[0025] At the same time, the second screen 13 is installed on the inner end of the installation box 1, and a guide plate 14 fixedly installed on the inner top of the installation box 1 is arranged directly below the second screen 13, a discharge port 15 is opened through the middle of the front end of the installation box 1, a positioning block 9 is fixedly installed on the inner lower end of the extension frame 8, and positioning grooves 10 compatible with the positioning block 9 are opened inside the left and right ends of the collecting basket 2, threaded holes 12 compatible with the fixing bolts 11 are opened inside the collecting basket 2 and the extension frame 8, and a discharge plate 16 located below the discharge port 15 is arranged at the front end of the installation box 1, and the combination constitutes a waste screening device for steel ball polishing.

[0026] When using the waste screening device for steel ball polishing, the specific Figure 1 and Figure 2 As shown in, first, the whole is stably placed on a designated plane through a supporting stand 7, and then the polished steel balls are poured out from the polishing drum, so that the steel balls and waste materials such as fine sand and residues fall into the collection basket 2 together. At this time, the drive motor 5 can be started, so that the drive motor 5 drives the reciprocating screw 6 to rotate in the installation box 1. At this time, the reciprocating screw 6 can be threadedly connected with the transmission block 4, so as to drive the transmission block 4 and the collection basket 2 to perform synchronous reciprocating motion, thereby facilitating the first screen 3 to perform screening work. At this time, the first screen 3 can screen out waste materials such as fine sand and residues, so that they fall onto the second screen 13, and the steel balls remain in the collection basket 2;
