Description
Technical Field
[0001] The utility model relates to the technical field of scraper conveyors, in particular to a floating coal recovery device for a return air laneway in a thin coal seam working face and a scraper conveyor. Background Art
[0002] The mining height of thin coal seams is generally between 1.1m and 1.3m, and the height of the drift is generally above 2.2m, so that the working face and the drift form a step of about 1m. When the mining machine drum moves to the head of the scraper conveyor, most of the slag can be pulled away by the transfer machine, and when the mining machine moves to the tail of the scraper conveyor, the slag will cause a large amount of floating coal to accumulate in the return air roadway. Manual cleaning alone will consume a lot of manpower and delay normal production operations.
[0003] Generally, a coal retaining plate will be installed at the tail of the scraper conveyor for thin coal seam working faces. When the mining machine moves to the tail of the machine again, a part of the coal can be thrown to the working face using the roller to minimize the amount of floating coal falling into the tunnel. This not only fails to solve the problem from the root, but also has poor compatibility with the mining machine, and the mining machine roller often cuts the coal retaining plate.
