[0028] Specific implementation examples are given below.

[0029] Please see Figures 1-6This utility model provides a technical solution: a road surface construction leveling device, including a plate frame 1, a roller structure 2 fixedly connected to the left side of the lower end face of the plate frame 1, a push plate 3 and a collection grid 4 fixedly connected from left to right in the middle of the lower end face of the plate frame 1, a flipping structure 5 fixedly connected to the right side of the front side and the right side of the rear side of the plate frame 1, two front-to-back linkage structures 6 are provided between the flipping structure 5 and the roller structure 2, and the plate frame 1 is located between the two linkage structures 6, and a tractor connecting frame 7 is fixedly connected to the right side of the upper end face of the plate frame 1.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the collection grid 4 includes several S-shaped grid bars 41 that are evenly distributed front and back, and all of the S-shaped grid bars 41 are fixedly connected to the plate frame 1.

[0031] The flipping structure 5 includes two second fixed plates 51, and both second fixed plates 51 are fixedly connected to the plate frame 1. The lower front side of each of the two second fixed plates 51 is provided with a second movable hole 52. The two second movable holes 52 are movably connected to a central rod 53. Several arc-shaped flip rods 54 are fixedly connected to the outer surface of the central rod 53, and the several arc-shaped flip rods 54 are staggered with several S-shaped grid rods 41.

[0032] The above scheme involves a collection grid 4 and a flipping structure 5 installed at the front of the push plate 3. When the device is in use, the flipping structure 5 can push large protrusions in the road base material to the top of the collection grid 4 for collection. Then, the push plate 3 and the roller structure 2 in the device will level the road base material, so that there will be no large protrusions on the road surface, thus ensuring the leveling quality of the road.

[0033] Furthermore, such as Figures 1-3 and Figure 6As shown, the roller structure 2 includes two first fixed plates 21, both of which are fixedly connected to the plate frame 1. Each of the two first fixed plates 21 has a first movable hole 22 on its lower front side. A first connecting shaft 23 is movably connected inside each of the two first movable holes 22. A pressure roller 24 is fixedly connected between the two first connecting shafts 23, and the bottom of the pressure roller 24 is flush with the bottom of the push plate 3. The linkage structure 6 includes a drive wheel 61, a first fixed rod 62, and a second fixed rod 63. The drive wheel 61 is fixedly connected to the first connecting shaft 23. The first fixed rod 62 is located at the middle of the front end or the middle of the rear end of the plate frame 1. The first fixed rod 62 is movably connected to the frame 1, and the second fixed rod 63 is movably connected to the second fixed plate 51. The first fixed rod 62 has a first linkage wheel 64 and a second linkage wheel 65 fixedly connected to its outer surface. The second fixed rod 63 has a driven wheel 66 and a first bevel gear 67 fixedly connected to its outer surface. The first linkage wheel 64 and the driving wheel 61 are fitted together with a first transmission belt 641. The second linkage wheel 65 and the driven wheel 66 are fitted together with a second transmission belt 651. The lower part of the first bevel gear 67 is meshed with a second bevel gear 68, and the second bevel gear 68 is inserted and fixedly connected to the outer surface of the center rod 53.

[0034] The above solution involves setting two linkage structures 6 in the device. When the device is in use, the flipping structure 5 can obtain the rotational power of the roller structure 2 during its movement through the two linkage structures 6. This eliminates the need for additional driving force to drive the flipping structure 5 during use, making the device more energy-efficient and environmentally friendly.

[0035] Working principle: First, fix the tractor connecting frame 7 to the tractor, then place the device at the height where the road surface needs to be leveled, and then drive the tractor to move the device forward. During the movement of the device, the roller structure 2 will transmit the rotational power to the flipping structure 5 through the linkage structure 6. The multiple arc-shaped flipping rods 54 in the flipping structure 5 will flip the uneven road base material, so that large protrusions in the road base material are flipped out and thrown to the upper part of the collection grid 4 for collection. Then, the push plate 3 and the roller structure 2 in the device will level the road base material, so that there are no large protrusions on the road surface. The push plate 3 is an arc-shaped inclined installation structure. When pushing the road base material, it will push the excess base material to one side of the road surface, avoiding the base material from accumulating in front of the push plate 3 and affecting the device's leveling operation of the road surface.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
