Screening and separating device for saline-alkaline tolerant bacterial colonies

The saline-alkaline tolerant bacterial colony screening and separating device comprises a sorting bin, and a plurality of primary disinfection mechanisms and secondary disinfection mechanisms are mounted on mounting seats on the left inner side wall and the right inner side wall of the sorting bin correspondingly; and the two conveying units are both arranged at the bottom of the sorting bin, and a plurality of vessel mounting discs which are distributed at equal intervals are fixed to a conveying belt of each conveying unit. According to the device, when the high-resolution probe recognizes qualified bacterial colonies, a coil of the electromagnet loses power, the metal block drives the selection needle to extend outwards and perform bacterial colony selection operation, and when the high-resolution probe does not recognize qualified bacterial colonies, the coil of the electromagnet is electrified, and the selection needle is kept to return back into the sliding cylinder; therefore, the high-throughput bacte
