DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sorting cereals and debris.

[0002]

2. Description of the Related Art Conventionally, an air outlet is provided above a wind tunnel surrounding a windmill, a swing frame is disposed above the air outlet, the swing frame is attached by an inclined support rod, and is swung up and down obliquely by an eccentric wheel. It is known that a sorting perforated plate is stretched on an oscillating frame, and the front side of the sorting perforated plate is lowered to provide a grain outlet, and the rear side is raised to serve as a stone waste outlet.

[0003]

Heretofore known ones are:
50-90% of stone debris can be removed, but 10-50%
The disadvantage is that the stone debris remains without being removed. This is because a single sorting perforated plate is intended to separate cereal and debris, and if the debris is to be completely removed, a large amount of cereal will be mixed into the debris. In other words, it is impossible to take out the complete waste.

[0004]

According to the present invention, a wind turbine 1 is surrounded by a wind tunnel 2, an outlet 4 is provided above the wind tunnel 2, and a swing frame 5 is disposed above the outlet 4, Sorted perforated plate 9 for moving frame 5
In the structure in which the main selection part 1 and the sub-selection part 11 are arranged side by side,
The front side of 0 forms a grain take-out port 12 lower than the rear side, and the rear side of the main sorting section 10 forms a traverse section 14 that blows wind in the direction of the sub-sorting section 11. Forms a return portion 15 that blows wind in the front side direction, the front end of the return portion 15 has an opening 16 at the front and rear intermediate position of the sub-selection portion 11, and forms a grain outlet 13 in front of the sub-selection portion 11, At the rear side of the sorting unit 11, a grain and stone sorting device having a stone dust outlet 17 is formed. The debris take-out port 17 is always open, and the edge of the debris is provided with a low weir 18 to provide a device for sorting grains and debris. In addition, a device for sorting cereals and debris having a steep surface 19 near the weir 18 is provided.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
1 is a wind turbine, 2 is a wind tunnel surrounding the wind turbine 1, 3 is a suction opening formed in the wind tunnel 2, 4 is an outlet provided above the wind tunnel 2, 5 is a swing disposed above the outlet 4. Frames 6, 7 are inclined supports mounted between the upper portion of the wind tunnel 2 and the swing frame 5, 8 is an eccentric ring, and 9 is a sorting perforated plate stretched on the swing frame 5.

The perforated sorting plate 9 has a structure in which a main sorting section 10 having a wide width and a sub-sorting section 11 having a narrow width are arranged side by side. Both the main sorting section 10 and the sub-selecting section 11 blow up from the outlet 4. It is a structure that receives wind, and the main sorting unit 10 and the sub-sorting unit 11
Of the front and rear sides, the front side is formed lower and the grain outlets 12 and 13 are formed, the rear side is higher, and the left and right sides are formed horizontally.

[0007] Behind the main sorting section 10, a sub-sorting section 1 is provided.
A traverse unit 14 that blows wind in one direction is formed, and a return unit 15 that blows wind in the front direction is formed at the end of the traverse unit 14. The front end of the return unit 15 is located at an intermediate position in front and rear of the sub-sorting unit 11. Opening 1
6 The grain outlet 13 is formed at the front side of the sub-sorting unit 11, and the stone waste outlet 17 is formed at the rear side of the sub-sorting unit 11. The debris take-out port 17 is always open, and a weir 18 having a height of about 5 mm is provided at the edge thereof, and a steep surface 19 may be formed near the weir 18.

[0008]

Next, the operation will be described. Energize the motor and windmill 1
When the eccentric wheel 8 is rotated, the wind of the windmill 1 is blown from the outlet 4 to the selection perforated plate 9, and the eccentric wheel 8 swings the swing frame 5. When cereals are supplied on the main sorting unit 10 in this state,
Grains are removed from the grain outlet 12 by a well-known sorting theory,
Grains containing debris are deposited on the traversing section 14. Traverse unit 1
Since the grain of the grain deposited on 4 is formed toward the sub-selection unit 11, the grain flows into the return unit 15 by the wind blowing toward the sub-selection unit 11. The eyes of the return portion 15 are formed opposite to the main sorting portion 10 to blow wind toward the grain outlet 12, so that the grains are returned and supplied to the front and rear middle of the sub-sorting portion 11 through the opening 16.

The selection perforated plate of the sub-selection unit 11 is also substantially the main selection unit 1.
0, the grains are taken out from the grain take-out port 13 by the well-known sorting theory, and the grains containing the stones gather toward the masonry take-out port 17. Since a weir 18 is provided in the part, the heavy debris stops there, and the grain does not reach the weir 18 due to the debris. As the operation progresses, the subsequent debris accumulates one after another, only the debris gathers near the weir 18, and finally the first debris is extruded and automatically discharged. The effect of the embodiment of FIG. 6 is even more pronounced because the steep surface 19 is provided.

[0010]

According to the present invention, the wind turbine 1 is surrounded by the wind tunnel 2, the air outlet 4 is provided above the wind turbine 2, and the swing frame 5 is disposed above the air outlet 4, and the swing frame 5 In the structure in which the selection perforated plate 9 is stretched, the selection perforated plate 9 includes a main selection unit 10 and a sub-selection unit 1.
1 is formed side by side, the front side of the main sorting section 10 forms a grain outlet 12 lower than the rear side, and the traverse section that blows wind in the direction of the sub-sorting section 11 behind the main sorting section 10. Form 14,
At the end of the traversing section 14, a return section 15 for blowing wind in the front direction is formed. The front end of the return section 15 has an opening 16 at an intermediate position before and after the sub-sorting section 11, and a grain collecting section is provided at the front side of the sub-selection section 11. Exit 1
3 and a device for sorting grains and debris having a debris take-out port 17 on the rear side of the sub-selection unit 11.
The cereals and debris are separated into grains containing cereals and debris by the main sorting unit 10, and the cereals containing debris are separated from the sub-sorting unit 1.
Since it is separated into grains and swarf by 1, it can be completely separated because it is separated twice. In addition, since the debris take-out port 17 is always open and the edge thereof is provided with a low weir 18 and is a device for separating grain and debris, the main and sub-sorting sections 10 and 11 separate the debris. In the apparatus that separates the grain and the swarf twice, a low height weir 18 is provided at the edge of the normally open swarf take-out port 17, so that the swarf can be automatically discharged. In addition, since the apparatus is a device for sorting cereals and debris in which a steep surface 19 is formed in the vicinity of the weir 18, separation is further improved.
