Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is intended to plant rush that is the raw material for tatami mats, and to produce grass seedlings that cannot be applied to rush transplanters.
Concerning techniques for cutting the roots and stems of rush seedlings.

0002

BACKGROUND OF THE INVENTION Conventionally, technology regarding a rush transplanter for planting rush seedlings has been known, but there has been no technology regarding a mechanism for vertically cutting rush seedlings.

0003

[Problem to be solved by the invention] This is particularly because it is difficult to raise rush seedlings as seedling mats, and it is also difficult to plant young seedlings like paddy rice seedling mats, and they must be transplanted in a considerably stretched state. This is because the roots had grown too long and the stems had grown too long, so it was necessary to cut them. Also, it is difficult to plant rush seedlings densely, so in order to make it possible to plant them using a rush transplanter, it is necessary to remove the soil from the roots of the rush seedlings, level them, and adjust the length of the roots and stems. This was because it was necessary to prepare the seedlings and place them on the seedling stand of the rush transplanter. SUMMARY OF THE INVENTION An object of the present invention is to provide a mechanism for vertically cutting rush seedlings, which can mechanically cut the roots and stems, which were conventionally done manually.

0004

[Means for Solving the Problems] The problems to be solved by the present invention are as described above, and next, the means for solving the problems will be explained. In the upper and lower cutting mechanism that simultaneously cuts the roots and stems of the rush seedlings 1, the seedling conveyance mechanism that conveys the rush seedlings 1 to the cutting mechanism is composed of an upper conveyor belt 3 and a lower conveyor belt 2, and the upper conveyor belt 3 is connected to the lower conveyor belt 3. The upper conveyor belt 3, which is shorter than the conveyor belt 2 and on which the rush seedlings 1 are placed, is the seedling supply side;
It protrudes from the upper conveyor belt 3 on both sides of the conveyance of cut seedlings. Further, in the upper and lower cutting mechanism that simultaneously cuts the roots and stems of the rush seedlings 1, the seedling conveyance mechanism that conveys the rush seedlings 1 to the cutting mechanism is constituted by an upper conveyor belt 3 and a lower conveyor belt 2, and the upper conveyor belt 3 Belt rollers 20 and 23 around which the lower conveyor belt 2 is wound and belt rollers 19 and 20 around which the lower conveyor belt 2 is wound are arranged so as not to overlap vertically.

A front view of the four cutting blade parts of the cutting mechanism,
FIG. 10 is a front view showing the structure of the belt interval adjustment plate 30, FIG. 11 is a front view of the rush seedling 1 before cutting, and FIG. 12 is a front view of the rush seedling 1 after being cut by the top and bottom cutting mechanism for rush seedlings of the present invention. It is a diagram. As shown in FIGS. 11 and 12, the mechanism for cutting the rush seedlings up and down according to the present invention allows the rush seedlings 1 to take root when they have grown in the nursery to the growth state necessary for transplanting, are dug up, and are attached to a rush transplanter. Both the stem and the stem have grown too long, making it difficult to place them on the seedling stand of the rush transplanter, and also making it difficult to hold and transport them with the planting claws.・The roots and stems of rush seedlings 1 are cut to a simple shape that can be transported and planted. Then, in order to obtain a cut and transplanted seedling 1a, the cut root part 1b and the cut stem part 1c are cut off.

1, 2, and 3, the overall structure of the mechanism for vertically cutting rush seedlings will be explained. A seedling placement workbench 8 is constructed, and a seedling 1 to be dug up from a seedbed is placed on the seedling placement workbench 8. An operator is permanently placed on the seedling placement workbench 8, and the operator places a certain amount of rush seedlings 1 on the lower conveyor belt 2, and holds the rush seedlings 1 between the lower conveyor belt 2 and the upper conveyor belt 3. The seedling cutting mechanism is then conveyed to the seedling cutting mechanism formed by the cutting blade 4 and receiving blade 5. The upper parts of the seedling cutting mechanism part and the upper conveyor belt 3 part are covered with a cutting part safety cover 10. Inside the cutting section safety cover 10, the cut transplanted seedlings 1a cut by the cutting blade 4 and the receiving blade 5 are thrown into the cut transplanted seedling box 6 from the cut transplanted seedling discharge gutter 11. Also, inside the cutting section safety cover 10, cutting debris and mud that come out during cutting by the seedling cutting mechanism part fall from the hem of the cutting section safety cover 10, and the mud debris falling troughs 27, 27 on the left and right. From the part, the rush seedlings fall to the left and right of the top and bottom cutting mechanism. A drive motor 13 is disposed in a protected manner below the dirt falling gutter 27. In addition, the cut roots 1b and cut stems 1c that have been cut from the rush seedlings 1 fall from the mud-dropping troughs 27 and 27, but they also fall from the mud-dropping trough 12 and enter the mud-dropping box 7. Injected.

Next, referring to FIG. 4, a specific configuration will be explained. A lower conveyor belt 2, an upper conveyor belt 3, and a cutting blade 4 are driven from a drive motor 13 disposed at the lower part of the mechanism for vertically cutting rush seedlings. That is, pulleys 25 and 24 are fixed to the motor shaft of the drive motor 13, and the crank pulley 15 is driven by the pulley 24. A crank rod 9 is pivotally supported on the crank pulley 15 by a pin, and as the crank pulley 15 rotates, the crank rod 9 transmits reciprocating motion to the cutting blade 4. The central part of the cutting blade 4 is used alone, and the upper and lower ends are held together with the receiving blade 5 to cut the root part 1b of the rush seedling 1 and the cut stem part 1c.
It cuts the. Also, the pulley 25 of the drive motor 13
As a result, the deceleration pulleys 16 and 14 are driven, and the rotation after deceleration is transmitted from the pulley 14 to the pulley 17. A belt roller 19 of the lower conveyor belt 2 is driven by the pulley 17.

The lower conveyor belt 2 is longer than the upper conveyor belt 3, and is driven by a belt roller 19 on the driving side and by a belt roller 21 on the driven side. Also, the conveyor belt 3 above the pulley 17
The pulley 18 is rotated, and the belt roller 20 is driven by the pulley 18. The upper conveyor belt 3 supports the surface facing the lower conveyor belt 2 by two main belt rollers 20 and 23, and also includes guide belt rollers for providing a guide belt surface for guiding the conveyance and input of the rush seedlings 1. 22 are provided. With this configuration, the belt roller 2
3 and the guide belt roller 22, an inclined guide surface is formed into which the rush seedlings 1 can easily enter.

A pair of left and right seedling cutting mechanisms constituted by a cutting blade 4 and a receiving blade 5 are arranged between the belt rollers 20 and 23 and on the sides of the lower conveyor belt 2 and the upper conveyor belt 3. has been done. Therefore, only the portion of the rush seedling 1 sandwiched between the lower conveyor belt 2 and the upper conveyor belt 3 that protrudes between the upper and lower belts is cut by the seedling cutting mechanism. The cutting blade 4 and receiving blade 5 of the seedling cutting mechanism will be explained with reference to FIGS. 5, 6, and 9. Regarding the seedling cutting mechanism part which is usually composed of the cutting blade 4 and the receiving blade 5, the receiving blade 5 and the cutting blade 4 are normally provided over the entire cutting part, but in the present invention, the receiving blade 5 and the cutting blade 4 are provided over the entire cutting part. Only the upper and lower center portions of the blade 5 are omitted. Therefore, the upper and lower center portions are cut by the cutting blade 4. With this, the grass seedling 1 that you want to cut,
This eliminates the problem of the receiving blade 5 getting caught and creating resistance to conveyance. Although the cutting blade 4 is provided over the entire width, since cutting assistance cannot be received from the receiving blade 5, the blade must be sharp.

In FIGS. 7 and 8, the lower conveyor belt 2
The relationship between the length of the upper conveyor belt 3 and the length of the upper conveyor belt 3 is illustrated. That is, when comparing the conveying surface length a of the upper conveying belt 3 and the conveying surface length b of the lower conveying belt 2, a is configured to be smaller than b. Since the lower conveyor belt 2 also serves as a loading table, a space is required for the loading operation, so the input side of the rush seedlings 1 is lengthened in that area, and the output side of the cut and transplanted seedlings 1a is also lengthened. Cut and transplant seedlings 1
A is configured so that it does not rotate together with the upper conveyor belt 3. In addition, a belt roller 20 on the upper conveyor belt 3 side is placed inside the belt rollers 19 and 21 and at a position that does not vertically overlap with the belt rollers 19 and 21.
・23 is placed. In this way, belt roller 2
By shifting the positions of belt rollers 19 and 21 from the positions of belt rollers 19 and 21, the elasticity of the belt does not damage the seedlings, and both small and large plants can be transported without damage. In FIG. 10, the lower conveyor belt 2
An embodiment is disclosed in which the height of the portion is adjustable. By vertically adjusting the belt interval adjusting plate 30, the interval between the lower conveyor belt 2 and the upper conveyor belt 3 can be adjusted.

[Effects of the Invention] Since the present invention is constructed as described above, the following effects can be achieved. That is, since the configuration as in claim 1 allows the guide surface to be formed by the belt between the guide belt roller 22 and the belt roller 23, the operator can supply the rush seedlings 1 and the rush seedlings 1. This makes it easier to hold the paper between the lower conveyor belts 2. Further, since the lower conveyor belt 2 on the discharge side is configured to be longer than the upper conveyor belt 3, another conveyor belt can be connected continuously to the lower conveyor belt 2.
It is possible to transfer the seedlings to the seedling stand and discharge them until the next stage. Moreover, since the structure is configured as in claim 2, the rush seedlings 1 are not damaged between the lower conveyor belt 2 and the upper conveyor belt 3, and it is possible to hold and convey from small plants to large plants without damaging them.
