(effect) Next, we will discuss the effect.

To explain with reference to the flowchart in FIG. 3, before the work, the lower limit level switch 18 is not sensing paddy, so the motor 6 is energized, the pinion 8 is rotated counterclockwise, and the tensioning shutter 4 is turned on. is opened, and the unhulled rice in the loading hopper 3 is allowed to flow into the elevator 1.

At this time, the moisture content of the unhulled rice in the stake hopper 3 is determined by the moisture meter 35.
If the moisture content is higher than expected, the answer is No, so the sub roll 22 is released and the lining shutter 4 and roll upper shutter 12 are closed.

If the moisture content is below the set value, the answer is YES, so open the shutter 4 and raise and lower the supply! Let it flow into j11,
The grains are fried by the packet conveyor 2 and stored in the supply tank 9.

(In Fig. 2, before the work, the lower limit level switch 18 in the supply tank 9 is not sensing paddy, so the solenoid of the staking shutter 4 is energized and the staking hopper 3
The unhulled rice inside is dropped onto the supply conveyor 26, the motor 27 is energized to rotate the supply conveyor 26, the unhulled rice inside the stake hopper 3 is flowed into the elevator 1, and the unhulled rice is fried by the packet conveyor, and the unhulled rice is sent to the supply tank. Store within 9. In this case, the moisture content of the unhulled rice is measured by a moisture meter 35, and if the moisture content of the unhulled rice exceeds a set value, the lining shutter 4 and roll upper shutter 12 are closed, as in the case of FIG. ) When the paddy stored in the supply tank 9 reaches the upper limit level switch 17, the motor 14 is energized to rotate the pinion 16 clockwise, the roll upper shutter 12 is opened, and the paddy falls from the drop opening 11 and is repeatedly dumped. It is supplied to a main roll 21 and an auxiliary roll 22 by a loading roll 20. At the same time, the motor 6 is energized, the pinion 8 is rotated clockwise, and the tensioning shutter 4 is closed.

(In FIG. 3, when the paddy stored in the supply tank 9 reaches the upper limit level switch 17, the solenoid of the tensioning shutter 4 is energized to close the tensioning shutter 4, and the motor 27 is energized to supply the (The conveyor 26 is stopped.) At this time, the paddy sensing root 24 detects the dropping of paddy, so the motor 23 is energized, and the sub roll 22 is brought closer to the main roll 21 to remove the paddy.

(Effects) As mentioned above, the conventional huller is equipped with a level switch in the huller tank, and the switch and the roll upper shutter are linked to open the roll upper shutter when there is paddy in the supply tank. The structure is such that a paddy sensing plate detects the dropping of paddy, moves the sub roll closer to the main roll, and when the paddy sensor stops detecting paddy, a motor moves the sub roll away from the main roll. Since the hulling process was carried out without regard to the moisture content of the rice, there was a problem in that even rice with a high moisture content that was impossible to hull was forced to be hulled.

However, in the present invention, the moisture content of unhulled rice is measured by a moisture meter 35 installed in the supply path of the hulling device, and when the moisture content of the unhulled rice exceeds a set value, the paddy supply is interlocked and opened to transfer the unhulled rice to the hulling section 25.

The moisture content of the unhulled rice is measured by the moisture meter 36, and the moisture meter 35 or the moisture meter 35 and the supply adjustment device are interlocked and connected, and when the moisture content of the paddy is higher than a set value, the paddy supply is interlocked and opened to send the rice to the hulling section 25.
This is an automatic feeding device in a hulling machine that supplies paddy to the hopper 3 and stops the hulling operation by cutting off the supply of paddy when the moisture content of the paddy is below a set value. The moisture content is measured by the moisture meter 35, and if the moisture content is higher than expected, the result is No, so the sub roll 22 is released, the lining shutter 4 and the roll upper shutter 12 are closed,
If the moisture content is below the set value, the answer is YES, so the lining shutter 4 is opened, the grain is flowed into the supply elevator @1, the grain is fried by the packet conveyor 2, and the grain is stored in the supply tank 9 and hulled. To prevent the defect of forcibly hulling unhulled rice.
