PROBLEM TO BE SOLVED: To smooth transportation of reaped grain culms in a combine harvester.SOLUTION: An apparatus for transporting the grain culms of the combine harvester is obtained as follows. A continuously variable transmission 38 for traveling is installed in a traveling transmission route of the combine harvester 1. Transporting apparatuses 8a, 8b and 8c of a reaping transporting part 8, a feed chain 19 and a continuously variable transmission 67 for transportation changing the transportation speed of a waste straw transporting apparatus 21 are installed. When the speed of the continuously variable transmission 38 for traveling is changed to change the traveling speed with a traveling speed change lever 82, the speed of the continuously variable transmission 67 for the transportation is changed synchronously with the speed change of the traveling speed at a prescribed ratio. Thereby, the transportation speeds of the transporting apparatuses 8a, 8b and 8c of the reaping transporting part 8, the feed chain 19 and the waste straw transporting apparatus 21 which are a series of transportation systems are changed.COPYRIGHT: (C)2007,JPO&INPIT【課題】コンバインにおいて刈取穀稈の搬送を円滑にする。【解決手段】コンバイン1の走行伝動経路に走行用無段変速装置38を設け、刈取搬送部8の搬送装置8a,8b,8c、フィードチエン19及び排稾搬送装置21の搬送速度を変速する搬送用無段変速装置67を設ける。走行変速レバー82により走行用無段変速装置38を変速し走行速度を変速すると、この走行速度の変速に同調して搬送用無段変速装置67を所定比率で変速し、一連の刈取搬送部8の搬送装置8a,8b,8c、フィードチエン19及び排稾搬送装置21の搬送速度を変速する。【選択図】図2
