    A mineral mining installation has a longwall conveyor provided with a guide at the face-side thereof. A drive frame is provided at each end of the conveyor, and a plough is movable along the guide to win material from the longwall face. The plough is driven by a chain passing round a pair of end sprockets associated with the drive frames. The plough is constituted by a pair of plough bodies joined together by an intermediate member pivotally connected therebetween. Each of the plough bodies is provided with cutter bits and the intermediate member may also have cutter bits. The two ends of the plough driving chain are connected to the intermediate member, and the plough is of sufficient length to enable material to be won at least as far as each end sprocket.

    专利说明:

    The invention relates to plow installations Mg intended for coal extraction. A plow installation is known that allows coal to be excavated along its entire length, i.e. to the end of the lavas. The installation includes a plow and a face conveyor, along which the plow moves along a rail that goes to the drift. The plow chain is rotated in a parallel drift at approximately right angles to the cleaning face around the swivel wheels, with the drive wheel of the plow chain placed with the plow and conveyor drive in drift 1J. The disadvantage of this installation is that the parallel drift is forced by the downhole conveyor and by the plow and conveyor. Due to the turning of conveyor and strand chains from lava to drift, large tensile forces act on the chain, and this leads to strong wear of the chains and their guiding parts. Closest to the proposed technical essence and the achieved effect is a plow installation, including a conveyor with a guide mounted on it, on which a plow is installed, made of two organs, the chain of which is located on the downhole side of the conveyor and fixed on sprockets 2. A disadvantage of the known installation is an inability to position the star in the guide, and vypol | Nenie guide .privedet higher to lower loading spo lities, which generally lead to the removal zheniyu life. The purpose of the invention is to increase the service life. This goal is achieved by the fact that in a plow installation, including a conveyor with a guide fixed on it, on which a plow is installed, made of two working ojpraHOBs, the drawing chain of which is located on the bottomhole side of the conveyor and fixed on sprockets; sprocket and bent away to the side. FIG. 1 shows the final section of the plow installation, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1. Before the cleaning face (not shown, there is a downhole conveyor 1 consisting of a chain scraper conveyor, which becomes a pan made of separate chute sections that are articulated with one another with the possibility of limited displacement. With the conveyor pot coming through 2 There is a conveyor frame 3 in which a drive drum (not shown) for driving and rotating one or more scraper chains is located.The number 4 denotes a drum attached on the tab side for driving the conveyor chain. Fig. 1 shows a plow installation with a conveyor in the area of the auxiliary drive, i.e., in the area of the upper section of the drift of the clearing flank. The plow guide 5 is attached to the conveyor 1 on the clearing-side of the plow. bus bar 6 and loading platform 7, behind which two chain channels 8 and 9 for an endless chain for driving the plow are vertically above each other, reverse branch 10 is directed in the upper channel 8, and in the lower channel 9 - a branch of the plow chain 11 with which the strug is associated. Plow 12 has two sled-like plow bodies 13 and 14, which are connected to each other through an intermediate link 15. The connection is made through hinges 16 with horizontal horizontal lines extending vertically to the clearing face. Thus, a comparatively long structure is provided with sufficient maneuverability on bends and cross-country ability. Strong under compression and stretching, however, the intermediate link 15, made with the possibility of moving between the two plow bodies 13 and 14, is made as ralazok (Fig. 3). In so doing, the sled is guided along the pillar guide 5. They have two guide pistons 17 and 17 to which both ends of the chain of the chain branch 11 are connected. The junction points of the plow chain are located approximately in the middle of the pillar 12 in the longitudinal direction according to the direction of movement. Both plow bodies 13 and 14 have protruding plow cutters 18 relative to the place of contact of the chains, and cutters located one above the other at facing each other 19. The plow chain is driven from the auxiliary drive through the plow chain wheel 20, which, together with the entire drive 21 protrudes relative to the frame 3 of the conveyor 1 upwards and is connected to the end of the .paNfia 3 through the hinges 22. Thus, the plow chain wheel 20 is located at a smaller distance from the end of the lava relative to the drift border than the frame 3.
    The plow guide B at the end of the conveyor 1 is bent in the direction of the clearing face, so that between the conveyor, i.e. between the connecting chute 2 and the frame 3, and the bent part of the plow guide 5, there is a space 23 for the plow chain wheel, a bent part of the guide the plow passes laterally past the frame 3 and drive 21 plow and reaches 5 not far from the beginning of the lava relative to the boundary of the drift.
    In the bend zone, the plow guide 5 has, on the side facing the conveyor 1, behind the holes 24 and 25 for the passage of the plow chains {Fig. 3). Both branches 10 and 11 of the chain are pulled back from the direction of the channels 8 and 9 in the direction of the sprocket 20. Between the guide 5 and the upper part of the conveyor, special guide chains can be provided to achieve a perfect direction of the winding up on the sprocket 20 and winding up him chains.
    FIG. 1 that due to the connection of the plow chain to the middle of the plow 12, as well as sufficiently protruding plow cutters, the 18 plow can be advanced from the side past
    frame 3 and drive 21 plow. FIG. shows approximately the extreme position of the plow when moving in the direction of the arrow 5. At the same time, the plow cutters 18 work by clearing the face to the drift boundary, i.e. to a place located at a greater or less long distance from the rods, 3 conveyors. Thus, it becomes possible to mine
    0 lava interface area with drift to the end of lava.
    When mined in the direction of arrow S, the cutters 19 of the follower plow body 13 can mine the cleaning face for the cutters 18 of the plow org 14. In addition, there is a possibility of a slug-type intermediate link 15 to be equipped with mining devices.
    The proposed plow installation
    0 can also be used if the plow cannot be moved before the start of the lava and accordingly to the drift boundary, and if coal is pulled at the beginning of the lava, for example,
    5 driving a parallel roadway. Essential, first of all, is that the plow with its sufficiently protruding cutters 18 can extract coal in the region of the frame 3 and the sprocket 20.
