[0030] Working principle: the external frame 1 is driven by the conveying crawlers 3 on both sides to move to the discharge port position at the lower end of the standard parts conveyor, and then the standard parts are unloaded and introduced into the upper end opening of the external frame 1, and then fall into the split screening box 4 on the uppermost layer, and the split screening box 4 is translated and vibrated by the multi-layer support frame assembly 2 to accelerate the rapid downward separation of the standard parts, and then the single-layer split screening box 4 is filled to a certain value, and the vibration amplitude will gradually decrease, and finally the external frame 1 is translated to the layered frame position by the conveying crawlers 3 on both sides, and then the electrically controlled flip-type closing cover 5 is flipped to open the lateral separation port, and the filled split screening box 4 is introduced into the layered frame, and then the conveying crawlers 3 on both sides drive the external frame 1 to translate to the loading frame, and then the split screening box 4 on the loading frame is introduced into the multi-layer support frame assembly 2, and finally the external frame 1 is translated back to the discharge port position at the lower end of the standard parts conveyor by the conveying crawlers 3 on both sides.

[0031] In order to cooperate with support and adjustment, the multi-layer support frame assembly 2 includes a first support frame 21, a second support frame 22, a third support frame 23, and a linkage reciprocating control module installed at the positions of the first support frame 21, the second support frame 22 and the third support frame 23.

[0037] The top driving motor 7 drives the driving gear 8 through the output shaft, and drives the lateral eccentric gear 9 to rotate synchronously, and then uses the eccentric shaft 10 at the lower end of the lateral eccentric gear 9 to drive the control connecting rod 11, and uses the control connecting rod 11 to control the elastic extrusion control rod 12 to slide and adjust inside the side guide through hole, and uses the elastic extrusion control rod 12 to extrude the three surfaces of the split screening box 4. By reciprocatingly squeezing the three surfaces of the split screening box 4, the split screening box 4 is controlled to vibrate and translate, thereby accelerating the screening efficiency of the standard parts.

[0038] In order to cooperate with the elastic extrusion reset, the inner closing frame 24 is elastically equipped with an embedded reset spring block 26 .

[0039] A lateral assembly groove with a built-in guide strip is provided on the inner closing frame 24.
