The invention discloses a separation structure. The separation structure comprises a hopper, a tray, a stirring wheel, a rotating plate, a rotating shaft and a fixed plate; the fixed plate is formed with a rotating shaft mounting hole and a first blanking hole; the rotating shaft mounting hole is rotationally connected with the rotating shaft; the rotating plate is sleeved out of the rotating shaft, and is formed with a swing arm and a second blanking hole; the swing arm is connected with a power device to drive the rotating shaft to rotate; the second blanking hole is leveled with the first blanking hole; the tray is arranged on the rotating plate, and is provided with accommodating space; a third blanking hole and a shaft through hole are formed in the bottom of the accommodating space; the third blanking hole is corresponding to the second blanking hole; the stirring wheel is positioned in the accommodating space, and is connected with the rotating shaft through the shaft through hole; and a material port is communicated with the accommodating space. The separation structure is low in noise, fast in efficiency and excellent in adaptability.
