Description

[Detailed description of the invention] The present invention is particularly effective when used in a hulling and sorting device, etc., in which a hulling device, a grain frying device, and a rocking specific gravity sorting device are connected in a related manner. be.

During the hulling operation in the hulling device, it is not expected that all the grains will be completely hulled at once, but the hulling operation is carried out so that there will be a slight amount of unhusked residue.

Therefore, the hulled product is a mixture of unhusked rice and unhusked rice, and a separation device is required.

Two types of mixed grain separation devices for unhulled rice and brown rice are known: a lightweight sieve-type Mangoku device and a heavy-duty rocking-type specific gravity sorting device.

The present invention relates to a rice hulling sorting device using the latter swing type specific gravity sorting device.

The former type of sieve-type mangoku has a gravity flow type structure, and the discharge side of the mangoku is located at a very low level, so it is moved to the next working machine using a specially installed grain lifting device.

However, as is known, the separated unpolished rice in the rocking type gravity sorting device is separated by being stirred up on the high side of the device, so even if there is no special grain lifting device, the finished unpolished rice can be transferred to the next working machine. can be supplied.

For example, if a rotary rice separator is installed below the brown rice outlet, the brown rice discharged at a high position can be supplied to the rice separator to separate waste rice from the brown rice.

In this case, if a take-out gutter is attached to the brown rice take-out port of the swing-type specific gravity sorting device, which can be further guided by the swing of the device, the brown rice can be supplied to, for example, a rice sorting machine installed nearby. This makes handling easier.

However, if the take-out gutter is left protruding to the side, it will get in the way during transportation, so in the present invention, it can be taken in and out freely, and the mixed grains of unhulled rice and brown rice can be shaken up and down at an angle. In a grain sorting device that separates grains by motion, a separating brown rice take-out gutter whose bottom surface is a step-like delivery surface is provided on the discharge side of the sorting device so as to protrude sideways, and the take-out gutter is removable or This is a structure of a grain extracting device in a grain sorting device which is formed to be foldable or to be freely removable.

To explain the overall configuration using diagrams, in Figure 1, 1
1 is a hulling device, in which a supply hopper 2 for supplying the raw material, unhulled rice, is installed on the upper surface, and a pair of hulling rolls 3, 3 are mounted on the lower part of the hopper 2; A suction air passage 4 for rice husks, etc. is formed in the lower part, and a mixed grain receiving trough 5 for unhulled rice and brown rice is provided at the lower part, and a grain feeding spiral 6 for transversely transporting the mixed grains is mounted on the receiving trough 5. do.

Both ends of the spiral 6 protrude from the case of the hulling device on both sides, and an elevator 7, which is a grain lifting device, is provided on the protruding side of one end to face the protruding end of the spiral 6 (the protruding end of the other end is a form the rice receiving area).

A case 8 which also serves as an abutment is adjacent to the side of the hulling device 1, and the case 8-. A rocking type specific gravity sorting device 10 is mounted on L-, via a rocking device 9.

One side of the device 10 faces the vicinity of the supply hopper 2, and the opposite side to the - side is made higher in height than the - side to form a rocking L side 11 (see Fig. 2), and The side near the elevator 7 is a supply side 12 and the opposite side is a discharge side 13, and the supply side 12 is made higher than the discharge side 13 and inclined.

14 is the sorting board of the oscillating specific gravity sorting device, as shown in the figure, there are four
It is formed in the form of multiple stone steps.

On the discharge side 13, there are about two or three partition plates 15°15.
... is provided, and the outlet near the shaking upper side 11 formed by providing the partition plate 15 is the brown rice outlet 16, and the unhulled rice outlet 1 is located on the opposite side closer to the shaking side 17.
8, and in the middle is a mixed grain outlet 19 for unhulled rice and brown rice.
form.

A vibrating conveyor 20 is attached to the portion of the brown rice discharge port 16 where the brown rice falls, and a take-out gutter 21 is connected to the swinging side 11 of the conveyor 20.

The extraction gutter 21 protrudes laterally from the device 10, but is formed in a structure that allows it to be moved in and out.

The simplest structure is that it is detachable, but with a detachable structure, it is difficult to find a place to store it after it is removed, so the embodiment shown in FIG. 4 is designed to be foldable.

That is, a take-out gutter 21 with a step-like delivery surface 22 at the bottom is foldable between the working position shown by the solid line and the storage position shown by the temporary line, and is fixed by a stopper 23 or 24 attached to the side wall.

Fig. 5 shows a device that can be taken in and out at will, and is pulled out for use and pushed in for storage.

A gutter 25 inclined toward the swinging side 17 is attached to the F portion outside the mixed grain discharge L] 19, and a mixed grain falling port 26 is formed by opening the gutter 25 near the swinging side 17.

A storage tank 2 is installed at the upper discharge part of the elevator 7, which is a grain lifting device.
7 is installed, and the lower part of the storage tank 27 is a distribution transfer gutter 28.
Opens on the supply side of the

The distribution transfer gutter 28 has an integral structure with the sorting device 10,
It swings together with the sorting device 10.

In the figure, 29 is a magnifying glass, 30 is a paddy rice return path, 31 is a return gutter,
32 is a rice sorting machine.

Next, we will discuss the effect.

After each part is rotated by a motor installed at an arbitrary position, unhulled rice is supplied to the supply hopper 2. When the unhulled rice passes between the hulling rolls 3 and 3, it is hulled.
Light-weight rice husks are removed by suction, and the mixed grains of unhulled rice and brown rice are received by the receiving trough 5, transported outside the machine by the grain feed spiral 6, etc., and flow into the elevator 7.

The mixed grains fried by the elevator 7 are temporarily stored in the storage tank 27, and then distributed in fixed amounts through the distribution gutter 28.
is supplied to the sorting board 14-L of each stage.

Since the sorter 14 is moved obliquely up and down in the W direction by the swinging device 9, the grains are separated into three grains: brown rice, unhulled rice, and mixed grains of brown unhulled rice, and flow out from each outlet.

In this case, the boundaries between the separated grains are not clearly defined, so they are carefully observed through the magnifying glass 29 and adjusted by moving the partition plate 15 left and right.

Since the magnifying glass 29 is attached to the partition plate 15, it moves together with the partition plate 15, and therefore adjustment can be made very easily.

The separated unhulled rice flowing out from the unhulled rice outlet 18 is returned to the supply hopper 2 through the return path 30 and circulated together with new raw materials to be subjected to the hulling action again, and a large amount of unseparated brown rice and unhulled rice are mixed together. After the grains flow out from the mixed grain discharge port 9, they flow through the gutter 25 and are returned through the drop port 26 by the grain feeding spiral 6.

The brown rice discharged from the brown rice take-out [] 16 falls onto the vibrating conveyor 20, and gradually moves to the shaking side 1 due to the stirring action of the conveyor 20, which vibrates in the W direction together with the device 10.
However, in the present invention, since a take-out gutter 21 with a step-like delivery surface 22 at the bottom is attached continuously to the vibrating conveyor 20, the take-out gutter 21 is guided further to the side and is moved in the vicinity thereof. The rice is supplied by dropping from the direct-E position of the supply port of the installed rice sorting machine 32, etc.

When the above work is completed, if the extraction gutter 21 is made to protrude to the side of the bond, when transporting the aircraft, and
This can cause damage when working around the machine, so in the case of the embodiment shown in Figure 4, remove the upper clasp 23, rotate it to the bottom of the machine, fold it, and secure it with the clasp 24. Therefore, the aforementioned defect can be eliminated.

Further, in the case of the embodiment shown in FIG. 5, the above object can be achieved because the device is stored inside when it is pushed in a little.

The present invention has the above-mentioned structure and function, and in particular, in a grain sorting device that separates mixed grains of unhulled rice and brown rice by diagonal up-and-down rocking, the discharge side of the sorting device has a bottom surface with a stepped delivery surface. A grain removal gutter in a grain sorting device is provided in which a separated unpolished rice removal gutter is provided to protrude laterally, and the removal gutter is configured to be detachable, foldable, or removable. Since the step-like delivery surface 22 is formed on the bottom of the gutter 21, brown rice can be guided even if the ejection gutter 21 protrudes sideways for a long time. Not only can it be dropped to the optimum position of the supply port, but also because the take-out gutter 21 is configured to be detachable, foldable, or come in and out, it has the effect of being able to be stored out of the way after work.
