    A chain conveyor section of a longwall conveying device for underground mining of a longwall using a winning machine riding on the conveying device comprising a trough member defining a trough adapted to receive a scraper chain therein the trough member having one flanged side wall and one unflanged side wall positionable next to the longwall, a main rack section connected to the unflanged side wall extending over the trough and toward the flanged side wall for holding one end of the scraper in the trough, and an intermediate rack segment pivotally connected to the main rack segment for interconnecting at least the unflanged side wall sides of adjacent chain conveyor sections of the conveying device.

    one
    The invention relates to mining machines, namely, chain downhole, scraper conveyors used in underground mines as a transport means and guide for a mining machine with chainless feed.
    Known chain bottomhole scraper conveyor for - underground workings, including sections, joined to each other and having a toothed rail fixed to them from the dam side.
    However, the location on the bottom of the rack rail to move the mining machine does not allow it to be used on thin layers.
    The closest to the present invention is a chain downhole scraper conveyor for underground workings, including sections joined to each other with grooves for the lower and upper lines of the traction body, formed by the dam side and downhole side walls with the clamps of the upper branch of the traction body, and fixed to the side serrated rail with main segments of length less than the length of the section, and intermediate segments f2j overlapping the joining points of the sections.
    However, in this conveyor, the toothed rail is located on the zavalny side of the conveyor, which implies the location of the mining machine above the conveyor: yer in fairly powerful lavas. When low-power seams are operated, the height of the mining complex must be reduced, for which the mining machine must be located on the downhole side of the conveyor.
    Install the same toothed rail with
    15 of the downhole side of the conveyor above the clamping of the upper branch of the traction unit leads to an increase in the height of the conveyor and makes it difficult to load the mineral on it.
    20
    The aim of the invention is to reduce the height of the conveyor.
    This goal is achieved by the fact that in a chain downhole scraper conveyor for underground workings,
    25 which includes sections joined with each other with grooves for the lower and upper branches of the traction body, formed by the dam side and downhole side walls, with the clamps of the upper branch pipe, and the toothed rail fixed to the side with length of segments less than the length of the section, and the intermediate segments segmenting the pumping points of the sections, the clamps of the upper branch of the traction organ of the bottom-hole side wall are made of a toothed rail, the main and intermediate segments of which have strips facing the middle part and sections, with the main segments at the ends made of fork-shaped, covering the ends of the intermediate segments on both sides and connected to them by means of chain fingers, the main segments being provided with a beveled pinch-shaped section extending along all the downhole side walls of the sections.
    Fig, 1 schematically shows a section of a chain downhole scraper conveyor with a main segment; figure 2 - intermediate segment; Fig. 3 is a cross-section through the junction of a segment.
    The downhole scraper chain conveyor for underground workings contains sections 1 with grooves for the upper (working) branch and the lower (idle) branch of the traction body. The side wall 2 located on the cleaning side of the face, as opposed to the side wall located on the bottom side, does not have an upper flange.
    On the side wall 2 facing the clearing of the inlet, there is an attachment of the upper branch of the traction body, made of a toothed rail with the main segment 3, which is shorter than the section length.
    Between the two side bars 4 and 5 of the main segment 3 and the side bars B and 7 of the intermediate segment are fingers 8, which form a toothed rail with which the gear of the mining machine engages.
    The ends of the main and intermediate segments have holes 9 for entered. The day 10 fingers are used to connect adjacent segments. In this case, intermediate segments can be made with longitudinal length compensations. The intermediate segments respectively overlap the junction between the sections of the sections and thus also make a connection on the side of the clean-up of the conveyor section.
    Located on the side of the clearing bar of the main segments 3 for connecting forks clamp the end of the adjacent intermediate segment.
    5, 7 main and intermediate strips directed to the middle of the conveyor also serve as scrapers located on the side of the cleaning bottom
    the upper branch of the traction organ. From the intake side, this function is performed by the upper flange of the side wall of the conveyor.
    The main segments .3 are provided with an oblique, pinch-shaped portion of the loading platform 12, which extends from the side facing the clearing face down the length of the side wall of the conveyor portion. Bevel 13 this
    the loading platform section at one end, respectively, is longer than the section section, while the bevel 14 at the other end is slightly shorter than the section section. This ensures that the ends of the loading platform are sufficiently overlapped, even in a position deviated from the horizontal position, so that
    that the material extracted does not fall into the intermediate spaces.
    The main and intermediate segments 15 have the advantage THAT THEY can easily be replaced.
    The chain scraper conveyor with a toothed rail located on the side of the clearing side has a relatively small structural
    height. t- ..
    The design of the conveyor with the toothed rail located on the side of the cleaning side and the loading platform forms the support for the mining machine.
