PROBLEM TO BE SOLVED: To prevent grains from scattering from a gap between a guide and an inlet plate.SOLUTION: The combine harvester includes: a threshing part (3) for introducing grain stalks conveyed from a front processing part (2) through a supply port (13) and threshing the introduced grains the entrance plate (17) extending forward from the lower edge of the supply port (13) for guiding the grain stalks to the supply port (13) and the guide (20) disposed from the terminal end of conveyance of the front processing part (2) to the upper surface of the entrance plate (17) and guiding the grain stalks onto the entrance plate (17). The combine harvester also has a plugging member (21) at a front position on the ear-tip side of the supply port (13) for preventing the grains from being blown out of the gap (X) formed between the guide (20) and the entrance plate (17). The plugging member (21) is composed of a flexible plate-shaped body. The base end (21a) of the plugging member is attached and supported on a threshing machine body (F) side, and the front end (21b) of the plugging member is movably cantilevered by the contact with the guide (20). The front end (21b) of the plugging member is elongated to enter under the guide (20).COPYRIGHT: (C)2012,JPO&INPIT【課題】案内体と入口板との間の隙間から穀粒が飛散することを防ぐ。【解決手段】前処理部(2)から搬送される穀稈を供給口(13)から導入して脱穀する脱穀部(3)と、供給口(13)の下縁部から前方に延出し、穀稈を供給口(13)に導く入口板(17)と、前処理部(2)の搬送終端部から入口板(17)の上面部に亘って設けられ、穀稈を入口板(17)上へ導く案内体(20)と、を備えるコンバインにおいて、供給口(13)の穂先側前方位置に、案内体(20)と入口板(17)との間に形成される隙間(X)からの穀粒の吹き出しを防止する塞ぎ部材(21)を設け、塞ぎ部材(21)は可撓性を有する板状体で構成し、その基端部(21a)を脱穀機体(F)側に取付支持し、先端部(21b)が案内体(20)との接触によって移動可能に片持ち状に設けると共に、塞ぎ部材(21)の先端部(21b)を長く延出して案内体(20)の下に入り込ませた。【選択図】図4
