PROBLEM TO BE SOLVED: To provide a general purpose combine in which the grain such as soybeans with high water content can be harvested without being damaged and soiled.SOLUTION: A general purpose combine is provided with a reaping device (3) including a raking reel (9) for raking grain culms in the front side of a vehicle body (2) with a traveling device (1), and is provided with a threshing device (4) where the whole quantity of the reaped grain culms is input in the reaping device (3) and threshed in the upper side of the vehicle body (2). In the inside of a threshing chamber (19) formed on the upper part of the threshing device (4), a threshing cylinder (18) plurally divided in the longitudinal direction is pivotally installed on the same shaft center in a rotatably driven manner, and an outer circumferential part of the threshing cylinder (18) is surrounded by a cylindrical threshing concave (26). Also, the threshing concave (26) comprises a front threshing concave (26a) for surrounding an outer circumferential part of a front threshing cylinder (18a), and a rear threshing concave (26b) for surrounding the outer circumferential part of a rear threshing cylinder (18b). A relative rotation speed of the front threshing concave (26a) and the rear threshing concave (26b) is configured changeably.COPYRIGHT: (C)2015,JPO&INPIT【課題】水分含有量の高い大豆等の穀粒を、損傷および汚損することなく収穫できるものとする。【解決手段】走行装置(1)を備えた車体(2)の前側に、穀稈を掻き込む掻込リール(9)を備えた刈取装置(3)を設け、車体(2)の上側には、刈取装置(3)で刈り取った穀稈の全量を投入して脱穀処理する脱穀装置(4)を設けた汎用コンバインにおいて、脱穀装置(4)の上部に形成した扱室(19)の内部には、前後方向に複数に分割された扱胴(18)を同一軸心上に駆動回転自在に軸架し、扱胴(18)の外周部を円筒状の受網(26)で包囲する。また、受網(26)を、前部扱胴(18a)の外周部を包囲する前部受網(26a)と、後部扱胴(18b)の外周部を包囲する後部受網(26b)から構成し、前部受網(26a)と後部受網(26b)の相対回転速度を変更可能な構成とする。【選択図】 図3
