PROBLEM TO BE SOLVED: To compactly constitute a grain culm-conveying part of a pre-treating part capable of reaping unreaped grain culms of seven rows.SOLUTION: Right and left plant-root conveyors 38A and 38D for receiving the grain culms from plant-root-raking devices 27A and 27D for each two rows at the right and left both sides constituting the grain culm-conveying part 6 of the pre-treating part 3 respectively, and conveying them to a confluent part M at the rear side, and two plant-root sub-conveyors 38B and 38C for receiving the grain culms from plant-root-raking devices 27B and 27C for two rows at one side and for one remaining row in the three rows at the center side respectively and separately joining to one of the right and left main plant-root conveyors 38A and 38D are installed. Each star wheel 31 of plant-root-raking devices 27 corresponding to reaping parts C1 to C5 for five rows counted from the right based on the progressing direction of a traveling machine body 2 is subjected to meshed transmission.COPYRIGHT: (C)2009,JPO&INPIT【課題】7条分の未刈り穀稈を刈り取り可能な前処理部の穀稈搬送部をコンパクトに構成する。【解決手段】前処理部3の穀稈搬送部6を構成する左右両側2条分の株元掻込装置27A,27Dから、それぞれ穀稈を受け継いで後方の合流部Mに搬送する左右の主株元搬送体38A,38Dと、中央側3条分のうち片側2条分と残り1条分の株元掻込装置27B,27Cからそれぞれ穀稈を受け継いで、前記左右の主株元搬送体38A,38Dの何れかに各別に合流する2つの副株元搬送体38B,38Cを設けると共に、走行機体2の前進方向に対して右から数えて5条分の刈取部C1~C5に対応する株元掻込装置27の各スターホイール31を噛合い伝動させた。【選択図】図4
