According to this feature configuration, when assembling the handling body, by handling the body separately in a plurality of body portions, less labor is required than when the entire body is handled integrally. At that time, by connecting the front and rear adjacent body portions with the front and rear connecting members, it is not necessary to overlap the front and rear adjacent body portions, and the outer peripheral surface of the front fuselage portion and the outer peripheral surface of the rear fuselage portion. It is possible to easily connect the body portions adjacent to each other in the front-rear direction so that the two bodies are flush with each other. Moreover, the front-rear connecting member does not come into contact with the grain culm in the handling chamber to interfere with the threshing process, and the front-rear connecting member does not wear due to contact with the grain culm in the handling chamber. Further, since the front-rear length of each body portion is shortened, it is advantageous in terms of strength. That is, according to this feature configuration, it is possible to realize a threshing device having an excellent assembling property and an advantageous handling cylinder in terms of strength.
According to this feature configuration, the front-rear intermediate portion of the fuselage is supported by the handling barrel shaft via the radial connecting member, which is advantageous in terms of strength.

さらに、本発明において、
前記前後連結部材は、前記胴体の内周面に沿って設けられ、
前記規制部は、前記前後連結部材のうち前記胴体の内周面に対向する部分から前記胴体の径方向の外側に突出する突起であると好適である。 Further, in the present invention
The front-rear connecting member is provided along the inner peripheral surface of the fuselage.
It is preferable that the restricting portion is a protrusion protruding outward in the radial direction of the body from a portion of the front-rear connecting member facing the inner peripheral surface of the body.

本特徴構成によれば、突起を胴体部の開口縁部に宛がうだけで、前後連結部材が胴体部の開口縁部から胴体部の内部に入り込み過ぎるのを確実に防止することができる。 According to this feature configuration, it is possible to reliably prevent the front-rear connecting member from entering the inside of the body portion too much from the opening edge portion of the body portion only by applying the protrusion to the opening edge portion of the body portion.

さらに、本発明において、
前記突起は、前記胴体の外周面よりも前記径方向の外側に突出していないと好適である。 Further, in the present invention
It is preferable that the protrusion does not protrude outward in the radial direction from the outer peripheral surface of the body.

仮に、突起が胴体の外周面よりも胴体の径方向の外側に突出していると、扱室内の穀稈が突起に引っ掛かって脱穀処理の妨げとなり易い。しかし、本特徴構成によれば、脱穀処理の妨げとならないように、扱室内の穀稈が突起に引っ掛かり難くすることができる。 If the protrusion protrudes outward in the radial direction of the body from the outer peripheral surface of the body, the grain culm in the handling chamber is likely to be caught by the protrusion and hinder the threshing process. However, according to this feature configuration, it is possible to prevent the culm in the handling chamber from being caught by the protrusions so as not to interfere with the threshing process.
