<P>PROBLEM TO BE SOLVED: To reduce the forth loss in a threshing device, and to reduce the loss at the outside of the machine. <P>SOLUTION: The threshing device includes: a threshing chamber (15) in which a threshing cylinder (18) having multiple threshing teeth (19) are rotatably supported; and a dust exhausting chamber (17), in which a threshing opening (21) is opened at a lateral side of the threshing chamber (15). A free grain collection chamber (56) for collecting free grains with the threshing teeth (19) at the rear end of the threshing cylinder (18) is formed at a rear side portion rather than a communication port (23) for communicating the threshing chamber (15) with the dust exhausting chamber (17). A partition plate (55) for partitioning the threshing chamber (15) and the free grain collection chamber (56) is provided at an upper portion of the threshing chamber (18), and a first blade (50) facing to a rotation trajectory of the threshing teeth (19) is provided at the upper side portion of the threshing opening (21). <P>COPYRIGHT: (C)2013,JPO&INPIT |
