By controlling the engine 2, the dry road marking removal structure 10 can be controlled to clear the road markings.

[0030] The composite dust removal mechanism includes a dust removal box 6 of a closed box structure, such as Figure 5As shown, the inner cavity of the dust removal box 6 is divided into an upper box body and a lower box body by a honeycomb plate 604 with dense through holes. The top of the upper box body is provided with a negative pressure air suction port 608 that penetrates the inner cavity thereof, and a negative pressure fan is provided on the negative pressure air suction port 608. A spray water pipe 609 is fixedly provided in the upper box body, and a plurality of atomizing nozzles are evenly distributed on the spray water pipe 609. The circulating water inlet 605 of the spray water pipe 609 is connected to the circulating water outlet 602 of the lower box body through the water inlet pipe 14 and the water pump 15. A dust screener 603 is provided in the lower box body. The dust screener 603 of the cyclone structure includes an inner cylinder and an outer cover. The lower part of the inner cylinder is a cone structure with a large upper part and a small lower part. The cone structure is airtightly connected to the bottom plate of the lower box body, a discharge port penetrating the bottom plate of the lower box body is provided at the bottom end of the cone structure, and a dust collecting bag 601 is sleeved on the discharge port, a central tube penetrating the top plate of the inner cylinder is provided at the axial position of the inner cylinder, an air inlet 610 penetrating the cylinder wall is also provided at the top of the inner cylinder, the air inlet 610 is connected to one end of the air duct 16, and the other end of the air duct 16 is connected to the working dust chamber, the outer cover of the bottle cap structure is sleeved and installed above the inner cylinder, and an air flow channel is formed between the inner surface of the outer cover and the outer surface of the inner cylinder, circulating dust reduction water is poured into the lower box body, and the liquid level of the circulating dust reduction water is at least greater than the height dimension of the bottom edge of the outer cover.

[0031] When the environmentally friendly road marking removal device is used to remove road markings, the dry road marking removal structure 10 is driven by the engine 2. After the water pump 15 is started, the circulating dust reduction water in the lower box body of the dust removal box 6 can be pumped by the water pump 15 and enter the spray water pipe 609 through the water inlet pipe 14, and then sprayed out by the atomizing nozzle and flowed through the honeycomb plate 604 back to the lower box body of the dust removal box 6, forming a water flow cycle. After the negative pressure fan on the negative pressure suction port 608 of the dust removal box 6 is started, the dust generated during the operation of the dry road marking removal structure 10 is concentrated in the working dust chamber, such as Figure 6 As shown, under the action of negative pressure airflow, the dust airflow can enter the inner cylinder of the dust screener 603 through the air duct 16 and the air inlet 610 in sequence, and the dust airflow swirls in the inner cylinder of the dust screener 603.

Light dust will follow the airflow and leave the dust screener 603 through the central tube and the airflow channel in sequence and enter the lower box body of the dust removal box 6. After the dust airflow passes through the circulating dust reduction water in the lower box body of the dust removal box 6 to absorb part of the dust, it enters the upper box body of the dust removal box 6 through the honeycomb plate 604. The water mist formed by the atomizing nozzle further absorbs the dust particles, and the purified airflow is discharged through the negative pressure air suction port 608. Through the three-level purification of swirl purification, water bath purification and spray purification, it is possible to eliminate working dust and reduce environmental pollution.

[0032] In order to further improve the dust removal and purification effect, as a further improvement scheme of the utility model, Figure 5As shown, a filter assembly 607 is also provided in the upper box body of the dust removal box 6. The filter assembly 607 is located above the spray water pipe 609. The filter mesh aperture can be selected according to the filtering accuracy. The dust airflow after washing can be further filtered and purified by the filter assembly 607, thereby realizing the four-stage purification of swirl purification, water bath purification, spray purification and filtration purification.

[0034] In order to achieve energy conservation and emission reduction, as a further improvement scheme of the utility model, the negative pressure fan on the negative pressure air intake port 608 on the top of the dust removal box 6 is the cooling fan 3 on the engine 2, and the cooling fan 3 is tightly connected to the negative pressure air intake port 608 through the flange sealing cover 4 and the air duct 5. After the engine 2 is started, the cooling fan 3 can be driven to rotate at high speed, and then a negative pressure environment can be formed in the dust removal box 6 through the air duct 5, so that the airflow purified by the dust removal box 6 can be used for heat dissipation of the engine 2, thereby achieving energy conservation and emission reduction.

[0035] For large dust particles that cannot be sucked into the dust removal box 6 by the negative pressure airflow, in order to achieve synchronous cleaning, as a further improvement scheme of the utility model, Figure 1As shown, the frame 1 is also provided with a roller brush 18 and a dust box 12. The roller brush 18 including bristles 19 and a roller brush rotation drive assembly 13 is located behind the marking cleaning mechanism, and the bristles are in contact with the ground. The width dimension of the roller brush 18 along its axial direction can match the width dimension of the operating dust chamber. The roller brush rotation drive assembly 13 can be an independent motor drive structure or a drive structure connected to the engine 2 through a transmission. The dust box 12 is set in front of or behind the roller brush 18 corresponding to the rotation direction of the roller brush 18, and the inlet of the dust box 12 is set corresponding to the roller brush 18. When the road marking is cleared, large dust particles that cannot be sucked into the dust removal box 6 by the negative pressure airflow can be swept into the dust box 12 for storage by the roller brush 18 during the forward movement of the frame 1. In order to facilitate the centralized treatment of large dust particles, the bottom end of the dust bag 601 can be connected to the dust box 12, and the dust in the dust bag 601 can enter the dust box 12 by itself under the action of its own gravity.

[0036] In order to reduce the labor intensity of operators, as a further improvement scheme of the present utility model, a wheel self-propelled driving structure is provided on the front running wheel and / or the rear running wheel of the wheel assembly 8, and the wheel self-propelled driving structure can be an independent motor driving structure or a driving structure connected to the engine 2 through a transmission.

[0037] In order to facilitate the control of the removal depth of the road markings, as a further improvement of the present invention, the front and / or rear running wheels of the wheel assembly 8 are further provided with a wheel lifting drive structure, which can be as follows: Figure 1 The screw lifting structure including the handle 7 shown may also be other lifting drive structures such as a telescopic cylinder structure, which controls the lifting of the wheels to achieve the lifting and lowering of the frame 1, thereby controlling the cleaning depth of the road marking by the dry marking removal structure 10.

[0038] When a wheel self-propelled driving structure is provided on the rear running wheel of the wheel assembly 8, in order to facilitate the environmentally friendly road marking removal device to smoothly climb onto the flatbed transfer transport vehicle through the boarding bridge without the help of external tools or equipment during the transfer, as a further improvement scheme of the utility model, Figure 1 As shown, the front end of the frame 1 is also provided with a transfer boarding wheel 17 which is installed and connected to the frame 1 through a lifting structure. The transfer boarding wheel 17 is located in front of the front running wheel of the wheel assembly 8, and when the transfer boarding wheel 17 is fully lowered, the front running wheel of the wheel assembly 8 can be in a suspended state. At this time, the wheel self-propelled driving structure on the rear running wheel of the wheel assembly 8 can be controlled to drive the environmentally friendly road marking removal device to move forward quickly as a whole. At the same time, when the environmentally friendly road marking removal device climbs onto the boarding bridge by itself, the movement interference between the front end of the frame 1 and the boarding bridge can be avoided.
