PURPOSE:To prevent being stopped up at the above bucket type device by connecting a hull grain spiral trough terminal end portion to a side where the buckets of a hull raising portion revolve upward and providing a raking out plate at the terminal end of the spiral trough and an opening/closing lided inclination surface inclining up toward the hull raising portion. CONSTITUTION:A mixture of classified hulled rice and unhulled rice falls into a slide-falling rice receiving trough, and is delivered to a terminal end portion by means of a slide-falling rice spiral 24. And it is raked out with a raking out plate 25 rotating in the direction of arrows, toward the oblique upper part along the inside surface of an inclination surface portion 7a. These hull grains raked out are subjected to hull raising by being received with a rising bucket 8c which has turned upward from the lower part. At this time, when lots of hull grains accumulate at a connecting portion between the slide-falling rice receiving trough 7 and a mixed rice hull raiser 8 and lots of hull grains are raked out with the raking out plate 25, an opening/closing lid 28 is pushed open and hull grains are discharged and fall down along the inclination surface 7a. Thus clogging can be prevented. |
