PROBLEM TO BE SOLVED: To prevent clogging in conveyance and unthreshed remains of grain culms by bringing delivery of reaped and conveyed grain culms to a threshing feed chain to be satisfactory to deliver and guide in a normal posture, even when the amount of reaped grain culms is reduced, with no feeding of plant feet in advance.SOLUTION: Above problem is solved by arranging the conveyance starting point of a threshing feed chain (10) to be lower than the conveyance end point of a delivery conveying chain (13), equipping a guide plate (15) for supporting the feet of grain culms delivered from the conveyance device (9) on the upper side of the starting point of conveyance of the threshing feed chain (10), and constituting the guide plate (15) to be elastically displaced to the side of the threshing feed chain (10) by the load of the grain culms.COPYRIGHT: (C)2014,JPO&INPIT【課題】脱穀フィードチェンへの刈取搬送穀稈の受け渡しを良好にし、刈取穀稈量が少なくなっても正常な姿勢で引継ぎ案内し、株元先行送りをなくして穀稈の搬送詰まりや扱ぎ残しを防止する。【解決手段】 上記の課題は、脱穀フィードチェン(10)の搬送始端部を引継ぎ搬送チェン(13)の搬送始端部よりも低く配置し、脱穀フィードチェン(10)の搬送始端部の上側に、搬送装置(9)から受け渡される穀稈の株元を下側から支持するガイドプレート(15)を備え、ガイドプレート(15)が、穀稈の荷重によって脱穀フィードチェン(10)側へ弾性変位する構成とすることで解決される。【選択図】 図3
