Description
Technical Field
[0001] This utility model relates to the field of paver technology, specifically to an anti-adhesion device for the hopper of an asphalt paver. Background Technology
[0002] As a key piece of equipment in road construction, asphalt pavers play a vital role in modern road construction because their hoppers are used to temporarily store and transport high-temperature asphalt mixtures. With the rapid development of my country's transportation infrastructure construction, the requirements for the quality of asphalt pavement construction are constantly increasing. As an important component for the temporary storage and transportation of mixtures, the performance of the paver's hopper directly affects construction efficiency and pavement quality.
[0003] According to CN207775666U, a scraping device for the hopper of an asphalt paver is disclosed. This technology discloses a technical solution including "a scraper installed in the hopper, the scraper being in contact with the side wall of the hopper when it is in the closed state, a drive unit on the body of the asphalt paver, and a heating element in the scraper". It has the following technical effects: "After paving, the hopper is returned to the closed state, and the worker can drive the scraper to move along the side wall of the hopper through the drive unit, thereby scraping off the asphalt material adhering to the side wall, so as to reduce the generation of dead material and reduce the amount of cooled and clumped asphalt material in the hopper mixed into the normally paved asphalt material in the next paving operation, thereby improving the paving quality. The heating element heats the cooled and adhered asphalt material on the side wall of the hopper, so that the asphalt material on the side wall of the hopper melts, which can also reduce the asphalt material adhering to the scraper and improve the scraper's cleaning efficiency."
[0004] High-temperature asphalt materials tend to adhere to the inner wall of the hopper and the surface of internal components. As the operation time increases, a stubborn adhesion layer will form. This not only reduces the effective volume of the hopper, but also obstructs the flow of materials, affecting the normal transportation and uniform paving of the mixture. More seriously, the adhered asphalt material may mix into the new material, causing uneven paving and ultimately affecting the quality of road construction. Utility Model Content

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] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an anti-adhesion device for an asphalt paver hopper, including a paver body 1, a hopper mechanism 2 provided on the paver body 1 for conveying asphalt, the hopper mechanism 2 including;
[0026] The main component 21 includes a hopper 211 disposed on the paver body 1;
[0027] The vibration assembly 22 includes a housing 221 located below the outer walls at both ends of the hopper 211. A mounting plate 222 is installed at the lower end of the housing 221. A dual-axis motor 223 is installed at the top of the mounting plate 222. A disc base 224 is fixed to the output end of the dual-axis motor 223. An eccentric block 225 is installed on the outer edge of the disc base 224. Guide seats 226 are fixed to the outer walls at both ends of the housing 221. A guide rod 227 is slidably installed through the guide seat 226. A fixing plate 228 is fixed between the bottoms of the two guide rods 227 and is fixed to the hopper 211. A lower spring 229 is sleeved and installed at the lower end of the outer wall of the guide rod 227. A baffle 2210 is threaded and installed at the top of the guide rod 227. An upper spring 2211 is sleeved and installed at the upper end of the outer wall of the guide rod 227.
[0028] In this embodiment, the multi-directional vibration generated by the rotation of the eccentric block 225 on the disk base 224 driven by the output end of the dual-axis motor 223 is then accurately transmitted to the hopper 211 through the guiding mechanism composed of the guide rod 227 and the fixed plate 228. The lower spring 229 and the upper spring 2211 work together to form a bidirectional elastic buffer, which avoids rigid impact from damaging the structure of the hopper 211. At the same time, it ensures that the vibration energy is evenly transmitted to the entire inner wall of the hopper, thereby improving the anti-adhesion effect.
[0029] Specifically, the main component 21 includes gates 212 pivotally connected to both sides of the lower end of the hopper 211. Both ends of the outer wall of the hopper 211 are fixed with bearing seats 213. Hydraulic cylinders 214 are pivotally connected to the bearing seats 213, and the output end of the hydraulic cylinders 214 is pivotally connected to the outer wall of the gates 212.
[0030] In this embodiment, the opening degree of the gate 212 can be adjusted by the precise control of the hydraulic cylinder 214, thus ensuring the precise control of the outflow of asphalt mixture.
[0031] Specifically, the vibration assembly 22 also includes a reinforcing frame 215 that is horizontally fixed between the inner walls of both ends of the hopper 211, with its upper components arranged at an acute angle to the horizontal plane to form a non-depositional support surface.
[0032] In this embodiment, the reinforcement frame 215 significantly enhances the overall structural strength and deformation resistance of the hopper 211 under vibration conditions. On the other hand, the non-depositional support surface formed can effectively prevent the asphalt mixture from adhering and accumulating on the surface of the reinforcement frame 215, ensuring the smooth flow of materials.
[0033] Specifically, the vibration assembly 22 also includes mounting holes 2212 fixed at the four corners of the lower end of the housing 221, and the housing 221 is fixed to the mounting plate 222 by bolts through the mounting holes 2212.

[0036] In this embodiment, the array arrangement of heat dissipation holes 2213 effectively increases the heat dissipation surface area, promotes air convection inside the housing 221, and enables the heat generated by the dual-axis motor 223 during operation to be dissipated quickly, avoiding motor performance degradation or damage due to excessive temperature.
[0037] Specifically, the lower spring 229 is located between the bottom of the guide seat 226 and the top of the fixed plate 228, and the upper spring 2211 is located between the top of the guide seat 226 and the bottom of the baffle 2210.
[0038] The working principle and usage process of this utility model are as follows: First, the output end of the dual-axis motor 223 drives the eccentric block 225 on the disk base 224 to rotate, generating multi-directional vibration. Then, through the guide mechanism composed of guide rod 227 and fixed plate 228, the vibration energy is accurately transmitted to the hopper 211. The lower spring 229 and the upper spring 2211 work together to form a bidirectional elastic buffer, avoiding rigid impact from damaging the structure of the hopper 211. At the same time, it ensures that the vibration energy is evenly transmitted to the entire inner wall of the hopper, improving the anti-adhesion effect.
[0039] Furthermore, the reinforcement frame 215 significantly enhances the overall structural strength and deformation resistance of the hopper 211 under vibration conditions; on the other hand, the non-depositional support surface formed can effectively prevent the asphalt mixture from adhering and accumulating on the surface of the reinforcement frame 215, ensuring the smooth flow of materials.
[0040] Finally, the opening degree of the gate 212 can be adjusted by the precise control of the hydraulic cylinder 214, ensuring precise control of the asphalt mixture outflow.
