    A guide assembly for a curved conveyor section of a scraper-chain conveyor guides the scraper assembly from a first straight conveyor portion round the curved conveyor section to a second straight conveyor portion. This guiding is accomplished by a pair of independently rotatable pulley wheels. A further pair of independently rotatable pulley wheels are provided to guide the drive chain of a plough round the curved conveyor section. This enables the plough to be driven to and fro along the first straight conveyor portion by a drive station attached to the second straight conveyor portion adjacent to the guide assembly.

    This invention relates to plow extraction of coal or other minerals. A plow installation is known, which includes a curved conveyor with a deflecting device, a plow, traction bodies of the conveyor and plow, at the conveyor water and plow. The disadvantage of such a plow installation is that the plow does not provide coal extraction along the entire length of the clearing face. The closest to the technical essence of the solution is a plow installation / including a curvilinear conveyor and a plow with deflecting mechanisms, a conveyor body in plow C21. The disadvantage of this design is the placement of the deflecting mechanism on the end portion of the fresh-side from the side of the bottom. With this arrangement, the plow cannot be moved directly to the deflection mechanism. As a result, a relatively wide lower niche should be provided at the entrance to the clearing face, which reduces the efficiency of the plow installation. The aim of the invention is to increase the efficiency of the plow installation by mechanizing the excavation of the lower niche. The goal is achieved by the fact that in a plow installation, including a curved conveyor, a plow, traction conveyor bodies and a plow, and a deflecting mechanism, the latter is made in the form of an axis; the conveyor body and the spacer roller, while the ring rollers for the conveyor body are located between the ring rollers for the plow body and have a diameter smaller than the diameter of the ring rollers for the plow body. FIG. 1 shows a top view of the plow installation in the zone of the lower part of the clearing slab; in fig. 2 is a view of the plow installation from the side of the bottom, and the deviation of the mechanism is shown in section. Strugov installation consists of a downhole conveyor 1, which became consisting of separate, pivotally interconnected linear
    sections. Downhole conveyor 1 is made in the form of a chain scraper conveyor. The delivery direction is shown in FIG. 1 by the letter B. By placing the conveyor in the mating zone, the lavashtrack is rotated o / 9O, with the deviation mechanism 2 located on the inside, connected to the curved linear section 3 becoming one node.
    The deflecting mechanism 2 consists of an annular body 4 in which two rollers 5 and 6 are placed one above the other with a roller or ball connection with the possibility of free rotation around a common vertical axis. The radius of the rollers 5 and 6 corresponds to the inner radius of curvature of the conveyor rod. Both rollers 5 and 6 form in the upper and lower branches of the chain scraper conveyor 1 a lateral restriction on the curve section. They are provided on the upper circumference with pocket-shaped profile grooves corresponding to the profile of the ends located on the belt 7 of the scraper chain and marked on. 2 numerals 8 scrapers, so that scrapers 8 get a reliable direction and support to freely rotating rollers 5 and 6 when passing the curve. The drive of the endless belt 7 of the conveyor belt is at the end of the conveyor section 9 that is not shown in the drawing.
    The RO extending parallel to the cleansing face or coal face 10. A curved conveyor section 11 of the curved conveyor is guided by a pillar 12. It moves along a guide 13 located in the conveyor 11 section from the side of the deflecting mechanism 2, namely from the side of the bottom. The 13 plow guides have chain channels located one above the other, in which the upper 14 and lower 15 branches of the plow body are placed.
    The upper 14 and lower 15 branches of the TAG of the plow body are deflected by deflecting rollers 16 and 17, which are designed to freely rotate around the common vertical axis of both rollers 5 and b of the deflecting mechanism 2. In addition, their diameter is smaller than the diameter of rollers 5 and 6. The deflecting annular rollers 16 and 17 may also consist of spoked wheels or annular rollers supported on rotating supports. Deviation A circular ring 16 for deflecting the upper branch 14 of the plow body is located above the rollers 5 and b of the deflecting mechanism 2, while a second deflecting ring roller 17 for deflecting the lower 15 t of the plow body is located under the rollers 5 and 6 .
    In order to leave the upper and lower branches of the traction body out of the chain channels of the plow 18 to bring both deflectors to the height of the rollers 16 and 17 of the deflecting mechanism 2, an expansion roller 19 is installed between the upper and lower branches. the deflector mechanism 2, the plow chain 14, 15 is directed around the drive star 20, which is driven by the drive 21. This drive 21 is flanked towards the conveyor section 9 in the delivery direction behind the deflector mechanism 2.
    The excavation of reservoir 22 in the direction of arrow A is carried out in reverse, after the lower drift 23 extends to the boundary of the section. In the above-mentioned plow installation, the plow 12 can be moved directly up to the deflecting mechanism 2 A loading casing 24 is attached to the conveyor on the side of the cleaning slab for loading coal carried by the strugo 12 onto the conveyor. In the inner part 25 of the diverting mechanism 2, drains and the like can be installed. to secure it.
