Abstract

The invention relates to the mining industry and can be used to destroy oversize. The goal is to increase the reliability of operation due to the intensification of cooling. The housing 1 is divided into the chamber (K) 3 of the platoon and K 4 expansions with exhaust ports 5 briskly. The piston 9 is placed in the K 6 combustion and divides it into two cavities. One of the cavities communicates with K 4, and the other through a heat exchanger 11 with a storage tank 12. The exhaust ports and a pressure reducing valve 13 communicate K 4 with a storage tank 12. After the combustible mixture in K 6 has ignited, the pressure sharply increases and the piston 9 moves. In this case, the fluid is displaced into the heat exchanger 11 and further into the tank 12. During the return stroke of the piston 9, the fluid returns under the excessive pressure of the exhaust gases and cools the housing 1. 1 sludge.

In this case, the fluid is displaced into heat and returns under overpressure exchanger 11 and further into the tank 12. It draws off exhaust gases and cools the cor- During the return stroke of the piston 9, the fluid starts 1. 1 sludge.

The invention relates to the mining industry and can be used, for example, to destroy oversize.

The purpose of the invention is to increase the reliability of operation due to the intensification of cooling.

Ia drawing shows a diagram of the device.

The device consists of a housing 1 divided by a striker 2 on a platoon chamber 3 and an expansion chamber 4 with exhaust windows 3. A combustion chamber 6, equipped with an inlet 7 and a blocking 8 valves, a piston 9 that separates the combustion chamber into two cavities, one of which is communicated, with the expansion chamber 4, and the other through the cooling jacket 10, the heat exchanger 11 with the storage capacity 12. The expansion chamber 4 through the exhaust ports 5 and the reduction valve 13 is also connected to the storage capacity 12. At the bottom corpus and hosted a working tool 14 "

The device for destroying rocks works as follows;

In the initial position under the action of air pressure in the chamber 3 of the platoon, the firing pin 2 is in the extreme upper position, i.e. pressed to the chamber 6 of the combustion. Working tool 14 is pressed against the object of action. Thereafter, the combustion chamber 6 through the inlet valve 7 is filled with a combustible mixture, which ignites from a spark ignition system (not shown). The pressure in the combustion chamber 6 increases sharply, the piston 9 in the combustion chamber moves and displaces the liquid to the heat exchanger 11, where it is cooled, and then the liquid enters the

storage tank 12. At the same time, the combustion products, from the combustion chamber 6 through the block valve 8 into the expansion chamber 4, act on the firing pin 2 and accelerate it before hitting the working tool 14. At the same time, the exhaust gases from the exhaust ports - the on-valve 13 enters the storage tank 12. The pressure in the combustion chamber 6 drops, and the piston 9 under the influence of the liquid in the storage tank 12 under excess pressure from the exhaust gases occupies the initial initial position s. At this time there is an intensive transfer of excess heat to the liquid cooled in the heat exchanger. The cycle is then repeated as many times as necessary.
