Abstract
The utility model belongs to the technical field of coal mine equipment, and relates to a coal wall side pin row seat structure for an underground coal mine scraper conveyer middle trough, in particular to an improved structure for a low height pin row seat scraper conveyer middle trough. The structure comprises a baffle, a middle plate, a sealing bottom plate, a rump pan and a pin row seat. The structure is characterized in that the pin row seat is arranged on the lateral face of a rump pan on the coal wall side of a work face, and a guide device enabling a coal mining machine traction wheel to walk on the ramp plate side is arranged on the baffle. The coal wall side pin row seat structure for the underground coal mine scraper conveyer middle trough solves the technical problem of height limitation of the scraper conveyer and the coal mining machine in mining of a thin seam work face, and reduces the height of a matching machine face of the coal mining machine and the scraper conveyer. The pin row seat is welded on the ramp plate, the coal mining machine traction wheel can walk, and the requirements for the factors of the height of the middle trough and the like are reduced. The novel structure which is reasonable, reliable in performance and strong in adaptability is provided for a matching scraper conveyer of a large power coal mining machine.
Description
Technical field
The utility model belongs to the coal mine equipment technical field, is specifically related to a kind of intermediate channel of coal mine lower scraping plate conveyer, especially the improvement structure of low clearance pin row seat The middle pan of scraper conveyor.
Background technology
The pin row seat of existing coal mine lower scraping plate conveyer intermediate channel structure is positioned at baffle plate ledge side, so the intermediate channel whole height is limited, and the very difficult requirement that can satisfy girdle use heavy scraper conveyor.
Summary of the invention
The purpose of this utility model provides a kind of improvement structure of improved coal mine lower scraping plate conveyer intermediate channel, i.e. intermediate channel rib side pin row holder structure.
The utility model is achieved like this: coal mine lower scraping plate conveyer intermediate channel rib side pin row holder structure, comprise baffle plate ledge, middle plate, back cover plate, shovel board ledge, pin row seat, it is characterized in that the pin row seat places the shovel board end cut side of working face wall side, baffle plate groove is helped the guiding device that is provided with to walk at the shovel board skidding for the shearer haulage wheel.
The structure that the utility model adopts, solved the technical problem of thin seam working surface exploitation middle scraper conveyer and coal-winning machine height restriction, reduced the supporting machine height of coal-winning machine and drag conveyor, the pin row seat is welded on the shovel board, shearer haulage wheel walking can be provided, reduce the requirement of factors such as intermediate channel height again, for thin seam mining uses that the supporting drag conveyor of high-power coal cutter provides rationally, dependable performance, a kind of new structure that applicability is strong.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the utility model embodiment conveyer intermediate channel rib side pin row holder structure.
Among the figure, 1-baffle plate ledge; The 2-back cover plate; Plate among the 3-; 4-shovel board ledge; 5-pin row seat; The 6-guiding device.
The specific embodiment
