PROBLEM TO BE SOLVED: To provide a threshing device capable of simply and inexpensively configuring switching of presence/absence of air flow of sorting air sent to an upper face side of a grain pan and switching of strength of the sorting air in the threshing device improving sorting performance by sending the sorting air to the upper face of the grain pan.SOLUTION: The threshing device includes: an oscillation sorting body 31 and a blower fan 34 generating sorting air. The oscillation sorting body 31 includes: a grain pan 38 a chaff sieve 39 and a grain sieve 42. A conveyance face 38a conveying processing objects rearward is formed on an upper face of the grain pan 38 and the sorting air is made to flow to the conveyance face 38a side. Attachable/detachable adjustment members 52, 54, 56 are arranged in the middle of a flow passage from the blower fan 34 to the conveyance face 38a side. By attachment/detachment of the adjustment members 52, 54, 56, air flow of the sorting air flowing to the conveyance face 38a side is adjusted or presence/absence of the sorting air is switched.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】グレンパンの上面側に選別風を送風して選別能力を向上させる脱穀装置において、グレンパンの上面側に送風される選別風の風量の有無の切換えや、該選別風の強弱の切換えを簡易且つ安価に構成できる脱穀装置を提供することを課題とする。【解決手段】揺動選別体31と、選別風を起風する送風ファン34とを備え、前記揺動選別体31は、グレンパン38と、チャフシーブ39と、グレンシーブ42とを有し、該グレンパン38の上面には、処理物を後方搬送する搬送面38aを形成し、該搬送面38a側に上記選別風を流動させる構造とした脱穀装置において、前記送風ファン34から搬送面38a側への流動経路の途中に、着脱可能な調整部材52,54,56を設け、該調整部材52,54,56の着脱によって、搬送面38a側に流動する選別風の風量を調整するか、或いは選別風の有無を切換える構造とした。【選択図】図5
