[0026] like Figure 1-2 and Figure 4-7 As shown, a road leveling device is provided, including a traveling mechanism 2, both sides of the traveling mechanism 2 are transmission-connected to a crankshaft 9, the crankshaft 9 is rotationally connected to a plurality of second bearings 12, and the plurality of second bearings 12 are respectively mounted on a plurality of support plates 11, the support plates 11 can fix the second bearings 12, so that the second bearings 12 can stably mount the crankshaft 9 and maintain stable rotation of the crankshaft 9, or in other words, the crankshaft 9 is rotationally connected to the support plates 11 via the second bearings 12. A plurality of support plates 11 are fixedly connected to the bottom of the pedal 21, a plurality of rollers 10 are fixedly connected to the outside of the crankshaft 9, the crankshaft 9 is composed of a plurality of U-shaped sections, so that the crankshaft 9 can smoothly drive the frame 14 to move up and down by rotating, the rollers 10 are slidably connected in the frame 14, the opening of the frame 14 is relatively long, so that the crankshaft 9 can move in the frame 14, so that the crankshaft 9 can rotate smoothly, a vertical plate 15 is fixedly connected to the bottom of the frame 14, and the bottoms of the plurality of vertical plates 15 are fixed to the screed plate 4, a first piston rod 13 is fixedly connected to the top of one of the frames 14, the first piston rod 13 is arranged in the hydraulic cylinder 1, and liquid is arranged inside the hydraulic cylinder 1, so that the movement of the first piston rod 13 can realize the movement of the second piston rod 6 by hydraulically driving the second piston rod 6, and the hydraulic cylinder 1 is arranged in an L shape, so that the hydraulic direction can be changed. The hydraulic cylinder 1 runs through the traveling mechanism 2. A second piston rod 6 is also provided inside the hydraulic cylinder 1. One end of the second piston rod 6 is fixedly connected to a connecting block 8. A dovetail slide rail 7 is fixedly connected to the bottom of the connecting block 8. A dovetail bar 5 is fixedly connected to one side of the pedal 21. The dovetail slide rail 7 is slidably connected to the dovetail bar 5. The dovetail bar 5 can guide the dovetail slide rail 7 to keep the dovetail slide rail 7 sliding smoothly, so that the connecting member 33 moves smoothly. A push leveling assembly 3 is connected to one side of the dovetail slide rail 7. The push leveling assembly 3 includes a connecting member 33.

[0028] Example 2

[0029] On the basis of Example 1, Figure 3 As shown, the travel mechanism 2 includes a pedal 21, and the hydraulic cylinder 1 is installed through the pedal 21.

The fixing frame 28 is fixedly connected to the fixed plate 24. Both ends of one of the pressure rollers 25 are transmission-connected to both ends of the crankshaft 9 through a chain transmission structure 29. The chain transmission structure 29 is composed of two sprockets and a chain, so that the two sprockets are driven by the chain, and the two sprockets are connected to the pressure roller 25 and the crankshaft 9, so that the movement of the crankshaft 9 can be driven.

[0032] In another optional embodiment, there may be two fixed plates 24 and correspondingly, there may be one pressure roller 25. The two ends of the pressure roller 25 are rotatably connected to the two fixed plates 24 via first bearings 26 respectively, and the pressure roller 25 is transmission-connected to at least one end of the crankshaft 9 via a chain transmission structure 29.

Secondly, the controller 23 controls the motor 27 to drive the pressure roller 25 to rotate. The pressure roller 25 can move to roll the road surface, thereby leveling and compacting the road surface.

[0035] The working principle of the utility model is as follows: when leveling the road surface, the staff sits on the seat 22, and then controls the motor 27 to run through the controller 23, the motor 27 drives the pressure roller 25 to walk and level the road surface, and the pressure roller 25 also drives the chain transmission structure 29 to drive the crankshaft 9 to rotate, the crankshaft 9 drives the roller 10 to move, so that the roller 10 drives the frame 14 to move up and down, so that the frame 14 drives the vertical plate 15 and the leveling plate 4 to move up and down, so that the leveling plate 4 knocks the road surface up and down to perform vibration leveling operations, and during the up and down movement of the frame 14, the frame 14 drives the first piston rod 13 to move up and down, because the hydraulic cylinder 1 stores liquid inside, the first piston rod 13 drives the second piston rod 6 to reciprocate through the hydraulic pressure, so that the second piston rod 6 drives the connecting block 8 and the dovetail slide rail 7 to move horizontally, so that the connecting member 33 drives the connecting plate 31 and the push plate 32 to reciprocate, so that the push plate 32 can level the road surface in advance.
