Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a distribution device for a multi-stage oscillating sorting device.

In order to increase separation efficiency, the oscillating sorting device has sorting plates stacked in multiple stages of 4 to 5 stages.
Therefore, each stage of sorting plate is equipped with a distribution device for evenly distributing the mixed rice.

In the conventionally known distribution device, a distribution feed gutter is attached to the feed portion of the oscillating grain sorting device, and a partition plate parallel to the grain flow direction is attached to the bottom surface of the distribution feed gutter to form a distribution flow path. Then, it was distributed evenly to each stage of sorting board.

However, in the known method, the mixed rice is not divided evenly, and a large amount of mixed rice flows into the distribution channel on the center side of the supply gutter, or a large amount of mixed rice flows into the distribution channels on both the left and right sides of the supply gutter. It was something to do.

Therefore, in the present invention, the partition plate is formed in a structure that can be freely adjusted in the left-right direction, so that the amount of grain flowing through each distribution channel is made equal.

As mentioned above, if the partition plate is made adjustable, it is difficult to adjust the zero position, so the present invention has been devised in this respect as well.

Therefore, in the present invention, the sorting plates are integrally provided in multiple stages, a distribution supply gutter is provided above the group of sorting plates, and a distribution flow path leading to the sorting plates of each stage is provided in the discharge part of the distribution supply gutter. In the device, the plurality of partition plates forming the distribution flow path are formed by partition plates made of leaf springs fixed at right angles to the fixed part, and the partition plates are adjustable through a fitting part with a play width. This is a grain distribution device configuration of a multi-stage swing type sorting device in which a bolt is attached and the curvature of the partition plate is adjusted by rotating the bolt.

To explain with reference to the drawings, reference numeral 1 is a vertical elevator for supplying unhulled rice, and a unhulled rice charging hopper 2 is provided at the lower part of the elevator, and the upper end of a supply pipe 3 is attached to the upper part of the hopper 2. The lower end of the supply pipe 3 is connected to a hopper 5 provided at the upper end of the hulling device 4 provided on the side of the elevator 1.
Let's face it.

An on-off valve 6 is provided at the bottom of the hopper 5, and a feed roll 7 is pivoted below the on-off valve 6. A fixed hulling roll 8 and a movable hulling roll 9 are provided below the feeding roll 7. The hulling rolls 8 and 9 are arranged diagonally above and below, with the fixed side at a higher position.
10 is a discharge chamber for the hulling rolls 8 and 9.

A winnowing section 11 is provided below the hulling device 4. 1
Reference numeral 2 denotes an inverted-hat type guide plate, and the mixed rice flowing down from the discharge chamber 10 is transferred to the wind sorting section 1 by the inverted-hat type guide plate 12.
Supply within 1. Below the upside-down guide plate 12,
A blower fan 13 is provided. A wind selection chamber 14 is formed on the side blowing side of the fan 13. Wind selection room 14
A suction blower 15 is provided at the terminal end. A hopper 16 is formed below the wind selection chamber 14, and one of the members of the hopper 16 is an on-off valve 18 whose upper end is pivoted with a shaft 17. A swing-type sorting device 19 is provided at the bottom of the wind sorting section 11 to separate the mixed rice into paddy rice and brown rice.

A distribution supply gutter 20 is installed at the top of the swing type sorting device 19.
will be established. The distribution supply gutter 20 is fixed to a sorting plate 21 provided at its lower part. 22 is a guide plate provided above the supply side 23 of the distribution supply gutter 20. A weir 25 is provided on the supply side 23 of the bottom plate 24 of the distribution supply gutter 20.
will be established. The weir 25 is used to spread the mixed rice in the width direction on the bottom plate 24 so that it is evenly distributed and inflowed.

A discharge port 27 with a full width is formed on the discharge side 26 of the distribution supply gutter 20. The discharge ports 27 are arranged equally in the length direction by the number of partition members 2 corresponding to the number of the sorting plates 21.
8, and a distribution channel 29 leading to each sorting plate 21 is provided.

Each partition member 28 includes a partition plate 30, an angle member 32, an engaging member 38, and the like. The partition plate 30 is formed of a leaf spring, and its base end is fixed to an angle member 32 fixed to the front side wall 31 of the discharge side 26 with a stopper 33. Since the partition plate 30 fixed to the angle member 32 with the fasteners 33 is a spring member, it is perpendicular to the front side wall 31. A nut 34 is welded to the front side wall 31, and a bolt 35 is screwed into the nut 34 in parallel with the partition plate 30. A small diameter portion 36 is formed at the tip of the bolt 35, and a flange portion 44 is formed at the tip of the small diameter portion 36, and an engagement member 38 fixed to the side surface of the intermediate portion of the partition plate 30 with a stopper 37 is engaged. The small diameter portion 36 is fitted into the insertion hole 40 formed in the mating piece 39.

In this case, the thickness of the small diameter portion 3 is greater than the thickness of the engagement piece 39.
Since the length a of 6 is considerably longer, in the state shown in FIG. 4, the partition plate 30 is elastically stretched and is perfectly perpendicular to the front side wall 31.

The sorting plate 21 is formed in multiple stages of 4 to 5,
It is attached so as to be able to swing back and forth by a swinging support rod 42 that is attached to a shaft 41 provided in the front and back direction. 43 is a control plate for the amount of unhulled rice discharged.

Next, we will discuss the effect.

When the unhulled rice as a raw material is supplied to the unhulled rice input hopper 2, it ascends in the elevator 1 and is stored in the hopper 5 through the supply pipe 3.

By opening the on-off valve 6, the grain stored in the hopper 5 is fed out by the feed roll 7, fed between the hulling rolls 8 and 9 which are diagonally arranged in an upper and lower relationship, the grain is hulled, and then sent to the discharge chamber 10. The rice husks are discharged into the air, fall into the wind selection chamber 14 via the inverted-ha type guide plate 12, are wind-selected by the ventilation fan 13 and the suction blower 15, and are stored in the hopper 16.

Then, when the on-off valve 18 opens to a desired degree,
The supply side 2 of the distribution supply gutter 20 by reflecting the guide plate 22
3. The distribution supply gutter 20 has a sorting plate 21
Therefore, when it crosses the weir 25, it gradually spreads in the width direction and reaches the discharge port 27.

In this case, check the grain distribution state on the distribution feed gutter 20 with the naked eye or with a sensor, and if it is uniformly distributed, hold the knob of the adjustment bolt 35 and rotate it to the right or left.
When the small diameter portion 36 reaches the state shown in FIG. 4, the knob becomes lighter, so you can tell that state. At this time, the partition plate 30 is completely perpendicular to the front side wall 31, and the partition plate 30 is evenly distributed to each distribution channel 29. It is. If the distribution state is uneven, check the distribution state of the mixed rice and turn the adjustment bolt 35 to bend the partition plate 30 left and right to distribute the mixed rice evenly into each distribution channel 29. lead

Thus, the evenly distributed mixed rice reaches the distribution channel 29 and is sorted by the sorting plates 21 at each stage.

Conventionally, when sorting plates are arranged in multiple stages, a distribution device is required to evenly distribute the materials to each stage. Various types of distribution devices are conceivable, but generally a method is used in which the flow path is divided in the width direction using a partition plate.

However, sometimes the distribution of grain is not uniform in the width direction, and in that case, the partition plate is adjusted by rotating left and right depending on the flow on the distribution feed gutter. However, in this case as well, there was a drawback that the center was difficult to find.

However, the present invention provides a method in which sorting plates are integrally provided in multiple stages, a distribution supply gutter is provided above the group of sorting plates, and a distribution flow path leading to the sorting plates of each stage is provided in the discharge part of the distribution supply gutter. In the above, the plurality of partition plates forming the distribution flow path are formed by partition plates made of leaf springs fixed at right angles to the fixed part, and the adjustment bolts are connected to the partition plates through fitting parts with play width. Since the grain distributing device of the multi-stage swing type sorting device is configured so that the curvature of the partition plate is adjusted by attaching the bolt and rotating the bolt, it is possible to easily center any partition plate accurately.
