PROBLEM TO BE SOLVED: To provide a swinging selection device for a threshing machine, having material adaptability improved by devising the arrangement of a drawing plate on a chaff sieve.SOLUTION: The swinging selection device 2 includes a sub-feed pan 13 for receiving a dropped selected product and flowing the selected product to the rear side at the upper side of the chaff sieve 12, and the drawing plate 25 present at the lower side of the sub-feed pan 13, having a clearance h between the drawing plate 25 and the upper surface of the chaff sieve 12, and dispersing the selected product on the chaff sieve 12. As a result, the drawing plate 25 can prevent the selected product from being accumulated on the drawing plate 25, allows the selected product to pass through the clearance h between the drawing plate 25 and the upper surface of the chaff sieve 12, and capable of making the thickness of the layer constant by dispersing the selected product to improve the material adaptability.COPYRIGHT: (C)2010,JPO&INPIT【課題】チャフシーブ上における寄せ板の配置を工夫することで、材料適応性を向上させることが可能な脱穀機の揺動選別装置を提供する。【解決手段】揺動選別装置2は、チャフシーブ12の上方に、落下してくる選別物を受けて後方側に向けて流動させるサブフィードパン13と、該サブフィードパン13の下方で、チャフシーブ12の上面との間に隙間hを有し、チャフシーブ12上の選別物を分散させる寄せ板25を設けている。これにより、寄せ板25は、該寄せ板25上に選別物が堆積することを防ぐことができると共に、チャフシーブ12上面との間の隙間hから選別物を通過させることができ、選別物を分散させ層厚を一定にすることができて、材料適応性を向上させることができる。【選択図】図1
