Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a road paving and leveling machinery and equipment. Background Technology

[0002] Asphalt is a primary raw material in highway construction. Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, appearing liquid with a black surface, and is soluble in carbon disulfide. Leveling is required during asphalt pavement paving operations.

[0003] For example, the utility model patent with authorization announcement number CN218813023U discloses a paving and leveling machine for hardening the road surface of bridge and culvert construction. The device uses a trapezoidal scraper to store excess concrete, preventing it from overflowing onto the smoothed road surface. This avoids workers having to transfer the overflowing concrete and reduces labor intensity.

[0004] However, in actual use, the device cannot compact the road surface, which may result in gaps in the asphalt pavement, affecting the quality of the road surface and failing to meet the usage requirements. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 A road paving and leveling machine includes: a machine body 1, on which rollers 12 are rotatably mounted and push handles 11 are also mounted; a paving mechanism 2, installed on the front of the machine body 1, for leveling the accumulated asphalt; a compaction mechanism 3, installed on the machine body 1, for compacting the asphalt; and a roller pressing mechanism 4, installed on the machine body 1, for flattening the asphalt road surface.

[0023] The working principle of this utility model is as follows: When in use, hold the push plate and push the device to move. When the paving mechanism 2 comes into contact with the asphalt, the asphalt can be pushed flat. Then, the flattened asphalt is compacted by the compaction mechanism 3. Finally, the asphalt is rolled by the roller pressing mechanism 4 to improve the quality of the road paving and better meet the usage requirements.

[0024] As a further embodiment, the paving mechanism 2 includes a paving seat 21 installed on the front side of the machine body 1. A paving electric cylinder 23 is installed on the paving seat 21. The telescopic end of the paving electric cylinder 23 passes through the paving seat 21 and is fixed with a paving pressure plate 24. A paving guide rod 22 is also slidably inserted on the paving seat 21. The lower end of the paving guide rod 22 is fixedly connected to the upper end of the paving pressure plate 24. The front end of the paving pressure plate 24 is provided with an arc-shaped part.

[0025] The working principle of the paving mechanism 2 is as follows: During paving, the paving electric cylinder 23 extends and pushes the paving pressure plate 24 down. After the paving pressure plate 24 moves to a suitable height, the paving work can be carried out. While the device moves forward, the paving pressure plate 24 pushes the excess asphalt forward, which can effectively prevent the accumulation of asphalt and facilitate the subsequent compaction work.

[0026] As a further embodiment, the compaction mechanism 3 includes a compaction port 31 opened at the upper end of the body 1. Multiple sets of compaction guide rods 32 are slidably inserted into the body 1. A compaction pressure plate 38 is fixed to the lower end of each compaction guide rod 32, and a compaction end cap 33 is fixed to the upper end of each compaction guide rod 32. A compaction spring 34 is also fitted onto the upper half of each compaction guide rod 32. The two ends of the compaction spring 34 are respectively connected to the compaction end cap 33 and the corresponding side of the body 1. A drive assembly for driving the compaction pressure plate 38 is also installed on the body 1. The drive assembly includes a compaction mounting base 35 installed at the compaction port 31. A compaction drive wheel 36 is rotatably mounted on the compaction mounting base 35. A compaction motor 37 is also installed on the compaction mounting base 35. The output end of the compaction motor 37 is connected to the shaft end of the compaction drive wheel 36, which is elliptical in shape.

[0027] The working principle of the compaction mechanism 3 is as follows: During compaction, the compaction motor 37 is started, which drives the compaction drive wheel 36 to rotate. When the long shaft of the compaction drive wheel 36 contacts the compaction plate 38, the compaction spring 34 is compressed, and the compaction plate 38 descends to the lowest position, thus compacting the asphalt. When the short shaft of the compaction drive wheel 36 contacts the compaction plate 38, the compaction spring 34 returns to its original position, and the compaction plate 38 rises, facilitating subsequent compaction and pressing work.

[0028] As a further embodiment, the roller pressing mechanism 4 includes a roller pressing groove 41 opened on the side wall of the machine body 1, a roller pressing slide 43 slidably installed in the roller pressing groove 41, a pressure roller 42 rotatably installed between the roller pressing slides 43, and a roller pressing screw 44 threadedly inserted into the machine body 1, the lower end of the roller pressing screw 44 being rotatably connected to the upper end of the roller pressing slide 43.

[0029] The working principle of the roller pressing mechanism 4 is as follows: When in use, the roller pressing screw 44 is rotated, which drives the roller pressing slide 43 to move, thereby realizing the adjustment of the height of the pressing roller 42, which facilitates the pressing roller 42 to press the asphalt pavement and improves the paving quality of the pavement.
