Description

Изобретение относитс к добыче природного стенового камн , например известн ка, в частности к устройствам дл тыльного отделени штучного камн от массива.The invention relates to the extraction of natural wall stone, for example limestone, in particular to devices for the rear separation of piece stone from an array.

i Известно устройство дл добычи мерных блоков естественного камн в виде гидроклиньев с приводом, которые вставл ютс в предварительно пробуренные по линии раскола шпуры с прорезанными между шпурами щел ми IJ.i A device is known for the extraction of natural stone blocks in the form of hydro-driven drives, which are inserted into pre-drilled holes along the split line with gaps IJ cut between the holes.

Недостатком этого устройства вл етс низка производительность и качество отделени штучных камней от массива.A disadvantage of this device is the low productivity and quality of separation of the block stones from the array.

Наиболее близким к предлагаемому по/ технической сущности и достигаемомурезультату вл етс устройство дл отделени штучного камн от массива, включающее штыбоприемник, механизм откола камн с распорными щеками, привод механизма откола и инструмент тыльного реза, выполненный в виде фрезы. Штыбоприемник, механизм откола и фреза ввод тс в горизонтальный пропил в массиве породы и после образовани тыльного пропила производитс откол камн и подача его на штыбо приемник С 23.The closest to the proposed by the technical essence and the achieved result is a device for separating a piece stone from an array, including a bayonet receiver, a mechanism for splitting stones with spacer cheeks, a drive for a mechanism for splitting and a tool for rear cutting, made in the form of a milling cutter. A pin holder, a spall mechanism and a milling cutter are inserted into a horizontal kerf in the rock mass and after the formation of a back kerf, a stone is broken off and fed to the bar pin C 23.

Недостатком известного устройства вл етс сложность конструкции инструмента тыльного реза.A disadvantage of the known device is the complexity of the design of the rear-cut tool.

Цель изобретени - упрощение конструкции устройства.The purpose of the invention is to simplify the design of the device.

Указанна цель достигаетс тем, что в известном устройстве, вк.гаочаю1дем штыбоприемник, механизм откола This goal is achieved by the fact that in the known device, in the coaxial receiver plug-in mechanism, the spall mechanism

10 камн с распорными щеками, привод механизма откола и инструмент тыльного реза, последний выполнен в виде твердосплавного клинового ножа, установленного на конце распорной щеки 10 stones with spacer cheeks, a drive of the spall mechanism and a tool for rear cutting, the latter made in the form of a hard-alloy wedge knife mounted on the end of the spacer cheek

Claims

A device for separating a piece stone from an array contains a splinter 1, a spacer cheek 2, sliding across the back surface of the 3 pushers, and a shock-dynamic drive 4, for example in the form of a double-acting hydraulic cylinder, into the supply line of which a device is inserted that excites shock waves . A device for separating a piece stone from an array is made together with a bayonet receiver 5 on chassis 6 (see figure 2). A carbide wedge knife 7 is made on the outer surface of the pusher. A device for separating a piece stone from an array works as follows. The device is inserted into the horizontal cut 8 up to the stop (shown in Fig. 1 in solid lines). After that, the drive 3 and the cheek 2 are turned on, moving along the beveled rear surface of the pusher, moves it down. At the same time, the pusher 1 with the knife 7 begins to cut the stone to be separated 9, forming a voltage hub slot. With further movement of the cheek 2, the pusher 1 with its supporting surface 10, leaning against the separable stone 9, makes it cut from the array. To mechanize the removal of the stone separated from the massif, the device is mounted on the forks of the loader. This allows mechanized removal of the stone at the same time as the stone-cutting machine operates. The invention makes it possible to simplify the design of the device, increase the labor productivity, reduce the energy consumption of stone separation, reduce the wear of carbide tools and improve the working conditions in the extraction of natural piece stone. Apparatus of the invention for separating a piece stone from an array, including a pin holder, a mechanism for breaking stone with spacer cheeks, a drive for a mechanism for spalling and a back cut tool, characterized in that, in order to simplify the design of the device, the tool for the back cut is made in the form of a hard-alloy wedge knife at the end of the expansion cheek from the side of the stone to be cut.
