Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves sequentially transporting divided block-shaped seedlings of one plant to a planting area by sandwiching them between two continuous tapes at a predetermined interval. The present invention relates to a tape seedling planting device configured to plant seedlings in a planting section.

[Conventional technology]

Conventionally, this type of tape seedling planting device has a structure in which the tape seedlings transported to the planting section are placed in a continuous state at a predetermined position in the field without cutting the tape (
For example, JP-A No. 53-54542 (Fig. 5).

[Problem to be solved by the invention]

Therefore, as shown in Figure 5 of the above-mentioned publication, the block-shaped seedlings are planted in a row at the same intervals held between continuous tapes. ” will be decided at the time. By the way, it is desirable to minimize the spacing between adjacent block-shaped seedlings held between tapes in order to reduce the amount of tape used overall, but the minimum necessary spacing is necessary for planting spacing. However, there was a problem in that it was not possible to set the interval based only on the amount of tape used.

An object of the present invention is to provide a method that allows planting at predetermined intervals while reducing the overall amount of tape used.

[Means to solve the problem]

Characteristic configurations according to the present invention include: (1) the position where the block-shaped seedlings are held by the tape is set on the stem tip side a predetermined distance away from the roots of the block-shaped seedlings; A tape cutting mechanism is provided which separates one block-shaped seedling transported to the attachment part from the following block-shaped seedlings while being held between the tape and is integrated with the tape. (2) the tape is made of a material that naturally decomposes after planting; There are certain points and , and the effects are as follows.

[For production]

(b) The block-shaped seedlings that are conveyed to the planting section while being held between continuous tapes are cut by the tape cutting mechanism.
Each plant is bundled with tape and the tape is cut to separate it from the subsequent block-shaped seedlings. At this point of separation, the planting claws act on the block-shaped seedlings to plant them. In this case, "action" refers to the manner in which the planting claws either clamp or hold (apply) the roots of the block-shaped seedlings.

(b) Therefore, since we adopt a configuration in which block-shaped seedlings are separated one by one, no matter what the interval between block-shaped seedlings that are held between continuous tapes and transported to the planting section,
Planting with planting nails can be done at desired intervals. Furthermore, since there is no restriction on the interval between the tapes, the interval between the tapes can be reduced to minimize the amount of tape used.

(c) Also, since the position where the tape is held for block-shaped seedlings is set at the tip of the stem, which is a predetermined distance away from the roots,
When the cutting mechanism cuts the clamping tape, it acts at a distance from the root, so the root will not be damaged. Moreover, it is set in an area that does not affect the growth of new shoots.

(d) On the other hand, since the tape itself has the characteristics described in feature configuration (■), after planting, it unties the block-shaped seedlings through the action of disappearing and decomposing, so that the influence on the growth of the block-shaped seedlings can be eliminated. .

〔Effect of the invention〕

As a result of the effect (b), the amount of tape used can be reduced, and the planting interval can also be maintained at a sufficiently predetermined interval.

Moreover, even though the tape is cut, the tape can be held at a position that does not affect the roots, and since the tape itself decomposes after planting, it has little effect on subsequent growth. It is suitable for planting strawberry, which aims to grow by waiting for the growth of new shoots.

As shown in claim 2, since the movable blade of the tape cutting mechanism is provided integrally with the planting claw, the timing at which the planting claw acts at the same time or substantially simultaneously with cutting is automatically determined, and the cutting mechanism As in the case where is provided separately from the planted nail,
There is no need to adopt a complicated control structure using sensors to match the timing.

〔Example〕

The tape seedling creation device will be explained. As shown in FIG.
), two continuous tapes (2) and (3) sandwiching one block-shaped seedling (a), and both tapes (
2), a feeding roll (4) that feeds out (3) separately,
(5), both tapes (2), (3) block-shaped seedlings (a
), both tapes (2).

(3), the presser arm (6) for pasting together the block-shaped seedlings (a
) A tape seedling making device is constructed by arranging a tape seedling storage case (7) that stores both tapes (2) and (3) sandwiching the tape (2) and (3) in a folded state. In addition, the belt conveyor device (
For 1), the worker divides up the plants and inserts them one by one. Another method of storing the seedlings in the tape seedling storage case (7) in a tapered manner is to wrap them around a drum, but when wrapping them around a drum, the bedside is larger than the stem tip. The diameter of the tape on the bedside side becomes larger, and the tape wound around the drum becomes a truncated cone.
This is because the wound tape self-destructs, and this self-destruction phenomenon is to be avoided.

The tape seedling planting device (A) will be explained. As shown in Figure 1, this tape seedling planting device (8) is attached to the rear end of the traveling machine body (not shown) via an elevating link mechanism (8), and the driving part (not shown) on the traveling machine side is attached to the rear end of the traveling machine body (not shown).

The cutting mechanism (16) includes a movable tape cutting blade (14) provided on the side surface of the planting claw (13) and a fixed receiving blade (15) that receives the tapes (2) and (3) to be cut. When the planting claw (13) grasps the block-shaped seedling (a), the tape (2), (3) is wrapped around the stem end of the block-shaped seedling (a) at a predetermined interval from the root of the block-shaped seedling (a). is to be cut. The tip of the planting claw (13) serves as a seedling holding part (13a) that presses down the block-shaped seedling (a) from above and guides it to the planting site, and the cutting mechanism (16) determines the cutting timing. The timing at which the seedling holding part (13a) presses the seedlings may be at the same time or at different timings.

Therefore, the movable blade (14) is connected to the seedling holding part (13).
Since it is located closer to the proximal end than a), it does not invade the root region of the block-shaped seedling (a), and therefore does not cut the new shoot.

By the way, the tape width to be cut is one block-shaped seedling (
a) Approximately 40 m per hit. The cut block-shaped seedling (a) is guided to the planting site by being held down by the seedling holding part (13a) of the planting claw (13), and the root part of the block-shaped seedling (a) is circular. Arc-shaped guide (28
