It is configured to receive the processed material leaking from the handling chamber 14 due to the joint action of the sorting wind and the swing, and perform the sieving sorting process while swinging and transferring.

そして、唐箕３１の選別風は、上段風路Ａと中段風路Ｂと下段風路Ｃに分かれている。上段風路Ａは、チャフシ－ブ３６の前端部に向けて選別風が送られて、選別初期の処理物の塊などを分解して選別を促進及び向上させる。中段風路Ｂは、チャフシ－ブ３６の中央部に向けて選別風が送られて、枝梗粒（枝梗に穀粒が付いたままのもの）が１番棚先３９を越えるように吹き飛ばし、２番移送螺旋３３に送って２番処理胴２１にて再処理する。下段風路Ｃは、１番棚先３９に向けて選別風が送られて、処理物が１番棚先３９を越えて２番移送螺旋３３に送られるのを助長する。 The sorting wind of the wall insert 31 is divided into an upper air passage A, a middle air passage B, and a lower air passage C. In the upper air passage A, the sorting air is sent toward the front end portion of the chaf sieve 36 to decompose a mass or the like of the processed material at the initial stage of sorting to promote and improve the sorting. In the middle air passage B, a sorting wind is sent toward the central part of the chaf sieve 36, and the branch stalks (the ones with the grains still attached to the branch stalks) are blown off so as to exceed the first shelf tip 39. No. 2 is sent to the No. 2 transfer spiral 33 and reprocessed by the No. 2 processing cylinder 21. The lower air passage C promotes that the sorting wind is sent toward the first shelf tip 39 and the processed material is sent over the first shelf tip 39 to the second transfer spiral 33.

そして、選別網３８の下方には、中段風路Ｂの選別風がチャフシ－ブ３６の中央部に下方から上方に向けて送られるように、中段風路Ｂの選別風を案内するガイド部材４０が設けられている。よって、ガイド部材４０にて中段風路Ｂの選別風がチャフシ－ブ３６の中央部に下方から上方に向けて送られ、枝梗粒が１番棚先３９を越えるように吹き飛ばされて、効率的に穀粒と藁屑を分別することができる。 Then, below the sorting net 38, a guide member 40 that guides the sorting wind of the middle stage air passage B so that the sorting wind of the middle stage air passage B is sent from the lower side to the upper side to the central portion of the chaf sieve 36. Is provided. Therefore, the sorting wind of the middle air passage B is sent from the lower side to the upper side by the guide member 40 to the central portion of the chaf sieve 36, and the branch stalk grains are blown off so as to exceed the first shelf tip 39, resulting in efficiency. It is possible to separate grain and straw waste.

ガイド部材４０は、選別網３８と１番移送螺旋３２の間且つ選別網３８と１番棚先３９の間に配置され、選別室の左右側壁間に亘って設けられた板体で構成されている。 The guide member 40 is arranged between the sorting net 38 and the first transfer spiral 32 and between the sorting net 38 and the first shelf tip 39, and is composed of a plate body provided between the left and right side walls of the sorting chamber. There is.

また、ガイド部材４０は、１番棚先３９を構成する部材に選別網３８と略平行に前後方向に３つのステー４０ａを設け、該ステー４０ａに着脱自在にボルト４０ｂにて固定されている。従って、ガイド部材４０を前後方向に設けた３つのステー４０ａの何れに取り付けるかで、ガイド部材４０の前後方向の位置調節ができる。なお、１番棚先３９を構成する部材は、選別室の側壁に着脱自在に設けているので、ガイド部材４０は、１番棚先３９を構成する部材と共に着脱することができる。 Further, the guide member 40 is provided with three stays 40a in the front-rear direction substantially parallel to the sorting net 38 on the member constituting the first shelf tip 39, and is detachably fixed to the stay 40a with bolts 40b. Therefore, the position of the guide member 40 can be adjusted in the front-rear direction depending on which of the three stays 40a provided in the front-rear direction is attached to the guide member 40. Since the member constituting the first shelf tip 39 is detachably provided on the side wall of the sorting chamber, the guide member 40 can be attached and detached together with the member constituting the first shelf tip 39.

そして、図４に示すように、選別室の側壁の１番棚先３９を構成する部材がある部分には、孔４１が開いており、該孔４１は蓋部材４２をボルトで止めることにより塞がれている。 Then, as shown in FIG. 4, a hole 41 is opened in a portion of the side wall of the sorting chamber where the member constituting the first shelf tip 39 is located, and the hole 41 is closed by fastening the lid member 42 with a bolt. It is missing.

従って、蓋部材４２を外すと、孔４１から１番棚先３９を構成する部材やガイド部材４０のメンテナンスが容易に行なえると共に、ガイド部材４０の前後位置を容易に変更調整できる。 Therefore, when the lid member 42 is removed, maintenance of the member constituting the first shelf tip 39 and the guide member 40 can be easily performed from the hole 41, and the front-rear position of the guide member 40 can be easily changed and adjusted.

稲の場合は、枝梗粒が多いので、ガイド部材４０を後側に位置調節して、枝梗粒が１番棚先３９を越えるように吹き飛ばされやすくする。 In the case of rice, since there are many branch stalk grains, the position of the guide member 40 is adjusted to the rear side so that the branch stalk grains are easily blown off so as to exceed the first shelf tip 39.

麦の場合は、脱粒しやすいが藁屑が多いので、ガイド部材４０を前側に位置調節して、効率的に穀粒と藁屑を分別する。 In the case of wheat, it is easy to shed, but there is a lot of straw waste, so the position of the guide member 40 is adjusted to the front side to efficiently separate the grain and the straw waste.

なお、ガイド部材４０は、１番棚先３９後端よりも低い位置で、中段風路Ｂのガイド壁上端Ｐよりも高い位置に配置している。従って、ガイド部材４０により、中段風路Ｂの選別風が選別網３８及びその上方のチャフシ－ブ３６に向けて案内され、効率的に穀粒と藁屑を分別することができる。 The guide member 40 is arranged at a position lower than the rear end of the first shelf 39 and higher than the upper end P of the guide wall of the middle air passage B. Therefore, the guide member 40 guides the sorting wind of the middle air passage B toward the sorting net 38 and the chaf sieve 36 above the sorting net 38, and can efficiently separate grains and straw debris.
