The device includes a cargo box with a first opening / closing device at the top and a second opening / closing device at the rear. A conveying device is located at the bottom of the cargo box, positioned in the middle. This invention utilizes the conveying device to transport all the asphalt mixture to the rear of the cargo box, leaving only a small amount of asphalt mixture inside the box in contact with the outside air, thus slowing down the cooling rate of the asphalt mixture.

[0004] While the aforementioned patent facilitates the unloading of asphalt mixtures, incomplete unloading leaves asphalt mixture residue on the inner wall of the hopper. This not only wastes materials but also causes the residue to harden and solidify inside the hopper, making cleaning difficult. Long-term accumulation reduces the effective volume of the hopper and affects transportation efficiency. Therefore, it is necessary to design a tracked unloading device for asphalt mixture transport vehicles to solve the above problems. Utility Model Content

[0018] 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.

[0019] Example like Figure 1-5 As shown, a tracked unloading device for an asphalt mixture transport vehicle includes a material box 1. Guide plates 2 are fixedly connected to both sides of the inner bottom wall of the material box 1. A motor 3 is fixedly connected to the inner bottom wall of the material box 1 near the guide plates 2. A drive roller 4 is fixedly connected to the output end of the motor 3. A track 5 is drivenly connected to the outer surface of the drive roller 4. A driven roller 6 is drivenly connected to the inner side of the track 5. Both the drive roller 4 and the driven roller 6 pass through the guide plates 2 and are rotatably connected to them. A sealed bearing 7 is provided on the outer surface of the guide plate 2 near the drive roller 4 and the driven roller 6. A bracket 8 is fixedly connected to one side of the upper surface of the track 5. A scraper 9 is fixedly connected to the outer surface of the bracket 8 by bolts.

[0020] In practical use, the guide plate 2, track 5, and scraper 9 are used to add insulation material to the inner wall of the material box 1, preventing the asphalt mixture from solidifying during transportation. The guide plate 2 guides the asphalt mixture to flow in a specific direction during unloading, preventing the mixture from accumulating or unevenly distributing within the material box 1. This ensures that the asphalt mixture falls smoothly onto the surface of the track 5. The drive roller 4, fixedly connected to the output end of the motor 3, is connected to the driven roller 6 via the track 5, forming a complete transmission system. This allows the track 5 to rotate smoothly under the drive of the motor 3, thereby moving the asphalt mixture forward and unloading it. The unloading method has... The equipment offers greater flexibility and controllability, allowing for adjustments to unloading speed and location based on construction needs. This reduces unloading time and improves construction efficiency. The scraper 9 scrapes the asphalt mixture from the hopper 1 during track 5 movement, improving unloading efficiency and ensuring uniformity. This prevents excessive asphalt mixture residue in the hopper 1. Furthermore, the scraper 9 is bolted to the bracket 8, facilitating replacement and repair in case of wear or damage, reducing maintenance difficulty and cost. The sealed bearing 7 effectively prevents asphalt mixture from entering the bearing, avoiding damage or jamming due to impurities, thus improving equipment reliability and durability.

[0021] In this embodiment, a sprocket 10 is fixedly connected to the outer surface of the driving roller 4 and the driven roller 6 near the guide plate 2, and a chain 11 is meshed with the outer surface of the sprocket 10.

[0022] In practical use, the transmission of sprocket 10 and chain 11 can ensure that all driven rollers 6 and driving roller 4 maintain the same speed, thereby making the movement of track 5 smoother and the unloading process more stable and reliable. This avoids the situation where track 5 slips or is damaged due to inconsistent speed of driven rollers 6, and improves the operating efficiency and reliability of the equipment.

[0023] In this embodiment, a tension wheel 12 is rotatably connected to the inner side of the material box 1 near the chain 11, and the tension wheel 12 is meshed with the chain 11.

[0024] In practical use, the tension wheel 12 is meshed with the chain 11. Adjusting the tension of the chain 11 ensures good meshing between the chain 11 and the sprocket 10, thereby improving the stability and reliability of the equipment operation.

[0025] In this embodiment, a first support rod 13 is fixedly connected to the top of the front of the material box 1, and a baffle 14 is rotatably connected to the outer surface of the first support rod 13.

[0026] In practical use, the baffle 14 is rotatably connected to the front of the material box 1 via the first support rod 13, covering the opening on its surface to prevent the asphalt mixture from falling off during the loading process.

[0027] In this embodiment, both sides of the outer surface of the baffle 14 are hinged with a first hydraulic rod 15, and the first hydraulic rod 15 is hinged to the material box 1.

[0028] In practical use, the opening and closing of the baffle 14 can be easily controlled by the extension and retraction of the output end of the first hydraulic rod 15. When unloading materials, the baffle 14 is closed, which can effectively prevent the asphalt mixture from falling from the front end of the material box 1, avoiding material waste and pollution of the construction site. When unloading materials, the baffle 14 can be opened for easy operation. The use of the first hydraulic rod 15 makes the control of the baffle 14 more flexible and convenient, and improves the operating efficiency of the equipment.

[0029] In this embodiment, a second support rod 16 is fixedly connected to both sides of the upper surface of the material box 1, and a cover plate 17 is rotatably connected to the outer surface of the second support rod 16.

[0030] In practical use, the cover plate 17 covers the top opening of the material box 1 through the second support rod 16, thereby enhancing the heat preservation effect of the material box 1.

[0031] In this embodiment, a support arm 18 is hinged to the outer surface of the cover plate 17, and a connecting seat 19 is hinged to the end of the support arm 18 away from the cover plate 17. A second hydraulic rod 20 is fixedly connected to the lower surface of the connecting seat 19, and the second hydraulic rod 20 is fixedly connected to the material box 1.

[0032] In practical use, the extension and retraction of the output end of the second hydraulic rod 20 can realize the opening and closing of the cover plate 17 through the connecting seat 19 and the support arm 18. After the material is loaded, the cover plate 17 is closed, which can effectively prevent the asphalt mixture from clumping due to the temperature drop during transportation, thus ensuring the quality and construction performance of the asphalt mixture. The opening and closing of the cover plate 17 is controlled by the second hydraulic rod 20, and the operation is simple and convenient.

[0033] In this embodiment, a reinforcing rib 21 is fixedly connected to the outer surface of the material box 1, and mounting plates 22 are fixedly connected to both sides of the lower surface of the material box 1.

[0034] In practical use, the reinforcing rib 21 can effectively improve the compressive strength and stability of the material box 1, enabling it to withstand larger loads and pressures, and avoid deformation or damage during transportation and unloading. The mounting plate 22 facilitates the secure installation and fixing of the entire unloading equipment on the asphalt mixture transport vehicle, ensuring the stability of the equipment during vehicle travel and preventing the equipment from loosening or falling off due to vehicle bumps or vibrations.

[0035] Working principle: In use, asphalt mixture is first loaded into the material box 1. After loading, the cover plate 17 is closed by the action of the second hydraulic rod 20 to keep it warm and prevent the asphalt mixture from clumping due to temperature drop during transportation. When the equipment moves to the designated location and needs to be unloaded, the output end of the first hydraulic rod 15 extends, the baffle 14 opens, and the output end of the motor 3 drives the drive roller 4 to rotate. The drive roller 4 drives the driven roller 6 to rotate through the track 5. During the rotation of the track 5, the asphalt mixture is moved forward and unloaded. The scraper 9 scrapes the asphalt mixture out of the material box 1 to reduce internal residue. Through the transmission of the sprocket 10 and the chain 11, it can be ensured that the multiple driven rollers 6 and the drive roller 4 rotate synchronously, so that the movement of the track 5 is more stable.
