Several grading and screening devices 2 are connected sequentially from top to bottom. The feeding hopper 1 is connected to one end of the sequentially connected grading and screening devices 2 and the other end is connected to the stabilizing ring 5. The stabilizing ring 5 is connected to the swing plate 6 via the connecting frame 10. The swing plate 6 is connected to the fixed frame 8 via the screening power device. The cylinder 3 is connected to... The piston rod is connected to one end of the lifting rod 4 on the connecting frame 10. The other end of the lifting rod 4 passes through several grading and screening devices 2 and is connected to them in a transmission manner. The grading and screening device 2 includes a screening ring 21, a screening port 22, a distance fixing device 23, a feeding plate 24, a conical sliding ring 25, a connecting rod 26, a guide hopper 27, and a discharge pipe 28. Several screening ports 22 are opened on one end of the screening ring 21. The conical sliding ring 25 is connected to one end of the screening ring 21 near the screening port 22. The conical sliding ring 25 is connected to several connecting rods. 26 is connected to the inner wall of the screening ring 21 of the adjacent grading and screening device 2 below. The guide hopper 27 is connected to the conical sliding ring 25. One end of the discharge pipe 28 is connected to the guide hopper 27.
