This invention discloses a multi-stage concrete aggregate screening device, including a housing and a screening cylinder. A drive assembly is circumferentially arranged on the outer walls of the front and rear ends of the screening cylinder, allowing the screening cylinder to rotate within the housing cavity via the drive assembly. Multiple gear chambers are respectively positioned on the left and right sides of the front and rear ends of the housing, and are electrically connected to the housing cavity. Each gear chamber contains a transmission gear that is connected to the drive assembly. A cleaning chamber is also included, electrically connected and of equal length, on both sides of the housing. Each cleaning chamber contains a cleaning mechanism, which includes multiple fan plates circumferentially arranged around a drive shaft. Brush heads are located at the outer ends of the fan plates and are close to the screening cylinder. A feeding chamber has an opening at its upper end, with one side of the feeding chamber electrically connected to one end of the housing. An outlet is located at the other end of the housing. A conveying auger is horizontally positioned along the central axis of the screening cylinder, extending from one end of the feeding chamber to the outlet end.
