PROBLEM TO BE SOLVED: To provide a shredding device in which straw waste or residual stems are hardly wound on the outer surface of a driving shaft between adjacent cutting blades in the axial direction of the driving shaft, and the straw waste or residual stems can be easily removed, even when the straw waste or residual stems are wound on the driving shaft.SOLUTION: A shredding device includes a plurality of cutting blades 100 extended from a driving shaft 48 to the outside in the radial direction at different positions along the circumferential direction of the driving shaft 48 and at different positions along the axial direction of the driving shaft 48. The cutting device includes a plurality of bar-like members 101 integrally rotatable with the driving shaft 48 at positions with a set space from the outer surface of the driving shaft 48 to the outside in the radial direction of the driving shaft 48, between the outer surface of the driving shaft 48 and outer ends in the radial direction of the cutting blades 100, in postures along the axial direction of the driving shaft 48, and at different positions along the circumferential direction of the driving shaft 48.COPYRIGHT: (C)2013,JPO&INPIT【課題】細断装置において、駆動軸の軸芯方向に隣接する細断刃の間の駆動軸の外表面にワラ屑や残幹が巻き付き難いように、ワラ屑や残幹が巻き付いても容易にワラ屑や残幹を取り除くことができるように構成する。【解決手段】駆動軸48から半径方向外側に延出された複数の細断刃100を、駆動軸48の円周方向に沿った異なる位置で且つ駆動軸48の軸芯方向に沿った異なる位置に備える。複数の棒状部材101を、駆動軸48の外表面から駆動軸48の半径方向外側に設定間隔を置いた位置で、且つ、駆動軸48の外表面と細断刃100の半径方向外端部との間で、且つ、駆動軸48の軸芯方向に沿った姿勢で、且つ、駆動軸48の円周方向に沿った異なる位置に、駆動軸48と一体回転自在に備える。【選択図】図17
