The top concentrator box (2031) is connected to the top of the top conveying pipe (2021), the top heater (2032) is bolted to the top of the top concentrator box (2031), and the top feed pump (2033) is connected to the top of the top discharge pipe (2022).

3. The apparatus for preparing asphalt pavement crack sealing material according to claim 1, characterized in that: The bottom concentrator assembly (205) includes a bottom concentrator box (2051), a bottom heater (2052), and a bottom feed pump (2053). The bottom concentrator box (2051) is connected to the bottom of the bottom conveying pipe (2041), the bottom heater (2052) is bolted to the bottom of the bottom concentrator box (2051), and the bottom feed pump (2053) is connected to the bottom of the bottom conveying pipe (2041).

4. A method for preparing an asphalt pavement joint sealant preparation device according to any one of claims 1-3, characterized in that: Includes the following steps: S1. Transmission and stirring: First, power on and start the transmission mechanism (1). The servo motor (1023) will drive the preparation mechanism (2) to rotate. The preparation mechanism (2) will mix and process the grouting material while rotating until the preparation mechanism (2) completes the processing of the grouting material. S2. Centralized Mixing: First, power on and start the preparation mechanism (2). Connect the two different grouting materials to the top feed pump (2033) and bottom feed pump (2053) respectively using the raw material conveying equipment. Then, inject the mixture into the top discharge pipe (2022) and bottom discharge pipe (2042) until the top concentration box (2031) and bottom concentration box (2051) are full. Then, let the transmission mechanism (1) drive the limit block (2012) to rotate. Then, the limit block (2012) will drive the lower transmission pipe (2011) and upper transmission pipe (2013) to drive the top conveying pipe (2021) and bottom conveying pipe (2041) to perform circular motion. Then, the two mixtures will move from the bottom conveying pipe (2041) to the lower transmission pipe (2011), and then from the lower transmission pipe (2041) to the bottom conveying pipe (2011). 2011) Moves to the upper transmission pipe (2013), then from the upper transmission pipe (2013) to the top connecting pipe (2023), and then from the top connecting pipe (2023) to the top conveying pipe (2021), and gradually accumulates in the top collection box (2031). Then the top heater (2032) heats the mixture, and then the mixture moves along the top conveying pipe (2021) to the mixing pipe (2061). When it flows, it drives the hollow spiral blade (2062) to rotate. When the hollow spiral blade (2062) rotates, it drives the stirring rod (2063) to move. When the stirring rod (2063) moves, it stirs the mixture. Then the mixture moves down along the mixing pipe (2061) back to the bottom discharge pipe (2042) to form a cycle until the mixing is completed.
