(Problems to be solved by this invention) However, in hulling work, the amount of protrusion per hour is large, that is, the work is highly efficient, or the sorting air volume is adjusted depending on the characteristics of the particles to be depleted. I have something to do. Then, when the air flow rate is changed from a low flow rate to a high flow rate, the load current of the traction motor may change from 5.4A to 6.2A, and 0.8A may change, so if the air volume is adjusted during hulling work, In this connection, the roll gap of the depulling roll may also change. Because of that, I can no longer get the desired removal rate,
The amount of undamaged granules may increase, making it impossible to sort, or the work efficiency may decrease.

Next, the operation will be described. First, when the manual switch (53) is turned “ON” to drive the main electric motor (2), this power is appropriately transmitted through rotating mechanisms of the machine body via a transmission mechanism (not shown). It is transmitted to and makes it rotate. Subsequently, when the operator turns the adjustment shaft (41) in the direction of the arrow (b), the funnel opening / closing valve (38) also turns downward and stops at the set position (for example, the position of (V 4 )). The amount of grains corresponding to this opening is delivered to the removing roll (1) side by the delivering body (35) and receives the removing action, and then falls to the sliding rice gutter (10) side. Then, during this time, the suction air sucked by the rotating suction fan (9) is subjected to a wind-selection action to separate and sort foreign matter such as rice husks and dust. Then, this mixed grain is sorted into a predetermined grain (for example, extraction of brown rice) by a mixed rice sorting device (8).

In such hulling work, the measured load current (V 4 ) of the main motor (2) detected by the current transformer (50) is rectified by the rectifier circuit (49) and then amplified by the amplifier circuit (48). Then, it is smoothed by the smoothing circuit (47) and then input to the control circuit (46). In addition, this control circuit (46),
Since the set value (corresponding to the set load current O 3 ) corresponding to the preset valve opening (V 4 ) is input, the set place and the measured load current are compared and both values become approximately equal. A drive command signal is output to the forward rotation drive circuit (51) or the reverse rotation drive circuit (52), and the geared motor (30) is rotated in the forward or reverse direction to automatically adjust the roll gap between wide and narrow.

However, there may be a case where a large amount of dust or straw dust is mixed in the paddy, or the number of rotations of the suction fan (9) is increased when switching to high efficiency work. For example, when setting the adjustment arm (19) from "weak" to "4" position,
Since the connecting rod (16) is also pulled in the direction of the arrow (a) and the tension pulley (12) and the arm (14) are pivoted upward about the pivotal portion to tension the belt (54), this is related to this. As the pitch circle diameter of the split pulley (13) becomes smaller,
Increase the rotation speed of the suction fan (9). Therefore, the suction air selection capability of the suction fan (9) which rotates at high speed is also enhanced, and the foreign matter sorting and discharging performance can be improved.

However, at this time, if the suction rotation speed is increased, the load current increases. Therefore, if the set control current is the same, the roll gap is "opened". As a result, the preset removal rate cannot be obtained, the amount of paddy increases, and the sorting work efficiency decreases or the work becomes impossible. On the other hand, in this embodiment, the load current P 1 for which the air volume adjustment is set to “4” and the set load current (control current) for the valve opening (V 4 ).
Is added by the adder circuit (45), and this added current becomes the reference control current, so even if the load current increases by adjusting the air volume, the control current at the valve opening (V 4 ) must be secured. Therefore, the roll gap is not excessively opened and the removal rate is not lowered.

In addition, in the embodiment, the case where the control current (O 4 ) is constant at the valve opening (V 4 ) is explained, but this current (O 4 )
If the removal rate is 85% at the time of, it is possible to easily configure the control current by adjusting the control current to high or low so that the removal rate is 85% or more. . Then, the load current P 1 is added to the adjusted control current.
It suffices to use a current obtained by adding as a reference control current.
