step one, a motor shaft of a servo motor (13) drives a first gear (14) to synchronously rotate, the first gear (14) is meshed to drive a second gear (15), a fixed shaft (11), a driving bevel gear (34) and a polygonal shaft (12) to rotate, the polygonal shaft (12) and an inner polygonal sleeve (22) form a limiting effect, and the polygonal sleeve (22), a sieve tray (21) and a hollow ring (2) are synchronously driven to rotate along an outer ring (23);
step two, the driving bevel gear (34) is meshed to drive the driven bevel gear (33) and the linkage shaft (32) to rotate along the ear seat (31), the linkage shaft (32) drives the first chain wheel (44) to synchronously rotate, and the first chain wheel (44) sequentially drives a plurality of second chain wheels (45) and the eccentric shaft (41) to rotate through a chain belt (46);
step three, the eccentric shaft (41) drives the eccentric cam (42) to synchronously rotate, the eccentric cam (42) and the vibrating block (43) form a limiting effect, and under the matching effect of the tension spring (25), the sliding cylinder (24) is driven to slide in a reciprocating manner along the sliding rod (3), the outer ring (23) and the hollow ring (2) are driven to vibrate in a reciprocating manner up and down, and the inner polygonal sleeve (22) is synchronously driven to slide in a reciprocating manner up and down along the multi-deformation shaft (12);
step four, evenly place the trichosanthes seed in hollow ring (2) of the top, along with hollow ring (2), the rotatory in-process of sieve dish (21) is in step vibration effect that reciprocates, make large granule trichosanthes seed stay on sieve dish (21) of the top, remaining trichosanthes seed drop to hollow ring (2) of below, sieve dish (21), finally make the trichosanthes seed of different granularity size stay on different sieve dish (21), impurity in the trichosanthes seed drops to conical disk (35) via the dispersion of sieve dish (21) of the bottom, and back impurity via conical disk (35) outside landing to subaerial.
