<P>PROBLEM TO BE SOLVED: To aim at the improvement of mobility of a threshing device and a combine harvester loading the threshing device, and also aim at the improvement of working efficiency of threshing work and the reduction of production cost. <P>SOLUTION: A threshing port (33) is formed at the outer sidewall (30) of a threshing chamber (22) to install a feed chain (34) for nip-conveying cereal culms along the threshing port (33), and a culm-discharging port (32) for discharging the discharged culms nip-conveyed by the feed chain (34) after threshing at the rear sidewall (25) of the threshing chamber (22) is formed by continuing to the threshing port (33) to arrange the final end part of nip conveyance of the feed chain (34) at a position in the vicinity of a rear sidewall (25) or at the position more biased in rear direction than that of the rear sidewall (25), and also a culm-discharging port (32) is opened toward the outside of the threshing device (3), thereby making a constitution that the discharged straw discharged from the culm-discharging port (32) after the threshing is released from the nip-holding of the feed chain (34) and directly discharged to the outside of the threshing device (3) from the culm-discharging port (32). <P>COPYRIGHT: (C)2013,JPO&INPIT |
