Abstract

PURPOSE: To enable a specified control of an exact husking rate without hindrance even after restarting by having the correction of a roll gap freshly executed from a reference state at the time of restarting the work after paddy sensor off. CONSTITUTION: At the time of husking work, husking roll is adjusted to a roll gap meeting a reference value opening degree set by a setter 63 and the husking work is continued. When the valve opening degree by a valve opening degree sensor 62 detected at every specified interval time changes as compared with that at the time of the previous detection during the husking work when the paddy sensor 60 detecting paddy is on, the differential roll gap for the reference value opening degree is corrected. At the time of on when the paddy sensor 60 does not detect the paddy any more when the paddy in the hopper runs out, the roll gap is returned to the reference roll gap at the reference value opening degree. The correction of the roll gap corresponding to the difference between the detected value after the restarting and the reference value opening degree is executed and the work is restarted when the work is started again by the on of the paddy sensor 60.
