Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a growing device according to the present invention. As shown in FIGS. 1 and 2, the growing device 1 is formed in a box frame shape by using a pipe made of a metal pipe or a synthetic resin pipe. (I.e., a shelf frame) 2 provided with casters 2a.

The seedling rack 3 on which seedling boxes (not shown) accommodating seedlings can be placed in a plurality of rows by connecting the vertical frames 20 at the four corners of the bench 2 up and down by a horizontal frame 21 and connecting them in multiple stages. Has formed. The bench 2 can be easily put in and out of a growth room (not shown) provided with an air conditioner and the like. The horizontal frames 21 and 21 arranged before and after each seedling shelf 3 are connected by a plurality of connecting rods 22 to form a floor structure. In the illustrated example, the connecting rods 22 are located at the center of the horizontal frame 21. A total of three, one at the left and right at predetermined intervals, are provided to enable the placement of the seedling box, and one at the center also serves as a mounting member for the reflector 5 described later.

Reference numeral 6 denotes a connecting rod 2 arranged at the center of the seedling rack 3.
2 is an illumination lamp suspended along the longitudinal direction below the lighting device 2. As shown in FIG. 3 and FIG. 4, the illumination lamp 6 has a mounting arm 23 (which is detachably fixed below a mounting portion 22 a provided on the connecting rod 22 by a mounting screw 22 b and formed in a U-shape in a side view. On the lower side of the bracket), socket portions 61 and 6 provided on a lamp base 62 containing a ballast.
A lamp unit 60 made of a tube rod-shaped fluorescent tube or the like is supported between the two.

As shown in FIG. 1, the illuminating lamp 6 has a predetermined distance between the center of the upper surface of the connecting rod 22 at the center and the lower surface of the reflecting plate 5 extended below the connecting rods 22 on both sides thereof. The lamp section 60 is provided upward with a reflection interval K formed at a distance. The lamp base 62 is formed in a box shape, and an electric device such as a chalk is provided inside the box.

In this embodiment, the connecting rod 22 constitutes a support member for the reflector 5 as one set of a total of three connecting rods, one at the center and two on both sides thereof. In the bench 2 using the connecting rod 22 of FIG.
The number of connecting rods 22 supporting the number becomes more than three, and accordingly, the shape of the reflecting plate 5 can be precisely adjusted so as to form an accurate curved surface. In this sense, the present invention is provided on condition that the reflecting plate 5 is supported using at least three connecting rods 22,
Naturally, the number may be more.

On the other hand, the reflecting plate 5 is formed by forming a rectangular plate made of an iron plate or a plastic plate and having a length of the connecting rod 22 in a downwardly curved shape in a sectional view, and having a central portion and both sides thereof. The corresponding connecting rod 22 is maintained in a downwardly curved shape via an appropriate number of attachments 5a. Although the mounting fixture 5a is a simple one whose length cannot be changed, a reflecting plate 5 adapted to the individual bench 2 is used.
In order to accurately form the curved shape of the above, it is preferable to use a material whose length can be changed.

In this embodiment, the reflection plate 5 is mounted directly on the connecting rod 22 arranged at the center.
An accurate reflection surface can be formed by adjusting the shape of the reflection plate 5 by placing a fixture or a spacer also in this portion. The reflecting plate 5 is arranged in parallel with the lamp section 60, and its curved surface reflects light emitted from the lamp section 60 composed of one fluorescent lamp located at the center as shown in FIG. The lower seedling shelf 3 is formed to have a curvature and a width that can be reflected substantially uniformly.

The breeding apparatus 1 configured as described above reflects the light beams emitted from one lamp unit 60 on the seedlings placed on each seedling shelf 3 with the reflecting plate 5 to illuminate the seedlings substantially uniformly. The breeding can be performed satisfactorily and at low cost. That is, since the illumination lamp 6 is provided with an appropriate reflection interval K between the lamp unit 60 and the central part of the reflector 5 with the lamp unit 60 facing upward, the light rays emitted from the lamp unit 60 are indicated by arrows in FIG. As described above, the light is reflected downward in a dispersed state on the curved surface of the reflection plate 5, and can be efficiently reflected widely over the entire width of the seedling shelf 3 below.

Further, in the central part of the reflecting plate 5, the lamp 6 has the lamp base 62 below the lamp part 60, and the lamp base 62 is arranged in a direction opposite to that of the conventional lamp. Without directly irradiating the seedlings with
It is possible to project light toward the upper reflector 5 while reflecting the light going downward by the lamp base 62 having a ballast built therein, reflect the light on the surface of the reflector 5 and irradiate the light downward.

Therefore, the fact that the area directly below the central portion of the reflector 5 on which the illuminating lamp 6 is installed is markedly illuminated is confirmed by the lamp unit 60.
This is prevented by a simple and inexpensive configuration using the lamp base 62 of FIG. The seedlings placed on the seedling shelf 3 can be satisfactorily grown by illuminating the seedlings almost uniformly while using one lamp unit 60. Further, since the growth apparatus 1 of the present invention has a substantially small amount of heat generation due to the above-described structure, the temperature of the atmosphere in the growth chamber into which the growth apparatus 1 is sent is not significantly increased, and the running cost of the air conditioner and the like is reduced. Etc. can also be reduced.

Further, since the wind circulating into the growing chamber can be formed from one side to the other side on the curved surface of the reflecting plate 5, an appropriate airflow can be formed, so that the seedling can be satisfactorily grown. There are advantages such as.

[0020]

As is apparent from the above description, according to the plant growing apparatus of the present invention, the lamp portion is provided at the center of the reflector formed on the downwardly curved surface so that the lamp base is on the lower side. The light source of the lamp part can be prevented from being directly irradiated on the seedlings placed on the seedling shelf, and the light ray of the lamp part can be substantially uniformly reflected by the reflector. In addition, seedlings can be satisfactorily grown with a single lamp while suppressing the temperature rise inside the growing apparatus. Further, the configuration of the growing device can be simplified, and the running cost can be reduced.
