Because of the self characteristics of the Qinghai salt lake, the salt is directly extracted by a loader or an excavator in the prior art, and the defects of low salt extraction efficiency, high oil consumption and high cost and inconvenient salt extraction operation at a place with a slightly large water depth are overcome. Therefore, some salt mining ships are invented, a cutter head mechanism for salt mining is arranged at the bow of each salt mining ship, salt ores are collected through rolling of the cutter head mechanism, and the salt mining speed can be greatly improved.
