Abstract

Use: extraction of sawn stone from the massif contoured by flanking trenches. SUMMARY OF THE INVENTION: A stone cutting machine comprises a chassis, a saw carriage and devices for producing longitudinal and horizontal cuts. The saw carriage is mounted for movement on the chassis. Devices for the production of longitudinal and horizontal cuts are placed on the saw carriage. The cutter contains two vertical saws to separate two rows of stones from the array. Vertical saws mounted on the shaft. The shaft is kinematically associated with the engine. One of the vertical saws has a larger diameter than the second vertical saw for producing transverse kerf in the lower ledge to its height. The device for producing horizontal kerf contains a horizontal saw for cutting two rows of stones. The horizontal saw is mounted on a shaft kinematically connected to the engine. 3 il. (/) WITH

Description

The invention relates to wall stone mining equipment.

A stone cutting machine is known, comprising two horizontal and two vertical parallel saws, one vertical saw being located relative to the second vertical saw and two horizontal saws in such a way that it produces vertical cuts in one ledge of the two-step slab, while the other saws cut stone into the upper ledge, previously prepared by the specified vertical saw.

The disadvantage of this machine is the complexity of the design, increased metal consumption due to the presence of an additional complex assembly for the production of vertical kerf in the preparatory step and a large number of auxiliary operations that reduce its productivity.

The closest to the present invention is a stone-cutting machine, including a chassis, on which a saw carriage with horizontal and vertical circular saws is mounted for movement,

The disadvantage of this machine is low productivity due to the possibility of cutting the cuts in only one step.

The purpose of the invention is to increase the productivity of the sawmill

stone from the flanked trench of the massif by reducing the time spent on auxiliary work on the production of transverse cuts.

This goal is achieved by the fact that the stone-cutting machine includes a chassis, on which the saw-carriage is mounted so that it can move, and placed on the saw-carriage a device for producing longitudinal cuts in the form of a shaft of two vertical saws fixed to the motor kinematically connected to the engine from the array and a device for the production of horizontal cutting in the form of a horizontal saw shaft fixed on the kinematically connected with the engine for cutting two rows of stone second, with one of the vertical saws it has more Th. the second vertical saw, the diameter for the production of transverse kerf in the lower ledge to its height.

This design of the stone-cutting machine allows simultaneous separation of the stone from the massif and cutting of transverse cuts on the underlying step.

FIG. 1 shows a stone-cutting machine; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2

The stone-cutting machine includes a chassis frame 1 moving along rails 2 with a saw carriage 3, on which the receiver 4 of the horizontal saw 10 and the drive 5 are mounted, vertical saws b, 7 mounted on the driven shaft 8. The diameter of the vertical saw 7 is larger than the diameter of the saw b ledge.

Stone cutting machine works as follows

When the machine moves along the bottom 11 at a working speed, a horizontal saw 10 cuts one row of stones in height, and vertical saws b, 7 separate from

an array of two rows of stones 12 and 13, while the second saw 7 of larger diameter produce cuts 9 in the underlying ledge (Fig. 3). The vertical sawblade assembly 5 is equipped with jacks, which allows the disc 7 to be bumped into the underlying ledge.

The proposed stone-cutting machine makes it possible to increase the productivity of works on the extraction of the sturdy stone from the contoured flank trenches.

array per second, even reduce the time spent on auxiliary work on the production of transverse cuts.

Claims (1)

The invention includes a stone-cutting machine, including a chassis, on which a saw carriage is mounted, and a device for producing longitudinal cuts mounted on a saw carriage in the form of a shaft of two vertical saws fixed to the engine, connected to an engine, to separate two rows of stone from an array and a device for the production of horizontal cutting in the form of a horizontal saw shaft fixed on the kinematically connected with the motor for cutting two rows of stones, distinguishing the fact that, for the purpose of increasing the productivity of mining stone sawing of contoured flank trenches and an array by reducing the time spent on auxiliary work on the production of transverse cuts, one of the vertical saws has a larger diameter than the second vertical saw for the production of transverse cuts Fig, 1 Editor T.
