Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a microvibration grain sorting device.

(Prior Art) FIG. 1 is a sectional view of a discharge portion of a sorting apparatus described in Japanese Patent Publication No. 57-9872.

The structure of the sorting device is such that the plate surface of a square-shaped sorting plate is formed by a fine-grained surface, and is formed so as to oscillate obliquely up and down in the left-right direction as shown by a W reciprocating arrow in FIG. Have been. The left and right amplitude by the W arrow is about 40mm ~
It is about 50 mm, and the swinging feeling is loose, and the mixture of paddy rice and brown rice is sorted by giving such a reciprocating movement.

In addition, what is described in Japanese Patent Publication No. Sho 62-13075, which has a well-known structure, has a high inclined projection on one side formed on the entire plate surface of a square-shaped sorting plate, and a paddy rice outlet is provided on one of the front and rear sides of the sorting plate. Is formed, a brown rice outlet is formed on the other side of the front and rear sides, and a structure is shown in which the sorting plate is given an overall horizontal circular motion of about a radius of about 50 mm to separate the paddy and brown rice into each of the front and rear outlets. .

Also, in the publicly known Japanese Patent Publication No. Sho 62-19229, a high graded projection is formed on one side of a square sorting plate, and a rice rice outlet is formed on one of the front and rear sides of the sorting plate. On the other hand, there is shown a structure in which a brown rice outlet is formed, and the sorting plate is reciprocally oscillated on the left and right sides so as to separate paddy and brown rice back and forth.

(Problems to be Solved by the Invention) Mixed rice of unpolished rice and brown rice is placed on the sorting plate described in Japanese Patent Publication No. 57-9872 and rocked in the direction of the arrow W, as shown in FIG. However, brown rice gathers on the rocking side and unpolished rice gathers on the non-rolling side. However, it is noted that a lot of small rice is distributed in the brown rice on the rocking side. Tend to be distributed more.

However, neither small rice nor immature rice is distributed in a state of being mixed with brown rice, and a state in which only small rice is independently distributed does not occur. This phenomenon is the same in Japanese Patent Publication No. Sho 62-13075 and Japanese Patent Publication No. Sho 62-19229.

Therefore, the known sorting plate, small rice or immature rice,
Since it is mixed with other rice and extracted, a rotating net is required for sorting immature grains, a rotary shifter is required for sorting small rice, and indene is required for sorting small, medium and large grains. Needed a tet cylinder.

The rationale that small rice or immature rice cannot be sorted according to a known sorting plate is as follows. That is,
In FIG. 2, the sorting plate is moved up by about 50 mm from the lower right position A to the upper left position B. When the sorting plate is moved up by about 50 mm in this way, in the intermediate C position, both the brown rice and the small rice are equal and the whole grain is once. A phenomenon of being thrown into the air occurs, and the separated ones are mixed again at the intermediate C position, so that separation by large and small sizes cannot be completely performed.

Therefore, for the amplitude, 5m which is 1/10 of 50mm
I came up with the use of the micro-vibration of m. Also, regarding the direction of the micro-vibration,
This is not a fixed one direction but a two-way vibration (different direction vibration).

(Means for Solving the Problems) Accordingly, the present invention provides one of the front and rear sides of the rectangular sorting plate 1 on the supply side 2, the other side on the discharge side 3, and one of the left and right sides on the swinging side 4.
The other side is a non-oscillating side 5, and an inclined projection 6 with a high oscillating side is formed on the entire surface of the sorting plate 1, and the sorting plate 1 is surrounded by an upright wall 7 except for the discharge side 3. At
A microvibration grain sorter in which the sorting plate 1 is alternately provided with a horizontal tilt microvibration W 'thrusting toward the swinging side 4 and a horizontal tilt microvibration W' thrusting toward the non-swinging side 5. The configuration is as follows.

(Embodiment) FIG. 3 and subsequent drawings illustrate the configuration of the present invention.

Reference numeral 1 denotes a sorting plate, which is formed in a bird's-eye view rectangular shape as shown in FIG. 7, one side of the front and rear sides is a supply side 2, the other side of the front and rear sides is a discharge side 3, and the supply side 2 is viewed from the side. Slightly higher than the discharge side 3, the grain is configured to flow gradually in the direction of the discharge side 3 by vibration.

One of the left and right sides of the sorting plate 1 is a swinging side 4 and the other is a non-swinging side 5. On the sorting plate surface, an inclined projection 6 facing the swinging side 4 direction is formed on the entire surface. I do.

Around the supply side 2, the swinging side 4, and the non-swinging side 5,
An upright wall 7 is provided so that the grain does not spill out, but the discharge side 3 is opened over the entire width to discharge the grain. A small rice outlet 8 is located at a position closer to the swinging side 4 of the discharge side 3.
Is formed, then the unripe rice outlet 9 is formed, then the brown rice outlet 10 is formed, then the mixed rice outlet 11 is formed, and then the paddy rice outlet 12 is formed.

When the sorting plate 1 is made to reciprocate up and down obliquely toward the swinging side 4 as shown in FIG.
If the micro-vibration of about 5 mm, which is about 1/10 smaller than that in the figure, the phenomenon of C in the middle of FIG. 2 does not appear, the small rice and the brown rice layer are completely separated from each other by the fine amplitude.

FIG. 4 shows a situation where small rice 13 and immature rice 14 (larger rice than small rice) are separated by microvibration. When the sorting plate 1 repeats the micro-vibration in the W direction toward the swinging side 4, the small rice 13 and the immature rice 14 gather toward the swinging side 4. And
The small rice 13 in contact with the inclined protrusion 6 on the sorting plate 1 moves toward the swinging side 4 as shown by an arrow (a) each time it vibrates, and when further vibration is applied, the small rice 13 rises on the swinging side 4 When it rises as indicated by the arrow (b) against the wall 7 and is further vibrated, the small rice 13 circulates back to the upper layer as indicated by the arrow (c).

At this time, it is particularly desirable to move the immature rice 14 floating at the upper part as shown by the arrow (d) by utilizing the upper circulation phenomenon of the arrow (c) (the movement can be separated).
However, even if the small rice 13 circulates to return to the upper layer as shown by the arrow (c), the sorting plate 1 vibrates violently in the W direction as a whole, and the vibration wins, and the immature rice 14 moves to the arrow (d). It does not move like).

As described above, the immature rice 14 which does not easily move in the direction of the arrow (d) also moves relatively easily with a slight wind when the wind blows like e. This is based on the idea that vibration in the W 'direction, which is opposite to the vibration in the W direction, should be applied. Therefore, the present invention moves the immature rice 14 in the direction of the arrow (d). As means for moving, the oblique vertical swing of the sorting plate 1 is moved to W 'as shown by a white arrow.
Direction.

To explain with reference to the overall view of FIG. 7, the sorting plate 1 is kept until the grain supplied to the supply side 2 is discharged from the discharge side 3.
Are repeatedly subjected to a vertical vertical vibration W of about 5 mm in amplitude toward the swinging side 4 and a vertical vertical vibration W ′ of about 5 mm in amplitude toward the non-oscillating side 5.

In the state shown in FIG. 4, when the push-up motion of W 'is given, the push-up motion of W' is given equally to the small rice 13 in the lower layer and the immature rice 14 in the upper layer.
Since the direction of the inclined protrusion 6 is directed to the swinging side 4, the force of returning the small rice 13 in contact with the inclined protrusion 6 in the non-swinging side 5 direction is not so strong. On the other hand, the upper layer immature rice 14 receives a relatively large amount of force to move in the direction of the arrow (d), and is returned before the small rice 13.

By repeating this, by the time the grain group reaches the supply side 3 beyond the intermediate point of the sorting plate 1, as shown in FIG. 5, the small rice group 13 and the immature rice group 14 are clearly distinguished from each other. You will face each other.

In such a state, the immature rice 14 hardly pushes the small rice 13 and penetrates into the small rice 13 even when the thrusting movement in the W direction is given. Rather, the fifth group from the small rice group 13
A resistance force as shown in Fig. (C) is generated, and re-mixing is not performed. The boundary is further clarified and the material is taken out from the outlet.

The above separation phenomenon is not limited to small rice 13 and immature rice 14 but also appears between immature rice 14 and brown rice 15 and between brown rice 15 and paddy rice 16. There is a clear separation.

(Effect) On the sorting plate described in Japanese Patent Publication No. 57-9872, there is a phenomenon that small rice is distributed a lot in brown rice on the rocking side, and there is a tendency that immature rice is distributed next to small rice. . However, neither small rice nor immature rice is distributed in a state of being mixed with brown rice, and a state in which only small rice is independently distributed does not occur. This phenomenon is due to the well-known
The same applies to the one disclosed in Japanese Patent No. 3075 and the Japanese Patent Publication No. Sho 62-19229.

Therefore, the known sorting plate, small rice or immature rice,
Since it is mixed with other rice and extracted, a rotating net is required for sorting immature grains, a rotary shifter is required for sorting small rice, and indene is required for sorting small, medium, and large grains. Needed a tet cylinder.

However, according to the present invention, one side of the front and rear sides of the square-shaped separation plate 1 is set to the supply side 2, the other side is set to the discharge side 3, one of the left and right sides is set to the swinging side 4, and the other is set to the non-swinging side 5. An inclined projection 6 having a high swinging side is formed on the entire surface of the plate 1 and the sorting plate 1 is surrounded by an upright wall 7 except for the discharge side 3. Since the tilting microvibration W in the left-right direction and the tilting microvibration W ′ in the left-right direction rising toward the non-oscillating side 5 are alternately applied to the microvibration grain sorting device, By the push-up movement of W 'which is pushed up toward the rocking side 5, only the upper layer immature rice 14 is returned in the non-rocking side 5 direction, so that 13 small rice groups and 14 immature rice groups are clearly distinguished from each other. You will face each other. In such a state, even if a push-up motion in the W direction is given, the immature rice 14 hardly pushes the small rice 13 and penetrates into the small rice 13, and rather, from the group of small rice 13, FIG. C) will produce resistance,
Without re-mixing, the boundaries are increasingly defined and removed from the outlet.
