[0040] Working principle:

[0041] S1. Start the first motor 201 to drive the ramp 202 to rotate. The rotation of the ramp 202 can enable the sliding rod 203 to slide in the slide groove 204. The inclined arrangement of the ramp 202 can drive the sliding rod 203 to slide up and down, and the sliding rod 203 drives the support platform 205 to reciprocate up and down; the rotation of the connecting shaft drives the rotation of the synchronous belt 301, and the synchronous belt 301 drives the screw rod 302 to rotate. The screw rod 302 cooperates with the movable seat 303 to enable the movable seat 303 to reciprocate up and down on the screw rod 302, thereby enabling the connecting plate 304 to reciprocate up and down;

[0042] S2. When the support platform 205 is at the lowest end, the sealing cover 502 is at the cleaning rack 402 and the cleaning nozzle 403. The water pump is started, and water flows through the cleaning rack 402 and finally through the cleaning nozzle 403 to clean the sealing cover 502.

[0043] S3. When the first motor 201 is started so that the support platform 205 is at the highest point, the connecting plate 304 drives the sealing cover 502 to seal the screening frame 604 and the limit frame 605. The second motor 602 is started to drive the screening frame 604 to rotate. The screening frame 604 can screen out impurities or unqualified strains and collect them through the slag collection basket 603. Pulling the handle 606 facilitates the disassembly of the slag collection basket 603 and the limit frame 605, and the impurities are centrally processed. The high-throughput screening method can quickly process a large number of samples and significantly improve the screening efficiency; the automated sealing and cleaning mechanism 400 can reduce pollution and improve the accuracy of the screening results; the automated system reduces manual operation and reduces labor intensity.
