Crushing device for recycling waste asphalt

The invention relates to the field of waste asphalt recovery crushing equipment, in particular to a waste asphalt recovery crushing device which comprises a shell frame, a cover plate is arranged at the top end of the shell frame, an eccentric rolling crushing mechanism is arranged on one side of the cover plate, a vibration mechanism is arranged below the eccentric rolling crushing mechanism, and the lower end of the vibration mechanism abuts against a hole screen mechanism. A multifunctional transmission mechanism is arranged below the hole screen mechanism, one side of the multifunctional transmission mechanism is connected with a screw conveying mechanism, and a collecting box is arranged below the multifunctional transmission mechanism. In the process that the waste asphalt is crushed by the eccentric rolling crushing mechanism, generated dust substances can be subjected to physical dust fall by the cleaning spray head, and the whole device is subjected to sealing treatment, so that the harm to the envir
