The invention relates to the field of mining and construction, in particular for machines for the destruction of frozen and durable soil gasoinline effect.

Known technical solution consists in the fact that the device for the destruction of a ground pulse of high pressure gas contains bury in the ground the tip and connected therewith a tubular body with a tank of compressed gas, through which the valves are communicated with the supply line of gas and exhaust holes in the body, located near the tip (ed. St. N 569687, CL E 02 F 5/18, 1976).

In the known device the exhaust valve is adjusted to a certain pressure of the compressed gas and there is no possibility to automatically regulate the pressure of gas in the tank, depending on the strength of erodible soil.

It is also known device (ed. St. USSR N 621839, CL E 02 F 5/30, E 21 37/14, kotorogo is capacity, filled with a compressed gas. In the lower part of the working body in a tubular housing with holes for exhaust of compressed gas from the tank. In the tank is a spring-loaded piston is connected by a thrust with the overlapping of the exhaust valve hole and the separating space of the vessel into two chambers. One camera through a controlled valve is in communication with the gas inlet line, the other with exhaust holes. The camera can be periodically connected via through holes in the piston, which has a spring-loaded valves.

The disadvantage of this device is to limit the pressure values, because the stiffness of the spring valve significantly reduces the range of the required pressure for the destruction of the soil, making it economical enough. Another disadvantage is the lack of adaptability to soil conditions.

It is also known a device for loosening soil (ed. St. USSR N 1078003, CL E 02 F 5/30, 1984).

The device includes a screw tip connected to the tubular body, a container for compressed gas, made for the housing of the working body, through which the exhaust valve is in communication with the supply line of gas and with the normally open valve, shut-off element which is located on the side of the vessel.

The downside of it is high intensity, so as normally open valve mounted at the outlet from the tank, has a significant resistance to the outflow of gas, and due to their large inertia due to the presence of springs, the resistance which must be overcome compressed gas at the end, he covers only the remnants of the compressed gas, after actuating the sharp increase of the expiration of the compressed gas, thereby missing the bulk of it in the atmosphere and blocking only the compressed gas remaining in the tank, and the gas filling of the tubular body, is lost. In addition, the known device does not allow to regulate the pressure of gas in the tank in accordance with the specific ground conditions, that is, to set the optimum pressure of the compressed gas depending on the physico-mechanical properties of soil.

Closest to the claimed device is a device for loosening soil (ed. St. N 2004710, CL E 02 F 5/32, 1993).

The device includes a hydraulic drive, the compressor, the working body in the form of a tubular casing with a screw tip having near the last exhaust mu includes basic and additional working camera, gazoprovoda piping and valve mechanism, including a working valve overlap of exhaust apertures, the camera control work valve connected through gazoprovoda tube passing through the working valve, a source of compressed gas or atmosphere.

The disadvantage of this device, despite the detailed development of each element is the excessive workload of the structure and its large dimensions, since all work items are inside the working body, and lack of adaptation to soil conditions, since the destruction of the soil is carried out by a pulse of compressed gas to a predetermined pressure.

The objective of the proposed solutions is to eliminate these disadvantages.

The invention consists in that in gatenoise the Ripper containing hydraulic, compressor and the working body in the form of a tubular casing with a screw tip having near the last exhaust holes placed inside the housing, coaxial him, tubular hollow cylinder, gas distribution system, including primary and secondary working chamber, gazoprovoda troopa work valve, connected through gazoprovoda tube passing through the working valve with a source of compressed gas or atmosphere, according to the invention, the tubular hollow cylinder configured to move the follower type, the inner cavity of which simultaneously is the main working chamber and on the top, opposite the screw tip, the end of the tubular hollow cylinder made rigidly connected with the piston, and valve mechanism includes camera control plunger, which placed the working end of the piston, and the secondary working chamber, which functions as a storage of compressed gas, outside of the working body and connected with the main working chamber through radial channels, made in the tubular body, and longitudinal slots made in the upper part of the pusher, the length of which is equal to the length of the stroke of the follower on the outer surface of which is directed toward the inner side of the tubular housing, the o ring with the possibility of overlap when moving the pusher exhaust holes radial channels in the tubular casing, primary and secondary camera connected to the camera control valve through the work the ring over in turn by a source of compressed gas or atmosphere.

In addition, this object is achieved due to the fact that latinpussy Ripper can be supplemented reducing valve, consisting of two membranes connected to the valve to supply compressed air from a compressor.

The claimed technical solution is illustrated by the drawing, which shows a General view of the inventive latinolingo Ripper.

Ripper contains a working body in the form of a tubular body 1 with a screw tip 2 and the exhaust holes 3, the overlapped work valve 4 located in close proximity to exhaust vents. Inside the tubular body 1 coaxially placed him tubular hollow cylinder 5, is arranged to move the follower type, the inner cavity of which simultaneously is the main working chamber 6, and the upper end of the small tubular cylinder 5 is made rigidly connected with the piston 7. The gas distribution system includes a main working chamber 6 and the additional working chamber 8, which serves as a storage of compressed gas and outside of the working body and connected with the main working chamber 6 through the radial channels 9, made in the tubular body 1, and the longitudinal a surface which has a sealing ring 11. Latinpussy Ripper also contains the hydraulic actuator 12, a compressor 13, the gas distribution system in addition to the primary and secondary 8 working chambers includes gazoprovoda pipes 14, the valve mechanism, which includes the camera control 15 working valve 4 connected through gazoprovoda tube 16 passing through the working valve 4, with a source of compressed gas or atmosphere, the control chamber 17 of the plunger 5, which placed the working end of the piston 7. The main 6 and an additional 8 working camera connected to the camera control 15 working valve through the annular gap 18 formed between gazoprovoda tube 16 and the working valve 4. The control chamber 17 of the plunger 5 is connected in turn to a source of compressed gas or atmosphere. Gazoprovoda tube 16 passes through the piston 7 by a sealing sleeve (not shown). Additional working camera drive 8 is rigidly mounted on the tubular body 1 of the Ripper through the gas distribution ring 19.

The camera control 15 working valve 4 through gazoprovoda tube 16 and the gas distribution ring 20 three-way valve 21 is connected with a pressure reducing diaphragm valve pressure reducing diaphragm valve 22. The hollow tubular plunger 5 with the outer side facing the inner side of the housing of the working body 1 has two sealing rings 24 and 11, the size of which is commensurate with the size of the stroke of the pusher (equal to the height of the camera control valve). Valve pressure reducing valve mechanism includes a hydraulic actuator 12 in the form of the motor junction box 25, pump 26, a system of distribution pipes 27. Himself a pressure reducing diaphragm valve 22 consists of two membranes 28 and 29 are rigidly connected with the valve stem 30 overlying the access of compressed gas from the compressor 13. Each of the membranes in contact respectively with pneumatic 31 and 32 hydraulic chambers a pressure reducing valve.

The loosening of the frozen soil of the proposed CSD is as follows. To tubular body 1 of the hydraulic motor 12 is transmitted torque. Under the action of this moment, the screw tip 2 is wrapped in an array, immersing in frozen soil working body with exhaust holes 3 to a predetermined depth. Torque on the rod depends on the actual soil strength and, consequently, the pressure in the hydraulic actuator of the working body rises to a certain of westok, opens the valve 30. Gas from the compressor 13 into the chamber 31, then through the valve 21, the gas distribution ring 20 and Gazoprovod tube 16 enters the control chamber 15 working valve 4. The gas exerts on the valve surface 4, pressing it up to the ring of the pusher 5. The valve closes the exhaust hole 3, and the plunger 5 is lifted up, revealing the entrance of compressed gas through the main working chamber 6 of the slot in the plunger 10, the radial channels 9 and the gas distribution ring 19, the drive 8. Through the annular gap 18 between the gas-feeding tube 16 and the channel walls in the operating valve 4 gas gradually fills the main working chamber 6 and the additional working chamber of the accumulator 8 to the pressure required to fracture the soil adequate strength. The control chamber 17 of the piston 7 of the plunger 5 through the pipeline 14 and the gas distribution ring 23, is filled with gas to the same pressure. Upon reaching the working body with the exhaust holes 3 required depth, actuates solenoid pneumatic three way valve 21, which cuts the gas supply from the compressor 13 to the working body and connects the control chamber 15 working valve 4 with the atmosphere (Ref. 2). Due to the drop dichotic pulsed gas flow in the soil and its destruction. After the destruction of the soil gas pulse, the pressure in the chamber 6 and the drive 8 drops sharply, and the gas pressure in the control chamber 17 by the piston of the plunger is transmitted to the plunger 5, the latter under the action of this force moves down and its sealing rings 11 and 24 overlaps the exhaust hole 3 and hole through which an end of the gas in the accumulator 8 and, consequently, stops the outflow of gas from the chambers 6 and 8. The workflow is pumped.

The use of the proposed Ripper allows you to reduce the energy intensity of the process of destruction of the soil, because, first, into the working chamber and a drive pressure reducing diaphragm valve pumped the gas, the pressure which is necessary for the destruction of this soil strength; secondly, when a sharp drop in gas pressure, resulting in the destruction of the soil, the pusher their sealing rings overlaps the gas at the outlet of the working chamber and the drive, eliminating wasteful leakage of gas into the atmosphere.
