Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention controls a hulling / sorting device which performs a hulling / sorting of dried paddy, and a particle size screening for packing for shipping. It concerns the mechanism.

(B) Prior art Conventionally, a plant for hulling and sorting dried rice brought by many farmers is known.

Further, in a conventional plant, a technology related to a control mechanism of a hulling / sorting device that controls opening and closing of a tank provided in an upper part of a hulling wind sorter or a sorter and shutters of respective parts is also known.

(C) Problems to be Solved by the Invention The present invention is based on the idea that the entire hulling / sorting apparatus constitutes one system as a whole, and that the entire apparatus constituting each part operates smoothly, and there is no excess or shortage of shell particles flowing between them, and the optimum load is always maintained. And a single system control mechanism for interlocking the shutters and valves of each section so that the sheet is conveyed in the state described above.

In particular, before the opening and closing control of the roll tank shutter and the take-off roll, the opening and closing control of the supply control valve is first performed, and when the roll tank shutter is opened, the supply control valve is always controlled by the supply control valve. In addition, it is configured so that excessive and minimum paddy before control does not flow to the decapture roll.

In addition, when the roll tank shutter at the bottom of the roll tank is opened, the gap between the entrainment rolls is configured to be closed immediately, and even though the roll tank shutter is open, the entrapment roll is opened. This eliminates the disadvantage that the unhulled paddy flows and overloads the sorting machine.

In addition, if the amount in the sorter tank is small, the operation of the sorter is stopped, and if the amount in the sorter tank is excessive, the supply control valve is closed, and the removal roll is opened, causing waste. It is configured to eliminate a large amount of power consumption.

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

First, the roll tank shutter SV3 and the decapture roll 7,7
Before the opening / closing control of the supply control valve 3, the opening / closing control of the supply control valve 3 is performed first. Therefore, when the roll tank shutter SV3 is opened, the amount of the supply control valve 3 is always controlled. The paddy did not flow to the decapture rolls 7,7.

Second, when the roll tank shutter SV3 at the lower part of the roll tank 1 is opened, the gap between the rolls 7,7 is immediately closed.
Despatch roll with paddy released despite SV3 opening 7,7
Thus, the problem that the unhulled paddy flows and overloads the sorting machine 6 has been eliminated.

Third, when the amount in the sorter tank 2 is small, the operation of the sorter 6 is stopped, and when the amount in the sorter tank 2 is excessive, the supply control valve 3 is closed, and By opening 7,7, unnecessary power consumption can be eliminated.
