When the seeds are between the first screen 8 and the second screen 27, the seeds are subjected to secondary dust removal by the suction fan 18 at the bottom, and the sewage in the two collecting boxes 10 is discharged through the sewage pipe 17, and then the seeds fall onto the second screen 27, so that the seeds are separated from the heavier small particles of dust, and the heavier small particles of dust are discharged out of the drying box 1 and the seeds are discharged from the discharge port.
[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
