JPH0568898A - Air curtain in rice husker - Google Patents

Abstract

PURPOSE:To prevent dust from falling on a shaking type grain sorting device and the member of its periphery and to enhance sorting efficiency. CONSTITUTION:In an air curtain of a rice husker wherein both a rice husking head part 3 and a wind sorting part 9 are provided at the position of the upper part of a shaking type grain sorting device 2, a sirocco fan 28 for the air curtain is provided at the position of the lower part of the rice husking head part 3. The sirocco fan 28 sucks wind from the outside and this wind is passed between the rice husking head part 3 and the grain sorting device 2 and sucked by the suction blower 16 of the wind sorting part 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air curtain for a hulling device.

[0002]

2. Description of the Related Art Conventionally, a swing type grain selecting device provided with a hulling head and a wind sorting unit at an upper position is known.

[0003]

In the above-mentioned known example, the dust falling from the hull head and the wind sorting unit falls on the rocking type grain selecting device and its peripheral members and interferes with the rocking sorting work. There was a problem of becoming.

[0004]

Therefore, according to the present invention, the hulling head 3 and the wind sorting part 9 are provided at the upper position of the rocking type grain selecting device 2, and the hulling head 3 is located below the hulling head 3. A sirocco fan 28 for an air curtain is provided at the position, and the sirocco fan 28 sucks wind from the outside and blows the wind to the hull head 3
It is an air curtain of a hulling device which is made to suck through the suction blower 16 of the wind sorting section 9 through between the and the swing type grain selecting device 2.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 is a square frame frame assembled from steel rods, and an oscillating grain selection device 2 is provided in the frame 1. Reference numeral 3 denotes a hulling head mounted on the frame 1 at a position above the swingable grain-selecting device 2. Inside the hulling head 3, a pair of hulling rolls 4 and 5 are provided. Reference numeral 6 is a feeding roll, and 7 is a supply hopper.
On a side portion of the hulling head 3, a tension elevator 8 is provided to feed the rice grain to the feeding hopper 7. A wind sorter (aspirator) 9 is provided beside the hulling head 3 on the frame 1 and above the rocking type grain selecting device 2. Reference numeral 10 denotes a wind selection room of the wind selection unit 9. 11 is a mixed rice drop opening, 12 is a distribution part of the rocking type grain selection apparatus 2, and 13 is a sorting board of each stage.

The outlets 14 and 1 are provided on both the left and right sides of the wind selection chamber 10.
4 is open, and the outlets 14 and 14 have left and right outlets 15 and 1, respectively.
The upper ends of 5 are connected. The blowout passages 15 and 15 are joined together on the front side, and are connected to a suction port 17 of a suction blower 16 provided below the wind sorting unit 9. Reference numeral 18 denotes an outlet pipe of the suction blower 16, which is extended to the outside of the room.

At the lower end of the air-selecting chamber 10, a conveyor 19 that is biased to one side is provided, and at the lower part of the end of the conveyor 19, a valve 21 that is rotated by a motor 20 is provided, and the lower cylinder of the valve 21 blows out. A connection opening is made to the pipe 18.

A sirocco fan 28 for an air curtain is provided below the hulling head 3. The sirocco fan 28 sucks wind from the outside, passes the wind between the hulling head 3 and the swing type grain selection device 2, and the suction blower 16
To suck. In addition, 22 is a port, 23 is a mixed rice elevator, 24 is a paddy rice outlet, 25 is a finished rice outlet, 26 is a finished rice elevator, and 27 is a scrap rice sorter.

[0009]

[Operation] Next, the operation will be described. When paddy rice is supplied from the pick-up port 22, it is fried by the pick-up elevator 8 and flows into the supply hopper 7, and is fed between the hulling rolls 4 and 5 by the take-in roll 6 to be hulled. Light weight foreign matter among the hulled matter passes through the air outlets 14, 14 from the wind selection chamber 10 and blows out from both air outlets 1
Then, the gas flows into the suction blower 16 through the suction port 17 and is blown away from the blow-out pipe 18. In the wind selection chamber 10, a slightly heavy foreign substance falls, which is laterally transferred by the conveyor 19 and gradually falls by the valve 21 rotated by the motor 20 to blow out the blowout pipe 18.
It merges inside and is discharged. Grain drops from the mixed rice drop port 11 and flows into the distribution unit 12, is distributed and supplied to the multi-stage sorting board 13 and is swing-sorted, and the finished rice flows from the finishing rice outlet 25 into the finishing rice elevator 26, Raised and scrapped rice sorter 27
And the waste rice is removed. The unhulled rice is returned from the unhulled rice outlet 24 to the sprue 22 and is reprocessed. The mixed grains that are not separated are mixed rice elevator 23 from the mixed rice outlet (not shown).
To be fried and returned to the distribution unit 12 for reprocessing.

In the above operation, dust from the hulling head 3 and the wind sorting unit 9 falls on the rocking type grain selecting device 2 and dusts the rocking type grain selecting device 2 and those around it. According to the present invention, a sirocco fan 28 for an air curtain is provided at a position below the hull head 3 so that the wind sucked from the outside is provided between the hull head 3 and the swing type grain selection device 2. Since the suction blower 16 is sucked through, the dust is not applied to the swing type grain selection device 2 and the peripheral members.

[0011]

The above-mentioned known example has a problem that dust from the hulling head and the wind sorting section reaches the rocking type grain selecting apparatus and its surrounding members. However, according to the present invention, the hulling head 3 and the wind selecting part 9 are provided at the upper position of the rocking type grain selecting device 2, and the sirocco fan for the air curtain is provided at the lower position of the hulling head 3. 28 is provided, and the sirocco fan 28 sucks wind from the outside and allows the wind to be sucked by the suction blower 16 of the wind sorting unit 9 through the gap between the hull head 3 and the swing type grain selecting device 2. Since the air curtain of the hulling apparatus is used, the hulling head 3, the wind sorting section 9, and the swing type grain selecting apparatus 2 are completely cut off by the sirocco fan 28. The grain device 2 itself is protected from dust, and a hygienic effect is achieved.
