Foaming machine for manufacturing asphalt

A foaming machine for asphalt manufacturing comprises an outer frame structure and a water spraying structure, the outer frame structure comprises an outer frame, the foaming machine for asphalt manufacturing further comprises an air spraying structure, a connecting structure, a positioning structure and a driving structure, and the air spraying structure comprises a rotating frame, a one-way valve, a stirring frame, a fixed block, a first spring, a movable frame and a balancing weight arranged at the end of the movable frame. By arranging the one-way valve, air can smoothly flow downwards soas to make full contact with asphalt, and on the other hand, when air stops flowing, air below can be prevented from flowing upwards, so that a water seal phenomenon can be generated at the fourth through hole in the lower surface of the movable frame, water and asphalt are prevented from entering the movable frame. The asphalt is fully and comprehensively utilized, waste of asphalt resources is reduced, and the fourth th
