The invention discloses a roller type vibration double sieve. The roller type vibration double sieve comprises a primary screening mechanism and a secondary screening mechanism in sequence along a material conveying direction, wherein the primary screening mechanism comprises a primary floating carrier roller seat, a primary spring seat and a primary vibration roller sieve; the secondary screening mechanism comprises a secondary floating carrier roller seat, a secondary spring seat and a secondary vibration roller sieve; a discharging hole end of the primary vibration roller sieve stretches into the secondary vibration roller sieve; vibration supporting rolling wheels are arranged in the peripheral direction of the outer wall of the discharging hole end of the primary vibration roller sieve at interval; a feeding hole end of the secondary vibration roller sieve is overlapped on the vibration supporting rolling wheels. The roller type vibration double sieve is convenient to detach and mount and has good screening effect; the screening rate is greatly improved, the automation degree of the working is high, the labor intensity of workers is small and the production efficiency is high; the roller type vibration double sieve is suitable for back-grade sorting of an urban and rural household garbage treatment system, can be used for selecting plastic, textiles and screening sand stones, glass, metal and the like, and provides guarantees to the secondary utilization of materials.
