Abstract

PURPOSE:To readily perform a switching operation between a receiving state in the time of germination and afforestation and a lighting state, in the time of the hardening of the seedlings, by switchably constituting a raising seedling box-receiving state for holding seedling-receiving raising seedling boxes in a longitudinally superimposing state and a lighting state, for holding the boxes in a step state. CONSTITUTION:A bottom frame 17 and a ceiling frame 18 each having a plane square form are pivotally supported on four supports 19 in a mutually rotatable state around horizontal shaft axes to prepare a raising seedling frame, 1 having a parallel four- linking mechanism on a side view. A plurality of sowed raising seedling boxes 4 are held on the raising seedling frame 1, in an attitude superimposing the boxes 4 in plural stages, each having a prescribed interval to germinate the seeds and to green the germinated seedlings. When the seedlings are entered into a hardening process, the connection of supporters 20 disengageably connected between the supports 19 is canceled to release the linking state for inclining the raising seedling frame 1, and the respective raising seedling boxes 4 are held in an attitude, mutually superimposed in an approximately step state, thereby switching the raising seedling frame 1 into a lighting state where the upper side of each raising seedling box 4 is partially opened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seedling raising frame for growing mat seedlings to be planted by a rice transplanter.

C. Prior art] In the above-mentioned seedling raising frame, conventionally, for example,
As disclosed in Japanese Patent Application No. 35005, a retaining part is formed in one corner of the seedling box that houses the upper surface of the bed to rotatably engage with the support of the seedling growing frame, and a plurality of seedling boxes are attached to the support. There was a structure in which it was polymerized and held and supported.

[Problem to be solved by the invention]

To raise mat seedlings as described above, in general, seeds are placed on the bed in each seedling box, sown, and then stored in a seedling tray, and germination and greening are performed by controlling the temperature and humidity appropriately while blocking external light. At the same time, sufficient external light is applied during the curing process to encourage the growth of healthy seedlings.

Therefore, in the conventional structure described above, it is possible to easily change the storage state in which external light is blocked and the state in which external light is evenly applied to each area. This method has the disadvantage that the work of attaching and removing the box to the seedling-growing frame is troublesome, and the seedling-growing box requires special processing, making it difficult to transport it to the rice transplanter.

The present invention aims to eliminate the above-mentioned disadvantages through rational improvements.

[Means to solve the problem]

Characteristic configurations of the present invention include a storage state of the seedling raising box in which a plurality of seedling raising boxes containing seedlings for growing are held in a vertically stacked position with a predetermined interval, and a position in which the seedling raising boxes are stacked in a substantially step-like manner. The structure is such that the seedling raising box can be freely switched to a lighting state in which a part of the upper side of each seedling raising box is opened.

[For production]

When the seedling growing box is set to the stored state, the seedling growing boxes are vertically stacked, so that they can be stored in the seedling growing box in a compact form with a small width. Moreover, switching from the storage state to the daylighting state can be achieved by simply tilting the display in an oblique direction. Moreover, each seedling growing box only needs to be placed and supported, and there is no need for special processing, and existing structures can be used.

〔Effect of the invention〕

As a result, according to the present invention, it is possible to switch between the storage state during germination and greening and the lighting state during hardening with a simple operation, and yet the structure allows existing seedling growing boxes to be placed and supported. Therefore, the troublesome work of installing, removing, or transporting the seedling box can be eliminated.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 and FIG. 2 show a seedling-raising device (2) equipped with a seedling-raising frame (1) according to the present invention. This seedling raising device (2) is

It is configured to be placed and supported.

The seedling raising box (4) is filled with the floor above, and after seed rice is sown, the upper part of the box is covered with soil. The seedlings in this seedling raising box (4) are grown in the seedling raising device (2) and, after growing into mat-like seedlings, are subjected to rice planting work using a rice transplanter.

Figure 4 shows a riding rice transplanter. This rice transplanter has a drive-driven link mechanism (
A seedling planting device (7) is connected to the seedling planting device (7) via the device (6). On both the left and right sides of the seedling planting device (7), there are line markers (8) that can swing in and out to create guide grooves for adjacent rows on the mud surface as the machine moves. It is arranged.

As shown in FIGS. 5 and 6, the line marker (8) is aligned with the front and rear axis (P
l) It is supported by the frame (7) so as to be able to swing freely between the retracted state in an upright position and the operating state in which it protrudes sideways outward, and regardless of the raising and lowering of the seedling planting device (7), A locking mechanism (10) is provided to maintain the planting side in the stored state.

That is, the push-pull rod (11) is pivotally connected near the pivot point of the line marker (8), and the striped frame (12)
