PROBLEM TO BE SOLVED: To provide the threshing structure of a whole culm-charging type combined harvester which can improve a threshing performance and grain recovery efficiency.SOLUTION: A threshing cylinder 16 comprises a plurality of threshing cylinder frames 47 disposed in a state that the frames 47 are arranged in the circumferential direction of the threshing cylinder 16 at a prescribed distance, and a plurality of threshing teeth 48 disposed so as to project from the threshing cylinder frames 47 to the outside of the threshing cylinder 16, thus forming an inner space S communicating with a threshing chamber 14 in the threshing cylinder 16. A support plate 45 for closing the upward side portion of the inner space S from the rear side is disposed in the longitudinally middle portion of a support shaft 15 to stop the flowing of treated materials toward the downward side of the threshing treatment in the inner space S.COPYRIGHT: (C)2010,JPO&INPIT【課題】脱穀性能や穀粒回収効率の向上を図ることができる全稈投入型コンバインの脱穀構造を提供する。【解決手段】扱胴16を、扱胴16の周方向に所定間隔を隔てて並ぶ状態に配備した複数の扱胴フレーム47と、扱胴フレーム47から扱胴16の外方に向けて突出するように装備した複数の扱歯48とから構成して、扱胴16の内部に扱室14に連通する内部空間Sを形成する。内部空間Sの上手側部分を後側から塞ぐ支持プレート45を支軸15の前後中間部に装備し、内部空間Sでの処理物の脱穀処理方向下手側への流動を阻止する。【選択図】図3
