[0028] A plurality of partition plates 13 are installed inside the discharge seat 3 , and a plurality of discharge grooves 14 are installed through the side wall of the discharge seat 3 . The discharge grooves 14 are located between two adjacent groups of partition plates 13 .

[0029] Through the above structure, the copper ball material is sent to the discharge channel 8 through the feed trough 7, and the copper ball is sent to the bottom of the screening box 1 through the discharge channel 8 to prevent the copper ball material from splashing at the bottom of the screening box 1. The discharge channel 8 sends the copper ball material to the top of the screening hole 4 with a smaller aperture at the bottom of the screening box 1, and the small copper balls are screened out through the small screening holes 4. The apertures of the screening holes 4 at the bottom of the screening box 1 are arranged from small to large. The rotating shaft 11 drives the insert cylinder 5 to rotate, and the insert cylinder 5 drives the material stripping plate 6 to rotate. The copper balls are moved toward the screening holes 4 with larger apertures through the material stripping plate 6, and copper balls of different sizes are screened out through the appropriate screening holes 4. The copper balls screened out through the screening holes 4 fall into the inside of the discharge seat 3, are classified by multiple groups of partitions 13, and are discharged and collected through the discharge trough 14. The specific structure is as follows:
