にしていた。 Generally, the de-rolls of a huller are made of rubbery resin such as hard rubber with appropriate hardness and elasticity, and as a result, the rolls wear out approximately in proportion to the amount of paddy removed. Since the gap between the rolls becomes wider and the peeling performance deteriorates, it is necessary to adjust the length of the gap between the rolls as appropriate during the roll removal process. Conventionally, this has been adjusted by operating the gap adjustment handle at appropriate times to rotate the adjustment rod, and then moving the lever to move the auxiliary roll supported by the lever.

じやすい等の種々の問題を有していた。 However, it is necessary to adjust the gap between derolling by the appropriate amount at the right time while visually checking the dehulling condition of the paddy, so it is not easy to accurately adjust the amount that corresponds to a good dehulling condition, and it is not easy and requires skill. This method has had various problems, such as requiring a lot of work, being troublesome, and being prone to variations in removal.

提供せんとするものである。 The present invention was made in view of the above circumstances, and since the amount of derolling per unit time and the wear amount of derolling are approximately proportional, the gap length of derolling is intermittently reduced by a certain amount depending on the amount of paddy supplied. It is an object of the present invention to provide an automatic derolling gap control device for a rice huller that automatically corrects the derolling gap.

る。 To explain the circuit configuration for controlling the servo motor M according to the supply amount, FIG.
This shows an example, and includes a servo motor M and a power supply 17.
A magnetic switch 18 is inserted between the two, and the supply amount detector 14, the shutter switch 13, and a timer 19 are connected in series to the magnetic switch 18. This timer 19 operates intermittently, and in its operating state it always operates with a constant time width.

す。 In the first embodiment with the above configuration, first, the supply amount adjusting plate 10 is moved to adjust the supply amount to a predetermined value,
Next, when the shutter 8 is opened and release is started, a resistance value corresponding to the opening degree of the supply amount adjusting plate 10 is set in the supply amount detector 14, and the shutter switch 13 is closed. Therefore, the time interval for the intermittent operation of the timer 19 is set by the resistance value of the supply amount detector 14, and the timer 19 operates for a certain period of time with this time interval, thereby causing the magnetic switch 18 to operate intermittently. The drive of the servo motor M is controlled by the closing operation. in this case,
When the supply amount is changed by the supply amount adjustment plate 10, the operation interval of the timer 19 is also changed by the supply amount detector 14, and accordingly, the operation interval of the servo motor M is changed. During operation of this servo motor M, the gears 12, 12a and the joint 6a
The adjusting rod 6 is rotated through the , thereby moving the auxiliary roll 3 to keep the gap length between it and the main roll 2 constant, preferably about 0.8 to 1.0 mm. By the way, since the amount of wear of the roll removal 1 and the amount of removal are approximately proportional, when the supply amount is large as shown in FIGS. 3 and 4, the operation interval of the servo motor M is shortened, and conversely, the supply amount is reduced. If there is less, the operation interval of the servo motor M is controlled to be longer.
In this case, in FIG. 3, to indicates the operating time of the servo motor M, tx 1 to tx o indicate the operating intervals, and FIG. 4 indicates the possible range of interval correction.

動作を得ることができる。 FIG. 5 shows a second embodiment, in which an oscillation circuit 20, a frequency divider 21, a one-shot timer 22, and a non-contact relay 23 are sequentially connected to the supply amount detector 14, and this non-contact relay 23 is inserted between the servo motor M and the power source. Further, the shutter switch 13 is connected to each of the circuits 20, 2.
1 and 22, and the power supply. Then, the oscillation frequency of the oscillation circuit 20 is varied according to the change in the resistance value of the supply amount detector 14, and after being divided by the frequency divider 21, the output signal of this frequency divider 21 is used to determine the supply of paddy. The cycle length, for example, the pulse cycle, of the signal output from the one-shot timer 22 is changed in accordance with the amount, and thereby the drive of the servo motor M is controlled via the non-contact relay 23. This servo motor M
The control operation is similar to that of the previous embodiment, and is as shown in FIGS. 3 and 4. Note that the oscillation circuit 2
