The invention provides a paddy husking separator capable of separating and discharging foreign bodies mixed in mixed rice through a simple structure without causing loss of the mixed rice. The paddy husking separator provided by the invention is provided with a paddy husking device (2) and a multi-layer swing separating board (11). The multi-layer swing separating board (11) is used for separating mixed rice composed of paddy and unpolished rice processed by the paddy husking device. The paddy husking separator is characterized in that the paddy husking separator is provided with a mixed rice delivering board (12a) used for supplying the mixed rice to different layers of the multi-layer swing separating board (11); a multi-hole board (71) of a receiving part used for allowing the mixed rice to drip to the mixed rice delivering board (12a) and transporting long-strip-shaped foreign bodies; and a multi-hole board (73) of a separating part allowing the mixed rice that does not drip to the multi-hole board (71) of the receiving part but is discharged along with the long-strip-shaped foreign bodies to drip to the top layer of the swing separating board (11).
