[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0025] See Figures 1 to 4 This embodiment proposes as follows: Figure 1 As shown, a tool for scraping off excess asphalt during the DSR process in this embodiment includes a housing 1. The housing 1 is made of ABS and has an internal cavity structure for mounting other components. The housing 1 is cylindrical in shape with one side being flat, which makes it easier to hold.

[0026] A semi-circular scraper 2 is fixedly connected to the top of the housing 1. The inner core of the scraper 2 is made of stainless steel, and a magnet 3 is set inside the stainless steel core. The magnet 3 can make the scraper 2 fit more closely to the parallel plates when working. A rubber layer 4 is wrapped around the scraper 2 and the magnet 3, which makes the scraper 2 elastic and can produce slight deformation, which is more conducive to scraping off excess asphalt in all directions. The outer surface of the rubber layer 4 is coated with Hanxiong Technology HRD8600 non-stick coating, forming a micron or nanometer-level protective film on the surface of the scraper 2. This protective film is non-adhesive to asphalt, so that the scraper 2 can scrape off excess asphalt around the two parallel plates.

[0027] A through groove 5 is provided on one side of the shell 1 where it is flat, and another through groove 5 is provided on the top of the shell 1. A push-pull key 6 is slidably connected to the through groove 5 on the side. A thermally sensitive heating scraper 7 is provided inside the shell 1. The main body of the heating scraper 7 is made of metal and its interior is filled with a thermally sensitive resistance wire 11. The outermost layer is coated with a Hanxiong Technology HRD8600 non-stick coating. The thermally sensitive resistance wire 11 is connected to the battery 8 through a circuit. The battery 8 is installed in the lower part of the shell 1. The battery 8 is equipped with a switch 9, which is located at the bottom of the shell 1. At the position where the battery 8 is installed, the shell 1 is provided with an openable battery case 10, which facilitates the fixing and replacement of the battery 8.

[0028] The pin inside the push-pull key 6 connects to the lower end of the heated scraper 7. Driven by the push-pull key 6, the top of the heated scraper 7 extends from the through slot 5 at the top of the housing 1. When the scraper 2 is working, the push-pull key 6 is placed at its lowest position, and the heated scraper 7 is retracted into the housing 1. When the scraper 2 finishes working, if there is still residual asphalt that is difficult to remove, the switch 9 is turned on, activating the thermistor 11, which in turn heats the heated scraper 7. Pushing the push-pull key 6 upwards causes the heated scraper 7 to extend from the top of the housing 1, heating the difficult-to-treat asphalt and then scraping away the remaining asphalt for a more thorough removal, ensuring a clean surface between the two parallel plates. After use, the push-pull key 6 is used to pull the heated scraper 7 back into the handle to prevent damage to the tool. The function of the heated scraper 7 is to soften the residual asphalt by increasing its temperature during operation, making it easier to scrape away excess asphalt around the two parallel plates, thus achieving secondary scraping.

[0029] The method of using a tool for scraping off excess asphalt during the DSR process in this embodiment is as follows:

[0030] During the DSR process, when it is necessary to scrape off the asphalt, place the scraper 2 part of the tool between the two parallel plates, and then use the scraper 2 to scrape off the asphalt on the two parallel plates for initial scraping. Then, use the push-pull key 6 to push out the heated scraper 7, and then touch the switch 9 to heat it. After heating is complete, use the heated scraper 7 to scrape off the remaining asphalt a second time.

[0031] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
