Since some brown rice is contained in the removed scrap rice, conversely, brown rice is taken out from the scrap rice using a sorter. The sorting machine used at this time has a wind tunnel that has a wind turbine provided in a fixed case and blows the wind upward, and a swing frame provided above the wind tunnel,
A sorting net (plate) stretched over the swing frame through which the wind blows upward, an elevator that feeds scrap rice onto the sorting net, and a swing mechanism that swings the sorting net back and forth diagonally up and down. The sorting net has a substantially rectangular shape with one side in the front-rear direction being the supply side, the other side being the discharge side, one side in the left-right direction being the upper side, and the other side being the lower side.

The wind is used to guide the scrap rice to the swaying side. When blown by the wind, light scrap rice emerges, but heavy brown rice does not emerge. The scrapped rice that has floated is lopsided down on the sway, and the heavy brown rice that does not float up is swayed up by the resistance of the sorting plate. Therefore, the wind is important. If it is too strong, it will rise to brown rice, and if it is too weak, it will not be possible to separate scrap rice.

And punched perforated plate 2 in which numerous directional air holes 24 are formed
In the double-layered structure of No. 5, when the air blown up from the air outlet 5 blows through the punched perforated plate 25 and the upper net 23, the air is blown obliquely as shown in FIGS. . The direction of the wind at this time is toward the swaying side 22 and toward the discharge side 20. The upper net 23 is preferably 16 mesh (a net having 16 meshes per inch).

作用はしない。The air blown through the punched perforated plate 25 and the upper net 23 is slightly blown by the wind with respect to the scrap rice b supplied onto the sorting net 18, but the brown rice a is heavy. , It blows to such an extent that it does not rise so much, and since the scrap rice b slightly floats, it does not come into contact with the upper net 23 that swings in the direction of the arrow w below that much, and therefore is not subjected to a swinging force, and the slope It is guided by the wind and flows to the swaying side 22 side, and moves to the discharge side 20 side. Since the brown rice a is heavy, it is not affected by the wind, is strongly shaken in the direction of the arrow w, is swung up by the upside 21, and moves to the discharge side 20. In this case, if only one perforated plate is used as in the known example, the grain will be directly on the perforated plate, and if the air holes are formed with the air holes facing down, the air holes will be formed. Inevitably, the projections that are formed on the side of the punching face are directed toward the swaying side, which has a negative effect on the swaying action of the brown rice.
Since the upper net 23 is superposed on the upper surface 5, the projections formed to form the air holes are hidden by the upper net 23 and have no negative effect.

You can also use something like strip steel. The barrier plate 34 is provided in a direction from the swaying side 21 to the swaying side 22, that is, in the left-right direction, and is fixed by binding with wire, fastening with a small screw, or spot welding. The length of the barrier plate 34 is not full right and left, and both ends are provided with a slight allowance 35 provided. The residual rice is swept from the interval 35. The intermediate rice outlet 29 is returned to the stake 36 of the elevator 31.

Approximately 20% of brown rice is contained, so a mechanism for selecting brown rice from scrap rice is required. The present invention selects brown rice from scrap rice. The operation will be described. When the switch is turned on, the motor 15 is energized, the pulley 7 and the pulley 11 are rotated via the belt 17 to rotate the wind turbine shaft 6 and the drive shaft 8, and the wind turbine 3 fixed to the wind turbine shaft 6 is rotated.
Is rotated to blow wind from the outlet 5, and the swing frame 12 is swung by the eccentric wheel 9 and the rod 10 provided on the drive shaft 8. Since the swing frame 12 is attached to the fixed case 1 by the tilt swing support rods 14, 14, the swing frame 12 tilts and swings in the w direction.

It passes through the lower net 38, flows over the waste rice flow plate 38 below it, and is taken out to the take-out gutter 42. The brown rice a and the waste rice b are the waste rice sorting plate 3
It flows down on 7 and is supplied from the supply port 33 to the swinging side 22 of the sorting net 18 in FIG.

It blows through with directivity, and the scrap rice b receives the wind and rises slightly above the upper net 23, and the brown rice a is heavy and does not rise so much even when it receives the wind. The slightly boiled scrap rice b does not come into contact with the upper net 23 that swings in the direction of the arrow w below that much, and therefore is not subjected to the swinging force of the upper net 23, and is moved to the swinging side 22 side by the gradient and wind. Flowed and discharged by gradient and wind 2
Move to 0. The flow to the swaying side 22 at this time is adjusted by finely adjusting the gradient by the adjusting screw 43.

The movement to the discharge side 20 is delayed because the flow is blocked by the weir plate 34 arranged at a predetermined interval on the upper surface of the sorting net 18, so that it is widely dispersed in the left-right direction,
Selected for a long time.

The scrap rice is taken out to the scrap rice take-out port 30, respectively. The intermediate rice taken out to the intermediate rice outlet 29 is returned to the elevator 31 and circulates. The above-described work is smoothly performed by adjusting the size of the suction port 4 by adjusting the adjusting plate 44 up and down, or by adjusting the rotation speed of the wind turbine 3. Windmill 3
The number of rotations is adjusted by using a continuously variable pulley or a variable speed motor. At the end of work, the sorting net 18
A large amount of grain remains on the top, but it is swept out by utilizing the gap 35.

When blown by the wind, light scrap rice emerges, but heavy brown rice does not emerge. The scrapped rice that has floated is lopsided down on the sway, and the heavy brown rice that does not float up is swayed up by the resistance of the sorting plate. Therefore, the wind is important. If it is too strong, it will rise to brown rice, and if it is too weak, it will not be possible to separate scrap rice. However, according to the present invention, the wind tunnel 2 that has the wind turbine 3 provided in the fixed case 1 and blows the wind upward, the swing frame 12 provided on the upper portion of the wind tunnel 2, and the swing frame 1
A sorting net 18 which is stretched over 2, and through which the wind blows upward;
The sorting net 18 comprises an elevator 31 for feeding scrap rice onto the sorting net 18 and a swinging mechanism for reciprocally swinging the sorting net 18 in a left-right oblique up and down direction. 19 the other side to the discharge side 20 and one side in the left-right direction to the upper side 21
In addition, the other side is a swinging side 22, and the supply side 19 is inclined higher than the discharging side 20 and the swinging side 21 is tilted higher than the swinging side 22, and a partition 26 is provided on the discharge side 20. , 27 are provided to form a brown rice outlet 28 on the rocking side and an intermediate rice outlet 29 on the rocking side in the middle of the scrap rice outlet 30. The windmill 3 adjusts the rotation speed or sucks the wind tunnel 2. Since it is a sorting device for extracting brown rice from the scrap rice whose wind force is variable by adjusting the mouth 4, etc., the wind power of the windmill 3 is adjusted. Since you can adjust to the optimum state while observing the upper state with the naked eye, you can select with the highest efficiency.
