[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figures 1-9 As shown, this embodiment proposes...

[0052] A roadbed laying device for road construction, comprising

[0053] The walking frame 1 has walking components 2 at both ends of the walking frame 1, and the two walking components 2 are slidably disposed at both ends of the walking frame 1.

[0054] A first drive mechanism 3 is mounted on the walking frame 1. The first drive mechanism 3 is used for a walking component 2 to slide along the walking frame 1.

[0055] The hopper 4 is mounted on the traveling frame 1;

[0056] The top cover pipe 5 is located at the bottom of the hopper 4;

[0057] The discharge pipe 6 is slidably mounted on the upper cover pipe 5. Both the upper cover pipe 5 and the discharge pipe 6 are semi-circular. There is a discharge space between the upper cover pipe 5 and the discharge pipe 6. The bottom of the hopper 4 is connected to the discharge space. The length of the discharge pipe 6 is less than the length of the upper cover pipe 5.

[0058] The second drive mechanism 7 is set on the walking frame 1. The second drive mechanism 7 is used to drive the material feeding pipe 6 to slide along the upper cover pipe 5.

[0059] There are two baffles 8, which are respectively disposed on one side of the two walking components 2 that are close to each other.

[0060] The smoothing mechanism 9 is installed on the walking frame 1. The smoothing mechanism 9 is located behind the hopper 4 and is used to smooth the upper surface of the roadbed.

[0061] In this embodiment, to address the problem of inconvenient adjustment of the width of road paving devices in related technologies, the traveling components 2 on the traveling frame 1 are slidably configured. As the two traveling components 2 move closer or further apart, the distance between the two baffles 8 can be changed, thereby altering the width of the roadbed paving. The hopper 4 receives concrete mortar, which is discharged from the outlet space between the discharge pipe 6 and the upper cover pipe 5 and falls onto the ground. The discharge pipe 6 is driven by the second drive mechanism 7, causing it to slide. This allows the discharge pipe 6 to spread material between the two baffles 8 as it slides along the upper cover pipe 5. The slidably configured discharge pipe 6 can adapt to changes in the width between the two baffles 8, improving the equipment's versatility.

[0062] Specifically, when using the roadbed paving device for roadbed laying, the traveling component 2 can drive the traveling frame 1 to move, allowing the tanker truck to replenish the material hopper 4 in a timely manner. The concrete mortar in the hopper 4, under gravity, falls into the discharge space between the upper cover pipe 5 and the lower discharge pipe 6 and is discharged through the openings at both ends of the discharge space. The second drive mechanism 7 drives the lower discharge pipe 6 to slide back and forth along the upper cover pipe 5. During the sliding process of the lower discharge pipe 6, material is laid between the two baffles 8. Compared to the traditional method of laying material via a screw conveyor, the back-and-forth motion makes it easier to control the uniformity of the material feeding, and the speed of the lower discharge pipe 6 controls the amount of material laid, thereby controlling the height of the roadbed laying. When the width of the roadbed changes, the first drive mechanism 3 can drive the sliding component 2 to move, so that the distance between the two baffles 8 adapts to the width of the roadbed laying. The length of the upper cover pipe 5 is the same as the farthest distance between the two baffles 8. The length of the discharge pipe 6 is preferably equal to half the distance between the two baffles 8, but during use, it is advisable to ensure that the concrete mortar can be fully spread between the two baffles 8. When the width variation is small, the concrete mortar will spread around after falling, and there is no need to replace it with a discharge pipe 6 of a different length. As the traveling frame 1 moves forward, the smoothing mechanism 9 smooths the upper surface of the paved material, which facilitates the subsequent compaction of the roadbed by the road roller.

[0063] Furthermore, the first drive mechanism 3 includes

[0064] The first guide frame 10 is mounted on the traveling frame 1, and the first guide frame 10 is distributed parallel to the traveling frame 1.

[0065] The limiting frame 31 is slidably mounted on the first guide frame 10, and one end of the limiting frame 31 is connected to a walking component 2.

[0066] The first driving component 11 is mounted on the first guide frame 10;

[0067] The drive rod 12 has one end connected to the output end of the first drive member 11, which is used to drive the drive rod 12 to rotate. The other end of the drive rod 12 is slidably mounted on the limit frame 31.

[0068] In this embodiment, when the width of the road surface changes and the position of the baffle 8 needs to be adjusted, the first driving member 11 can drive the driving rod 12 to rotate, and the other end of the driving rod 12 can slide along the limiting frame 31, thereby driving the limiting frame 31 to slide along the first guide frame 10, thus changing the position of the baffle 8. Compared with other driving methods, the first guide frame 10, the limiting frame 31, and the driving rod 12 can be cleaned by water rinsing, which is convenient to clean and less prone to jamming.

[0069] Furthermore, the second drive mechanism 7 includes

[0070] The second guide frame 13 is mounted on the traveling frame 1;

[0071] The support plate 14 is slidably mounted on the second guide frame 13 at one end, and the other end of the support plate 14 is connected to the feed pipe 6.

[0072] The second drive unit 15 is mounted on the walking frame 1, and the output end of the second drive unit 15 has a drive gear.

[0073] Driven rack 16 is mounted on support plate 14 and meshes with drive gear.

[0074] In this embodiment, the drive gear of the second drive member 15 meshes with the driven rack 16, enabling the support plate 14 to slide along the second guide frame 13, thereby achieving the reciprocating movement of the feed pipe 6. The support plate 14 simultaneously shields the drive gear and the driven rack 16, preventing concrete mortar from splashing onto it and affecting the movement of the feed pipe 6 during the movement of the traveling frame 1.

[0075] Furthermore, the second guide frame 13 has a guide boss 17, and the second drive mechanism 7 also includes...

[0076] There are several guide wheels 18, which are spaced apart on the support plate 14. The outer circumference of the guide wheel 18 has a groove 19, and the guide boss 17 is located in the groove 19.

[0077] In this embodiment, to improve the stability of the feeding tube 6 during sliding, several guide wheels 18 are provided on the support plate 14. When the second driving member 15 drives the feeding tube 6 to slide by driving the driven rack 16, the guide wheels 18 slide along the guide boss 17. The guide boss 17 is adapted to the groove 19, which constrains the sliding direction of the guide wheels 18 and makes the connection between the support plate 14 and the second guide frame 13 more stable.

[0078] Furthermore, the baffle 8 has a straight segment 20 and an arc segment 21. The two baffles 8 are rotatably disposed on the side where the two traveling components 2 are close to each other, and the centers of the two arc segments 21 are far apart from each other.

[0079] The third driving component 22 is used to drive the baffle 8 to rotate.

[0080] In this embodiment, in order to improve the versatility of the roadbed paver, the baffle 8 is composed of two parts: a straight section 20 and an arc section 21. When the roadbed is laid along a straight line, the straight section 20 of the baffle 8 is parallel to the walking component 2, and the straight section 20 plays a limiting role for the concrete mortar. However, after the roadbed enters the curve, the baffle 8 is driven to rotate by the third driving component 22, so that the arc section 21 of the baffle 8 rotates towards the edge line of the roadbed. The position of the baffle 8 is adjusted in real time by the third driving component 22 so that the arc section 21 is always tangent to the edge line of the roadbed, thus completing the laying of the roadbed at the curve.

[0081] Furthermore, the smoothing agency 9 includes

[0082] Lifting component 23 is mounted on the traveling frame 1;

[0083] The first flat plate 24 is set on the lower surface of the lifting component 23, and the first flat plate 24 has a guide groove 25 at one end near the walking component 2 that is slidably set on the walking frame 1.

[0084] The second flat plate 26 is slidably disposed within the guide groove 25;

[0085] Hydraulic component 27 is located at the other end of the first trowel plate 24. Hydraulic component 27 is used to drive the second trowel plate 26 to slide along the guide groove 25.

[0086] In this embodiment, the lifting component 23 can adjust the height of the first screed plate 24 and the second screed plate 26, allowing for adjustments based on the roadbed paving height during use, thus improving the versatility of the roadbed paver. The second screed plate 26 is slidably disposed within the first screed plate 24, with an opening on the lower surface of the guide groove 25, ensuring that the lower surfaces of the first screed plate 24 and the second screed plate 26 are on the same plane, resulting in consistent flatness of the upper surface of the roadbed and facilitating subsequent compaction. The hydraulic component 27 can drive the second screed plate 26 to slide, thereby changing the total length of the first screed plate 24 and the second screed plate 26 to adapt to variations in road width. However, when paving a narrow road surface, the second screed plate 26 can be disassembled to reduce the weight of the road paver and lessen the load on the equipment during operation.

[0087] Furthermore, the front sides of the first flat plate 24 and the second flat plate 26 have guide arc surfaces 28.

[0088] In this embodiment, the guide arc surface 28 can improve the flatness of the roadbed during smoothing, and prevent the first smoothing plate 24 and the second smoothing plate 26 from suddenly contacting the upper surface of the roadbed at the beginning of the roadbed. After the traveling frame 1 moves forward, a gap will be generated at the beginning of the roadbed.

[0089] Furthermore, the first trowel plate 24 has a drive cavity 29, one end of the second trowel plate 26 is slidably connected to the drive cavity 29, and the hydraulic component 27 is connected to the drive cavity 29.

[0090] In this embodiment, the total length of the first smearing plate 24 and the second smearing plate 26 can be changed by driving one end of the second smearing plate 26 to slide along the drive cavity 29 through the hydraulic component 27. The driving method is simple and reliable.

[0091] Furthermore, the smoothing mechanism 9 also includes

[0092] There are several equalizing rakes 30, which are spaced apart and arranged on the front side of the first spreading plate 24 and the second spreading plate 26.

[0093] In this embodiment, in order to improve the efficiency and quality of roadbed smoothing, a uniform material rake 30 is used to pull the first smoothing plate 24 and the second smoothing plate 26. As the uniform material rake 30 moves forward, it passes through the laid concrete mortar, so that the upper surface of the concrete mortar is evenly distributed between the two baffles 8 before being smoothed.

[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
