Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain sorting device that uses a low cree separator for sorting unhulled brown rice and unhulled rice in a hulling device.・It is designed to automatically control the process.

Conventionally, the rice hulling device disclosed in Japanese Utility Model Application Publication No. 57-55536, for example, uses a rotary separator in the grain sorting section of the hulling device, but the rotary separator is a rotating type with a pot hole provided on the inner surface. A collection spiral trough is provided inside the drum to enable grain selection.

The above-mentioned known example has rotary separators in two upper and lower stages, and the upper rotary separator separates unhulled rice and 4-kongo rice, and the upper rotary separator separates brown rice and 1-kongo rice. However, apart from that, there are problems as described below.

FIG. 1 shows a schematic diagram of a hulling device using a rotary separator a in the grain sorting section, and b is a hulling roll. The hulled rice that has been hulled by the hulling roll b becomes a three-part hulled product consisting of hulled unpolished rice C, hulled rice d, and rice husk e, which is fed into the rotating drum f of the rotary separator a and transferred to the rotating tram f. The pot holes g formed on the inner surface are used to scoop up the unpolished rice C. At this time, the pot holes g are distributed in the layer inside the rotating drum f, and one paddy is scooped out. The second step is to leave the paddy rice d in the structure.
As is clear from the figure, the boundary between the hulled brown rice C and the unhulled rice d is not clear, so in order to leave only the pure unhulled rice d in the rotating drum f, the −is+ of the unhulled rice d must be
You will end up scooping up the s. In order to accurately expect such an effect, the proportion of brown rice C and unhulled rice d must be constant. Therefore, the effect changes greatly depending on the change in the hulling rate. That is, if the hulling rate does not reach a certain level, the unhulled rice d will not float as shown in Fig. 2, and the work of scooping with the pot hole g will change greatly.

The present invention improves this point and automatically keeps the hulling rate constant at all times, and includes a hulling chamber with a pair of left and right hulling rolls, and a roughly U-shaped collection volume inside. The hulling equipment consists of a grain sorting section equipped with a rotary separator that scoops out the separated grains through a hole formed on the inner surface of the jar and separates the 4-ton combined rice into unhulled unhulled rice and hulled unhulled brown rice. A hulling device using a rotary separator in which a rice meteor detection sensor is installed in the hulling path of the rotary separator, and the sensor is connected to an automatic roll gap adjustment device of the hulling roll, and the collection spiral receiving trough. An adjustment plate is installed to adjust the amount of rice to be collected (=J), and a switch that is turned on and off by the lever is installed near the adjustment lever that adjusts the angle of the adjustment plate, and an automatic gap adjustment of the hulling roll is performed. + A forward/reverse motor is attached to the device ((J) The switch and the motor are connected via a timer, a flow rate detection sensor, a storage device, and a control circuit to form the device described above.

To explain with reference to the drawings below, l is a stake hopper, a hulling chamber 2 is provided in the do portion of the stake hopper 1, and a pair of hulling rolls 3.3 are installed inside the hulling chamber 2. to be dressed. The hulling rolls 3.3 are formed so that the roll gap 34 can be automatically adjusted by forward and reverse rotation of a forward and reverse rotation motor 33, as shown in FIG. A wind selection room 4 is formed in the lower part of the hulling room 2, and a suction fan 6 and a discharge pipe 7 are installed in this wind selection room 4. A discharge port 8 is opened at the tip of the discharge pipe 7. Also,
A flowing gutter 5 is provided in the wind selection chamber 4, and a receiving gutter 9 for one-kungo rice consisting of hulled unpolished rice and unhulled rice, and an immature grain receiving gutter 10 are formed on the lower blade of the flowing gutter 5, respectively. The mixed rice receiving channel 9
, Immature grain receiving trough log = spiral conveyor 11
．． 12 are installed horizontally. Thus, a grain sorting section 13 is provided adjacent to the hulling room 2. Inside the grain sorting section 13, rotary separators 14 and 15 are rotatably installed horizontally in two lower stages. 16 is a single-stage rotary separator 14
The rotating drum 16 has a number of pot holes 17 on its inner surface as shown in FIGS. 1 and 2. Rotating drum 16
A mixed rice collection spiral receiving trough 18 having a substantially U-shaped cross section is provided at the center. 19 is a spiral conveyor installed horizontally on the mixed rice collection spiral receiving trough 18. 20 is an adjustment plate attached to the mixed rice collection spiral receiving trough 18, which is raised and lowered,
Adjust the separation of brown rice and mixed rice. 21 is the adjustment plate 20
There is a switch 2 near the adjustment lever 21.
2 will be provided. A supply funnel 23 is provided on the opposite side of the grain sorting section 13 from the hulling room 2. Two wheels of the thrower 24 attached to the discharge end of the mixed rice receiving trough 9 open onto the feed funnel 23. An extinguisher [J26] is opened at the end of the mixed rice recovery spiral receiving trough 17, which is inserted into the rotating drum 25 of the lower rotary separator 15. 27 is a mixed rice spiral receiver. A stake hopper l is installed on the hulling room 2 side of the grain sorting section 13.
A downstream MJ28 is formed. The unhulled rice discharged from the discharge side 29 of the rotary drum 16 is returned to the loading hopper 1 through the downflow gutter 28. A flow rate detection sensor 30 is mounted on the bottom plate of the downflow gutter 28. The flow rate detection sensor 30, switch 22, and forward/reverse rotation motor 33 are connected as shown in FIG. That is, the timer 31 is connected to the switch 22.
Combine the timer 31 with the 7% detection sensor 30
and is further coupled to a forward/reverse rotation motor 33 via a storage device 32 and a control circuit 35.

Next, we will discuss the effect.

First, when the raw material paddy is supplied to the loading hopper l, the raw material paddy flows and flows into the hulling chamber 2, and the hulling rolls 3, 3. The unhusked rice is washed down the downflow gutter 5L and flows into the winnowing chamber 4. In the wind selection chamber 4, suction air is blown by the action of the suction fan 6, so that the light rice husks are discharged from the discharge port 8 through the discharge pipe 7. The immature grains advance a little by the suction wind, flow into the immature grain receiving trough lO, and are taken out by the conveyor 12. The mixed rice of unhulled brown rice and structured paddy rice flows into the mixed rice receiving trough 9, is supplied to the thrower 24 by the conveyor 11 on the receiving trough 9, and is fed to the grain sorting section 13 by the action of the thrower 24. 23. Then, it is supplied to the rotating drum 16 of 42 parts from the supply leak 1.23, and is stirred by the rotation of the rotating drum 16. Then, based on a well-known theory, brown rice, which has a higher specific gravity, sinks to the bottom layer, and unpaddy rice, which has a higher specific gravity, floats to the upper layer! d.

Therefore, the brown rice that has sunk to the upper layer and a portion of the unhulled rice that has floated to the upper layer are scooped out by the pot hole 17 formed on the inner surface of the rotating drum 16 and taken out to the mixed rice collection spiral receiving trough 18.
The mixed rice is conveyed horizontally through the spiral receiving trough 18 and then from the drop opening 26 to the lower part - the rotating drum 2 of the tally separator 15.
Supplied within 5 days. As mentioned above, the upper rotating drum 1
In step 6, not only brown rice but also some of the unhulled rice is scooped up through the pot hole 17, so all that remains in the rotating drum 16 is unhulled rice, which is discharged from the discharge side 29 to the drain gutter 28. It is then returned to the loading hopper 1 and processed at 11f. The mixed rice supplied to the rotary drum 25 of the third stage is scooped out through the pot hole 17, and only the bottom layer of sunken brown rice is scooped out and taken out to the mixed rice recovery spiral receiving trough 27, where it is taken out as finished rice. However, as described above, the sorted returned unhulled rice flows into the downflow gutter 28, but the flow rate is determined by the flow rate detection sensor 30.
The storage device 32 and the control circuit 35
is transmitted to the forward/reverse rotation motor 33 through the hulling roll 3.
．． The gap in step 3 is automatically adjusted to ensure a constant hulling rate.

Generally, the hulling device uses a swinging type unhulled rice separating device as a means for separating the mixed rice of the unhulled unhulled rice and the unhulled rice. Although there were no problems with this device in terms of performance, it did have defects in that the entire device was a large piece of work and had large vibrations. Therefore, a rotary separator that was developed separately prevents the above-mentioned defects, but as mentioned above, when the hulling rate changes, the function changes and the performance becomes unstable.

However, in the present invention, the hulling chamber 2 has a pair of left and right hulling rolls 33, and an approximately U-shaped collection spiral receiving trough is provided inside, and the sorted grains are scooped out through a pot hole 17 formed on the inner surface, and the grains are scooped out to form paddy rice. Rotary separator 14 that sorts the mixed rice of rice and hulled brown rice
．． 15, a hulled rice flow rate detection sensor 30 is provided in the hulled rice path of the rotary separator 14.15, and the sensor 30 and the roll gap automatic adjustment device of the hulling roll 3 are A rice husking device using a rotary separator connected so that the roll gap can be automatically adjusted according to the amount of rice returned, and an adjustment plate 2o that can adjust the amount of recovered rice are installed in the recovery spiral receiving trough.

A switch 22 that is turned on and off by the lever is installed near the adjustment lever 21 that adjusts the angle of the adjustment plate 20, and a forward/reverse motor 33 is connected to the automatic gap adjustment device for the hulling roll 3.
, and the switch 22 and the motor 33 are connected via the timer 31, the flow rate detection sensor 30, the storage device 32, and the control circuit 35. However, it is effective as a stable hulling device.
