Abstract
The utility model relates to a reverse-installation type toothed rail middle groove, and particularly relates to a reverse-installation type toothed rail middle groove for a scraper conveyor for thin seams. The reverse-installation type toothed rail middle groove is applied to the coal mine working face scraper conveyor. The reverse-installation type toothed rail middle groove is mainly used for solving the problems that a conventional middle groove of the scraper conveyor is high in toothed rail engagement and is not suitable for the mining of thin seam coal mine. According to the technical scheme, the reverse-installation type toothed rail middle groove comprises a middle groove body, wherein a reverse-installation type toothed rail seat is arranged on the middle groove body, and reverse-installation type toothed rails are arranged on the reverse-installation type toothed rail seat. Due to the adoption of the technical scheme, the reverse-installation type toothed rail middle groove has the advantages that the toothed rails are reversely arranged in the middle groove of the scraper conveyer according to special structures of the toothed rails, so that the height of a walking part of the scraper conveyer is effectively reduced, and the requirements of thin seam coal mining are satisfied.
Description
Technical field
The utility model relates to the anti-dress formula rack rails intermediate channel that a kind of scraper conveyor for thin seams is used, and it is for coal mine work area drag conveyor.
Background technology
At colliery down-hole combined mining working, coal-winning machine and drag conveyor support the use, and together with elevating conveyor, crushing engine, conveyor, hydraulic support, complete mining face under mine comprehensive mechanical coal mining and fortune coal.Common coal-winning machine and drag conveyor are applicable in exploitation, high seam.When running into thin seam mining, this just has certain requirement to coal-winning machine and drag conveyor, especially the requirement aspect height.For drag conveyor, require the rack rails engagement of intermediate channel highly low.
Summary of the invention
The utility model is high mainly for existing the middle pan of scraper conveyor rack rails engagement, is not suitable for exploiting the problem in girdle colliery, and a kind of anti-dress formula rack rails intermediate channel is provided.
The utility model is to address the above problem the technical scheme of taking to be:
An anti-dress formula rack rails intermediate channel, comprises intermediate channel, is provided with anti-dress formula rack rails seat in intermediate channel, on anti-dress formula rack rails seat, is provided with anti-toothing rail.
The utility model adopts technique scheme, according to the special construction of rack rails, in the anti-intermediate channel that is contained in drag conveyor of rack rails, effectively reduces the height of drag conveyor running part, has met the requirement of girdle coal mining.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the B-B sectional drawing of Fig. 1.
The specific embodiment
