Thin seam combined coal mining unit as well as coal mining machine and scraper conveyer

Abstract

The invention discloses a thin seam combined coal mining unit as well as a coal mining machine and a scraper conveyer. The thin seam combined coal mining unit comprises the coal mining machine and the scraper conveyer. The coal mining machine comprises a body, a cutting part and a driving part, wherein the driving part is arranged on the side of a rib of the body; the scraper conveyer comprises a front side plate, a rear side plate and a scraper chain and a chain wheel arranged between the front side plate and the rear side plate. A pin track of the coal mining machine is arranged outside the front side plate, and the driving part is engaged with the pin track of the coal mining machine. According to the thin seam combined coal mining unit provided by the invention, the coal mining machine and the scraper conveyer are matched on the side of the rib, so that the height of the body of the coal mining machine can be reduced so as to reduce the coal mining height of the coal mining machine, so that the unit is easily arranged in the working face of the thin seam to more effectively explore aiming at the characteristic of height of the thin seam, thereby improving the extraction efficiency. Meanwhile, the maintenance space of the coal mining machine can be enlarged to facilitate maintenance work, the labor intensity of underground operators is reduced, and the operating safety is enhanced.

Description

technical field [0001] The invention relates to coal mining technology, in particular to a thin coal seam combined coal mining unit, a coal mining machine and a scraper conveyor. Background technique [0002] On the one hand, the combined coal mining units currently used in coal mining mainly include coal shearers, scraper conveyors, hydraulic supports and equipment trains. The driving wheel of the shearer is matched with the pin rail set on the scraper conveyor, and it reciprocates on the scraper conveyor. At the same time, the cutting part of the shearer is used to cut the coal seam to complete the coal dropping and coal loading functions; the scraper conveyor will The coal is transported to the conveyors on both sides of the shearer, which is convenient for transporting the coal out; the top of the hydraulic support supports the top of the coal seam, and at the same time, the bottom of the hydraulic support is connected with the scraper conveyor, which can push the scrape...
