SU1240889A1 - Cutter-loader for selective excavation of coal and rock - Google Patents

Description

".

The invention relates to mining. in particular, for shearers for the selective extraction of coal and rock.

The aim of the invention is to increase the completeness of the excavation and to improve the quality of coal mined and simultaneously transport from the coal and rock in parallel streams. -. . . :

 FIG. 1 shows the proposed combine, view from the side of the dam; in fig. 2 - the same plan view; in fig. 3 is a view A of FIG. one; FIG. 4 is a view B in FIG. one.

The combine includes an electric motor-. Tel 1, feed mechanism 2, gear units of cutting parts 3 and 4, swing gears - rockers 5 and 6, screw working bodies 7 and 8. For transferring coal from the advancing screw to the staggered branch of the conveyor or to the second conveyor, each working body has screw screws. superheaters 9 and 10, which are driven in rotation through rocking gears 11 and 12, located on the dam side of the cutting parts of the combine. Screw conveyors placed in open gutters 13. 14 with discharge windows at the bottom of the rocking chair, they have movable channels 15 and 16, which cover the dead space under the swing rocking gears of the workers. Dp. the hydraulic troughs 17 and 18 are provided for controlling the movable troughs. The rocking gears of the working bodies are adjustable in height by the hydraulic claws 19 and 20, and the rocking gears of the miner loaders are controlled by the hydraulic jacks 21 and 22. Dp complete loading of both coal and rock auger workers The bodies have throw-over, loading plates 23 and 24. The harvester has supports with skis 25 vs 2 moving along the pick-up from the side of the bottom, and supports with skis 27 and 28 moving along a round Direction. Skis 27 and 28 have reverse grabs.

Combine works as follows ..

At the end of the lava, the harvester hacks into a new strip. Then, a screw overload 408892 is set against the front auger, the diameter of which is Aven of the removable reservoir thickness.

 Tel 9 on the rocking gear 11 using the hydraulic jack 21 at a height that provides normal overload of the coal from the working auger to the overload screw. 5 zhatel. Using the jack 17, the movable chute b is advanced under the rocking gear 5 of the working auger to the bottom. The lagging auger is lowered to the soil and prepared for excavation of the soil rock. The rocking gearbox 12 of the reloader 10 with the movable I. Rail 16 pushed in with the help of the hydraulic jack 2 is set to a convenient height 3 position that does not interfere with

15 coal and rocks under the coybain and off. The harvester is prepared for sni1 (the next strip of coal and rock. When the combine is operated, the coal that is beaten off by the auger is overloaded

0 through the extended chute under the rocking chair into the material handler through which the screw is transported and unloaded through the window to the branch of the conveyor with a horizontally closed chain

25 or to the second (loose) conveyor, and the rock from the lagging auger is loaded Directly to the downhole branch of the conveyor or to the first (downhole) conveyor. -In the first case, coal and

30 breeds are transported in different

Directions: coal to the conveyor drift, along the shaft to the vent, in | in the second case, in any direction, depending on the location of the pledge, through which the rock is laid into the developed space. After excavating the coal strip and notching the combine to a new strip, the working augers change places.

40 mi, the positions and loading cranes also change, and the cycle repeats.

When a roof rock is blown up, the advance cheek pulls the coal from the soil of the formation and loads it directly onto the downhole part of the conveyor or onto the first conveyor (the loader is switched off). A lagging auger beats off the roof rock, which falls on the sweeper, located in this case under the auger, and is transported through it to the extended movable chute, through it to the reloading screw and then through the window to the second conveyor or the second conveyor. In this case, the coal is transported by the first conveyor, and the rock by the second.
