Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for raising seedlings, which is mounted on a seedling stand of a rice transplanter to grow mat-like seedlings to be planted in a field.

[0002]

2. Description of the Related Art As an apparatus for raising mat-like seedlings, for example, a resin-made seedling raising box disclosed in JP-A-2-219520 (5 in FIGS. 4 and 10 of the publication).
And a sheet member made of paper (1 in FIGS. 1 and 4 of the publication). In this publication, as shown in FIGS. 4 to 6, in a state where the sheet member is placed in the seedling raising box, bed soil is laid and seeded to cover the soil. In this state, the seedlings are germinated in the nursery room, and after germination of the seedlings, as shown in FIG. 9 of the above publication, the seedlings germinated from the nursery box and the sheet member are combined into one mat-like seedling. Take it out.

[0003]

The sheet member in the seedling raising device of the above publication is provided with a large number of conical portions and is used for growing middle seedlings and adult seedlings generally called pot seedlings. Is. And in recent years, the seedling-raising device that combines such a sheet member and a seedling-raising box, can be used for medium seedlings and adult seedlings in which seed paddy is sown in stripes, and for seedlings in which seed paddy is evenly sown. It is suggested to do so. As described above, when the mat-like seedlings are taken out from the seedling-raising box after the mat-like seedlings are grown by the seedling-raising box and the sheet member, a flat rake plate is prepared, and the tip of the rake plate is placed in The mat-like seedlings and the bottom of the seedling-growing box are separated by inserting the mat-like seedlings and the bottom of the seedling-growing box from the end, and the mat-like seedlings are scooped by the scooping plate and taken out from the seedling-growing box. When the mat-like seedlings are grown by the seedling-raising box and the sheet member in this way, it takes some time to take out the mat-like seedlings from the seedling-raising box, and there is room for improvement. An object of the present invention is to configure a mat-like seedling that can be easily taken out from the seedling-raising box when the mat-like seedling is grown by the seedling-raising box and the sheet member.

[0004]

The feature of the present invention resides in that the seedling raising device is constructed as follows. In other words, it is a rectangular bottomed box shape in plan view, and a seedling raising box with concave portions on the upper surfaces of both short edges of its outer edge, a bottom plate portion laid on the bottom of the seedling raising box, and one short edge of the seedling raising box. A vertical side portion along the inner surface of the vertical wall, and a sheet member having a grip portion that enters a concave portion on the upper surface of one short edge portion of the nursery box and projects laterally from the short edge portion, Configure a nursery tool.

[0005]

When configured as in the present invention, for example, FIG.
As shown in (b), when the sheet member 11 is put into the seedling raising box 1, the handle portion 14 of the sheet member 11 enters the concave portion 2a of the one short edge portion 2 of the seedling raising box 1, and the handle portion 14 is short. It is in a state of protruding laterally from the edge portion 2. This allows
The upper surface of the handle portion 14 does not project upward from other portions such as the long edge portion 3 of the seedling raising box 1. When a plurality of seedling raising boxes 1 in such a state are joined together, one handle 14 of the sheet member 11 protruding laterally from the short edge portion 2 of the seedling raising box 1 as shown in FIG. It enters into the concave portion 2a of the short edge portion 2 of the front or rear seedling raising box 1, and in this case as well, the handle portion 14 that has entered is another portion such as the long edge portion 3 of the front or rear seedling raising box 1. It does not project upward from the. Therefore, even if the seedling raising box 1 and the sheet member 11 are sent to the seeding device in the above state, the handle portion 14 of the sheet member 11 does not interfere with each operation in the seeding device and the seeding process is hindered. Will be done without.

After the seeding is performed and the seedlings are germinated as described above, when the handle portion 14 of the sheet member 11 is held by hand and pulled up, the sheet member 11 becomes the nursery box 1.
A mat-like seedling can be taken out of the nursery box 1 (see FIG. 4). In this case, since the handle portion 14 of the sheet member 11 projects from the short edge portion 2 of the nursery box 1, the handle portion 14 can be easily held by hand, and the sheet member 11 can be held in the longitudinal direction of the nursery box 1. Since the sheet member 11 is pulled up along the direction, the sheet member 11 can be easily pulled away from the seedling raising box 1.

[0007]

As described above, when mat-like seedlings are grown by the nursery box and sheet member, the mat-like seedlings can be easily taken out from the nursery box without using a scooping plate or the like. , The workability of raising seedlings was improved. And in the apparatus for raising seedlings (seedling raising box and sheet member) of the present invention, since the sheet member does not project unnecessarily, the sheet member is caught in the seeding device, which causes a problem that the seeding work is hindered. There is no.
