    专利说明:

    The invention relates to a conveyor. transport, namely to the scraper scraper conveyors for underground works. The scraper conveyor scraper is used for underground works, including the upper part and the new parts connected to it, which have a horizontal plane of the connector, bed, closed and closed notches of the upper and lower parts for the flat chain link, with a groove and a protrusion on the connector. tlj. However, in this scraper, the plane of the connector of its parts protrude at the ends of the scraper. Therefore, the upper part of the scraper undergoes wear on the lower branch of the traction organ, while both the upper and lower parts of the traction organ wear out. Closest to the offer is a scraper scraper conveyor for underground works, including Nieacny jointed with a vertical bolts, the upper and lower parts with horizontal planes of the connector protruding at the ends of the scraper on its upper side with the possibility of covering the ends of the upper part with the ends of the lower part and located on the plane of the connector separated by an edge channels for horizontal chain links connected to vertical links ;. However, in this scraper the wear of its upper part is inevitable. It appears on the idle branch of the conveyor body, since the edges of the upper part of the scraper slide along the coating. In addition, the bolt connection of the parts of the scraper is subjected to a shear force. The wear of both parts of the scraper leads to a reduction in the service life of the scraper. The purpose of the invention is to increase the service life of the scraper. This goal is achieved by the fact that in the scraper scraper conveyor for underground works, containing interconnected vertical bolts of the upper and lower parts with the horizontal planes of their connector, protruding at the ends of the scraper on the top of it with the. parts, and the channels located on the connector planes and divided by the edge for the horizontal chain links connected to the vertical links, c. two sides of the channels on the plane of the lower part of the connector: the grooves passing along the scraper are made, and on the plane of the connector, the upper part has ribs located in the grooves, while the lower part has end protrusions with recesses, and the upper part has recesses for vertical chain links. The end protrusions and channels are made in the form of central and lateral while the central protrusions have a width less than the width of the lateral protrusions, and the central channels have a width greater than the width of the side channels. Figures 1 and 2 illustrate variants v of performing a scraper for a scraper conveyor for underground works with a single pulling chain; in Fig. 3, a scraper of a conveyor with two pulling chains, the lower part; in Fig. 4, a scraper, upper part; Fig. 5 shows the same in the assembled state, the upper and the lower part; Figure 6 shows the connection of parts of a scraper with one pull chain; Fig. 7: a unit for connecting parts of a scraper with horizontal chain links; on . Fig.8 - scraper, middle part. The scraper of the scraper conveyor for underground works contains the lower part 1 and the upper part 2. A longitudinal thread passes along the axis shown by the dash-dotted line 3. The scraper cleaves the bed for the horizontal section of the chain link, made of two parallel channels 4 and 5, separated by a central edge 6. The bed for the chain is divided into two equal halves by the horizontal middle section 7 of the plane of the connector, thereby providing comprehensive coverage horizontal chain link. The plane of the connector has two outer sections 8 and 9, partially rounded and extending in such a way that the plane of the connector extends onto inclined surfaces 10 or 11 in the end region on the upper side of the scraper 12. While the surfaces touching on section 7 of the plane of the connector, made flat, so that the middle section does not create a coverage of the upper and lower parts, on; sections 8 and 9 of the plane of the connector in the lower part 1 are in the same slot 13 and 14, and in the upper part 2 in the edge 15 and 16 adjacent to it in the groove, the plane of the connector passes in such a way that the holes 17 and 18, which are necessary for two bolt-bolt joints, which in turn are divided into two unequal halves 19 and 20. The bolts extend this way from top to bottom and are located further so that they are outside the described bed, i.e. In the least loaded ends of the scraper, In the variant shown in FIG. 2, only the ends of the scraper are changed, namely, they have vertical ends 21 It 22, while the KOHIUJ 23 and 24 have scrappers (Fig. Two converging inclined surfaces 25). and 26 and a round knitting surface 27. Shown on the lower part of the design so that it lies on the bottom of the gutter. The plane of the connector has medium, horizontal sections 7, so that in this, the area of the lower part is formed with flat surfaces 28 and 29 .The flat bone of the connector has reaching square The sections 8 and 9 and the upper side of the scraper are located at the location 30 and 31. Between the surfaces 28 and 29 there are halves of the groove 13 and 14 having the corresponding surfaces 28 and 29, in and 9 the horizontal lower section 32 and the obliquely flank Attachments 33. In the lower section 32 there are holes 1 and 18 in the lower part 1 for connecting bolts 34. Each of these bolts is provided with a nut 35 having a washer 36 to rest on a corresponding counter-surface in the upper half of the hole, a, the bolt rod is equipped with the corresponding g dexterous. Both channels for a chain are separated from each other by a rib 37 located in the middle (Fig. 3. This bed for a chain has two channels 38 and 39 (Fig. 3 for positioning the halves of the steel chain wire in the knees 40 and 41 of the horizontal chain link). Both bands 38 and 39 are separated by an edge 42 entering the cavity inside a horizontal link 43. In both vertical links x 44 and 45 chains, adjacent to the horizontal link 43, there are protein faces at both ends of the rib 4 } the projections 46 that serve as a support their sections of the Rounding off of the link 47 of the chain. The upper part (Fig. 4. has left-sided surfaces of the connector surfaces corresponding to the surfaces of the lower part. So, surfaces 48 and 49 correspond to surfaces 28 and 29 of the lower part. These surfaces are located in both the edges of the ribs 15 and 16, which are adjacent to the grooves 13 and 14. The upper halves of the 20 bolt holes are located in the web, so that the bed has a connector for the chain, and there are corresponding parts in the upper part. Channels 50 and 51 are longer than the corresponding cavals 38 and 39 in the upper part. Instead of the lateral projections 46, grooves 52 are provided, rounded accordingly to the rounded vertical links of the chain 47. The scraper is shown in FIG. 5 for upside down,. those. the lower part is located on the top. The lower part has a constricted lamellar surface of the abutment protruding into the bed area 53 for the chain. Adjacent to the openings 17 and 18, fastened with the backs 54 and 55 jiKpyrleny 56 and 57, the juice is formed. This juice serves as a wear. edges and a cleaning collar with which transport is improved The middle section of the scraper has connections for chain links clamped to connect the scraper to the chains of the chain-dragging element. To do this, in operation with a central chain, a central edge 58 is used, which is horizontally in the cavity: a central link is located. The rib 58 is formed on the central part of the ski, having on its upper surface on both sides the central channels 59 and 60. These channels have a constant cross section and are the same. They serve to place the rectilinear side of a horizontal link centered on the ribs 58 and horizontal links of a double central chain. These links are seated on the ribs 61 and 62, to which the side channels 63 and 64 are adjacent to the outside. At each end of the above-described ska, which forms the central part, there are end lugs located on one side of the edge. One end protrusion 65 and 66 are located at both ends of the central flap 58. The end faces of the ribs 61 and 63 are provided with side end projections 67-70. Each step also has a recess 71 (protrusions 67-70 or 72 (. Protrusions 65,, 66), since the recesses in the protrusions attached by edge 61 and 62 are identical., They can differ only by the notches 72 in the protrusions 65 and 66, attached to the central edge 58. The notches 72. already, since the projections 65 and 66 have a smaller width in the longitudinal direction of the scraper than the projections 67-70. The notches are also provided with a curvature 73. Both channels 59 and 60, located on both sides of the central the ribs 58 are wider than the channels 63 and 64 that are outside the war, and this is necessary because of the relatively large step 74 for the center chain (diameter of the steel bar of the chain is 30 km) and step 75 for the double central chain (steel bar of the chain is 26 mm;.; The horizontal center link 76 {Fig.6) of the double central chains 77 in the structural rounds of these links is structurally provided 360, while
    the coverage of the inner rounds is 90.
    The proposed implementation of the scraper increases its life
    service, only the bottom part of the service is manufactured; Leads replace only this part.
