Referring to the operation of the road marking removal device configured as follows.

Here, the mini grains are explained as steel balls.

First, when the pressurized hydraulic oil is supplied from the hydraulic supply unit (not shown), the rod 570 of the hydraulic cylinder 560 protrudes and the housing 100 descends and lands on the road markings of the road. The second space combustion means 210 of the housing landed on the road marking is ignited by the gas injected into the space portion through the nozzle from the gas tank and the road surface indication of the road accommodated in the second space portion 210. Heat is applied to burn off the paint on the road surface.

At this time, the harmful gas generated in the process of burning the road marking is sucked into the exhaust hole 223 by the suction force of the suction fan 260, and passes through the purifying means 240, and only the harmful gas is discharged to the outside.

As such, when the combustion process of the second space part 200 is completed, the pinion 520 meshes with the rack 520 to move horizontally by driving the motor 530 of the transfer means 500 so that the second space part 200 of the housing is moved. The first space portion 300 is positioned at the position of the first space portion, and the injection means of the first space portion sprays high-pressure steel balls on the road surface display that is primarily combusted so that the road surface display is destroyed from the road surface.

After the spraying process in which the road surface display is destroyed by the spraying means 310 of the first space part 300, the pinion 520 is engaged with the rack 510 by the driving of the motor 530 to move horizontally, and the housing ( The third space portion 400 is located at the position of the first space portion 300 of 100, and vacuum suctions waste such as high-pressure sprayed mini grains, paint residues, and dust on the bottom surface of the waste space through the suction pipe 430. Automatic collection to the collection box (450).

The waste sucked into the waste collection through the suction pipe 430 falls into the waste accommodating part 452 and the steel ball is attached to the electromagnet 474 of the separating means and separated from the waste. When the separating means 470 having the steel balls is attached to the pinion 476 of the driving shaft by the rotation of the driving motor 477, the rack 475 moves and moves to the upper part of the steel ball receiving portion 453. The power is cut off by the electromagnet 474 by the 455, and the steel balls fall into the steel ball receiving portion 453, and flow into the storage tank 340 on the inclined surface of the separator 451 to be reused.

When the road marking is removed as described above, the pinion 520 is positioned at the end of the rack 510 so that the housing 100 is automatically lifted by the position sensor 590, and the pinion is rotated by the reverse rotation of the motor. 520 is moved to the tip of the rack 510, and the vehicle moves to burn the road markings by repetitive work in the next position.

Although the embodiments of the present invention have been described in detail as described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiments of the present invention.

As can be seen from the above description, the present invention is mounted on a vehicle and moved together with the vehicle, and can improve work efficiency by quickly and efficiently removing road markings by a stepwise process of combustion means, injection means, and suction means. In addition, the harmful gas generated during combustion is not discharged to the outside, but is collected by the filter which removes harmful gas. There is an effect that can resolve the inconvenience of citizens.

In addition, since the ignition of the gas is not exposed to the outside, there is little heat loss, which not only saves energy, but also prevents the safety accidents of the worker. The cost can be greatly reduced.
