(G) Effect of the invention As described above, the invention has a detaching section, a wind-selecting section, and a plurality of sorting discs having a plurality of potholes formed on the side surface thereof, which are mounted at intervals on the rotary shaft that laterally bridges them. Then, insert the brown rice gutter into the side of the downward rotation of the sorting disc and install the slanted disc type sorting part for sorting the mixed rice of brown rice and paddy and the prime mover that drives these parts via belts. In the disc-type sorting hulling machine to be configured, a belt clutch is interposed in the belt, and the first operation of the clutch lever of the belt clutch starts the removing section and the wind selecting section, and the second operation causes the disc-type selecting section to operate. Since it is configured with a stepwise driving means for starting, a sudden load is applied to the prime mover like the conventional one that starts all parts at once through the belt, and the grain clogging phenomenon due to the decrease in horsepower occurs. Not even In the case of a type that selects mixed rice of brown rice and paddy by the type selection unit, if the grain remains in the disc type selection unit, the selection disc will start more and more due to the resistance of the mixed rice. Although difficult, it is possible to avoid a sudden load at the time of starting because the driving to each part is made to be performed step by step, and it is possible to perform a smooth starting, thereby preventing the grain clogging phenomenon.
