PROBLEM TO BE SOLVED: To prevent winding of stalk around a stalk rake-in device of a harvesting unit of a combine harvester.SOLUTION: The stalk rake-in device 12 behind a raising device 11 is formed of a star wheel 20 to rake in a foot part of a stalk and an engaging raking member 21 positioned above the star wheel and raking and transferring a stalk part of the stalk. A driving shaft 31 of the stalk rake-in device 12 placed between the star wheel 20 and the engaging raking member 21 is surrounded by cylindrical stalk winding prevention members 59, 100, vertical walls 60, 101 are placed behind the stalk winding prevention members 59, 100 and above the star wheel 20, and the vertical walls 60, 101 are provided in a manner extending on the outer circumference of the stalk winding prevention members 59, 100 by plane view and extending from the outer circumference of the stalk winding prevention members 59, 100, crossing a rake-in outer circumference trajectory X of the star wheel 20 and reaching a position behind the star wheel.COPYRIGHT: (C)2012,JPO&INPIT【課題】コンバインの刈取部の穀稈掻込装置周りに穀稈が巻き付くことを防止する。【解決手段】引起装置11後方の稈掻込装置12を穀稈の株元部を掻き込むスターホイル20と、その上方に位置して穀稈の茎部を掻き込み搬送する係止掻込体21で構成し、前記スターホイル20と係止掻込体21との間に設けた穀稈掻込装置12の駆動軸31を筒状の穀稈巻付防止体59,100で囲むと共に、該穀稈巻付防止体59,100の後側でスターホイル20の上部位置に立壁60,101を設け、該立壁60,101を、平面視で穀稈巻付防止体59,100の外周面に連続し、穀稈巻付防止体59,100の外周面部位からスターホイル20の掻き込み外周軌跡Xを横切ってその後方に亘るように配設した。【選択図】図6
