DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hulling sorter composed of a dewatering unit, a wind selection unit, and a pot-hole type rotary selection unit.

[0002]

2. Description of the Related Art Conventionally, it has been constituted by a removing part, a wind selecting part, and a pot hole type rotary sorting part in which a brown rice gutter is inserted in a sorting barrel having countless pot holes formed on an inner peripheral surface. Rice hulling sorting equipment is well known.

[0003]

However, in such a hulling apparatus, when the evacuation rate in the evacuation unit is low, the ratio of the hulled rice to the unpolished rice in the mixed rice fed into the sorting cylinder is high. As a result, the lifting efficiency due to the pot hole on the inner peripheral surface of the sorting cylinder is reduced, and the sorting efficiency and the sorting accuracy of the pot-hole type rotary sorting unit cannot be exhibited. If the water content is low, the mixing ratio of the paddy is reduced, but the mixing ratio of the paddy is further reduced even when the removal ratio of the removal unit is high, to improve the performance of the pot-hole type rotary sorting unit. The purpose is to improve the performance of the hulling sorting device.

[0004]

Accordingly, the present invention provides an apparatus for sorting mixed rice by specific gravity sorting in a post-process of a degassing section and a wind screening section, and the apparatus selected by the apparatus is used as a pot-hole type rotating machine. By adopting a configuration in which sorting is performed by the sorting unit, the mixed rice that has passed through the deaeration unit and the wind selection unit is sorted by specific gravity sorting, and the sorted rice will be carefully selected by the pot-hole rotary sorting unit. In addition, the ratio of brown rice in the mixed rice supplied into the sorting cylinder of the pot-hole type rotary sorting unit is increased, the lifting action by the pot hole is improved, and the sorting efficiency and the sorting accuracy are increased.

[0005] Then, an apparatus for sorting by specific gravity sorting is
If it is installed inside the sorting cylinder of the pot-hole type rotary sorting unit, the sorting efficiency and the sorting accuracy will be improved while the whole apparatus is compact.

[0006] Further, by using an oscillating sorter as a device for sorting by specific gravity sorting, the sorting state at the time of specific gravity sorting can be grasped, and sorting adjustment can be easily performed.

[0007] In this case, if the swing direction of the sorting board in the swing sorting machine is orthogonal to the direction of the rotation axis of the sorting cylinder, and the falling direction of the sorting board is the same direction as the direction of the rotation axis, the falling on the sorting board is performed. This increases the stroke and improves the sorting action of the swing sorting machine.

[0008] Further, the paddy sorted by the rocking sorter is returned to the sludge removing unit to be sledged again, and the material discharged from the terminal end of the inner circumferential surface of the sorting drum is returned to the swing sorter to be sorted again. By doing so, the reduction of the paddy and the mixed rice becomes effective, the rubbing is prevented twice, no damage is caused by the misalignment of the skin, and the sorting action by the pot hole is improved.

The removal roll shaft and the rotation axis of the sorting cylinder are perpendicular to each other. By being located next to it, the supply route of the mixed rice from the wind selection unit to the rocking sorter,
The return path of the brown rice sorted by the rocking sorter to the escaping section and the circulation path to the rocking sorter that is discharged from the terminal end of the inner circumferential surface of the sorting drum become rational.

[0010] Furthermore, the roll shaft and the rotation axis of the sorting cylinder are made to be in the same direction, and the high stream in the downstream direction of the sorting board is set to the right side of the hulling sorting apparatus, and the low stream is set to the left side. If a pothole type rotary sorting part is placed next to the part ぷ, the front and rear length of the device is compressed and united, and it is easy to check the sorting state on the left side of the device, that is, on the sorting board of the worker who is operating, and the sorting is performed. Adjustment is easy.

The end of the brown rice receiving trough (14) is communicated with the brown rice sorting air duct (9) by a brown rice extracting gutter (23), and the trailing end of the inner peripheral surface of the sorting cylinder (1) is for taking out mixed rice. Gutter (2
4) leads to the above-mentioned rubble sorting air path (8).
(25) shows a brown rice thrower that lifts and removes brown rice in the horizontal brown rice gutter (12).

As a result, the paddy in the paddy funnel (4) is rubbed off by a derolling roll (5), and the rubbed material falls into a rubbed material sorting air path (8) and is selected by wind. The chaff is sucked by the suction / dust fan (6) and discharged out of the machine, and the pity is taken out from the pity take-out gutter (10), and the mixed rice of brown rice and paddy gathers in the mixed rice horizontal gutter (11). The rice is then lifted by a mixed rice thrower (17) into a mixed rice supply gutter (16), and the supply gutter (1
From 6), the high level in the downflow direction (Y) of the sorting board (2) is supplied to the alligator, and the low level flows into the alligator while drifting on the oscillating sorting board (2), causing the sorting board (2) to swing down. The paddy flowing out of the paddy is separated from the mixed rice by the paddy sorting plate (22), falls into the paddy trough (18), and is transferred from the terminal end of the paddy trough (18) to the paddy funnel (4) by the paddy thrower (19). ) Will be returned to you again.

Then, the mixed rice separated from the paddy by the paddy sorting plate (22), that is, most of the paddy is removed as described above from the swinging up of the sorter (2), and the ratio of brown rice is increased. Mixed rice falls on the inner peripheral surface of the sorting cylinder (1),

What fell into 4) is the brown rice extraction gutter (2
After being led out to the brown rice sorting wind path (9) by the above 3) and subjected to finish sorting, the rice is taken out of the machine by the brown rice thrower (25).

Those that cannot be lifted by the brown rice receiving gutter (14) flow out from the terminal end of the inner peripheral surface of the sorting cylinder (1) and are returned to the mixed rice lateral gutter (11) by the mixed rice take-out gutter (24). Then, it is lifted again into the mixed rice supply gutter (16) and re-sorted.

In this hulling operation, the tilting adjustment of the brown rice partitioning plate (15) and the hulling sorting plate (22) is performed from the state shown by the solid line to the range shown by the imaginary lines (c) and (d), respectively. Brown rice and paddy trough (1) falling into the brown rice trough (14)
It sorts or separates the paddy falling in 8).

Next, the hulling sorter shown in FIG. 3 will be described. In FIG. 3, the orientation of a pot-hole type rotary sorter (C) installed on the back of the wind selector (B) is shown. A sorting cylinder (1) which is different from that shown in FIG. 1 described above.
The direction of the rotation axis is the same as the direction of the removal roll shaft (3) of the removal unit (A), and the high stream in the downflow direction (Y) of the separation board (2) is on the right side of the hulling sorting device. It is installed next to the protruding part (A) with the lower girder left side, and the other configuration is the same as that of the above-described hulling sorter, so the same reference numerals are given and the description is omitted. .

The brown rice thrower (25) shown in FIGS. 4 and 5 is a bucket type lifter, which can be used to easily check the finished brown rice that has been hulled and taken out. A check plate (28) is provided on the side wall (26) and can be seen through a transparent plate, and a guide plate (28) for guiding the brown rice thrown by the bucket into the check window (27).
And an on-off valve (30) is mounted below the passage (29) formed between the guide plate (28) and the side wall (26), and the on-off valve (30) is connected to the solenoid (31) at a constant cycle. )
, The brown rice staying in the passageway (29) may be viewed from the outside. In addition,
(32) is a return spring.
