DISCLOSURE OF INVENTION Problems to be Solved by the Invention
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 scrap rice that has surfaced can be made to drift to the swaying side with a gradient. However, the wind is not enough to float the scrap rice, so we want to give direction to the wind and guide the scrap rice to the swaying side by the force of the wind. However, the known example cannot do that. In order to guide scraped rice to the swaying side by the force of the directional wind, the direction of the air hole must be formed so that the swaying side is facing, but such a wind hole is inevitable. It becomes a downward-facing projection and negatively affects the drift of brown rice to the upside. Also, as mentioned above,
The heavy brown rice that drifts downward on the gradient and is swung up against the gradient due to the resistance of the sorting net, the gradient must be adjusted to do so.

[0004]

Therefore, according to the present invention, the wind tunnel 2 having the wind turbine 3 provided in the fixed case 1 for blowing the wind upward, and the swing frame 12 provided at the upper portion of the wind tunnel 2 are provided. And a sorting net 18 stretched over the swing frame 12 through which the wind blows upward.
And a lifting mechanism 31 for supplying scrap rice onto the sorting net 18 and a swinging mechanism for reciprocally swinging the sorting net 18 in a diagonally right and left vertical direction. The sorting net 18 has one side in the front-back direction. The supply side 19 has the other side, the discharge side 20 has a substantially rectangular shape with one side in the left-right direction swinging up 21, and the other side swinging down 22, and the supply side 19 is higher than the discharge side 20 and the swinging side 21 is higher. Is inclined higher than the swaying side 22, and partitions 26 and 27 are provided on the discharging side 20 to provide a brown rice outlet 28 on the swaying side and a scrap rice outlet 30 on the swaying side and an intermediate rice outlet 29. The sorting net 18 was formed by adhering and superimposing the upper net 23 on the punched perforated plate 25 in which numerous directional air holes 24 were formed.
The sorting net 18 has a double structure, and the sorting net 18 is provided with a left and right inclination adjusting mechanism to serve as a sorting device for picking brown rice from the scrap rice.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a peripheral fixed case. A wind tunnel 2 that blows upward is fixedly provided at a lower position in the fixed case 1, and a wind turbine 3 is axially mounted in the wind tunnel 2. 4 is a suction port, 5 is a blowout port, 6 is a wind turbine shaft that is substantially horizontal in the front-rear direction, and 7 is a pulley attached to the end of the wind turbine shaft 6. A drive shaft 8 parallel to the wind turbine shaft 6 is provided above the wind tunnel 2, and eccentric wheels 9 are provided on the front and rear sides of the drive shaft 8.
9 is attached, and the bases of rods 10 are axially mounted on the eccentric wheels 9. Reference numeral 11 is a pulley fixed to the end of the drive shaft 8.

A wind tunnel / rocking frame 12 is attached to the upper part of the wind tunnel 2, and shafts 13 and 13 provided on the lower part of the rocking frame 12 are
The tips of the rods 10 and 10 are axially attached. The swing frame 1
At a position above the two shafts 13 and 13, the tilt swing support rod 1 is provided.
The lower portions of 4 and 14 are pivotally attached, and the upper ends of the tilting swing support rods 14 and 14 are pivotally attached to the fixed case 1 side. 15 is a motor, 16
Is a drive pulley, the drive pulley 16 and the pulley 1
A belt 17 is wound around 1 and the pulley 7.

Therefore, when the motor 15 is energized, the wind turbine 3 rotates and the wind tunnel and swing frame 12 has a swing of about 11 mm per minute.
Swing about 350 to 400 times. The known rocking sorter for selecting brown rice and unhulled rice has a swing width of about 45 mm and a swing width of about 220 to 300 times per minute, so that the swing width is about 1/4. It is small and the frequency is about 1.8 times higher.

A sorting net 18 is stretched above the wind tunnel and swing frame 12. The sorting net 18 has a substantially square shape as shown in FIG. 4, one side in the front-rear direction is a supply side 19, the other side is a discharge side 20, one side on the left and right sides is an upper side 21, and the other side is a lower side 22. Discharge side 2
The supply side 19 side is slightly higher than 0, the swing side 21 is higher than the swing side 22, and they are inclined in both directions.

The sorting net 18 is an upper net 23 made of a woven net.
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).

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.

The discharge side 20 is provided with partition plates 26 and 27 which are adjustable in the left-right direction at intervals in the left-right direction.
6 is formed as a brown rice outlet 28, a portion between the partition plate 26 and the partition plate 27 is formed as an intermediate rice outlet 29, and a portion 22 below the partition plate 27 is formed as a scrap rice outlet 30. When the direction of the drive shaft 8 is set to the front-back direction, the rocking upper side 21 on the left and right sides
An elevator 31 is provided on the side of the elevator 31, and a vertical line / supply gutter 32 is provided below the upper discharge gutter of the elevator 31.

A vertical wire is a device for separating scrap rice by pouring a metal wire in the vertical direction with a gap of about 1.70 mm or 1.75 mm, and pouring rice on it to separate scrap rice. Has stretched piano wires with a front and rear spacing so that the spacing can be adjusted freely.However, some of the less expensive ones have punched slits in a thin iron plate, and those skilled in the art collectively refer to them as vertical lines. There is.
The scrap rice is once sorted by a vertical line, but in the present application, a vertical line with a slit width smaller than that is used for the elevator 31.
Installed in the lower part of the discharge gutter.

Since the supply gutter 32 is attached in the left-right direction and is integrally fixed to the upper part of the swing frame 12, it swings together with the swing frame 12, and therefore is of a swing type.
The tip of the supply gutter 32 is opened laterally to form a supply port 33, and the position of the supply port 33 is on the swinging side 22 as shown in FIG.

Barrier plates 34 are arranged on the upper surface of the screening net 18 at a predetermined interval. The barrier plate 34 is for spreading the grains as much as possible so as to prevent them from flowing, and is like a rail of fittings, like L-shaped steel,
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.

The supply gutter 32 has a triple structure of a waste rice sorting plate 37, a lower net 38 and a waste rice flow plate 39, and a clogging removal ball 40 is housed between the waste rice sorting plate 37 and the lower net 38. , And collide with the partition bar 41 having a triangular cross section to slide it. The scrap rice that has flowed through the scrap rice flow plate 39 is taken out to the take-out gutter 42.

Reference numeral 43 is a screw for adjusting the right and left inclination of the sorting net 18, and in this case, as shown in FIG.
2 is divided into upper and lower parts, and a screw 43 is attached between them.

[0017]

[Operation] Next, the operation will be described. The brown rice that has been hulled by the hulling device is removed as the finished rice by the rotary scrap rice sorting device, and is distributed to the market as finished rice. However, in the scrap rice that was removed,
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.

In this state, when the scrap rice is supplied from the inlet 36, it is lifted by the elevator 31 and flows down on the scrap rice sorting plate 37 in the supply gutter 32, and the very small scrap rice c is separated. 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.

As shown in FIG. 3, the screening net 18 is a stack of two perforated punched plates 25 and an upper net 23 having directivity, so that the wind blows through has a directivity toward the swaying side 22 and the discharging side 20. Since it has blown through, the scrap rice b receives the wind and floats slightly above the upper net 23, and the brown rice a does not float so much even when it receives the wind because it is heavy. The slightly floated waste 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 thus the upper net 2
It does not receive the swaying force of 3 and swings down 22 due to the gradient and wind.
Side to side and move to the discharge side 20 due to the gradient and wind. The flow to the swaying side 22 at this time is the adjustment screw 43.
Adjusts the gradient delicately by adjusting.

On the other hand, since the brown rice a is heavy and does not float so much even if it is exposed to the wind, it is strongly shaken in the direction of the arrow w to be swung up to the upside 21 and moved to the discharge side 20.
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.

Since the discharge side 20 is provided with partition plates 26, 27 which can be adjusted in the left-right direction with a space in the left-right direction, brown rice can be removed by adjusting the positions of the partition plates 26, 27. 28, middle rice at middle rice outlet 29,
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.

At the end of the work, a large amount of grain remains on the sorting net 18, but it is swept out using the gap 35.

[0023]

EFFECTS OF THE INVENTION The known selection plate uses wind for guiding the scrap rice to the swaying side. When blown by the wind, light scrap rice emerges, but heavy brown rice does not emerge. The scrap rice that has surfaced can be made to drift to the swaying side with a gradient. However, because the wind is not enough to float the scrap rice,
We want to give direction to the wind and guide the scrap rice to the sway side by the force of the wind. However, the known example cannot do that. In order to guide scraped rice to the swaying side by the force of the directional wind, the direction of the air hole must be formed so that the swaying side is facing, but such a wind hole is inevitable. It becomes a downward-facing projection and negatively affects the drift of brown rice to the upside. In addition, as mentioned above, the surplus waste rice drifts downward on the slope and the heavy brown rice is swung upward against the slope due to the resistance of the sorting net. The slope must be adjusted. However, according to the present invention, the wind tunnel 2 having the wind turbine 3 provided in the fixed case 1 for blowing the wind upward, the swing frame 12 provided at the upper portion of the wind tunnel 2, and the swing frame 12 are stretched. The sorting net 18 through which the wind is blown upward
And a lifting mechanism 31 for supplying scrap rice onto the sorting net 18 and a swinging mechanism for reciprocally swinging the sorting net 18 in a diagonally right and left vertical direction. The sorting net 18 has one side in the front-back direction. The supply side 19 has the other side, the discharge side 20 has a substantially rectangular shape with one side in the left-right direction swinging up 21, and the other side swinging down 22, and the supply side 19 is higher than the discharge side 20 and the swinging side 21 is higher. Is inclined higher than the swaying side 22, and partitions 26 and 27 are provided on the discharging side 20 to provide a brown rice outlet 28 on the swaying side and a scrap rice outlet 30 on the swaying side and an intermediate rice outlet 29. The sorting net 18 was formed by adhering and superimposing the upper net 23 on the punched perforated plate 25 in which numerous directional air holes 24 were formed.
Since the sorting net 18 has a double structure, and the sorting net 18 is provided with a horizontal inclination adjusting mechanism to remove brown rice from the scrap rice, the upper net 2 is placed on the punched perforated plate 25 having the air holes 24.
Since it has a double structure in which 3 is polymerized, the projections formed when the air holes 24 are formed can be hidden by the upper net 23, and only wind can be applied to the scrap rice for good selection. Moreover, since the gradient in the left-right direction can be adjusted, accurate separation can be achieved.

[Operation] Next, the operation will be described. The brown rice that has been hulled by the hulling device is removed as the finished rice by the rotary scrap rice sorting device, and is distributed to the market as finished rice. However, in the scrap rice that was removed,
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.

In this state, when scrap rice is supplied from the inlet 36, it is fried by the elevator 31 and flows down on the scrap rice sorting plate 37 in the supply trough 32, and the extremely small scrap rice c is separated. 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.

As shown in FIG. 3, the sorting net 18 is a stack of two punched perforated plates 25 and an upper net 23 having directivity, so that the wind blows through has a directivity toward the swaying side 22 and the discharging side 20. Since it has blown through, the scrap rice b receives the wind and floats slightly above the upper net 23, and the brown rice a does not float so much even when it receives the wind because it is heavy. The slightly floated waste 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 thus the upper net 2
It does not receive the swaying force of 3 and swings down 22 due to the gradient and wind.
Side to side and move to the discharge side 20 due to the gradient and wind. The flow to the swaying side 22 at this time is the adjustment screw 43.
Adjusts the gradient delicately by adjusting.

On the other hand, since the brown rice a is heavy and does not float so much even if it is exposed to the wind, it is strongly shaken in the direction of the arrow w to be swung up by the upside 21 and moved toward the discharge side 20.
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.

Since the discharge side 20 is provided with partition bodies 26, 27 which are adjustable in the left-right direction at a left-right direction, brown rice can be removed by adjusting the positions of the partition bodies 26, 27. 28, middle rice at middle rice outlet 29,
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.

At the end of the work, a large amount of grain remains on the sorting net 18, but it is swept out using the gap 35.

EFFECTS OF THE INVENTION The known selection plate uses wind for guiding the scrap rice to the swaying side. When blown by the wind, light scrap rice emerges, but heavy brown rice does not emerge. The scrap rice that has surfaced can be made to drift to the swaying side with a gradient. However, the scrap rice is efficiently deflected to the sway side on the slope.
In order to do this, the gradient should be adjustable . Also, directionality
If you try to guide the scrap rice to the swaying side by the force of a certain wind,
A more remarkable effect can be expected, but with such directivity
The air vents are protrusions that face the swaying side, to the upside of the brown rice.
This also improves because it has a negative effect on the drift of
