Description

The invention relates to equipment for the extraction of wall porridge by the open method.

Mechanisms and machines are known for cleaning wall stones extracted by stone-cutting machines, including two two-roll supports moving along the rails connected by a crossbar, in the lower part of which a monorail is fixed, along which the telpher with a mechanical gripper is moved to lift and unload stones outside the rails.

Since such a machine moves along the same rail lines as a stone-cutting machine, the width of the flanking trench should be increased by the length of the frame support, i.e. about 4 m. Such an increase in the width of the flank trench significantly reduces the use of mineral resources and significantly increases the laboriousness of the low-mechanized production process of trenches.

The aim of the present invention is to reduce the width of the flank trench required when operating a stone harvesting machine.

this is achieved by the fact that the frame supports interconnected by means of a bolt with directions of xcimi are made l-shaped with retractable rollers mounted on pivotally attached to frame supports movable in the vertical plane beams.

Figure 1 shows the machine in

working position; Fig. 2 shows the same in the inoperative position with raised rollers and extended support.

The machine contains a front L-shaped frame support I, on which

mounted drive roller 2, hinge beam 3 with roller 4, strut 5, hydraulic cylinder 6 lifting beam 3 and sliding console 7 with screw support 8, rear L-shaped frame

qnopy 9, bolt 10 with direction

II for locking the liJ carriage with a gripper 13 and a frame with driving mechanisms of the machine. The console 7 is suspended on the brackets 14 so that when the machine is operating, it is pressed against the flat bearing of support I and slightly protrudes beyond the limits of the track. When not in use, when the machine stops over the flank trench with raised rollers, the console extends far beyond the track, without interfering with the movement and

stone cutting machine 15.

The stone-cutting machine, cutting off a strip of stones, returns to the initial position by a maneuvering stroke and at the same time, by means of a special plow, moves the strip of cut stones from the bottom to the distance required for the entry of the jaws of the gripper 13. Following the stone-cutting machine it moves a machine.

The worker of the stone harvesting machine is as follows. The grip 13 is lowered, the bag is compressed (b-8 pieces of stones and pushed down. After lifting to a predetermined height, the machine runs along the rails by a step and

the stroke of the carriage 12 along the guides. At the point of unloading, the carriage is stopped, the grab is lowered, stones are unloaded and lifted, after which the carriage is returned to the loading position. Cycles can occur automatically until the strip of stones is completely cleaned along the bottom.

At the end, the machine is stopped, the console 7 is extended, closed with a strut and fastened with a screw support. After that, having released the struts 5, with hydraulic cylinders 6 they lift the beams 3 of both supports I and 9 with rollers 4 to the inoperative position and the stone-cutting machine continues cutting, ice rinks
