Description

The invention relates to devices for the destruction of the soil by detonating the impact of combustion products on it and can be used to equip earth-moving machinery.

A device is known for destroying soil by exposing it to combustion products, including a combustion chamber and a power supply unit connected to it. To ignite the fuel mixture, there is a ignition mechanism operatively connected to a synchronizer that regulates the moment of ignition depending on the rotation of the shutter blocking the outlet of the combustion chamber tU. The closest technical solution to the present invention is a device for destroying the soil by detonating impact of combustion products on it. containing a combustion chamber, closed at the outlet of the Slonka, which is attached to the housing of the hinge chamber and connected via a cable rugim lever cooperating with the movable cracker, during its translational movement opening and closing the shutter t lKonstruktsii known devices requires synchronizer regulating the timing of ignition of the fuel mixture, wherein

The operation should be used to expel unburned mixtures from the combustion chamber in the event of an unexpected opening of the valve. The applied synchronizers of the mechanical action are unreliable in operation, since their work is not associated with the combustion process.

The purpose of the invention is to increase the reliability of the device.

This is achieved as a result of the fact that a ram cylinder connected by a piston cavity with the space of the combustion chamber and connected by a piston to a cracker is installed on the body of the combustion chamber.

FIG. 1 shows the proposed device, in the position when the rotary valve is closed, a longitudinal section; on fng. 2 - the same when the butterfly valve is open.

A device for destroying soil by detonating products burns. It has a combustion chamber i with a rotary valve 2 at the exit, which is pivotally fixed in its casing 3 by means of a lever 4, which sits on axis 5. With lever 4, rod 6 is pivotally connected, and elastic lever 7, ii: arbor fixed fia to support 8 .

On the torpus 3 of the combustion chamber 1, a power cylinder 9 is mounted, communicated by its piston cavity 10 through channel I with the appearance of the combustion chamber 1. In cylinder 9 there is a piston 12, the rod 13 of which is connected to the cracker 14. moving along the guides 15 and interacting, nm with the elastic lever 7. At the end of the stroke of the rotary valve 2, a damper 16 is installed. The device operates as follows. When the combustion chamber i is filled with the fuel mixture, it enters through the channel 11 into the cavity 10 of the power cylinder 9. The pressure in the cavity 10 rises and the piston 12 together with the rod 13 and the cracker 14 moves, compressing the air in the cavity 17 of the power cylinder 9 until the articulated joint touches 6 and the elastic arm 7 with the bevel 18 rusks 14 (see Fig. 1). Then penetration of the fuel mixture in the combustion chamber 1 is carried out. When the front of the channel is reached, the pressure in the cavity 10 of the cylinder of the cylinder 9 sharply increases and the piston 12; under the influence of daaiiin products of combustion peMeuiaercH, compressing the air in the cavity 17. Bevel. 18 suhar 12 interacts with the hinged connection of the yi and the elastic arm 7. As a result of the joint action of the elastic arm 7 and the pressure of its products Haf, the butterfly valve 2, the ton ha 6 and the elastic lever 7 abruptly fold, and the butterfly valve 2 opens. In the stroke of its stroke, the butterfly valve 2 interacts with the damper 16 and is thus prevented from being destroyed. Combustion products expire from combustion chamber 1 and act on the ground, destroying it. After that, the pressure in the combustion chamber 1 and the cavity 10 of the power cylinder 9 drops, and the piston 12 under the action of the pressure of compressed air in the cavity 17 of the power cylinder 9 mixes, displaces the combustion products from the cavity 10 through kak 11 into the combustion chamber. in interaction with the elastic lever 7 and returns the hinge connection of the pin 6 and the elastic lever 7 to the original position: (see Fig. 2). In this case, the rotary shutter 2 closes the chamber I S1X) wounds and the device is ready for a new cycle of operation. The present invention will improve the reliability of the device, since the energy of the combustion products is used to rotate the rotary valve. An unproductive outflow of the combustible mixture is completely used (because the combustion chamber can only be opened after the fuel mixture has ignited. The proposed design of the device can also be widely used in pneumatic installations, which are based on high-speed outflow of the gaseous medium. Formula of the invention. Ground destruction device by detonating the combustion products on it,; containing a combustion chamber that is closed at the outlet by a damper, which is fixed on the Kopity chamber They are hinged and connected through a puller with an elastic lever, which is connected with a movable cracker, with its forward movement opening and closing the valve, characterized by the fact that, with the aim of increasing the reliability of its operation, a power cylinder is mounted on the body of the Combustion Chamber and is connected to a piston housing. space of the combustion chamber and connected by its piston to the cracker.
