PROBLEM TO BE SOLVED: To provide a self-propelled roll baler equipped with a cutting member having a sufficient power for finely cutting feed crops and a sufficient force for feeding the shredded feed crops.SOLUTION: The self-propelled roll baler includes a reaping portion for reaping feed crops a convey-supplying portion for finely cutting and convey-supplying the feed crops reaped in the reaping portion and a baler-forming portion for processing the cut feed crop convey-supplied in the convey-supplying portion into approximately cylindrical bales, wherein a finely cutting member for cutting and forcefully conveying the feed crops is disposed in the convey-supplying portion in the finely cutting member, many finely cutting blades are extended in the radial direction of a rotation axis and projectedly disposed on the outer circumferential surface of the rotation axis horizontally built in the direction orthogonal to the direction for convey-supplying the finely cut feed crops in the convey-supplying portion and belt-like forcefully conveying blades extended in the axial direction of the rotation axis are disposed on the rotation sides of the base portions of the finely cutting blades.COPYRIGHT: (C)2013,JPO&INPIT【課題】飼料作物の十分な細断力と細断飼料作物の十分な送給力を有する細断体を備えた自走式ロールベーラを提供すること。【解決手段】飼料作物を刈り取る刈取部と、刈取部により刈り取った飼料作物を細断するとともに送給する送給部と、送給部により送給された細断飼料作物を略円柱状のベールとなすベーラ形成部とを具備する自走式ロールベーラ。送給部には飼料作物を細断して圧送する細断体を配設するとともに、細断体は、軸線を細断飼料作物の送給方向と直交する方向に向けて横架した回転軸の外周面に、多数の細断刃を回転軸の半径方向に伸延させて突設し、細断刃の基部の回転側に回転軸の軸線方向に伸延する帯状の圧送羽根を設けた。【選択図】図8
