[0035] An asphalt paver using a cleaning device includes a mounting frame 1, an asphalt hopper 2, a scraper 5, a compacting roller 7, and a drive roller 9; the scraper 5, the compacting roller 7, and the drive roller 9 are respectively mounted below the mounting frame 1, and the asphalt hopper 2 is mounted on the mounting frame 1, with the bottom of the asphalt hopper 2 extending downward and passing through the mounting frame 1; the asphalt hopper 2 is provided with a discharge port 21, the discharge port 21 being located on the bottom surface of the asphalt hopper 2, the scraper 5 being located between the discharge port 21 and the compacting roller 7, and further including a cleaning device 3; the cleaning device 3 includes a pusher 30, a cleaning brush driver 31, a transmission connecting plate 32, and a cleaning brush 33;

[0036] The discharge port 21 is in the shape of a long strip extending perpendicularly to the running direction of the asphalt paver;

[0037] The pusher 30 and the cleaning brush driver 31 are respectively close to the discharge port 21 and installed below the mounting frame 1; the output end of the pusher 30 extends along the direction in which the discharge port 21 extends, and the output end of the pusher 30 is connected to the outer peripheral surface of the cleaning brush driver 31;

[0038] One end of the transmission connecting plate 32 is transmission-connected to the output end of the cleaning brush driver 31, and the other end of the transmission connecting plate 32 is transmission-connected to the bottom of the cleaning brush 33. The cleaning brush 33 extends upward into the discharge port 21, and the bristles of the cleaning brush 33 are against the inner wall of the discharge port 21.

[0039] Figure 1 This is a schematic cross-sectional structural diagram of an embodiment of an asphalt paver using a cleaning device according to the present invention. The asphalt paver in the figure is running forward.

[0040] When the discharge port 21 of the asphalt hopper 2 is not discharging smoothly, or after the paving of a bucket of asphalt material is completed and before the asphalt hopper 2 is replenished with asphalt material, the cleaning brush driver 31 and the pusher 30 are started in sequence. The cleaning brush driver 31 drives the cleaning brush 33 to rotate through the transmission connecting plate 32, and the pusher 30 drives the cleaning brush driver 31 to move along the extension direction parallel to the discharge port 21, so that the cleaning brush 33 moves synchronously along the discharge port 21 and removes the asphalt material adhering to the inner wall of the discharge port 21.

[0041] Furthermore, the cleaning device 3 also includes a heating jacket 34;

[0042] The heating jacket 34 is sleeved on the bottom of the asphalt hopper 2 and surrounds the outer wall of the discharge port 21 .

[0043] like Figure 1 As shown, when the asphalt material on the inner wall of the discharge port 21 is condensed, or when the ambient temperature is low, the bottom of the asphalt hopper 2 can be heated by the heating sleeve 34 to soften the asphalt material condensed on the inner wall of the discharge port 21, and then the cleaning brush 33 can be used to remove the asphalt material adhering to the inner wall of the discharge port 21, which can improve the cleanliness of the discharge port 21 cleaned by the cleaning brush 33.

[0044] Furthermore, it also includes a support plate 22 and a plurality of support columns 23;

[0045] The mounting frame 1 includes a vertical plate 11 and a horizontal mounting plate 12;

[0046] The horizontal mounting plate 12 is provided with a hopper insertion port 121;

[0047] The front end surface of the horizontal mounting plate 12 is connected to the rear surface of the vertical plate 11;

[0048] The support plate 22 is sleeved on the outer peripheral surface of the asphalt hopper 2, and the support plate 22 extends in all directions and covers the horizontal mounting plate 12; the support plate 22 is detachably mounted on the top surface of the horizontal mounting plate 12 through a plurality of support columns 23, and the front end surface of the support plate 22 abuts against the rear surface of the vertical plate 11;

[0049] The bottom of the asphalt hopper 2 passes downward through the hopper insertion port 121 and is exposed below the horizontal mounting plate 12 ; the scraper 5 , the compacting roller 7 and the driving roller 9 are respectively mounted on the bottom surface of the horizontal mounting plate 12 .

[0050] like Figure 1-3 As shown, by covering with the support plate 22 , it is possible to prevent asphalt from dripping onto the surface of the horizontal mounting plate 12 when feeding the asphalt hopper 2 .

[0051] By lifting the support plate 22 , the asphalt hopper 2 can be pulled out from the hopper insertion port 121 , thereby improving the convenience of maintaining the cleaning device 3 and cleaning the asphalt hopper 2 .

[0052] Furthermore, it also includes a feed roller 8 and a feed roller driver;

[0053] The upper half of the asphalt hopper 2 is funnel-shaped, and the lower half of the asphalt hopper 2 is a discharge pipe; in the vertical direction, the discharge pipe is a straight pipe extending downward; in the horizontal direction, the discharge pipe extends in the direction of the discharge port 21; the discharge port 21 is located at the lower end of the discharge pipe;

[0054] The discharge pipe is inserted downward into the hopper insertion port 121;

[0055] The material roller driver frame is mounted on the outer wall of the asphalt hopper 2; the discharge roller 8 is mounted at the connection between the discharge pipe and the upper half of the asphalt hopper 2, one end of the discharge roller 8 is transmission-connected to the output end of the material roller driver, and the other end of the discharge roller 8 extends in the direction of the discharge port 21; the inner wall surface of the discharge pipe is close to the roller surface of the discharge roller 8.

[0056] like Figure 1 As shown, when the discharge port 21 of the asphalt hopper 2 is not discharging smoothly and there is still residual material in the asphalt hopper 2, before using the cleaning brush 33 to clean the discharge port 21, the material roller driver can be turned off first to stop the rotation of the discharge roller 8, and then after the cleaning brush 33 completes the cleaning of the discharge port 21, the material roller driver can be started again to allow the discharge roller 8 to continue rotating; this can avoid the continuous discharge of asphalt material from the discharge pipe during the cleaning of the discharge port 21, avoid the asphalt material in the discharge pipe from agglomerating due to squeezing, and prevent the increased difficulty of cleaning the discharge port 21 with the cleaning brush 33.

[0057] In addition, when the discharge port 21 is unobstructed, the cooperation of the material roller driver and the discharge roller 8 can improve the uniformity of the asphalt material output from the discharge pipe, which helps to improve the distribution uniformity and flatness of the asphalt material paved by the asphalt paver.

[0058] Furthermore, it also includes two lifters 4;

[0059] The two lifters 4 are respectively installed on the top surface of the horizontal mounting plate 12 , and the output ends of the two lifters 4 pass downward through the horizontal mounting plate 12 and are respectively connected to the two ends of the scraper 5 .

[0060] like Figure 1-3 As shown, by extending and retracting the output ends of the two lifters 4, the distance between the bottom surface of the scraper 5 and the construction road surface can be adjusted so that the paving thickness of the asphalt material meets the construction requirements.

[0061] Furthermore, it also includes two compacting roller connecting plates 6;

[0062] Both ends of the compacting roller 7 are rotatably connected to one end of the two compacting roller connecting plates 6, and the other ends of the two compacting roller connecting plates 6 are rotatably connected to the side surfaces of the horizontal mounting plate 12 away from the end of the driving roller 9;

[0063] The compacting roller 7 is located behind the horizontal mounting plate 12 .

[0064] like Figure 1-3 As shown, different grades of road surfaces have different pressure-bearing requirements, and compaction rollers 7 of different diameters need to be used to meet the construction and acceptance requirements of the road surface.

[0065] The compaction roller 7 is located behind the horizontal mounting plate 12 and is movably connected to the side of the horizontal mounting plate 12 through the compaction roller connecting plate 6, so that the diameter of the compaction roller 7 is not limited by the distance between the bottom surface of the horizontal mounting plate 12 and the road surface.

[0066] In summary, if Figure 1-3 In the embodiment of the utility model shown, the asphalt paver using the cleaning device can remove the asphalt material adhering to the inner wall of the discharge port 21 during the construction process through the cooperation of the brush driver 31, the pusher 30, the connecting plate 3 and the cleaning brush 33 in the cleaning device 3, thereby saving rework and repair time, improving construction efficiency, and ensuring construction progress.

[0067] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
