PROBLEM TO BE SOLVED: To improve a collection rate of grain culms, and to smoothly perform reaping/threshing operation with a combine harvester by preventing drop of grain culms by interference of the conveyed grain culms and the periphery of a supply port of a threshing device.SOLUTION: The combine harvester includes: a stub base transfer device (10a) and an ear tip transfer device (12) for conveying and supplying the reaped grain culms reaped by a reaping deice (4) at the front part of the machine body to the threshing device (2a) provided at the rear side of the reaping device (4) and a first ear tip leading rod (30a) for pressing the ear tip of the grain culms at the upper side of the ear tip transfer device (12). The combine harvester is provided with a second ear tip leading rod (30b) extending rearward more than the conveyance termination of the ear tip transfer device (12) is provided at a conveyance lower side position of the first ear tip leading rod (30a).COPYRIGHT: (C)2012,JPO&INPIT【課題】搬送穀稈と脱穀装置の供給口周辺との干渉による穀粒の脱粒を防いで、穀粒の回収率を高めると共に、コンバインによる刈取脱穀作業を円滑に行なえるものとする。【解決手段】機体前部の刈取装置(4)で刈り取った刈取穀稈を該刈取装置(4)の後側に設けた脱穀装置(2a)に搬送供給する株元移送装置(10a)と穂先移送装置(12)を設け、該穂先移送装置(12)の上側で穀稈の穂先を押える第一穂先誘導杆(30a)を設けたコンバインにおいて、第一穂先誘導杆(30a)の搬送下手側の位置に、穂先移送装置(12)の搬送終端よりも後方に延出する第二穂先誘導杆(30b)を設ける。【選択図】図2
