特開2010−068752号公報JP 2010-068752 A

特許文献1に記載のコンバインでは、点検開口が小さいため、扱胴のメンテナンス(例えば、扱歯の交換等)を行う際に、点検開口から胴体の内部に手を入れて作業を行うのが容易ではない。   In the combine described in Patent Document 1, since the inspection opening is small, it is easy to put a hand into the body of the trunk from the inspection opening when performing maintenance of the handling cylinder (for example, replacement of tooth handling). is not.

上記状況に鑑み、扱胴のメンテナンスを容易に行うことが可能なコンバインが要望されている。   In view of the above situation, there is a demand for a combine that can easily perform maintenance of the handling cylinder.

本発明の特徴は、
刈取穀稈を扱胴によって脱穀処理する脱穀装置が備えられたコンバインであって、
前記扱胴は、機体前後方向に延びる扱胴軸と、前記扱胴軸に支持されると共に複数の扱歯が外周部に取り付けられる胴体と、を有し、
前記胴体のうち前後中間部を構成する中間胴体部は、前記胴体のうち前記中間胴体部以外の部分に対して着脱可能であることにある。
The feature of the present invention is that
A combine equipped with a threshing device for threshing a harvested cereal meal with a handling cylinder,
The handling cylinder has a handling cylinder shaft extending in the front-rear direction of the machine body, and a trunk that is supported by the handling cylinder axis and has a plurality of handling teeth attached to the outer periphery.
The intermediate body part constituting the front and rear intermediate part of the body is detachable from the body other than the intermediate body part.

本特徴構成によれば、中間胴体部を取り外すことにより、胴体のうち中間胴体部が取り外された箇所に、大きな開口が出現することになる。これにより、扱胴のメンテナンス(例えば、扱歯の交換等)を行う際に、胴体のうち中間胴体部が取り外された箇所から胴体の内部に手を入れて作業を容易に行うことができる。また、胴体のうち中間胴体部が取り外された箇所から胴体の内部に手を入れることにより、前側胴体部及び後側胴体部の夫々に手が届き易い。すなわち、本特徴構成によれば、扱胴のメンテナンスを容易に行うことが可能なコンバインを実現することができる。   According to this characteristic configuration, by removing the intermediate body part, a large opening appears at a position of the body where the intermediate body part is removed. Thereby, when performing maintenance (for example, replacement of tooth handling etc.) of a handling cylinder, a work can be easily performed by putting a hand into the inside of a fuselage from a position where an intermediate trunk part is removed among the trunks. Moreover, by putting a hand into the inside of the fuselage from the location where the intermediate fuselage is removed, it is easy to reach the front and rear fuselage parts. That is, according to this feature configuration, it is possible to realize a combine that can easily perform maintenance of the handling cylinder.

さらに、本発明において、
前記中間胴体部は、前記中間胴体部が前記胴体の周方向に分割された複数の中間胴体部構成部材を有していると好適である。
Furthermore, in the present invention,
It is preferable that the intermediate body part includes a plurality of intermediate body part constituting members in which the intermediate body part is divided in a circumferential direction of the body.

本特徴構成によれば、扱胴の組み立て時に、中間胴体部を複数の中間胴体部構成部材に分けて取り扱うことにより、中間胴体部全体を一体的に取り扱うよりも労力が少なくなる。また、各中間胴体部構成部材の周方向の長さが短くなるため、強度面で有利である。しかも、メンテナンス作業を行う箇所に応じて、中間胴体部を部分的に取り外すことができる。   According to this characteristic configuration, when assembling the handling cylinder, the intermediate body part is handled by dividing it into a plurality of intermediate body part constituting members, so that the labor is less than that of the whole intermediate body part. Moreover, since the length of the circumferential direction of each intermediate body part structural member becomes short, it is advantageous in terms of strength. In addition, the intermediate body part can be partially removed depending on the location where the maintenance work is performed.

さらに、本発明において、
複数の前記中間胴体部構成部材は、同一の部材によって構成され、かつ、前記扱歯の配列が同一であると好適である。
Furthermore, in the present invention,
It is preferable that the plurality of intermediate body part constituting members are constituted by the same member and have the same teeth arrangement.

In addition, when assembling the handling cylinder, the intermediate body part constituting member is not mixed, and the work can be performed efficiently.

さらに、本発明において、
前記胴体は、前記胴体が前後に分割された複数の胴体部を有し、
前記胴体は、前記胴体部として、前側に位置する前側胴体部と、後側に位置する後側胴体部と、前記前側胴体部と前記後側胴体部との間に位置する前記中間胴体部と、を有し、
前記前側胴体部、前記後側胴体部及び前記中間胴体部は、前後方向の長さが略等しいと好適である。
Furthermore, in the present invention,
The body has a plurality of body parts in which the body is divided into front and rear,
The body includes, as the body part, a front body part located on the front side, a rear body part located on the rear side, and the intermediate body part located between the front body part and the rear body part. Have
It is preferable that the front body part, the rear body part, and the intermediate body part have substantially the same length in the front-rear direction.

本特徴構成によれば、扱胴の組み立て時に、胴体を複数の胴体部に分けて取り扱うことにより、胴体全体を一体的に取り扱うよりも労力が少なくなる。また、各胴体部の前後長さが短くなるため、強度面で有利である。しかも、各胴体部の強度を略等しくして、胴体全体における強度の均一化を図ることができる。   According to this characteristic configuration, when assembling the handling cylinder, the handling of the trunk is divided into a plurality of trunk parts, so that labor is reduced compared to handling the entire trunk as a whole. Moreover, since the front-rear length of each body part is shortened, it is advantageous in terms of strength. In addition, the strength of each body portion can be made substantially equal, and the strength of the entire body can be made uniform.

さらに、本発明において、
前記胴体は、前記胴体が前後に分割された複数の胴体部を有し、
