A discharge port 6 is used to discharge the mixed material. The coordinated operation of the first and second stirring mechanisms enhances mixing uniformity. The removable lid facilitates cleaning and maintenance of the interior of the mixing tank 1.

[0026] To further optimize the solution, the bottom of the first connecting shaft 5 is fixedly connected to one end of the mixing tank 1 with a first bevel gear 7, and the first transmission part includes a second bevel gear 8 symmetrically meshed on both sides of the first bevel gear 7, and the second bevel gear 8 is fixedly connected to the side away from the first bevel gear 7 with a second connecting shaft 9, and a fixing part is rotatably connected to the second connecting shaft 9, and the fixing part is fixed to the bottom surface of the mixing tank 1, and a cam 10 is fixedly connected to the side of the second connecting shaft 9 away from the second bevel gear 8, and the top of the cam 10 is in contact with the second stirring part.

[0034] The first and second agitator shafts 22 and 23 are staggered, creating a shear flow field during rotation. This staggered shaft design enhances material shear and convection, increasing asphalt adhesion and reducing segregation.

[0036] A further optimized solution is that the limiting member includes a first limiting rod 27 slidingly connected in the fourth slide groove 25, and a second limiting rod 28 is fixedly connected to the side of the first limiting rod 27 close to the first groove 24, and second springs 26 are symmetrically fixed on both sides of the first limiting rod 27 and the fourth slide groove 25.
