PROBLEM TO BE SOLVED: To improve operability of a conveyance cylinder in a grain discharge operation.SOLUTION: The combine harvester comprises: a grain storage device (1) including a thresher (18) at one side of the left/right of a machine body frame (3) having a traveling device (20), and a conveyance cylinder (6) for grain discharge at the other side of the left/right of the machine body frame (3) and a reaper (21) at the front side of the machine body frame (3). The combine harvester further comprises: an energizing device (80) that supports the base part of the conveyance cylinder (6) so as to rotationally turn to the outer lateral side of the machine body, about an axial center in the front/rear direction and energizes the conveyance cylinder (6) in a lifting/turning side and a retaining device (70) that retains the turning position of the conveyance cylinder (6). The retaining device (70) and the energizing device (80) are distributedly disposed in both front/rear sides of the conveyance cylinder (6). In a state where the conveyance cylinder (6) is stored, with it erected over the machine body frame (3), the energizing device (80) is stored within a projection range of the conveyance cylinder (6) in a machine body back view.COPYRIGHT: (C)2014,JPO&INPIT【課題】穀粒排出作業における搬送筒の操作性を高める。【解決手段】走行装置(20)を備えた機体フレーム(3)の左右一側の部位に脱穀装置(18)を設け、機体フレーム(3)の左右他側の部位には穀粒排出用の搬送筒(6)を備えた穀粒貯留装置(1)を設け、機体フレーム(3)の前側に刈取装置(21)を設けたコンバインにおいて、搬送筒(6)の基部を前後方向の軸心回りに機体外側方へ回動自在に支持すると共に、搬送筒(6)を上昇回動側に付勢する付勢装置(80)を設ける。また、搬送筒(6)の回動位置を保持する保持装置(70)を備え、保持装置(70)と付勢装置(80)を搬送筒(6)の前後両側に振り分けて配置する。また、搬送筒(6)が機体フレーム(3)上に起立して収納された状態で、付勢装置(80)が機体背面視における搬送筒(6)の投影範囲内に収まる構成とする。【選択図】 図8
