The invention discloses a concrete recycled aggregate screening impurity-removing device. The concrete recycled aggregate screening impurity-removing device comprises a main body; a first screen and asecond screen are obliquely installed in an inner cavity of the main body in a sliding mode; a feeding inlet is formed in one side of the top end of the main body; a screening motor is fixedly installed on the outer side wall of the main body and rotationally connected with a driving wheel which is connected with a driven wheel through a transmission belt; a first sliding block is fixedly installed on a frame of the first screen; a second sliding block is fixedly installed on a frame of the second screen; a first connecting rod is arranged between the driven wheel and the first sliding block;and a second sliding rod is arranged between the second sliding block and the driven wheel. The concrete recycled aggregate screening impurity-removing device is simple in structure, ingenious in conception, capable of performing multi-stage screening on recycled aggregate and high in practicability.
