SU43619A1 - Mining harvester for preparatory and cleaning works - Google Patents

Description

The proposed mining harvester is intended for driving drifts and in the clearing holes in the coal deposits.

The machine performs the following operations: cutting the coal, breaking, loading the conveyor and loading the conveyor belt.

In FIG. 1 depicts a mining combine in a longitudinal vertical section; FIG. 2 - top view; FIG. 3 - rear view; FIG. 4 depicts the shape of a cut made by a combine.

The proposed mining harvester is equipped with a ring-shaped sliding bar 1, the cutting chain of which produces cuttings at the ceiling, from the sides and at the ground. At the corners of bar 1 there are shafts 4 fitted with augers 8 and having toothed crowns 6 for inserting sprockets 5 into the cut.

The cutting of coal from four sides in the proposed machine is carried out by the cutting chain of bar 1, running along the perimeter of the cross section of the passable production. The cutting chain is set in motion at the same time from four electric motors 2, which are located at the four angles of output and that drive through the corresponding gear (6)

tori 3 and shafts 4 stars 5, one in each corner of the development. To remove the notch barb from the slot and to place the sprockets 5 at the ends of the shafts 4, jagged crowns 6 are planted, cutting four holes 7 at the corners of the workings, in which the screws 8 are also placed, which are located in the cylinders 9 and serve to lead the barb.

If necessary, coal is fired using hydraulic jacking cartridges 10 located on the four edges of the ring bar.

Chopped and repulsed coal is piled together with the notch fines on the conveyor L2 with the help of paddles 13 of the Joy type machine, driven from the conveyor ropes 12 and the motors 14. The conveyor 12 can be bent in both directions up to 45 ° in horizontal plane, and It can be expanded from individual sections.

The movement and maneuvering of the machine is carried out with the help of four tracks 15, of which the lower two, each separately, are set in motion from its motor 14 by means of a hydraulic device consisting

from the stem 16 and the cylinders. a, the upper two caterpillars can be pressed with the help of ynpyrvix jacks 18 to the top of the reservoir, thereby creating sufficient traction with the soil.

The power of the firing cartridges, as well as the tracks, is produced from the pumps located in the chambers 19 and driven by the same electric motors 14.

The entire machine may, by means of the device 20, be applied to the bed of the formation. With the same cutting chain length, the bar can be pushed up by reducing the working width; You can also add the desired number of links of the cutting chain.

The subject matter of the invention.

Claims (2)

1. A mountain harvester for preparatory and cleaning works with an annular sliding bar, the cutting chain of which produces cuttings at the ceiling, sides and soil, characterized in that the shafts 4 located at the corners of bar 1 with screws 8 are equipped with gear crowns 6 for entering into the cut stars 5. 2. In the combine according to claim 1, use the upper tracks 15 (Figs. 1, 2 and 3) mounted on jacks 18 in order to press them against the roof to press on the lower tracks. s / -s / f, i / 22 to; IZYYE; W zyash2aashzhkshk2: zk§Zhyy2y РГ | iv): o 4i4 jV .: Г Н, й ..s4ia-: -  .-Yes ..f ga.:i; j% g;: j.jigjg5: gStesssX: aba: g .. ,,. ./r7 / S  V M G, and FG-, 1 / ...., .-- l..y v "- -j ;;; 3 ;; 2; SS S4 Sw% 2: i LJ ....-.- L-JO14:,.
