Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain fryer for a hulling sorter.

[0002]

2. Description of the Related Art Conventionally, in a hulling sorter, there is known a thrower in which grain is raised by jumping a wheel. Moreover, the hulling sorter of FIG. 1 is also known. In FIG.
A is a hulling wind selection unit, B is a swing sorting unit, and a hulling wind selection unit A has a pair of left and right rubber rolls axle mounted on the upper part, and a wind selection unit b that air-selects hulling below the rubber rolls a. To form In the swinging sorting unit B, a sorting device d in which sorting plates c are stacked in multiple stages of 5 to 6 stages is provided, and a bucket elevator e is provided behind the hulling wind sorting unit A to fry the mixed rice, A storage tank f is provided at the discharge port of the bucket elevator e, and is equally distributed to the swing sorting plates c of each stage via the distribution device g. A supply hopper h is provided above the hulling wind selection unit A, and when rice is supplied to the supply hopper h, hulling is performed by a rubber roll a, and hulling that is air-selected by the breeze unit b is blown by a blower i. The hulled material is fried by a bucket elevator e, flows into a storage tank f, and is supplied from a distributing device g to a sorting device d. In the sorting device d, the rice is separated into paddy rice, mixed rice, and brown rice by rocking, the brown rice is taken out as a finished rice by the finishing rice thrower j, and the mixed rice is returned to the bucket elevator e to be re-sorted. Is the feed hopper h
It is returned to and hulled again.

[0003]

The above-mentioned well-known finished rice thrower is also called a jumping thrower because it jumps up by the rotation of the impeller, but the rising wind caused by the rotation of the impeller exhausts air from the grain discharge port. Therefore, there is a problem that a large amount of dust is scattered.

[0004]

The object of the present invention is to prevent the thrower from scattering dust.

[0005]

Therefore, according to the present invention, the upper part discharge portion of the finished rice thrower is formed such that the grain is discharged from a grain discharge port below the bent flow path, and the bent flow path is formed by the bent flow path. When the grain remains, the wind of the impeller of the finished rice thrower is not exhausted from the grain outlet, but is exhausted from a separately formed return airway, and is connected to the return airway. The induction air path is a hulling sorting device connected to the suction port of the hulling waste discharge blower in the wind selection room of the hulling unit.

[0018]

Next, the operation will be described. The rice is thrown into the supply hopper 30, and the opening and closing shutter of the supply hopper 30 is opened by an arbitrary method.
The rice husk is sucked in the air culling path 35 in the air culling chamber 68 and discharged by the rice hull discharge blower 3, and the mixed rice that has been blasted falls into the mixed rice receiving gutter 38 and is sent back by the conveyor 39 to be mixed. The rice is fed to the lower end of the rice bucket elevator 5, fried, and stored in a fixed storage tank 6. Second trough 4
The second product that has dropped to 1 is fried in the second thrower 43 and returned to the paddy receiving trough 44. In this case, the upper and lower inclined rolls 33 and 34 are adjusted by rotating the rotary handle 63 so that the upper and lower inclined rolls 33 are adjusted to an optimal interval, and are hulled. In some cases, foreign matter such as a tool may be supplied. In this case, the abnormal handle 66 is pulled to widen the interval to prevent breakage.

When the shutter of the fixed storage tank 6 is opened as required, the mixed rice is supplied from the fixed storage tank 6 to the distribution device 8 and moves to the dividing port 20 by the vibration of the bottom plate 19 of the distribution device 8, and the divided rice is divided. It is divided at the mouth 20 and supplied to the sorting plate 9 of each stage. The sorting plate 9 is swung right and left by the cam wheel 12 rotated by the motor 13, but a large number of swinging projections which can swing to the right in the drawing are formed on the plate surface of the sorting plate 9, so that the specific gravity is heavy. Brown rice moves to the right side in the figure, and rice with a low specific gravity moves to the left side in reaction, and mixed rice that is not separated is distributed in the center. The brown rice gathered in the brown rice discharge section 23 on the right side falls into the brown rice outlet 48, is transported rightward by the one-axis opposite spiral 51, flows into the part of the impeller 53 of the finished rice slower 4, is jumped up and taken out. You. In this case, a bent downflow path 56 is formed at the upper end discharge section 55a of the finished rice slower 4 as shown in FIG. 7, and a grain discharge port 55 is formed below the bent downflow path 56. When the grain accumulates, the wind of the impeller 53 stops at the grain, so that the wind is not exhausted to the grain discharge port 55, but is returned from the return air path 57 communicating with the bent downflow path 56, and the rice seeds are discharged through the induction air path 57a. The air is exhausted by the impeller 36 of the blower 3.

The sorting state of the sorting plate 9 can be seen through the see-through window 17, but if the grain is too close to the brown rice discharge section 23 side, the switch 18 must be turned off because the right and left inclination is not enough. Operate the first adjusting motor 1 of FIG.
4 is turned on, the screw rod 15 is rotated to raise the right side of the selection plate 9, and in the opposite case, the first adjustment motor 14 is reversed to lower the right side of the selection plate 9. Further, when a little rice is mixed in the brown rice extracted by the finished rice thrower 4, since the position of the first partition plate 21 is too close to the left, the second adjustment motor 26 is energized. Screw rod 2
7 is rotated to move the first partition 21 to the right.

In the above sorting, the mixed rice dropped from the mixed rice outlet 49 is moved to the left by the one-axis opposite spiral 52, collected in the mixed rice receiving trough 38, and is fried by the mixed rice bucket elevator 5. Further, the paddy rice taken out from the paddy rice outlet 50 is collected in the return paddy trough 44, returned to the supply hopper 30 by the return thrower 54, and crushed again.

[0022]

According to the present invention, the upper part discharge part of the finished rice thrower is formed so that the grain is discharged from the grain discharge port under the bent flow path, and the bent flow path is formed when the grain stays there. The wind of the impeller of the finished rice thrower is not exhausted from the grain exhaust port, but is exhausted from a separately formed return air path, and the induction air path connected to the return air path is a hulling. Hulling sorting equipment connected to the suction port of the hulling waste discharge blower in the wind selection room
The wind of No. 3 is stopped by the finished finished rice, and is suctioned and exhausted by the paddy discharge blower 3 in the wind selection chamber 68 of the paddy section 1 from the separately formed return duct port 57 through the guide duct 57a. , Sanitary.
