Изобретение относитс к горной промышленности .The invention relates to the mining industry.

Известно устройство дл разрушени горных пород, включаюш,ее корпус, поршень-боек , цилиндр с продувочными окнами , компрессорную полость, систему впрыска топлива и рабочий инструмент 1.A device for the destruction of rocks is known, including its body, a piston head, a cylinder with purge ports, a compressor cavity, a fuel injection system and a working tool 1.

Его недостатком вл етс низкий КПД.Its disadvantage is low efficiency.

Наиболее близким к изобретению по технической суш,ности и достигаемому результату вл етс устройство дл разрушени горных пород, включаюшее корпус с продувочными каналами, поршень-боек со штоком , компрессорные и аккумулирующие камеры , свободнопоршневые двигатели, систему подачи топлива и рабочий инструмент 2.The closest to the invention in terms of technical dryness and the achieved result is a device for rock destruction, including a housing with blow channels, a firing piston with a rod, compressor and storage chambers, free piston engines, a fuel supply system and a working tool 2.

Его недостатком вл етс низкий КПД и мала энерги единичного удара.Its disadvantage is low efficiency and low single impact energy.

Цель изобретени - повышение КПД и энергии единичного удара.The purpose of the invention is to increase the efficiency and energy of a single blow.

Дл достижени указанной цели поршни свободнопоршневых двигателей соединены т гами со штоком, который установлен в поршне-бойке с возможностью взаимодействи с ним через аккумулирующие камеры.To achieve this goal, the pistons of free piston engines are connected by rods with a rod, which is installed in a piston-hammer with the possibility of interaction with it through accumulating chambers.

Между корпусом и торцами поршн -бойка могут быть расположены компрессорные камеры, которые каналами сообщены с цилиндрами свободнопоршневых двигателей.Compressor chambers can be located between the casing and the ends of the piston-clutch, which are connected by channels with the cylinders of free piston engines.

Цилиндры свободнопоршневых двигателей могут быть размещены симметрично относительно общего поршн каждой пары двигателей.Cylinders of free piston engines can be placed symmetrically relative to the common piston of each pair of engines.

На чертеже изображено предложенное устройство.The drawing shows the proposed device.

Устройство состоит из корпуса 1 с продувочными каналами 2 и компрессорными камерами 3 и 4, внутри которого расположен поршень-боек 5 с аккумулирующими камерами 6 и 7 и штоком 8, соединенным т гами 9 с поршн ми 10 свободнопоршневых двигателей 11, имеющих симметрично расположенные цилиндры 12 с системой впрыска топлива 13 и выхлопными окнами 14.The device consists of a housing 1 with purge channels 2 and compressor chambers 3 and 4, inside of which there is a firing piston 5 with accumulating chambers 6 and 7 and a rod 8 connected by tubes 9 with 10 pistons of free-piston engines 11 having symmetrically located cylinders 12 with fuel injection system 13 and exhaust windows 14.

Рабочий инструмент 15 расположен в буксе 16. Дл запуска устройства в работу имеетс стопорный механизм 17 и пусковой канал 18 с обратным клапаном.The working tool 15 is located in the box 16. A locking mechanism 17 and a starting channel 18 with a check valve are provided for starting the device.

Устройство работает следующим образом .The device works as follows.

Поршень 10 одного из двигателей перекрывает выхлопные окна 14 и в этом положении стопоритс механизмом 17. После этого в цилиндр 12 через канал 18 подаетс сжатый воздух до срабатывани стопорного механизма 17. При этом поршень 10 движетс влево вместе с т гой 9 и штоком 8.The piston 10 of one of the engines blocks the exhaust ports 14 and is locked in this position by the mechanism 17. Thereafter, compressed air is supplied to the cylinder 12 through the channel 18 until the locking mechanism 17 is activated. At the same time, the piston 10 moves to the left along with the thrust 9 and the rod 8.

Claims

After the exhaust ports of the cylinder 12 are blocked, the piston 10 compresses the air, turns on the fuel injection system 13 and after a flash of fuel moves in the opposite direction. During this period, the rod 8 compresses the air in chamber 6 and, together with the piston brisk 5, moves to the left. At the same time, the air in chamber 3 is compressed and passes through channel 2 to blow into cylinder 12. When the piston 10 reaches the dead point, the piston head 5 moves to the left by inertia under the action of air pressure in chamber 6 until it hits the tool 15. After that, the piston hammer 5 moves to the right. At the same time, the air in chamber 4 is compressed and through channel 2 it blows the cylinder 12. After the air in cylinder 12 is compressed, the fuel injection system is turned on again and the cycle repeats. The use of the device allows to increase the efficiency and energy of a single blow depending on the number of free piston engines. Claim 1. Device for destroying rocks, including a housing with purge channels, a piston rod with a rod, compressor and storage chambers, free piston engines, a fuel supply system and a working tool, characterized in that in order to increase the efficiency and energy of a single blow , pistons of free piston engines are connected by rods with a rod, which is installed in a piston striker with the possibility of interaction with it through accumulating chambers. 2. The device according to claim 1, characterized in that between the housing and the ends of the piston-compressor there are compressor chambers that are connected by channels with the cylinders of the free-piston engines. 3. The device according to claim 1, characterized in that the cylinders of free piston engines are arranged symmetrically with respect to the common piston of each pair of engines.
