PROBLEM TO BE SOLVED: To provide a combine harvester for discharging grains in a grain tank via a flexible discharge cylinder by an air transportation, wherein the grain discharge port of a discharge cylinder is longitudinally adjusted to enhance the degree of freedom of loading of a transport vehicle.SOLUTION: A flexible starting end side discharge cylinder (48a) is supported by a longitudinal support cylinder (45) raised from the rear part of an undercarriage (1) and a support member (46) connecting the base portion vertically rotatably to the upper portion of the longitudinal support cylinder (45). Inside of the support member (46), there is arranged a clamp (49) for connecting a terminal end side discharge cylinder (48b) communicating with the end side discharge cylinder (48a)to the tip of the support member (46), and for holding the connected state between the starting end side discharge cylinder (48a) and the terminal end side discharge cylinder (48b).SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】グレンタンク内の穀粒を可撓性の排出筒により空気搬送で排出するコンバインにおいて、排出筒の穀粒排出口を前後に調節し、運搬車への積み込みの自由度を高める。【解決手段】可撓性の始端側排出筒(48a)を、前記車台(1)の後部に立ち上げた縦支持筒(45)と該縦支持筒(45)の上部に基部を上下回動自在に連結している支持部材(46)で支持し、該支持部材(46)の先端部に前記始端側排出筒(48a)と連通させた終端側排出筒(48b)を連結し、始端側排出筒(48a)と終端側排出筒(48b)の接続状態を保持するクランプ(49)を、前記支持部材(46)の内部に配置する。【選択図】図6
