Description

f

The invention relates to the processing of non-metallic materials, mainly natural stone and concrete, and can be used for the extraction of block stone from solid wood, cutting communication trenches in monolithic concrete pavements, etc., using disc tools, in particular diamond cutting discs.

The purpose of the invention is to increase productivity.

FIG. 1 shows schematically a stone-cutting device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - section BB on. one.

The device consists of a housing 1 on which a disk cutting body 2, for example a diamond cutting wheel, is installed with a drive 3, a support element 4. The sealing part 5 of the support element 4 is made in the form of an elastic plate 6, for example of rubber, which is attached to the support element 4 screws 7 and pressure bar 8 with a guide groove 9.

In operation, the sealing part 5, together with the disk-cutting member 2 and the surfaces formed during the cutting, forms a cavity 10 for supplying the coolant, since the resilient plate 6 contacts the slotted groove along the entire contour of the slot in the immediate vicinity of the cutting member.

On case 1, eyelet 1 is made to secure the winch cable, which is mounted on the cut array using anchors;

a side 12 for supplying and supplying fluid to the cavity 10 and to the disk cutting body 2 and the casing 13, which prevents splashing of the coolant 5 leaving the cutting zone.

The sealing part of the support element is set relative to the end of the disk cutting body with a gap of 1 / 500-1 / 10 of the height of the support element. The gap is selected according to the diameter of the disk cutting member and the height of the support member.

The device works as follows.

Before starting the operation, the device is mounted with the support element 4 in a special jig with a groove imitating a slot. A pump or gravity flow is connected to the sleeve 12, which is attached to the pipe 12, to the cavity 10 and to the disk cutting member 2. The drive 3 of the disk cutting member 2 is activated.

The working feed is carried out by a winch, the cable of which is fastened to the eyelet 11 of the stone-cutting device (the direction of flow is indicated in Fig. 1 by the arrow). As the feed progresses, the disk cutter 2 cuts into the array; to form a slot, which includes the support element 4 with the sealing part 5.

The spent fluid, along with the sludge, is ejected from the cutting zone tangentially to the disk cutting body 2, and pure water, falling into the guide groove 9 of the clamping bar 8, rushes into the jj cutting zone.

Claims (2)

1. A STONE-CARRYING DEVICE, comprising a housing on which a disk cutting organ is mounted, and a support element mounted in the plane of the cutting organ, cast in that, in order to increase productivity, it is provided with a seal that is attached to the support element by means of a pressure bar with a groove for the direction of coolant supply, while the distance between the seal and the disk cutting organ is 1 / 500-1 / 10 of the height of the support element. 2. The device according to π.1, with the exception that the seal is made in the form of an elastic plate. FIG. 1
