The rotation of the driving bevel gear 4 also drives the follower bevel gear 8 to rotate, the follower bevel gear 8 drives the connecting rod 10 to rotate through the rotating rod 9, and the connecting rod 10 drives the scraping plate 11 and the second stirring blade 12 to rotate in the heating tank 13. By arranging the second stirring blade 12 to intersect with the first stirring blade 7, all-round stirring of the asphalt material is realized, ensuring the uniformity and stirring quality of the asphalt. The scraping plate 11 can be used to scrape off the asphalt raw materials adhering to the inner wall of the heating tank 13, avoiding waste, realizing clean production, and reducing the maintenance cost.
[0029] In addition, a heating box 13 is provided inside the stirring tank 1, and a heating ring 14 is provided on the outer wall of the heating box 13. The heating ring 14 can be used to uniformly heat the asphalt material, ensuring that the asphalt is stirred at an appropriate temperature, improving the stirring efficiency. The top of the stirring tank 1 is fixedly connected through penetration with a crushing box 15. A driving pulley 16 is fixedly connected to the driving rod 3. A driven rod 17 is rotatably connected to the crushing box 15. A driven pulley 18 is fixedly connected to the driven rod 17. A transmission belt 19 is provided between the driven pulley 18 and the driving pulley 16. A driven gear 20 is fixedly connected to the driven rod 17.

The two groups of cutting blades 21 are used to initially cut and crush the asphalt material, avoiding large raw materials from affecting the stirring. A feed inlet 22 is fixedly connected through penetration to the crushing box 15. An outlet 23 is fixedly connected through penetration to the side of the stirring tank 1 away from the motor 2.

The driven pulley 18 drives the driven gear 20 to rotate through the driven rod 17. The driven gear 20 drives the cutting blade 21 to rotate. Since the two driven gears 20 are meshed with each other, the rotation directions of the two cutting blades 21 are opposite. The two cutting blades 21 are used to preliminarily cut and crush the asphalt material to avoid large raw materials affecting the mixing. The crushed asphalt material enters the heating box 13. The heating ring 14 is started to uniformly heat the asphalt material by using the heating ring 14 to ensure that the asphalt is mixed at an appropriate temperature. While the transmission rod 3 rotates, it also drives the driving bevel gear 4 to rotate. The driving bevel gear 4 drives the stirring rod 6 and the first stirring blade 7 to rotate through the driven bevel gear 5. The first stirring blade 7 is used to stir the asphalt material in the heating box 13. The rotation of the driving bevel gear 4 also drives the follower bevel gear 8 to rotate. The follower bevel gear 8 drives the connecting rod 10 to rotate through the rotating rod 9.
