[0002] The production process of asphalt concrete involves the mixing of solid raw materials and liquid raw materials. These two types of raw materials need to be mixed according to a specific ratio to produce asphalt concrete.

[0003] The related technology (announcement number CN221714197U) discloses an automatic metering system for asphalt concrete production.

[0037] The raw materials after vibration compaction and measurement are fed into the tank body 19 through the open discharge port 12. The turned-on third motor 28 drives the second pulley 29 and the belt 30 to rotate. The belt 30 drives the first pulley 25 to rotate synchronously, so that the second rotating shaft 24 drives the fixed sleeve 26 and the stirring rod 27 to rotate, thereby mixing the raw materials in the tank body 19.
