Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a road paving device for road and bridge construction, including a cart 1, a roller 2 and a cleaning mechanism 3, at least one roller 2 is arranged on the cart 1, the cleaning mechanism 3 is arranged on the cart 1, and the cleaning mechanism 3 is located at the front end of the cart 1, the cleaning mechanism 3 includes a push plate 31, and two guide surfaces 311 are provided on one side of the push plate 31 facing the travel direction of the cart 1, one side of the two guide surfaces 311 overlaps, and the other sides of the two guide surfaces 311 extend obliquely from the front end of the cart 1 to both sides of the rear end of the cart 1.
[0023] In this embodiment, the roller 2 and the cleaning mechanism 3 are arranged on the cart 1, and the cleaning mechanism 3 is located in front of the cart 1, that is, after the cleaning mechanism 3 cleans the road surface, it rolls the road surface through the roller 2. At the same time, the push plate 31 in the cleaning mechanism 3 has two guide surfaces 311, one side of the two guide surfaces 311 overlaps, and the other side of the two guide surfaces 311 extends obliquely from the front end of the cart 1 to the rear end of the cart 1, thereby gathering the debris on the road surface toward the two sides of the cart 1, and then the roller 2 rolls the cleaned road surface to improve the finishing effect of the local road surface.
[0024] Optionally, the bottom surface of the push plate 31 is configured as a scraper portion 312, and the scraper portion 312 is configured to be in sliding contact with the road surface. Figure 2 As shown, the scraper portion 312 is configured as a blade surface, so that when the cart 1 is pushed, the scraper portion 312 can contact the road surface and push away small stones and other debris on the road surface, and then the roller 2 rolls the cleaned road surface to improve the finishing effect of the local road surface.
[0025] Optionally, the cart 1 includes a frame 11 and four wheels 12 , and the four wheels 12 are respectively connected to two sides of the frame 11 .
[0026] Optionally, the cart 1 further includes a handle 13 , which is connected to the frame 11 and is arranged away from the cleaning mechanism 3 .
[0027] Optionally, the cleaning mechanism 3 further includes a cross bar 32 , a support bar 33 and a buffer component, the cross bar 32 is connected to the frame 11 via the buffer component, the cross bar 32 is connected to one end of the support bar 33 , and the other end of the support bar 33 is used to connect to the push plate 31 .
[0028] In this embodiment, the buffer component provided on the cleaning mechanism 3 enables the cart 1 to be pushed smoothly.
