Description

本発明は、脱穀装置の扱胴に関するものである。 The present invention relates to a handling cylinder of a threshing apparatus.

従来、機体の前後方向に延伸する扱胴軸の前端部、中間部、及び後端部に固着された支持部材に、多数の扱歯を立設する前後方向の桟部材を架設した扱胴が試みられている（特許文献１参照）。 Conventionally, there has been a handling cylinder in which front and rear crosspiece members are installed on a support member fixed to a front end part, an intermediate part, and a rear end part of a handling cylinder shaft extending in the front-rear direction of the machine body. Attempts have been made (see Patent Document 1).

また、機体の前後方向に延伸する扱胴軸の前端部、中間部、及び後端部に固着された略六角形状の支持部材の頂点部に、多数の扱歯を立設した前後方向の桟部材を架設し、周方向に隣接する桟部材間の空隙を遮蔽板で閉塞した扱胴が試みられている（特許文献２参照）。 In addition, a front-and-rear direction rail having a large number of teeth on the top of a substantially hexagonal support member fixed to the front end portion, intermediate portion, and rear end portion of the handle barrel shaft extending in the front-rear direction of the machine body. A handling cylinder has been attempted in which members are erected and a gap between cross members adjacent in the circumferential direction is closed with a shielding plate (see Patent Document 2).

また、機体の前後方向に延伸する扱胴軸の前端部、中間部、及び後端部に固着された支持部材に、多数の扱歯を立設する前後方向の角パイプを架設した扱胴が試みられている。（特許文献３参照）。 Also, there is a handling cylinder in which square pipes in the front-rear direction for standing a large number of teeth are erected on the support members fixed to the front end part, intermediate part, and rear end part of the handling cylinder shaft extending in the front-rear direction of the machine body. Has been tried. (See Patent Document 3).

しかし、特許文献１に記載された扱胴では、扱室に供給された穀稈が桟部材に絡み、脱粒性能、後方への搬送性能を低下させる虞があった。 However, in the handling cylinder described in Patent Document 1, there is a possibility that the cereal straw supplied to the handling chamber may get entangled with the crosspiece member and reduce the grain removal performance and the backward conveyance performance.

また、特許文献２に記載された扱胴では、胴部の断面形状が六角形状であるため、頂点部間の平面部（遮蔽板）の強度が低く、多量の穀稈が扱室に供給された場合に、この穀稈から受ける反力によって、扱胴外周の平面部が変形する虞があった。 In addition, in the handling cylinder described in Patent Document 2, since the cross-sectional shape of the trunk part is a hexagonal shape, the strength of the plane part (shielding plate) between the apex parts is low, and a large amount of cereals is supplied to the handling room. In such a case, there is a possibility that the flat portion of the outer periphery of the barrel is deformed by the reaction force received from the cereal.

また、特許文献３記載に記載された扱胴では、扱歯を立設する部材が角パイプであるために、この角パイプの角部によって穀粒が損傷したり、藁屑が多量に発生する問題がある。 Moreover, in the handling cylinder described in patent document 3, since the member which erects a tooth-handling is a square pipe, a grain is damaged by the corner | angular part of this square pipe, or a large amount of sawdust is generated. There's a problem.

また、特に、上述のような従来の扱胴では、扱室内において脱穀処理物を後方へ搬送する能力が低く、また、扱室内の容積が小さいために、脱穀する穀稈の丈が長い長稈であったり、穀稈が雨露で濡れているような条件では、扱室内において脱穀処理物の詰りが発生したり、扱室内で発生した藁屑に穀粒が混入したまま外部へ排出され、収穫損失を来す問題がある。 In particular, in the conventional handling cylinder as described above, the ability to convey the threshing processed product backward in the handling chamber is low, and the volume of the handling chamber is small. Or under conditions where the grain buds are wet with rain dew, the threshing product is clogged in the handling chamber, or the grain is mixed with the swarf generated in the handling chamber and discharged to the outside. There is a problem that causes loss.

そこで、本発明は、脱穀する穀稈が長稈であったり、濡れた穀稈であっても、収穫損失を低減しながら、円滑に脱穀処理できる扱胴を提供することを目的としている。 Accordingly, an object of the present invention is to provide a handling cylinder capable of smoothly threshing while reducing harvest loss even if the cereal to be threshed is a long cocoon or a wet cereal.

Moreover, even if the volume in the handling chamber (10) is expanded by the recess (69A) and a long basket or wet cereal is supplied into the handling chamber (10), for example, a lump that has become a lump becomes the recess (69A). By allowing the threshing processed material to enter the recess (69A), such as by evacuating inside, the clogging and overloading in the handling chamber (10) can be reduced, and the threshing operation can be performed smoothly. Can reduce grain harvest loss

請求項２記載の発明によれば、請求項１記載の発明による効果に加えて、掻込螺旋（１６Ａ）の後端部を、筒部（１７）の周方向におけるプレート（１５）の幅内に配置しているので、収穫された穀桿を掻込部（１６）から筒部（１７）にさらに効率良く引継ぐことができる。 According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the rear end portion of the take-up spiral (16A) is set within the width of the plate (15) in the circumferential direction of the tube portion (17). Therefore, the harvested cereal can be more efficiently transferred from the scraping portion (16) to the cylindrical portion (17).

請求項３記載の発明によれば、請求項１又は２記載の発明による効果に加えて、掻込部（１６Ａ）の外周面と、掻込螺旋（１６Ａ）の非搬送作用面に、掻込部（１６Ａ）の周方向に所定の間隔をおいて配置された複数の補強板（１６Ｂ）を連結し、補強板（１６Ｂ）の周方向の配置間隔を、掻込螺旋（１６Ａ）の前端部（１６Ｃ）から後端部（１６Ｄ）に向かうほど狭く設定しているので、多量の穀桿の押圧によっても搬送螺旋（１６Ａ）の変形を防止することができる。 According to the third aspect of the invention, in addition to the effect of the first or second aspect of the invention, the outer peripheral surface of the scrambling portion (16A) and the non-conveying action surface of the scrambling spiral (16A) are scratched. A plurality of reinforcing plates (16B) arranged at predetermined intervals in the circumferential direction of the portion (16A) are connected, and the circumferential arrangement interval of the reinforcing plates (16B) is set to the front end portion of the screwing spiral (16A). Since the width is set narrower from (16C) toward the rear end (16D), deformation of the conveying spiral (16A) can be prevented even by pressing a large amount of cereal.

請求項４記載の発明によれば、請求項１〜３のいずれか１項に記載の発明による効果に加えて、凹部（６９Ａ）を塞ぐ着脱自在な板（７１）を、隣接する凸部（６８Ａ）の間にわたって設けているので、収穫された種類に応じて扱室（１０）の容積を縮小し、扱歯（１４）の作用を脱穀処理物に十分に与えて脱粒を促進し、穀粒の収穫損失を低減することができる。 According to invention of Claim 4, in addition to the effect by the invention of any one of Claims 1-3, the detachable board (71) which plugs up the recessed part (69A) is made into the adjacent convex part ( 68A), the volume of the handling chamber (10) is reduced according to the harvested type, and the action of the tooth handling (14) is sufficiently applied to the threshing product to promote threshing. Grain harvest loss can be reduced.
