PROBLEM TO BE SOLVED: To enable the posture of a waste straw-conveying mechanism 62 to be switched between a conveying posture and a clogging-removing posture by a simple operation in a combine harvester.SOLUTION: The combine harvester includes the waste straw-conveying mechanism 62 for conveying the waste straw after threshing, a waste straw-nipping body 603 for nipping the waste straw by facing the waste straw-conveying mechanism 62, a waste straw cutter 63 for cutting the waste straw, and a waste straw-switching plate 650 for opening or closing a waste straw-conveying passage 648 directed to the waste straw cutter 63. The waste straw-conveying mechanism 62 is constituted so that the posture can be switched between the conveying posture facing the waste straw-nipping body 603, and the clogging-removing posture apart from the waste straw-nipping body 603. A switching operation tool 626 for carrying out the posture-switching operation of the waste straw-conveying mechanism 62 is installed in the waste straw-conveying mechanism 62 so as to be operated from the rear side of the waste straw-conveying mechanism 62. The waste straw-switching plate 650 is formed into a shape extended to the switching operation tool 626 in the opened state of the waste straw-conveying passage 648 in the side view.COPYRIGHT: (C)2012,JPO&INPIT【課題】コンバインにおいて、排藁搬送機構62を簡単な操作で搬送姿勢と詰り解除姿勢とに姿勢変更できるようにする。【解決手段】本願発明のコンバインは、脱穀後の排藁を搬送する排藁搬送機構62と、前記排藁搬送機構62に対峙して前記排藁を挟持するための排藁挟持体603と、前記排藁を切断する排藁カッタ63と、前記排藁カッタ63に向かう排藁搬送通路648を開閉する排藁切換板650とを備える。前記排藁搬送機構62は、前記排藁挟持体603に対峙する搬送姿勢と、前記排藁挟持体603から離れる詰り解除姿勢とに姿勢変更可能に構成する。前記排藁搬送機構62には、前記排藁搬送機構62を姿勢変更操作する切換操作具626を、前記排藁搬送機構62の後方側から操作し得るように設ける。前記排藁切換板650は、側面視において、前記排藁搬送通路648を開放した状態で前記切換操作具626に向けて延びる形状に形成する。【選択図】図5
