Description

The present invention relates to a processing device for improving the water absorption of beans and other seeds.

Among the large amount of beans, what is called "stone beans" is mixed. Stone beans are beans that have extremely low water absorption and hardly absorb water. Since such stone beans do not absorb water even after being steamed, they remain hard and are mixed with other beans that have been steamed, which causes the quality of the steamed beans to deteriorate as a whole. .. Also, when cultivating beans as seeds, there is a high probability that stone beans will not germinate due to their low water absorption.
Since stone beans are the same in appearance as other beans, it is difficult to distinguish stone beans from a large amount of beans and extract only stone beans. Therefore, instead of removing the stone beans, a treatment device for improving the water absorption of the stone beans has been proposed, and an example thereof is described in JP-A-2008-154464.

FIG. 22 is a schematic view of the processing apparatus 10 described in the same publication.
The processing apparatus 10 shown in FIG. 22 has a gap between the storage container 3 for storing the seeds 8, the flexible member 2 attached to the bottom surface of the storage container 3, and the flexible member 2 directly under the flexible member 2. The table 1 which is arranged open and has a micro-projection member (not shown) formed on the surface, the collection container 5 which houses the table 1 inside, and the table 1 and the collection container 5 are moved horizontally. It includes a drive member (not shown).
An inverted conical slope is formed in the storage container 3, and a passage hole 7 is formed in the center of the storage container 3. The passage hole 7 penetrates the storage container 3 and the flexible member 2.

The seed 8 placed in the storage container 3 slides down on the slope toward the passage hole 7, passes through the passage hole 7, and falls on the surface of the table 1 on which the microprojection member is formed. The surface of the table 1 is inclined downward toward the peripheral portion. Therefore, the seed 8 that has fallen on the table 1 starts moving toward the peripheral portion of the table 1 and enters the gap between the flexible member 2 and the microprojection member. The distance between the flexible member 2 and the microprojection member is set to be slightly shorter than the average diameter of the seed 8.
When the seed 8 enters the gap between the flexible member 2 and the microprojection member, the flexible member 2 is recessed inward by the seed 8, and as a result, the seed 8 is lightly pressed from above. In this state, the table 1 and the collection container 5 move horizontally by the driving member. Since the seed 8 is pressed from above by the flexible member 2, it does not skid with respect to the horizontal movement of the table 1 and thus the microprojection member, and rolls on the surface on which the microprojection member is formed.

Since the surface on which the microprojection member is formed is inclined downward toward the peripheral portion, the seed 8 rolls on the microprojection member several times and then gradually moves to the peripheral portion of the platform 1 to finally move to the peripheral portion. It falls from the outer edge of the table 1 into the inside of the collection container 5.
As described above, micropores are formed on the surface of many seeds 8 including stone beans by the microprojection members.

Japanese Unexamined Patent Publication No. 2008-1544464

However, the conventional processing apparatus 10 shown in FIG. 22 has the following problems.
The first problem is that the variety of seed 8 sizes cannot be dealt with.
In the processing apparatus 10 shown in FIG. 22, the distance between the apex of the microprojection member formed on the surface of the table 1 and the surface of the flexible member 2 is the smallest at the center of the table 1 and the smallest at the peripheral edge. It is large, but overall it is almost constant.

Therefore, for example, seeds having a diameter smaller than this distance are not pressed downward by the flexible member 2. Therefore, such seeds only roll on the surface of the pedestal 1 toward the peripheral portion of the pedestal 1, and the microprotrusion members do not form micropores on the surface of the seed. Further, even if the diameter of the seed is larger than the above distance, it can be dealt with to some extent by the flexibility of the flexible member 2, but when a seed having a size that cannot be dealt with by the flexibility of the flexible member 2 is thrown in, the table is introduced. It is caught between 1 and the flexible member 2 and cannot move, which causes a malfunction of the processing device 10.
As described above, the processing apparatus 10 shown in FIG. 22 has a drawback that it is not always possible to form micropores on the surface of the seed depending on the size of the seed 8.

The second problem is that the seed 8 may not move on the surface of the table 1 toward the peripheral portion of the table 1.
It is due to the weight of the seed 8 that the seed 8 moves on the surface of the table 1 toward the peripheral portion. For example, if a relatively lightweight seed pierces a microprojection member, the seed cannot move under its own weight, which causes the gap between the table 1 and the flexible member 2 to be clogged.
As described above, in the processing apparatus 10 shown in FIG. 22, even if micropores are already formed on the surface of the seed 8, the seed 8 may not move smoothly.
The present invention has been made in view of the above-mentioned problems in the conventional processing device 10 shown in FIG. 22, and it is intended to provide a seed processing device capable of solving these problems. The purpose.

In one embodiment of the processing apparatus according to the present invention, the second main body is formed with a through hole having an inner diameter larger than the diameter of the connecting shaft, and the connecting shaft passes through the through hole. It is a feature.

The shape in which the first main body and the second main body engage with each other is, for example, an annular protrusion formed on either one of the first main body and the second main body about the rotation axis thereof. It may consist of a recess formed on the other side to which the protrusion can be fitted.
In one embodiment, the processing apparatus according to the present invention further includes a connecting shaft and a self-aligning bearing, the first main body is connected to the connecting shaft, and the second main body is the same. It is characterized in that it is supported by the connecting shaft via a self-aligning bearing.
In one embodiment, the processing apparatus according to the present invention further includes a sleeve fixed to the connecting shaft, a pressing member for pressing the sleeve in a direction toward the second main body, and a plurality of pins . A plurality of holes are formed at positions corresponding to each of the bottom surface of the second main body and the sleeve, the pin is inserted into each of the plurality of holes, and the sleeve is the first. (2) Even when the rotation axis of the main body is tilted, the second main body is supported via the bottom surface of the second main body via the pin .

(First embodiment)
1 (A) and 1 (B) are schematic views showing the principle of the processing apparatus 100 for making small holes in the surface of seeds according to the first embodiment of the present invention, and FIG. 1 (A) is a processing diagram. A vertical cross section of the apparatus 100, FIG. 1B is a plan view of the processing apparatus 100.
As shown in FIG. 1A, the processing apparatus 100 according to the present embodiment has a first main body 110 having a first surface 111, a second main body 120 having a second surface 121, and a first main body 110. A motor or other driving means (not shown) for rotating the second main body 120 around the central axis 112, and a motor or other driving means (not shown) for rotating the second main body 120 around the central axis 122. ing.

The first body 110 has a conical shape, and therefore the first surface 111 has a conical shape. The first main body 110 is arranged so that the central axis 112 passing through the apex thereof faces the horizontal direction, or the planar bottom surface 110a of the first main body 110 faces the vertical direction.
A plurality of convex bodies 130 are formed in a matrix on the first surface 111 of the first main body 110. The convex body 130 has a sharp tip to the extent that a small hole can be formed in the surface of the seed 160 to be processed by the processing apparatus 100. For example, the convex body 130 can be formed in a conical shape or a needle shape.

The second main body 120 has a conical shape having the same shape as the first main body 110, and therefore the second surface 121 has a conical shape. The central axis 112 of the first main body 110 is oriented in the horizontal direction, whereas the central axis 122 of the second main body 120 is predetermined with respect to the horizontal direction or with respect to the central axis 112 of the first main body 110. It is arranged at an angle of α (for example, 3 degrees). In other words, in the central axis 122 of the second main body 120, one point of the central axis 122 is on the central axis 112 of the first main body 110, and the central axis 112 of the first main body 110 extends in the direction in which the central axis 122 extends. It is arranged so that it does not match the extending direction.
A plurality of convex bodies 150 similar to the convex body 130 are formed in a matrix on the second surface 121 of the second main body 120.

The first main body 110 and the second main body 120 are arranged so as to face each other so that their vertices are substantially in contact with each other or slightly separated from each other. Therefore, a space 140 having a V-shaped vertical cross section is formed between the first main body 110 and the second main body 120. As will be described later, the seed 160 to be treated is thrown into the V-shaped space 140 from above, and the first surface 111 of the first main body 110 and the second surface 121 of the second main body 120 are charged in the space 140. It is sandwiched between and.
The processing device 100 having the above structure operates as follows.
Initially, the first main body 110 and the second main body 120 are stationary. After that, both motors are operated to rotate the first main body 110 and the second main body 120 in the same direction. For example, as shown by the arrow 101 in FIG. 1B, the first main body 110 and the second main body 120 are rotated in the clockwise direction when viewed from the bottom surface 120a side of the second main body 120.

After that, beans and other seeds 160 are thrown into the V-shaped space 140 formed between the first main body 110 and the second main body 120 from above. As shown in FIG. 1 (B), the seed 160 is charged into the V-shaped space 140 in the input region R1. The charging region R1 is a region between the vertical direction and a direction at a predetermined angle (for example, 30 to 50 degrees) counterclockwise from the vertical direction, and in this region, the first surface 111 and the second surface 111. The seed 160 is charged when the distance to the surface 121 is relatively large. As shown in FIG. 1A, the introduced seed 160 is in a state of being sandwiched between the first surface 111 and the second surface 121.

Since the first main body 110 and the second main body 120 are rotated clockwise, the seed 160 is also rotated clockwise while being sandwiched between the first main body 110 and the second main body 120, and FIG. 1 (B) is shown. As shown in, in the perforated region R2, a small hole is formed in the surface of the seed 160. The perforated region R2 is a region between two directions at predetermined angles (for example, 15 to 25 degrees, respectively) in both the clockwise and counterclockwise directions from the horizontal direction, and in this region, the first surface 111 and the first surface 111. Since the distance between the two surfaces 121 is relatively small, the convex bodies 130 and 150 bite into the surface of the seed 160, and small holes are formed on the surface of the seed 160.
After this, the seed 160 shifts to the falling region R3, in which the seed 160 falls downward by its own weight. The drop region R3 is a region between the vertical direction and a direction at a predetermined angle (for example, 30 to 50 degrees) clockwise from the vertical direction, and in this region, the first surface 111 and the second surface 111. The distance to the surface 121 is relatively large. Therefore, the seed 160 is released from the state of being sandwiched between the first surface 111 and the second surface 121, and falls downward by its own weight (the input, drilling, and falling of the seed 160 will be described in detail later). ..

The charging area R1, the drilling area R2, and the falling area R3 are examples, and the positions of the seed 160 loading, drilling, and dropping are not limited thereto.
A container (not shown) is arranged below the processing device 100, and the dropped seeds 160 are stored inside the container.
As described above, the central axis 122 of the second main body 120 is tilted by a predetermined angle α (for example, 3 degrees) with respect to the central axis 112 of the first main body 110 (or in the horizontal direction). Therefore, when the second main body 120 is rotated around its central axis 122, the central axis 122 rotates so as to form a conical shape around the apex of the second main body 120. Therefore, while the first main body 110 and the second main body 120 are rotating, the distance between the first surface 111 of the first main body 110 and the second surface 121 of the second main body 120 is not constant. It does not fluctuate within the range corresponding to the inclination angle of the central axis 122. Specifically, as shown in FIG. 1A, assuming that a point located on the second surface 121 on the horizontal line passing through an arbitrary point 113 on the first surface 111 is a point 123, the second point is When the central axis 122 of the main body 120 is located above the horizontal direction, the distance between the two points 113 and 123 is relatively wide, and conversely, the central axis 122 of the second main body 120 is located above the horizontal direction. When located below, the distance between the two points 113 and 123 is relatively narrow.

As described above, while the first main body 110 and the second main body 120 are rotating, the convex body 130 formed on the first surface 111 and the convex formed on the second surface 121 are formed. It repeatedly approaches and separates from the shape 150. Therefore, on the surface of the seed 160 sandwiched between the first surface 111 and the second surface 121, the convex body 130 is formed while the seed 160 moves from the input position 160A to the drop position 160B. And a number of small holes are drilled according to the placement density of 150.
As shown in FIG. 1 (A), the contact point with the first surface 111 when sandwiched between the first surface 111 and the second surface 121 at the loading position 160A when the seed 160 is charged. The distance between the contact point with the second surface 121 is 161A, and the similar distance at the position 160B is 161B. In a state where the central axis 122 of the second main body 120 is inclined upward from the horizontal direction (state shown in FIG. 1A), 161B> 161A.

That is, while the seed 160 moves from the input position 160A to the drop position 160B, the convex bodies 130 and 150 bite into the surface of the seed 160 by the length of (161B-161A), so that the surface of the seed 160 Is formed with a small hole having a depth of (161B-161A).
According to the processing apparatus 100 according to the present embodiment, small holes (or dents) are formed on the surface of the seed 160 as described above.
Since the first main body 110 and the second main body 120 are continuously rotated, even if the seeds 160 are continuously charged, the seeds 160 can be continuously transported from the charging position 160A to the falling position 160B. Therefore, it is possible to continuously make small holes in the surface of a plurality of seeds 160.

The processing apparatus 100 according to the present embodiment has the following effects on the conventional processing apparatus 10 shown in FIG. 22.
In the conventional processing apparatus 10 shown in FIG. 22, the distance between the apex of the microprojection member formed on the surface of the table 1 and the surface of the flexible member 2 is maintained to be substantially constant. The processing apparatus 10 of the above has a problem that it cannot cope with the variety of sizes of the seeds 8.
On the other hand, in the processing apparatus 100 according to the present embodiment, the size of the seed 160 does not matter.
In the processing apparatus 100 according to the present embodiment, the conical first main body 110 and the second main body 120 are arranged so as to face each other, and a V-shaped space 140 is formed between them. As long as the seed 160 has a size that can be put into the V-shaped space 140, it is possible to make a small hole in the seed 160 of any size. Specifically, the minimum width of the V-shaped space 140 is equal to the distance (nearly zero) between the vertices of the first main body 110 and the second main body 120, and the maximum width of the V-shaped space 140 is the first main body 110 and It is equal to the distance between the outer edges of the bottom surfaces 110a and 120a of the second main body 120. Any size of seed 160 can be accommodated in the V-shaped space 140 as long as the seed 160 has a size between the minimum width and the maximum width of the V-shaped space 140. Since it is possible to make small holes in the surface, the range of the size of the seed 160 that can be processed is much larger than that of the conventional processing apparatus 10 shown in FIG.

Further, in the conventional processing apparatus 10 shown in FIG. 22, it is not always possible to form micropores on the surface of the seed 8 depending on the size of the seed 8. On the other hand, according to the processing apparatus 100 according to the present embodiment, if the seed 160 has a size between the minimum width and the maximum width of the V-shaped space 140, the seed 160 has any size. However, it is possible to make small holes.
Further, in the conventional processing apparatus 10 shown in FIG. 22, there is a problem that the seed 8 may not move on the surface of the table 1 toward the peripheral portion of the table 1.
On the other hand, in the processing apparatus 100 according to the present embodiment, the seed 160 is forcibly moved from the input position 160A to the drop position 160B in a state of being sandwiched between the first main body 110 and the second main body 120. Therefore, the seed 160 surely moves to the drop position 160B and then falls downward. That is, unlike the conventional processing device 10, the processing device 100 according to the present embodiment makes it possible to reliably move the seed 160 to the drop position.

The processing apparatus 100 according to the present embodiment is not limited to the above structure, and various modifications can be made without departing from the operating principle.
In the processing apparatus 100 according to the present embodiment, the convex bodies 130 and 150 are formed on both the first surface 111 and the second surface 121, respectively, but the first surface 111 and the second surface 121 are formed. It is not always necessary to form the convex bodies 130 and 150 on both sides of the above. It is also possible to form the convex body 130 or 150 on only one of the first surface 111 and the second surface 121.
In the present embodiment, both the first main body 110 and the second main body 120 are formed in a conical shape, but for example, one or both of the first main body 110 and the second main body 120 may be formed in a truncated cone shape. Is. In other words, the first main body 110 and the second main body 120 may include at least a part of the conical shape.

Further, the arrangement of the convex bodies 130 and 150 is not limited to the matrix shape. The arrangement of the convex bodies 130 and 150 is arbitrary. The convex bodies 130 and 150 may be randomly arranged, or instead of arranging a plurality of single convex bodies 130 and 150, for example, a linear protrusion having a triangular vertical cross section is first. It is also possible to arrange them in a spiral shape around the vertices of the main body 110 and the second main body 120.
In the processing apparatus 100 according to the present embodiment, both the first main body 110 and the second main body 120 are rotated around the central axes 112 and 122, respectively, but both the first main body 110 and the second main body 120 are rotated. It is not always necessary to rotate. It is also possible to rotate only one of them. For example, it is also possible to fix the first main body 110 in a stationary state and rotate only the second main body 120.

The angle at which the central axis 122 of the second main body 120 is tilted with respect to the horizontal direction is generally preferably 2 degrees to 15 degrees, but the tilt angle can also be determined according to the size and hardness of the seed 160. .. The value of the difference (161B-161A) between the distances 161B and 161A increases as the tilt angle of the central axis 122 increases (161B = 161A when the tilt angle is 0, so the value of 161B-161A is 0). ). For example, when the seed 160 to be treated is relatively large or the seed 160 is relatively hard, if the inclination angle of the central axis 122 is increased, the value of 161B-161A, that is, the surface of the seed 160 is increased.

The shapes of the first surface 111 of the first main body 110 and the second surface 121 of the second main body 120 are not limited to the cones, planes, and spherical surfaces shown above, and seeds 160 can be sandwiched. Any shape can be adopted as long as it is a shape. For example, an arc-shaped curved surface, a combination of a slope and a flat surface, a stepped shape, a combination of a flat surface and a curved surface, an uneven surface, a combination of curved surfaces having different curvatures, and the like can be used.
As described above, the seed 160 falls downward from the V-shaped space 140 due to its own weight, but in order to drop the seed 160 more reliably, the seed 160 is forcibly scraped off from the V-shaped space 140. It is also possible to place a scraper 415.

FIG. 6 is a schematic view showing a state in which the scraper 415 is arranged.
The scraper 415 is arranged inside the V-shaped space 140 in the area of the lower half of the first main body 110 and the second main body 120. For example, the scraper 415 is made of a V-shaped flat plate according to the shape of the V-shaped space 140, and is set to a size that covers most of the area of the V-shaped space 140. Therefore, when the seed 160 that has rotated together with the first main body 110 and the second main body 120 while being sandwiched between the first main body 110 and the second main body 120 reaches the scraper 415, it collides with the scraper 415 and the arrow. As shown in 170, it falls downward.
By providing the scraper 415 in this way, the seed 160C that has been processed to make a small hole can be forcibly dropped downward and reliably separated from the processing apparatus.

7, 8 and 9 are schematic views showing the process of charging, drilling and dropping the seed 160 into the processing device 100A (see FIG. 2). Hereinafter, with reference to FIGS. 7 to 9, the process from the seed 160 being put into the processing apparatus 100A to the perforation process and the downward fall will be described.
Since the central axis of the second main body 120 is inclined with respect to the horizontal direction H, as shown in FIG. 7, the distance between the first main body 110 and the second main body 120 accompanies the rotation of the second main body 120. Change. For example, the distance between the first main body 110 and the second main body 120 is maximum at the outer circumference S1 (one end of an arbitrary diameter of the second main body 120) of the second main body 120 and minimum at the outer circumference S2 (the other end of the diameter). It shall be.

The seed 160 is charged into the V-shaped space 140 by using the charging chute 180. The throwing chute 180 is installed at an angle within a range of 30 to 45 degrees with respect to the horizontal direction H, and is installed toward the apex 120A of the second main body 120. A V-shaped groove (not shown) is formed in the input chute 180, and the seed 160 slides down (or rolls down) into the V-shaped space 140 along this groove.
A scraper 415 is installed below the throwing chute 180 along the horizontal direction H.
When the seed 160 is charged into the position 1601 in the charging chute 180, the seed 160 slides down into the V-shaped space 140 at the position 1603 via the position 1602 and is sandwiched between the first main body 110 and the second main body 120.

As the second body 120 rotates clockwise, the seed 160 reaches position 1605, which is approximately horizontally above, from position 1603 through position 1604. While the seed 160 is rotating from position 1603 to position 1605, the distance between the first body 110 and the second body 120 at position 1603 and between the first body 110 and the second body 120 at position 1605. Convex bodies 130 and 150 bite into the surface of the seed 160 by a length equal to the difference from the distance. That is, a small hole is formed on the surface of the seed 160.
After this, the seed 160 rotates from position 1605 to position 1606, during which the convex bodies 130 and 150 gradually escape from the surface of the seed 160. The seed 160 that has reached position 1606 collides with the scraper 415 and falls to position 1607.
The above is one cycle of inputting, drilling and dropping seeds 160. This cycle is carried out continuously for a plurality of seeds 160.

Next, with reference to FIGS. 8 and 9, the amount (length) and angle at which the convex bodies 130 and 150 bite into the surface of the seed 160 will be described.
As shown in FIG. 8, in the state before the rotation central axis of the second main body 120 is tilted (the central axis of the first main body 110 and the central axis of the second main body 120 are parallel to each other), the second main body The distance between the outer edge of the first main body 110 and the outer edge of the second main body 120 at one end of the 120 (one end of an arbitrary diameter) is D1, and the first main body at the other end of the second main body 120 (the other end of the same diameter). Let D2 be the distance between the outer edge of 110 and the outer edge of the second main body 120, and let Dx be the absolute value of the difference (D1-D2) when there is a difference between the distance D1 and the distance D2.
| D1-D2 | = Dx

After tilting the central axis of the second main body 120 with respect to the horizontal direction H, the second main body 120 is rotated with respect to the first main body 110, and when the distance D1 is narrowed by, for example, 1 mm, the distance D2 is conversely 1 mm. As it expands, Dx becomes 2 mm.
1- (-1) = 2 mm
If the throwing chute 180 is installed at an angle of 45 degrees with respect to the horizontal direction H, the throwing direction of the seed 160 will be tilted by 45 degrees with respect to the horizontal direction H. The moving distance of the first surface 111 of the first main body 110 at the intermediate position Ia is 25 than the moving distance at the outer edge Ib of the first main body 110 (the position of the maximum distance between the first main body 110 and the second main body 120). % Become smaller.
45/180 = 0.25 = 25%
Therefore, the moving distance at the intermediate position Ia is G × (1-0.25) = G × 0.75.
(The meaning of G will be described later).

For example, it is assumed that the convex bodies 130 and 150 make a small hole with a depth of 0.75 mm on the surface of the seed 160.
As shown in FIG. 9, the distance from the outer edge of the first main body 110 (left end in FIG. 9) to the apex of the second main body 120 is F1, and the distance from the outer edge of the first main body 110 to the center of the seed 160 is F2. .. For example, as shown in FIG. 9, when the seed 160 is in a position where F1: F2 = 2: 1, one end of the second main body 120 (the left end or the right end of FIG. 9) is caused by the rotation of the second main body 120. If the seed 160 is also moved upward by the distance G (unit: mm), the seed 160 is also moved upward by the distance G (that is, toward the first main body 110), so that the convex bodies 130 and 150 are the seed 160. The length that cuts into the surface of is G × 0.75 / 2
Will be.

Since the distance between the first main body 110 and the second main body 120 at the position 1603 is 1/2 of the same distance at the position Ia, the convex bodies 130 and 150 when the seed 160 moves from the position 1603 to the position 1605. The amount (length) of the seeds that bite into the surface of the seed 160 is G × 0.75 / 2.
Will be.
For example, when the second main body 120 has a conical shape with a maximum diameter (bottom diameter) of 200 mm, in order to make a hole with a depth of 1.0 mm on the surface of the seed 160,
G x 0.75 / 2 = 1
From the above equation, it is necessary to set G = 2.667 mm.

The circumference of the second main body 120 is calculated by the following equation.
π x 200 = 3.14 x 200 = 628 mm
Since the moving distance G is 2.667 mm, the moving angle can be obtained by the following equation.
360 / (628 / 2.667) = 1.529 degrees In the above description, the processing device 100A was used as an example, but in other processing devices, the same loading / drilling / dropping process as described above is performed. Will be carried out.

(Second embodiment)
FIG. 10 is a cross-sectional view of the processing apparatus 200 according to the second embodiment of the present invention. 10 (A) and 10 (B) are vertical cross-sectional views of the processing device 200, and FIG. 10 (C) is a plan view of the processing device 200 when viewed from the right direction of FIG. 10 (B).
The processing apparatus 200 according to the present embodiment embodies the processing apparatus 100 according to the first embodiment shown in FIG.
The processing device 200 according to the present embodiment includes a first main body 110, a second main body 120, a rigid connecting shaft 210, a rubber bush 220, a ring 230 for holding the rubber bush 220, a sleeve 240, and an interval adjusting mechanism. It has 250 and.

The first main body 110 and the second main body 120 in the present embodiment are set to have a truncated cone shape, unlike the conical shape in the first embodiment. Therefore, the vertices of the first main body 110 and the second main body 120 are planar. The first main body 110 is formed with an annular protrusion 114 centered on its central axis 112. The vertical cross section of the protrusion 114 is triangular. An annular groove 124 is formed on the plane of the apex of the second main body 120. The vertical cross section of the groove 124 is triangular. The inner diameter of the protrusion 114 of the first main body 110 and the inner diameter of the groove 124 are set to be equal to each other, and the protrusion 114 is fitted into the groove 124. The protrusion 114 is fitted into the groove 124 so that the first main body 110 and the second main body 120 are engaged with each other.
The first main body 110 is formed with a flange portion 115 extending from the bottom surface 110a in the direction opposite to the apex, and the first main body 110 is further formed with a through hole 116 passing through the central axis 112 thereof. The inner diameter of the through hole 116 is equal to the outer diameter of the connecting shaft 210.

The second main body 120 is formed with a cavity 125 extending from the bottom surface 120a in the direction of the apex, and further, the second main body 120 also passes through the central axis 122 like the through hole 116 of the first main body 110. A through hole 126 is formed. The inner diameter of the through hole 126 is set to be larger than the outer diameter of the connecting shaft 210, and the connecting shaft 210 can be inclined to some extent inside the through hole 126.
A connecting shaft 210 is passed through these two through holes 116 and 126, and the first main body 110 and the second main body 120 are connected to each other via the connecting shaft 210 so as to face each other. Since the inner diameter of the through hole 126 of the second main body 120 is larger than the outer diameter of the connecting shaft 210, the second main body 120 is not supported by the connecting shaft 210, but the second main body 120 has the protrusion 114 of the first main body 110. By fitting into the groove 124 of the second main body 120, it is supported by the first main body 110, and thus by the connecting shaft 210, via the protrusion 114 and the groove 124, and further via the rubber bush 220 described later. ..

The first main body 110 is fixedly attached to the connecting shaft 210 by passing the screw 117 through the screw hole formed in the flange portion 115 up to the connecting shaft 210.
The rubber bush 220 is inserted into the hollow portion 125 of the second main body 120 in a state where the connecting shaft 210 passes through the inside thereof. The rubber bush 220 is pressed by the ring 230 and is in a compressed state. Further, the ring 230 is held by the sleeve 240. A screw hole is formed in the sleeve 240, and the sleeve 240 is fixed to the connecting shaft 210 by passing a screw 127 through the screw hole up to the connecting shaft 210. By fixing the sleeve 240 to the connecting shaft 210, the rubber bush 220 is fixed in a compressed state inside the cavity 125 of the second main body 120 via the ring 230 and the sleeve 240. Therefore, the rubber bush 220 exerts a force pushing the second main body 120 in the direction of the first main body 110 on the second main body 120.

The rubber bush 220 has enough elasticity (flexibility) to be able to be deformed to some extent inside the cavity 125 of the second main body 120.
The interval adjusting mechanism 250 includes a bolt 251 horizontally arranged above the first main body 110 and the second main body 120, a pair of nuts 252 attached near both ends of the bolt 251 and a pair of nuts 252, respectively. It is equipped with a cam follower 253 sandwiched between the two.
Each nut 252 can move in both left and right directions along the bolt 251. Each cam follower 253 is arranged so as to be in contact with the bottom surfaces 110a and 120a of the first main body 110 and the second main body 120.

For example, when the nut 252 located on the right side of FIG. 10 (A) is moved along the bolt 251 in the left direction (direction toward the first main body 110), the cam follower 253 also becomes as shown in FIG. 10 (B). Since it moves in the left direction together with the nut 252, the upper part of the second main body 120 is pushed in the left direction (direction toward the first main body 110), and the second main body 120 is tilted in the counterclockwise direction. It becomes. Since the inner diameter of the through hole 126 of the second main body 120 is larger than the outer diameter of the connecting shaft 210, even if the second main body 120 is tilted, the second main body 120 and the connecting shaft 210 do not interfere with each other, and further. Since the rubber bush 220 inside the cavity 125 is deformable, it is maintained in a state of absorbing the inclination of the second main body 120, that is, in a state of being deformed.

In this way, by adjusting the position of one (or both) of the pair of cam followers 253 via the nut 252, the central axis 122 of the second main body 120 is tilted in the horizontal direction at an arbitrary angle. It is possible to maintain.
The processing apparatus 200 according to the present embodiment having the above structure is used as follows.
First, as shown in FIG. 10A, the first main body 110 and the second main body 120 are connected via the connecting shaft 210, and the rubber bush 220, the ring 230, and the sleeve 240 are attached to the second main body 120. After that, the first main body 110 and the second main body 120 are fixed to the connecting shaft 210 with screws 117 and 127.

After that, the cam follower 253 located on the right side of FIG. 10A is moved in the left direction (direction toward the first main body 110). As a result, the central axis 122 of the second main body 120 is in an inclined state with respect to the horizontal direction. The tilt angle can be changed according to the amount of movement of the cam follower 253.
After that, the connecting shaft 210 is rotated clockwise (see FIG. 10C) by a motor (not shown). The first main body 110 rotates about the central axis 112 extending in the horizontal direction, while the second main body 120 rotates about the central axis 122 inclined in the horizontal direction. Next, by throwing the seed 160 into the V-shaped space 140 from above, a small hole can be made in the surface of the seed 160 as in the processing apparatus 100 according to the first embodiment.
The processing device 200 according to the second embodiment can also obtain the same effect as the processing device 100 according to the first embodiment.

The processing apparatus 200 according to the second embodiment is not limited to the above structure, and various modifications can be made.
The shapes of the first main body 110 and the second main body 120 can be changed as in the first to fourth modifications described above.
Further, instead of the rubber bush 220, it is also possible to use an elastic body or an elastic material having the same function as the rubber bush 220.
11 (A) and 11 (B) are vertical cross-sectional views of the processing apparatus 200A according to the first modification of the processing apparatus 200 according to the second embodiment, which are FIGS. 10 (A) and 10 (B), respectively. It is a cross-sectional view corresponding to).

As shown in FIGS. 11 (A) and 11 (B), the first surface 111A having a flat surface is formed in the same manner as in the first modification of the first embodiment in which the shape of the first main body 110 is shown in FIG. It can be a cylindrical shape or a truncated cone shape (in the example shown in FIGS. 11 (A) and 11 (B), a truncated cone shape).
Further, instead of the rubber bush 220, a spring 260 that exhibits the same function as the rubber bush 220 can be used.
The spring 260 is housed in the cavity 125 of the second main body 120 and is arranged outside the connecting shaft 210. The spring 260 exerts an elastic force on the second body 120 and the ring 230 in a direction that keeps them away from each other. As shown in FIG. 11B, it is possible to maintain the central axis 122 of the second main body 120 in a state of being inclined with respect to the horizontal direction even by using the spring 260.
The processing device 200A according to the present modification can also obtain the same effect as the processing device 200 according to the second embodiment.

A snap ring 129 is fitted inside the through hole 128. Further, a bearing holding ring 321 is fitted in the connecting shaft 310 so as to be in contact with the first main body 110. The self-aligning bearing 320 abuts on the snap ring 129 at one end (right end of FIG. 12 (A)) and abuts on the bearing holding ring 321 at the other end (left end of FIG. 12 (A)) with the snap ring 129. It is supported in a state of being sandwiched between the bearing holding ring 321 and the ring 321.
Further, the sleeve 330 fixed to the connecting shaft 310 via a screw abuts on one end of the self-aligning bearing 320 (the right end of FIG. 12A) and supports the self-aligning bearing 320 from the right end thereof. ..

In this way, the second main body 120 is supported by the connecting shaft 310 via the self-aligning bearing 320. The self-aligning bearing 320 refers to a bearing having a function of automatically tilting to support the shaft even if the centers of both ends of the shaft are deviated, the shaft is bent, or the shaft is bent.
The interval adjusting mechanism 340 is the same as the interval adjusting mechanism 250 in the second embodiment.
The processing apparatus 300 according to the present embodiment operates as follows.
First, as in the first embodiment, the central axis 122 of the second main body 120 is tilted in the horizontal direction via the spacing adjusting mechanism 340.

After that, a motor (not shown) is operated to rotate the second main body 120 around the central axis 122. Even if the second main body 120 rotates with the central shaft 122 tilted, the self-aligning bearing 320 functions to absorb the tilt of the central shaft 122. Therefore, the second main body 120 has the central shaft 122 with respect to the horizontal direction. It can continue to rotate smoothly while being tilted.
As described above, the processing apparatus 300 according to the first embodiment makes it possible to make small holes on the surface of the seed 160 like the processing apparatus 100 according to the first embodiment, and the processing apparatus according to the first embodiment. It exerts the same effect as the effect of 100.

The processing apparatus 400 according to the present embodiment is the processing apparatus 100 according to the first embodiment shown in FIG. 1, similarly to the processing apparatus 200 according to the second embodiment and the processing apparatus 300 according to the third embodiment. Is a concrete example of.
The processing device 400 according to the present embodiment has a sleeve 410 for the second main body, a connecting pin 4111, a rubber bush 420, and a ring for holding the rubber bush 420, as compared with the processing device 300 according to the third embodiment. 430 and are additionally provided.

A through hole 128 passing through the central axis 122 is formed in the second main body 120, and the self-aligning bearing 320 is fitted in the through hole 128. Inside the through hole 128, a protrusion 129 is formed so as to project toward the center of the through hole 128. A bearing holding ring 321 is fitted in the connecting shaft 310 so as to be in contact with the first main body 110. The self-aligning bearing 320 abuts on the protrusion 129 at one end (right end of FIG. 13 (A)) and abuts on the bearing holding ring 321 at the other end (left end of FIG. 13 (A)) with the protrusion 129. It is supported in a state of being sandwiched between the bearing holding ring 321 and the ring 321.
As described above, as in the case of the third embodiment, the second main body 120 is supported by the connecting shaft 310 via the self-aligning bearing 320.

The sleeve 410 for the second main body is attached to the connecting shaft 310 on the bottom surface 120a side of the second main body 120. A recess is formed in the sleeve 410 for the second main body, and the rubber bush 420 is loaded in the recess. The rubber bush 420 is pressed by the ring 430 in a compressed state, and the ring 430 is pressed by the sleeve 330 fixed to the connecting shaft 310 via the screw 331. As a result, the rubber bush 420 acts to press the sleeve 410 for the second main body against the second main body 120.
