Description

[Detailed Description of the Invention] Conventional rice hulling equipment was always equipped with a wind selection chamber.
The wind-selecting chamber was used to separate the rice husks from the paddy brown rice, but had no other function. Therefore, immature grains and broken rice are mixed into the paddy/brown rice, and all of these are fed to a swing-type sorting device.

Therefore, the sorting device is designed to not only separate unhulled rice and brown rice, but also to separate immature grains.

However, as is well known, in the sorting process using the oscillating sorting device,
It is extremely difficult to separate even immature grains, and there is currently no definitive equipment available.

Therefore, the present invention is specifically designed to remove immature grains in a wind selection chamber.

Originally, the idea was that immature grains could not be separated by wind sorting, and therefore they were separated using a swinging sorter, but the idea of completely separating all of them in the wind sorting room was changed. If you take the idea of discarding the grains and taking as many immature grains as possible, it is possible to separate the immature grains by wind selection.

Therefore, the amount of immature grains supplied to the oscillating sorter becomes very small, which not only makes it extremely easy to separate them, but also creates so-called rice sorters (vertical lines) in the flow channels formed everywhere. ), it becomes possible to almost completely remove immature grains.

Rotary sorting devices are now widely used to remove immature grains. This too cannot be removed by wind sorting, so it was formed separately, but if that is the case, the idea of incorporating it inside the hulling device, which is a rotary sorting device, naturally arises (that proposal has already been made public). ing),
This method increases the cost by an amount, and the present invention includes: a.

b. Rubber rolls are installed in the hulling room.

There is a wind selection room at the bottom of the C-hulling room.

d. The wind sorting room will have an opening for dropping paddy brown rice, an opening for unripe grains, and an opening for dropping rice husks.

The gist of the invention is a rice hulling device that satisfies the following requirements.

To explain with a diagram, (1) is the supply hopper, (2) is the feeding roll, and the feeding roll (2) is the hopper (
Among the inclined plates +31 to +41 forming 1), the tip (5) of the inner inclined plate (3) is fixed to the inside of the tip (5) so that it is extended toward the outer inclined plate (4). and,
The lower end (6) of the outer inclined plate (4) is formed a little longer so that the lower end (6) faces the hulling part (9) of the rubber rolls +71 +81. Rubber roll +71 +81
Of these, the comb roll (7) is pivoted diagonally upward, and the rubber roll (8) is pivoted diagonally downward. The line A connecting the axis Ql of the rubber roll (7) and the axis +Ill of the rubber roll (8) and the extension line of the lower end (6) form a T-shape.

A pair of rubber rolls +71 [Among 81, the upper rubber row/L, +71) axis Ql is a rotation axis, and the rubber roll (7) is only free to rotate, but the axis aυ of the lower rubber roll (8) is movable. It is also free to move in the direction of arrow W. Also, the rubber roll ()) is rotated faster than the rubber roll (8). However, unhulled rice a2 flowing through the outer inclined plate (4) and flowing out from its lower end (6)
is formed so as to transfer from its lower end (6) to the upper surface a3 of the lower rubber roll (8).

The rubber roll +71 [81] is provided in the hulling chamber 04. The hulling room α4 is formed by two vertical iron plates. Iron plate a9αe is rubber roll +71
They are mounted opposite each other at a distance that can accommodate +81 k. A vertical iron plate αS is installed at the same interval as the hulling room a4 so as to form a bearing room αη next to the hulling room I.
is provided. The bearing (1) of the shaft a9 of the feed roll (2) is attached to the upper position of the iron plate αe as. The shaft 09 is the shaft of the feeding roll (2) and the moving rubber roll (8).
Also serves as the supporting shaft of A bearing (A) is mounted on the outer periphery of the shaft a9 within the bearing chamber aTl. An arm QIl is attached to the lower end of the bearing, and a bearing @ is mounted on the lower end of the arm.
Insert the shaft (li+) of the moving roll (8) into the bearing.A protrusion is attached to the lower end of the bearing, and the adjustment rod is inserted through it.The protrusion is horizontal; And axis α
This is a direction perpendicular to B. The rod c14 has a threaded portion at one end thereof, and is screwed into a threaded cylinder (5) attached to a side wall (c) inside the threaded portion. (to) is the adjustment knob. The cap 241 is loosely fitted into the protrusion (C), and its tip protrudes from the protrusion to form an enlarged portion in the protrusion.
Wind the coil spring ■ between c) and the screw tube. C1l
+ is a supply hopper, and cA3 is an opening/closing shutter. A winnowing room (to) is formed between the iron plate α9 and aSO which form the hulling room α4. The air selection room (to) is different from conventional ones and is configured so that it can also perform air selection of immature grains. Husking room a
The bottom of < is formed into an inverted C-shaped funnel (B), and the lower end opening S (to) opens into the wind selection chamber (to). A windmill is installed directly below the hulling room I. 6η is the axis,
The bearing (end) of the shaft 6η is formed so as to be attached to the iron plate α, and is curved downward at its upper end. In order to form the upper end i1Q, a substantially concentric curved wall 0υ is attached inside, and a suction port 0 is opened inside the curved wall 0υ. The suction port tea is formed on the iron plate aG. or,
The suction port of the windmill is opened in the iron plate ae. The suction port (43) and the suction port (43) are connected by the connecting passage (2). Therefore, the wind from the windmill (G) circulates.
is formed within the bearing chamber aD. On the lower side between the air outlet (toward) and the upper end, a paddy brown rice fall opening (4!9) is formed near the air outlet (to), and then an immature grain fall opening m & shadow is formed. Upper end f4G A rice husk fall opening αη is formed at the bottom of the rice husk.

A motor (c) is provided in the bearing chamber an (husking chamber α4@, if necessary). Therefore, motor - drive pulley (19, axis of feed roll (2) + pulley ω of 19)
- Pulley 6υ on the axis oIl of the moving rubber roll (8), pulley 63 on the axis a0 of the fixed rubber roll. ffl car (to)
The pulleys (3) of the shaft an are both mounted on the same plane outside the iron plate 0 seconds, and a single belt 541 is hooked on and rotated. The belt (goods) may be made into multiple pieces if necessary. (G) is a safety cover. Note that the pulley 59 is formed in the pulley 63.

Next, I will explain the effect.

Since the present invention has the above-described configuration, when the unhulled rice is supplied to the supply hopper O1l and the opening/closing shutter O3 is opened, the unhulled rice (I2
is fed out by the feeding roll (2), flows on the inclined plate (4), and flows from its lower end (6) to the upper surface a of the moving roll (8).
3 and is supplied to the hulling section (9) without being disturbed by the slowly rotating moving roll (8).

In the hulling section (9), the rice is strongly rubbed by a fast-rotating fixed roll (7) to remove the hulled rice, leaving unhulled rice, unhulled brown rice, and rice husk 9.
The mixture is collected in a funnel (b) and its bottom opening (c)
It flows into the wind selection room (To). Inside the wind selection room (To),
Because the wind from the windmill is blowing up, the heavy grains fall into the paddy/brown rice fall port 0!9, the immature grains advance a little and fall into the immature grain fall port ■, and the rice husks fall into the rice husk fall port. t<7). The sorting air is sucked into the suction port i43, passes through the passage circle, and circulates to the suction port i43.

Among the above, the present invention is characterized in that an immature grain falling port i4e is particularly formed in the wind sorting chamber (end), and therefore, the subsequent separation of unhulled rice and brown rice can be performed with great accuracy. In addition, it has the characteristic of completely separating immature grains.
