Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swing-type sorting device for unhulled rice and brown rice.

The present invention was developed in order to obtain a device for sorting unhulled rice and brown rice that is easy to handle and has better sorting performance than conventional sorting devices.

The points in which the present invention differs from conventionally known ones are as follows.

The sorting devices shown in FIGS. 1 to 5 are representative examples of conventionally known devices.

FIG. 1 is an enlarged view of a sorting plate A of a known sorting device and brown rice on the sorting plate A. As shown in FIG. 1, when brown rice B is placed on a sorting plate A and the sorting plate A is agitated back and forth in the direction of the arrow W, the brown rice B is agitated by the agitation and gradually moves in the direction of the arrow C. This is because the surface of the sorting plate A is uniquely formed with countless irregularities. This unevenness is generally called a rough surface or a fluid friction surface.

Therefore, a sorting plate A is formed as shown in the cross-sectional view of FIG. 2 and the front view of FIG. G (black powder)
When a large amount of mixed grains with and are fed onto the sorting plate A, and the sorting plate A is moved back and forth in the direction of the arrow W several times as described above,
Due to the slight difference in specific gravity between them, the brown rice grain group B gathers on the side wall E on the up-shaking side, and on the opposite side, on the down-shaking side l! Group 0 of unhulled rice gathers on the F side, and the two separate from each other.

In Figure 2, the range indicated as m is where only brown rice B is distributed, the range indicated as m is where unhulled rice G and brown rice B are mixed to some extent, and Naruto, which is shown as a town, is where only unhulled rice G is distributed. Where m is distributed, m is a blank space that occurs due to the incitement relationship.

An example of a known sorting device equipped with the sorting plate A shown in FIG. 2 is shown in FIG. 3, where H is a supply hopper, ■ is an underframe, and the sorting plate A is a It is pivotally supported by a supporting rod JJ that is inclined with respect to I, and is agitated in the W direction by an eccentric wheel K. L is brown rice outlet, M is mixed rice outlet,
N is the outlet for taking out unhulled rice.

The known example shown in FIGS. 4 and 5 is an improved example in which the blank portion WL3 on the swinging side formed on the sorting plate A is not generated, and the side wall E on the swinging side of the sorting plate A If the side is lifted as shown by the arrow and tilted α, if the angle is appropriate, the blank portion m3 will be completely eliminated and the sorting effect will be improved. FIG. 5 is a front view of the sorting plate A when it is tilted by α, and all the ones generally available on the market are similar to the known example shown in FIG.

However, since there are some dissatisfaction with the sorting device shown in FIG. 5, and the present invention is an improvement on this, it is necessary to point out the defects of the known example shown in FIG.

That is, the known example shown in FIG. 5 has an original defect in that it performs diagonal up and down reciprocation in the direction of arrow W. This is because the actual size of the sorting plate A shown in the diagram is at least 1 m' (1 m wide x 1 m long).
(m) exists, and Figure 5 only shows the principle of the invention, so if it is not sorted, it will not match the hulling efficiency of the hulling device), and in the end, very heavy items are sorted by shaking them diagonally up and down. It had this structure. Moreover, as clearly shown in Figure 4, the grains are densely distributed on the sorting plate A, and the total weight of the distributed grains is at least 30
(Selecting device) +
(30 tons of distributed grain) was moved diagonally up and down using an eccentric wheel.

Therefore, the underframe (2) had to be able to withstand this, and the structure and strength of each part had to be able to withstand this as well.

Furthermore, the entire factory had to be constructed to withstand this, so a surprisingly thick concrete floor was formed, on which the sorting equipment of the known example shown in Figure 5 was installed. Of course, although the underframe I in FIG. 5 only illustrates the principle of the invention and is very simply illustrated, in reality,
Rather than a simple underframe, in some cases the case of a rice hulling device was used instead of a simple underframe.

Therefore, the strength of the case was required to be surprisingly strong.

The present invention overcomes the deficiencies pointed out above, and provides a sorting device that is easy to handle and has excellent performance.

The present invention Countless irregularities are formed on the surface of the a0 sorting plate.

The profile of the b0 sorting plate is approximately square, with one front and back side being a supply side, the other side being a discharge side, one left and right side being a rocking side, and the other side being a non-rocking side.

The C0 sorting plate is inclined with a discharge flow angle in the front-back direction.

There is a side wall standing approximately at right angles on the supply side/swinging side e non-swinging side of the d0 sorting plate.

The C0 sorting plate is equipped with a left-right reciprocating device that moves faster when moving toward the non-rocking side than when moving toward the rocking side.

This is the gist of the report.

To explain an embodiment of the present invention, (1) is a sorting plate. The original plate (1) is made of a thin metal plate, synthetic resin, or the like. The concave shape of the original plate (!) is formed into a substantially square shape. Preferred embodiments are square or rectangular.
It is. As shown in the plan view of FIG. 8, the original plate (1) is
One side of the front and rear sides is the supply side (2), and the other side is the discharge side (3)
One of the left and right sides is the rocking side (5), the other side is the non-cracking side (6), and the discharge side (3) is not attached to take out the grain, but it is connected to the supply side (2) and the rocking side. The swing side (5) and the non-swing side (
6) is provided with an upwardly projecting side wall (4) to prevent grain from spilling outside. FIG. 12 shows a longitudinal section of a part of the original plate (1). Fig. 12 is made of a metal plate, and the unevenness (7) is formed by press working.

The original plate +11 is made of iron plate, aluminum, synthetic resin, etc., and each has its advantages and disadvantages. As shown in FIG. 6, a supply hopper (8) is provided at an upper position on the supply side (2) of the sorting plate (1). The hopper (8) is located on the rocking side (
5). Although the single-stage chisel (11) in the embodiment diagram is not shown, it is free to form it into a multi-stage type. A multi-stage sorting plate (a distributing device for evenly distributing the liquid is installed between each stage.The sorting plate (1) is lower on the discharge side (3) and has a discharge flow angle β. (No. 101J) This angle β is not an angle at which grains will naturally roll and be discharged;
This is the angle at which the liquid is discharged while maintaining its layered form in relation to the reciprocating movement in the left and right direction. The angle β is adjustable. The easiest way to adjust the angle β is to tilt the entire table (equipment), but it is sufficient to cut off only the sorting plate ill, pivot one end, and attach a screw to the other end.

The sorting plate (1) may be attached with its left and right sides inclined at an α angle as shown in FIG. 19, and the purpose is the same as that in FIG. 4.

However, below the sorting plate 0), an underframe (9) is provided with a vertical interval. Bearings (10fiI) are provided on the left and right sides of the underframe (9) (Fig. 189),
Each lower end of the support rod α2Q3 is pivotally supported by the bearing QIQυ. Further, bearings α4α9 are provided on the lower surface of the sorting plate fl+, and the upper ends of the support rods tier 03 are respectively supported. As is clear from FIG. 9 and FIG.
9) and sorting plate +11 have a total of 4 supports (13aa (1
3 (It will be supported by 13.

However, one end of the rod αη is fixed to the longitudinal shaft αe which pivotally supports the bearing I and the upper end of the support rod a, and the rod a
The other end of η is fixed to the tip of the crank QII. The crank side is fixed to the driving shaft α (σ), and a pulley (■) is fixed to the driving shaft a9 (Fig. 1O). in this case,
The relationship between the position of the driving shaft α9 and the rod (Iη, etc.) is such that when the sorting plate (1) moves toward the non-swinging side (6), it quickly moves, and when the sorting plate +11 moves toward the swinging side (5), it moves quickly. When moving, use a so-called quick return mechanism that moves slowly.
One-.

The quick-return mechanism of the middle rod shell performs work only during reciprocation and does not perform work during backward movement, so it is used to return the rod as quickly as possible and have it perform work again. The concept of total heat is different, and the forward movement is made faster to move the entire grain, and the backward movement is made slower to return only the surface grains to slide.10 In the figure, Q9 is the paddy rice removal port; Q? j is brown rice outlet, (c)
is the mixed rice outlet.

Next, we will discuss the effect.

When the mixed rice of unhulled rice G and brown rice B is dropped from the supply hopper (8) and fed to the supply side (2) of the sorting plate (11), and the motor rotates the pulley ■, the driving shaft α is rotated, and as shown in FIG. As shown in the diagram, the driving shaft rotates to the left in an E-low-harney-A direction.Then, the crank whose base is fixed to the driving shaft 01 (when the I ladder is in the A position, the rod α
When D is at the maximum extended position and the crank 0 mark rotates to the position where the mouth is, the support rod O2 becomes vertical, and when it rotates further and reaches the position C, the support rod 02 is tilted to the right to the maximum.

Then, when returning to position A after passing through position 2, the supporting rod z returns to its original position, but in this case, the rotation angle of Iha, which is a backward movement, is smaller than the rotation angle of Hi, which is a forward movement. Therefore, as the support rod α1m moves, the sorting plate (1)
When moving toward the rocking side (5), it moves slowly, but when moving toward the non-rocking side (6), it moves quickly, so it moves as shown in Figures 13 to 18. Then, unhulled rice Q and brown rice B are separated. That is, the state immediately after being supplied from the supply hopper (8) is as shown in Fig. 13, but when the sorting plate (1) suddenly moves to the right due to the forward movement of the feeder shown in Fig. 11, the impulse Accordingly, the whole mixed rice is the 14th
It is shifted to the left side as shown in the figure. At this time, in just one movement, the top and bottom of brown rice B and unhulled rice G are not completely separated, but little by little, brown rice B, which has a heavier specific gravity, is separated.
will sink to the lower layer, and unhulled rice G, which has a lighter specific gravity, will float to the upper layer.

Then, the sorting plate (1) in the state shown in Figure 14 slowly moves back while the crank a hammer rotates from 8 to A, and becomes as shown in Figure 15, but when the sorting plate +1+ moves slowly. The grains in the lower layer on the sorting plate (11) move as they are, and only the grains in the upper layer slide along the slope and move as indicated by the dotted arrows. Therefore, when comparing Figures 13 and 15, it is found that However, in Fig. 15, the unhulled rice G is distributed on the right side.If you repeat this fast return and reciprocating motion many times, it will become as shown in Figs. 17 and 18 rather than Fig. 16.
Finally, unhulled rice group 0 is distributed on the right side of the sorting plate (1), and brown rice group B is distributed on the left side.

In the case of FIG. 18, a blank space is formed on the right side, but in the embodiment of the present invention, the sorting plate (1) is inclined at an α angle as shown in FIG. There is no division.

The present invention is as described above, and particularly includes the following.

Countless irregularities (7) are formed on the surface of the separate plate (1), and the profile of the sorting plate +11 is approximately square, with one side of the front and rear sides being the supply side (2) and the other side being the discharge side (31, One side of the left and right side is a teratogenic side (5), and the other side is a non-teratogenic side (6), and the sorting plate (1) is inclined with a discharge flow angle β in the front and rear direction, and the supply side of the sorting plate 11+ (2), teratogenic side (5), and non-teratogenic side (
6) has a side wall (4) that stands up at a nearly right angle, and a sorting plate (
1) A swing-type sorting device for unhulled rice and brown rice, which is equipped with a left-right reciprocating device that moves faster when moving towards the non-odogenic side (6) than when moving towards the odorogenic side (5). Since the present invention is a device, it is possible to perform sorting by swinging the sorting plate (1) horizontally instead of diagonally up and down, which solves the deficiencies of conventional sorting devices.
