PROBLEM TO BE SOLVED: To solve such problems as a decline in efficiency of removing dust inside a conveying elevator for conveying grain culms from a reaper to a thresher, and contamination of grains, etc.SOLUTION: A base of the reaper 6 is attached to the distal end of the conveying elevator 20 connected to the thresher 3. The conveying elevator 20 includes a conveyor 25 inside a square pillar-shaped conveyor case 24, and a swelling part 30 is formed at a prescribed position in the middle in the longitudinal direction of a top plate 23 of the conveyor case 24. A dust sucking and discharging fan 33 for sucking dust within the conveyor case 24 is disposed on a distal end top plate 32 at a position more toward the distal end side than the swelling part 30. A rotation axis 37 of the dust sucking and discharging fan 33 is inclined so that the longer one of the distance from the attached part of the conveyor case 24 with the reaping device 6 to a left sidewall 10L and the distance from the attached part to a right sidewall 10R is lower than the other side.COPYRIGHT: (C)2012,JPO&INPIT【課題】刈取装置から脱穀装置へ穀稈を搬送する搬送エレベーター内の塵埃の除去の効率低下。穀粒の汚染。【解決手段】刈取装置6の基部を前記脱穀装置3に接続した搬送エレベーター20の先端に取付ける。搬送エレベーター20は四角筒形状に形成した搬送ケース24内に搬送コンベア25を設けた構成とし、搬送ケース24の天板23の前後方向の中間所定位置に膨出部30を形成する。膨出部30より先端側の部位の先端側天板32に搬送ケース24内の塵埃を吸引する吸引排塵ファン33を設ける。搬送ケース24と刈取装置6との取付部分から左の側壁10Lまでの距離と、該取付部分から右の側壁10Rまでの距離とのうち、何れか距離の大きい側が低くなるように、吸引排塵ファン33の回転軸37を傾斜させたことを特徴とするコンバイン。【選択図】図3
