Set the paddy supply control valve 41 of the paddy section 1 to a predetermined opening (for example, 10
mm) is set to the initial opening and hulling work is started. Then, after a predetermined time, the supply amount assumption switch 40
Based on the paddy efficiency setting, the adjustment command signal is sent to the paddy supply adjusting motor 42, and the paddy supply adjusting valve 41 is changed and adjusted to the set efficiency opening. This supply amount assumption switch 4
In connection with the hull efficiency setting of 0, the control reference current value of the load current value control for hull roll clearance adjustment is changed. Next, the gap adjustment control of the hulling rolls 7 and 7 is performed based on the load current value reference, the load current control reference value and the detected load current value are compared, and when the load current control reference value is higher than the detected load current value (or , (When it is low), an open (or close) command signal is output to the roll gap adjusting motor 45 to adjust the gap between the hulling rolls 7 and 7 to a predetermined amount (open or close side), and the detection load. The return of the current value to the control reference value is achieved, and if the detected load current value is within the range of the reference load current value, the control command signal is not output, while maintaining the hulling roll gap as it is, Hulling work is performed while maintaining the set removal rate.

Instead of this load current value control, the dehulling rate gap (not shown) is compared with the detected dehulling rate and the control reference dehulling rate, and the hull roll gap is based on the heave rate. May be adjusted. During the automatic control of the gap between the hulling rolls described above, the load current value detected by the load current sensor 38 and the paddy supply valve opening sensor 42 are detected.
The detected opening degree of the paddy supply control valve 41 in a is calculated by the calculation control unit 35.
It is stored in a storage device inside and is compared with an overload reference current value at which a breaker (not shown) in the memory falls.
When the detected load current value is lower than the overload reference current value by a predetermined value or less and the possibility of the breaker dropping is low, the adjustment control based on the load current value reference is continued as it is, When the value is within a predetermined value with respect to the overload reference current value and there is a high possibility that the breaker will drop, an open command signal is output and the gap between the hulling rolls 7, 7 is opened by a predetermined amount in the opening direction. The load current control reference value is lowered by the decrease correction amount and the hulling rolls 7, 7 are adjusted.
The automatic gap adjustment is done. Therefore, while hulling work,
The hulling work can be performed efficiently while preventing the falling off. Note that, instead of the decrease correction of the load current reference value, the opening degree of the paddy supply control valve 41 is corrected to the closed side by a predetermined amount,
The hulling efficiency set by the supply amount assumption switch 40 may be lowered to continue the automatic control (FIG. 9 shows this control flow).
