Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rice hulling device.

(Prior art) Conventionally known Utility Model Publication No. 59-9693 and Utility Model Publication No. 1987-9693
Publication No. 55-58236 and Publication No. 59-6892 disclose a swinging sorting section surrounded by a frame, a supply elevator and a take-out elevator attached to the side of the swinging sorting section, It consists of a hulling section placed on the upper part of the frame body on the side closer to the elevator, and a wind selection part placed on the upper part of the frame body on the side farther from the elevator. The document describes a hulling device in which a hulling roll is arranged at the same height within the hulling section and is in communication with the wind sorting section.

(Problems to be Solved by the Invention) In the known example, the hulling section is placed on the side closer to the elevator, and the wind selection section is placed on the side farther from the elevator, and the hulling section and the wind selection section are arranged inside the elevator. However, since the hulling rolls in the hulling section are at the same height on the left and right, and the hulling material is slid down directly below, it is not easy to guide it to the winnowing section on the side farther from the elevator.

(Object of the Invention) The present invention provides a method for guiding the rice from the hulling part to the wind sorting part in a product having a hulling part placed on the side closer to the elevator and a wind selection part placed on the side farther from the elevator. In addition, a separate air blower and suction blower are installed to make the air selection effect more noticeable.

(Means for Solving the Problems) Therefore, the present invention provides a swing type sorting section 31, a supply elevator 1 attached to a side of the swing type sorting section 31, and a swing type sorting section 31. It consists of a hulling section 8 placed on the side near the elevator on the upper part of the paddy, and a wind sorting section 21 placed on the side farther from the elevator 1 on the upper part of the swing type sorting section 31. The sliding part 8 and the wind sorting part 21 communicate with each other internally, and in the hulling part 8, one hulling roll 13 is arranged in an upper position and the other hulling roll 15 is arranged in a lower position. The surimono is discharged toward the wind selection section 21,
A swinging type diffusion device 20 is provided between the hulling section 8 and the wind selection section 21 to diffuse the hulled material produced by the hulling rolls 13 and 15 and release it to the wind selection section 21. A sorting air passage 27 is formed in the lower part of the type diffusion device 20, which passes through the lower part of the hulling rolls 13 and 15 and applies a sorting air to the waste discharged from the swinging type diffusion device 20. A blower 19 is provided at the starting end of the screening air passage 27.
At the terminal end of the wind selection section 21, a spiral air passage 29 is provided via an ascending air passage 28, and a suction blower 22 is attached to the terminal end of the spiral air passage 29 to form a hulling device.

(Example) To explain with the drawing, 1 is a supply elevator, guide rolls 2 and 3 are attached to the upper and lower sides, and a bucket belt 4 is wound around the rolls. A charging port 5 is formed at the lower end of the supply elevator 1, and a charging hopper is attached to the charging port 5.

A supply port 6 is opened at the side of the upper end of the supply elevator 1, and a fixed hopper 7 is directly attached to the outside of the supply port 6.

The fixed hopper 7 is usually made of plastic, but the feed elevator 1 and the fixed hopper 7 may be integrally made of plastic.

The fixed hopper 7 is of a fixed type and does not move up and down, so it is directly fixed to the outside of the supply port 6 with a set screw or the like, and the lower end of the fixed hopper 7 is at its lower position. It is fixed to the upper surface of the outer case 9 of the rice hulling section 8 provided.

As a result, the plastic fixed hopper 7 has the effect of temporarily storing grains and the effect of firmly fixing the upper end of the feeding elevator 1. In particular, the latter effect is quite large. (The top of the elevator vibrated every time the oscillating sorting device swung.)

An overflow hole 10 is formed in the midsection of the fixed hopper 7. 11 is an on-off valve.

Inside the hulling section 8, there are diagonally vertically arranged:
A pair of hulling rolls 13 and 15 are fixed by shafts 12 and 14. The axial direction of the shafts 12 and 14 is the same as the axial direction of the guide rolls 2 and 3. Said on-off valve 1
Immediately below 1, a feed roll 16 is provided. A sink plate 17 is provided at the bottom of the feeding roll 16, and the lower end 18 of the sink plate 17 is connected to the hulling roll 1.
It is happening between 3 and 15.

A blower 19 is provided outside the hulling rolls 13 and 15 with the sink plate 17 interposed therebetween. The blower 19 is long in the width direction and spans approximately the entire width. The sorting air passage 27 of the blower 19 is connected to the hulling roll 1.
The air is blown into the air selection section 21 through the lower side of the air filters 3 and 15.

A swing type spreading device 20 is provided on the discharge side of the hulling rolls 13, 15, and spreads the grain discharged from the hulling rolls 13, 15 in the width direction. That is,
Reference numeral 22 denotes a suction blower attached to the side of the wind selection section 21. An eccentric wheel 24 is attached to the rotating shaft 23 of the suction blower 22, and a rod 25 is fixed to the eccentric wheel 24.
A swing type diffuser 20 is fixed to the other end of 5.

The swing type spreading device 20 has a lower end elastically supported by a plate spring, and the lower end opening violently vibrates diagonally up and down when the eccentric wheel 24 rotates, and the hulled grains that have been hulled by the hulling section 8 are moved in the width direction. spread to.

32 is a distribution/supply gutter provided at the lower part of the lower end opening of the rocking diffuser 20. Distribution supply gutter 32
A large number of feeding protrusions 33 are provided on the bottom surface. The distribution supply gutter 32 is fixed to the upper surface of the sorting plate 34.

The sorting plate 34 has a structure in which a plurality of stages are stacked, and is attached so as to be swingable from side to side by a swinging support rod 35 attached to a shaft provided in the front-rear direction.

36 is a sorting protrusion formed on the upper surface of the sorting plate 34, 37 is a large foreign matter removal plate, 38 is a port for returning unhulled rice, 39 is an exhaust pipe, and 40 is a drain for taking out unhulled rice.

Note that 26 is a suction port.

(effect) Next, we will discuss the effect.

To describe the overall general operation, the unhulled rice supplied to the feed elevator 1 rises and is supplied to the hulling section 8, where it becomes unhulled rice, brown rice, and unhulled grains. The paddy grains are wind-selected here, and only the unhulled rice and brown rice flow into the swing-type sorting section 31 and are sorted.The unhulled rice is returned to the supply elevator 1, and the brown rice is removed from the system. are excluded.

Specifically, when unhulled rice is supplied to the feeding port 5, it is raised inside the feeding elevator 1 by the bucket belt 4 and stored in the fixed hopper 7 through the feeding port 6. When the storage amount exceeds, it flows out from the overflow hole 10 and fills the filling port 5.
will be returned to.

By opening the on-off valve 11, the unhulled rice stored in the fixed hopper 7 is fed out by the feeding roll 16, and flows on the inclined sink plate 17 to reach the huller, which is diagonally above and below the lower end of the unhulled rice. roll 13,1
5, the rice is hulled and sent to the swinging type spreading device 2.
Flows into 0. The rotating shaft 23 of the suction blower 22 is rotated, and the eccentric ring 24 is fitted onto the rotating shaft 23. Therefore, when the rotating shaft 23 rotates, the eccentric ring 24 rotates, and the eccentric ring 24 rotates. The rod 25, whose upper end is fixed, vibrates diagonally up and down, and therefore, the rocking diffuser 20, which is fixed to the lower end of the rod 25, vibrates diagonally up and down. Meanwhile, the leaf spring elastically supports the rocking diffuser 20.

Therefore, when the hulled material in the swinging type spreading device 20 flows out from the lower end opening, it falls in a state where it is uniformly spread in the width direction and is supplied into the distribution feed gutter 32. Thus, the air blown by the blower 19 passes through the sorting air passage 27, passes below the swinging type diffusion device 20, passes through the grains of rice grains falling from the swinging type diffusion device 20, and passes through the wind selection section 21. When ascending through the ascending air passage 28, the grains are left behind and the lighter paddy grains are blown away and sorted.
9 to the suction blower 22 and removed from the system.

The hulled material that has fallen from the swinging type spreading device 20 is supplied onto the distribution supply gutter 32 . The distribution supply gutter 32 is integrally attached to the sorting plate 34, and the sorting plate 34 is attached so as to be swingable in the left and right direction by a swinging support 35, so the distribution supply gutter 32 is also attached to the sorting plate 34. Therefore, it is fed by the feed protrusion 33 on the bottom wall and distributed and supplied to the sorting plates 34 of each stage.

Paddy rice and brown rice supplied onto the sorting plate 34 are sorted by the action of the sorting protrusion 36, the brown rice is taken out from the brown rice outlet into the brown rice channel, the unhulled rice is taken out to the unhulled rice outlet 40, and straw waste etc. are removed. Then, only the unhulled rice flows into the unhulled rice return port 38, joins with the unhulled rice from the loading port 5, and is reprocessed.

(Effect) Previously known Utility Model Publication No. 59-9693 and Utility Model Publication No. 59-9693
Publication No. 55-58236 and Publication No. 59-6892 disclose a swinging sorting section surrounded by a frame, a supply elevator and a take-out elevator attached to the side of the swinging sorting section, It consists of a hulling section placed on the upper part of the frame body on the side closer to the elevator, and a wind selection part placed on the upper part of the frame body on the side farther from the elevator. The document describes a hulling device in which a hulling roll is arranged at the same height within the hulling section and is in communication with the wind sorting section.

In the known example, the hulling part is placed on the side closer to the elevator, and the wind selection part is placed on the side farther from the elevator, and the hulling part and the wind selection part communicate internally. The hulling rolls inside the unit are at the same height on the left and right, and the hulled material is scraped straight down, so it is not easy to guide it to the winnowing unit on the side farther from the elevator.

However, the present invention has a swing type sorting section 31, a supply elevator 1 attached to the side of the swing type sorting section 31, and a supply elevator 1 mounted on the upper part of the swing type sorting section 31 on the side closer to the elevator. It consists of a hulling section 8 placed on the hull, and a wind sorting section 21 mounted on the upper part of the swing type sorting section 31 on the side farther from the elevator 1. are in communication with each other, and in the hulling section 8, one hulling roll 13 is arranged at an upper position and the other hulling roll 15 is arranged at a lower position, and the hulled products are directed toward the wind selection section 21. Between the hulling section 8 and the wind sorting section 21, there is a swing-type spreading device 20 that diffuses the hulled material produced by the hulling rolls 13, 15 and releases it to the wind sorting section 21.
A sorting air passage 27 is formed in the lower part of the rocking type diffusion device 20 for applying a sorting air to the discharged material released from the rocking type diffusion device 20 through the lower part of the hulling rolls 13 and 15. The sorting air passage 27
A blower 19 is provided at the starting end of the air selection section 21 at the terminal end of the screening air path 27.
8, a spiral air passage 29 is provided, and a suction blower 22 is attached to the end of the spiral air passage 29. Since the other hulling roll 15 is disposed at a lower position, the hulled material is discharged toward the wind selection section 21, and is easily guided to the wind selection section 21 located next to it.

(b) Furthermore, since a swinging type diffusion device 20 is provided between the hulling section 8 and the wind selection section 21 to diffuse the hulled material produced by the hulling rolls 13 and 15 and release it to the wind selection section 21. Combined with the effect of (a), the wind selection effect is improved.

C. The hulling roll 1 is installed at the bottom of the swinging type spreading device 20.
A sorting air passage 27 is formed that passes through the lower part of the air filters 3 and 15 to provide sorting air to the discharged material emitted from the swinging type diffuser 20, and a blower 19 is provided at the starting end of the screening air passage 27. Sorting is effective because it is sorted by a sorting wind while being diffused.

D. A spiral air passage 29 is provided in the air selection section 21 at the terminal end of the selection air passage 27 via the ascending air passage 28;
Since the rice hulling device is equipped with a suction blower 22 at the end of the swirl air passage 29, the wind from the sorting air passage 27 flows through the ascending air passage 28 and the swirl air passage 29 in the wind selection section 21.
Since it flows into the air, there is no wind turbulence and the sorting is good.
