Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an apparatus for manufacturing belt-shaped seedlings for transplantation for planting or transplanting seedlings of rushes or the like to a field.

[Prior art and problems to be solved by the invention]
When planting seedlings such as rush grass, for example, when planting seedlings in the field, dig up the seedlings that have been cultivated in the nursery, and if the seedlings have about 3 to 10 new shoots, divide the seedlings into seedlings. They hand-planted each selected crop one by one, but the process was time-consuming and required hard labor.

By the way, in such cases, if you plant seedlings that have no new buds or only a few, if the new buds are damaged for some reason, the seedlings will wither and die. There will be a stock shortage. Therefore, it is especially important to work on the plants with the utmost care so that they will have the appropriate number of new shoots and become seedlings. The work involved in dividing the seedlings to be planted is closely related to yield and quality, so carefully and rationally dividing the plants based on the new shoots is the first step that will lead to increased yields of high-quality seedlings and is extremely important. be.

By the way, in the past, this planting process was attempted to be done mechanically, including the work on the seedlings, as described in Japanese Patent Laid-Open No. 61-15, for example.
It is known from the publication No. 610. In other words, in this method, the seedlings placed in the seedling tank were forcibly torn out of the seedlings using the separating claws, and then transferred to the planting claws and planted in the field. However, with this method, the planted seedlings are forcibly torn off with separating claws from the clustered seedlings with sprouting new shoots, so the new shoots may be damaged during tearing off, or there may be no new shoots at all. It often happens that parts of the plant are torn off, and this poses a problem because, as mentioned above, the plant does not take root, but actually becomes a defective plant, resulting in a significant decrease in yield.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has been devised for the purpose of providing a device for manufacturing band-shaped seedlings for transplantation that can eliminate these drawbacks. The apparatus for manufacturing belt-shaped seedlings for transplantation includes a transport means for transporting the seedlings set in parallel at a predetermined interval, and an adhesive tape attached to the seedlings from both sides. The seedlings are supplied and adhered to each other, and for planting, the seedlings are sandwiched and held between adhesive tapes to form a strip-shaped seedling connected in a series, and the formed strip-shaped seedlings are collected by winding them up. The invention is characterized by comprising a collection means for collecting information.

Furthermore, in the present invention, the planting is carried out by means of transferring seedlings set in parallel with a predetermined interval, and the planting is carried out by means of transferring seedlings, which are set in parallel with a predetermined interval. The adhesive tape supply path may be formed in the gap between the left and right transfer plates.

According to the present invention, with this configuration, new shoots are effectively protected and transplanted seedlings with extremely high survival rates can be obtained.

[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a machine for producing transplanted seedlings for rush grass, and on a base frame 1a of the machine 1, sprockets 3 and 4 are supported on the left and right sides, respectively, at the front and rear in the direction of conveyance, which will be described later. . The sprockets 3 on the left and right front sides (transfer end side) are integrally supported on a support shaft 5, and the sprockets 4 on the left and right rear sides (transfer start end side) are integrally supported on a support shaft 6. An input boolean is further pivotally supported at one end. On the other hand, 8 is an electric motor that is attached to the base frame 1a, and a transmission belt 10 is suspended between a drive boolean IJ 9 provided on the motor shaft of the electric motor 8 and an input boolean for interlocking operation. connected.

Further, endless transfer chains 11 are suspended between the left and right front and rear sprockets 3.4, and on the outer periphery of the left and right transfer chains 11 are approximately trapezoidal transfer devices 12.12a.
are installed in parallel with a predetermined spacing, but the left and right transfer devices 12.12a are provided so that their centers are substantially coincident and face each other with a gap, and in the embodiment, the right side A receiving plate 12b is provided at the outer end of the transfer device 12a to receive the roots of the seedlings. Then, for unit planting with new shoots picked from the lump-like seedlings that have been cut out from the nursery, washed the roots, and cut the roots and stems to the required length, the strawberry seedlings P to the plants are transferred to the left and right transfer device 12. 12a, and this set portion is formed long from the transfer start end side to the intermediate portion of the transfer chino 11.

On the other hand, a forming means for forming a band-shaped seedling is configured closer to the transfer terminal end than the set portion position of the transfer chino 11.

That is, the base frame 1a is provided with pressure rollers 13 facing each other up and down on the transfer start end side, and feed rollers 14 facing up and down on the end side, and the feed rollers 14
At the upper and lower sides of the drum 15, roll tape materials 15a wrapped with adhesive tape 15 whose surface is coated with adhesive are attached to freely rotatable drums 15b. The upper and lower adhesive tapes 15 are then pulled out through the tension roller 16, and the adhesive surfaces of the upper and lower pressure rollers 13 face each other and are integrally adhered.
After that, it is wound up and collected on a winding drum 17 provided on the base frame 1a, as will be described later.

Further, transmission sprockets 18 and 19 are integrally fixed to the end of the support shaft 5 on the opposite side from the side on which the input bolief is fixed. A driven sprocket 22 provided on the winding shaft 21, on which a hole is removably attached in the axial direction, is interlocked and connected via a transmission chain 20, and the other transmission sprocket 19 and the support shaft 14a of the lower feed roller 14 It is interlocked and connected to a driven sprocket 24 provided at , via a transmission chain 23 .

On the other hand, transmission sprockets 25 are further fixed to the support shafts 14a of the upper and lower pressure rollers 14, and these sprockets 25 and the support shafts 13 of the upper and lower pressure rollers 13
The transmission sprocket 26 provided at a is the transmission chaino 26a.
The upper and lower support shafts 13a are also interlocked and connected through a transmission gear 27, and as described above, the movement of the transfer chino 1 due to the drive of the motor 8 is
1, the pressure roller 13, the feed roller 14, and the winding drum 17 rotate in conjunction with the seedling transfer, but in this case, the feed roller 14 has: It has a large diameter. Further, the winding speed of the winding drum 17 is controlled so as to be faster than the circumferential speed of the feed roller 14, and the winding shaft 21 is provided with a mechanism (not shown) that freely rotates under frictional braking. It is being

In the embodiment of the present invention configured as described above, first, as a preliminary preparation, a lump-like seedling is prepared by cutting it from the seedbed, washing the roots, and cutting the root and stem to the required length. Roll tape 15 with upper and lower adhesive tape 15
Pull out the pressure rollers 13 from the
, and is wound onto the winding drum 17 via the feed roller 14. In that case, for example, by leaving the lower tape 15 on the adhesive surface of the upper tape 15 without sticking it, and attaching it to the drum surface of the winding drum 17 with adhesive, the winding can be secured without shifting. I can wear it. With the preliminary preparations completed in this way, unit planting with new shoots picked from the prepared seedlings is carried out by transferring the strawberry seedlings P to the plants to each transfer device 12.
．． Set to 12a. When the motor 8 is driven and the transfer chino 11 is transferred by the stroke set for planting seedlings, the pressure roller 13, feed roller 14, and winding drum 17 rotate in synchronization with this. As a result, the set strawberry seedlings P are wound and collected on the winding drum 17 as continuous belt-shaped seedlings with a predetermined interval, with the center part being adhesively held by the adhesive tape 15 from both upper and lower sides. It turns out. The strip-shaped seedlings produced in this manner are then taken to the field and transplanted using a transplanter as appropriate.

As described above, in the embodiment of the present invention, it is possible to easily produce a series of continuous strip-shaped seedlings using the adhesive tape 15 in a state where the seedlings are planted at predetermined intervals. The work of picking the seedlings and setting them on the transfer device 12.12a is a manual process that can be carried out by the Ministry of Works and others while confirming that the seedlings are properly planted with new buds. However, in this set planting process, the process of holding the seedlings between the adhesive tapes 15 is carried out quickly and reliably by mechanical means, and therefore it is possible to produce a large number of strip-shaped seedlings in a short time, and the process of holding the seedlings with the adhesive tape 15 is carried out quickly and reliably. It is possible to effectively protect the roots where there are roots, and therefore, when planted in the field, it has excellent rooting ability and the occurrence of absent plants can be reliably prevented.

Moreover, this one uses a transfer device 12 in which the seedlings are set for planting.
．． 12a is divided into left and right sides with their centers aligned, and a supply path for the adhesive tape 15 is formed in the middle, and the transfer device 12a on the root side is provided with a plate 12b for receiving the root. When planting, seedlings can be set in an orderly manner based on the root by setting the seedlings with their roots abutting against the support board 12b, and the holding position of the adhesive tape 15 is also at a constant position based on the root, resulting in high precision. You will be able to prepare seedlings.

In addition, the band-shaped seedlings using the adhesive tape 15 are thin and, for example, when wrapped around the winding drum 17 as in the embodiment, a large number of seedlings can be collected even if the volume is small, and the seedlings can be planted in large quantities. It is also easy to transport from the production site to the field. Furthermore, in this case, the planted seedlings are securely held by the adhesive action of the adhesive tape 15, so even if the seedlings are handled roughly during transportation, problems such as seedlings falling out or shifting of the holding position will not occur. Prevented. Incidentally, adhesive tape 1
As for 5, if you use a material such as paper and coated with adhesive, even if you cut the tape part of the strip seedling at a specified pitch and plant it with the tape still attached. As time passes, the adhesive strength decreases and the adhesive tape 15 peels off, and the paper corrodes and assimilates with the soil, so the tape material remains in the II field and may have a negative impact. This has the advantage of being able to prevent things from happening.

Furthermore, this device can be planted by setting the seedlings in the transfer device 12.12a, driving the motor for this set stroke, and then setting the seedlings again.This process is simple. This makes it possible to easily produce high-quality strip-shaped seedlings regardless of skill level. In order to make the motor drive correspond to the set stroke of the seedlings, for example, a detection switch is provided to detect the presence or absence of seedlings for set planting, and the motor drive is performed only when the detection switch detects the set seedlings. By configuring this setting, motor drive control can be conveniently automated. Here, the motor is driven by operating an actuation switch (not shown) provided at an appropriate position for easy operation of the base frame 1a, and the detection switch 29 is placed between the transfer devices 12 and 12a. It can be configured to be installed from the side. In addition, since planting can be done from either the left or right side, it is not a big job and two people can work from both sides, increasing efficiency when necessary.

Further, in the embodiment, the feed roller 14 has a larger diameter than the pressure roller 13, and is set to have a faster circumferential speed. Therefore, the pressure roller 13 and the feed roller 14
There is no problem such as the adhesive tape 15 loosening and disrupting tape feeding during the manufacturing process of the strip-shaped seedlings between the
This means that the tape can be fed in an orderly manner under constant tension. This means that the feed roller 14 and the winding drum 17
The same holds true for the relationship between the circumferential speeds. However, in this case,
Since the winding drum 17 side is set to idle while being subjected to frictional braking, there is no possibility that the tension force on the winding drum 17 side will be too strong and the tape 15 will tear in the middle of the produced band-shaped seedlings. Since the occurrence of defects is reliably avoided, there is no problem at all.

Furthermore, in order to prevent the set planting from disturbing the seedlings when the seedlings are fed to the pressure roller 13, a guide 30 is provided which is configured to be lower at the end of the transfer.
When planting seedlings that are simply lightly placed and set in a, the stems of the seedlings can be successively pressed against the bottom of the transfer device 12. This means that it will be possible to manufacture Moreover, in this case, the transfer device 12.12a has a trapezoidal shape with an open top and a bottom.

Although care has been taken to ensure that the correct set position is achieved by the above-mentioned pressing, it is further possible to set one piece 12c of the transfer device at either the transfer start end side or the transfer end side higher than the other side, as shown in FIG. By making the seedlings overlap with the adjacent ones, it is convenient because the set adjacent plantings have the advantage of being able to prevent seedlings from interfering with each other.

[Operations and Effects] In summary, the present invention includes a transport means for transporting seedlings set in parallel at predetermined intervals, and an adhesive tape is applied to the seedlings from both sides for the transported plantings. a strip-shaped seedling forming means for forming a series of strip-shaped seedlings by holding the seedlings between adhesive tapes and holding the seedlings between adhesive tapes for planting;
Since the machine is equipped with a collection means for collecting the V-shaped seedlings by winding them up, planting is carried out by rolling the seedlings at predetermined intervals in a series of strips using adhesive tape. Seedlings can be easily manufactured, and in the production of these strip-shaped seedlings, the work of picking the seedlings and setting them up is carried out by the Ministry of Works and others, and it is necessary to properly plant the seedlings with new buds. This is a manual process that can be carried out while checking the conditions, but this set planting process, in which the seedlings are held between adhesive tapes, is done quickly and reliably by mechanical means, which means that a large amount of seedlings can be planted in a short period of time. It is possible to produce strip-shaped seedlings, and the roots with new shoots can be effectively protected. Therefore, when planted in the field, they have excellent rooting ability and the occurrence of absent plants can be reliably prevented.

Moreover, in the seedling transfer means, the seedlings are set on a pair of transfer plates arranged with a gap between the left and right transfer plates so that their centers substantially coincide with each other, and the seedlings are set in a pair of transfer plates with a gap between the left and right transfer plates. An adhesive tape supply route is formed on the
It is possible to reliably produce band-shaped seedlings while effectively protecting the roots where the new shoots are located without having any adverse effect on them.
