PROBLEM TO BE SOLVED: To provide a waste straw processor for a combine harvester which is capable of efficiently dropping and collecting remaining rice grains within bundles of waste straw stalks discharged from a threshing part with a simple structure.SOLUTION: The waste straw processor for a combine harvester includes a grain stalk conveying device adjacent to the rear end of the threshing part (12) formed of a feed chain (13) for holding and conveying the root side of fed harvested grain stalks and a threshing cylinder (69) for rotationally threshing the harvested grain stalks. The grain stalk conveying device continuously conveys the root side of the grain stalks from the feed chain (13) to the rear end of a machine body. The grain stalk conveying device is configured to hold and convey the grain stalks between two conveying devices (14a and 14b) disposed vertically opposite manner to perform conveying operation. A conveying speed difference is set between the conveying devices.COPYRIGHT: (C)2012,JPO&INPIT【課題】脱穀部から排出された排藁穀稈の束内の残留籾粒を簡易な構成によって効率よく落下回収することができるコンバインの排藁処理装置を提供する。【解決手段】コンバインの排藁処理装置は、供給された刈取穀稈の株元側を挟持搬送するフィードチェン(13)とその刈取穀稈を回転脱穀する扱胴(69)とからなる脱穀部(12)の後端に隣接し、上記フィードチェン(13)から穀稈の株元側を引継いで機体後端部に搬送する穀稈搬送装置を備えて構成され、上記穀稈搬送装置は、上下に対向して搬送動作する2つの搬送装置(14a,14b)によって間に穀稈を挟持搬送可能に構成するとともに、両搬送速度間に差を設けたものである。【選択図】図1
