A drop port 22 is provided on one side of the receiving gutter 20 and a finished rice removing gutter 23 is provided below the drop port 22. Reference numeral 24 denotes a finishing rice conveyer horizontally provided on the finishing rice extraction gutter 23.

Reference numeral 25 denotes a paddy rice discharge port, and 26 denotes a paddy rice gutter, and a paddy rice detection sensor 27 is provided between the paddy rice discharge port 25 and the paddy rice gutter 26. The sensor 27 detects the presence or absence of unpolished rice. When the sensor 27 is not detected, it is determined that the entire apparatus is immediately after the start, and when it is detected, it is determined that a certain time has elapsed after the start. Therefore, the installation position of the sensor 27 may be any place that can detect the presence or absence of paddy rice. 28 is a timer switch that operates when the detection sensor 27 is pressed and rotated by the paddy rice, 29 is a paddy rice conveyer horizontally provided on the paddy rice gutter 26, 3
Reference numeral 0 denotes a hopper provided on the side of the first conveyor 14 for supplying the mixed rice from the thrower into the horizontal axis rotary cylinder 19.

When the timer switch 28 is turned off, the supply amount control valve 4 is returned to the average position and is not adjusted. When the timer switch 28 is turned on, the supply amount control valve 4 deviates from the average position and is adjusted to a larger or smaller size. Interlockingly connected to a known adjusting device.

(Operation) Next, the operation will be described.

When restarting the suspended hulling work, or because the paddy varieties are different, when suspending and restarting the work,
The gap between the feeding roll 3 and the supply amount control valve 4 may be abnormally large or may be abnormally small.

According to the present invention, in the above case, the supply amount control valve 4 is always returned to the average position so that the work can be restarted without difficulty. Immediately after supplying the paddy rice to the supply hopper 2 and turning on the main switch of the entire apparatus. Since grain has not reached the detection sensor 27, the timer switch 28 is OFF.

Then, the timer switch 28 and the open / close switches 9, 1
The relationship between 0 and the stop switch 11 is that the timer switch 28
Is OFF, when the operation of the opening / closing switches 9 and 10, for example, the supply amount control valve 4 is wide open, is stopped, the closing switch 10 is pushed by the head of the arm 6
Since it is set to N, the forward / reverse rotation motor 7 is energized to rotate in the forward direction to rotate the arm 6 in the arrow B direction to erect the arm 6 and return it to an intermediate position between the switches 9 and 10. Then, the stop switch 11 is turned on and the forward / reverse rotation motor 7
To stop. On the contrary, when the supply amount control valve 4 is closed and the work is stopped, the open switch 9 is pushed by the head of the arm 6 to turn it on. The arm 6 is rotated in the direction of arrow a so that the arm 6 stands upright and is returned to the average position between the switches 9 and 10. Then, the stop switch 11 is turned on to stop the forward / reverse rotation motor 7.

In this way, the supply amount control valve 4 has the close switch 10 turned on.
Since it is configured to be automatically adjusted to the average position even when the open switch 9 is ON, the drive motor of the hulling roll 12 is not overloaded immediately after the start of work, and the hulling roll 12 is not overloaded. The rice is hulled by the rolls 12 and falls into the wind selection chamber 13, receives the suction wind of the suction blower 16, and the rice grains and the like are discharged from the exhaust pipe, and the mixed rice is fed by the first conveyor 14 and fried by the thrower. The horizontal axis rotation cylinder 19 from the hopper 30
The brown rice that has been supplied inside and settled in the lower layer is scooped up by the jar 18 and sorted on the finishing rice trough 20 to finish the rice spiral 2
No. 1 is sent laterally and dropped from the drop port 22 and the finished rice removal gutter 23
And is taken out by the finishing rice conveyor 24. The unhulled rice remaining in the horizontal axis rotating cylinder 19 is dropped from the unhulled rice discharge port 25 onto the unhulled rice receiving gutter 26, and is taken out by the unhulled rice conveyor 29.

Then, the paddy rice falling from the paddy rice discharge port 25 to the paddy rice receiving trough 26 presses the detection sensor 27 provided in the passage on the way to turn on the timer switch 28. When the timer switch 28 is turned on, the return adjusting function of the supply amount adjusting valve 4 by the switches 9 and 10 is released, and the function is transferred to a conventionally known normal intake valve adjusting mechanism to adjust the normal intake amount. Done.

(Effect) Conventionally known adjustment devices are adjustments in terms of work efficiency. For example, when the amount supplied to the sorting device is too large, the amount is decreased, and when the amount supplied to the sorting device is too small, the amount is increased. It was not suitable for adjustment immediately after the start of work because the adjustment was made so as to exert the best function. Immediately after the start of work, everything is empty, so there is not much and not a little, so that the average amount is supplied and rice is hulled reasonably, and if grain has spread to each part after a certain time, It is a good idea to make adjustments based on efficiency by a known method.

Accordingly, the present invention provides a hulling roll 12, a supply amount control valve 4 for adjusting the amount of paddy rice to be supplied to the hulling roll 12, a forward / reverse motor 7 for opening / closing the supply amount control valve 4, and the adjustment. A closing switch 10 which is turned on when the valve 4 is opened more than the average to turn the motor 7 in the closing direction, and an opening switch which is turned on when the control valve 4 is closed than the average to turn the motor 7 in the opening direction. 9, a stop switch 11 that senses when the control valve 4 is in the average position and stops the motor 7, and a timer switch 28 that is turned on after a certain time has passed after the start of hulling work.
The open / close switches 9 and 10 and the stop switch 11
The motor switch 7 is controlled by the timer switch 2
8 is turned off, and when the timer switch 28 is turned on, a separate control mechanism is used to control the motor 7 so as to control the motor 7. , At the beginning of work,
Since the supply amount control valve 4 can be automatically returned to the average position and the work can be restarted, the work can be performed without an unreasonable load, the grain is not clogged, and after a certain period of time, the normal supply amount control valve 4 is automatically operated. Since the adjustment can be switched to, there is an effect that the hulling efficiency is not lowered.
