To form. The left and right sides of the main sorting section 1 are partitioned by the left side wall 5 and the right and left front and rear side walls 6a and 6b, and the rocking side 2 is closed by the rocking side wall 7.

On the bottom surface of the main sorting section 1, a main sorting net 9 is stretched, in which the direction of the blowholes 8 is directed toward the upside 2, and the blowholes are formed on the bottom surface near the upside 2. A horizontal moving net 10 having a rightward direction 8 is stretched, and the right front side wall 6a on the right side of the horizontal moving net 10 is cut out to form a mixed rice inflow port 11. The function of the main sorting net 9 is to separate fine grains and stone scraps. Grains containing stone scraps are accumulated and distributed in the upper part of the lateral moving net 10, and the stone scraps are moved to the right with the grain. The mixed rice is discharged from the mixed rice inflow port 11 to the outside.

Reference numeral 12 is a connecting passage for returning the grains including stone chips that have flowed in from the mixed rice inflow port 11 to the swaying side 3 direction. On the bottom surface of the connecting passage 12, the direction of the blowhole 8 is the swaying side 3. The facing return net 13 is stretched. The return net 13 may have a structure in which wind blows from below or does not blow. The left side of the return net 13 is partitioned by the right front side wall 6a, and the right side of the return net 13 is partitioned by the front side partition wall 14a parallel to the right front side wall 6a. The three rocking-side ends of the front partition wall 14a are cut out to form the outflow port 15, and the sub-sorting unit 16 is formed outside the outflow port 15. The front and rear widths of the sub-sorting unit 16 are the same as those of the main sorting unit 1, and a stone removing port 17 narrowed in a V shape is formed on the upper side 2 of the sub-sorting unit 16. The right side of the sub-selection unit 16 is the outer wall 18
, The swinging side 3 of the sub-sorting unit 16 is surrounded by the rear side wall 19, the left side of the sub-sorting unit 16 is surrounded by the front partition wall 14a and the rear partition wall 14b, and the swinging of the rear partition wall 14b. Open the return port 20 on the side 3 and return it to the upper side 2 of the right rear side wall 6b.
1 to return stones and grains to the main sorting section 1.

Reference numeral 22 designates a sub-sorting net stretched on the bottom surface of the sub-sorting section 16, and the blast holes 8 face the upside 2. 23 is the right rear wall 6
b and the rear partition wall 14b. In the return passage 23, the return passage 23 has the blowout holes 8 in the two upward swing directions.
Install 4 Further, on the swaying side 3 of the sub-sorting section 16, a horizontal moving net 25 having a blowhole 8 facing the direction of the main sorting section 1 is stretched.

[0009]

Operation of the Embodiment Next, the operation will be described. When the main sorting section 1 and the sub sorting section 16 are vigorously rocked in the W direction by one motor and one rocking mechanism and grain is supplied to the central part of the main sorting section 1, the grain has a specific gravity higher than that of stone. Since it is small, it slightly floats up by the wind of the windmill 27, and the stone dust does not float up even if it receives the wind of the windmill 27. Since the floating grain does not come into contact with the main sorting net 9 so much, it is not shaken in the W direction, and flows down due to the gradient of the main sorting unit 1 and is taken out from the grain outlet 4 on the swinging side 3. Since the non-floating debris makes strong contact with the swinging main sorting net 9, it is swung up to the upside 2 side against the gradient. At this time, according to the present invention, not only rocks are rocked up to the rocking side 2 side, but also some grains are rocked up to the rocking side 2 side. Only fine grains without debris.

The mixture of grains and stones swung to the upper side 2 of the rocking side is blown toward the mixed rice inflow port 11 by the wind from the blowholes 8 of the lateral moving net 10, and the communication path from the mixed rice inflow port 11 Flows into 12. The blast holes 8 of the return net 13 of the communication passage 12 are directed to the swaying side 3, so that they are transferred in the swaying side 3 direction by rocking and flow out from the outlet 15 to the sub-sorting unit 16.
In the sub-sorting section 16, since the blast holes 8 face toward the stone removing port 17 on the rocking side 2, the same action as that of the main sorting net 9 is achieved.
The stone moves in the direction of the stone removing port 17, but at this time, since some of the stones and grains form the eyes of the blowholes 8 so as to move to the rocking side 3, The grain moves to the rocking side 3 and only the stone moves to the rocking side 2.

A part of the stone and grain mixture that has moved to the swaying side 3 moves into the return passage 23 by the lateral moving net 25,
It is returned to the main selection unit 1 from the return outlet 21 and recirculated.

[0012]

Since the conventionally known stone removing device has a limited capacity, a large number of rice mills are arranged in parallel for parallel processing. In the case of a large-scale rice milling plant, a plurality of conventionally known stone removing devices are provided in parallel, so that the cost is considerably high. Then, the cost of the stone removing device is incurred by the windmill part provided below the sorting plate, and the sorting plate is
Since it is produced by a sorting board manufacturing specialist, it is relatively inexpensive. However, according to the present invention, one side of the main sorting unit 1 having a substantially rectangular shape in plan view is shaken upside 2 and the other side is shaken down 3 and the rocking upside 2 is tilted higher than the shake down side 3 to cause the shake down. On the side 3 side, a grain extraction port 4 is formed over the entire width, and on the bottom surface of the main sorting section 1, a main sorting net 9 in which the direction of the eyes of the blast holes 8 is directed toward the upper side 2 is stretched. And the direction of the eyes of the blast holes 8 swings to the side of the main selection unit 1 with the same gradient as the main selection unit 1
Sub-selection unit 1 in which a sub-selection net 22 facing in the direction of
6 are integrally formed, and the main sorting section 1 and the sub sorting section 1 are formed.
A communication passage 12 extending from the upper side 2 of the main sorting unit 1 to the front-rear center of the sub sorting unit 16 is integrally provided between 6 and
The stone removing port 17 is formed on the upper side 2 of the sub-sorting unit 16,
A return passage 23 is formed between the sub-sorting unit 16 and the main sorting unit 1 from the swaying side 3 of the sub-sorting unit 16 to the center of the main sorting unit 1 in the front-rear direction. A windmill 27 is provided below the sub-sorting unit 16 to provide a stone removing device for removing debris mixed in the grain. Therefore, the main sorting unit 1 mixes the grain and the mixture of grain and stone. Since it is divided into stones and a mixture of grains and stones by the sub-sorting unit 16, efficient separation is possible. Further, since one wind turbine 27 is provided below the main sorting unit 1 and the sub sorting unit 16, the cost can be reduced.
