[0029] An asphalt paving device for road construction, such as Figures 1 to 4 As shown, it includes a base 1, a rolling wheel 3 is installed at the bottom of the base 1, a storage box 2 is fixedly installed on the top of the base 1, and the inner wall of the bottom opening of the storage box 2 is provided with at least one group of spacers 9; the inner wall of the storage box 2 is rotatably connected with a rotating shaft 7, and the outer wall of the rotating shaft 7 is provided with a plurality of paddles 8, the number of the spacers 9 in a group is a plurality, and the plurality of spacers 9 and the plurality of paddles 8 are staggered, the rotating shaft 7 and the rolling wheel 3 are driven by a linkage assembly, an inclined surface is provided in the storage box 2, and the horizontal height of the rotating shaft 7 is higher than the opening provided at the bottom end of the storage box 2.

[0030] The linkage assembly includes a first turntable 4 and a second turntable 6. The first turntable 4 is fixedly connected to one end of the rolling wheel 3, and the second turntable 6 is fixedly connected to one end of the rotating shaft 7. The same belt 5 is wound between the first turntable 4 and the second turntable 6.

[0031] The bottom of the storage box 2 is fixedly connected to a bottom shell 10 which is in communication with the storage box 2. Support wheels 11 are fixedly installed at both ends of the bottom shell 10. The bottom shell 10 is provided to facilitate the discharge of auxiliary asphalt materials, while the support wheels 11 installed at both ends of the bottom shell 10 facilitate the stable movement of the paving device.

[0032] A support guide plate 12 is provided on the inclined surface of the material storage box 2 , and a plurality of vibration springs 13 and telescopic columns 14 are fixedly connected between the bottom end of the support guide plate 12 and the inclined surface of the material storage box 2 .

[0033] When in use, the paving device is first installed on the rear of the trailer, and the asphalt to be paved is put into the storage box 2 in advance. When the paving device is pushed forward by the trailer, the rolling wheel 3 is forced to rotate so that the first turntable 4 rotates synchronously, and the first turntable 4 drives the second turntable 6 to rotate through the connection with the belt 5, and then drives the rotating shaft 7 to rotate continuously. The rotating shaft 7 rotates continuously and cooperates with the paddle 8 to stir the asphalt stored in the storage box 2, and the paddle 8 circulates through the gaps between the spacers 9, so that the asphalt is evenly discharged from the gaps and rolled by the rolling wheel 3, that is, the paving of the asphalt is achieved. At the same time, during the movement of the device, the support guide plate 12 vibrates when it is bumped, so that the asphalt is easily loosened by the bumps, thereby preventing it from solidifying.

[0034] By arranging a rotating shaft 7, paddles 8 and spacers 9 in the storage box 2, a linkage assembly connects the rolling wheel 3 and the rotating shaft 7. When the device moves, the rolling wheel 3 can cooperate with the linkage assembly to drive the rotating shaft 7 to rotate, so as to achieve stirring of the asphalt material, effectively prevent the asphalt material from condensing and becoming difficult to discharge, and avoid the load brought by the use of motor drive.

[0035] By providing an inclined surface in the storage box 2 and a support guide plate 12 on the inclined surface, and utilizing the elastic support of a plurality of vibration springs 13 and telescopic columns 14 at the bottom of the support guide plate 12, the asphalt material can be elastically supported to a certain extent, so that when the paving device is bumped or shaken during travel, the asphalt material is bumped and loosened, which can further prevent the asphalt material from solidifying.

[0036] Example 2

[0037] An asphalt paving device for road construction, based on Example 1, this embodiment makes the following improvements: Figure 3 , Figure 5 As shown, two fixing frames 15 are relatively fixed on both sides of the outer wall of the bottom end of the base 1, and the two fixing frames 15 are fixed with fixing blocks 17 on the opposite sides through fixing components. The same scraper 16 is fixed to the outer wall on the opposite side of the two fixing blocks 17, and one end of the scraper 16 is in contact with the outer wall of the rolling wheel 3, and the scraper 16 is tilted downward away from the end of the rolling wheel 3.

[0038] The fixing assembly includes a slot 18 and a fixing rod 20. The slot 18 is provided at the bottom end of the fixing frame 15. The slot 18 is L-shaped. The fixing block 17 is slidably matched with the inner wall of the slot 18. A cavity 19 is provided on the side wall at one end of the slot 18. The fixing rod 20 is slidably connected to the inner wall of the cavity 19. A through hole is provided on the outer wall of the fixing block 17 to limit the fixing rod 20. A fixing spring 21 is connected to one end of the fixing rod 20. The other end of the fixing spring 21 is connected to the inner wall of the cavity 19.

[0039] During the movement of the device, the outer wall of the rolling wheel 3 and the scraper 16 slide relative to each other, and the scraper 16 scrapes off the asphalt attached to the outer wall of the rolling wheel 3 to prevent the asphalt from being difficult to clean after it adheres to and solidifies on the outer wall of the rolling wheel 3. When the scraper 16 is worn and needs to be replaced, the fixing rod 20 is pulled to one side to disengage the fixing rod 20 from the through hole of the fixing block 17. At this time, the fixing block 17 can be taken out of the slot 18 to replace the scraper 16.

[0040] By providing a fixing frame 15, a scraper 16, a fixing block 17 and a fixing assembly, the asphalt attached to the outer wall of the rolling wheel 3 can be scraped off during the movement of the device, so as to avoid the difficulty in cleaning the asphalt after it adheres to and solidifies on the outer wall of the rolling wheel 3. At the same time, the fixing assembly facilitates replacement of the scraper 16 after a certain wear occurs.

[0041] Working principle: When in use, the paving device is first installed on the rear of the trailer, and the asphalt to be paved is put into the storage box 2 in advance. When the paving device is pushed forward by the trailer, the rolling wheel 3 is forced to rotate so that the first turntable 4 rotates synchronously, and the first turntable 4 drives the second turntable 6 to rotate through the connection with the belt 5, and then drives the rotating shaft 7 to rotate continuously. The rotating shaft 7 rotates continuously and cooperates with the paddle 8 to stir the asphalt stored in the storage box 2, and the paddle 8 circulates through the gaps between the spacers 9, so that the asphalt is evenly discharged from the gaps and is stirred by the rolling wheel 3. The asphalt is rolled, that is, the asphalt is laid. At the same time, during the movement of the device, the support guide plate 12 vibrates when it is bumped, so that the asphalt is easily loosened by the bump, preventing it from solidifying. The outer wall of the rolling wheel 3 and the scraper 16 slide relatively, and the scraper 16 scrapes off the asphalt attached to the outer wall of the rolling wheel 3 to avoid the asphalt being difficult to clean after it is attached to the outer wall of the rolling wheel 3 and solidified. When the scraper 16 is worn and needs to be replaced, the fixing rod 20 is pulled to one side to disengage the fixing rod 20 from the through hole of the fixing block 17. At this time, the fixing block 17 can be taken out of the slot 18 to replace the scraper 16.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
