SU1252486A1 - Cutter-loader for separate excavation of complex seams with filling-up - Google Patents

Description

The invention relates to mining equipment and is intended for the separate excavation of complex mineral layers.

The purpose of the invention is to increase the efficiency of laying the mined-out space and simplify the design of the combine.

1 shows a combine, a general view; FIG. 2 shows a schematic depiction of a laying device, / view along the axis of a tape scoop; figure 3 - section aa in figure 2. The proposed combine contains FIG. I, an electric motor I, gears 2, feed parts 3, a front cheek 4 mounted on a movable handle 5, a rear screw 6 mounted on a movable handle 7, a leading screw 8 on the handle 9, a folding device 10. The latter contains | - (Figures 2 and 3): a bucket chain conveyor II and a belt thrower 12.

Bucket chain conveyor II consists of drive chains 13 with non-penetrating 1 "in the buckets 14, drive sprocket 15 coaxially fixed on the leading screw 8, tension deflecting sprockets 16, casing 17. Belt thrower 12, pivotally mounted on casing 17, consists from the drums 18 and 19, which bends around the endless band 20, and the casing 21.

The thrower 12 is mounted on the casing 17 by means of a hinge 22 and a hydro-cylinder 23. The drum 18 is driven, and the drive is an electric motor 24 (FIG. 1). Handle 9 has a hydraulic jack 25, and handles 5 and 7, respectively, hydraulic jacks 26 and 27.

The combine works as follows.

The working stroke of the coybine is in the direction of arrow B. At the same time, the auger screw 8 is oriented along the interbed of waste rock (halite in this case), destroys it and transports the broken rock mass (rock) into the lower part of the casing 17 (Fig.Z), where it is buckets 14 and is transferred to the upper part of the casing 7. Here the rock is poured out of the buckets 14 and falls onto the moving belt 20 of the scooper 12. The belt 20, moving with great speed, podhvattya rock and

with force throws it in the direction of the goaf. The speed of the tape 20 is designed so that the rock, when thrown, is thrown out of the lining, and its flight trajectory goes inside the overlap, made in the form of a full box. Dp adjustments to the angle of inclination of the flight path (or to change the angle of inclination of the thrower 12) serve as a hydraulic jack 23.

The bucket conveyor I1 is driven from the leading screw 8 via a drive sprocket 15, which is mounted on the screw coaxially and fixed to it. Due to this, a separate drive for the conveyor is not needed. The asterisk is made paired and consists, in essence; of two asterisks connected by rigidly longitudinal elements arranged along a circumferential circumference. In the stream of each of the two stars there is a traction chain, to which the shovel 14 is attached, which seizes the rock and lifts it up to the place of discharge. The attachment of the buckets 14 to the chains 13 is carried out, for example, by the method of attaching the scrapers to the chains of the scraper conveyor (not shown).

The advanced screw 8 excavates the rock by an amount equal to the length of the part of the screw that is equipped with -. Noah incisors. The second conveying part of the screw, the length of which is equal to the width of the bucket conveyor 11 (or the drive sprocket shigin), does not excavate the rock (therefore, it is not equipped with cutters), but has a helix height corresponding to the diameter of the screw cutting part along the cutters. Such execution of the leading screw provides more efficient delivery of the broken rock from the cut to the area of its capture by the buckets of the bucket conveyor. Screw 4 digs the upper productive layer of the formation, screw 6 draws the lower layer and loads all broken ore onto the conveyor.

The orientation of the advanced screw 8 on the rock interlayer is made using a hydraulic jack 25. The ability to rotate the handle 9 relative to the handle 5 enables orientation regardless of the position of the pin 4.
