Abstract

The invention relates to the mining industry and. b. used in stone cutting machines for the extraction of wall blocks from sawn rock in quarries. The goal is to increase productivity due to the mechanized cutting of blocks adjacent to the safety berm. The stone-cutting machine has a undercarriage 1, the L-shaped frame of which is made with horizontal support 2 with driven rollers (K) 3, 4 and vertical support 5 with driven K 6, 7, Horizontal support 2 is made with an additional section located console in relation to vertical support 5 from the side of the bottom, and K 6, 7 are offset relative to the horizontal support by the amount of the additional area in the side of the bottom. Parallel and perpendicular to the berme 13 vertical cuts are cut with a stone-cutting machine. Then the rail 14 is laid on the roof of the ledge and on the berm, and the rail 15 is laid on the bottom of the ledge. The stone cutting machine, moving along the rails, cuts the blocks along the entire bottom, and the milling cutter 11 of the horizontal cutting mechanism 9 cuts the blocks, including the block in the berm zone. 3 il. with (L

The exit trench was bathed with an on-access stone-cutting machine, for example, the KNKM-1 (2), parallel 16 and perpendicular 17 berme 13 vertical cuts were cut. Then the rail 14 is placed on the roof of the ledge and on the berm, and on the bottom of the ledge, butt to the base of the berm, rail 15. Moving along the rails, the stone-cutting machine cuts the blocks along the entire length of the bottom, and at the end of it in zone B

 The invention relates to the mining industry and can be used in stone cutting machines for the extraction of wall blocks from sawn rock in quarries.

The purpose of the invention is to increase productivity due to mechanized extraction of blocks adjacent to the safety berm.

Claims (1)

Invention Formula The sawing machine contains a saw carriage with rollers and horizontal and vertical cutting mechanisms, a running carriage with an L-shaped frame, made with horizontal and vertical cutter 12 to the berme when cutting the last block. The machine is moved along rails 14 and 15. ; The machine works as follows, i In zone B, located at the end of the abot and equal in width to the distance between the axes of the cutters, plus the radius of the horizontal cutter, i.e., in the zone where before using the proposed machine, The cutout of blocks adjacent to the safety berm of the bottom, the horizontal support of the L-shaped frame of the stone-cutting machine is made with an additional section located cantilever relative to the vertical support on the side of the bottom, and the rollers of the saw carriage are offset from the horizontal support by an additional portion toward the side. The exit trench was bathed with an on-access stone-cutting machine, for example, the KNKM-1 (2), parallel 16 and perpendicular 17 berme 13 vertical cuts were cut. Then the rail 14 is placed on the roof of the ledge and on the berm, and on the bottom of the ledge, butt to the base of the berm, rail 15. Moving along the rails, the stone-cutting machine cuts the blocks along the entire length of the bottom, and at the end of it in zone B „ due to the fact that the vertical support 5 is shortened and does not prevent the rolling and supports, characterized in that, for the purpose into the lead-in trench, and the cycle repeats, and the cut blocks are removed to the warehouse. Invention Formula A stone-cutting machine containing a saw carriage with rollers and horizontal and vertical cutting mechanisms, a chassis carriage with an L-shaped frame, made with horizontal and vertical 0 The cutout of blocks adjacent to the safety berm of the bottom, the horizontal support of the L-shaped frame of the stone-cutting machine is made with an additional section located cantilever relative to the vertical support on the side of the bottom, and the rollers of the saw carriage are offset from the horizontal support by an additional portion toward the side.
