PROBLEM TO BE SOLVED: To enable a sieve to be maintained easily without disassembling a swinging selection shelf.SOLUTION: The combine harvester is constituted as follows. The sieve 23 is installed so as to be disassembled to the upper part of the swinging selection shelf 20 and so as to be assembled from the upper part of the swinging selection shelf 20, and a feed chain part 9 equipped with a feed chain 13B is constituted so as to be freely opened and closed between a closed position for nipping and conveying grain culms between the feed chain and a nipping rod, and an opened position exposing the side part of a threshing chamber positioned at the far side. A checking opening 11S allowing the disassembled sieve 23 to be passed is formed within the range including the far side of the feed chain part 9 at the side part of the threshing chamber 11, and a lid body 11Z for opening and closing the checking opening 11S is installed.COPYRIGHT: (C)2012,JPO&INPIT【課題】揺動選別棚を取り外すことなく容易にシーブをメンテナンスできるようにする。【解決手段】上記課題は、シーブ23を、揺動選別棚20の上方への取り外し及び前記揺動選別棚20の上方からの取り付けが可能なように設け、フィードチェーン13Bを備えたフィードチェーン部9を、フィードチェーンと挟持杆との間で穀稈を挟持搬送する閉位置と、裏側に位置する扱室の側部が露出する開位置とに開閉自在な構成とし、扱室11の側部におけるフィードチェーン部9の裏側を含む範囲に、取り外したシーブ23が通過可能な点検口11Sを設けるとともに、この点検口11Sを開閉する蓋体11Zを設けたことを特徴とするコンバインにより解決される。【選択図】図14
