[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising tray reinforcing tool for holding a flexible seedling raising tray.

[0002]

2. Description of the Related Art As shown in FIG. 4, for example, a seedling-raising tray (1) has a top wall (2) made of a material such as a synthetic resin and formed into a flat surface. Although (3) is recessed, this type of seedling raising tray has a flat top wall.
A flexible seedling raising tray that can be curved and deformed only by recessing the cell (3) in (2), and a hard seedling raising tray that is configured so that the entire tray is not deformable by providing reinforcing ribs and peripheral walls around the entire upper wall. There is.

When carrying a hard nursery tray, it is easy to handle because the tray itself is not easily deformed even if the middle portion of the left and right edges is lifted with both hands, and it is easy to handle the nursery tray just by placing it on a thick tree. The bottom of the cell (3) is not grounded, and air flows in and out through the drain hole (4) provided on this bottom, so the roots do not come out of the drain hole (4), etc. There is.

On the other hand, since the flexible seedling raising tray can bend and deform the entire upper wall (2), the seedlings raised in each cell (3) can be picked up by a transplanter and transplanted into a field. The seedlings that have been raised in a plug shape are bent into cells,
There is a great advantage that it can be easily extracted from (3).

Conventionally, this flexible seedling raising tray (1) is housed in a rigid shape-retaining box (20) which is not easily deformed as shown in FIG. 4 when shape retention is required without reinforcing the tray itself. Was being treated.

[0006]

However, the above-mentioned flexible seedling raising tray has the following problems in the seedling raising process because the tray itself is flexible.

1. When filling or sowing the soil in the cell (3), the container is easily deformed and the operation is not easy. For this reason, a large shape-keeping box (20) that can hold the whole seedling raising tray (1)
It must be housed in a large shape box (2
Since 0) is required, the cost is high.

2. If the seedling-growing tray (1) is not housed in the shape retention box (20), it will be deformed and the bottom of the container will be directly grounded.
It becomes difficult for air to flow in and out through the drain hole (4) provided at the bottom of the cell (3). As a result, the roots of the seedlings easily emerge from the drainage holes (4) during the raising of seedlings and propagate to the outside of the cell (3).
It becomes difficult to be extracted from (3). In addition, when the water is stored in the shape-retaining box (20), the drainage flowing out from the drainage hole (4) is stored in the shape-retaining box.
The water may be accumulated in (20) and block the drain hole (4), and in this case also, it becomes difficult for air to flow in and out through the drain hole (4), and the same problem occurs.

3. When placing the seedling raising tray (1) on the transplanter for transplanting the grown seedlings into the field, if the seedling raising tray is placed in the shape retaining box (20), the seedling raising tray retains its shape in the shape retaining box (20). Therefore, it cannot be bent and deformed, and the transplant operation cannot be performed smoothly. Therefore, if it is taken out from the shape retention box (20) and, for example, the left and right sides of the nursery tray (1) are lifted at the front and rear intermediate portions, both the front and rear ends of the nursery tray (1) hang down, and the entire tray becomes convex upward The seedling may be naturally dropped from each cell (3) that is curved and near both front and rear ends, which is not easy to handle.

The present invention solves the above problems and provides a seedling tray reinforcing device that can keep the shape of a flexible seedling tray at a low cost to prevent roots from coming out of the drainage hole and facilitate the handling of the seedling tray. The purpose is to provide.

[0011]

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises a reinforcement for trays for raising seedlings as follows. That is, a seedling-raising-tray reinforcement tool for retaining the shape of a flexible seedling-raising tray (1), in which a rigid rod-shaped support member (6) and an upper wall (2) of the seedling-raising tray (1) are attached and detached. The supporting member (6) has a length (L) substantially equal to the whole length (L) of the seedling raising tray (1), and the holding portion (8) for holding the seedlings at the holding portion (8). The tray upper wall (2) is sandwiched and the supporting member (6) is fixed to the seedling raising tray (1) so that the seedling raising tray (1) can be linearly supported over substantially the entire length (L). It is a thing.

[0012]

[Function] Since the reinforcement for trays for raising seedlings is fixed to the tray for raising seedlings (1) when filling and sowing with soil or during the seedling raising period,
The seedling raising tray (1) is linearly shaped over substantially the entire length (L). And a seedling raising tray for transplanting seedlings to fields (1)
When the seedling raising tray is placed on the transplanter, the reinforcing member for the seedling raising tray is removed, and the flexible seedling raising tray (1) can be deformed into a curved shape on the transplanter.

[0013]

The present invention has the following effects because it is constructed and operates as described above. (A) The support for the seedling raising tray has a simple structure in which the supporting member is made of a rigid material with a length substantially equal to the entire length of the seedling raising tray, and a sandwiching portion for sandwiching the upper wall of the seedling raising tray from above and below is provided. Therefore, it can be manufactured at a lower cost than the conventional shape-retaining box that houses the whole seedling raising tray.

(B) Since the seedling raising tray is held in a linear shape over substantially the entire length by the supporting member, it is easy to fill the soil and sow with a seeding machine, and the direction in which the reinforcement for the seedling raising tray is arranged. The bottom of the cell can be lifted from the ground simply by arranging a joist tree in the crossing direction and placing it on it, and air can be let in and out from the drain hole. As a result, the roots of the seedlings are wound in the cells without coming out of the holes, so that the seedlings grown in a plug shape at the time of transplantation can be easily picked from the cells.

(C) Even when the nursery tray is placed on a transplanter for transplanting the raised seedlings to a field, even if the left and right sides of the nursery tray are lifted at the front and rear intermediate portions thereof, the nursery tray supports are supported by the nursery tray reinforcement tools. The front and rear ends of the do not hang down. For this reason, since the seedlings do not naturally drop from the cell, the handling of the seedling raising tray is extremely easy.

(D) Since the sandwiching portion detachably sandwiches the upper wall of the seedling raising tray, it is possible to easily remove the seedling raising tray reinforcement tool from the seedling raising tray on the transplanter, and the seedling raising tray is flexible. Since it can be bent and deformed, the seedlings can be transplanted smoothly by the transplanter.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention. FIG. 1 is a partially cutaway perspective view of a seedling raising tray with a reinforcement for a seedling raising tray, and FIG. 2 is an enlarged vertical front view of an essential part. is there.

As shown in FIG. 1 or 2, seedling raising trays
(1) has a large number of seedling-growing cells (3) recessed in an upper wall (2) formed of a thin synthetic resin sheet, and a drainage hole (4) is transparently provided at the bottom of the cell (3). I am doing it.

In this seedling raising tray (1), reinforcing tools (5) for raising seedling trays are detachably fixed to the upper walls (2) of the left and right side edges along the longitudinal direction of the container.

The above-mentioned seedling raising tray reinforcing tool (5) has a supporting member (6) made of a hard synthetic resin and having a length substantially equal to the entire length (L) in the longitudinal direction of the seedling raising tray. 6) is composed of an upper support member (6a) and a lower support member (6b) arranged in parallel.

In the upper and lower support members (6a, 6b), one side edge (7, 7) along the length direction is connected and fixed by a side wall (9), and the other side edge (10, 10). ) Between them is open and the cross section is formed in a U shape. Also, the upper and lower support members (6a ・ 6
The gap between b) is narrowed between the side edges (10, 10) on the open side, so that the sandwiching part (8) is provided between the upper and lower support members (6a, 6b).
Is formed. Then, the seedling raising tray is attached to the sandwiching portion (8).
(1) The left and right ends of the upper wall (2) are inserted and sandwiched.

By mounting the reinforcing member (5) for the seedling raising tray on each of the left and right edges of the upper wall (2) of the seedling raising tray, the seedling raising tray (1) is straightened over the entire length (L) in the longitudinal direction. Supported in a shape.

Since the seedling-raising tray reinforcing device (5) is simply inserted by sandwiching the seedling-raising tray upper wall (2) between the side edges (10, 10) on the open side, the seedling-raising tray (1) ) Is placed on the transplanter and can be easily removed by pulling out the reinforcing tool (5) for raising seedlings from the upper wall (2) and reuse it with the raising trays (1) collected after the transplantation. be able to.

In this embodiment, since the reinforcing member for the seedling raising tray has a U-shaped cross section over the entire length, it can be easily manufactured by extrusion molding of a hard synthetic resin, for example. However, it is not necessary to provide the sandwiching portion over the entire length, and for example, the sandwiching portions may be partially provided at appropriate intervals so that the upper support member is provided at both front and rear end portions and the central portion.

FIG. 3 shows a second embodiment of the present invention and is a partially cutaway perspective view of a reinforcement for trays for raising seedlings.

In this embodiment, the reinforcing member for the seedling raising tray (5)
Is slightly longer than the total length (L) of the seedling raising tray (1). And, the upper and lower support members that constitute the support member (6)
(6a and 6b) are arranged in parallel with each other, and one end portion on the base end side
The parts (11, 11) are fixed to each other by the connecting part (13). Also, between the upper and lower support members (6a, 6b), a seedling raising tray
(1) There is a slight gap corresponding to the thickness of the upper wall (2), so that the upper and lower support members (6a, 6b) are sandwiched (8).
Is formed.

An engaging ring (14) is attached to the lower support member (6b) so as to be vertically rotatable at a portion near the tip (12) of the seedling raising tray reinforcement tool (5), and the upper support member (6a). This engaging ring
An engagement groove (15) for locking the (14) is formed on the upper surface.

The upper wall of the seedling raising tray (1) is located between the tip (12) of the reinforcing member (5) for raising seedlings and the upper and lower support members (6a, 6b).
(2) is inserted and the engaging ring (14) is rotated to engage the engaging groove (15).
This upper wall (2) is locked to the upper and lower support members.
The seedling raising tray (1) is sandwiched by the sandwiching portion (8) between (6a and 6b), and is linearly supported by the supporting member (6) over substantially the entire length (L).

The gap between the upper and lower support members does not have to be evenly provided, and for example, the upper support member may be formed in a wave shape that can be vertically swung to provide the sandwiching portion.

Further, in this embodiment, by attaching an engaging ring to the tip, the tip of the seedling-raising tray reinforcing tool is prevented from opening up and down due to the weight of the soil filled in the seedling-growing cells. When the reinforcing rib is provided to make the rigidity of the supporting member sufficiently high, it is not necessary to attach the engaging ring.

Further, when the engaging ring is not attached, it is not necessary to form the upper and lower support members in the same length,
For example, if the length of the lower support member is formed to be substantially equal to the entire length of the seedling raising tray to support the seedling raising tray, the length of the upper support member may be shorter than this. In this case, the tips of the upper and lower support members are not aligned, which facilitates mounting on the seedling raising tray upper wall.
