Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oscillating grain sorting method and an apparatus therefor.

In other words, the first defect in the known example is that the grains are separated by performing a reciprocating motion diagonally upward F, and the second defect is that the mixed grains with a width of ml are returned using a circulating device. Bitten.

This is because the actual size of the sorting board is at least 1 m'
(length: 1 m x width: 1 m), and at least 5 stages are stacked (unless they are formed in 5 stages, it will not match the hulling efficiency of the hulling device), and in the end, very heavy items are shaken diagonally up and down. Since the structure was such that it would be destroyed and disposed of, something that could withstand this was required.

Further, it is very troublesome to discharge the mixed grains and return them to their original state.

The present invention overcomes each of the above two deficiencies in separate ways.

In other words, FIG. 1 shows a typical known example, in which numeral 1 is a sorting plate, and numerous projections 2 are formed on the surface of the sorting plate 1.

This sorting plate 1 is attached to an underframe 4. 5.6 is a diagonal rod, and the lower end of the diagonal rod 5.6 is attached to the underframe 4'' as an axis.
8, and the sorting plate 1 is pivoted to the -L end of the diagonal rod 5.6.
It will be 0. 11 is an eccentric wheel, and 12 is a rod. When the eccentric wheel 11 rotates, the sorting plate 1 is reciprocated in the direction of the arrow through the rod 12. The sorting plate 1 has a rectangular ridge shape, with a supply side 13 on one left and right side and a discharge side 14 on the other side, and the supply side 13 is formed higher than the discharge side 14 and is inclined. Also, the rear side of Iiu is the rocking side 15.
, the front side becomes the swinging side 16, and the force of the swinging side 15 becomes the swinging side 1.
It is tilted at an α angle lower than 6.

Further, 17 is a supply funnel, and the discharge side 14 is opened by force to the full width, and a paddy/rice outlet 18 is provided on the swing side 15 of the four-way outlet side 14. − side 16
A brown rice outlet 19 is provided in the middle, and a mixed grain outlet 20 is provided in the middle.
has been established. In this known example, unhulled rice is fed from the feed funnel 17.
When the mixed grains of brown rice are supplied to the sorting plate 1-1 and the eccentric wheel 11 is rotated, the sorting plate 1 swings in the direction of the arrow, and the four grains on the sorting plate 1-1 are swung. let Therefore, as a secondary sorting phenomenon, brown rice with a heavy specific gravity sinks to the lower layer and is stirred up to the shaking side 16, and as a secondary phenomenon, it drifts on the shaking side 16 as shown by El in Fig. It is taken out. Paddy rice a with a light specific gravity is brown rice b-1 that has settled to the lower layer:
After floating to the surface, it drifts to the shaking side 15 like E2 and is taken out to the paddy rice outlet 18, and in the middle there are 4 grains that are not separated like E3! 1j Remove mixed grains 1"20
It is taken out.

As explained above, in the known example, the movement is diagonal up and down in the direction of the arrow (B), and the 4-piece grains are distributed as shown in E3 and taken out to the mixed grain outlet 20. There was a flaw.

Therefore, in the present invention, a sorting plate with unevenness formed on the plate surface is swung approximately horizontally in the front and rear directions to separate the mixed rice of different types fed onto the plate surface in the front and rear directions, and the separated grains are separated on the left and right sides. (Required) A rocking type grain sorting device in which grains are taken out in one or both directions, wherein the sorting plate swings back and forth at a rate of at most 1:1.2 or less, and
111 of the sorting plate 21 has a rectangular shape.
A raised wall 24 is formed on the edge of the separation plate 21 over the entire width, and a raised wall 25 is similarly formed on the rear edge of the farewell plate 21 over the entire width. In this case, a group of left inclined protrusions 26 whose tips are oriented toward the left on the left of the left and right sides are formed on the entire plate surface, and on the rear plate surface of the sorting plate 21, a group of 26 left inclined protrusions are formed on the plate surface on the rear side of the sorting plate 21. A group of right inclined protrusions 27 facing rightward is formed over the entire board surface, and both the left inclined protrusions 26 and the right inclined protrusions 27 are formed in a direction to draw the grain toward the W upper wall 24 of the leading edge. A brown rice outlet 28 is formed in the front part of one side of the sorting plate 21, and the other part is closed by a wall, and an unhulled rice outlet 30 is formed in the rear part of the other side of the sorting plate 21, and the other part is closed by a wall. is a wall, and the sorting plate 21 is configured to be a oscillating grain sorting device in which the sorting plate 21 is oscillated back and forth within 1:1.2 at most. An example of this will be explained with reference to the drawings.
is a sorting plate of the present invention, and the sorting plate 21 of the embodiment has a front and back width of 2
The left and right width 23 is longer than that of 2 (FIG. 7), and the elevation shape is a rectangular shape.

A rising wall 24 is formed over the entire width at the front edge of the sorting plate 21, and a rising wall 25 is similarly formed over the entire width at the rear edge of the one sorting plate 21. Therefore, on the front plate surface of the sorting plate 21, a group of left inclined protrusions 26 whose tips are directed toward the left if it is the left side of the left or right side is formed over the entire plate surface, and the sorting plate 21
On the rear plate surface I-, a group of right-slanted protrusions 27 facing rightward on the right side of the left and right sides is formed over the entire plate surface. As is clear from the cross-sectional view of FIG. 9, the left inclined projection 26 and the right inclined projection 27 are both formed in a direction to draw the grain toward the front edge vertical 1-wall 24 direction.

A brown rice outlet 28 is formed in the left front part of the sorting plate 21, and the rest is closed off by a left wall 29. A paddy/rice outlet 30 is formed in the right rear portion of the sorting plate 21, and 32, which is otherwise closed by the right wall 31, is a supply hopper. Sorting board 2
1 is attached to the upper end of the support rod 34.34 which is pivoted to the support stand 33.
Arrived at klI. 35 is an eccentric wheel, and 36 is a rod. The angle θ between the rod 36 and the support rod 34 is smaller than a right angle, and a quick return structure is formed. FIG. 5 is a perspective view of the rod 36, which shows that the rod 36 has a shape that is wider toward the top.

Numeral 37 is a screw rod that adjusts the inclination angle of the sorting plate 21 in the front and back direction.The screw rod 37 is formed to swing in opposite directions to the left and right, and the pieces 38 and 38 are screwed into the screw rod 42, respectively, and the arm 39 is attached to the pieces 38 and 38. The two ends are pivoted, the lower end of the arm 39 is pivoted to a boss 41 provided on the L-shaped moving rod 40, and the lower end of the rear support lever 34 is pivoted to the lower moving lever 40.

Next, we will discuss the effect.

In the present invention, with the above configuration, when the eccentric wheel 35 is rotated, the angle θ between the rod 36 and the support rod 34 is smaller than the right angle, so the eccentric/zero wheel 35 changes from A to B to C in FIG. When rotated, at point A, the support rod 34 is tilted to the left to the maximum, but at point C, the support rod 34 is tilted to the maximum to the right. Then, Ha → Two → I.

When it rotates, it returns to its original state, but in this case, the relationship is Iha → Kuha → A, so A → Ha moves faster, resulting in a faster return, and when the sorting plate 21 moves from the front side to the rear side, It moves horizontally quickly, and moves horizontally slowly when moving from the rear to the front.

Therefore, the mixed grains of unhulled rice a and brown rice were supplied to
When the grains of unhulled rice A and brown rice are fed to the sorting plate 21 from 2, they are initially in a completely mixed grain state as shown in FIG. As a result, the brown rice sac with a heavy specific gravity sinks to the lower layer, and the unhulled rice a, which has a lighter specific gravity, floats to the upper layer of the brown rice group, and only the brown rice sump that has sunk to the lowest layer comes into contact with the left inclined protrusion 26 and the right inclined protrusion 27.

In this way, the bottom layer of brown rice that has come into contact with the left inclined protrusion 26 and the right inclined protrusion 27 is affected by the inclined protrusions 26 and 27, and as a secondary phenomenon, the front edge of the sorting plate 21 gradually rises. '' moves toward the second wall 24 and is deposited relatively thickly on the front half of the sorting plate 21. On the contrary, the rear half of the sorting plate 21 is deposited relatively thinly. In this case, the forward movement speed of the grain 3 is determined by rotating the screw rod 37. In other words, screw rod 37
When rotated, due to the action of the opposite thread grooves 42 and 42,
The pieces 38, 38 move toward or away from each other, thereby changing the support rods 34, 34 from an oblique position to a vertical position, causing the vertical movement rod 40 to move up and down. Then, the front and rear inclination angles of the sorting plate 21 are adjusted, and as shown in FIG.
On the other hand, the second half of the second sorting board becomes relatively thinner. In this way, the brown rice sludge is deposited relatively thickly on the front half of the sorting plate 21, and the unhulled rice a that floats to the surface of the brown rice sluice slides on the inclined surface of the brown rice sludge and slides on the rear half of the sorting plate 21. move towards. As a tertiary phenomenon, the brown rice begins to move to the left along the front rising wall 24 due to the action of the tip of the left inclined projection 26, and is taken out to the brown rice outlet 28. The grain a slides on the upper layer of brown rice on the inclined surface and accumulates on the rear half of the sorting plate 21, but on the rear half of the sorting plate 21, as a quaternary phenomenon, the right inclined protrusion 27
is transferred to the right side of the sorting plate 21. However, due to the action of the right inclined protrusion 27, the sorting plate 21
Since the secondary phenomenon is still being sorted out, the purity of the unhulled rice a gradually increases as it advances toward the unhulled rice outlet 30, and finally it becomes complete unhulled rice and is removed from the unhulled rice outlet 30. While being taken out, the mixed grains are deposited in the center of the sorting plate 21 and swirl around, and the newly supplied brown rice and unhulled rice a are only metabolized and never leave the sorting plate 21.

As mentioned above, the known example has the S- defect in that it performs reciprocating motion at an angle J:r for sorting.
The second defect is seen in the fact that mixed grains with a width of ml are returned to the circulation device.

This is because the actual size of the sorting board is at least 1 m'
(1m in length and 1m in width), and at least 5 stages are stacked (unless they are formed in 5 stages, it will not match the hulling efficiency of the hulling device), and in the end, a very heavy item was created. The structure was such that it was shaken and sorted, so something that could withstand that process was required.

Further, it is very troublesome to discharge the mixed grains and return them to their original state.

However, in the present invention, a sorting plate with irregularities formed on the plate surface is swung approximately horizontally in the front and rear directions, and the mixed rice of different types supplied on the plate surface is separated in the front and rear directions, and the separated grains are separated on the left and right sides. The grain sorting method is such that the sorting plate is oscillated back and forth at a rate of at most 1:1.2 or less, and the elongated shape is elongated. Standing on the front edge of the sorting plate 21 which has a rectangular shape
A wall 24 is formed over the entire width, and a rising wall 25 is similarly formed over the entire width at the rear edge of the sorting plate 21.
On the front plate surface of the board, a group of left inclined protrusions 26 whose tips are directed toward the left if it is the left side of the left or right sides are formed over the entire plate surface;
On the rear side of the sorting plate 21, a group of right-slanted protrusions 27 are formed over the entire plate surface, and the right-slanted protrusions 27 are oriented toward the right. , in both cases, the grains are formed in a direction toward the rising wall 24 of the leading edge,
A brown rice outlet 28 is formed in the front part of one side of the sorting plate 21, and the other part is closed by a wall, and a paddy rice outlet 30 is formed in the rear part of the other side of the sorting plate 21, and the other part is closed with a wall. is the wall,
Since the sorting plate 21 is a swing type grain sorting device in which the sorting plate 21 swings back and forth as quickly as 1 to 1.2, the above-mentioned defects can be overcome.
