Description

Technical Field

[0001] This utility model relates to the field of paver technology, and in particular to an asphalt mixture paver. Background Technology

[0002] In the field of road construction, asphalt pavers are crucial pieces of machinery. With the acceleration of urbanization and the continuous improvement of transportation infrastructure, higher demands are placed on the quality and efficiency of road paving. Asphalt pavers bear the key task of evenly spreading asphalt mixtures on the road base and initially compacting them. Their work quality directly affects the smoothness, strength, and service life of the road, playing an irreplaceable role in ensuring driving comfort and safety.

[0003] Existing asphalt pavers typically employ a relatively conventional mechanical structure. They primarily rely on a simple scraper conveyor to transport the asphalt mixture from the hopper to the screed. The screed then uses its own weight and a heating device to initially level and smooth the asphalt mixture. In the compaction stage, simple rollers are often used, applying pressure to the asphalt mixture through their rolling motion to achieve initial compaction. Their working principle is based on fundamental mechanical motion, utilizing the pushing action of the scraper and the compaction of the rollers to lay the asphalt mixture on the road surface at a specific thickness and width.

[0004] Existing asphalt pavers, due to their relatively simple compaction mechanisms, struggle to ensure uniform pressure during asphalt mixture compaction. In practice, inconsistent compaction levels frequently occur, resulting in uneven density after asphalt paving. Over-compaction in some areas leads to excessively dense asphalt mixtures, affecting subsequent performance; while under-compaction leaves numerous voids, reducing pavement strength and shortening its durability. This can cause potholes and cracks during later use, ultimately impacting road quality and lifespan. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an asphalt mixture paver, which aims to improve the problem that existing asphalt mixture pavers are unable to guarantee efficient and uniform compaction when compacting asphalt mixtures, and are prone to problems such as potholes and cracks during subsequent use, thereby affecting road quality and service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an asphalt mixture paver, comprising a mobile vehicle body, a material storage tank fixedly connected to the front end of the mobile vehicle body, wheels provided at the bottom of the mobile vehicle body, a fixed plate fixedly connected to the rear end of the mobile vehicle body, a motor fixedly connected to the upper surface of the fixed plate, a rotating shaft fixedly connected to the output end of the motor, and a reciprocating assembly provided on the outer wall of the rotating shaft;

[0007] The reciprocating assembly includes an eccentric wheel, the interior of which is fixedly connected to the outer wall of the rotating shaft. A push plate is rotatably connected to the outer wall of the eccentric wheel, and a rotating shaft is rotatably connected to the bottom of the push plate. A pressing assembly is provided on the lower surface of the rotating shaft.

[0008] Furthermore, the pressing assembly includes a sliding plate, the upper surface of which is fixedly connected to the lower surface of the rotating shaft, guide posts are slidably connected to both sides of the inner side of the sliding plate, and a pressure plate is fixedly connected to the lower surface of the sliding plate.

[0009] Furthermore, a fixing block is fixedly connected to the middle of the mobile vehicle body, a rotating column is rotatably connected to the outer wall of the fixing block, a connecting seat is fixedly connected to the outer wall of the rotating column, a push roller is rotatably connected to one end of the connecting seat, and a reset component is provided inside the rotating column, the reset component being used to drive the rotating column to reset.

[0010] Furthermore, the reset assembly includes a fixed shaft, the outer wall of which is rotatably connected to the interior of the rotating column, and a torsion spring is sleeved on the outer wall of the fixed shaft, the torsion spring being disposed at both ends of the rotating column.

[0011] Furthermore, the outer wall of the push plate is slidably connected to the inside of the fixed plate, and one end of the rotating shaft is rotatably connected to the upper surface of the fixed plate.

[0012] Furthermore, one end of the guide post is fixedly connected to the rear end of the moving vehicle body, and the other end of the guide post is fixedly connected to the lower surface of the fixed plate.

[0013] Furthermore, both ends of the fixed shaft are fixedly connected inside the fixed block, and the fixed shaft is used to support the rotating column.

[0014] Furthermore, one end of the torsion spring is fixedly connected inside the fixed block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the rotating shaft and the eccentric wheel to achieve the up-and-down reciprocating motion of the push plate. The push plate drives the sliding plate to move up and down through the rotating shaft, thereby driving the pressure plate to uniformly press down on the asphalt. The guide column effectively guides the movement of the sliding plate to ensure the stable pressing of the pressure plate, achieving efficient compaction of the asphalt mixture, effectively improving the density of the asphalt after paving, reducing voids, and ensuring the strength and durability of the paved road.

[0017] 2. In this utility model, during the operation of the paver, the moving vehicle body drives the push roller to push the asphalt mixture after it is fed, ensuring that the asphalt is even and flat during the paving process. The push roller is driven to rotate by the rotating column, and the adjustment of the torsion spring avoids damage to the push roller caused by impact from hard objects during the paving process. This effectively ensures the flatness of the asphalt paving and the stability of the mechanical equipment, and improves the construction efficiency and the quality of asphalt paving.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Reference Figure 1 - Figure 3 An embodiment of this utility model provides an asphalt mixture paver, including a mobile vehicle body 1. A storage tank 2 is fixedly connected to the front end of the mobile vehicle body 1 for storing and transporting asphalt mixture, ensuring a continuous and stable supply of asphalt during the paving process. Wheels 18 are provided at the bottom of the mobile vehicle body 1, which enable the mobile vehicle body 1 to travel smoothly on the ground and effectively support the weight of the paver. A fixed plate 3 is fixedly connected to the rear end of the mobile vehicle body 1. A motor 4 is fixedly connected to the upper surface of the fixed plate 3. A rotating shaft 5 is fixedly connected to the output end of the motor 4. The rotating shaft 5 transmits power to other components through its rotation, thereby driving the rotation of the eccentric wheel 6. A reciprocating assembly is provided on the outer wall of the rotating shaft 5.

[0026] The reciprocating assembly includes an eccentric wheel 6, the inner part of which is fixedly connected to the outer wall of the rotating shaft 5. A push plate 7 is rotatably connected to the outer wall of the eccentric wheel 6. The design of the eccentric wheel 6 allows its rotation to drive the push plate 7 to reciprocate up and down. A rotating shaft 8 is rotatably connected to the bottom of the push plate 7. The rotating shaft 8 allows the push plate 7 to move up and down effectively within a large range. A pressing assembly is provided on the lower surface of the rotating shaft 8. The pressing assembly includes a sliding plate 10. The upper surface of the sliding plate 10 is fixedly connected to the lower surface of the rotating shaft 8. Guide posts 9 are slidably connected to both sides inside the sliding plate 10. A pressure plate 11 is fixedly connected to the lower surface of the sliding plate 10.

[0027] Specifically, the asphalt mixture is first evenly laid on the ground through the storage tank 2 to prepare for subsequent compaction. At this time, the mobile vehicle 1 is started and moved forward with the wheels 18 to ensure that the paver can move smoothly along the set route. During the movement of the mobile vehicle 1, the motor 4 is started and drives the eccentric wheel 6 to rotate through the rotating shaft 5. The rotation of the eccentric wheel 6 drives the push plate 7 to move up and down. The movement of the push plate 7, together with the rotating shaft 8, pushes the sliding plate 10 to move up and down, thereby driving the pressure plate 11 to perform up and down compaction. The pressure plate 11 presses down on the asphalt laid on the ground to ensure that the compaction degree of the asphalt mixture meets the requirements and avoids the problem of loose or uneven asphalt surface. In this process, the guide column 9 plays a key role by effectively guiding the movement of the sliding plate 10, thereby ensuring the stable pressing of the pressure plate 11, making the compaction process more precise and efficient, and further improving the uniformity and density of the road surface quality.

[0028] Reference Figure 1 , Figure 4 and Figure 5A fixed block 12 is fixedly connected to the middle of the mobile vehicle body 1. The fixed block 12 is located at the center of the paver and serves as a support point for rotation and connection. A rotating column 13 is rotatably connected to the outer wall of the fixed block 12. A connecting seat 14 is fixedly connected to the outer wall of the rotating column 13. The rotating column 13 can rotate freely in its axial direction, thereby driving the rotation of the connecting seat 14. A push roller 15 is rotatably connected to one end of the connecting seat 14. The push roller 15 is used to push the paved asphalt mixture to ensure the uniformity of asphalt paving. A reset assembly is provided inside the rotating column 13. The reset assembly is used to drive the rotating column 13 to reset. The reset assembly includes a fixed shaft 1. 6. The outer wall of the fixed shaft 16 is rotatably connected to the inside of the rotating column 13. A torsion spring 17 is sleeved on the outer wall of the fixed shaft 16. The torsion spring 17 is located at both ends of the rotating column 13. The outer wall of the push plate 7 is slidably connected to the inside of the fixed plate 3. One end of the rotating shaft 5 is rotatably connected to the upper surface of the fixed plate 3. One end of the guide column 9 is fixedly connected to the rear end of the moving vehicle body 1. The other end of the guide column 9 is fixedly connected to the lower surface of the fixed plate 3. Both ends of the fixed shaft 16 are fixedly connected to the inside of the fixed block 12. The fixed shaft 16 is used to support the rotating column 13. One end of the torsion spring 17 is fixedly connected to the inside of the fixed block 12.

[0029] Specifically, during the paving process, the forward movement of the moving vehicle 1 not only propels the overall movement of the paver but also drives the rotation of the push roller 15, thereby pushing the asphalt mixture after it has been fed to be evenly laid along the paving surface of the paver. While pushing the asphalt, the push roller 15 rotates by supporting the asphalt, while the rotating column 13 rotates freely under the drive of the center of the fixed shaft 16. This design ensures that the asphalt can remain flat during the paving process and prevents uneven or excessively thick paving layers. The rotation of the push roller 15 not only provides the necessary thrust but also, through the action of the torsion spring 17, mitigates the damage that external impact forces may cause to the push roller 15. The torsion function of the spring effectively absorbs the impact of hard objects that may be encountered, avoiding damage to the push roller 15, thereby improving the durability and stability of the equipment, ensuring that the asphalt mixture can be laid evenly, and guaranteeing efficient operation and long-term stable operation of the equipment during the paving process.

[0030] Working principle: When the asphalt paver is needed, asphalt is first laid on the ground through the storage tank 2. Then, the moving vehicle 1 is started and moved with the wheels 18. During the movement of the moving vehicle 1, the motor 4 is started to drive the rotating shaft 5 to rotate, which in turn drives the eccentric wheel 6 to rotate. The eccentric wheel 6 then drives the push plate 7 to move up and down. The movement of the push plate 7, together with the rotating shaft 8, drives the sliding plate 10 to move up and down, which in turn drives the pressure plate 11 to move up and down to press and compact the asphalt on the ground. During this process, the movement of the sliding plate 10 can also be guided by the guide column 9 to achieve stable pressing.

[0031] In addition, when the mobile vehicle 1 moves, it will first drive the push roller 15 to push the asphalt after it is fed, so that the asphalt can be evenly spread on the ground. During this process, the asphalt supports the push roller 15, which will cause the push roller 15 to drive the rotating column 13 to rotate around the fixed shaft 16. At the same time, the torsion spring 17 will be torsion, effectively preventing the push roller 15 from being damaged by hard objects.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
