Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automatic adjustment device for a pot-hole type different grain sorting device in each huller.

(Prior Art) Conventionally, some rice hulling devices are equipped with a pot-hole type different grain sorting device. This device supplies mixed rice of different types to one end side of a rotating cylinder that has numerous potholes formed on its inner surface, scoops up the lower layer of finished rice (brown rice) through the potholes, and places it inside the rotating cylinder once. The finished rice is taken out into the receiving trough and separated from the unhulled rice left in the rotating cylinder.

In order to perform good sorting of mixed rice by this grain sorting device 2, it is necessary to make sure that there is no excess or deficiency of grains fed into the rotary cylinder. A detection sensor is installed to detect the thickness of the flow stack, and the sensor is connected to a feeding control valve that adjusts the amount of unhulled rice supplied to the huller. The valve is rotated in the direction of closing the valve, and when the opposite is the case, the control valve is rotated in the direction of opening.
The amount of grain fed into the rotating cylinder was kept constant.

However, if the above-mentioned structure is adopted for the hulling device, the purpose of keeping the amount of grain supplied into the rotating cylinder constant is solved; however,
If the dehulling rate at the hulling section changes, the mixed rice will not be sorted properly. In other words, if the actual dehulling rate is higher than the set dehulling rate, even if there is no change in the amount of grains fed into the rotating cylinder, the amount of brown rice will be larger than the setting, and sometimes it will not be able to be sorted in the rotating cylinder. The unhulled rice is discharged together with the reduced paddy rice and returned to the hulling section, which may cause the unhulled rice to be washed twice.Also, when the dehulling rate is low, the amount of unhulled rice in the rotary cylinder increases and 1
A large amount of unhulled rice would accumulate in the rotating cylinder, and the rotating cylinder would sometimes become unsortable due to a so-called puncture phenomenon.

Thus, a dropping passage 45 for the reduced unhulled rice is formed at one end 18 of the rotary cylinder 14, and a reduced unhulled rice receiving trough 46 is formed below the passage 45. A brown rice sensor 47 is provided in the falling passage 45 to detect the brown rice discharged from the rotary tube 14 together with the reduced unhulled rice. The sensor 47 is a comparator 48

The motor 34 is rotated in the normal direction to draw the top 36 in the direction of arrow A in FIG. 7, and the arm 37 is rotated. Then, the shaft 32 rotates, and the transmission is transmitted in the order of arm 39 → rod 40 → bell crank 41 → tambuckle 42 → arm 43 → shaft 44, and the refill control valve 4 is rotated in the closing direction. 50
is a paddy rice spiral installed in the reduced paddy rice receiving trough 46.

51 is a motor that drives the hulling roll 5, and a belt 5 is provided between the hulling roll 5 and the motor 5.
Multiply by 2 and turn. The comparator 48 is connected to the motor 51, and the dehulling rate of grains is determined from the load current value of the motor 51 by the comparator 48. 53 is a thrower provided on one side of the unhulled rice spiral 50.

(effect) Next, we will discuss the effect.

When the unhulled rice is supplied to the supply hopper 2 of the hulling section 1, the loading of the unhulled rice is adjusted by the loading adjustment valve 4, and the unhulled rice is transferred to the hulling roll 5.
5, the rice is hulled, and falls into the wind sorting section 6.The rice husks are discharged from the wind exhaust tube 8 by the suction wind of the suction blower 7, and the immature rice falls into the immature rice receiving trough 12, where it is transferred to the immature rice conveyor lO. The mixed rice falls into the mixed rice receiving gutter 11,
The mixed rice is taken out by the mixed rice conveyor 9 and fried by the thrower 27 to the mixed rice supply/recovery gutter 25 of the different grain sorting gB13.
Since the 0-rotation tube 14, which is transferred to the input port 28 by the mixed rice supply spiral 26 and fed into the horizontal rotation tube 14, is rotating clockwise in FIG. 2
2, the brown rice in the lower layer is pulled up through the pot hole 15 and taken out to the finished rice receiving trough 16, transferred to one end side 18 by the finished rice conveyor 17, and dropped to the finished rice takeout [20] from the drop port 19. The finished rice is conveyed sideways by the finished rice take-out conveyor 21 and taken out of the machine.

The mixed rice is sorted onto the supply/recovery gutter 25 and transferred to the rotating cylinder 14 again.
The unhulled rice moves to one end side 18 without being sorted, falls from the falling passage 45 onto the reduced unhulled rice receiving trough 46, is conveyed to the thrower 53 by the unhulled rice spiral 50, and is transferred to the thrower 53.
is returned to hopper 2 for reprocessing.

Therefore, when the number of grains supplied into the horizontal shaft rotating cylinder 14 increases or decreases, and the thickness of the flow layer 29 formed inside the rotating cylinder 14 changes, the detection sensor 30 rotates accordingly. Shaft sleeve 31 → Arm 33 → Motor 34 → Rotating screw shaft 35 → Top 36 → Bin 38 → Arm 37 → Shaft 32 → Arm 39 → Rod 40 → Bell crank 41 → Tongue buckle 42 → Arm 43 → @44 and transmission When there are many grains, the feeding control valve 4 is rotated in the direction to close, and when there are few grains, the feeding control valve 4 is rotated in the direction to open. For this reason, when the ratio between the position of the detection sensor 30 and the opening degree of the feeding adjustment valve 4 is set by the tongue buckle 42, the grains supplied into the rotary cylinder 14 are rotated by 314% at this ratio. It will be supplied within the country.

Therefore, if the dehulling rate in the hulling section 1 changes, the amount of brown rice supplied into the rotary cylinder 14 naturally changes. That is, when the dehulling rate is high, even if the grains supplied into the one-rotation cylinder 14 are controlled to be constant, the amount of brown rice supplied increases, and when the dehulling rate is low, the amount of unhulled rice supplied increases. .

Therefore, when brown rice that has a high dehulling rate and exceeds the brown rice sorting capacity of the single-rotation cylinder 14 is supplied into the rotary cylinder 14, the single-rotation cylinder 14
Brown rice will be mixed into the unhulled rice that is discharged as reduced unhulled rice, and the brown rice will be rubbed twice.
In the present invention, when brown rice is mixed into the unhulled rice falling down the dropping passage 45, the brown rice sensor 47 detects the brown rice.

The values are compared by a comparator 48, and a control circuit 49 controls the motor 34 to rotate the rotating screw shaft 35 in the forward direction to draw the top 36 in the direction of arrow A. Then, as shown in FIGS. 7 and 8, the arm 37 and the detection sensor 30
The angle formed by this expands from the initial setting angle θ to the angle α.

At this time, since the detection sensor 30 is in contact with the flow stack 29, only the arm 37 side rotates, and the feed control valve 4 closes by the amount of rotation of the motor 34 as described above. 30 and the interlocking ratio of the feed-in control valve 4 can be automatically changed to reduce the grain supply amount.

Furthermore, when the dehulling rate becomes low, the amount of unhulled rice supplied into the rotary cylinder 14 increases, and a large amount of unhulled rice remains in the rotary cylinder 14, which may cause a so-called puncture phenomenon. Therefore, even when the dehulling rate changes to a low value, the number of grains must be reduced in the same way as described above. Therefore, in the present invention, a change in the dehulling rate is detected by measuring the load current value of the motor 51 driving the hulling roll 5 using the comparator 48, and when the dehulling rate becomes low.

The control circuit 49 causes the motor 34 to rotate in the forward direction, and similarly to the above, the interlocking ratio between the detection sensor 30 and the feed-in control valve 4 is automatically changed so as to reduce the grain supply amount.

(Effects) Conventionally, some rice hulling equipment is equipped with a pot-hole type mixed grain sorting device, and this device separates rice mixed with different kinds into one end of a rotating cylinder with numerous pot holes formed on the inner surface. The lower layer of finished rice is scooped up through the pot hole, taken out into a finished rice receiving trough provided in the rotating cylinder, and separated from the unhulled rice left in the rotating cylinder. In order for this grain sorting device to perform good sorting of mixed rice of different types, it is necessary to ensure that there is no excess or shortage of grains fed into the rotating cylinder. A detection sensor that detects the thickness of the flow layer is installed, and this sensor and a feeding control valve that adjusts the amount of unhulled rice supplied to the hulling section are connected to each other when the flow layer is thick and there are many grains. The feed control valve was rotated in the closing direction, and in the opposite direction, the feed control valve was rotated in the open direction to maintain a constant amount of grain fed into the rotating cylinder.

However, if the above-mentioned structure is adopted for the hulling device, the purpose of keeping the amount of grain supplied into the rotating cylinder constant is solved; however,
If the dehulling rate at the hulling section changes, the mixed rice will not be sorted properly.

However, in the present invention, a pot-hole type dissimilar grain selection section 13 having a horizontal shaft rotating cylinder 14 is provided near the hulling section 1, a feeding control valve 4 is attached to the hulling section 1, and the horizontal shaft A layer thickness detection sensor 30 is provided inside the rotary cylinder 14, and the detection sensor 30 and the retraction iA1! When the detection sensor 30 moves up and down, the charge control valve 4 is connected to the i-valve 4 so that the charge control valve 4 opens and closes.
The mounting position can be freely adjusted regardless of the removal rate, and a demolition rate sensor 47 is provided at an arbitrary position, and the sensor 47 and the motor 34 are connected so that the detection sensor 30 is moved upward when the demolition rate is low. The gist of this invention is to configure an automatic adjustment device for a pot-hole type different grain sorting device in a hulling device that moves the detection sensor 30 downward when the grain ratio is high.
When brown rice with a high dehulling rate and a capacity higher than the brown rice sorting capacity of rotation Ql 4 is supplied into the rotary cylinder 14, the rotating screw shaft 35 is rotated in the forward direction to draw the top 36, and the arm 37 and the detection sensor 30 are connected to each other. The angle formed by the angle θ can be expanded from the initial setting angle θ to the angle α, and the interlocking ratio of the detection sensor 30 and the feed-in control valve 4 can be automatically changed to reduce the grain supply amount.

Moreover, when the removal rate becomes low, 1
````gnsa*''1''''''-''1゛1 of unhulled rice may accumulate, causing a so-called puncture phenomenon.
In the present invention, by measuring the load current value of the motor 5 driving the hulling roll 5 with the comparator 48,
When a change in the dehulling rate is detected and the dehulling rate becomes low, the control circuit 49 rotates the motor 34 in the forward direction, and similarly to the above, the interlocking ratio of the detection sensor 30 and the feeding control valve 4 decreases the grain supply amount. 1 Dynamically change it like this.
