  The present invention relates to a plant cultivation rack that can be easily grown using a container for plant cultivation.

  When plant cultivation is performed by three-dimensionally supporting a container for plant cultivation on a rack shelf, it is necessary to efficiently illuminate the plant planted in the container. That is, lighting fixtures must be incorporated in this type of plant cultivation rack. However, this type of conventionally known rack, for example, as described in Japanese Patent Application Laid-Open No. H10-228707, has a light beam on the upper side of the rack shelf. Arrange the lighting fixtures with the reflectors in an appropriate arrangement, or provide each of the lighting fixtures with a large light reflector common to a plurality of lighting fixtures without providing the light reflector, A lighting fixture was attached to the side.

JP 2008-245554 A

  In the conventional plant cultivation rack as described above, in which the lighting fixtures each provided with a light reflecting plate are used, a light reflecting plate is required for each of a large number of lighting fixtures, so that the equipment cost required for lighting increases. . In addition, the configuration using a large light reflector common to a plurality of lighting fixtures is effective in reducing the equipment cost required for lighting, but this large light reflector is also a light reflector provided in each lighting fixture. Since the horizontal light reflector is only enlarged, the upper side of the container for plant cultivation is arranged at a height that does not interfere with the plant cultivation space higher than the height of the cultivation plant at the time of harvest. The surroundings of the plant cultivation space are in a completely open state, and the degree of leakage of light from the lighting fixtures from the surroundings of the plant cultivation space to the outside of the rack is very large, and an efficient lighting effect cannot be obtained. .

  The present invention proposes a plant cultivation rack capable of solving the conventional problems as described above, and the plant cultivation rack according to the present invention according to claim 1 is an embodiment described later. The rack 23 is provided with a shelf 11 on which a plurality of cultivation containers 1 are placed so as to be freely put in and out in the depth direction in the frontage direction, and the surrounding means 23 whose inner surface is a light reflecting surface is the rack 23 described above. Arranged above the shelf 11, the enclosure means 23 is open only on the lower side covering the substantially upper half of the plant cultivation space necessary on the upper side of the container 1. A rectangular horizontal light reflecting plate 18 that can cover the light and surrounding vertical light reflecting plates 19 to 22 that hang from the four sides of the horizontal light reflecting plate 18. A light source (fluorescent tube 17a) is provided. Rutotomoni, the side of the vertical reflection plate 19 at least the container 1 is out is openably configuration.

  When carrying out the present invention, specifically, as described in claim 2, the shelf 11 is configured by arranging beam members 14 parallel to the frontage direction in parallel in the depth direction at appropriate intervals, and The luminaire 17 has its main body 17b attached to the lower side of the beam member 14, and the horizontal light reflector 18 of the surrounding means 23 is stretched under the main body 17b of the luminaire 17, Only 17 light sources (fluorescent tubes 17 a) can be arranged below the horizontal light reflector 18.

  Further, as described in claim 3, the shelf 11 protrudes from the container 1 supported by the shelf 11 to the side where the container 1 is put in and out and protrudes above the container support surface of the shelf 11. As described above, a guide roller 15 for supporting and guiding the container 1 to be taken in and out can be provided.

  According to the structure of this invention of Claim 1, the light beam from the light source of a lighting fixture covers the substantially upper half part of the plant cultivation space higher than the height of the cultivation plant at the time of the upper side of the container for cultivation. Since it is reflected by the light reflecting surface of the inner surface of the means, when there is no surrounding means, only a horizontal light reflecting plate that forms the ceiling part of the surrounding means (the periphery is slightly inclined downward) is used. Compared with the conventional configuration, the illuminance on the container can be greatly increased. Therefore, an efficient lighting effect can be obtained while reducing the equipment cost and power consumption required for the entire lighting means, and plants can be cultivated efficiently. Of course, the ventilation with respect to the plant cultivation space can be realized without any problems because the lower periphery of the enclosure means is open. Furthermore, when the container for cultivation is taken in and out of the rack, the vertical light reflecting plate of the enclosure means on the container entry / exit side can be opened, so that the container for cultivation is similar to the case without the enclosure means. Easy to put in and out.

  In addition, according to the structure of Claim 2, using a beam material parallel to the frontage direction which comprises a shelf, a lighting fixture (especially rod-shaped fluorescent lamp type lighting fixture) can be easily attached, The horizontal light reflecting plate of the enclosure means can be easily attached using the main body of the lighting fixture as a mounting seat. Furthermore, according to the configuration of the third aspect, the cultivation container can be taken in and out by the guide roller that can deposit the weight of the straw when the cultivation container is taken in and out and smoothly moves the container in and out. Can be done easily and safely.

A figure is a top view of the container for soil cultivation used for the rack which concerns on this invention, B figure is the longitudinal cross-sectional front view. It is a vertical side view of the same container for soil cultivation. It is a top view which shows the container for soil cultivation cultivation same as the above before the soil filling. It is a partially longitudinal front view which shows the principal part of the rack which concerns on this invention. It is a cross-sectional top view which shows a rack same as the above. It is a vertical front view which shows the water supply means integrated in the rack same as the above. It is a partially vertical side view which shows the principal part of a rack same as the above. It is an enlarged view of the A section of FIG.

  First, the soil cultivation container used for the book rack will be described with reference to FIGS. 1 to 3. The soil cultivation container 1 includes a container body 2 having a rectangular planar shape, and an inner side of the container body 2. The irrigation pipe 3 placed on the bottom surface 2a, the plant cultivation soil layer 4 made of the soil filled in the container body 2 from above the irrigation pipe 3, and the trial planted in the plant cultivation soil layer 4 It comprises a plurality of light reflecting sheets 5 that cover the surface of the soil layer 4 for plant cultivation around the plant seedling 5.

  As the container body 2, a synthetic resin container for storing goods or transporting can be used as it is, and the size is not particularly limited, but a plant cultivation environment using a rack as will be described later. In consideration of the case where the interior is configured indoors, a long side length: about 700 mm, a short side direction length: about 460 mm, a height: about 120 mm (height from the inner bottom surface 2a: about 112 mm) was adopted. As the irrigation pipe 3, for example, a water-permeable flexible pipe made of porous rubber and in which water oozes out from the entire surface can be used. The irrigation pipe 3 is disposed on the inner bottom surface 2 a of the container body 2. Next, it is bent and placed in an annular shape so as to be separated from the peripheral wall of the container body 2 by a substantially constant distance, and one end of the irrigation pipe 3 is guided to one corner of the container body 2 and bent upward. A water receiving end 3a projecting vertically upward from the container main body 2 is formed, and the other end opening located on the inner bottom surface 2a of the container main body 2 is closed by fitting and fixing the cap 3b. As the soil constituting the soil layer 4 for plant cultivation, for example, a soil known as a non-chemical environmental material for soil, such as “bentonite” coated on “peat moss”, which is a general soil improvement material, can be used. Such a soil was filled so that the set-up height from the inner bottom surface 2a of the container body 2 to the surface of the soil layer 4 for plant cultivation (a flat surface before forming a ridge as shown in the figure) was about 80 mm. . As the light reflecting sheet 5, for example, a light reflecting sheet made of ultrafine foamed polyethylene terephthalate can be used.

  In the illustrated example, a plurality of ridges 4a parallel to the container body short side direction are formed on the surface of the plant cultivation soil layer 4 at appropriate intervals in the container body long side direction, and each ridge 4a is appropriately arranged in the cocoon length direction. The seedlings 6 of cultivated plants (small leafy vegetables) are planted at intervals, and the width between the ridges 4a and the outside of the ridges 4a at both ends is a band that is long in the direction of the short side of the container body and is suitably narrower than the interval between the minimum ridges. A plurality of light reflecting sheets 5 cut into a band having a prescribed size are laid with the light reflecting surface facing up so as to cover the surface of the soil layer 4 for plant cultivation. Depending on the type of cultivated plant, the number of juts 4a formed in parallel decreases and the spacing between the coffins 4a widens. Therefore, when only the light reflecting sheet 5 having the specified size is used, 2 between the coffins 4a. The light reflecting sheets 5 can be laid so as to partially overlap each other. Of course, in actual planting, it is also possible to use the light reflecting sheet 5 cut according to the interval between the ridges 4a at that time. In addition, what is necessary is just to form the basket 4a according to a cultivation plant, and when the basket 4a is unnecessary, what is necessary is just to finish the surface of the soil layer 4 for plant cultivation flat.

  Next, the cultivation rack of the present invention that supports the above-described soil cultivation container 1 will be described with reference to FIGS. 4 to 8. The figure shows only the intermediate two-stage shelf 11 of the rack 10. Even in the case of a rack having more than one shelf, the configuration of each shelf is the same as that shown in the figure. The rack 10 includes support members 12 whose lower ends and upper ends are connected to each other by connecting frames at four corners thereof, and the shelves 11 of each step are installed between a pair of support members 12 in the rack depth direction. The shelf 11 shown in the figure is supported by a pair of left and right shelf holders 13 in which a plurality (four in the illustrated example) of beam members 14 parallel to the rack opening direction are arranged in parallel at appropriate intervals in the rack depth direction. Thus, each beam member 14 is supported by a beam member fitting support portion formed on the shelf support 13 at both ends thereof. Of course, the shelf 11 is not limited to the one having the above-described configuration, and the entire surface is constituted by a single plate material, the one constituted by a plurality of strip-like plates before and after the rack depth direction, and parallel to the rack frontage direction. Various conventionally well-known shelves, such as a structure in which a sub beam material parallel to the rack depth direction is installed between the pair of front and rear beam materials at appropriate intervals in the rack front-end direction, can be used.

  On each shelf 11, a plurality of (three in the illustrated example) parallel arrangements of the containers 1 for soil cultivation in the above-described configuration are arranged in the rack front direction with the container body long side direction being parallel to the rack depth direction. Supported. At this time, the rack 10 is configured in such a size that both the front and rear ends in the long side direction of each container main body 2 can be accommodated between the pair of column members 12 before and after the rack depth direction when the rack 10 is viewed from the side. Of the plurality of beam members 14 to be configured, the beam members 14 at the front and rear ends in the depth direction are configured to enter slightly inside the front and rear ends in the long side direction of the container 1 to be supported. Thus, the shelf 11 of each stage is provided with a guide roller 15 on the front side (side where the container 1 is put in and out) and a stopper 16 for preventing container drop on the back side. The guide roller 15 is a roller disposed between the pair of left and right support members 12 on the front side of the rack 10 and oriented in parallel to the rack front direction, and the bearing members at both ends thereof are attached to the pair of left and right shelf supports 13. Yes. Thus, the guide roller 15 protrudes slightly forward from the front end of the container 1 supported by the shelf 11 and slightly above the container support height of the shelf 11 (the upper surface height of the beam member 14). It projects so as to prevent the container body 2 from sliding out to the front side. The container drop prevention stopper 16 is composed of a rod-shaped member disposed between the pair of left and right support columns 12 on the rear side of the rack 10 and oriented parallel to the rack front direction, and is positioned at a position higher than the container support height of the shelf 11. Both ends are attached to a pair of left and right shelf supports 13.

  A lighting fixture 17 is attached above the soil cultivation container 1 supported by the shelf 11 of each stage using the ceiling frame of the shelf 11 or the rack 10 positioned directly above the container 1 for soil cultivation. It has been. The lighting fixture 17 may be a rod-like or annular fluorescent lamp, a bulb-type fluorescent lamp, or any other one, but a fluorescent lighting fixture specialized for plant cultivation is particularly desirable. In this illustrated example, a rod-like fluorescent lamp for plant cultivation is used as the lighting fixture 17, and a plurality of lighting fixtures 17 arranged in parallel in the rack depth direction are arranged such that the fluorescent tubes 17 a are parallel to the rack frontage direction and the lower side. It is attached to the lower side of the shelf 11 (or the ceiling frame) so as to illuminate the cultivated plant planted in the soil cultivation container 1. Specifically, the lighting fixture 17 attached to the lower side of the shelf 11 having the above-described configuration has the main body 17b of the lighting fixture 17 attached to the lower side of the beam member 14 constituting the shelf 11.

  A horizontal light reflector 18 is stretched so as to pass between the main body 17b of each lighting fixture 17 and the fluorescent tube 17a attached as described above. The horizontal light reflecting plate 18 has a width in the rack depth direction that is substantially the same as a width in the depth direction of the rack 10 (interval between the outer surfaces of the pair of front and rear support members 12). The distance between the inner surfaces of the pair of left and right strut members 12 in the frontage direction 10 is substantially the same, and is attached to the main body 17b of each lighting fixture 17 with the light reflecting surface facing downward. Further, a front side light reflecting plate 19, a back side light reflecting plate 20, and left and right side light reflecting plates 21, 22 that hang vertically are provided on both the front and rear sides and the left and right sides of the horizontal light reflector 18. The plant cultivation space on the upper side of the container 1 that is connected in a direction in which the surfaces face each other and supported by each shelf 11, that is, the upper half of the plant cultivation space that is higher than the height of the cultivation plant at the time of harvesting, The light reflecting plates 18 to 22 have a structure in which only the lower side is opened and the entire inner surface is covered with a surrounding means 23 that is a light reflecting surface. Therefore, the fluorescent tubes 17a of all the lighting fixtures 17 are arranged directly below the horizontal light reflecting plate 18 inside the enclosure means 23.

  Of the light reflectors constituting the enclosure means 23, at least the front light reflector 19 for taking in and out the soil cultivation container 1 is hinged or a cloth instead of the front side of the upper horizontal light reflector 18. It is attached so as to be able to swing up and down through a connecting member (such as a gummed tape). In addition, a blower fan 24 is disposed at one end of the space surrounded by the enclosure means 23 in the rack front-end direction, for example, inside the light reflection plate 21, and the light reflection plate 22 on the opposite side includes the portion shown in FIG. As shown in FIG. 8, a required number of horizontally elongated slit-like air circulation ports 25 each having a flap 25a extending obliquely downward inward from the upper side are provided. The flap 25a may be extended obliquely downward to the outside, or the flap 25a may be omitted, contrary to the illustration. Further, when the flap 25a is extended obliquely downward inward as shown in the drawing, the amount of light reflected to the inner side of the light reflecting plate 22 due to the presence of the air circulation port 25 is larger than in the case of extending obliquely downward outward. Decrease can be suppressed.

  Further, as shown in FIGS. 6 and 7, the rack 10 is provided with an independent water supply means 26 for each shelf 11. Each water supply means 26 includes a water supply pipe 27 installed horizontally below the horizontal light reflecting plate 18 of the surrounding means 23 provided above the shelf 11 of each stage and in the vicinity of the front side, A branch pipe 28 that branches downward at a right angle from a position corresponding to each soil cultivation container 1, a stop cock 29 connected to the branch pipe 28, one end is detachably connected to each stop cock 29 and others The flow rate is adjusted to one end of the water supply pipe 27 and the flexible pipe 30 detachably connected to the water receiving end 3 a of the irrigation pipe 3 in each soil cultivation container 1 whose end is located below the stop cock 29. It consists of a water supply tank 32 connected via a valve 31. The other end of the water supply pipe 27 is closed by a cap 33.

  The water supply tank 32 is attached to the outside of the rack 10 in the front end direction at a position higher than the water supply pipe 27. However, the water supply tank 32 may be configured to be disconnected from the water supply pipe 27 when water is replenished. Open for use (a lid may be provided if necessary) so that when the water level in the water supply tank 32 falls below a certain level, water can be refilled manually by a hose connected to the water supply. Can be configured. Of course, in the case of a large-scale facility in which a large number of racks 10 having the above-described configuration are installed, a water level detection sensor is attached to each water supply tank 32 and a water supply pipe connected to the water supply for each water supply tank 32. Is connected via an automatic opening / closing valve, and when the water level detection sensor detects that the water level in the water supply tank 32 has fallen below the lower limit level, the water supply pipe connected to the water supply tank 32 is automatically opened and closed. All the water tanks are configured to close the automatic opening / closing valve when the valve is opened and the water level detection sensor detects that the water level in the water tank 32 has reached the upper limit level as a result of water supply. It is also possible to configure so that water supply to 32 is performed fully automatically.

  Next, a method of using the soil cultivation apparatus configured as described above will be described. The soil cultivation container 1 that has been completed by planting the seedlings 6 of the cultivation plant in the manner described above is used for each stage of the rack 10. A predetermined number is placed in parallel on the shelf 11 so that the long side direction of the container body is parallel to the rack depth direction. At this time, the front-side light reflecting plate 19 of the surrounding means 23 is opened to the upper front. A means for holding the front side light reflecting plate 19 in an open state, for example, a tip hook portion of a hanging tool such as a chain or a string is provided in a locked hole provided near the lower side of the front side light reflecting plate 19. It is desirable to use simple holding means that can be engaged together.

  On the other hand, the stop cocks 29 of the water supply means 26 provided on each shelf 11 of the rack 10 are closed, and the water supply tank 32 is replenished with a required amount of water. In this state, the flexible pipe that hangs down from the water supply pipe 27 of the water supply means 26 provided in the shelf 11 on which the soil cultivation container 1 is placed at the water receiving end 3a of the irrigation pipe 3 in each soil cultivation container 1 Connect the tip of 30 and open the stop cock 29. As a result, water is automatically supplied from the water supply tank 32 to the irrigation pipe 3 in the soil cultivation container 1, and the irrigation pipe is generated by the position head energy of the amount of water in the water supply path from the water supply tank 32 to the irrigation pipe 3. As described above, water spreads from the periphery of the irrigation pipe 3 to the whole plant cultivation soil layer 4 by capillary action or the like. The whole can be maintained in a moist state with the required humidity.

  At this time, the surface of the plant cultivation soil layer 4 is covered with the light reflecting sheet 5 except for the periphery of the roots of the seedlings 6, so that the moisture transpiration from the surface of the plant cultivation soil layer 4 is extremely small. Therefore, the irrigation pipe 3 is used so that the humidity of the plant cultivation soil layer 4 gradually increases with time, moisture does not stay at the bottom of the plant cultivation soil layer 4, and the retention amount of the moisture does not gradually increase. The amount of water exudation per unit time from the water supply tank 32 can be set by the flow rate adjustment valve 31 on the side of the water supply tank 32. Basically, the amount of water in the water supply channel from the irrigation pipe 3 depends on the position head energy. Since the amount of moisture exudation per unit time is determined, by setting the position head energy in advance according to the capacity of the water supply tank 32 and the height relative to the water supply pipe 27, the plant cultivation soil layer 4 becomes excessively humid as described above. Can be prevented.

  While operating the water supply means 26 as mentioned above, it supplies with electricity to the lighting fixture 17 with which each shelf 11 is equipped, and the fluorescent tube 17a is lighted. As a result, the cultivated plant space on the lower side of the enclosing means 23 is not only from the direct light from the fluorescent tube 17a but also from the light reflecting surface (the light reflecting surfaces of the light reflecting plates 18 to 22) on the entire inner surface of the enclosing means 23. Illuminated by the reflected light beam and the reflected light beam in the sky on the light reflecting sheet 5 covering the soil layer 4 for plant cultivation. That is, the entire periphery of the cultivated plant seedling 6 including the leaf back side of the cultivated plant seedling 6 can be illuminated with a necessary illuminance.

  In the inner space of the enclosure means 23, the inner space is open only on the lower side, and a large number of fluorescent tubes 17a in the vicinity of the ceiling of the inner space are turned on. Temperature rise is considered. However, by energizing the blower fan 24 and blowing it with a very weak wind force from the end of the rack opening direction (longitudinal direction) inside the enclosure means 23 slightly obliquely upward, it is opposite to the blower fan 24. In connection with the presence of the air circulation port 25, a very weak air flow in the longitudinal direction can be generated in the inner space of the enclosure means 23, and this air flow causes air to flow between the inner space and the outside of the enclosure means 23. Can be generated. As a result, it is possible to prevent high temperature air from staying in the inner space of the enclosure means 23 and adversely affect the seedling 6 of the lower cultivated plant, and the atmosphere around the cultivated plant seedling 6 is maintained. It is possible to prevent the stationary. Of course, since the periphery of the seedling 6 of the cultivated plant between the enclosure means 23 and the soil cultivation container 1 is open, the atmosphere adjusted by the air conditioner in the plant cultivation room where the rack 10 is installed is Since air flows into the plant cultivation space on the upper side of the soil cultivation container 1 due to the influence of the air flow generated in the inner space of the enclosure means 23, the air around the seedling 6 of the cultivation plant also remains stationary. There is no.

  As described above, the interior of the plant cultivation soil layer 4 is always kept in a moist state at an appropriate humidity according to the properties of the soil constituting the plant cultivation soil layer 4 and the type and degree of growth of the cultivated plant. Set the lighting time and illuminance per day, and also set the energizing time and wind power per day of the blower fan 24, and planted in the soil layer 4 for plant cultivation of each soil cultivation container 1 By growing the plant seedling 6, it is possible to grow the seedling 6 of the cultivated plant well during the required period and reach the harvest season.

  When harvesting a cultivated plant, the stop cock 29 of the water supply means 26 connected to the irrigation pipe 3 of the container 1 for soil cultivation is targeted, and the flexible pipe 30 is received by the irrigation pipe 3. The soil-cultivating container 1 to be harvested is pulled out from the top of the shelf 11 with the front light reflector 19 of the enclosure means 23 lifted up and opened from the water end 3a. Since the guide roller 15 is slightly high, it is transferred onto the guide roller 15 so as to lift the front side of the soil cultivation container 1 to be pulled out. By pulling out the soil cultivation container 1 in this state, the soil cultivation container 1 to be harvested can be taken out from the shelf 11 lightly and smoothly using the rolling of the guide roller 15. Further, among the beam members 14 constituting the shelf 11, the beam member 14 on the front side recedes from the front side of the horizontal light reflecting plate 18 of the enclosure means 23 included in the shelf 11 immediately below, but this enclosure means. The guide roller 15 is disposed directly above the front side of the horizontal light reflector 18 of the horizontal light reflecting plate 18, and the soil cultivation container 1 to be taken in and out of the shelf 11 includes the enclosure means 23 provided in the shelf 11 directly below. The guide roller 15 can prevent the horizontal light reflector 18 from colliding with the front side.

  In the above embodiment, since the water stop cock 29 is provided in the branch pipe 28 branched from the water supply pipe 27, the flexible pipe 30 is used for irrigation even when the water stop cock 29 is switched to the water stop state. When the pipe 3 is removed from the water receiving end 3a, the water in the flexible pipe 30 flows out. The same is true even if the flexible pipe 30 is removed from the stop cock 29 side. Therefore, on the premise that the flexible pipe 30 is removed from the water receiving end 3 a of the irrigation pipe 3, a stop cock 29 is provided at the tip of the flexible pipe 30 connected to the water receiving end 3 a of the irrigation pipe 3. It is desirable to have it. The stop cock 29 may be of a type that is manually operated to stop water. However, when the stop cock 29 is provided at the tip of the branch pipe 28 and when the stop cock 29 is provided at the tip of the flexible pipe 30. In any case, as a means for detachably connecting the water stop cock 29 and the flexible pipe 30 or the flexible pipe 30 and the water receiving end 3a of the irrigation pipe 3, one of the one-touch couplers for connecting the water distribution hose (plug) Or a socket), which uses a one-touch coupler with a built-in water stop valve that has a built-in water shut-off valve that automatically shuts off when the one-touch coupler is removed. It is most desirable to connect the branch pipe 28 and the flexible pipe 30 or connect the flexible pipe 30 and the water receiving end 3a of the irrigation pipe 3 with the built-in water stop valve on the flexible pipe 30 side. It is an embodiment.

  The plant cultivation rack of the present invention uses a plant cultivation container such as a soil cultivation container filled with soil for plant cultivation, and is used as a relatively large plant in a room, not in the open ground, especially in a relatively large plant. It can be effectively used as a means to grow small leafy vegetables in a short cycle.
