Abstract

PURPOSE:To simplify the arrangement of apparatuses by disposing a specific raking member near the separation point of a pair of tapes of a tape seedling in such a manner as to act to the culm base part of the crop seedling bundle transferred in a state sandwiched between the tapes. CONSTITUTION:A raking member 4 is placed in a freely rotatable state opposite to a point to separate tapes by the upper and lower rollers 11A (11B). The raking member 4 is arranged in a state to act to the culm base part of the rush seedling bundle separated by the upper and lower rollers. A supporting table 13 to support the middle part of the rush seedling bundle is attached to the ear-tip side of the raking member 4 and fixed to the top end of a transplantation guide member 5. The rush seedling bundle is thrown into the transplantation guide member 5 directing the culm base part downward.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that a bundle of crop seedlings is once held between tapes, and when the tape seedlings are unwound and planted, the seedlings are separated from the tape. This invention relates to a tape seedling separation device.

[Conventional technology]

When taking out a crop seedling bundle from a tape seedling and planting it, for example, as shown in FIG. A structure is adopted in which both tapes are separated at the delivery section to the planting guide section (5), and the crop seedling bundle is delivered to the planting guide section.

[Problem to be solved by the invention]

In order to separate this tape and reliably take out the crop seedling bundles, a special removal tool is required, especially since adhesives are often attached to the tape side, and the crops removed with this removal tool. In order to introduce a bundle of seedlings into the planting guide section that leads the plant head to the planting surface, it is necessary to provide a dedicated posture switching mechanism that switches the plant head to the leading position. This would result in a complicated equipment arrangement, such as the provision of two dedicated mechanisms at the intersection of the planting guide section facing the population.

The object of the present invention is to provide a mechanism for separating crop seedling bundles from tape (
In the embodiment, the object is to provide a device that can simplify the arrangement of equipment by making simple modifications to the scraper.

[Means to solve the problem]

■ A bundle of crop seedlings is sandwiched between two continuous tapes at a predetermined interval, and the two tapes with the seedlings sandwiched are superimposed and wound together to form a tape seedling, which is attached to a predetermined feeding mechanism. ■ A scraping body is provided near the separation point of both tapes to scrape and separate the seedlings that are released from the grip between the tapes and guide them to the planting guide; ■ This scraping The tapes are sandwiched between the two tapes and are arranged to act on the plant base side of the bunch of crop seedlings that are sent, and the effects are as follows.

[For production]

In other words, by forcibly scraping the crop seedling bundle with the scraper, it is possible to release the clamping state of both tapes and take it out, and also to scrape the crop seedling bundle held by both tapes on the plant base side. By acting on the inclusion body, the first
As shown in Fig. 2 and Fig. 2, the plant can be planted by first raking in the base side of the plant and then dropping it through the planting guide (5) in that position. In addition, even if the planting position is not changed only by the action of the raking body, it is possible to forcibly set the plant head to the leading position when feeding into the planting guide section, and the planting guide can be set in a different position. It is possible to avoid putting it into the department.

〔Effect of the invention〕

■ Therefore, the rake body can have the function of removing crop seedling bundles from both tapes and the posture setting function of inserting them into the planting guide section, and the tape separation part and the artificial part of the planting guide part can be The arrangement of equipment in areas close to each other can now be simplified.

(2) If the planting guide part is dropped in advance of the plant and the plant is planted as it is, no special planting mechanism is required, and the scraper can be used instead of the planting mechanism.

〔Example〕

We will omit the explanation of the tape seedling winding device here.
- Only the process of unwinding the tape seedlings and planting them will be explained.

As shown in Figure 1, at the rear end of the passenger traveling aircraft (1),
The tape seedling planting device (A
) is installed. This tape seedling planting device (A) includes plate-shaped brackets (2), (2), which are erected at a predetermined interval on the left and right and are detachable from the rear link of the elevating link, and the plate-shaped bracket (2).

A tape seedling feeding device (3) provided in (2);
It is supported by a scraping body (4) as a device for separating seedlings from the tape, a planting guide part (5) for dropping separated seedlings to the planting surface, and a rear link of an elevating link mechanism (17). A planting transmission case (6) that receives power from the traveling body (1), a grounding float (7) that is supported by the planting transmission case (6) in a vertically movable manner, and a grounding float (7) that is attached to this grounding float (7). It consists of a groove-making device (8) that forms a groove in which the bundle of separated rush grass seedlings dropped from the planting guide part (5) is pushed and placed. Although not shown in the drawings, a backfilling tool may be provided for backfilling the trench in order to make the bundle of strawberry seedlings dropped into the trench self-supporting.

The tape seedling dispensing device (3) includes an idling type dispensing roller (9) for attaching and dispensing tape seedlings that have been rolled up and formed;
The first and second tapes (
10A) and (10B).
IA), (IIB), and a first drive roller (10B) that separately winds the first tape (10A) and the second tape (10B).
12A) and a second drive roller (12B). As shown in Fig. 3, the upper roller (IIA) has a plurality of rod-shaped hook claws on the lateral side of the tape winding surface.
A protruding catch claw (lla) forcibly separates the bundle of strawberry seedlings held between the tapes.A catch claw (llb) is also formed on the lower roller (IIB) side, and both claws (lla) are formed on the lower roller (IIB) side. A configuration is adopted in which the strawberry seedling bundles are separated by the cooperation of lla) and llb. The upper and lower rollers (IIA), (
IIB) opposite the tape separation point by the scratching body (
4) is provided, and this scraping body (4) is rotatably supported on one plate-shaped bracket (2), and the strawberry seedlings are separated by the upper and lower rollers (IIA) and (IIB). One plate bracket (
2) It is placed off to the side. On the tip side of the raking body (4), a support stand (13) that supports the middle part of the rush seedling bundle that is raked by the raking body (4) is provided on the planting guide part (5). It is fixed to the end face and has a fulcrum function for the bundle of rice seedlings so that the bundle of rice seedlings is placed into the planting guide part (5) with the plant base side facing downward.

To explain the drive structure for the tape seedling feeding device (3), a manual gear (14) is fixed to the rotational drive shaft of the second drive roller (12B), and this manual gear is connected to the output gear of the planting transmission case (6). (15) to form a drive structure to the second drive roller (12B), and this second drive roller (12B)
and the first drive roller (12A) and the chain (1
6) Y1 tape seedling feeding device by transmission (3)
It constitutes a drive structure for. Therefore, by synchronously rotating the first and second drive rollers (12a) and (12B) at the same rotational speed, the first and second tapes (10A) are rotated, respectively.

While winding up the tape (10B), the tape seedlings can be fed out from the feeding roller (9).

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
