[0002] Asphalt is a widely used pavement structure binder material in road engineering. It can be mixed with mineral materials of different compositions in proportion to form a mixture to build asphalt pavements with different structures. After paving, the asphalt mixture in a soft state needs to be rolled and compacted to ensure the density and flatness of the asphalt pavement.
[0003] For example, the Chinese patent "CN220183750U" discloses "a hot rolling roller for municipal asphalt road construction". The rolling roller automatically cleans the scraper first by setting a scraper and a nozzle, and then automatically sprays the scraper on the outer wall of the roller, reducing the probability of asphalt sticking to the roller. In addition, the scraper is composed of a plate body and a detachable and replaceable blade, and the blade is used as a consumable material, so that the performance of the scraper can be guaranteed. At the same time, the blade is easy to replace, so as to ensure the rapid maintenance and replacement of the scraper. However, when the roller is not in use and is moving, the blade still abuts against the roller. Although the above blade can be disassembled, it will cause unnecessary wear, thereby accelerating the disassembly and replacement cycle, and indirectly increasing the cost. Utility Model Content

DETAILED DESCRIPTION
[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the utility model provides an asphalt mixture rolling device, including a mounting frame 2, a rolling wheel 1 arranged on the mounting frame 2, and a scraper 6 arranged on the mounting frame 2 and abutting against the rolling wheel 1, and also includes:
[0026] The adjusting assembly includes a connecting rod 16 passing through the mounting frame 2 and connected to the scraper 6, and an adjusting member passing through the mounting frame 2 and slidably engaged with the connecting rod 16. When the adjusting member moves along the axis direction of the connecting rod 16, the connecting rod 16 drives the scraper 6 away from the rolling wheel 1, or abuts against the rolling wheel 1; and
[0027] The spraying assembly is arranged on the mounting frame 2 and corresponds to the rolling surface of the rolling wheel 1 , and is used for spraying liquid onto the rolling surface of the rolling wheel 1 .
[0028] In the embodiment of the utility model, the rolling wheel 1 should be kept clean during the rolling process. Therefore, when the asphalt attached to the surface of the rolling wheel 1 needs to be removed during operation, the adjusting member is pulled along the axial direction of the connecting rod 16 through the cooperation of the adjusting assembly to make it move along the axial direction of the connecting rod 16 (first direction), so that the connecting rod 16 rotates and drives the scraper 6 to rotate, so that the end of the scraper 6 abuts against the rolling surface of the rolling wheel 1, and the asphalt attached to the rolling surface is removed, thereby ensuring the normal smoothness of the rolling wheel 1 and the quality of the asphalt road after compaction.
[0029] After the rolling is completed, the adjusting part is pushed along the axial direction of the connecting rod 16 to make it move in the opposite direction (the second direction, colinear with the first direction but opposite to the direction) along the axial direction of the connecting rod 16, so that the connecting rod 16 is reversed to drive the scraper 6 to separate from the rolling wheel 1, ensuring that the rolling wheel 1 will not affect the life of the scraper 6 when it is not in use and when moving, thereby ensuring a certain service life cycle.
[0030] Secondly, with the cooperation of the spraying assembly, after the rolling wheel 1 is cleaned by the scraper 6, water can be sprayed onto the rolling surface of the rolling wheel 1 by the spraying assembly to effectively reduce its adhesion. Specifically, Figure 1 and Figure 2 As shown, the spray assembly includes a water pipe 4 arranged on the mounting frame 2, both ends of the water pipe 4 are provided with connecting pipes 3 penetrating the mounting frame 2, and the water pipe 4 is also provided with a spray head 5 for spraying liquid. By connecting the connecting pipe 3 with an external pumping device, the liquid is transported to the water pipe 4 through the pumping device, and finally sprayed out through the spray head 5, the sprayed mist liquid is covered on the rolling surface of the rolling wheel 1 that has been cleaned, reducing its adhesion, and the mist method can facilitate the flow to prevent the mixture from cooling too quickly. The above liquid can be water, or a mixture of water and a small amount of surfactant.
[0031] Based on the above scheme, the adjusting member includes an adjusting cylinder 13 which is slidably connected to the mounting frame 2 and sleeved on the connecting rod 16, and an adjusting pin 15 which is arranged inside the adjusting cylinder 13. An adjusting groove 14 is opened on the peripheral side of the connecting rod 16. The adjusting pin 15 is slidably connected to the adjusting groove 14. When the connecting rod 16 is adjusted by the adjusting member, Figure 4 As shown, the connecting rod 16 is provided with an adjustment groove 14 on its circumference. The adjustment groove 14 is a spiral groove arranged on the circumference of the connecting rod 16. Figure 5 As shown, an adjusting pin 15 is fixedly provided on the inner side of the adjusting cylinder 13, and a stop block is provided at the end of the adjusting cylinder 13. Under the action of the stop block, the adjusting cylinder 13 can only slide on the mounting frame 2 but cannot rotate. Under the action of its rotating shaft, the scraper 6 can only rotate on the mounting frame 2 but cannot move. Therefore, when the adjusting cylinder 13 is pulled, the adjusting pin 15 in the adjusting cylinder 13 moves linearly, thereby squeezing the side of the adjusting groove 14, so that the spiral adjusting groove 14 rotates with the connecting rod 16 as the axis, thereby driving the connecting rod 16 and the scraper 6 to rotate clockwise. Conversely, pushing the adjusting cylinder 13 can make the connecting rod 16 and the scraper 6 rotate counterclockwise.
[0032] Specifically, the side of the mounting frame 2 is rotatably provided with a threaded sleeve 12, and the adjusting cylinder 13 is provided with a threaded portion 10, and the threaded sleeve 12 is meshed with the threaded portion 10. In order to ensure the stability of the adjusting cylinder 13 after adjustment, the threaded sleeve 12 can be used to lock it. When adjusting the adjusting cylinder 13, the threaded sleeve 12 is rotated to make it rotate, and cooperate with the threaded portion 10 to drive the adjusting cylinder 13 to move, and the self-locking of the adjusting cylinder 13 is completed when the threaded sleeve 12 stops rotating, so as to ensure the stability after adjustment. In order to facilitate adjustment, a nut 11 is provided on the circumference of the threaded sleeve 12. When adjusting the threaded sleeve 12, an auxiliary tool such as a wrench can be used to rotate and adjust it, which is more labor-saving.
[0033] Based on the above scheme, Figure 1 As shown, the scraper 6 includes a mounting portion 61 and a cleaning portion 62 rotatably mounted on the mounting portion 61. The mounting portion 61 is provided with an arc rod 8, and the cleaning portion 62 is sleeved on the arc rod 8. The arc rod 8 is sleeved with a spring 9, and one end of the spring 9 abuts against the side of the cleaning portion 62. In order to improve the cleaning effect between the scraper 6 and the rolling wheel 1, the scraper 6 is formed by the mounting portion 61 and the cleaning portion 62. The cleaning portion 62 can rotate on the mounting portion 61 and abut against the spring 9. When the threaded sleeve 12 is rotated for the first time to adjust the adjustment cylinder 13 so that the cleaning portion 62 abuts against the rolling wheel 1, the threaded sleeve 12 can be continuously rotated so that the mounting portion 61 continues to rotate, but the cleaning portion 62 is hindered by the rolling wheel 1 and cannot continue to move, that is, the spring 9 is compressed, and the force of the deformation is transmitted to the cleaning portion 62 through the spring 9, so that the cleaning portion 62 has a certain pressure when in contact with the rolling wheel 1, thereby improving the cleaning quality. Specifically, the cleaning portion 62 is provided with a groove 7, which can collect the scraped asphalt to a certain extent.
[0034] In summary, the present solution can remove the mixture attached to the rolling wheel 1 through the scraper 6, and spray the liquid onto the rolling wheel 1 through a number of spray heads 5 to reduce its adhesion. When the construction is completed, the threaded sleeve 12 can be rotated by adjusting the setting of the adjustment component, so that the adjustment cylinder 13 extends out of the side of the mounting frame 2 under the action of the threaded portion 10, so that the adjustment pin 15 in the adjustment cylinder 13 drives the connecting rod 16 to rotate, thereby making the scraper 6 away from the rolling wheel 1 to avoid unnecessary wear.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
