Abstract

PURPOSE:To perform the classification of chaff without strengthening an air flow in an air classification chamber by opening blow-off ports on the left and right sides of the air classification chamber to collect the chaff accumulated in the lower part of the air classification chamber to one side using a conveyor and to drop the chaff into a blow-off pipe through a valve rotating by a motor. CONSTITUTION:An oscillating chaff classification device 2 is placed on a square frame 1, and a huller top 3 is installed on the frame 1. A charging lift 8 for supplying unhulled rice to a supply hopper is installed on the side of the huller top 3. An aspirator 9 is also installed on the side of the huller top 3 on the frame 1. The aspirator 9 is equipped with an air classification chamber 10 having blow-off ports on the left and right sides. Left and right blow-off passages 15 are connected to the respective blow-off ports and they are joined at their tips. The joined passage is connected to the suction port 17 of a blower 16, and a conveyor 19, which collect the chaff to one side, is installed at the lower end of the air classification chamber 10. A valve 21 is fixed at the lower end part of the conveyor 19, and the lower cylinder of the valve 21 is connected to a blow-off pipe 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind sorting device for a hulling device.

[0002]

2. Description of the Related Art Conventionally, an air outlet that is open on one side of a wind selection chamber,
The air outlet comprises an air outlet connected to the upper end of the air outlet, a suction blower provided at a lower position of the air selection chamber, and an air outlet pipe extending longer than the air inlet of the air blower. What is connected to the mouth is public.

[0003]

The above-mentioned known example has a structure in which the air outlet is open on one side of the air-selecting chamber, so that there is a problem in that the air-selecting becomes uneven. Further, since the blowout path having the upper end connected to the blowout port is connected to the suction port of the suction blower,
Rice husks and the like sometimes remained at the bottom of the wind-selected room. When the wind was made strong so that rice husks and the like did not remain at the bottom of the wind selection room, the wind was too strong, which adversely affected the selection.

[0004]

Therefore, according to the present invention, the air outlets 14 and 14 which are opened on both the left and right sides of the air selection chamber 10, and the left and right air outlets 15 and 1 whose upper ends are connected to the air outlets 14 and 14, respectively.
5 and a suction blower 1 provided below the wind selection chamber 10.
6 and a blow-out pipe 18 extending longer than the suction blower 16
The blow-out passages 15 and 15 are connected together at the front side to the suction port 17 of the suction blower 16, and a conveyor 19 is provided at the lower end of the wind-selecting chamber 10 to shift to one side. A valve 21 that is rotated by a motor 20 is provided below the end of the valve 21, and the lower cylinder of the valve 21 is the blowout pipe 1
8 is a wind-screening device for a hulling device that is connected to and opened at 8.

[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. 3 is a hull head mounted on the frame 1, and a pair of hull rolls 4 and 5 are provided in the hull head 3. Reference numeral 6 is a feeding roll, and 7 is a supply hopper. A hopper 7 for supplying paddy rice to the sides of the paddy head 3
A squeeze elevator 8 is provided for supplying A wind sorting unit (aspirator) 9 is provided beside the hulled head 3 on the frame 1. 10 is a wind selection room, and the hulling part blows up as shown by arrow a. 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. 2
2 is a spout, 23 is a mixed rice elevator, 24 is a paddy rice exit, 2
5 is a finish rice outlet, 26 is a finish rice elevator, and 27 is a scrap rice sorter.

[0008]

[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 foreign matter among the hulled material is blown up in the direction a, flows into the blowout passages 15 and 15 from the wind selection chamber 10 through the blowout openings 14 and 14, and together, the inside of the suction blower 16 from the suction opening 17. And is blown away from the blowoff pipe 18. In the wind selection chamber 10, a slightly heavy foreign substance falls and is transferred laterally by the conveyor 19 to the motor 2
A valve 21 rotating at 0 causes the valve 21 to gradually drop, merge into the blow-out pipe 18 and be discharged. Grains are mixed rice drop mouth 1
It drops from 1 and flows into the distribution unit 12, and the multi-stage sorting board 13
And is sorted and supplied to the finished rice outlet 25, the finished rice flows into the finished rice elevator 26, rises and is scraped 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.

[0009]

The known example has a problem that the air selection is uneven because it has a structure in which the air outlet is opened on one side of the air selection chamber. In addition, since the air outlet having the upper end connected to the air outlet is connected to the suction port of the suction blower, rice husks and the like may remain in the lower part of the air selection chamber. When the wind was made strong so that rice husks and the like did not remain at the bottom of the wind selection room, the wind was too strong, which adversely affected the selection. However, according to the present invention, the air outlets 14 and 14 that are opened on both the left and right sides of the wind selection chamber 10, and the air outlet 1
Left and right outlets 15 and 15 with upper ends connected to 4 and 14,
A suction blower 16 provided at a position below the wind selection chamber 10,
The blower pipe 18 extends longer than the suction blower 16, and the blowout passages 15 and 15 are connected to the suction port 17 of the suction blower 16 together on the front side, and are connected to the lower end of the air selection chamber 10. Is provided with a conveyor 19 that is biased to one side, and a valve 2 that is rotated by a motor 20 is provided below the end of the conveyor 19.
1 is provided, and the lower cylinder of the valve 21 is the wind selecting device of the hulling device that is connected and opened to the blow-out pipe 18.
Since the outlets 14 and 14 are on both sides and the rice husks accumulated in the lower part of the wind selection chamber 10 are unbalanced by the conveyor 19 and dropped into the blow-out pipe 18 via the valve 21 rotated by the motor 20, the wind selection is performed. The air in the chamber 10 can be selected without making it too strong, and the selection is performed well.
