た。The rear portion of the scraping belt in the known harvester rotates away from the scraping path while rotating along the outer periphery of the pulley around which the belt is wound, and is protruded therefrom. The large number of flexible lugs also turn rapidly while rotating integrally with the scraping belt and withdraw from the scraping path. At this time, the flexible lugs are deflected because they rotate backward while pushing the grain stalk during pushing and conveying, and when they reach the end of the scraping, they are rapidly extended and swivel, so that the caught grain stalk is scraped. Since the bobbin jumped out of the feeding route, there was a problem that the grain stalk was disturbed in the scraping posture and wrapped around the pulley.
