    The invention relates to chain scraper conveyors for mining enterprises. The purpose of the invention is to increase the degree of interchangeability of parts and reliability of the section by increasing the rigidity of its structural elements. Figure 1 shows a section of a groove of a chain scraper conveyor for mining enterprises, a transverse section; FIG. 2 shows a side profile of the section disassembled with two variants of the upper V-shaped rolled section, the cross-section in FIGS. 3-4 is the same when assembled; Figures 6, 6 and 7 show various options for making and joining the bottom with intermediate shelves of the side profiles; Fig. 8 is a side view of the gutter; in fig. 9 - the junction of the upper and lower sheets bottom, bottom view; in fig. 10 is a section A-A in FIG. 9 (rotated); Fig. 1 is a sectional connecting strap, side view; in fig. 12 is a section BB in FIG. 11. The chute section of the chain scraper conveyor for mining companies includes side profiles 1 and a metal bottom, 2 on which a working body with at least one centrally located chain 3 or with two side chains 4 is located. Each side profile 1 contains a lower V -shaped katanuiz profile part / 5 and the upper V-shaped rolled profile part 6 shsh The lower profile parts 5 are made with the lower 8 and the upper 9 shelves arranged parallel to each other and equal in length. The upper profile parts 6 and 7 are filled with the lower 10 and upper flanges, the same as the shelves 8 and 9 k, directed to the center of the section. The bottom shelf 8 is the bottom side profile shelf 1, while the top shelf 9 together with the bottom shelf 10 corresponding to the upper section 6 or 7 forms the intermediate shelf of the side profile I. The top shelf 11 of the upper section 6 or 7 is the top flange of this side profile 1. Profile I of the lower profile part 5 is a standard rolled profile with which the uneven profile of the upper profile part 7 can be combined or another profile of the upper profile hour 6. In this case, the lower profile part 5 is made so that its internal profile is suitable for choice both for guiding the scrapers attached to the side chains 4 (figure 5) and for guiding the scrapers attached to at least one centrally located chain 3. The inner surface of the lower flange 8 has a flat section 12 in transverse section, which is inclined to the horizontal at an angle approximately equal to 19 ° and extends from the inner surface of the wall 13 to the inflection point 14. The segment 15 between the inflection point 14 and free butt ohm 16 shelves 8 sloping towards the horizontal at an angle of about 9. The section 15 of the inner surface of the lower flange 8 of the lower V-shaped rolled section 5 is designed for flawless. river direction of the external circuits of the working body 4. The upper shelf 9 of each lower V-shaped rolled section 5 is made with bend 17 to the internal surface that is located above bend 14. Section 18 between the internal surface of wall 13 and bend 17 is inclined to the horizontal at an angle , approximately 35 °, while the section 19 between the bend 17 and the free end 20 of the upper flange 9 is located approximately horizontally. The indicated angles of inclination are chosen for the 4o side chains most rapidly moving in the gutter section. It is understood that the angles of inclination of surfaces 12 and 15, respectively 18 and 19, can be different for the corresponding round link chains. Here, first of all, it is important that the angles of inclination of the inner surface of the shelves 8 and 9 to the horizontal in the areas between the bends and the ends of the shelves 8 and 9 are smaller than its angles to the horizontal. The zones between the bends and the wall of the lower profile 5 are made below. the outer side in the transition region between the wall 3 and the upper shelf 9 with a rolled profile recess 21. To the outer side of the wall 13 of the V-shaped profile part 5 is attached a connecting strip 22, which also functions as a supporting element. Each connecting strip 22 is fixed on the outer side of the lower section 5 with the possibility of its upper edge being located above the surface 23 of the upper flange and the section 5. Each connecting strip 22 is formed with at least one longitudinal edge 24 on its inner side, which is inserted into the profile recess 21. In addition, the connecting strips 22 are connected to the profile parts 5 at points 25 and 26 by welding. The upper profile part 6 consisting of a rolled profile is applicable only for guiding the scrapers if they are attached to a centrally located chain 4. Its upper flange 11 is made shorter than its lower flange 10, which consequently projects beyond the end of the upper flange 11, the internal profile the surface of the part 6 serving to the direction of the scrapers is formed by two internal surfaces 27 and 28 converging to the wall of the profile part 6. The surface 27 is inclined to the horizontal at an angle equal to 19, and the surface 28 is at an angle equal to 30 °. The magnitude by which lower shelf 10 is longer than upper shelf 11 is approximately equal to the distance from kinks 14 and 17 to free ends 16 and, respectively, 20 mating shelves 8 and 9 of the profile section. Top profile part 6. is welded to the connecting plan at point 29 22. In addition, the lower shelf 10 which is supported on the upper shelf of the profile part 5, at point 30 is welded with the upper shelf 9 of this profile part 5, the upper profile part 6 is made on its outer side in the transition region between its lower shelf 10 with rolled product The recess 3.1, which, together with the profile recess 21, forms a grophilic recess of the side profile, extending over the length of the gutter section and closed by the interposer 22, the connecting strip 22 terminates under the upper shelf 1I of the upper profile part 6. It extends approximately from the middle of the lower profile part 5 to a distance approximately equal to the height of the transition region between the wall of the upper flange 11 of the upper section 6. FIG. 4 shows the side profile of the gutter section, which is formed from two identical profile parts 5 and 7. Also here, the upper profile part 7 is supported by its lower horizontal shelf IO on the upper shelf 9 of the lower profile part 5. Since the upper profile part 7 has a large height than the height of the section 6, the weld 29 is located approximately at the height of the middle of the top section 7. The side profile according to FIG. 4 is intended for the gutter sections, which are used in scraper conveyors with two side chains. As with the side profile shown in Fig. 3, and with the side profile shown in Fig. 4, the upper profile part 6, respectively, the profile part 7 with the outer side of its profile wall abuts against the protruding connecting strip 22, Fig. 5- 7 shows various embodiments and connections of the metal bottom 2 with intermediate shelves of the side profiles 1. According to the first embodiment (FIG. 3), the metal bottom 2 is made in the form of one durable metal sheet. 32, the thickness of which is equal to the sum of the thicknesses of the ends of the shelves 9 and 10 of the profile parts 5 and 7, Metal, sheet 32 of the bottom 2 is welded at points 33 and 34 with both shelves 9 and 10, The other side profile of the gutter section is respectively complete and welded accordingly to the metal sheet 32 bottoms 2.. The metal bottom 2 can be made in the form of the upper 35 n lower 36 sheets arranged one on another without a gap. In this case, the bottom bottom sheet 36 is connected to the upper shelves 9 of the lower profile parts 5 by welding. The thickness of the sheet 36 corresponds approximately to the thickness of the upper flange 9. The upper metal sheet 35 of the bottom, the thickness of which is approximately equal to the thickness of the lower flange 10 of the upper part 7, can be welded between the two lower shelves 10 of the upper profile part 7, but it can also function as a metal the sheet working on wear and established removable with a possibility of replacement. Also, the upper metal sheet 35 of the bottom can be firmly welded to the lower shelves 10 of both upper profile parts 7. The lower sheet 36 of the metal bottom welded to the upper shelves 9 of both lower profile parts 5 forms, together with these profile parts 5, a guide box for scrapers lower branches. Accordingly, the metal bottom welded to the low shelves 10 of the two upper profile parts 7 forms, together with these parts 7, a guide box for the scrapers of the upper branch. Both guide boxes for sherkhney scrapers and lower branches of the traction body could be firmly and inseparably connected to each other by welding 37 parts 7 with two connecting strips 22 in place. Also the upper guide box formed by the upper V-shaped sections 7 and the bottom bottom sheet 35, which is welded to them, can be detachable and a replacement can be connected to the lower guide box by means of bolts 38. Horizontal bolts 38 pass through the holes provided for them in the walls of the V-shaped profile s parts 7 and in the connecting plankyh 22. And each bolt 38 is horizontal with skoschennoy head 39 is placed in the hole kotor1a upper rolled V- shaped profile portion 7 is flush with the inner surface. Bolts 38 can be fixed in the holes by means of gulls 40, which are screwed onto the bolts 38 from the outside of the side profiles 1.
