[0015] A cleaning frame is provided with a rotating roller, on which a rolling brush is provided, and the rolling brush corresponds to the position of the bucket;

[0016] The motor is arranged on the cleaning frame and connected with the rotating roller to provide power to the rotating roller.

[0017] Furthermore, a roller is arranged below the dust collecting bin.

[0018] Furthermore, the telescopic assembly adopts a hydraulic cylinder.

[0019] The working method of the utility model is as follows: when in use, the pressure roller rotates clockwise to flatten the road surface, the scraping end surface scrapes off the debris adhered to the surface of the pressure roller, and then the water in the water tank is sprayed to the surface of the pressure roller through the spray nozzle by the water pump to wash the pressure roller.

[0029] Example

[0030] like Figure 1 The road leveling machine for asphalt concrete pavement paving shown in the figure includes a vehicle body, a pressure roller 1 and a first cleaning component for cleaning the pressure roller 1. A mounting frame is provided on the vehicle body, and a hydraulic swing arm is rotatably arranged on the inner side of the mounting frame through a rotating shaft, and the pressure roller 1 is rotatably arranged on the hydraulic swing arm.

[0031] When in use, the vehicle body is driven to the road surface area to be leveled, and the pressure roller 1 is lowered by the hydraulic swing arm until it contacts the road surface.

[0032] The first cleaning assembly includes a mounting plate 2, a water tank 3 and a scraper 4. The mounting plate 2 is mounted above the pressure roller 1, and a plurality of shower heads 20 are arranged on the mounting plate 2. The water tank 3 is connected to each shower head 20 through a connecting pipe by a water pump 30, and is used to supply water to the shower head 20; the water tank 3 is arranged on the vehicle body, and the connecting pipe in this embodiment adopts a plastic hose. The scraper 4 is arranged on the mounting plate 2, and the scraper 4 has a scraping end face 40 with a triangular cross section, and the scraping end face 40 contacts the outer side surface of the pressure roller 1, and is used to scrape the sundries stuck on the outer side surface of the pressure roller 1.

[0033] Preferably, Figure 2 As shown, the plurality of nozzles 20 are evenly spaced along the longitudinal direction of the axis of the roller 1. In actual use, the plurality of nozzles 20 are arranged in a row in a direction parallel to the axis of the roller 1, so that the surface of the roller 1 can be effectively and comprehensively washed as the roller 1 rotates.

[0034] Preferably, Figure 1 As shown, the scraping end surface 40 is located behind the mounting plate 2. Figure 1 As shown, during the vehicle body's movement, the roller 1 rotates clockwise to flatten the road surface. Since the scraping end surface 40 is located behind the mounting plate 2, the scraping end surface 40 first scrapes off the debris adhering to the surface of the roller 1, and then rinses the roller 1. In actual use, the scraping end surface 40 is used to first remove a large amount of debris, which can effectively reduce the amount of liquid used in subsequent rinsing.

[0035] Preferably, Figure 1 As shown, it also includes a second cleaning component 5, which is located in front of the pressure roller 1 and is used to clean stones.

[0036] Preferably, Figure 3 As shown, the second cleaning assembly 5 is installed on the telescopic assembly 6, and the telescopic assembly 6 has a telescopic end, which is connected to the second cleaning assembly 5 and is used to drive the second cleaning assembly 5 to move in a direction perpendicular to the road surface. When in use, the second cleaning assembly 5 is moved close to the ground through the telescopic end of the telescopic assembly 6, and the second cleaning assembly 5 is raised when not in use, which can effectively avoid the problem of the second cleaning assembly 5 being damaged by collision due to its low position during transportation.

[0037] Preferably, Figure 3 , Figure 4 As shown, the second cleaning assembly 5 includes a dust collecting bin 51 , a cleaning frame 52 and a motor 53 .

[0038] The dust bin 51 has an open end, and a bucket 510 is arranged at the open end; a slide rail is arranged on the mounting frame of this embodiment, and the dust bin 51 is clamped on the slide rail and can slide up and down along the slide rail, and the telescopic end of the telescopic assembly 6 is connected to the upper surface of the dust bin 51. The cleaning frame 52 is provided with a roller 520, and a rolling brush 521 is arranged on the roller 520, and the rolling brush 521 corresponds to the position of the bucket 510; the motor 53 is arranged on the cleaning frame 52, and is connected to the roller 520, and is used to provide power to the roller 520.

[0039] Preferably, a roller is provided below the dust bin 51. In actual use, the dust bin 51 is moved downward by the telescopic assembly 6 until the position of the dust bin 51 is close to the road surface. At this time, the roller contacts the ground. When in use, the roller can provide good support for the dust bin 51 during the forward movement of the vehicle body, and prevent the dust bin 51 from causing friction with the ground, thereby affecting the forward movement of the vehicle body.

[0040] Preferably, the telescopic assembly 6 is a hydraulic cylinder, which has the advantages of being easily available and low in cost, and can be used in various complex working environments.

[0041] The working method of the above embodiment is: when in use, the vehicle body drives to the road surface area to be leveled, the pressure roller 1 is lowered to contact the road surface through the hydraulic swing arm, and the dust collection bin 51 is moved downward to the roller contacting the ground through the telescopic component 6, so that the bucket 510 is close to the ground, and the motor 53 is started to drive the roller 520 to rotate, and the stones on the road surface are swept into the bucket 510 by the rolling brush 521. Figure 1 As shown, when the vehicle body is moving, the pressure roller 1 rotates clockwise to flatten the road surface. Since the scraping end surface 40 is located behind the mounting plate 2, the scraping end surface 40 first scrapes off the debris adhered to the surface of the pressure roller 1, and then the water in the water tank 3 is sprayed to the surface of the pressure roller 1 through the spray head 20 by the water pump 30 to wash the pressure roller 1.

[0042] The specific models of the above electronic components are not specially specified, and ordinary products available on the market can be selected as long as they can meet the use requirements of the utility model.

[0043] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
