The invention discloses an environment-friendly construction waste sieving cylinder comprising a bracket, a cylinder body and a rotating rod. The cylinder body is fixed to the upper end of the bracket, a mounting seat arranged at the upper end of the bracket is located on one side of the cylinder body, a motor is fixed to the upper end of the mounting seat through a damping cushion, an output shaft at one end of the motor is in engaged connection with one end of the rotating rod, the rotating rod is arranged on the inner side of the cylinder body, and the other end of the rotating rod is fixedto the inner wall of the cylinder body; and meanwhile, a first sieving plate and a second sieving plate are sequentially fixed to the outer wall of the rotating rod through first bearings correspondingly, and the outer walls of the first sieving plate and the second sieving plate are simultaneously and fixedly connected with the inner wall of the cylinder body. According to the environment-friendly construction waste sieving cylinder, by arranging the first bearings, silencers, the damping cushion, a silencing cotton plate, a protecting shell, the rotating rod, the first sieving plate, crushing blades and the second sieving plate, the problems that a construction waste sieving cylinder at the present stage is not good enough in sieving effect and low in environmental protection are solved.
