The invention relates to the field of seed drying, in particular to screening and drying apparatus for rice seeds. The screening and drying apparatus for the rice seeds comprises a support and a screening box arranged on the support. A conveying device is arranged on the support. A water conveying device for screening and washing the seeds is also arranged on the support. A screening device is arranged on the screening box. An opening-and-closing device is arranged at the bottom of the screening box, wherein the opening-and-closing device is used for allowing the seeds screened to fall. A drying device is arranged at a lower end of the screening box, wherein the drying device is used for drying the seeds washed. A draining device for draining water is arranged inside the screening box. According to the screening and drying apparatus for the rice seeds, the rice seeds are screened and washed in a large scale; compared with traditional manual screening and washing, the screening cardinalnumber is large; washing efficiency is high; production efficiency is improved; the cost is lowered; and one end of a water conveying pipe is arranged to be a shape with certain radian, influence anddamage caused to the rice seeds due to drainage can be reduced, and screening efficiency and washing efficiency are guaranteed.
