<p><P>PROBLEM TO BE SOLVED: To quickly deal with a change of the amount of treated materials at a separation part and to perform control and control release of discharge dust in spite of being a combine harvester using threshed waste straws discharged from a threshing room as a detection object and performing control and control release of discharge dust in a discharge dust path. <P>SOLUTION: A discharge dust control body 50 for opening and closing a discharge dust path 22 and a transfer detection body 51 having a contact action on threshed waste straws at the start part of the conveying path of a waste straw conveying device 40 in order to detect a waste straw transfer from a threshing feed chain 12 of the waste straw conveying device 40 are arranged. A connection means for connecting the transfer detection body 51 to the discharge dust control body 50 is arranged so that the discharge dust control body 50 is changed to an open position when the transfer detection body 51 is in a detection state and the discharge dust control body 50 is changed to a closed position when the transfer detection body 51 is in a non-detection state. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
