PROBLEM TO BE SOLVED: To provide a combine harvester facilitating the uniform insertion of grains to a carrier of a truck.SOLUTION: The combine harvester includes a traveling machine body, and an unloading auger 12 for unloading the grains stored in the traveling machine body side from an unloading opening 13, having the unloading opening 13 for unloading the grains, formed at the tip side, and the base terminal side supported by the traveling machine body side so that the posture can be changed, and is constituted as follows. An unloading cover body 18 for preventing the grains from being scattered from the unloading opening 13 by covering the surroundings of the lower side of the unloading opening 13 is installed, and one guide plate 28 is arranged at the side near to the tip of the unloading auger 12 in the inner surface side of the unloading cover body 18. The upper terminal part of the guide plate 28 is supported turnably so that the lower part of the guide plate 28 can part or approach from or to the tip-side side wall 24 of the side wall at the side near to the tip side of the unloading auger 12 in the unloading cover body 18, and an operation means for operating the tilted angle of the guide plate 28 to the tip-side side wall 24 so as to be changed is installed.COPYRIGHT: (C)2011,JPO&INPIT【課題】トラックの荷台に均一に穀粒を投入することが容易なコンバインを提供する。【解決手段】走行機体と、先端側に穀粒を排出する排出口13が形成されるとともに姿勢変更可能なように基端側が走行機体側に支持されて走行機体側に収容された穀粒を排出口13から排出せしめる排出オーガ12とを備えたコンバインにおいて、排出口13の下側周囲を覆って排出口13からの穀粒の飛散を防止する排出カバー体18を設けるとともに、該排出カバー体18の内面側における排出オーガ12先端寄り側に1つのガイド板28を配置し、排出カバー体18における排出オーガ12先端側に近い側の側壁である先端側側壁24に対してガイド板28の下部が離間・近接するようにガイド板28の上端部を回動可能に支持し、ガイド板28の前記先端側側壁24に対する傾斜角を変更操作する操作手段を設けた。【選択図】図7
