<P>PROBLEM TO BE SOLVED: To provide a thresher which can adjust a processed product-sending speed at each position in a threshing chamber in response to a state, can adjust to the sending speed responding to the state, and can easily set an urging force to each dust-sending guide. <P>SOLUTION: The thresher in which a plurality of dust-sending guides 24 supported on a ceiling plate 22 side and used for contacting with processed products in a threshing chamber 14 to adjust a sending speed for the processed products are disposed; resilient members 33 for urging the dust-sending guides 24 to initial rotation positions and operation devices 36 for changing the initial rotation positions are disposed; and the dust-sending guides 24 are rotated against the urging forces of the resilient members 33, when receiving loads from the processed products, is characterized in that the operation devices 36 are disposed in the same number as that of the dust-sending guides 24 so that the initial rotation positions of the dust-sending guides 24 can separately be changed, respectively, and the resilient members 33 are disposed on each dust-sending guide 24 side, so that the dust-sending guides 24 are rotated on escape sides in response to the loads, when the dust-sending guide 24 receive predetermined or larger loads. <P>COPYRIGHT: (C)2012,JPO&INPIT |
