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. The threshing frames 47 comprise round pipes or round steel rods.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。複数の扱胴フレーム47を丸パイプ材又は丸棒鋼材で構成する。【選択図】図3
