PROBLEM TO BE SOLVED: To provide a combine harvester which includes a detection body provided vertically swingably at a lower part side of a reaping part liftably provided in a traveling machine body, and detecting a ground height of the reaping part, and can compactly arrange the detection body and a detection sensor.SOLUTION: A combine harvester includes: a reaping part 4 liftably connected to the front part of a traveling machine body 3 a detection body 30 vertically swingably supported on the lower end part of the reaping part 4 and made vertically swingable by grounding on the ground surface a grounding part 39a grounding on the ground surface so as to make the detection body 30 vertically swingable a detection sensor 31 fixed to a reaping part 4 side so as to detect the vertical swinging position of the detection body 30 and a bracket 23 supporting the detection body 30 and the detection sensor 31 on the lower part side of the reaping part 4. The detection body 30 is arranged at one of the right and left lateral face sides of the bracket 23, and the detection sensor 31 is arranged at the other of the right and left lateral face side of the bracket 23.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】走行機体に昇降可能に設けた刈取部の下部側に上下揺動可能に設けられて、刈取部の対地高さを検出する検知体を備えたコンバインにおいて、前記検知体及び検出センサをコンパクトに配置することのできるコンバインを提供することを課題としている。【解決手段】本発明は、走行機体3の前部に昇降可能に連結された刈取部4と、該刈取部4の下端部に上下揺動可能に支持されるとともに、地面に接地することにより上下揺動される検知体30と、該検知体30が上下揺動されるように地面に接地する接地部39aと、該検知体30の上下揺動位置を検出するように前記刈取部4側に固定された検出センサ31と、前記刈取部4の下部側に前記検知体30及び検出センサ31を支持するブラケット23とを備え、前記ブラケット23の左右一方の側面側に前記検知体30が配置され、該ブラケット23の左右他方の側面側に前記検出センサ31が配置された。【選択図】図3
