The advantages are: the vehicle body can be effectively prevented from tilting with the roller, the risk of the vehicle body rolling over can be effectively reduced, the soil on the roller can be scraped off, and then with the help of a push shovel, the scraped soil can be taken away from the road surface, the working efficiency of the roller compaction is effectively improved, and the flatness of the road surface compaction is also improved.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: the above-mentioned scheme solves the problem that this device can effectively prevent the vehicle body from tilting along with the roller, effectively reduces the risk of the vehicle body rolling over, can scrape off the soil on the roller, and then cooperate with the push shovel to take the scraped soil away from the road surface, effectively improving the working efficiency of the roller compaction and improving the flatness of the road surface compaction. However, during the rolling process of the roller, impurities on the road surface will adhere to the rolling roller. When the scraper cleans the impurities on the rolling roller, the force with which the impurities adhere to the rolling roller is too great, which can easily cause serious wear of the scraper. By changing the position of the scraper, impurities with different degrees of adhesion can be cleaned to reduce the wear of the scraper. Utility Model Content

Through the mutual meshing between the first bevel gear 11 and the corresponding second bevel gear 12, when the dual-axis motor 8 is started, the two first bevel gears 11 will be driven to rotate at the same time, and thereby the second bevel gear 12 will be driven to rotate at the same time. At this time, the two bidirectional screws 13 can rotate at the same time, and the rotation of the bidirectional screws 13 can drive the corresponding fixed plates 14 to move in the opposite or reverse direction along the bidirectional screws 13 at the same time.
