It is formed in the shape of a semi-arc-shaped rain gutter, and the clogging phenomenon of rice husks is suppressed compared to the tubular one. An introduction guide slope that can be dropped and fed, and that the rice husks that fall from the feed path member collide with each other and can introduce the rice husks into the penetration trace groove and the vertical entrance path is formed. Since the rice husk introduction guide member is provided, the rice husks falling from the feed path member can be reliably introduced and dropped into the penetration trace groove and the vertical mouth passage by the rice husk introduction guide member.
