PROBLEM TO BE SOLVED: To provide a grain culm transport device that transports the whole culms of reaped grain culms and that suppresses deformation or breakage of a member even when a reaped grain culm is caught between a downstream ring body and an endless rotary chain.SOLUTION: A grain culm transport device that transports a whole culm of a reaped grain culm reaped by a reaping unit to a rear side of a machine body comprises a plurality of endless rotary chains 59 wound over a plurality of downstream ring bodies 56 provided on a downstream-side rotary shaft 54, and an upstream ring body 57 on an upstream-side rotary shaft 55, power for transportation and driving is transmitted to the upstream-side rotary shaft 55, the upstream-side ring body 57 is supported on the upstream side rotary shaft 55 so as to be integrally rotatable, and the plurality of downstream-side ring bodies 56 are separately supported so as to rotatable relative to the downstream side rotary shaft 54.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】刈取穀稈の全稈を搬送する穀稈搬送装置において、下手側輪体と無端回動チェーンとの間に刈取穀稈等が挟み込まれることがあっても、部材の変形や破損等が生じ難いようにすることが望まれていた。【解決手段】刈取部にて刈取られた刈取穀稈の全稈を機体後方に向けて搬送する穀稈搬送装置に、下手側回転軸５４に備えられた複数の下手側輪体５６と、上手側回転軸５５に備えられた上手側輪体５７とにわたって複数の無端回動チェーン５９が巻回され、上手側回転軸５５に搬送駆動用の動力が伝達され、且つ、上手側輪体５７が上手側回転軸５５に一体回転可能に支持され、複数の下手側輪体５６が、各別に、下手側回転軸５４に対して相対回転可能に支持されている。【選択図】図３
