That is, a treatment cylinder (7) in which a large number of teeth (7a) are planted is pivotally supported between the front side wall (5a) and the rear side wall (6b) of the threshing chamber (6). 6) A takeover portion (6c) is provided for communicating the rear end portion with the front end portion of the dust removal treatment chamber (8), and a large number of dust removal treatment teeth (9a) are provided in the dust removal treatment chamber (8). The dust removal cylinder (9) is pivotally supported, the second treatment chamber (24) is provided on the front side of the dust removal treatment chamber (8), and a continuous spiral ( In the threshing device constructed by pivotally supporting the second processing cylinder (24a) having 24b), an intermediate partition wall (6a) is provided at a position a predetermined distance ahead of the rear wall (6b) of the threshing chamber (6). The transfer part (6c) is formed between the rear side wall (6b) and the intermediate partition wall (6a), and the feed teeth (7c) located behind the intermediate partition wall (6a) are fed. Direction Is set to be larger than the inclination angle of the feed teeth (7c) positioned in front of the intermediate partition wall (6a) in the feed direction, and the handling chamber receiving net (7e) of the takeover portion (6c) is set. A threshing apparatus characterized in that the filtration degree (b) is set larger than the filtration degree (b) of the handling room receiving net (7e) located in front of the intermediate partition wall (6a). It is.

刈取り済みの穀稈の脱穀は、脱穀装置の前側壁５ａと後側壁６ｂとの間に軸支した扱胴７の多数の扱歯７ａで脱穀される。該脱穀室６内で発生した脱穀排塵物は、後側壁６ｂと中間仕切壁６ａとの間に形成される引継部６ｃから排塵処理室８内に供給され、排塵処理胴９によって後方へ移送されながら処理される。一方、枝梗付着粒などの二番物は、二番処理室２４に供給され、二番処理胴２４ａの連続の螺旋２４ｂによって移送されながら処理される。 The threshing of the harvested cereal is threshed by a large number of teeth 7a of the barrel 7 pivotally supported between the front side wall 5a and the rear side wall 6b of the threshing device. The threshing dust generated in the threshing chamber 6 is supplied into the dust processing chamber 8 from the takeover portion 6 c formed between the rear side wall 6 b and the intermediate partition wall 6 a, and is moved backward by the dust processing cylinder 9. It is processed while being transferred to. On the other hand, the second thing such as the branch leaf adhering grains is supplied to the second processing chamber 24 and processed while being transferred by the continuous spiral 24b of the second processing cylinder 24a.

このような脱穀処理において、中間仕切壁６ａよりも後側に位置する扱歯７ｃの送り方向の傾斜角度が、該中間仕切壁６ａよりも前側に位置する扱歯７ｃの送り方向の傾斜角度よりも大きく設定され、引継部６ｃにおける扱室受網７ｅの濾過目合（イ）が、中間仕切壁６ａよりも前側に位置する扱室受網７ｅの濾過目合（ロ）よりも大きく設定されているために、この引継部６ｃにおける脱穀排塵物の後方への排出および下方への漏下が促進される。 In such a threshing process, the inclination angle in the feeding direction of the tooth handling 7c located on the rear side of the intermediate partition wall 6a is larger than the inclination angle in the feeding direction of the tooth handling 7c located on the front side of the intermediate partition wall 6a. Is set larger, and the filtering degree (b) of the handling chamber receiving net 7e in the takeover portion 6c is set larger than the filtering degree (b) of the handling chamber receiving net 7e located in front of the intermediate partition wall 6a. Therefore, the rearward discharge and the downward leakage of the threshing dust in the takeover portion 6c are promoted.

この発明によると、中間仕切壁６ａよりも後側に位置する扱歯７ｃの送り方向の傾斜角度を、該中間仕切壁６ａよりも前側に位置する扱歯７ｃの送り方向の傾斜角度よりも大きく設定し、引継部６ｃにおける扱室受網７ｅの濾過目合（イ）を、中間仕切壁６ａよりも前側に位置する扱室受網７ｅの濾過目合（ロ）よりも大きく設定することによって、脱穀室６内で多量の藁屑が発生しても、この引継部６ｃにおける脱穀排塵物の後方への排出および下方への漏下を促進して、該引継部６ｃにおける脱穀排塵物の詰まりを少なくして、脱穀作業の能率を向上させることができる。また、脱穀装置から外部へ穀粒を飛散させてしまうような収穫損失を少なくできると共に、脱穀装置の駆動負荷を減少させて、例えばこの脱穀装置を搭載するコンバインの馬力損失を少なくして作業能率を向上させることができる。 According to the present invention, the inclination angle in the feeding direction of the tooth handling 7c located on the rear side of the intermediate partition wall 6a is larger than the inclination angle in the feeding direction of the tooth handling 7c located on the front side of the intermediate partition wall 6a. By setting and setting the filtration degree (b) of the handling chamber receiving net 7e in the takeover part 6c larger than the filtering degree (b) of the handling chamber receiving net 7e located in front of the intermediate partition wall 6a Even if a large amount of swarf is generated in the threshing chamber 6, the threshing dust in the takeover portion 6c is promoted to discharge backward and leak downward in the takeover portion 6c. The efficiency of the threshing work can be improved by reducing clogging. In addition, it is possible to reduce the harvest loss that causes the grains to scatter from the threshing device to the outside, and to reduce the driving load of the threshing device, for example, to reduce the horsepower loss of the combine equipped with this threshing device. Can be improved.
