PROBLEM TO BE SOLVED: To provide a reaping part of a combine harvester by which the vibration and noise caused by a cutting device can be reduced, and grain culms can be cut by the cutting device precisely.SOLUTION: The reaping part of the combine harvester is constituted as follows. A reaping frame 110 includes a plurality of grass-dividing frames 114 having grass-dividing tools at the tip parts. The plurality of the grass-dividing frames 114 is protruded from a threshing part 30 side at the lower part of the cutting device 23 to the grass-dividing tool side and arranged so as to be parallel in the right and left direction at a prescribed interval. The cutting device 23 includes a plurality of disk-shaped cutting blades 231 for cutting the grain culms at the root sides. The plurality of the cutting blades 231 is arranged in a nearly straight same line in the right and left direction so that each cutting blade 231 may position between the grass-dividing frames 114 in the plane view. The neighboring cutting blades 231 in the plurality of the cutting blades 231 are arranged by forming a prescribed interval of the right and left width of the grass-dividing frame 114 between each other.COPYRIGHT: (C)2010,JPO&INPIT【課題】切断装置から発生する振動および騒音を低減し、かつ穀稈を切断装置で確実に切断することができる、コンバインの刈取部を提供する。【解決手段】コンバインの刈取部において、刈取フレーム110には、分草具を先端部に設ける複数の分草フレーム114を備えて、複数の分草フレーム114を切断装置23の下方で脱穀部30側から分草具側へ延出して、左右方向に所定間隔ごとに平行に並設し、切断装置23には、穀稈を株元側で切断する複数の円盤形状の切断刃231を備えて、複数の切断刃231を、各切断刃231が平面視で分草フレーム114間に位置するように、左右方向に略同一直線上に並設し、複数の切断刃231のうち、隣り合う切断刃231を相互間に分草フレーム114の左右幅だけ所定間隔をとって配置する。【選択図】図4
