DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] As shown in Figure 1 , Figure 3 , Figure 4 , the asphalt mixing device with damping function in the first embodiment of the present application comprises a stirring pipe 2 for containing asphalt and realizing mixing operation, and a damping structure 1 arranged below the stirring pipe 2 to play a buffering role. A plurality of first support rods 7 are connected between the damping structure 1 and the stirring pipe 2 in a fixed connection mode and are uniformly distributed in the circumferential direction. The number of the first support rods 7 is preferably three. The connection structure and the number setting can form a stable support effect on the stirring pipe 2 to prevent it from deviating or shaking during the asphalt stirring process.

[0021] As shown in Figure 1 , Figure 4 , the stirring pipe 2 is a main body circular pipe, and a bottom plate 3 matched with the stirring pipe 2 and slidable is arranged inside the main body. The stirring pipe 2 and the bottom plate 3 form a cylindrical stirring cavity, and the asphalt material to be stirred is poured into the cylindrical stirring cavity through an opening at the top end of the stirring pipe 2, so that the first stirring part 5 driven by the driving part 4 described in detail below can stir the asphalt material.

[0022] The stirring pipe 2 has a discharge slot 14 at the top end of the main body outside, for discharging the asphalt mixture stirred in the stirring pipe 2, and has a convex ring 15 at the bottom end inside. When the asphalt material is stirred, the convex ring 15 bears the weight of the material from the bottom plate 3. The top end of the first support rod 7 is connected with the bottom of the convex ring 15, and the bottom end is arranged at the top of the damping structure 1. The first support rod 7 is a circular pipe, and has a sliding hole 20 corresponding to the circular pipe on the convex ring 15. An auxiliary rod 19 is arranged inside the circular pipe and penetrates through the sliding hole 20 and is welded on the bottom plate 3 at the top. The auxiliary rod 19 can limit the rotation direction of the bottom plate 3 when the first stirring part 5 rotates to stir the asphalt material, so as to prevent the bottom plate 3 from rotating synchronously with the stirring action.

[0023] As shown in Figure 4 , the driving part 4 mainly comprises a motor. The motor has a rotating shaft 11, and the motor is arranged at the center position of the bottom of the bottom plate 3. The rotating shaft 11 penetrates through the bottom plate 3 and extends into the stirring pipe 2, and the first stirring part 5 is arranged on the rotating shaft 11. The motor drives the first stirring part 5 to rotate in the cylindrical structure formed by the stirring pipe 2 and the bottom plate 3, so as to fully stir and mix the asphalt material.

[0024] As shown in Figure 3 ,Figure 4 As shown in detail, the first stirring member 5 is provided with at least three, preferably three, which are evenly distributed around the rotating shaft 11. The first stirring member 5 is composed of a stirring arm 12 and a scraper 13. The stirring arm 12 is bent downward, with its top end welded to the outer wall of the rotating shaft 11 and its bottom end connected to the scraper 13. When stirring the asphalt material, the stirring arm 12 rotates to stir the asphalt material. The scraper 13 is rectangular and inclined, with its bottom end in contact with the bottom plate 3. The horizontal lengths of the three stirring arms 12 corresponding to the scraper 13 are equal in length and increase in order, so that the trajectory formed by the scraper 13 during rotation covers the bottom plate 3, thereby enabling the scraper 13 to fully scrape the asphalt material adhering to the bottom plate 3.

[0025] As shown in Figure 1 , Figure 3 , Figure 4 , at least three first electric telescopic rods 8 are provided between the bottom plate 3 and the damping structure 1, preferably three in the present application, and evenly distributed. When the first electric telescopic rod 8 is extended, it pushes the bottom plate 3 to slide upward in the stirring pipe 2, not only pushing the completed material out of the stirring pipe 2, but also scraping off the asphalt material adhering to the inner wall of the stirring pipe 2.

[0026] As shown in Figure 4 , the damping structure 1 is composed of a support plate 17, a bottom box 16 and springs 18. The bottom box 16 is a rectangular parallelepiped with an open top. The support plate 17 is installed in the bottom box 16 and matches the opening. The springs 18 are provided in multiple numbers, evenly distributed in the bottom box 16 and connected to the bottom of the support plate 17. The first electric telescopic rod 8 and the first support rod 7 are both fixedly connected above the support plate 17, forming a stable support. When the first stirring member 5 rotates, the damping structure 1 dampens the vibration generated by the device, preventing the components on the device from loosening due to long-term vibration.

[0027] In actual operation, the operator first pours the asphalt material to be stirred into the cylindrical stirring cavity formed by the stirring pipe 2 and the bottom plate 3 from the top opening of the stirring pipe 2, then starts the motor of the driving member 4, which drives the rotating shaft 11 and the first stirring member 5 to rotate, the stirring arm 12 stirs the material, and the scraper 13 scrapes off the adhering material on the bottom plate 3, achieving full mixing of the material; after stirring is completed, the first electric telescopic rod 8 is started to push the bottom plate 3 to slide upward, while the first stirring member 5 continues to stir, pushing the mixed asphalt material out of the discharge slot 14, thereby completing the material discharge and cleaning of the inner wall of the stirring pipe 2; throughout the stirring process, the springs 18 of the damping structure 1 continuously absorb vibration, ensuring stable operation of the device.

[0028] Figures 5-8As shown, the asphalt mixing device with damping function is the second embodiment of the present application. Compared with the first embodiment, the device still revolves around the stirring pipe 2, the damping structure 1 and the related support and stirring components, but changes are made in some key parts to improve the stirring effect of the device on asphalt materials and the overall stability and practicality.

[0029] The main structure of the stirring pipe 2 is still a circular pipe, and the top end is open for feeding asphalt materials, and the top end is provided with a discharge chute 14 for discharging the mixed materials.

[0030] The bottom plate 3 is an important component for carrying materials and participating in the stirring process, and a new connection relationship is established between the bottom plate 3 and the support plate 17 on the damping structure 1. At least three second electric telescopic rods 10 are fixedly connected between the two, and the second electric telescopic rods 10 are preferably three in the present application. This connection mode not only enables the second electric telescopic rods 10 to support and fix the stirring pipe 2, but also ingeniously participates in the material processing link in the stirring process. When the bottom plate 3 is in contact with the convex ring 15 at the bottom of the stirring pipe 2, the second electric telescopic rods 10 are in an extended state. Through the setting of this state, the structural stability of the entire device during normal material carrying and stirring is ensured, and the relative position relationship of the components is ensured.

[0031] In addition, at least three second support rods 9 are connected between the bottom plate 3 and the support plate 17 on the damping structure 1, and the second support rods 9 are preferably three in the present application. These second support rods 9 are evenly distributed, and their main function is to form a stable support for the bottom plate 3. During the operation of the device, the second support rods 9 share the weight borne by the bottom plate 3 and the force from the stirring action, further enhancing the stability of the bottom plate 3 and making the entire stirring process more stable and reliable.

[0032] Moreover, when the second electric telescopic rods 10 are retracted, the stirring pipe 2 and the bottom plate 3 will slide relative to each other. By utilizing this relative sliding, the bottom plate 3 can scrape the asphalt adhering to the inside of the stirring pipe 2, effectively avoiding the residue of asphalt, improving the utilization rate of materials and the cleanliness of the device, and creating good conditions for subsequent stirring operations.

[0033] Figure 6 、 Figure 8As shown, a plurality of second stirring pieces 6 are mounted on the rotating shaft 11, which are evenly distributed around the rotating shaft 11, and three are preferentially arranged in the application. The second stirring pieces 6 have a unique fan-shaped design, one side of which is connected with the rotating shaft, one end of which is connected with the rotating shaft, and the other end of which is in contact with the inside of the stirring pipe. The bottom end is in contact with the bottom plate 3. This design enables the asphalt attached to the top of the bottom plate 3 to be scraped synchronously when the second stirring pieces 6 rotate. In this way, while the material is stirred, the cleaning function of the asphalt is further strengthened to prevent the asphalt from accumulating on the bottom plate 3, ensuring the uniformity of the material stirring and helping to improve the stirring efficiency, so that the asphalt material can be more fully mixed.

[0034] In actual operation, after the asphalt material is poured into the top opening of the stirring pipe 2 by the operator, the motor is started, and the rotating shaft 11 drives the fan-shaped second stirring pieces 6 to start rotating to stir and mix the material. At the same time, the second stirring pieces 6 scrape the asphalt attached to the bottom plate 3 when rotating to ensure the relative cleanliness of the surface of the bottom plate 3. When the stirring is completed, the second electric telescopic rod 10 is retracted to make the stirring pipe 2 slide relative to the bottom plate 3, so that the bottom plate 3 scrapes the residual asphalt in the stirring pipe 2 again, and then the material can be discharged through the discharge slot 14. During the entire stirring and related operation process, the damping structure 1 continuously plays a damping role to ensure the stability of the device as a whole, avoiding damage to the parts or affecting the stirring effect due to vibration.

[0035] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
