Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method of irradiating light onto a medium used for artificial cultivation of mushrooms, early growth of plants, cultivation of bacteria, and other objects to be irradiated. The present invention relates to a light irradiation device used therefor.

(Prior Art) When cultivating bacteria or cultivating plants in a culture medium, conventionally, containers of culture medium B are arranged on a fixed shelf A as shown in Fig. 16.
The containerized culture medium B was illuminated with light C such as an electric light or fluorescent light from above shelf A.

(Problems with the prior art) In the conventional light irradiation method, the culture medium B arranged on the lower shelf of the fixed shelf A is replaced by the culture medium I on the upper shelf! ! H tends to be shaded, and even if medium B is arranged in the same row, some rows tend to be shaded. For this reason, there was a problem in that the growth of cultured bacteria and cultivated plants became uneven.

To solve this problem, widen the space between the media 8,
You can widen the gap between the upper and lower shelves or install a light source on the side of shelf A, but doing this will require a large area to line up the same number of culture media, and the number of light sources will also increase. If there are too many, it is uneconomical. Moreover, even with this method, there is a problem that light does not necessarily hit all the culture media uniformly.

(Objective of the Invention) The object of the present invention is to devise ways of arranging culture media and irradiating light so that light can be uniformly irradiated on all rows of culture media in all stages, and the space above can be used effectively. It is to make it.

(Means for Solving the Problems) The light irradiation method described in claim 1 of the present invention is a method for applying light to a medium used for culturing bacteria, artificially cultivating mushrooms, growing plants, etc. As shown in FIGS. 1 and 2, the irradiation objects 1 are arranged in a rectangular row on the shelf 2 and stacked in a desired number of stages.
Two or more stacked shelves 2 are arranged so that the corners 4 face each other as shown in FIG. The object 1 to be irradiated is irradiated from inside and outside by a light scattering body 6 installed as shown in FIGS.

The light irradiation device according to claim 2 of the present invention irradiates an irradiated object 1 such as a medium used for culturing bacteria, artificially cultivating mushrooms, growing plants, etc. as shown in FIG. Two or more shelves 2 on which objects 1 to be irradiated are arranged in a row in a rectangular shape and stacked in a desired number of stages, and the objects 1 to be irradiated are arranged so that the corners 4 face each other as shown in FIG. Inner space 3 and shelf 2 surrounded by
As shown in FIGS. 3 and 4, a light scattering body 6 is installed on the outside of the light scattering body 6, and the light scattering body 6 is a long light transmission body as shown in FIGS. 9 to 15. Light scattering portions 7 are formed at appropriate locations in the longitudinal direction of the light transmitting body to scatter the light transmitted within the light transmitting body to the outside.

(Operation of the invention) When light is transmitted from one end 6a in the longitudinal direction of the light scattering body 6 arranged as shown in FIGS. 3 and 4, a part of the light transmitted inside the light scattering body 6 is light scattered. The light is scattered from a light scattering part 7 formed on the outer periphery of the body 6, and the scattered light uniformly irradiates the surrounding objects 1 arranged on the shelf 2.

In this case, if a shelf 2 that is rotatable at a predetermined position and has a moat that can be moved in a desired direction is used, the shelves 2a and 2b arranged at the positions indicated by the solid line at the opening in Figure 7 can be replaced by the chain line in the same figure. It can be rotated to the position shown by , and in this way a passage 20 is formed between the adjacent shelves 2a and 2b.

(Example) In the present invention, as a medium, for example, a mixture of peat moss, sawdust, and rice moss, or a combination of these alone, or vermiculite or soil suitable for growing plants, culturing bacteria, artificially cultivating mushrooms, etc. use something These mediums are placed in a translucent container 30 as shown in FIGS. 17 and 18, and bacteria are planted and cultured in the medium, or seeds are sown to grow plants.

When putting the culture medium into the container 30, place a net or a bottom plate 35 with holes in the container 30, and put water 36 under the bottom plate 35.
and put the culture medium on the bottom plate 35.

The translucent container 30 is made of, for example, transparent plastic. Although the container 30 in FIGS. 17 and 18 is circular, the shape may be other than circular, for example, it may be polygonal. The dimensions of the container 30 may be selected as appropriate;
When used for cultivating bacteria, growing plants, or artificially cultivating mushrooms, a container 30 with a diameter of 12 cm and a height of 15 cm, for example, is easy to use.
A water container 32 is formed by protruding downward, and a ventilation hole 33 through which carbon dioxide gas passes is formed in the upper part of the peripheral wall.

The container 30 shown in FIG. 18 has a bottom outer peripheral portion 34 projecting downward to form a water container 32. As shown in FIG.

When arranging the containers 30 containing the culture medium on the shelf 2, cover the tops of the containers 30 with lids 37 and stack them in several stages on top of the lids 37, as shown in FIG. The number of layers to be stacked is selected as appropriate, but for example, if containers 30 each having a length of 15 cm are stacked in 12 layers, the total height will be about 180 cm, making it easy to handle, and the entire container will be uniformly irradiated with light. In this case, it will be more stable if you insert a partition such as a transparent plate, net, or perforated plate between every four pieces.

Further, on each stage of the shelf 2, for example, twelve containers 30 are arranged in a row around the periphery in a rectangular shape as shown in FIG. 1, thereby forming an inner space 3 inside the container rA30. container 30
When arranging containers 30, the distance between adjacent containers 30 is set to 6c, for example.
If m, the horizontal dimension of the shelf 2 will be about 70 cm, making it easier to handle.

The shelf 2 may be of any type as long as it can store or line up the objects 1 to be irradiated, but it is preferable that the shelf 2 be structured so that the object 1 to be irradiated is not shaded as much as possible when irradiated with light. As shown in Fig. 2, four pillars 50 with casters (not shown) at the lower ends are arranged, and connected between them by connecting bodies 51 such as round bars or round pipes, and a net is installed at appropriate intervals in the vertical direction. Or use a plate with a partition 52 such as a perforated plate.

When the shelf 2 is rotated, the shelf 2 rotates at that position. Therefore, the operator can take stored items in and out of the surrounding shelves 2 all around while staying at point B in FIG. 7, for example.

In addition, in FIG. 5, the eccentric rotating ring 27 is set in the fixing hole 24 of the bearing 9128 so as to be rotatable, and the central rotating shaft 25
is removed from the fixing hole 29 of the bearing board 28, and in this state, when the shelf 2a in FIG. Rotate from the solid line position of the opening in Figure 7 to the chain line position, 112a,
A gap wA (passage) 20 is formed between 2b. In this way, the worker who was working at point A in FIG. 7A can move through the first passage 20 to point B, where he can take out and put things into and out of the shelf 2C12d.

In this case, the eccentric position of the eccentric rotating shaft 27 is set to 0.6 a to the right and l/4 a to the left from point R as shown in Fig. 6A, and the angle is 45 degrees clockwise when looking at the shelf 2 from above. If you rotate it, the shelf 2 will be in the position of the opening in Figure 6, and at that time, the side PS will be in the position of S.
comes, so the passage on the left side of shelf 2 widens to the right by 0.4a.

As shown in FIG. 8, when the rotating shelf 2 of the present invention is rotated around a central rotating ring 25 formed on the bottom 26, it rotates at that position, and the central rotating shaft 3 is rotated as shown in the figure. When moved in the direction of arrow Y, it may be moved in the same direction.
