Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice husk storage, which is installed in a barn, a rice center, a country elevator, or the like, and is used to temporarily store rice hulls blown from a huller and sequentially take out the rice husks. .

[0002]

2. Description of the Related Art Conventionally, in a grain drying and preparation facility, there has been a problem with the processing of rice husks generated during rice hulling, and the amount of the rice husks is quite large. Housed inside is the mainstream.
For example, the rice husk storage shown in FIG. 6 is configured such that an upper part is a cylindrical silo 101, and a garage 102 is provided at the lower part of the cylindrical silo 101, through which a truck for carrying out rice husks enters and leaves, and discharges the rice husk. The rice husk outlets 104 and 105 are formed in the flat bottom surface 103 (see FIG. 7).

Further, the rice hull storage silo disclosed in Japanese Utility Model Laid-Open Publication No. 57-171836 has a funnel-shaped lower part of a silo, and an air nozzle for blowing compressed air for collapsing a bridge at a silo discharge port. It is a thing.

[0004]

In the case of the rice husk storage shown in FIG. 6, since the accumulation height of the rice husk is high, the rice husk is accumulated in the cylindrical silo 101 under its own weight in a compressed state. For this reason, the pressure of the rice hulls is uniformly applied to the central portion and the peripheral portion of the silo bottom surface 103. There is a risk that these rice husks cannot be discharged because they are difficult to flow and form a bridge. Referring to FIG. 5, it can be seen that the chaff is easily discharged at the position of the chaff discharge ports 104 and 105 in the height direction, but the chaff is less likely to flow near the silo side wall 108 and tends to be in a bridge shape.

In Japanese Utility Model Laid-Open No. 57-171836, an air nozzle for blowing compressed air to collapse a bridge formed on a silo side wall is provided.
There was a disadvantage that the cost was high.

[0006] In view of the above problems, it is a technical object of the present invention to provide a rice husk storage that can completely discharge stored rice hulls without causing a bridge near a silo side wall.

[0007]

In order to solve the above-mentioned problems, the present invention provides a technique in which a pressure buffer chamber having a floor surface having an area larger than the cross section of the rice husk storage is provided below the standing rice husk storage. Tactics were taken. As a result, even when the rice husk is stored in the rice hull storage and the pile height is increased, the pressure due to the dead weight of the rice husk is reduced in the pressure buffer chamber. That is, in the pressure buffer chamber, since the floor area is larger than the cross-sectional area of the rice hull storage, the pressure acting on the side wall of the rice hull storage is lost, and the compression of the rice husk is reduced.

[0008] Since the pressure buffer chamber is provided with a roof having a gradient that is gentler than the angle of repose of the rice hulls, the rice hulls spread laterally in the pressure buffer chamber and are deposited at an arbitrary gradient (angle of repose). Will be. When discharging the rice hulls, opening the shutter on the floor of the pressure buffer chamber collapses the angle of repose of the rice hulls, and the rice husks that have accumulated high in the rice hull shed flow down like an avalanche, forming a bridge near the side wall of the rice husk storage. Will not cause.

Done. The pre-dried grains are conveyed to a supply unit of the silo graining machine 10 via a horizontal conveying device (not shown) provided below the drying device, and are sent through the silo graining machine 10 and the horizontal conveying device 39. Thus, it is supplied to each silo 2 and stored. The pre-dried grains are taken out of the silo 2 and circulated through the drying device in the same manner as described above, and subjected to main drying until the finished moisture is obtained. The dried kernels are passed through the silo fryer 10 and the horizontal transport device 39. Then, it is supplied to the silo 2 and stored for a certain period.

The grains during storage can be stored in storage silo 2 if necessary.
, And the roughing machine 23
Is again supplied to the paddy tank 40 and is weighed by the paddy weighing device 41 further below. The weighed grains are hulled by a huller 20 and separated into rice, brown rice and chaff, and brown rice as a product passes through a grain sorter 24 and a brown rice scale 22 to the product storage 7 by the product transport device 14. Conveyed.
The paddy and the mixed rice of the paddy and brown rice are supplied to the paddy sorter 21 for re-sorting. It is preferable that the rice husks generated in the hulling process be sequentially accumulated and stored in the rice husk storage 5 by an air blower.

Although the rice hulls are sequentially deposited in the rice hull storage 5, even when the accumulation height of the rice husks is increased, the pressure due to the dead weight of the rice husks is reduced in the pressure buffer chamber 26. Referring to FIG. 4, in the pressure buffer chamber 26, since the floor surface 30 has a larger area than the cross section of the rectangular cylindrical rice hull storage 25, the pressure acting on the side wall of the rice husk storage 25 is lost, and the rice husk is eliminated. Compression is alleviated. Then, the rice hulls spread leftward in the drawing of the pressure buffer chamber 25 and are deposited at an arbitrary gradient (angle of repose α). When discharging the rice hulls, when one of the shutters 34 and 35 of the floor surface 30 of the pressure buffer chamber 26 is opened, the angle of repose α of the rice hulls collapses, and the rice hulls that have been highly accumulated in the rice hull storage 25 become avalanches. It does not flow down and does not form a bridge near the side wall of the rice husk storage 25. The rice husks are loaded on the loading platform of the truck that has entered through the exit 38,
It will be transported to the rice husk processing facility.

In this embodiment, an example in which the rice husk storage is applied to a country elevator has been described. However, the present invention is not limited to this, and can be applied to a barn such as a farmhouse or a rice center.

[0020]

As described above, according to the present invention, a pressure buffer chamber having a floor surface having an area larger than the cross section of the rice husk storage is provided below the standing rice husk storage. Even if the pile height is increased, the pressure due to the dead weight of the rice hulls is relieved in the pressure buffer chamber, and when the rice husk discharge port is opened, the rice husks flow down in an avalanche-like manner, causing a bridge near the rice husk storage side wall. There is no.

Further, since the pressure buffer chamber is provided with a roof having a gradient that is gentler than the angle of repose of the rice hulls, the rice hulls spread laterally in the pressure buffer chamber and are deposited at an arbitrary gradient (angle of repose). Will be.

Further, since the pressure buffer chamber is provided with a door through which a worker can enter and leave, after the chaff is discharged by its own weight, the worker can easily enter the pressure buffer chamber and scrape out the remaining chaff. it can.

Since the rice hull storage is provided with a plurality of viewing windows, the stored amount of the rice husk can be visually checked.
