Patent abstract
In a rice huller, a first small-diameter pulley and a second large-diameter pulley are attached to a first roll shaft. A first large-diameter pulley and a second small-diameter pulley are attached to a second roll shaft. This configuration makes it possible to switch between a first driving state in which a rice hulling operation is performed by passing and driving a belt between the first small-diameter pulley on the first roll shaft and the first large-diameter pulley on the second roll shaft and a second driving state in which a rice hulling operation is performed by passing and driving a belt between the second large-diameter pulley on the first roll shaft and the second small-diameter pulley on the second roll shaft.
