[0026] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0027] See also Figure 1-3 , the utility model provides a technical solution.

[0028] Embodiment 1:

[0029] Please see attached Figure 1-3 , in the specific implementation process: the automated roadbed compaction and leveling equipment includes: a roller 1 and an auxiliary structure; the auxiliary structure is installed on the roller 1;

[0030] The auxiliary structure includes: a bulldozer assembly, a soil scraper assembly and a replacement assembly;

[0031] The bulldozer assembly is mounted on the roller 1, the scraper assembly is mounted on the bulldozer assembly, and the replacement assembly is mounted on the bulldozer assembly;

[0032] It should be noted that, during the process of compacting the roadbed, after the road roller 1 moves to the designated position, the electric telescopic rod 2 installed on the support frame 3 on the road roller 1 is started, and under the action of the electric telescopic rod, the mounting frame 15 installed on the moving end of the electric telescopic rod 2 is moved downward, and the push plate 4 on the replacement component installed on the mounting frame 15 is moved downward, and the push plate 4 is brought into contact with the ground. Under the movement of the road roller 1, the push plate 4 is driven to move along the ground to flatten the soil pile on the ground.

[0033] During the process of compacting the roadbed, the earth will be contaminated on the roller of the roller 1 during the compaction process, which will cause uneven road compaction. The connection frame 5 provided on the support frame 3 is used for support, and the scraper 6 is installed on the connection block 8 and then fixed to the connection frame 5 by bolts 9, so that the scraper 6 and the roller of the roller 1 are connected to scrape the earth on the roller of the roller 1. The scraped earth falls on the guide plate 7 installed on the connection frame 5, and is guided by the guide plate 7 to the front end of the push plate 4, so that the push plate 4 can fill the material of the depression in the roadbed more fully, and the roadbed can be compacted more smoothly.

[0034] It should be noted that, since the teeth at the front end of the push plate 4 may be damaged during use, the push plate 4 needs to be inspected and replaced regularly. When replacing the damaged push plate 4, the personnel press the button 13, which drives the push rod 14 to move, thereby moving the block 12, and then squeezing the spring 11, so that the slider 10 is unlocked, and the push plate 4 slides off the mounting bracket 15 under the action of gravity. The personnel prevents the push plate 4 to be installed from being at the lower end of the mounting bracket 15, starts the electric telescopic rod 2, and during the operation of the electric telescopic rod 2 The mounting bracket 15 installed at the moving end of the electric telescopic rod 2 is driven to be pressed down. Under the action of the electric telescopic rod 2, the slider 10 is slid into the mounting bracket 15. When the slider 10 slides, the card block 12 is squeezed by the external force to collect the card block 12 into the slider 10. After the mounting bracket 15 is moved into place, the card block 12 is no longer subjected to the external force, and the spring 11 installed on the card block 12 rebounds, pushing the card block 12 outward and carding it into the mounting bracket 15, completing the installation of the push plate 4, making the operation simpler and convenient for personnel to perform installation operations.

[0035] It should be noted that the support frame 3 is provided with reinforcing ribs to effectively prevent the support frame 3 from being deformed due to excessive force; the connecting frame 5 is provided with threaded holes to facilitate the installation and fixation of the fixing bolts 9; the button 13 is provided with an anti-slip pad to increase the friction between the person's hand and the button 13 to prevent slipping.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
