PROBLEM TO BE SOLVED: To provide a grain adjuster capable of properly maintaining the hulling function of a hulling roller 30, by improving de-Relly-pressure adjustment operability of the hulling roller 30.SOLUTION: The grain adjuster comprises a pair of hulling rollers 30 driven via a belt transmission mechanism 29 and a hulling link mechanism 92 for contacting-separating another one hulling roller 30 to one hulling roller 30, and finished as unpolished rice by removing chaff from unhulled rice by the respective hulling rollers 30, and the hulling link mechanism 92 is connected with a tension adjusting member 119 of the belt transmission mechanism 29, and is constituted so that tension of the belt transmission mechanism 29 can be adjusted by de-Relly-pressure adjusting operation of the hulling link mechanism 92. |
