Abstract

The invention relates to the extraction of natural stone and improves the productivity of its sawing. The device includes a housing with cutters 7. The housing is made of a fixed 1 fixed in parallel with each other and movable 2 rings (K). Fixed K 1 is rigidly fixed by means of the bracket 3 to the stone, carved machine. The movable K 2 through gear shaft 4 is connected to the drive and rotates together with the bushings and the shaft gear 6 in them with face mills 7. During the rotation K 2, the drive gear shafts 6 are in engagement with the gear crown K 1 rotate around their axis. The milling cutters 7, which also rotate around the axis of the axis and planetary, perform propyl. In order to produce the longitudinal cutting, the device moves the sl along the bottom to the required distance. 2 Il. oo N5 SAD

Description

The invention relates to the mining industry and can be used in the extraction of natural stone both in mines and in open pits.

The purpose of the invention is to increase sawing performance.

FIG. 1 shows schematically the proposed device, the frontal section of FIG. 2 The peripheral part of the device, top view.

The housing of the device consists of a fixed ring 1 installed parallel to each other and a movable ring 2, the centers of which are on the same axis. The fixed ring 1 is rigidly fixed by means of the bracket 3 to the caliper of the stone-cutting machine and provided with a ring gear. The movable ring 2 by means of transmission through the shaft gear 4 is connected to the drive of the stone-cutting machine. On the movable ring 2 of the radialpo are fixed sleeves 5 with bearings that can be aligned with the ring 2. In the sleeves 5 are mounted drive shaft gears b, which are in engagement with the toothed crown of the stationary ring 1. - face milling cutters 7. On the base ring 2 between face milling cutters 8 are rigidly fixed.

The device works in the following um way.

The base ring 2 is driven into rotation by the shaft gear A, which is connected to the drive of the stone-cutting maip-p1y, and rotates around an axis relative to the fixed ring 5 and located in them vap gears with face mills 7. When the ring

2 drive shaft gears 6- with end mills 7 that are in engagement with the ring cog of ring 1 begin to rotate around their own 5 axis.

The device is brought to the bottom, installed vertically or horizontally and is fed to the bottom. I rotate, both around my own axis, so JO and planetary mills perform propyl. In order to produce longitudinal propyl, the device is moved along the slab for the required distance.

Obtained in the process of sawing

by cutters, the products of destruction of the stone fall into the space between the scrapers 8 and the cutter before it. The rotation of the rolling ring 2 provides the exit of the cutters 7 from the cutting and removal of the products of stone destruction.
