Description

the invention was not related to machines for cutting shell stone from an array in underground holes by means of horizontal, vertical and rear cuts with a flat head with bars, fixed on a sun port, laid a curtain mounted on a carriage, laid up on the back of the curtain shaft, laid on a vertical rack, mounted on a carriage, the running device, with the electric drive Oarov. Famous machines of this type for the back; Cuttings require significant work to be done when the machine is buried in the face, from those with a decrease in yield from the rock mass.

In the machine according to the invention, there is a head with bars, connected to the suport with a hinge with a horizontal axis and the state of the hinges of the parts connected together with a sharif, the axis of which is split into two legs and parallel to the guide rails. c) it allows to reduce the amount of preparatory work and to take out the in-depth mountain mass only on the basis of the bottom of the bar, not the whole maliina, entered into the chest. As a result, the yield of a stone from a hill is enlarged. The best results were observed when the axis of the electric motor for rotating bars, connected to the drive shaft of the trunk of bars, was directly located: the ken in one plane with the horizontal axis of the head rotation so that the shaft of the trunk and Hiapnnp connecting the knives to the knives could be cut with a knitted hook and connected to a horizontal shaft. coaxially

The cutting head of the machine according to the invention consists of two U-shaped parts. One of them is adjacent to the support and the joint connected to it, has a horizontal axis, and on the other, connected to the first joint, the axis of which is open, the electric motor is mounted on the inside of the U-shaped support, on the inside side of the U-shaped hinge. drive bars, and from the outside - the trunk, carrying bars and the mechanism of their fan-shaped dvplhenn. Another feature of the opsap cutting head, which is made by a double bar with a bar moving along the trunk, is that the bar closest to the head is shorter than the other so that in the Kpaih-ieM (lowered) position it is not connected to the drive shaft; This makes it possible to use it as an indicator of the position of the working bar or helix cutting.

FIG. 1 shows a general view of the machine; ) and FIG. 2 - kinematic scheme of the machine; ka fig. 3 - view of the front side with rear cutting; in fig. 4 –pasolol: enne bars, hrn, for rear cutting in horizontal section; in fig. D) - rasiliozhene bars at the rear of the river, side view in section.

In the drawing: kahr you are the following designations: (fig. 1) (1) - frame; (2) - caterpillar, (3) - jack; (4) - vertical (5) - mechanism of vertical nodachi; (0) - the mechanism of holizontalpy feed; (7) - caliper ve: -Sticking feed; (8) - U-shaped slide carriage; (9) - the mechanism; fan dvilse and; (10) - fan movement; (C) - trunk,., (12) - non-forward trunk bar; (13-) - bar moving along the trunk, shorter; (14) - management pools; (15) -j driver seat; (16) - hinge of the Sunnort (Fig. 2); (17) - swivel head; (18) - H-shaped movable part of the head; (19) - Elec1: Rodvigatel for driving bars; (20) - wood wiring (Fig. 3, 4, and 5); (21) - the position of the bar during the recess for the rear rezkn.

The frame is mounted on the rear frame (1), which can be mounted on the tracks (2) and fixed in place with a jack (3). A vertical frame (4) is mounted on the bottom frame (1), which can be moved relative to the bottom frame in a horizontal direction by means of the mechanism (5). In the guides of the helical (4) mechanism (C), the sunnort (7) moves with the U-shaped carriage (8), on which the mobile part of the head (18) is located. The mobility of a portion of the chuck (18) is achieved by using hinges (16) and (17). An electric motor (19) for driving the bars, connected to the drive shaft of the trunk (11), on which the bars (12) and (13) and the mechanism (9) of the fan-shaped House 10). The cutting bar (12) is attached at the end of the trunk (11). In part of the trunk (11), it blended; e to the head (18), a mobile but trunk bar (13) was numbered, made shorter. Bar (13) is positioned so that in the extreme extended position it is taken out of engagement with the trunk shaft (I) and in this state it is used not as a releasing bar, but as an indicator of the working bar's poloshiny (Fig. 3, 4 and 5).

The machine cuts at the bottom of the chest first vertical and horizontal cuts, which, in order to avoid premature breaking off, are reinforced by inserting depot pads into the horizontal slots (20).

In order to produce vertical cuts, based on the half open in FIG. 2, the iodine U-shaped part of the head (18) is rotated by 90 ° around the hinges (17) (upper and lower) in the horizontal plane (normally the plane of the drawing) in one direction or another (to us from our side of the drawing) depending on which (left or right) side of the face cuts, c. Then turn the bars {12) and (13) around the axis of the trunk (11) by means of the mechanism (9) to the horizontal position,

moreover, they bump the chest. Further, in a horizontal position, the bars, together with the head (18), are raised and the plates are lowered and shifted to the sunlort (7).

In order for horizontal cuttings, based on the above-described nolol,: Enn for vertically cutting, the head (18), rotated pa 90 ° around the axis (1G) in one direction or another, depending on whether the top or bottom part of the slab is cut . The way of working is the same as described.

In order to produce MALES1

Four to five stones were poured out of the chest at the bottom of the chest to bring the bar into position (21) (fig. 3) and the machine was moved forward.

The electric motors (19) and (10) are then launched, relaxed, and the bar chain (12) is driven in two directions, at the same time the bars (12) and (13) rotate around the axis of the trunk (11), crashing into the array and cutting off it previously cut stones. . Combined onsannye dvil; Enn with head feed in a vertical naravlenni and frame - in the mine by a means of mechanisms (5) and (6), reach the full development of the ready-made layer of horizontal and vertical cutting.

The machine is concentrated on the console (14) and is used by the driver, the nuish on the machine itself.

Mashppa is intended for the extraction of shell rock with a hardness of 10–30 kg / cm in close underground flank with a width of at least 2.5 m, but it works in quarries. Molset cut the machine for a change from 12 to 15 m of piece stone, for example, dimensions 490X240X190, 390X190X190, 510X250X215 or large monoliths, which are limited by the length of the bars and the possibility of extraction.
