PROBLEM TO BE SOLVED: To provide a grain culm reaping device of a combine in which a loss due to an unreaped portion is not caused, a harvested material is not damaged and soil is not deposited.SOLUTION: A grain culm reaping device of a combine has a frame unit (6) attached to the front of the combine, a pair of left and right reaping units (1) attached to the frame unit (6) and each comprising a cutting blade (1A), and a conveyance unit (5) arranged between the pair of left and right reaping units (1) and conveying the grain culm being cut by the cutting blade (1A) backward. The conveyance unit (5) has multiple vertical rotation-type endless conveying members with protrusions (5A, 5B, 5C, 5D, 5E) laterally juxtaposed in a backward-climbing/tilting manner, respectively. The front end of the endless conveying member (5C) positioned at a central portion in the lateral direction is positioned forward more than the front end of the endless conveying members (5A, 5B, 5D, 5E) positioned at both side portions.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】コンバインの穀桿刈取装置において、刈り残しによる損失を生じず、収穫物を傷付けずかつ土を付着させないこと。【解決手段】コンバインの前部に取り付けられるフレーム部（６）と、前記フレーム部（６）に取り付けられかつ各々が刈刃（１Ａ）を具備する左右一対の刈取部（１）と、左右一対の前記刈取部（１）の間に配置され前記刈刃（１Ａ）により切断された穀桿を後方に搬送する搬送部（５）と、を有するコンバインの穀桿刈取装置であって、前記搬送部（５）が、それぞれ後方登り傾斜して左右方向に並設された複数の縦回し型の突起付き無端搬送部材（５Ａ、５Ｂ、５Ｃ、５Ｄ、５Ｅ）を有し、左右方向の中央部分に位置する無端搬送部材（５Ｃ）の前端が、両側部分に位置する無端搬送部材（５Ａ、５Ｂ、５Ｄ、５Ｅ）の前端よりも前方に位置する。【選択図】図１
