PROBLEM TO BE SOLVED: To provide a combine harvester wherein in the radio operation device of a grain-unloading auger in the combine harvester, radio communication between a receiving antenna on the machine frame side and a radio auger operation device held by a worker is well performed without needing to consider that a wiring between the receiving antenna and a control device is twisted, and without hindering the revolution movements of the unloading auger with the receiving antenna.SOLUTION: In the combine harvester directing the unloading auger (5) supported at the upper end of a grain-lifting cylinder (24) vertically disposed on the rear portion of the machine frame to make the revolution and lifting or lowering operations with a radio auger operation device (11), an antenna (23) for receiving a command radio wave from the radio auger operation device (11) and an auger control box (26) for outputting a control signal on the basis of the command radio wave are attached to the rear side portion of the machine frame behind the grain-lifting cylinder (24).COPYRIGHT: (C)2012,JPO&INPIT【課題】コンバインにおける穀類排出オーガの無線操作装置において、受信アンテナと制御装置との配線が捩じられることを考慮する必要が無く、受信アンテナが排出オーガの旋回動作に邪魔にならず、機体側の受信アンテナと作業者が持っている無線オーガ操作器との無線通信が良好に行えるようにする。【解決手段】機体後部に立設した揚穀筒(24)の上端に支持した排出オーガ(5)を無線オーガ操作器(11)で旋回及び昇降の動作指示を可能にしたコンバインにおいて、前記無線オーガ操作器(11)からの指令電波を受信するアンテナ(23)と該指令電波に基づいて制御信号を出力するオーガ制御ボックス(26)を揚穀筒(24)の後で機体後側部に取り付けた。【選択図】図5
