(54) DEVICE TO DESTROY MOUNTAIN BREEDS

one

The invention relates to the mining industry and can be used in devices for breaking rock pieces.

A device for the destruction of rocks, including a housing, a piston head, a piston rod, a piston casing, a purge tank and a working tool 1, is known.

A disadvantage of the known device is the reduction of the impact energy due to the compression of the air in the side of the collar.

Closest to the invention, a device for destroying rocks, comprising a housing, a combustion chamber, an expansion chamber, a piston head, a receiver 15 connected by channels with an expansion chamber and a pit cavity, a drummer, and a working tool 2.

A disadvantage of this device is the increased consumption of compressed air due to Q due to bleeding it from the tamping cavity through a pressure reducing valve.

The purpose of the invention is to increase the efficiency of the device by reducing the flow of compressed air.

This goal is achieved by the fact that the channels associated with the receiver and, accordingly, with the expansion chamber and the collar cavity, are located at a distance from each other along the generator of the body equal to the length of the piston-forming piston, while the channel informing the expansion chamber with the receiver equipped with a check valve.

The drawing shows a device for the destruction of rocks.

The device for destroying rocks includes a housing 1 in which a combustion chamber 2 is located, an expansion chamber 3 communicated through an opening 4, blocked by a valve 5 under the action of compressed air supplied through pipeline 6. The combustion chamber is equipped with a spark plug 7, an inlet valve 8 and an exhaust valve 9. Inside the housing there is a piston-gun 10, a drummer 11, between which there is a sub-collar 12, equipped with a pressure-reducing valve 13 connecting it with the atmosphere, and a crane 14 connecting it with a source of compressed air spirit (not shown). The expansion chamber through channel 15 and check valve 16 communicates with receiver 17. which is connected by channel 18 to the nolbokovy nolostyo 12. And the working tool 19 is mounted to the neater of the impactor II. Kaia: n 1 15 and 18 are located from each other at a distance of the housing one; equal to the length of 11

The device works with;

Work tool 19 is mounted on a ra; funded object. A d.1 of the nervous node of the norshnboy 10 to the extreme isep.xHee operating position or source of air through valve 14 to the single sliding chamber 12 compressed air is attached, with aperture 4 and a vial 9 open. Ioschea’s Iodus of the I & N pusher) to the uppermost slave (; the position of the valve 14 overlaps.) Then, in the combustion chamber 2 through the clans ’assembly 8, an air-supply mixture is supplied. In this case, the combustion chamber 2 is sealed. the 1414 air mixture to 1) the working pressure, the mixture is stopped. Then a signal is sent to the spark plug 7, and the combustible mixture is ignited. The pressure in the combustion chamber 2 increases dramatically, the valve 5 opens the opening 4 and the products C14) wounds flow into the expansion chamber 3. Under the influence of the pressure of the combustion products, the firing pin 10 accelerates and shrinks gases in the butt-block cavity 12, the excess of which is released into the atmosphere through The pressure reducing valve 13 is regulated by pressure} 1, it is necessary for lifting the pornographic shock 10. In the process of moving the horizontal shock 10 down, the latter closes the channel 18, opens the channel 15 and strikes the slave 11 Why tool 19, directly acting on the destructible object. At the moment of opening of the channel 15, the combustion products rush through the non-return valve 16 to the receiver 17 from the expansion chamber 3.

When the piston-rifle 10 is fired by the energy of the rebound and compressed 1 hour. -Boy I) in the highest working position.
