Description

[Detailed description of the invention] The present invention relates to a rice hulling device.

Conventionally known hulling devices are equipped with a lift or a thrower for finished rice, from which finished rice is discharged one after another, but it has not been possible to pack this into bags. This is because a large number of immature grains were mixed into the finished rice, so the conventional method was to direct the discharged finished rice to an expensive sorting machine called a rice grader. With this, I was sorting out immature grains while putting them into a weighing bag. Of course,
Among the inventions and ideas, there were some that installed immature grain removal plates in the flow path of the hulling device, but these were just hopeful devices and did not have sufficient effects, so they were also used for rice hulling. I needed a grader.

However, in the same way, there is an immature grain sorting plate (net) in the flow path.
Even if the flow path is formed as shown below, the length of the flow path can be made sufficiently long, so that the proportion of immature rice mixed in the finished rice is very small. It is possible to weigh and pack into bags without using specialized sorting equipment.

Therefore, the present invention integrates a hulling section, a rice sorting section, an immature grain separation section, and a weighing section to provide a compact, compact, inexpensive, and high-performance hulling device. A rice hulling part is provided at a side position of the rice hulling elevator, a wind sorting part is provided at the side or lower part of the rice hulling part, and a swing type sorting part which swings in the front and back direction is provided at the lower part of the rice hulling part. A brown rice take-out port and a unhulled rice take-out port are formed on the left and right sides of the swing-type sorting section, and the unhulled rice loading elevator and the hulling section are connected by a flow path, and the hulling section and the wind sorting section are connected to each other by air flow from the hulling section. The wind sorting section and the swinging sorting section are connected so that the wind-sorted grains flow into the swinging sorting section and are sorted. A brown rice flow gutter is provided at the brown rice outlet, an immature grain sorting plate (net) is attached to the bottom plate of the brown rice flow gutter, the end of the brown rice flow gutter is connected to a finished rice elevator, and the upper part of the finished rice elevator is connected to the bottom of the brown rice flow gutter. A rice hulling device is provided with a storage tank with an on-off valve, and a measuring bagging device is provided below the storage tank, and
The gist of the invention is that the on-off valve and the weighing and bagging device are interlocked by a switch and a solenoid to perform the weighing and bagging operation.

To explain it with a diagram, 1 is an elevator for loading unhulled rice, and guide rolls 2.3 are attached to the upper and lower sides, and a packet belt 4 is hooked and rotated on the guide rolls 2.3. A loading port 5 is formed at the lower end of the unhulled rice loading elevator l, and a loading hopper 6 is attached to the loading port 5. A discharge lower is opened at the side of the upper end of the A unloading board 1 for loading unhulled rice, and a fixed hopper 8 is directly attached to the outside of the discharge lower. Since the fixed hopper 8 is fixed, it does not move up and down, and is therefore directly fixed to the outside of the discharge lower with a set screw or the like, and the lower end of the fixed hopper 8 is provided at a lower position. It is fixed to the upper surface of the outer case 1o of the rice hulling section 9.

As a result, the fixed hopper 8 has both the function of temporarily storing grains and the function of firmly fixing the upper end of the unhulled rice loading elevator l.

A hole 11 extending over 7 degrees is formed in the midsection of the fixed hopper 8, and a chain hole 11. The upper end of the tube is fitted into the
The lower end of the tube is opened into the filling hopper 6. Reference numeral 12 denotes an on-off valve, which is closed manually or automatically. Inside the hulling section 9, a pair of hulling rolls 13.14 are mounted by shafts 15.16. The hulling rolls 13, 14 in the embodiment are mounted in a diagonal top-bottom relationship. Immediately below the on-off valve 12, a feed roll 17 is provided. Feeding roll 1
A sink plate 18 is provided below 7, and the lower end of the sink plate 18 faces between the hulling rolls 13 and 14.

A blower 19 is provided below the sink plate 18.

The blower 19 is formed by a cross-flow fan. The blower 19 is long in the width direction and spans approximately the entire width. Blower 19
The air passage 20 passes under the hulling roll 14 and passes through the wind selection section 2.
Air is blown within 1. A swinging type spreading device 22 is provided on the discharge side of the hulling roll 13.14.
The ejected grains are spread out several times more in the width direction.

That is, 23 is a suction blower attached to the side of the wind selection section 2.1, an eccentric wheel 25 is attached to its rotating shaft 24, the upper end of a rod 26 is fixed to the eccentric wheel 25, and the rod 26
The lower end of is fixed to the rocking diffuser 22.

The swing type diffuser 22 is elastically supported by a leaf spring 27. Instead of the leaf spring 27, a swing support rod may be used. The lower end opening 28 is formed to become wider toward the tip.

Reference numeral 29 denotes a distribution supply gutter which is fixed to the supply portion of the sorting plate 31 and swings together with the sorting plate 31. A large number of feed protrusions 30 are formed on the bottom surface of the distribution supply gutter 29 . The sorting plate 31 has a structure in which multiple stages are stacked, and the distribution supply gutter 29 distributes and supplies the sorting plate 31 to each stage. The sorting plate 31, like the guide roll 2.3, the shaft 15.16, the rotating shaft 24, etc., can be swung back and forth on a swinging support 33.34 attached to a shaft 32 provided in the left and right directions. It can be installed freely.

The sorting plate 31 has a rectangular shape, and as shown in FIG. A brown rice rocking protrusion 37 is formed which is inclined in the direction of the brown rice outlet 35, and an unhulled rice rocking protrusion 38 which is inclined in the direction of the unhulled rice outlet 36 is formed on the rear ⅓. The lower end of the swinging support rod 33 is pivoted 40 to the underframe 39, and the lower end of the swinging support rod 34 is attached to the underframe 39.
It is pivoted to a horizontal rod 41 that is provided at 9 so as to be vertically movable. A rotation shaft 42 is provided above the horizontal rod 41, and the rotation shaft 4

The lower end of a rod 52 is connected to a cam 53 attached to a shaft 54 at the upper end of the swinging support 33, and the rod 52 and the swinging support 33 are formed at an angle θ smaller than a right angle to provide a quick return.

Outside the brown rice outlet 35, a brown rice flow gutter 55 is provided across the entire width in the front-rear direction, and an immature grain sorting hole 56 is formed in the brown rice flow gutter 55. 57 is a pole for preventing clogging. The brown rice flow gutter 55 is formed so that the rear side is slightly lower than the front side and has a gentle slope, and the brown rice is formed to move in a lower direction because the brown rice flow gutter 55 swings. 58 is a finishing rice elevator,
At the lower end, there is a hopper 5 facing the end of the brown rice flow gutter 55.
9, and a storage tank 60 is attached to the upper end. An automatic on-off valve 61 is attached to the opening at the lower end of the storage tank 60, and a platform scale 62 is provided below it, and the platform scale 62 and the automatic on-off valve 61 are connected by a switch and a solenoid.

Next, we will discuss the effect.

Briefly, unhulled rice a supplied to the unhulled rice tensioning elevator l rises and is supplied to the hulling section 9, where it becomes unhulled rice a, brown rice and rice husk C, which are separated from the sides. The rice husks C are fed into the wind sorting section 21, where the rice husks C are wind sorted, and only the unhulled rice a and the brown rice sludge flow into the swing-type paddy sorting section and are sorted, and the unhulled rice a is returned to the unhulled rice loading elevator mi. The brown rice is taken out as finished rice.

To describe the specific action, the raw material, unhulled rice a, is inserted into the loading port 5.
When supplied, it is raised by the packet belt 4 in the unhulled rice loading elevator 1, and stored in the fixed hopper 8 from the discharge lower. When the stored amount exceeds, it flows out from the overflow hole 11 and is returned to the filling port 5. By opening the on-off valve 12, the grain stored in the fixed hopper 8 is fed out by the feeding roll 17, and flows on the inclined sink plate 18 to the huller which is diagonally above and below the lower end of the sink plate 18. The grain is fed between the rolls 13 and 14, is hulled, and then flows into the swinging spreader 22. However, the suction blower 23
The rotating shaft 24 of is rotated, and the eccentric ring 25 is fitted onto the rotating shaft 24, so when the rotating shaft 24 rotates, the eccentric ring 25 rotates, and the upper end is fixed to the eccentric ring 25. The rod 26 vibrates diagonally up and down, and therefore the rocking diffuser 22 fixed to the lower end of the rod 26 vibrates diagonally up and down. During this time, the leaf spring 27 elastically supports the swinging diffuser 22.

Therefore, when the hulled grains in the swinging type spreading device 22 flow out from the lower end opening 28, they fall in a state where they are uniformly spread in the width direction and are supplied into the distribution supply gutter 29.

Thus, the air sucked by the blower 19 passes through the air passage 20, passes below the rocking diffuser 22, passes through the grains of rice grains falling from the lower end opening 28, and rises into the wind selection section 21. At this time, the light rice husks C are blown away and sorted, and the rice husks C are sucked into the suction blower 23 and removed from the system.

The hulled grains that are spread out in the width direction from the lower end opening 28 and fall uniformly are supplied onto the distribution feed gutter 29 . The distribution supply gutter 29 is integrally attached to the sorting plate 31, and since the sorting plate 31 is attached so as to be swingable in the front and rear directions by swinging support rods 33 and 34, the distribution and supply gutter 29 is also attached to the sorting plate 31. Therefore, it is fed by the feed protrusion 30 on the bottom wall, partitioned by a partition plate provided at the end, and distributed and supplied to the sorting plates 31 of each stage. When the sorting plate 31 moves to the front, the unhulled rice a and brown rice su supplied onto the sorting plate 31 are sorted by moving the brown rice that has settled to the lower layer toward the brown rice outlet 35 due to the action of the brown rice rocking protrusion 37. Board 3
When - and l move to the rear side, the unhulled rice floating in the upper layer is moved in the direction of the unhulled rice outlet 36 by the action of the unhulled rice rocking protrusion 38, and the brown rice is taken out from the brown rice outlet 35 to the brown rice flow channel 55. The unhulled rice is taken out from the unhulled rice outlet 36.

Although the brown rice taken out to the brown rice flow gutter 55 contains a considerable amount of immature grains, immature grain sorting holes 56 are formed along the entire length of the bottom of the brown rice flow gutter 55. The length of the brown rice flow gutter 55 is quite long, and especially immature grains fall from the front side of the brown rice outlet 35.
Since the brown rice is sorted for a long time, when it flows into the hopper 59 from the brown rice flow channel 55, there are no immature grains. Therefore, the brown rice stored in the storage tank 60 by raising the finished rice elevator 58 does not contain immature grains, and a grain bag 63 is placed on the scale 62, and the automatic opening/closing valve 61 is opened to weigh and fill the rice into bags one after another. It can be done.

The present invention is as described above, and in particular, a hulling part is provided at a side position of an elevator for loading unhulled rice, a wind selection part is provided at a side or lower part of the hulling part, and a wind selection part is provided at a lower position of the hulling part.
