PROBLEM TO BE SOLVED: To solve a problem occurring in a cutting device of waste culms that an amount of the waste culms discharged without being cut increases due to a large holding angle at which the waste culms are held by rotary blades and a cutting blade, the large angle caused by the cutting blade required to be rotated to a retreat direction in the case of large cutting resistance of the waste culms.SOLUTION: The combine is configured such that grain culms raked in by a raking-in reel 7 of a reaping device 4 and reaped by a reaping blade 8 are fed to a threshing device 3 to be threshed. The combine includes a cutting processing device 20 installed at a rear part of the threshing device 3 and processing by cutting waste culms or the like discharged from the threshing device 3, the cutting processing device including rotary blades 21 arranged parallelly to each other on a cutting processing cylinder 23 in the right/left direction, a cutting blade 22 entering partially into a rotary locus of the rotary blades 21, only a part of the cutting blade 22 formed with a saw-like saw blade part 33.COPYRIGHT: (C)2016,JPO&INPIT【課題】排稈の切断装置では、排稈の切断抵抗が大きいときには、切刃を退避方向に回動させる必要があり、この場合、回転刃と切刃の排稈を挟む挟み角が大きくなって、切断されずに排出される排稈量が増加という課題がある。【解決手段】刈取装置4の掻込リール7により掻き込んで刈刃8により刈り取った穀稈を脱穀装置3に供給して脱穀する構成とし、該脱穀装置3の後部に脱穀装置3から排出される排稈等を切断処理する切断処理装置20を設け、該切断処理装置20は、左右方向の切断処理胴23に並設した回転刃21と、該回転刃21の回転軌跡内に一部が入り込む切刃22とを設けて構成し、切刃22の一部のみには、鋸状の鋸刃部33を形成したコンバイン。【選択図】図3
