Technical Field

[0001] The utility model relates to the field of crushing equipment, in particular to asphalt regeneration crushing equipment. Background Art

[0002] Asphalt recycling refers to a series of operations such as digging up, recycling, crushing, and screening old asphalt roads. After the old asphalt is recycled and mixed with new asphalt in a certain proportion, a mixture can be formed and re-paved on the road surface.

[0003] Asphalt recycling can increase the viscosity and mixing effect of asphalt materials, increase the service life and smoothness of roads. Asphalt recycling crushing equipment can provide excellent mixing and crushing effects, allowing the old asphalt to be fully crushed and mixed, and increase the adjustability of asphalt without destroying the performance of the original material.

[0004] However, the asphalt regeneration and crushing equipment in the prior art, after completing the crushing of the old asphalt blocks, fails to automatically and promptly transfer the crushed materials to the conveyor belt of the new asphalt to achieve mixing of the two. Instead, the crushed materials must be manually added to the conveyor belt of the new asphalt, which makes the efficiency of the asphalt regeneration process low. Utility Model Content
