PROBLEM TO BE SOLVED: To solve the problem that in a conventional combine in which an intake pipe with a pre-cleaner is elongated to an upper part of the body in the neighborhood of the side part of the body, and an exhaust pipe from a DPF is caused to be located below a horizontal auger part of a grain discharge unit, the tail end of which is directed backward, the density of dust such as waste straw becomes high in the side part of the body so that there is a high possibility of foreign matter entering intake air.SOLUTION: In a combine, a DPF unit 10 and an exhaust pipe 14 are provided in a space between a threshing part 5 and a storage part 6, and a pre-cleaner 11 disposed at the upper end part of an intake pipe 13 connected to an intake port of an engine 17, and an exhaust port 14c at the end edge of the exhaust pipe 14 are located above the grain tank 18, the exhaust port 14c being caused to open toward the direction away from the pre-cleaner (11).COPYRIGHT: (C)2014,JPO&INPIT【課題】従来のコンバインにおいては、プレクリーナ付きの吸気管は機体側部近傍で機体上部まで延伸させ、かつDPFからの排気管は、穀粒排出機の水平オーガ部分よりも下方に位置させ、そのテールエンドを後方に向ける構成としていたが、機体側部は藁屑などの塵埃の密度が高くなり、吸気への異物混入の確率が高くなるという問題点があった。【解決手段】脱穀部5と貯留部6との間の空間に、DPFユニット10と排気管14と、を備え、かつエンジン17の吸気口に接続される吸気管13の上端部に設けたプレクリーナ11と、排気管14終端の排出口14cとを前記グレンタンク18よりも上方に配置し、前記排出口14cをプレクリーナ(11)から離れる方向へ向けて開口させたコンバインにより上記問題を解決した。【選択図】図1
