Grain seed soaking device

The invention discloses a cereal seed soaking device, relates to the field of seed soaking devices, and solves the problem that when an existing cereal seed soaking device is used, it is difficult to uniformly separate seeds and improve the operation efficiency at the same time. The cereal seed soaking device comprises a base, a dispersion mechanism, an output mechanism and an oxygenation mechanism; the dispersing mechanism comprises a rotating pipe, a first separating net and a second separating net, dispersing cavities are formed between the first separating net and the second separating net, and the output mechanism comprises a collecting barrel. Seeds can be input into different dispersing cavities through a single pipeline to be dispersed and stored, meanwhile, the rotating pipe is filled with oxygen in cooperation with the oxygen filling mechanism, seed soaking operation is assisted, and after soaking is completed, the seeds in the dispersing cavities are directly conveyed into the collecting barrel thr
