In FIG. 1 shows a general diagram of a device.

In FIG. 2 is a block diagram.

In Fig. 3 - source of compressed gas and electricity.

In FIG. 4 - feeder-dispenser.

The coating device consists of a control panel 1, a source of compressed gas and electricity 2, a movable chamber 3, an ultrasonic generator 4. The movable chamber is divided by a partition 5 into lower and upper parts. The lower part is equipped with an accelerating nozzle 6 for surface treatment and a nozzle 7 for coating, an equalizer 8, a receiving tank 9 for excess coating, a base 10 with needles 11. In the upper part of the chamber 3 there is a metering feeder 12, a fan 13 for cooling the piezoelectric elements, a drive 14 for wheels 15 and another. An ultrasound source 16 with piezoelectric elements 17 and a reflective plate 18 is also placed in the chamber 3.

The feeder-feeder 12 consists of a housing 19, a nozzle 20 with a swirl 21, a mixing chamber 22, a fitting 23 for receiving hot gases from a source 2 receiver, a hopper 24 with a coating 25, a drum 26 with teeth 27, a coating feed regulator 28 with an eccentric drive 29, a bump stop 30 of elastic material to prevent the coating 28 from falling into the gap between the housing 19 and the drum 26, gas channels 31 and 32, fitting 33 to exit the mixture of coating and gas. The pipeline 34 is equipped with an ozone insert 35, which is a tube, inside of which around the perimeter is carbon felt and a shielded electrode.

The source of compressed air and electricity 2 contains two twin opposed pistons. Each twin piston consists of a piston 36 of the combustion chamber and a piston 37 of the compressor. These pistons with a cylinder 38 form a combustion chamber 39, equipped with a nozzle 40, inlet 41 and outlet 42 windows. Windows 42 are connected through a valve 43 to a receiver 44. Each piston 36 of the combustion chamber 39 is provided with solenoids 45 for generating electricity. Source 2 is equipped with buffer cavities 46, a receiver 47 for compressed air with inlet valves 48, a cavity 49, a compressor with inlet valves 50, a pipe 51 for the exit of compressed air and pipes 52 for hot gases. The pipelines after the nozzles 51 and 52 are connected through an adjustable fan 53. The pipe after the ozone insert has an outlet 54 for connecting a hose to it with a nozzle for manual preparation of the surface for coating.

The conical part of the nozzles 6, 7, the base 10 with needles 11, the lower part of the ultrasound source are removable and interchangeable (not shown) to provide a wider or narrower grip of the treated surface. The device is equipped with a lever 55 with a control panel 1 and a handle 56 located on it.

The device operates as follows.

The truck with the device using the lever 55 and the handle 56 is sent, for example, when repairing cracks in the road surface along the crack.

Further, the movement along the cracks manually visually or using a special device (not shown). From the control panel 1, a source of compressed gas and electric energy is launched, the speed of the trolley is set, for which the drive 14 is turned on, which moves the trolley, the base 10 with needles 11, the drum 26, the eccentric drive 29. The drive 29 slows down when the base 10 is lowered and raised. trolley and drum movement 26.

To start the source of compressed gas and electricity, 2 pistons with a starter (not shown) or by supplying voltage to the solenoids are moved to extreme positions. While the air in the buffer cavities 46 is compressed, through the valves 50 into the cavity 49 of the compressor, atmospheric air is sucked. Through the intake ports 41, air enters the combustion chamber from the receiver 47. Compressed air in the buffer cavities 46 of the pistons converge. Windows 41 and 42 are closed. The air in the combustion chamber 39 is compressed. Upon reaching a certain degree of compression, fuel is injected into the combustion chamber 39 through the nozzle 40. The air-fuel mixture ignites and the work process begins. The pistons 36 and 37 diverge, the windows 42 open, and the combustion products rush into the receiver 44 through the valve 43. Then the windows 41 open and the air from the receiver 47 blows and fills the combustion chamber 39. Then the process is repeated. Compressed air in the buffer cavities 46 of the pistons converge.

When the pistons 36 move in the solenoids 45, electricity is generated. Through the nozzle 51, the compressed heated air through the ozone insert 35 enters the accelerating nozzle 6 and blows dust, small particles out of the crack, while simultaneously warming the surface to be treated. Ozone in the composition of the air helps to remove oils, acids and other from the surface, improves adhesion with the applied coating. Through the pipe 52, hot gas enters the nozzle 20 of the metering feeder 12 through its pipe 23, the swirler 21 and is directed at an angle to the drum 26 with teeth 27 and then into the mixing chamber 22, into which simultaneously from the hopper 24 through the coating regulator 28 with an eccentric drive 29, coating 28 is supplied with the help of teeth 27. In mixing chamber 22, coating 28 is mixed with hot gas and through the nozzle 33 enters the accelerating nozzle 7 and then to the surface, penetrating into voids, capillaries, channels. Gas from the mixing chamber 22 through the channel 32 enters the surface above the coating 28 of the hopper 24 and equalizes the pressure there, facilitating the penetration of the coating 28 into the mixing chamber 22. Through the channel 31, the gas enters the gap between the housing 19 and the drum 26 and cleans it of particles of the coating 28 .

The equalizer 8 levels the applied coating 28 on the surface and dumps the excess into the container 9. The latter is easily installed and removed, and the assembled coating can be reused.

For better penetration into the capillaries, the coating channels 28, the device is equipped with an ultrasound emitter 16, which is affected by an ultrasound generator through a piezoelectric element 17. Cooling the piezoelectric elements 17 with a fan 13.

The combination of a high speed of the outflow of the jet from the nozzles processing and heating the surface with an air-gas mixture with ozone, the formation of additional channels in the surface, the effect of ultrasonic vibrations on the applied coating ensure high-quality repair of the road surface, repair of cracks and potholes without cutting them at any crack width.
