[0020] The device is vertically fixed with a column 6 at the inner center of the drum 4, a fixed block 7 is arranged at the top of the column 6, and a plurality of screening bars 8 are arranged between the fixed block 7 and the inner surface of the drum 4. The distance between every two adjacent screening bars 8 will gradually increase from the fixed block to the drum 4, and the plurality of screening bars 8 are all inclined. The material will move toward the inner wall of the drum 4 under the action of its own gravity. During the movement, if the diameter of the material is smaller than the distance between the two screening bars 8, it will fall into the inside of the drum 4, and the inside of the drum 4 is divided into a plurality of screening cavities by a plurality of dividing rings, thereby achieving the effect of fine screening, reducing the number of screening times, and thus improving the efficiency of the screening operation.
[0021] The first dividing ring 9 and the second dividing ring 10 are vertically fixedly connected to the bottom of the drum 4 to divide the inside into the first screening chamber 11, the second screening chamber 12 and the third screening chamber 13, which can separate the materials of different specifications after screening and prevent the materials of different specifications from being mixed together again.
[0022] The bottom ends of the first screening chamber 11 , the second screening chamber 12 and the third screening chamber 13 are respectively vertically penetrated with a plurality of first discharge holes 14 , a second discharge hole 15 and a third discharge hole 16 .
[0023] A mounting hole extending to the bottom of the rotating drum 4 is vertically opened inside the mounting seat 5, and a first motor 17 is fixedly connected inside the mounting hole.
