The top of the base 1 is connected to the screening drum 2, the screen 3 is divided into several groups and is evenly installed in the screening drum 2 from top to bottom, the feed pipe 4 is located at the top of the screening drum 2, the discharge pipe 5 is divided into several groups and is evenly installed on one side of the screening drum 2, the ultrasonic generator 6 is connected to the transducer 7 through a line, the transducer 7 is installed in the screening drum 2, several groups of discharge pipes 5 are staggered left and right, a floating secondary sorting component 8 is installed between two adjacent groups of discharge pipes 5, a guide groove 9 is opened at the bottom of the upper discharge pipe 5, and a guide groove 9 is opened at the lower discharge pipe 5. A slide groove 10 is provided on the upper surface of the square discharge pipe 5, and a floating secondary sorting component 8 is installed between the guide groove 9 and the slide groove 10. The floating secondary sorting component 8 includes a screening plate 11, a guide plate 12, a driver 13, a reset spring 14 and a column 15. The screening plate 11 is movably inserted into the guide groove 9 and a plurality of screening holes 16 are evenly provided on the surface. The upper end of the guide plate 12 is connected to the bottom of the screening plate 11 and the lower end is movably arranged in the slide groove 10. Two groups of rubber sealing strips 17 are symmetrically arranged at both ends of the slide groove 10, and the inner ends of the two groups of rubber sealing strips 17 are connected to the two sides of the guide plate 12. The driver 13 is located on the left side of the guide plate 12, and the left end of the reset spring 14 is connected to the guide plate 12 and the right end is connected to the column 15.

[0019] Further improvement, such as Figure 2 As shown: the length of the screening plate 11 is greater than the length of the guide groove 9, and the width of the screening plate 11 is greater than the width of the guide groove 9. This design ensures that the screening plate 11 can always perform a blocking screening process on the guide groove 9 to avoid material leakage.

[0020] Further improvement, such as Figure 3 As shown, several groups of screening holes 16 are arranged in several rows, and the lower ends of the screening holes 16 are connected to the inner cavity of the guide plate 12 for secondary screening of the screened materials.

[0023] During use: the utility model discharges the material screened by the screen 3 through the discharge pipe 5. After the material enters the discharge pipe 5, the motor 18 drives the rotating wheel 19 to rotate. During the rotation, the rotating wheel 19 uses the shifting blade 20 to intermittently act on the guide plate 12, so that the guide plate 12 and the top screening plate 11 move to the left and the guide plate 12 is reset to the right by the reset spring 14, thereby achieving the purpose of swing screening, and the screening holes 16 on the top screening plate 11 are used to perform secondary screening on the passed material, and the material with smaller particles is introduced into the discharge pipe 5 below, so as to improve the degree of refinement of the screening and reduce the situation where the material is directly vibrated and discharged from the outlet without sufficient screening, resulting in a large amount of unqualified material mixed in the upper screened material.
