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、製作作業の負担を軽減するために、機体の前後方向に延伸する扱同軸の前端部、中間部、及び後端部に固着された支持部材に、前後方向に扱歯を立設した桟部材を架設した扱胴が提案されている（特許文献１参照）。 Conventionally, in order to reduce the burden of the production work, a bar with standing teeth in the front-rear direction on support members fixed to the front end part, the intermediate part, and the rear end part of the handling coaxial line extending in the front-rear direction of the machine body. A handling cylinder in which members are installed has been proposed (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、前後方向に扱歯を立設した桟部材を架設し、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提案されている（特許文献２参照）。 In addition, a crosspiece member in which teeth are erected in the front-rear direction at the apex of a substantially hexagonal support member fixed to the front end part, the intermediate part, and the rear end part of the handle cylinder shaft extending in the front-rear direction of the machine body.

しかし、特許文献１記載の発明における扱胴は、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。
また、特許文献２記載の発明における扱胴は、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。また、周方向に隣接して配置される桟部材の扱歯の前後方向での間隔が等しいために、特に、扱胴の上流側において、収穫された丈の長い穀桿が扱歯に絡み、脱粒性能を低下させ、また、後方への搬送性能を低下させる虞があった。 However, in the handling cylinder according to the invention described in Patent Document 1, there is a possibility that the cereal straw supplied to the handling chamber is entangled with the crosspiece member, and the degranulation performance and the backward conveyance performance are deteriorated.
Moreover, since the cross-sectional shape of the trunk | drum is hexagonal shape in the invention described in patent document 2, the intensity | strength of the plane part (shielding board) between vertex parts is low, and a lot of cereals are supplied to a handling chamber. 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. In addition, since the interval in the front-rear direction of the tooth handling of the crosspiece member arranged adjacent to the circumferential direction is equal, especially on the upstream side of the handling cylinder, the harvested long cereal entangled with the tooth handling, There is a possibility that the degranulation performance is lowered and the conveyance performance to the rear is lowered.

It inclines again downward from the intermediate part of the substantially width direction so that the space | interval of the outer peripheral surface of a part and the handling cylinder 11 may be expanded.

後方への穀稈の搬送を効率的に行うために、回転レバー４６を揺動させることによって送塵ガイド４２の傾斜角度を変更することができる。
各送塵ガイド４２は、送塵ガイド４２の幅方向の略中心に設けられた軸４３に回転自在に支持されており、各送塵ガイド４２の左側上部は、前後に延伸している連結レバー４４によって相互に連結されている。連結レバー４４の前部は、軸４５の下部に溶接等によって固着され、軸４５は、扱胴カバー４０の外面に設けられた支持部材４７に回転自在に支持され、軸４５の上部には、連結レバー４４に対して略直交方向に延伸する回転レバー４６が溶接等によって固着されている。なお、後方への搬送される穀稈の押圧によって送塵ガイド４２の傾斜角度の変動を防止するために、軸４３は、送塵ガイド４２の幅方向の中心よりも左側（扱胴１１の回転方向側）に配置するのが好適である。 The tilt angle of the dust feed guide 42 can be changed by swinging the rotation lever 46 in order to efficiently carry the cereals backward.
Each dust feed guide 42 is rotatably supported by a shaft 43 provided substantially at the center in the width direction of the dust feed guide 42, and the upper left portion of each dust feed guide 42 is a connecting lever extending in the front-rear direction. 44 are connected to each other. The front portion of the connecting lever 44 is fixed to the lower portion of the shaft 45 by welding or the like, and the shaft 45 is rotatably supported by a support member 47 provided on the outer surface of the barrel cover 40. A rotating lever 46 extending in a direction substantially orthogonal to the connecting lever 44 is fixed by welding or the like. In addition, in order to prevent the fluctuation of the inclination angle of the dust feeding guide 42 due to the pressing of the cereals conveyed rearward, the shaft 43 is on the left side (the rotation of the handling cylinder 11) from the center in the width direction of the dust feeding guide 42. It is preferable to arrange it on the direction side.
