The rear end of the threshing drum (7a) is projected backward from the rear end of a threshing net (7c), and the rear end side of a threshing drum shaft (7) supporting the threshing drum (7a) is journaled to a threshing chamber rear plate (6b). The front side of a threshing chamber internal rear plate (6d) provided at a rear part in the threshing chamber (6) is formed with a supply port (6e) for supplying threshed discharge dust in the threshing chamber (6) to the dust discharging chamber (10), and a free grain over rack collecting part (B) narrower in longitudinal width than the supply port (6e) is formed between the threshing chamber rear plate (6b) and the threshing chamber internal rear plate (6d). A plate-like member (9a) for partitioning the threshing chamber (7a) from the dust discharging drum (11a) is provided in the free grain over rack collecting part (B). <P>COPYRIGHT: (C)2012,JPO&INPIT |
