Description

Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a crushed stone leveling device for roadbed construction. Background Art

[0002] The roadbed is the foundation of the road surface and bears the loads transmitted from the road surface. The area within 500mm below the top of the roadbed should be filled with soil that meets the roadbed requirements and compacted layer by layer to achieve uniformity and density.

[0003] In order to reduce the construction cost, the roadbed filling material should be local materials according to the material conditions of the project site. Most of the filling materials are crushed stone. After the crushed stone is laid on the roadbed, it needs to be leveled.

[0004] Existing devices mostly level gravel by contacting the bottom surface of the leveling end with the surface of the gravel. However, the leveling area is stationary during the leveling process. When leveling a wider roadbed, multiple reciprocating movements are required, and the efficiency is low during the leveling process. Therefore, a gravel leveling device for roadbed construction is proposed. Utility Model Content

The bottom surfaces of the two movable frames 37 are respectively fixedly connected to the top surfaces of the two groups of push plates 31. Two groups of connecting grooves are respectively opened on the side surfaces close to the two groups of push plates 31. Two slide rails 310 are respectively fixedly provided on the left and right end surfaces of the connecting block 33. The surfaces of the two slide rails 310 are respectively slidably connected to the inner walls of the two groups of connecting grooves. A wedge-shaped groove is opened on the bottom surface of the top plate 1, and a wedge block 312 is slidably provided on the inner wall of the wedge groove. The bottom surface of the wedge block 312 is fixedly connected to the top surface of the movable block 35.

[0037] In this embodiment, by providing a leveling mechanism 3, the gravel can be leveled during the roadbed construction process. During the leveling process, it can be adjusted according to the width of the roadbed, so that the leveling efficiency of the gravel can be higher.

[0038] Example 2

[0039] like Figure 1-Figure 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the lifting mechanism 2 includes four fixed sleeves 25, the bottom surface of the top plate 1 is fixedly connected to the top surfaces of the four fixed sleeves 25, the inner walls of the four fixed sleeves 25 are respectively slidably provided with four lifting rods 22, the bottom surfaces of the four lifting rods 22 are respectively fixedly provided with four moving wheels 24, the surfaces of the four fixed sleeves 25 are slidably provided with lifting frames 27, the bottom surfaces of the lifting frames 27 are respectively fixedly provided with four connecting frames 26, the inner sides of the four connecting frames 26 are respectively fixedly connected to the surfaces of the four lifting rods 22, an electric telescopic rod 21 is fixedly provided on the right side of the top plate 1, a control panel 23 is fixedly provided on the bottom surface of the output end of the electric telescopic rod 21, and the left side of the control panel 23 is fixedly connected to the right side of the lifting frame 27.

[0041] When in use, the top plate 1 is moved to the top of the gravel that needs to be leveled, and the electric telescopic rod 21 is turned on to drive the lifting frame 27 to move. During the movement of the lifting frame 27, the four connecting frames 26 can drive the four lifting rods 22 to move synchronously, so that the height of the top plate 1 can be adjusted. After the adjustment is completed, the bottom surfaces of the two sets of push plates 31 can contact the gravel. After the contact, the distance between the two sets of push plates 31 is controlled according to the area of the gravel. During the adjustment process, the double-axis threaded rod 38 is manually controlled to rotate. When the double-axis threaded rod 38 rotates, the two sets of push plates 31 can be adjusted. The two moving frames 37 move in opposite directions. When the two moving frames 37 move, they can drive the two groups of push plates 31 to move synchronously, so that the width of the two groups of push plates 31 can be adjusted. The push plates 31 can be controlled to move by the four moving wheels 24. During the movement, the motor 32 is turned on.
