And chaff sieve (36) Renshibu constitute the grain and dust falling from (37) sorting air from winnowing fan (39) so that each stabilize improve sorting performance separately reacted. Further, the upper and lower sieving action of the sieving line (35) can promote the dispersal of grains, dust and straw in the rear feed pan (34) and the chaff sieve (36), and can enhance the sieving line (35). To the reduction port (42a) of the second reduction conveyor (42) so as to disperse the second reduction material and effectively enable processing of large-capacity grains within a limited sorting width. It is what was constituted.
上記から明らかなように、フィードパン（３３）とチャフシーブ（３６）を揺動選別盤（３２）に備えるコンバインにおいて、フィードパン（３３）の脱粒物を風選する副送風口（６４）と、チャフシーブ（３６）の脱粒物を風選する主送風口（６５ｂ）とを設ける。そして、フィードパン（３３）から送り出される脱粒物を副送風口（６４）からの選別風によって風選することにより、脱粒物中の下層側の藁屑を上層側に移動させることができ、かつ脱粒物を揺動選別盤（３２）の左右幅方向に分散させることができ、チャフシーブ（３６）の選別処理能力の向上並びにチャフシーブ（３６）構造の簡略化などを行うことができる。 As is clear from the above, in a combine provided with the feed pan (33) and the chaff sheave (36) in the swinging sorter (32), a sub-blower (64) for selecting the crushed material of the feed pan (33), A main air outlet (65b) for air-filtering the shattered material of the chaff sheave (36) is provided. Then, by selecting the degranulated material sent out from the feed pan (33) by the sorting wind from the sub-blower port (64), the lower layer of the flaked material can be moved to the upper layer side, and The agglomerates can be dispersed in the left-right width direction of the rocking sorter (32), so that the sorting processing capacity of the chaff sheave (36) can be improved and the structure of the chaff sheave (36) can be simplified.
また、フィードパン（３３）とチャフシーブ（３６）を揺動選別盤（３２）に備えるコンバインにおいて、フィードパン（３３）の脱粒物を風選する送塵ファン（３７）と、チャフシーブ（３６）の脱粒物を風選する唐箕（３９）とを設ける。そして、フィードパン（３３）から送り出される脱粒物を送塵ファン（３７）からの選別風によって風選することにより、脱粒物中の下層側の藁屑を上層側に移動させることができ、かつ脱粒物を揺動選別盤（３２）の左右幅方向に分散させることができ、チャフシーブ（３６）の選別処理能力の向上並びにチャフシーブ（３６）構造の簡略化などを容易に行うことができる。 Further, in a combine provided with a feed pan (33) and a chaff sheave (36) on a rocking sorter (32), a dust sending fan (37) that wind-selects the deagglomerated matter of the feed pan (33) and a chaff sheave (36). Karin (39), which selects the agglomerates by wind. Then, by wind-selecting the degranulated material sent out from the feed pan (33) by the sorting wind from the dust-feeding fan (37), the lower-layer straw waste in the degranulated material can be moved to the upper layer side, and The agglomerated material can be dispersed in the left-right width direction of the rocking sorter (32), so that the sorting processing capacity of the chaff sheave (36) can be improved and the structure of the chaff sheave (36) can be simplified.
また、フィードパン（３３）の下方で唐箕（３９）の前側に送塵ファン（３７）を設け、フィードパン（３７）から送り出される脱粒物を送塵ファン（３７）によって風選する。そして、フィードパン（３３）の脱粒物の送り終端部に送塵ファン（３７）を近接させてコンパクトに配置させることができ、しかも送塵ファン（３７）の選別風を効率良く供給させて風選能力を向上させることができる。 塵 Further, a dust-feeding fan (37) is provided below the feed pan (33) and in front of the kara-mino (39), and the deagglomerated matter sent out from the feed pan (37) is filtered by the dust-feeding fan (37). Then, the dust sending fan (37) can be arranged compactly by approaching the end of the feed of the degranulated material of the feed pan (33), and the sorting wind of the dust sending fan (37) can be efficiently supplied to the wind fan. You can improve your selection ability.
