Sand screening equipment for green building engineering

The utility model provides sand screening equipment for green constructional engineering, and relates to the field of sand screening of the green constructional engineering. The sand screening equipment for the green building engineering comprises a shell, the lower end of the shell is fixedly connected with a screening net A, the right end of the shell is rotationally connected with an output shaft, the right end of the output shaft is fixedly connected with a belt pulley A, the lower end of the belt pulley A is meshed with a belt, and the end, away from the belt pulley A, of the belt is meshed with a belt pulley B. When the sand screening equipment for the green building engineering is used, a double-shaft motor drives a belt wheel B to rotate, the belt wheel B drives a belt to rotate, the belt drives a belt wheel A to rotate, the belt wheel A drives an output shaft to rotate, the output shaft drives a disc to rotate, the disc drives a connecting block to rotate, the connecting block drives a moving plate t
