Description

Hydraulic grinders are known for cutting coal blocks from the rear sight, equipped with jetting nozzles for cutting the cutting gaps along the horizontal 1 with two Htpikylny side faces of the detachable block.

The proposed hydraulic cutting machine, in order to cut the rear edge, is horizontally located and movable in a direction that is perpendicular to the machine feed direction, with nozzles, designed to form helical: water jets.

The movement of the pipe and its return to the initial position is carried out by means of a servomotor and a spring.

In FIG. 1 shows a longitudinal section of a hydraulic cutting machine; FIG. The second is in cross section and FIG. 3- in the form of soku.

The hydraulic cutting machine consists of a housing / in which .i channels for feeding nozzles are located. The nozzles 2 are located on the front end of the body, angled to it and

intended for cutting the slit in the horizontal plane. Nozzles 3 are used to cut the slot in the vertical plane.

For the block segments, the nozzles 4 located in the cylindrical tube 5, moving in the direction perpendicular to the machine feed direction, serve at the rear face.

The water supply to the nozzles 2 and 5 is carried out using the valve 6.

The water supply to the nozzles is made by means of the valve 7. The servo-motor 8 and the spring 9 are predetermined to drive the pipes 5 with Hiica shami 4.

The water is supplied to the body of the mashina by means of a hose 10, rigidly securing I to the hinge // giving it the ability to change the body.

11ri cut blocks are supplied to the bottom by a jet of water from horizontal nozzles 2 located at an angle to the direction of movement of the hull, cutting through the gap to the full width of the traverse of the machine; at the same time the nozzles 3, located vertically on the sides of the hull, give jets cutting in

The type of gap in the vertical plane.

For the first lower row of blocks, the machine feed is doubled; first along the lower part of the block planned for cutting to the full length of the machine body and secondarily on the upper part of the block. In the first case, the vertical nozzles cut the sykovy sides of the block from bottom to top, and when cutting along the upper part, these nozzles cut from top to bottom.

For sections of the block from the bottom, in the position where the machine at the top is brought to the limit of the cut, the valve 6 is turned off, and the valve 7 is turned on, whereby the water jets coming out of the nozzles 4 cut off the block at the rear edge.

A cut block of coal or other rock can be removed from the wand by a sheet of iron, planted in the lower shaft, under the block.
