[0040] Working principle: Before using the device, first, after the asphalt is introduced into the mixing and insulation box 3, the DC motor 4 is started to drive the cylinder 5 to rotate, driving the L-shaped stirring blade 6 to stir the asphalt on both sides of the box and causing the asphalt to gather in the central area. At the same time, the L-shaped stirring blade 6 on the left will drive the cylinder 1 7 and the bevel gear 1 9 to rotate synchronously during the rotation process, and then drive the bevel gear 2 10 to rotate through the meshing action. The rotation of the bevel gear 2 10 then drives the bevel gear 3 12 to rotate through the transmission mechanism. This chain reaction ensures that the rotation directions of the cylinder 1 7 and the cylinder 2 13 are opposite, forming a staggered stirring effect. In addition, this rotation process also drives the rotation of the smooth inclined plate 8 above, further promoting the mutual penetration and fusion of the asphalt on both sides, ensuring the uniformity and consistency of the asphalt mixing.

[0041] And through the screening mechanism 2, the asphalt raw material is injected into the separation box 201 through the feed pipe 202, and then the raw material passes through the L-shaped screens 203 of different specifications in turn to achieve fine screening of components of different sizes in the asphalt raw material. For the raw materials that fail to pass through the current screen, they will gradually converge to the right under the guidance of the L-shaped screen 203. Finally, the remaining raw materials after being screened by all the screens will be concentrated to the right under the guidance of the fixed inclined block 204 at the bottom, so as to be discharged smoothly through the connecting pipe 206. At the same time, by starting the vibrator 205, its screening rate can be accelerated. This process ensures the screening effect of the asphalt raw material and the consistency of the raw material particle size distribution in the subsequent mixing process, thereby providing a solid guarantee for the stability of the final product quality.
