Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention holds a working seedling bundle with a tape once, and separates the seedling from the tape when the tape seedling wound with this tape is unwound and planted. The present invention relates to a tape seedling separation device.

[Conventional technology]

When picking up a crop seedling bundle from a tape seedling and planting it, for example, as shown in FIG. 1, attach the tape seedling to a roll as a feeding device (3), and feed the tape while holding the crop seedling bundle, The transfer section to the planting guide section (5) has a structure in which both tapes are separated, and the crop seedling bundle is delivered to the planting guide section.

[Problems to be Solved by the Invention]

In order to separate the tape and take out the crop seedling bundles, adhesives, etc. are often attached to the tape side, and a special take-out tool is required, and the crop taken out with this take-out tool is also necessary. In order to put the seedling bundle into the planting guide part that leads the plant base to the planting surface, it is necessary to install a dedicated posture switching mechanism that switches the plant base to the leading posture, and at the separation site of both tapes. It was supposed to bring about the complexity of the device arrangement configuration such as providing two dedicated mechanisms at the intersection where the entrance of the planting guide section faces.

It is an object of the present invention to provide a mechanism for separating a crop seedling bundle from a tape (a scraping body in the embodiment) that can be simply modified to simplify the arrangement of devices.

[Means for Solving the Problem] A crop seedling bundle is sandwiched with two continuous tapes at predetermined intervals, and two tapes sandwiching this seedling are overlapped to form a tape seedling that is integrally wound, A scraping body is provided near the point where the tape is attached to a predetermined feeding mechanism and unwinding, and near the separation point of both tapes, the seedlings that are released from the holding state by both tapes are scraped off and guided to the planting guide part. The point is that this scraped body is arranged so as to act on the root side of the crop seedling bundle that is sandwiched and sent by both tapes, and the action and effect are as follows.

[Work]

In other words, by forcing the crop seedling bundle by the scraping body, the sandwiched state of both tapes can be released and taken out, and the crop seedling bundle held by both tapes can be scraped on the root side. By acting on the inclusion, the first
As shown in FIG. 2 and FIG. 2, the planter side portion can be scraped in advance and dropped through the planting guide portion (5) in that posture to plant it. In addition, even if you do not switch to the planting posture only by the action of the scraping body like this,
It is possible to forcibly set the stock origin preceding posture when throwing into the planting guide section, and avoid throwing into the planting guide section in different postures.

[Effects of the Invention] Therefore, the scraping body can be provided with the function of removing the crop seedling bundle from both tapes and the posture setting function of putting it into the planting guide portion, and the tape separating portion and the planting guide can be provided. The arrangement of the equipment at the site close to the site entrance site can be simplified.

If the planting guide part is dropped and planted as it is, the planting mechanism is not required and the planting mechanism can be substituted with the scraped body in the previous period.

〔Example〕

Here, the description of the tape seedling winding device is omitted,
Only the process of unwinding the tape seedling once wound and planting will be explained.

As shown in FIG. 1, a tape seedling planting device (A) is attached to the rear end of the riding machine body (1) through an elevating link mechanism (17). This tape seedling planting device (A) comprises plate-like brackets (2), (2) which are erected at right and left predetermined intervals and which can be attached to and detached from a rear link of a lifting link, and the plate-like bracket.
(2), tape seedling feeding device (3) provided in (2),
A scraping body (4) as a device for separating seedlings from the tape,
Guide part for planting that drops the separated seedlings to the planting surface
(5), a planted transmission case (6) that receives power from the traveling vehicle body (1) supported by the rear link of the lifting link mechanism (17),
The grounding float (7) supported by the planting transmission case (6) so that it can move up and down, and the separated strawberries seedling bundle that is attached to this installation float (7) and dropped from the planting guide section (5). It comprises a grooving device (8) for forming a groove for pushing and mounting. still,
Although not shown, a backfill tool for backfilling the grooving groove may be provided in order to make the bundle of strawberries and seedlings dropped into the grooving groove self-supporting.

The tape seedling feeding device (3) includes a free-feeding feeding roller (9) for feeding a tape seedling that has been once wound and formed, and a first and second tape (10A) fed from the roller (9). ), (1
Upper and lower rollers (11A) and (11B) for separating and separating (0B), a first drive roller (12A) and a second drive roller (12B) for separately winding the first tape (10A) and the second tape (10B) Consists of. As shown in FIG. 3, the upper roller (11A) is provided with a plurality of rod-shaped hooking claws (11a) protruding laterally from the tape winding surface, and the hooking claws (11a) are held by the tape. Forcibly separates the strawberries seedling bundles that have been formed, and a locking claw (11b) is also formed on the lower roller (11B) side, and the strawberries seedlings bundle is separated by the cooperation of both nails (11a) and (11b). The structure is adopted. The upper and lower rollers (11A), (11B)
The scraping body (4) is arranged so as to face the tape separation point by the, and the scraping body (4) is rotatably supported by the plate-like bracket (2) on one side, and the upper and lower rollers ( 11A),
The plate bundles (2) are arranged side by side so as to act on the root side of the strawberries seedling bundle separated in (11B).
On the tip side of the scraping body (4), a support number (13) for supporting the middle part of the bundle of strawberry grass seedlings scratched by the scraping body (4).
Is fixed to the upper end surface of the planting guide part (5), and has a fulcrum function for the strawberries seedlings bundle so that the strawberries seedlings bundle is put into the planting guide part (5) with the plant base side facing downward. .

The drive structure for the tape seedling feeding device (3) will be described. The input gear is attached to the rotation drive shaft of the second drive roller (12B).
By fixing (14) and engaging the input gear with the output gear (15) of the planted transmission case (6), a drive structure for the second drive roller (12B) is formed and the second drive is also performed. By feeding the roller (12B) and the first drive roller (12A) to the chain (16), a tape seedling feeding device
It constitutes the drive structure for (3). Therefore, by synchronously rotating the first and second drive rollers (12a) and (12b) at the same rotational speed, the first and second tapes (10
The tape seedlings can be fed from the feeding roller (9) by winding A) and (10B).
