Description

DETAILED DESCRIPTION OF THE INVENTION As is well known, a device for separating mixed rice is attached to a hulling device. The device separates the mixed rice into brown rice and unhulled rice, and the brown rice is transferred to the rice milling machine as finished rice, while the unhulled rice is returned to the head of the hulling section for reprocessing.

However, the conventional sorting device is expensive, generates a lot of vibration, and has a large volume.

Therefore, the present invention provides a hulling device equipped with a sorting device that is inexpensive, has almost no vibration, and has a small volume, and is capable of performing an appropriate sorting action with an appropriate supply amount. A sensor is attached to the.

The present invention provides a sorting tube with a rotating pot hole on a horizontal axis in a position near the hulling section, the mixed rice obtained from the hulling section is fed into the sorting tube, and the sorting tube has a specific gravity difference. A brown rice receiving trough is provided so that the brown rice that has sunk to the lower layer can be lifted up and taken out through the pot hole, and a brown rice and unhulled rice are scooped up in a mixed state by the hole in the sorting surface. A mixed rice receiving trough is provided to take out the rice, and one end of the sorting cylinder is installed so that the unhulled rice remaining in the sorting cylinder is returned to the hulling part by taking out brown rice to the brown rice receiving trough and mixed rice to the mixed rice receiving trough. is connected to the supply hopper, and a sensor is installed at a desired position within the sorting tube to detect the amount of grain to be sorted fed into the sorting tube.

To explain with a diagram, (1) is the hulling part (0), which is the hulling part.

On the sorting cylinder side, one end Q41 is attached to the supply hopper (2), and the other end Q5 is located at a position gradually away from the supply hopper (2). Sorting tube a■
As shown in the longitudinal cross-sectional view of FIG. 2, two receiving troughs are provided. One gutter is a mixed wood gutter IIA (Ie
, and another receiving gutter is Brown Rice Bone vJlan. both uke + a
Qfjan are provided in parallel, and the brown rice receiving trough αD is provided closer to the rotation rising side. A screw conveyor α& is installed horizontally on the mixed rice receiving gutter Oe, and the receiving gutter ae forms a drop port a9 at the other end 051 side. A screw conveyor (A) is also installed horizontally on the brown rice receiving gutter aD, and the brown rice receiving gutter αD
The upper end of the discharge gutter QD is connected to the discharge end of the discharge gutter Qυ
opens into a second sorting cylinder installed horizontally below the sorting cylinder a2. Inside the sorting cylinder cla is a finished rice receiving trough (toward).
A receiving gutter (c) is provided so that the finished rice is collected on the supply hopper (2) side and then falls into the discharge gutter c24).
Four screw conveyors are installed above. The second sorting tube (2) is also formed of a thin metal plate σq having a pot hole 11 shown in FIG. The second is finished rice fried grain thrower 1 (5
) is a mixed rice fried grain thrower-1 (to) is a saucer.

Sensors (c) and (to) are provided inside the sorting cylinder α2 and the sorting cylinder, respectively. Sensor Cl11
(to) is attached to the side of the receiving gutter αnL23,
Turns on and off depending on grain pressure. As shown in Fig. 5, the sensor caOI is connected to the alarm 0z via the control box C3111, and is also connected to the motor o1 of the tank (b) suspended at the discharge gutter of the elevator (8). The motor (to) opens and closes the control valve (to).Next, the operation will be described.

The unhulled rice that has fallen from the supply hopper (2) is hulled by a pair of rubber rolls (3), and the mixed rice ab consisting of brown rice a and the unhulled rice flows first into the conveyor (6). The immature rice, which is lighter than the mixed rice ab, flows into the second conveyor (7).

Light rice husks are blown out of the system by the suction blower (5) K suction 1. Mixed rice ab that has flowed into the first conveyor (6)
The elevator (8) is connected to the elevator (8) via a switching valve (not shown).
The rice flows in, is fried by the elevator (8), is supplied from the discharge gutter (toward) to one end of the mixed rice receiving gutter αG, is transported crosswise by the screw conveyor 08, and reaches the other end α9 side. , falls into the sorting beam α2 from the drop opening α bell. Sorting tube a2
Inside, the brown rice a, which has a heavy specific gravity, is stirred by the rotation of the face O2 and sinks to the lower layer, as shown in Figure 6, and the unhulled rice, which is lighter than the brown rice a, floats on top of the brown rice a. Therefore, almost all of the brown rice a fits into the pot hole αυ, and no unhulled rice fits at all. When the sorting cylinder α2 rotates clockwise in FIG. 2, the brown rice a that is deeply fitted into the pot hole αυ reaches the brown rice receiving trough a71 and is taken out as finished rice by the screw conveyor (2). Then, the grains scooped up vigorously by the rotation of the sorting cylinder α2 are sent to the brown rice receiving trough αη.
Jump over it and reach the mixed rice catcher (Is), then go to the sorting tube (1) again.
It is returned within 2. When you take out brown rice a like this,
In Figure 1, the brown rice a is completely absorbed in the m part, and the brown rice a is gone in the ml part, so the mixed rice a and b are used exclusively.
is scooped up and flows into the mixed rice receiving trough α0. Then, when it comes to the part m2, all of the unhulled rice is turned into unhulled rice and returned to the head via the saucer ■.However, the brown rice, the brown rice a in the receiving trough αη, is transported horizontally by the screw conveyor ■. Then, it flows into the second sorting tube @ from the discharge gutter Qυ, where similar sorting is performed, and only brown rice a is scooped out into the receiving gutter (C) and transported horizontally by the screw conveyor 4, and then transferred to the discharge gutter 04. ) is taken out by the thrower (to).0 During this operation, if excessive grain is supplied into the sorting tube 02 (c), this will be detected by the sensor (to),
Power is applied to the control box 011 to sound the alarm c3 such as a buzzer, and the motor @
energize and close the control valve (to). The mixed rice ab discharged from the second sorting cylinder is fried by the thrower which is switched by the switching device. However, the known sorting equipment used a swinging type paddy/brown rice separator to separate the mixture of rice and leftover paddy rice, but the known sorting equipment has the drawbacks of being expensive, vibrating a lot, and having a large volume. However, the present invention provides the following features: (a) A horizontal shaft rotating pot-hole type sorting tube (12k) is provided in the vicinity of the hulling section (1).

b. The mixed rice ab obtained from the hulling section (1) is fed into the sorting tube aZ.

C1 A brown rice receiving channel aD is provided in the sorting tube α2 so that the brown rice a that has settled to the lower layer due to the difference in specific gravity can be scooped up and taken out through the pot hole a11.

Inside d, the sorting cylinder a2 is provided with a mixed rice receiving trough aυ for taking out the brown rice a and unhulled rice scooped up from the pot hole aIIVr in a mixed state Oe, brown rice a The sorting tube tJ2 is arranged so that the unhulled rice remaining in the sorting tube α2 is returned to the hulling part fi+ by taking out the brown rice into the brown rice receiving gutter fi71 and the mixed rice ab into the mixed rice receiving gutter αe.
One end of the shaft is connected to the supply hopper (2).

``A sensor is installed at a desired position in the sorting tube α2 to detect the amount of grain to be sorted fed into the sorting tube O2.
Install.

Since we have created a hulling device that combines the following requirements, all of the above-mentioned known defects can be eliminated, and in particular, there is a sensor in the sorting cylinder that can detect oversupply. Since this is provided, it is possible to eliminate poor sorting due to oversupply.
