Abstract
The invention relates to a reversely-arranged toothed rail middle groove for a scraper conveyer for a thin seam. The reversely-arranged toothed rail middle groove is used in the scraper conveyer of a coal mine working face. The reversely-arranged toothed rail middle groove mainly solves the problems that due to the fact that a toothed rail of a middle groove of an existing scraper conveyer is high in meshing degree, the existing scraper conveyer is not suitable for exploiting coal mines in the thin seam. According to the technical scheme, the reversely-arranged toothed rail middle groove comprises a middle groove body, a reversely-arranged toothed rail base is arranged on the middle groove body, and a reversely-arranged toothed rail is arranged on the reversely-arranged toothed rail base. Due to the adoption of the technical scheme, the toothed rail is reversely arranged in the middle groove body of the scraper conveyer according to the special structure of the toothed rail, the height of a walking portion of the scraper conveyer is effectively reduced, and the requirement for thin seam coal mine exploitation is satisfied.
Description
Technical field
The present invention relates to the anti-dress formula rack rails intermediate channel that a kind of scraper conveyor for thin seams is used, it is for the coal mine work area drag conveyor.
Background technology
At the 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 present invention 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 present invention addresses the above problem the technical scheme of taking to be:
A kind of anti-dress formula rack rails intermediate channel, comprise intermediate channel, is provided with anti-dress formula rack rails seat on intermediate channel, on anti-dress formula rack rails seat, is provided with anti-toothing rail.
The present invention 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the B-B sectional drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of anti-dress formula rack rails intermediate channel, comprise intermediate channel 1, is provided with anti-dress formula rack rails seat 2 on intermediate channel 1, on anti-dress formula rack rails seat 2, is provided with anti-toothing rail 3.
Claims (1)
1. an anti-dress formula rack rails intermediate channel, comprise intermediate channel (1), it is characterized in that: be provided with anti-dress formula rack rails seat (2) on intermediate channel (1), be provided with anti-toothing rail (3) on anti-dress formula rack rails seat (2).
