PROBLEM TO BE SOLVED: To provide a threshing sorting structure of a combine in which high sorting precision can be secured even if a large quantity of processed products is supplied to swinging sorting means.SOLUTION: A threshing sorting structure of a combine includes a second chaff sheave 50 for performing sieve sorting processing to a second processed product supplied to the rear of swinging sorting means 20. The threshing sorting structure is disposed of a second winnower 23 for supplying a sorting air for use in sorting the second article passing through the lower part of the second chaff sheave 50 and blowing to the rear upper part from the rear end of the second chaff sheave 50 by rotating mainly on the second winnower shaft 57 for right and left directions in the front and lower part of the second chaff sheave 50. An air outlet 58A of the second winnower 23 is formed in a tapered shape such that a vertical interval becomes narrower as the downstream side in the blowing-out direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】大量の処理物が揺動選別手段に供給される場合であっても高い選別精度を確保できるコンバインの脱穀選別構造を提供する。【解決手段】揺動選別手段20の後部に供給される2番処理物に篩い選別処理を施す2番チャフシーブ50を備え、2番チャフシーブ50の前下方に、左右向きの2番唐箕軸57を中心に回転することで、2番チャフシーブ50の下方を通過して2番チャフシーブ50の後端部から後上方に吹き抜ける2番物選別用の選別風を供給する2番唐箕23を配備し、2番唐箕23の吹出口58Aを、その吹き出し方向下手側ほど上下間隔が狭くなる先窄み形状に形成してある。【選択図】図3
