PROBLEM TO BE SOLVED: To solve the problem that grain culms remaining in a raking part on the side of a tip of a threshing cylinder are mixed into newly reaped grain culms when reaping work of different kinds of grain culms is performed.SOLUTION: A general-purpose combine harvester includes a raking part formed in such a manner that helical blades 24 are wound around a tip part of a threshing cylinder and the periphery thereof is covered. A cleaning hole 51 is formed in a threshing chamber inlet plate 50 that covers sides of the raking part, and the cleaning hole 51 is provided so as to be openable and closable by a cleaning lid 52. In addition, a side surface part of the threshing chamber inlet plate 50 in which the cleaning hole 51 is formed is formed of a plurality of planes formed along the helical blades 24, and the cleaning hole 51 is formed in one of the plurality of planes.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】異なる種類の穀稈の刈取り作業をした際に、扱胴の先端側の掻き込み部に残留した穀稈が新たに刈取った穀稈に混入してしまう。【解決手段】扱胴の先端部にラセン羽根24が巻回され、その周囲が覆われて形成される掻き込み部を有する汎用型コンバインであって、該掻き込み部の側方を覆う扱室入口板50に掃除口51を形成し、かつ該掃除口51を掃除蓋52で開閉自在に設けると共に、前記掃除口51が形成される前記扱室入口板50の側面部は、前記ラセン羽根24に沿って形成される複数の平面から形成され、前記掃除口51は、前記複数の平面のうちの一つに形成される。【選択図】図6
