Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold paving technology for asphalt concrete, and in particular to a component of a cold paving device for asphalt concrete. Background Technology
[0002] Asphalt concrete, commonly referred to simply as asphalt, is a building material primarily used for road paving and repair. It is a mixture of asphalt and aggregates (such as crushed stone, sand, and mineral powder) in a specific ratio, formed through processes including heating, mixing, paving, and compaction. An asphalt concrete cold-laying device is a specialized piece of machinery used for laying asphalt concrete in low-temperature environments.
[0003] When using existing asphalt concrete cold paving equipment, firstly, asphalt concrete is poured into the hopper, then discharged through the outlet at the bottom of the hopper, and finally, the falling asphalt concrete is compacted by a compaction roller to complete the paving operation.
[0004] However, traditional cold-laying asphalt concrete systems have a major drawback: they cannot mix the asphalt concrete stored inside the hopper. During prolonged construction, due to the density differences between the coarse and fine aggregates and the asphalt mortar in the asphalt concrete mixture, the material may separate and stratify within the hopper. Coarse aggregates may sink, while fine aggregates and asphalt mortar may float, resulting in uneven material composition upon discharge. This unevenness reduces the overall strength and durability of the pavement, potentially leading to cracks or potholes. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an asphalt concrete cold-laying device component, aiming to improve the existing technology by enabling the mixing of asphalt concrete stored inside the hopper. During long-term construction, the density difference between coarse and fine aggregates and asphalt mortar in the asphalt concrete mixture becomes a problem.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An asphalt concrete cold paving device assembly includes a vehicle body. A storage box is fixedly connected to the upper right side of the vehicle body. A motor is installed outside the storage box. A rotating rod is fixedly connected to the output end of the motor. The rotating rod is rotatably connected inside the storage box. A drive wheel is fixedly connected to the outside of the rotating rod. A driven wheel is installed on the front side of the outside of the storage box. Two drive wheels are connected to two driven wheels via two belts. A transmission rod is fixedly connected inside each of the two driven wheels. A mixing rod is fixedly connected around the outside of each of the two transmission rods. A fixing plate is fixedly connected to the upper left side of the vehicle body. A cross plate is fixedly connected inside the two fixing plates. An adjustment component is installed on the upper part of the cross plate for adjusting the height of the paving plate.
[0008] Furthermore, the adjustment assembly includes an electric push rod, which is fixedly connected to the upper part of the horizontal plate. A moving block is fixedly connected to the output end of the electric push rod. First connecting rods are rotatably connected to both outer sides of the moving block. Fixed rods are fixedly connected to both inner sides of the horizontal plate. Slider blocks are slidably connected to the outer sides of the two fixed rods. The other ends of the two first connecting rods are rotatably connected to the upper parts of the two sliders. Second connecting rods are rotatably connected to the lower parts of the two sliders. A connecting plate is rotatably connected to the other ends of the two second connecting rods. A scraper plate is installed on the lower part of the connecting plate.
[0009] Furthermore, the upper part of the storage box is fixedly connected to a feed inlet, and the lower part of the storage box is fixedly connected to a discharge outlet.
[0010] Furthermore, a mounting bracket is fixedly connected to the front side of the storage box, and the motor is fixedly connected inside the mounting bracket.
[0011] Furthermore, a conveyor belt is installed on the middle part of the vehicle body, with one end of the conveyor belt located below the discharge port and the other end of the conveyor belt located below the vehicle body.
[0012] Furthermore, a first through hole is provided on both sides of the inside of the horizontal plate, and the two fixing rods are fixedly connected inside the two first through holes.
[0013] Furthermore, a telescopic rod is fixedly connected to the lower part of the cross plate, and the top of the telescopic rod is fixedly connected to the upper part of the connecting plate.
[0014] Furthermore, a second through hole is provided on the left side of the vehicle body, and the connecting plate is slidably connected inside the second through hole.
[0015] Furthermore, mounting rods are fixedly connected to the left side of the vehicle body, and compaction rollers are installed in the middle of the two mounting rods.
[0016] Furthermore, track wheels are installed on both sides of the vehicle body.
[0017] This utility model has the following beneficial effects:
[0018] 1. In this utility model, during the asphalt paving process, asphalt concrete is poured into a storage bin, and then the motor is started. The motor drives the rotating rod and its two fixed drive wheels to rotate. The drive wheels drive two driven wheels via belts, and the driven wheels drive two internal transmission rods and the surrounding fixed mixing rods to rotate. The rotation of the mixing rods mixes the asphalt concrete in the storage bin, preventing separation and stratification, ensuring uniform mixing of coarse and fine aggregates and asphalt mortar, avoiding weak areas and uneven pavement structure, and improving the overall strength and durability of the pavement.
[0019] 2. In this utility model, during the asphalt concrete paving process, the electric push rod is activated, causing the moving block to move. The moving block then moves the first connecting rod, which in turn pushes the slider to move relative to the fixed rod. As the slider moves, the second connecting rod moves synchronously, causing the connecting plate to move downwards, thereby adjusting the height of the scraper plate. This allows for flexible adjustment of the scraper plate height, adapting to different road surface construction needs and improving the equipment's applicability and construction flexibility.

[0026] 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.
[0027] Reference Figure 1 and Figure 4This utility model provides an embodiment of an asphalt concrete cold paving device assembly, comprising a vehicle body 1, a storage box 5 fixedly connected to the upper right side of the vehicle body 1, a motor 7 disposed outside the storage box 5, a rotating rod 8 fixedly connected to the output end of the motor 7, the rotating rod 8 being rotatably connected inside the storage box 5, a drive wheel 9 fixedly connected to the outside of the rotating rod 8, a driven wheel 11 disposed on the front side of the outside of the storage box 5, the two drive wheels 9 being connected to the two driven wheels 11 via two belts 10, a transmission rod 12 fixedly connected inside the two driven wheels 11, a mixing rod 13 fixedly connected around the outside of the two transmission rods 12, and a fixing plate 16 fixedly connected to the upper left side of the vehicle body 1. Two fixed plates 16 are internally fixedly connected to a horizontal plate 17. An adjustment component 18 is provided on the upper part of the horizontal plate 17. The adjustment component 18 is used to adjust the height of the paving plate. A feed inlet 14 is fixedly connected to the upper part of the storage box 5. A discharge outlet 15 is fixedly connected to the lower part of the storage box 5. A mounting frame 6 is fixedly connected to the front side of the storage box 5. A motor 7 is fixedly connected inside the mounting frame 6. A conveyor belt 22 is installed on the upper middle part of the vehicle body 1. One end of the conveyor belt 22 is located below the discharge outlet 15, and the other end of the conveyor belt 22 is located below the vehicle body 1. Mounting rods 3 are fixedly connected to the left side of the vehicle body 1. Compactor rollers 4 are installed in the middle of the two mounting rods 3. Track wheels 2 are installed on both sides of the vehicle body 1.
[0028] During asphalt paving, asphalt concrete is first poured into the storage bin 5. Next, the motor 7 is started, and its output drives a fixed rotating rod 8 to rotate. The rotation of the rotating rod 8 causes two externally fixed drive wheels 9 to rotate. The rotation of the two drive wheels 9 transmits power through a connected belt 10, driving two driven wheels 11 to rotate. The rotation of the two driven wheels 11 also causes two internally fixed transmission rods 12 to rotate. The rotation of the transmission rods 12 further drives the rotation of the externally fixed mixing rods 13. The rotation of the mixing rods 13 acts on the asphalt concrete inside the storage bin 5, continuously agitating it. This process ensures that the asphalt concrete inside the storage bin 5 is always in a uniformly mixed state, preventing separation and stratification of coarse and fine aggregates and asphalt mortar due to density differences. Through agitation, the problem of coarse aggregates sinking and fine aggregates floating in the asphalt concrete can be effectively avoided, ensuring the uniformity of the mixture. In this way, during the asphalt concrete paving process, material consistency can be guaranteed, avoiding weak areas and uneven structures in the paved road surface. This uniform material mixing state significantly improves the overall strength and durability of the road surface, reduces the possibility of early cracks and potholes, increases the contact area with the ground by setting track wheels 2, provides greater traction and stability, applies uniform pressure by setting compaction rollers 4 to compact the paved asphalt concrete material, and transports the asphalt concrete by setting conveyor belt 22.
[0029] Reference Figure 2and Figure 3 The adjusting assembly 18 includes an electric push rod 1801, which is fixedly connected to the upper part of the horizontal plate 17. A moving block 1802 is fixedly connected to the output end of the electric push rod 1801. First connecting rods 1803 are rotatably connected to both sides of the moving block 1802. Fixed rods 1805 are fixedly connected to both sides of the inner side of the horizontal plate 17. Sliding sliders 1804 are slidably connected to the outer sides of both fixed rods 1805. The other ends of the two first connecting rods 1803 are rotatably connected to the upper parts of the two sliding sliders 1804. The lower parts of the two sliding sliders 1804 are rotatably connected to... There is a second connecting rod 1806, and the other end of the two second connecting rods 1806 is rotatably connected to a connecting plate 1807. A scraper plate 1808 is installed on the lower part of the connecting plate 1807. The inside of the horizontal plate 17 has first through holes 19 on both sides. Two fixing rods 1805 are fixedly connected to the inside of the two first through holes 19. A telescopic rod 20 is fixedly connected to the lower part of the horizontal plate 17. The top of the telescopic rod 20 is fixedly connected to the upper part of the connecting plate 1807. A second through hole 21 is opened on the left side of the inside of the vehicle body 1. The connecting plate 1807 is slidably connected to the inside of the second through hole 21.
[0030] During asphalt concrete paving, when it is necessary to adjust the height of the scraper plate 1808, firstly, the electric push rod 1801 is activated. When the electric push rod 1801 starts working, the movable block 1802 fixed at its output end begins to move. Driven by the electric push rod 1801, the movable block 1802 moves, simultaneously driving the first connecting rods 1803 rotatably connected to both outer sides to move synchronously. The movement of the two first connecting rods 1803 drives the two sliders 1804 rotatably connected at the other end to move relative to each other outside the two fixed rods 1805. When the two sliders 1804 move relative to each other, they drive the two second connecting rods 1806 rotatably connected at the lower part to move synchronously. The movement of the second connecting rods 1806 drives the two sliders rotatably connected at the other end to move synchronously. The connecting plate 1807 moves downward, which in turn moves the scraper plate 1808 installed at the bottom, thus adjusting the height of the scraper plate 1808. This allows it to adapt to different types of road construction requirements, whether for new roads or maintenance projects, and can flexibly cope with various situations, improving the applicability of the construction equipment and enhancing the flexibility and diversity of construction. The second through hole 21 facilitates the movement of the connecting plate 1807, the first through hole 19 facilitates the installation of the fixing rod 1805, and the telescopic rod 20 assists in the movement of the connecting plate 1807.
[0031] Working Principle: During asphalt paving, asphalt concrete is first poured into the storage bin 5. Then, the motor 7 is started. The motor 7 drives the rotating rod 8 fixed at the output end to rotate. The rotating rod 8 drives the two externally fixed drive wheels 9 to rotate. The rotation of the two drive wheels 9 drives the two driven wheels 11 to rotate via two belts 10. The rotation of the two driven wheels 11 drives the two internally fixed transmission rods 12 to rotate. The rotation of the two transmission rods 12 drives the externally fixed mixing rods 13 to rotate. The rotation of the mixing rods 13 can stir the asphalt concrete stored inside the storage bin 5. This facilitates the stirring of the asphalt concrete inside the hopper during asphalt paving, preventing separation and stratification of the asphalt concrete inside the hopper, ensuring uniform mixing of coarse and fine aggregates and asphalt mortar, avoiding weak areas and uneven road structure, and improving the overall strength and durability of the road surface. Then, when it is necessary to adjust the height of the scraper plate 1808, it is done through... By activating the electric push rod 1801, the electric push rod 1801 moves the moving block 1802 fixed at the output end. The movement of the moving block 1802 moves the first connecting rod 1803 rotatably connected to the two outer sides. The movement of the two first connecting rods 1803 moves the two sliders 1804 rotatably connected at the other end relative to each other outside the two fixed rods 1805. When the two sliders 1804 move relative to each other, they move the two second connecting rods 1806 rotatably connected at the lower part synchronously. The movement of the two second connecting rods 1806 moves the connecting plate 1807 rotatably connected at the other end downward. The movement of the connecting plate 1807 moves the scraper plate 1808 installed at the lower part. This allows for easy adjustment of the height of the scraper plate 1808 during the asphalt concrete paving process, which can adapt to different types of road construction requirements. Whether it is a new road or a maintenance project, it can flexibly cope with the situation, improve the applicability of the construction equipment, and enhance the flexibility and diversity of construction.
