Abstract
Description
Technical Field
[0001] This utility model relates to the field of road paving, and in particular to a quick-release paver anti-segregation rubber baffle. Background Technology
[0002] In the field of road base construction, cement-stabilized crushed stone layer is a key load-bearing layer in the pavement structure, and its construction quality directly affects the service life of the road and driving safety. With the increasing traffic volume and frequent passage of heavy vehicles, the requirements for the uniformity, density, and strength of the cement-stabilized layer are becoming increasingly stringent. However, during the paving process of the cement-stabilized layer, aggregate segregation has always been a technical bottleneck restricting the improvement of construction quality. Developing efficient and reliable anti-segregation devices has become an important direction for technological innovation in road construction.
[0003] Currently, water-stabilized layer paving construction mainly utilizes asphalt pavers or specialized stabilized soil pavers, employing a auger spreader to evenly distribute the mixture across the paving width. The auger spreader relies on the propulsive action of rotating blades to transport the mixture from the hopper to the paving surface. By adjusting the blade speed, height, and paving speed, paving operations with mixtures of different thicknesses and gradations can be achieved. Simultaneously, some equipment is equipped with a vibratory screed, utilizing high-frequency vibration and the compaction action of a tamping hammer to initially compact the paved mixture, thereby improving the density of the base course.
[0004] However, existing paving equipment struggles to effectively suppress aggregate splashing during the paving process when dealing with water-stabilized mixtures of different gradations, leading to frequent segregation problems. The separation of coarse and fine aggregates during paving results in uneven structure and inconsistent density in the water-stabilized layer, weakening the overall strength and stability of the base course, increasing the risk of reflective cracking in the pavement later, and severely impacting the construction quality and durability of road projects. Therefore, a quick-release paver anti-segregation rubber baffle is proposed to address these issues. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a quick-release paver anti-segregation rubber baffle, which aims to improve long-standing quality problems such as aggregate segregation and uneven distribution of mixture during the paving of water-stabilized layers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A quick-release paver anti-segregation rubber baffle includes a rubber plate, on both sides of which are respectively provided a rectangular iron plate and an L-shaped iron plate, and multiple iron chains are provided at the bottom of the L-shaped iron plate.
[0008] As a further description of the above technical solution:
[0009] The rectangular iron plate is internally threaded with multiple rubber fixing bolts, connecting bolt one, and connecting bolt two, with one end of each rubber fixing bolt extending through into the interior of the rubber plate.
[0010] As a further description of the above technical solution:
[0011] One end of each of the rubber fixing bolts extends through the interior of the rubber plate, and one end of each of the connecting bolts extends through the rubber plate and into the interior of the L-shaped iron plate.
[0012] As a further description of the above technical solution:
[0013] The bottom of the L-shaped iron plate is provided with multiple U-shaped buckles, and each U-shaped buckle is fixedly connected to a threaded rod on both sides of its top.
[0014] As a further description of the above technical solution:
[0015] Multiple threaded rods extend through to the top of the L-shaped iron plate, and each threaded rod has a nut threaded onto its outer wall.
[0016] As a further description of the above technical solution:
[0017] The bottoms of the multiple nuts are in contact with the outer wall of the L-shaped iron plate, and each U-shaped buckle is in contact with the iron chain.
[0018] As a further description of the above technical solution:
[0019] The bottom of the iron chain is lower than the bottom of the rubber plate, and a sealing strip is provided between the rectangular iron plate and the L-shaped iron plate.
[0020] This utility model has the following beneficial effects:
[0021] In this invention, the modular rubber sheet and iron chain work together to adapt to the needs of different road conditions and are compatible with different gradations of water-stabilized mixtures. This effectively suppresses aggregate splashing during the paving process, reduces mixture segregation, meets the requirements of green and low-carbon construction, and solves long-standing quality problems such as aggregate segregation and uneven mixture distribution during the paving of water-stabilized layers. It significantly improves the flatness and uniformity of water-stabilized layer paving, reduces the risk of later reflective cracking, and reduces material waste and rework probability.

[0028] 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.
[0029] Reference Figures 1-4This utility model provides an embodiment of a quick-release paver anti-segregation rubber baffle, comprising a rubber plate 2, with rectangular iron plates 1 and L-shaped iron plates 3 respectively arranged on both sides of the rubber plate 2. The rectangular iron plates 1 are used to fix the position of the rubber plate 2 to ensure its stability during paving. Multiple iron chains 4 are arranged at the bottom of the L-shaped iron plates 3, with a 50mm floating gap between the chain ends and the mixture accumulation surface on the outer wall of the rubber plate 2. The iron chains 4 are made of high-strength alloy steel and adopt a modular, replaceable single-section design. After wear, only partial links need to be replaced, reducing maintenance costs by 60%. The device extends the overall service life of the paving machine and is suitable for high-frequency, high-intensity water-stabilized paving operations. The L-shaped iron plate 3, in conjunction with the iron chain 4, performs an inertial swinging motion, achieving the effect of breaking up segregated clumps. The rectangular iron plate 1 has multiple rubber fixing bolts 5, connecting bolt 1 6, and connecting bolt 2 10 internally threaded. The short side of the L-shaped iron plate 3 is connected to the rectangular iron plate 1 in a stepped manner and secured by connecting bolt 2 10. The rubber fixing bolts 5 are used to secure the connection between the rubber plate 2 and the rectangular iron plate 1 to prevent loosening during paving. The lower end of the rubber plate 2 hangs freely 20-30mm above the conveyor belt. Multiple rubber fixing bolts 5 extend through the rubber plate 2 to the interior. Connecting bolt 6 is used to connect the rectangular iron plate 1 to other structural components to ensure the stability of the overall device. The rectangular iron plate 1 is attached to the side wall of the paver's discharge port and rigidly connected to the machine body's embedded parts by the Φ14mm connecting bolt 6. The flatness deviation is calibrated with a level to be ≤2mm / m. Multiple connecting bolts 10 extend through the rubber plate 2 to the interior of the L-shaped iron plate 3. Multiple U-shaped buckles 7 are provided at the bottom of the L-shaped iron plate 3. The U-shaped buckles 7 are used to fix the position of the iron chain 4 and keep it stable during swinging. To maintain stability, each U-shaped buckle 7 has a threaded rod 8 fixedly connected to both sides of its top. Multiple threaded rods 8 extend through to the top of the L-shaped iron plate 3. Each threaded rod 8 has a nut 9 threadedly connected to its outer wall. The nut 9 is used to lock the threaded rod 8, ensuring that the U-shaped buckle 7 will not shift during operation. The bottom of multiple nuts 9 is in contact with the outer wall of the L-shaped iron plate 3. Each U-shaped buckle 7 is in contact with the iron chain 4. The bottom of the iron chain 4 is lower than the bottom of the rubber plate 2. The iron chain 4 is used to dynamically crush the coarse aggregate in the mixture, improving the paving uniformity. A sealing strip is set between the rectangular iron plate 1 and the L-shaped iron plate 3.
[0030] Working Principle: During the paving process, the inertial drive of the paver's vibrating components eliminates the need for an additional power source. While ensuring uniform paving of the water-stabilized mixture, it can save 5%-8% on fuel consumption per project, meeting green and low-carbon construction requirements. It is particularly suitable for large-scale continuous paving operations of water-stabilized base courses. The flexible barrier properties of the rubber plate 2 suppress the falling speed of the mixture, while the iron chain 4 is fixed to the bottom of the L-shaped iron plate 3. The iron chain 4 maintains a 50mm floating gap with the mixture accumulation surface on the outer wall of the rubber plate 2. Through inertial swinging, the iron chain 4 breaks up segregated clumps, dynamically crushing and secondary distributing the coarse aggregate. The synergistic effect of these two components achieves secondary distribution of the mixture, effectively improving the problem of uneven material distribution during water-stabilized layer paving, reducing coarse and fine aggregate separation, and improving structural uniformity and density. Furthermore, the device's height and width can be adjusted by modularly splicing the rubber plate 2 and iron chain 4, easily adapting to different road width construction requirements. The high wear resistance and long-lasting design of the iron chain 4 further enhances its effectiveness. Designed to adapt to high-frequency operations, this system reduces maintenance costs by 60%, significantly extending the overall service life of the device. It is suitable for high-frequency, high-intensity water-stabilized paving operations. Ultimately, through the flexible barrier of rubber plate 2 and the secondary mixing action of iron chain 4, it effectively improves the uniformity of the mixture, thereby enhancing the base layer density and overall strength. Its core components are made of high-strength rubber and corrosion-resistant alloy chain links, possessing both wear resistance and corrosion resistance. It can withstand the harsh conditions of high-frequency vibration and wet cement-stabilized crushed stone, significantly improving the smoothness and uniformity of the water-stabilized layer paving, reducing the risk of later reflective cracking, and lowering material waste and rework probability. It provides an innovative quality control method for road base layer construction, possessing outstanding engineering application value. It achieves zero-energy, high-efficiency drive, reducing construction segregation from the source, ensuring stable base layer quality, improving overall road durability, and providing a more solid and uniform support foundation for subsequent asphalt surface layer construction, ultimately improving the overall quality and service life of road engineering.
