PROBLEM TO BE SOLVED: To provide a combine harvester having good sorting performance regardless of kinds of crops.SOLUTION: A combine harvester comprises a threshing device 3 for threshing crops, and a shaking sorting device 41 for shaking and sorting threshed objects threshed by the threshing device 3. The shaking sorting device 41 comprises: a first conveyor 143 (first conveying part) for conveying the threshed objects to a grain tank 51； a second conveyor 144 (second conveying part) for returning the threshed objects to the threshing device 3 or a front end side of the shaking sorting device 41； a grain sieve 416 (first sieve part) located above the first conveyor 143 (first conveying part), and for distributing the threshed objects to the first conveyor 143 (first conveying part) or the second conveyor 144 (second conveying part)； and a first grain flow plate 431 (guide part) for guiding the threshed objects passed through the grain sieve 416 (first sieve part), to the first conveyor 143 (first conveying part). A rear end 416r of the grain sieve 416 (first sieve part) is located behind a rear end 431r of the first grain flow plate 431 (guide part).SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】作物の種類を問わず選別性のよいコンバインを提供する。【解決手段】作物を脱穀処理する脱穀装置３と、脱穀装置３により脱穀された脱穀処理物を揺動選別する揺動選別装置４１と、を有する。揺動選別装置４１は、脱穀処理物をグレンタンク５１に搬送する一番コンベア１４３（第１搬送部）と、脱穀処理物を脱穀装置３又は揺動選別装置４１の前端側に還元する二番コンベア１４４（第２搬送部）と、一番コンベア１４３（第１搬送部）の上方に位置し、脱穀処理物を一番コンベア１４３（第１搬送部）又は二番コンベア１４４（第２搬送部）に振り分けるグレンシーブ４１６（第１篩部）と、グレンシーブ４１６（第１篩部）を通過した脱穀処理物を一番コンベア１４３（第１搬送部）に案内する第一流穀板４３１（案内部）と、を有する。グレンシーブ４１６（第１篩部）の後端４１６ｒは、第一流穀板４３１（案内部）の後端４３１ｒよりも後方に位置する。【選択図】図６
