by the invention has the advantages of small volume, simple structure, convenience in operation, good safety, strong adaptability and the like and generates no effect on the normal work of the coal mining machine, so that the coal blocking device is widely suitable for random matching with coal mining machines with various model numbers.

Description

technical field [0001] The invention relates to a coal mining device, in particular to a coal retaining device for a thin coal seam fully mechanized coal mining machine. Background technique [0002] The characteristics of thin coal seam coal mining face are: thin coal seam and narrow working space. In order to meet the geological conditions of the thin coal seam, the supporting equipment is relatively compact in design. Among them, because the middle groove of the scraper conveyor on the working face is relatively shallow, there is a problem of small coal passing space when it is matched with a thin coal seam shearer. At the same time, when coal is loaded, there is a phenomenon that coal overflows the chute, resulting in an increase in the amount of floating coal cleaned. It increases the labor intensity of workers, prolongs the regular cycle time, and reduces the advantages of comprehensive mechanized mining. Therefore, it is of great significance to study the coal retai...
