Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt processing technology, specifically to a mixing device for cold asphalt patching. Background Technology
[0002] The principle behind cold patching is to use a special asphalt mixture that remains fluid at room temperature. When this mixture is applied to cracks or potholes in a road, it quickly hardens to form a solid surface. This process does not require any heat source, hence the name "cold patching."
[0003] However, in the existing technology, traditional asphalt cold patching may not be fully mixed due to low mixing efficiency, which will ultimately affect the quality of the product. In addition, the material may adhere to the inner wall of the mixing tank during mixing, and cannot be fully mixed. If the adhered material is not cleaned, it may affect the mixing of subsequent materials. Therefore, we provide a mixing device for asphalt cold patching. Utility Model Content
[0004] The purpose of this invention is to provide a mixing device for cold asphalt patching to solve the problems mentioned in the background art.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figures 1-5 As shown in this embodiment, a mixing device for cold asphalt patching includes: a mixing mechanism 1, which includes a mixing tank 11. A support 12 is provided on the top of the mixing tank 11. Mounting bolts 13 are provided in the threaded grooves on both sides of the support 12. A motor 14 is provided on the top of the support 12. A support base 31 is fixedly connected to the outer side of the bottom of the mixing tank 11. A discharge port 32 is provided in the slot on the bottom of the mixing tank 11. The two sides of the mixing tank 11 are fixedly installed to the two sides of the inner wall of the support 12 by mounting bolts 13. The bottom of the motor 14 is fixedly installed to the top of the support 12. A rotating rod 15 is provided at the bottom of the motor 14. A mixing grid 16 is provided on the outside of the rotating rod 15. Scrapers 17 are provided on both sides of the mixing grid 16. The bottom of the rotating rod 15... The mixing tank 11 is equipped with a stirring paddle 18. The output end of the motor 14 at the bottom is fixedly connected to the top of the rotating rod 15. The bottom end of the rotating rod 15 is fixedly connected to the center of the stirring paddle 18. The stirring grid 16 is fixedly connected to the outside of the rotating rod 15. Scrapers 17 are fixedly connected to both sides of the stirring grid 16. The top of the mixing tank 11 is equipped with a stirring cover 19. A through groove 110 is opened on one side of the stirring cover 19. Slider 111 is provided on both sides of the bottom of the stirring cover 19. Sliding grooves 112 are opened on both sides of the top of the mixing tank 11. The outside of the rotating rod 15 is connected to the through groove 110. Slider 111 is fixedly connected to both sides of the bottom of the stirring cover 19. The outside of the slider 111 is slidably connected to the inner wall of the sliding groove 112. Cooling mechanisms 2 are provided in the two slots opened on the top of the stirring cover 19.
[0025] In this embodiment, when the operator needs to use the mixing device to mix the asphalt cold patch material, the mixing cover 19 needs to be removed from the mixing tank 11 through the slider 111 and the groove 112, and then the asphalt cold patch material is put into the mixing tank 11. After starting the motor 14, the rotating rod 15 is driven to rotate synchronously. Therefore, the mixing grid 16 and the mixing paddle 18 will move in a circular motion synchronously to mix the asphalt cold patch material in the mixing tank 11, ensuring the efficiency of the mixing of these materials. However, during the mixing process, some asphalt cold patch material may stick to the inner wall of the mixing tank 11 and cannot be mixed. Therefore, the rotating mixing grid 16 will drive the scraper 17 to scrape off the material adhering to the inner wall of the mixing tank 11. This not only allows them to be mixed, but also prevents the material from hardening due to long-term adhesion to the inner wall of the mixing tank 11, ensuring the cleanliness of the inner wall of the mixing tank 11 and improving the uniformity and flowability of the material.
[0026] like Figures 1-5 As shown, the cooling mechanism 2 includes a heat dissipation mesh 21. The heat dissipation mesh 21 is externally fixedly connected to a slot opened at the top of the stirring cover 19. A power supply housing 22 is fixedly installed in the slot opened at the top of the stirring cover 19. The power supply housing 22 is electrically connected to the stirring cover 19. A cooling fan 23 is fixedly installed inside the power supply housing 22.
[0027] In this embodiment, by providing cooling fans 23 in both slots of the mixing cover 19, the heat generated during mixing can be prevented from accumulating in the mixing tank 11. Therefore, the operator can supply power to the cooling fans 23 through the power supply housing 22, thereby driving the cooling fans 23 to rotate and dissipating the heat accumulated in the mixing tank 11 to the outside through the cooling fans 23. The heat dissipation net 21 can play a working role and prevent dust and impurities from affecting the cooling fans 23.
[0028] This utility model provides a mixing device for cold asphalt patching, the specific working principle of which is as follows:
[0029] When the operator needs to use the mixing device to mix the cold asphalt patching material, the mixing cover 19 needs to be removed from the mixing tank 11 via the slider 111 and the chute 112. Once the mixing cover 19 is removed, the operator can put the cold asphalt patching material into the mixing tank 11. Next, by starting the motor 14, the rotating rod 15 can be driven to rotate synchronously. As the rotating rod 15 rotates, the mixing grid 16 and the mixing paddle 18 will move in a circular motion synchronously. This circular motion will mix the cold asphalt patching material in the mixing tank 11. However, during the mixing process, some cold asphalt patching material may stick to the inner wall of the mixing tank 11 and cannot be mixed. The rotating mixing grid 16 will drive the scraper 17 to scrape off the material adhering to the inner wall of the mixing tank 11. In this way, not only can these materials be mixed, but the efficiency and quality of the entire mixing process can also be improved.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
