Then, paddy tank 2
The paddy inside is opened, the paddy supply amount is adjusted by the paddy supply amount adjustment valve 19 through the paddy supply path 4, and the paddy is removed by a pair of derolls 3.

Further, when finishing or interrupting the hulling operation, if the knob 49 is turned to the "closed" display side, the operating rod 15 exerts a pushing action on the opening/closing plate 13 to close the paddy supply path 4.

Therefore, during the above-mentioned hulling work, the paddy tank 2
Depending on conditions such as the type of paddy to be supplied and the degree of drying, there may be cases where the amount of paddy supplied to the derolling section 3 increases even though the paddy supply amount control valve 19 is opened at the same degree. When the amount of mixed rice that is returned to the pot-hole rotary sorting unit C under the influence of the sorting action and subjected to the re-sorting action increases, this mixed rice flows down on the return plate 12 and becomes the mixed rice that is removed by the above-mentioned removing rolls 3. It is combined with the 6 coarse sorting section C1 by the thrower 9, and lifted up to the storage tank 5 by the screw conveyor.
However, as the amount of mixed rice lifted into the storage tank 5 increases in this way, the amount of retained rice in the storage tank 5 increases and overflows from the reduction cylinder 11.
This overflowing mixed rice acts on the sensing valve 32 provided in the flow rate sensing box 10, causing the sensing valve 32 to move towards the shaft 3.
Using 1 as a fulcrum, swing downward and move the armrest 3.
7. Interlocking plate 36, interlocking rod 38, interlocking plate 33, interlocking rod 3
The operating shaft 20 is transmitted to the arm rod 30 via the adjustment ring 2
The paddy supply amount control valve 19 is rotated in an unregulated direction by the contact between the lower edge 27a of the control pin 29 and the control pin 29.
The amount of paddy supplied to the derolling tank 3 is reduced by reducing the opening degree of the valve, and when the mixed rice no longer overflows from the storage tank 5, the sensing valve 32 is returned to its original state by a bullet (not shown), and at the same time, the adjustment pin is closed. 29 comes into contact with the lower edge 27a of the adjusting metal 27, and the paddy supply amount regulating valve 19 maintains its original opening degree, and the amount of paddy supplied to the derolling member 3 is automatically adjusted.

(g) Effects of the invention As detailed above, the present invention provides the paddy supply adjustment device in the head of the hulling machine described at the beginning, in which the operating rod for opening and closing the opening/closing plate and the opening degree of the paddy supply amount adjustment valve are used. An adjustment rod for adjusting the movement is extended to and adjacent to the operation side of the aircraft, and the operation rod is shaped like a crank and the upper end on the opposite side to the operation side engages with the push/pull side of the opening/closing plate to rotate the operation rod. The opening/closing plate is opened and closed by operation, and the adjustment rod is located above the operating shaft, is horizontally mounted in parallel, and has a threaded part on the side opposite to the operating side. The upper edge of the inclined inverted triangular adjustment piece is fixed so that the adjustment piece hangs down in front of the operating shaft and can be moved in the width direction of the machine by rotating the adjusting rod. An adjustment pin is protruded toward the front, and the adjustment pin is urged to come into contact with the lower edge of the adjustment rod through a bullet, and by rotating the adjustment rod, the amount of paddy supplied is controlled through the adjustment metal and the adjustment pin. Since it is characterized by having a configuration in which the control valve is adjusted, the following effects can be achieved.

That is, (a) When operating the opening/closing plate or the paddy supply amount control valve as in the conventional system, there is no need to reach out from the operating side of the machine and perform each operation on the operating side very simply and easily. The operation can be carried out accurately, and since the operating lever and the adjusting lever that direct the opening/closing plate and the paddy supply amount regulating valve are located next to each other, the operation can be carried out very conveniently.

(b) Moreover, since it is located next to the operation side, the display for opening and closing the opening plate and adjusting the opening of the paddy supply amount control valve is easy to see and can be operated accurately and properly, so there is no need to worry about erroneous operation. .

(c) Furthermore, since the opening/closing plate and the paddy supply amount control valve were operated by the operator side of the machine using the above-mentioned means, the operation became easy and accurate. It is.

In addition, as shown in the example, even if the opening degree of the paddy supply amount control valve remains unchanged, the amount of paddy supplied to the de-rolling increases depending on the paddy conditions, or the effect of sorting action between brown rice and paddy increases. If the amount of mixed rice to be re-sorted increases due to the amount of mixed rice that needs to be re-sorted, the rice hulling operation can be stabilized by sensing this and automatically reducing the opening of the paddy supply amount control valve to reduce the amount of paddy supplied. It becomes more practical.
