PROBLEM TO BE SOLVED: To provide a threshing and sorting device which improves sorting performance of a grain sieve of an oscillation sorting shelf and can appropriately adjust an air direction and an air quantity in an upper air passage and a lower air passage according to a work state of a combine.SOLUTION: A main winnower 16 includes an air divider 66 between a top face 67 and a bottom face 68 of a blow port 65, the top face 67 is configured to be rotatable so that a portion on a downstream side in an air blow direction is moved upward/downward, a vertical rotation center of the air divider 66 is placed in a center portion in the air blow direction, and the top face 67 and the air divider 66 are configured to be rotated while interlocked with each other in the same rotation direction. A sub winnower 101 is placed in a lower portion of a transfer shelf 22 in a front side part of an oscillation sorting shelf 20 in a front side part of a sorting chamber 18 and in a front side part of the main winnower 16. The sub winnower 101 blows sorting air to a rear upper side, thereby blowing air to a front side of a grain sieve 23 following the transfer shelf 22 of the oscillation sorting shelf 20.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】 揺動選別棚のグレンシーブの選別性能を向上させ、コンバインの作業状態に応じて上側風路及び下側風路の風向及び風量を適正に調整できる脱穀選別装置を提供する。【解決手段】 主唐箕(16)は、送風口(65)の天面部(67)と底面部(68)との間に風割(66)を有し、前記天面部(67)はその送風方向下流側の部位が上下するように回動自在に構成し、前記風割(66)の上下回動中心を送風方向中間の部位に配置し、前記天面部(67)及び風割(66)は、同じ回動方向に連動して回動するように構成し、前記選別室(18)の前側部における揺動選別棚(20)前側部の移送棚部(22)の下方部位で且つ前記主唐箕(16)の前側部に副唐箕(101)を配置し、該副唐箕(101)によって、選別風を後上方へ送風して揺動選別棚(20)の移送棚部(22)に後続するグレンシーブ(23)の前側部に送風する。【選択図】図5
