Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a tape seedling transplanter for, for example, straw or rye, which exposes a plurality of crop seedling bundles to sunlight for a predetermined period in the longitudinal direction of the tape. A device is provided for separating the bundle of crop seedlings at a predetermined position from a tape seedling formed by holding and arranging the bundle of crop seedlings and sewing the bundle of crop seedlings to the tape with a thread, and a planting device for receiving and planting the bundle of separated crop seedlings. This article relates to a tape seedling transplanter equipped with a tape seedling transplanter.

[Conventional technology]

Conventionally, when configuring the separation device in the tape seedling transplanter, a winding roller is provided that winds up a tape holding a plurality of crop seedling bundles and a thread, respectively, and two winding rollers are provided to guide the thread and tape to the winding rollers. Two guide rollers were provided, and the two guide rollers were spaced apart from each other.

[Problem to be solved by the invention]

If the two guide rollers are installed apart from each other in this way, even if they are brought close to each other to a distance corresponding to the volume of the crop seedling bundle, the clamping force of both guide rollers against the tape seedlings will not be sufficient. If the tensile force applied to the thread by the thread take-up roller becomes strong, the point where the thread unravels from the tape will be on the upper side of the tape seedling transport than the separation point at both guide roller positions, so This causes the crop seedling bundles to separate from the tape, or even if they do not separate, the attachment posture is insufficient, resulting in a lack of smoothness in the planting work.

An object of the present invention is to provide a device that can stably move tape seedlings to a desired separation position by rationally arranging both guide rollers and attaching a simple mechanism to the guide rollers. It is in the point of doing.

[Means to solve the problem]

Characteristic configurations according to the present invention include: (1) The separating device includes a tape winding roller for winding the tape and a thread winding roller for winding the thread separated from the tape; A first guide roller that guides the tape to the winding roller to separate the proboscis seedling bundles and a second guide roller that guides the thread separated from the tape to the thread winding roller are connected to the first and second guide rollers. The guide rollers are arranged so as to sandwich the tape seedlings from both sides, and (1) at least one of the guide rollers is formed with a guide surface that comes into elastic contact with the tape seedlings. , its functions and effects are as follows.

[For production]

In other words, since the tape seedlings are held between the guide roll provided with the guide surface and the other guide roll, the thread pulled by the thread winding roll will loosen from the tape at the point where it passes the pinch point between these two guide rolls. Let's go. Moreover, even if the winding force and tension of the tape change, the tape seedlings are held between both guide rolls and are pressed elastically against the guide surface, so that the point at which the thread unravels is more easily conveyed than at the nipping point. It does not move to the side.

Therefore, the crop seedling bundle moves in a stable position sewn to the tape with the thread until it reaches the separation position by both guide rolls.

[Effects of the Invention] As a result, troubles such as the crop seedling bundle being separated from the tape before reaching the separation site or the attachment posture to the tape changing are eliminated, so there is no impact on subsequent planting work. In addition, since the guide surface of the roll has elasticity, it can sufficiently follow changes in the thickness of the tape seedlings due to the crop seedling bundles being arranged at predetermined intervals. Can securely hold the thread.

〔Example〕

The tape seedling transplanter (1) is once a tape seedling making device (not shown).
The tape seedlings created in step 1 are stored in the seedling storage case (2) in a zigzag manner with the top and bottom overlapping, and the tape seedlings are fed out from there and the crop seedling bundle (a) is separated from the tape (3) and planted. be.

The tape seedlings are a bunch of small crop seedlings (a) that have been manually divided from the mother plant against a single continuous tape (3), with the culm direction running along the width direction of the tape (3). Arranged at a predetermined interval in the longitudinal direction of the tape (3),
It is formed by sewing it onto the tape (3) using a sewing machine (not shown).

As shown in Fig. 1, the tape seedlings stored in the seedling storage case (2) are fed out downward via the guide roll (4) at the upper end of the seedling storage case (2), Droop down to 5). At this time, the crop seedling bundle (a) is delivered in a tilted posture along the lateral direction of the machine, and midway through, the crop seedling bundle (a) is turned into a tilted posture facing forward and backward.

As shown in FIG. 3, this hanging path is provided with a guide mechanism (25) that suppresses deviation of the tape seedling from the predetermined hanging path. A U-shaped guide body (26) that acts on the stem base side is fitted, and a U-shaped guide body (26) that acts on the stem base side is fitted, and the tape back side is brought into contact with and guided around the stem tip of the crop seedling bundle (a). It is configured by forming a wraparound part. Therefore, the tape seedlings can reliably follow the guide surface of the first tape guide roller (8) (described later) by this guide mechanism (25), and receive a reliable guide action. ing.

The separating device (5) includes a tape winding roller (6) for winding the tape (3), a thread winding roller (7) for unwinding and winding the sewing thread (10), and a separation section for the crop seedling bundle (a). a first driving guide roller (8) that guides the tape (3) from which the crop seedling bundle (a) has been released to the tape winding roller (6);
