[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] Example: Referring to Figures 1 to 6, one embodiment of this utility model provides an asphalt emulsification device with a wall scraping function, including a lifting regulator 1. An emulsification drive assembly 2 is drivenly connected to the output end of the lifting regulator 1. An asphalt emulsifier 3 is installed at the bottom of the end of the emulsification drive assembly 2 away from the lifting regulator 1. An asphalt heating container 4 is also provided on one side of the lifting regulator 1. The asphalt emulsifier 3 includes two sets of support base plates 5, with several sets of support connecting rods 6 connected between the two sets of support base plates 5. A rotatable link is provided between the middle parts of the two sets of support base plates 5. A first stirring shaft 7 is rotatably connected to a second stirring shaft 8 at its center. A first fixed flange 9 is mounted on one end of the second stirring shaft 8. An inner stirring head 10 is connected to the end of the second stirring shaft 8 furthest from the first fixed flange 9. A connecting base plate 11 is located at the bottom of the inner stirring head 10. Several sets of circumferentially arranged support arms 12 are arranged on the outer side of the connecting base plate 11. An auxiliary stirrer 13 is mounted on one end of each of the four sets of support arms 12. Fasteners 14 are also provided between the auxiliary stirrer 13 and one end of the support arm 12. A second stirring shaft 8 is rotatably connected to the middle of a stirring shaft 7. This structural design allows the two to cooperate in stirring. Driven by the emulsification drive component 2, the first stirring shaft 7 and the second stirring shaft 8 can achieve different rotation directions and speeds, thereby stirring the material in the asphalt emulsifier 3 in multiple directions and at multiple levels, improving the emulsification effect and efficiency. The auxiliary stirrer 13 includes an adjusting arm 15, which is structurally matched with the support arm 12. The adjusting arm 15 and the support arm 12 are connected by a plug-in joint. Positioning holes 16 are provided through both sides of the adjusting arm 15 and the support arm 12. The positioning holes 16 are structurally matched with the fasteners 14. The setting of the positioning holes 16 makes the position adjustment of the auxiliary stirrer 13 more precise. Different positioning holes 16 can be selected for fixing according to actual needs, thereby realizing the fine adjustment of the position of the auxiliary stirrer 13. The use of fasteners 14 ensures that the auxiliary stirrer 13 will not be displaced or loosened due to the impact of materials or the vibration generated by stirring during the stirring process, ensuring the stability and reliability of the stirring and scraping process.

[0028] The inner side of the adjusting arm 15 is provided with several sets of first stirring blades 17, and the outer side of the adjusting arm 15 is also equipped with a triangular scraper 18. The triangular scraper 18 is matched with the structure of the asphalt heating container 4, and the triangular scraper 18 and the asphalt heating container 4 are in contact fit. Through the structural design of the contact fit between the triangular scraper 18 and the asphalt heating container 4, the triangular scraper 18 can closely fit the inner wall of the asphalt heating container 4 during the stirring process, and can scrape off the asphalt material adhering to the inner wall. This can prevent the asphalt material from accumulating on the inner wall of the container, avoid material waste and equipment malfunction caused by asphalt residue, and also help to keep the inside of the asphalt emulsifier 3 clean, improve the emulsification effect and the service life of the equipment. A second fixed flange 19 is installed at one end of the first stirring shaft 7, and a shaft hole 20 is opened through the inside of the first stirring shaft 7. The shaft hole 20 is structurally connected to the second stirring shaft 8. In a matching manner, an outer stirring head 21 is provided at the end of the first stirring shaft 7 away from the second fixed flange 19. The outer stirring head 21 is structurally matched with the inner stirring head 10, and the outer stirring head 21 and the inner stirring head 10 are in a rotating fit. Several sets of second stirring blades 22 are also provided on the outer side of the end of the first stirring shaft 7 near the outer stirring head 21. The outer stirring head 21 is located at the end of the first stirring shaft 7 away from the second fixed flange 19, and is structurally matched with the inner stirring head 10. The two are in a rotating fit. The outer stirring head 21 rotates under the drive of the first stirring shaft 7, which can stir the asphalt material in the asphalt emulsifier 3. Due to the structural matching and rotating fit between the outer stirring head 21 and the inner stirring head 10, the two can cooperate with each other to form a synergistic stirring effect, so that the asphalt material can be fully mixed during the stirring process, improving the emulsification effect and the quality of the emulsion.

[0029] The emulsification drive assembly 2 includes a transmission housing 23. A drive motor 24 is installed in the middle of the transmission housing 23. The output end of the drive motor 24 is connected to a first bevel gear 25. Bearing seats 26 are respectively provided on both sides of the transmission housing 23 near the first bevel gear 25. The drive motor 24 is the power source of the entire emulsification drive assembly 2. It is installed in the middle of the transmission housing 23 and is connected to the first bevel gear 25 through its output end. When the equipment is started, the drive motor 24 can convert electrical energy into mechanical energy, which can provide power for the entire stirring system. One end of one set of bearing seats 26 is connected to a second bevel gear 27. A third fixed flange 28 is installed on one end of the second bevel gear 27. The third fixed flange 28 is fixedly connected to the first fixed flange 9. The other set of bearing seats 26... One end is connected to a third bevel gear 29, which meshes with the second bevel gear 27 and the first bevel gear 25. A fourth fixed flange 30 is also installed at one end of the third bevel gear 29, which is fixedly connected to the second fixed flange 19. Through the meshing connection between the second bevel gear 27 and the first bevel gear 25, and the fixed connection between the third fixed flange 28 and the first fixed flange 9, it is ensured that the second mixing shaft 8 and the first mixing shaft 7 can rotate synchronously in opposite directions. Due to the meshing characteristics of the gears, the first mixing shaft 7 can keep the rotation speed consistent with the second mixing shaft 8, thereby ensuring that the asphalt material can be uniformly mixed during the mixing process, avoiding the problem of uneven mixing or poor emulsification effect caused by asynchronous rotation speed.

[0030] Working principle: The asphalt emulsification equipment designed in this scheme drives the first bevel gear 25 to rotate by starting the drive motor 24. The first bevel gear 25 meshes with the second bevel gear 27 and the third bevel gear 29, thereby driving the second bevel gear 27 and the third bevel gear 29 to rotate. The second bevel gear 27 is fixedly connected to the first fixed flange 9 through the third fixed flange 28, thereby driving the second stirring shaft 8 to rotate. The third bevel gear 29 is fixedly connected to the second fixed flange 19 through the fourth fixed flange 30, thereby driving the first stirring shaft 7 to rotate. Due to the first bevel gear... The meshing relationship between wheel 25 and the second bevel gear 27 and the third bevel gear 29, and the rotation directions of the first stirring shaft 7 and the second stirring shaft 8 are opposite. Through the outer stirring head 21 and the second stirring blade 22 installed on the first stirring shaft 7, the asphalt material being processed by emulsification can be rotated and stirred in the forward direction. The outer stirring head 21 and the inner stirring head 10 are structurally matched and are rotated together. When the outer stirring head 21 rotates in the forward direction, it can effectively stir the asphalt material. At the same time, the second stirring blade 22 on the outside of the first stirring shaft 7 also participates in the stirring, further enhancing the stirring effect.

[0031] The asphalt emulsification equipment designed in this scheme, through components such as the inner mixing head 10 and auxiliary mixer 13 mounted on the second mixing shaft 8, can perform counter-rotating mixing of the asphalt material being emulsified. When the inner mixing head 10 rotates in the counter-rotating direction, it can deeply mix the asphalt material, making it fully mixed with water and emulsifier. The auxiliary mixer 13 is connected to the support arm 12 through the adjustment arm 15. The first mixing blade 17 on the inner side of the adjustment arm 15 further enhances the mixing effect. In this scheme, while performing counter-rotating mixing of the asphalt material being emulsified, the auxiliary mixer 13 can also scrape and clean the asphalt material adhering to the asphalt heating container 4. A triangular scraper 18 is installed on the outside of the auxiliary mixer 13. The triangular scraper 18 matches the structure of the asphalt heating container 4 and contacts the inner wall of the container. During the mixing process, the triangular scraper 18 can effectively scrape off the asphalt material adhering to the inner wall of the container, preventing its residue and ensuring the smooth progress of the emulsification process.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
