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 differences between the present invention and 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 sectional view of a part of a sorting plate A of a known sorting device, and B is brown rice. Then, as shown in FIG. 1, when the brown rice B is placed on the sorting plate A and the sorting plate A is reciprocated in the direction of the arrow W, the brown rice B gradually moves in the direction of the arrow C.

This is because the surface of the sorting plate A is formed with countless irregularities.

Therefore, as shown in Fig. 2, a sorting plate A is formed, and its left and right ends D form upright side walls E' F to sort out the mixed grains of brown rice B (white grains) and unhulled rice G (black powder). When it is fed onto plate A and reciprocated many times in the direction of the KW arrow as described above, brown rice B grains gather on the side wall E on the shaking side due to the slight difference in their specific gravity, and vice versa. 0 groups of unhulled rice gather on the side,
The two are separated from each other. In Figure 2, the range indicated as m is where only brown rice B is distributed, the area indicated as m is an area where unhulled rice G and brown rice B are mixed to some extent, and the area indicated as m2 is an area where unhulled rice G is distributed. m3 is a blank area that occurs due to the incitement relationship.

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

The known example shown in FIGS. 4 and 5 is an improved example in which the blank space m3 formed on the sorting plate A is not generated, and the side wall E side of the sorting plate A in FIG. When it is lifted and tilted α as shown in the figure, if the α angle is appropriate, the blank portion m3 will disappear and the sorting effect will be improved. Figure 5 shows sorting plate A
This is a front view when the device is tilted, and all of the devices currently on the market are similar to the known example shown in FIG.

The present invention is an improvement on the above-mentioned sorting apparatus (particularly the one shown in FIG. 5) since it is unsatisfactory, and its defects are pointed out as follows.

That is, the known example has a defect in that it moves forward and backward in the direction of the W arrow. This is because the actual size of the illustrated sorting plate A is at least 1 i (height 1 m x width 1 m), and since Fig. 5 only shows the principle of the invention, the sorting plate A is one stage. Although it is only shown in the diagram, in reality there were at least five stages stacked one on top of the other, and the structure was such that extremely heavy items were sorted by shaking them diagonally up and down. Moreover, as clearly shown in Figure 4, the grains are densely distributed on the sorting plate A, and the total amount of grains distributed is at least 306, so (the sorting device )
+ (grain distribution of 30&) was being shaken by 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, requiring a surprisingly thick concrete floor on which sorting equipment was installed. Of course, the underframe I in FIG. 5 only illustrates the principle of the invention, so in reality,
In some cases, instead of a simple underframe as shown in FIG. 5, a case of a hulling device is used. Therefore, the strength of the case was required to be surprisingly strong.

Furthermore, the defect in the known example shown in FIG. 5 is because the separation shown in FIG. 4 cannot be achieved unless the uneven corners shown in the enlarged view of FIG. 1 are formed very sharply. , the uneven corners are formed sharply, but in this way,
The above-mentioned unevenness is surprisingly difficult because the thin iron plate is cut. In other words, the grain BG does not move toward the side wall E with just the force of pushing it up in the direction of the arrow W, so the unevenness is sharpened and the grain BG is pushed forward.

The present invention overcomes the above-mentioned deficiencies and also
This is a sorting device that is easy to handle and has excellent performance.

In the present invention, countless irregularities are formed on the surface of the sorting plate, the downward brittle shape of the sorting plate is approximately square, and the sorting plate is inclined at least in the front-back direction and has a discharge flow angle, A swing type sorting device for unhulled rice and brown rice is characterized in that the sorting plate has side walls that stand up at approximately right angles on the left and right sides, and a left and right reciprocating device is attached to the sorting plate so that the forward movement is faster than the backward movement. This is the gist of the invention.

To explain an embodiment of the present invention, (11 is a sorting plate. The plate +11 is made of a thin metal plate, synthetic resin, etc.) The plate (1) is formed into a substantially rectangular shape with a downward brittle shape. A preferred embodiment is a square or rectangular shape.As shown in the plan view of FIG. 8, the plate (11 is shown in the plan view of FIG. ), supply side (2) and side walls protruding upward on both left and right sides +4
1 f51 (61 is provided.

FIG. 12 shows a longitudinal section of a part of the plate (1).
7). As shown in FIG. 6, a supply hopper (8
) is provided. Since each of the embodiment drawings illustrates the principle of the invention, only one stage of the sorting plate (1) is shown, but it is free to form this into a multi-stage type. In that case, that is, in the case of a multi-stage type, a distribution device extending from the supply hopper (8) to the multi-stage sorting plate (11) is attached.

The sorting plate +11 is lower on the discharge side (3) and has a discharge flow angle β. This angle β is not a strong angle at which the grains naturally roll and are discharged, but is an angle at which the grains are discharged while maintaining a layered structure by reciprocating in the left and right direction as described later. The angle β is adjustable. The easiest way to adjust the angle β is to tilt the entire table, but it is of course possible to adjust only the sorting plate (1) by separating it.

However, below the sorting plate +11, a frame (9) is provided at intervals. Bearings αlOB are provided on the left and right sides of the underframe (9), and support rods 0z are provided on the bearing 010B.
Each lower end of 03 is pivotally supported. Also, sorting board fil
Bearing αna! 9 is provided, and the support rod Q2
Each upper end of fi3 is pivoted. As is clear from Fig. 9 and Fig. 1O, the bearing α10B is provided in pairs at the front and rear, so the underframe (9) and the sorting plate fil are connected by a total of four support rods fil (13<103). That will happen.

However, one end of the rod aη is pivotally fixed to the longitudinal shaft Q[9 which pivotally supports the bearing α4 and the upper end of the support rod a7J, and the other end of the rod a7 is pivoted to the tip of the crank α barrel. Ru.

The crank OB is fixed to the driving shaft 09, and the driving shaft O
A pulley handle is fixed to I. In this case, the relationship between the position of the driving shaft (II) and the rod αη, etc. is a so-called "quick return mechanism" in which either one moves faster in the relationship between forward motion and backward motion. The difference is that the forward movement is fast to move the entire grain, and the backward movement is slow to return only the surface layer.

In the figure, C11) is the unhulled rice outlet, @ is the brown rice outlet, (c)
is the mixed rice outlet.

Next, we will discuss the effect.

When a mixed rice of unhulled rice G and brown rice B is dropped from the supply hopper (8) to the supply side (2) of the sorting plate (11) and the motor rotates the pulley (A), the driving shaft 01 rotates, As shown in the figure, the driving shaft 09 is
Rotate to the right from 2 to A. Then, when the crank side whose base is fixed to the driving shaft Ql is in position A, the rod (171) is in the maximum extended position, so the support rod 02 is centered around the bearing 0. Tilt it to the left side to the maximum.However, when the crank QIID rotates to the position of the mouth,
In Fig. 11, the support rod α2 becomes straight, and when it rotates further and reaches the position C, the rod (17) moves the support rod 02.
tilt to the right as much as possible. Then, when you return to position A after passing through position 2, the support rod az will return to its original position.
In this case, the rotation angle of Iha, which is a backward movement, is larger than that of Hai, which is a forward movement, so as the support rod αLG3) moves, the sorting plate (11) moves as shown in FIGS. In other words, immediately after being fed from the supply hopper (8), it is as shown in Fig. 13, but this sorting plate (1) is suddenly separated by the reciprocating motion of the rice cooker shown in Fig. 11. When it moves to the left, the impulse causes the entire mixed rice to move to the left as shown in Figure 14. At this time, with just one movement, the vertical separation of brown rice B and unhulled rice G is completely separated. Although this is not done, little by little brown rice B, which has a heavy specific gravity, sinks to the lower layer, and unhulled rice G, which has a lighter specific gravity, floats to the upper layer.

When the sorting plate (1) slowly moves back in this state, since the movement is slow, only the surface layer above the dotted line slides and moves to the right, as shown in Figures 13 and 15. When compared, in Fig. 15, the unhulled rice G is slightly more drifted to the right side. When this is repeated dozens of times as shown in Figures 16 to 18, the brown rice B will gather on the left side and the unhulled rice G will gather on the right side and be separated, as shown in Figure 18.

The present invention is as described above, in which numerous irregularities (7) are formed on the surface of the sorting plate (1), the vertical shape of the original plate (1) is approximately square, and the original plate +11 has at least the following: It is inclined in the front-back direction and has a discharge flow angle β, and the left and right sides of the original plate (1) have side walls (51+6
1, and the original plate fi+ is equipped with a left-right reciprocating device that moves faster in the forward motion than in the backward motion. Since the sorting can be performed by simply horizontally rocking without rocking, defects in conventionally known materials can be improved.
