CONSTITUTION:When connected seedlings 1c carried with belts 12, 18 are nipped between press rollers 22, 23 and passed through, upper and lower tapes 29 are pressed, delivered with press rollers 22, 23 and bonded to the base end portions if the seedlings. The bonded seedlings are further pressed with carrying rollers 24, 26 and carried. The two side tapes 29 and the root portions of the seedlings between the tapes 29 are wound with a yarn 31 to integrally fix the tapes and the root portions of the seedlings. The tape portions of the belt-like seedlings 1f are successively nipped and cut with cutters into planting seedling portions 1g comprising approximately twelve or thirteen seedlings and subsequently planted in a field at prescribed intervals with the traveling of the frame, thereby facilitating the handling of the seedlings and permitting to continuously link the automatic feeding, automatic cutting and planting of the seedling for improving the efficiency of the work.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a method for dividing and planting strip-shaped rush seedlings.

<Conventional technology> Generally speaking, when the seeds of rushes are germinated, the quality of the culms of the next generation is unstable, so after harvesting, the seedlings are transplanted and collected after growth, and the stock is transplanted to Honda. Conventionally, for example, the lower end of the root and the upper part of the culm of a seedling that has grown to a diameter of about 1,100 z is cut off to form a short culm, which is divided manually and then mechanically planted, or the seedling is planted in continuous units using rhizomes in advance. There are known methods such as planting seedlings while mechanically cutting them, or planting seedlings while flattening them and scraping off a large number of piled up flattened plants with a beater.

<Problem to be solved by the invention> However, in general, new shoots of Ikusa seedlings germinate and grow in a spiral shape when viewed from above, centered on underground stems, so it is difficult to manually divide and cut the planted plants (seeds may be divided unevenly). In addition, manually dividing stocks is itself inefficient.

In addition, dividing plants by mechanical cutting has the disadvantage that it is not possible to obtain uniformly planted plants because the stem culms, underground rhizomes, and shoots grow unevenly.Furthermore, scraping and planting at the planting peak also has the disadvantage that split seedlings cannot be obtained. There are problems such as unevenness and damage to new shoots.

In addition, when conventional rush seedlings are fed to a planting machine, their properties are uneven and they do not have a fixed shape, making handling complicated and resulting in problems such as uneven splitting of seedlings and uneven planting as mentioned above. This resulted in uneven growth after planting and unevenness in rushes during harvest.

Means for Solving the Problems> The method of the present invention for solving the above problems is to bring a plurality of sheet-shaped seedlings ib, which are continuous by underground rhizomes, into contact with each other at their front and rear adjacent ends to form a strip. The rhizomes of the band-shaped connected seedlings 1c are joined by a tape-like connecting means 29, and the tape and each seedling 1b are fixed with sutures, adhesives, or other fixing means to form a continuous band-shaped seedling 1d, The method is characterized in that the strip-shaped seedlings 1d are sequentially divided and cut to the desired planting amount and then planted.

<Function> By arranging the front and rear ends of the sheet-like seedlings 1b adjacent to each other, they become the prototype of the band-like seedlings 1d, and the tape-like connecting means 29 is placed along the rhizome portion of the sheet-like seedlings 1b, and the seedlings are fixed with a fixing means 31 such as a thread. As a result, the entire seedling becomes a single band-shaped seedling, and the shoots of underground stems are also protected by this method of connecting and fixing.

Practical Examples To explain in detail the examples shown below, Fig. 2 shows a method for pressure side of rush seedlings. The seedlings 1a are supported by guide belts 3 which are rotatably supported in pairs so as to form a flow path 2 with a predetermined gap. 4. A basket-shaped loosening rotor with many longitudinal spokes. By passing through a pressure side device constituted by a pressure biasing roller 5, a pressure side seedling 1b in the form of a sheet having a thickness of approximately 2Q+ytx is formed.

As described above, the seedling 1a is loosened in advance by the basket-shaped rotor 4, so that the whole is loosened softly and rolled into a flat state without damaging the new shoots that have sprouted from the underground stem, and is further pressed by the rolling side roller 5. It is then adjusted to the final thickness.

FIG. 1 shows an outline of a method of forming the seedlings 1b into belt-shaped seedlings while connecting them with other seedlings 1b, and a taping device for this purpose.The taping device 11 has an uneven surface (not shown).
The belt 12 is wound around a roller 13.14 by a long endless support, which has a short presser foot heald 18 parallel to the belt 12 and on its front end, the front and rear ends of which are wound around a roller 16.17. Supported.

The receiver is between the belt 12 and the presser belt 18, and the rear end of the receiver is placed on the seedling holding part 18a on the rear upper surface of the belt 12.
A gap is formed in which the sequentially connected band-shaped seedlings 1c are partially overlapped with or in contact with the front end of the seedlings 1c to be sent forward while being pressed.

Said roller 13. 16 are driving rollers, and at the end of each of these roller shafts 19 and 21 there is a pressing roller 22 whose peripheral surface is wrapped with elastic rubber and which rotates at approximately the same circumferential speed as the belts 12 and 18. Further, in front of the rollers 13.22 and 16.23, there is a feed roller 24.2 that carries out the seedlings sent out from the pressing rollers 22.23 while holding them in the next process.
6 is pivotally supported with a fixed gap above and below. The feed rollers 24 and 26 have spur gear-like irregularities formed on their circumferential surfaces, and are both driven in a direction to feed the seedlings forward.

Above or below the pressing rollers 22 and 23, a guide roller 27 and a tape roller 28 are arranged and supported symmetrically on the road, and each tape roller 28 has a certain strength against water and a A tape 29 made of paper, cloth, or other material whose fiber bonds break down when immersed in water for a long period of time is wound and stocked.

And Bell) 12.18 connected seedlings sent by
c passes between the pressing rollers 22, 23, the upper and lower tapes 29, 29 are held between the pressing rollers 22, 23,
23 and the adhesive side thereof is drawn out so as to be adhered to the front and back surfaces of the rhizome portion of the connected seedling 1c in sequence. The roots of the rush seedlings protrude from the bottom of the tape 29,
The rush stem and the new shoots sprouting near its base end protrude from the top, and the connected seedlings with the tape 29 glued to the base end are further pressed by the next feed rollers 24 and 26 to ensure adhesion. They are sent out one after another while becoming stronger.

In the position between when the tape 29 is pressed and the next feed roller 24.26 is reached as described above, the tape 29 on both the front and back sides and the seedlings in between are fixed integrally with the thread 31. be exposed.

That is, the roller 2626 in the moving line of the connected seedlings 1c
22. Tape 2 is placed around the gap between the front and back of 23.
9, 29 and a rotary ring 32 made of a vibrator having its center at the flute between the tapes is provided rotatably at right angles to the movement line.

On the outer periphery of the rotating ring 32, three rolling wheels 33 circumscribed at both left and right sides of the lower part and at the center of the upper part are pivotally supported, and at least one of the lower rolling wheels 33, 33a, rotates as a driving wheel, and the rotating ring 32 is rotated counterclockwise when viewed from the rear.

On the inner periphery of the rotary ring 32, a divider 34 is provided that protrudes toward the center of the ring, as shown in the drawing, the side end facing the rotation direction is folded to form a wedge-shaped edge 348.

A thread reel 36 is rotatably supported in the divider 34, and a thread 3 wound around the thread reel 36 is rotatably supported.
1 passes through a vibrator-shaped yarn-dispensing nozzle 37 attached to the inner end of the divider 34 and is fed out toward the tape 29 between the rollers 23 and 26 as the rotary ring 32 rotates.

The feeding end of the thread 31 is fixed in advance to the tape 29 between the rollers 23 and 23 and to the seedling portion before starting the rotating ring 32, and when the rotating ring 32 is rotated while sequentially feeding the connected seedlings 1c forward. , the thread is fed out in the same way at the center of the ring, and the tape 29.29 on the front and back of the connected seedling 1c is
The tape 29, 29 and the rush seedlings therebetween are tied together in a spiral manner, and sent forward while forming a band-shaped seedling 1d.

At this time, in the illustrated example, the divider 34 is connected to the connected seedlings 1c.
The thread 31 rotates upward from the bottom of the stem of the rush and pushes through the stem of the rush from below, and the thread 31 is wrapped only around the tape 29 at the base of the rush without being obstructed by the stem of the rush. , its strength is adjusted by the resistance to unwinding the yarn 31 from the yarn reel 36.

As mentioned above, in the method of the present invention, the thread is paid out using the forward movement of the seedling and the rotation of the rotating ring 32.
There is no need to drive the thread reel 36, and sufficient winding can be achieved by applying resistance to the thread 31 by applying a brake or the like. In addition, since both movements are driven at a constant speed, the thread 31
The winding becomes uniform.

37 is a cutter that is rotatably supported on the side of the presser belt 18 and rotates at high speed.The cutter 37 is used to correct the irregularities in the ends of the joints that are left unaligned during the pressure side by cutting them to the specified size. This is the final height dimension.

The strip-shaped seedlings 1d continuously formed as described above can be sequentially rolled up as roll-shaped seedlings 1e as shown by imaginary lines in FIG. As shown by the solid line, the seedlings can be cut into strip-shaped strips 1f with the front and back lengths of about 50 cm. In this case, since the thread 31 is cut at the time of cutting, in order to prevent the thread 31 at the cut part from fraying, a thread stopper 41 is applied in advance using thread fixing tape or adhesive to fix the thread 31 at the cut part to the tape 29. (It is desirable.

Next, we will discuss the case where the above-mentioned strip-shaped seedlings If are planted using a planting machine. The strip-shaped seedlings 1f are placed in a seedling stand 43 and a planter case behind the main body 42 of a riding-on planting machine as shown in FIG. A planting section 47 consisting of a seedling tray 44 and a float 46 is connected to each other, and strip-shaped seedlings 1'' are placed horizontally in a plurality of rows on a seedling receiving section 48 at the upper end of the seedling platform 43.

The seedling tray 43 has a shallow angular (dish-shaped) cross section that accommodates the band-shaped seedlings 1' in the upper seedling receiving part 48, but the plane gradually rises as it descends downward, and at the lower end It is configured to form a groove-shaped guide portion 50 that guides the band-shaped seedling 1f upright and downward, and the band-shaped seedling 1f
has a structure in which the lower part is intermittently fed quantitatively (for example, to positions 15a+x) by a belt-like feeding device (not shown).

Then, the strip-shaped seedling if is cut at the lower end by cutting off the tape 29 part of the strip-shaped seedling 1f from the left and right with a cutter 49 in accordance with the feed amount, and the width is Q (see Fig. 1) for snowy roads. The seedlings are LSwx and are separated one after another as one group of planted seedlings having a cross section of about 20zz thick and around 12 to 13 stems, scraped with a beak 51, and planted at predetermined intervals as the machine travels.

It is preferable that the tape 29 in the above embodiment be adhered to the continuous seedling IC, but if it is to be fixed later with thread 31, it is not necessarily necessary to adhere it.On the contrary, if it is to be strongly adhered with an adhesive or the like, the tape may be attached to one side. In addition, although the rotating direction of the rotating ring 32 is shown in the rear view as being counterclockwise so that the Teviter 34 stably pushes apart the stems of the connected seedling ICs from below, it is also possible to rotate the rotating ring 32 in the opposite direction. be.

<Effects of the Invention> According to the method of the present invention configured as described above, since the seedlings form a very stable and regular band shape, the handling of the seedlings becomes extremely easy, and the automatic supply of planted seedlings becomes possible. Automatic cutting and planting can be performed continuously by interconnecting the system, which not only improves work efficiency, but also equalizes the diameter and number of seedlings planted, and evens out growth after planting. It has advantages such as ease of management and ease of management.

In particular, for band-shaped seedlings, the rhizome part is connected and fixed with a tape-like connecting means, so it is possible to divide the seedling by cutting only the tape and the rhizome at the same time. There is little concern that it will cause damage.

Furthermore, since the tape-like connecting means is fixed at the rhizome portion of the seedling, the fixation is stable, and there is an effect that sagging or loosening does not occur during handling of the band-shaped seedling.
