The specific implementation mode is as follows: with reference to fig. 1-2, a screening apparatus dedicated for workpieces comprises a conveying mechanism, a screening mechanism 1 and a sorting mechanism, and is characterized in that: the conveying mechanism comprises two V-shaped belt wheels 5 which are axially arranged in parallel, and the belt wheels 5 are connected through a conveying belt 4 with a V-shaped section; the feed inlet 101 of the screening mechanism 1 is in a horn mouth shape and is positioned at the tail end of the conveying mechanism, the lower end of the feed inlet 101 is provided with a first-level screening hole 102, a second-level screening hole 103 and a third-level screening hole 104 are arranged below the feed inlet 101, the diameter of the first-level screening hole 102 is equal to the designed maximum diameter size, the diameter of the second-level screening hole 103 is equal to the designed standard diameter size, and the diameter of the third-level screening hole 104 is equal to the designed minimum diameter size. A first photosensor 105 and a second photosensor 106 are mounted on the side walls of the primary screening hole 102 and the secondary screening hole 103, respectively. The screening mechanism comprises a screening mechanism 1 and is characterized in that a spring 3 is sleeved on the outer side of the screening mechanism 1, the upper end of the spring 3 is the outer edge of a feeding hole 101, the lower end of the spring 3 is connected with a rack, the spring 3 supports the whole screening mechanism 1, and a vibrator 2 is arranged on the outer wall of the screening mechanism 1. The sorting mechanism is positioned on the upper part of the screening mechanism 1 and comprises a guide rail 9, an electric slide block 8, a conveying rope 7 and an electromagnet 6.
