The utility model discloses an automatic sieving system for non-uniform model sand. The system comprises an automatic sieving machine (1) and a belt conveyor, wherein the automatic sieving machine (1) comprises a sieve body (11), a dual-vibrating motor (12) and a base (13); a feeding port (111) and a discharging port (112) are formed in two ends of the sieve body (11) respectively; the sieve body (11) is connected with the dual-vibrating motor (12) through a force transmission plate (14), and the dual-vibrating motor (12) has an inclined angle in the perpendicular direction relative to a sieving surface; the sieve body (11) and the base (13) are connected through support springs (15), and the support springs are nested on spring retainers located at the bottom of the sieve body and the spring retainers located at the top of the base; a conveying port of the belt conveyor is formed above the feeding port (111) of the sieve body. The automatic sieving system can sieve used model sand and reuse the model sand, so that the cost is reduced.
