Description
本発明は、植物育成装置に関し、特に根菜類やイモ類や薬草類等の植物を育成する植物育成装置に関するものである。 The present invention relates to a plant growing device, and more particularly to a plant growing device for growing plants such as root vegetables, potatoes and medicinal herbs.
植物育成装置としては、特許文献１に示すように、上下方向に複数設けられた植物育成槽へ植物の育成に必要な養分を含む養液を随時供給するように構成された水耕栽培装置が知られている。 As a plant growing apparatus, as shown in Patent Document 1, a hydroponic cultivation apparatus configured to supply a nutrient solution containing nutrients necessary for growing a plant to a plurality of plant growing tanks provided in the vertical direction as needed. Are known.
ところで、根菜類やイモ類や薬草類等の植物は、これらの植物の根が養液の中に浸かった状態が続くと、根が腐ってしまい、育成させることができない。 By the way, plants such as root vegetables, potatoes and medicinal herbs cannot be grown if the roots of these plants continue to be immersed in the nutrient solution and the roots decay.
根を腐らせない方法として、噴霧式養液栽培方法もあるが、この方法では、例えば根菜類等の植物は、育成しても肥大化せずに毛根状態となり、本来の成長した姿にならない。 There is also a spray-type hydroponics method as a method that does not rot the roots, but in this method, for example, plants such as root vegetables do not become enlarged even when grown and become a hairy root state, and do not become the original grown form .
そこで、根菜類等を育成する植物育成装置として、植物育成槽に多数のスポンジを敷き詰めて団粒構造を形成し、この植物育成槽へ養液を供給するとともに植物育成槽内の水位を調整できるように構成されたものがある。このような構成によれば、植物育成槽内の水位を上げてスポンジに養液を浸み込ませ、その後、水位を下げることで、スポンジに浸み込んだ養液中の水分とスポンジの周囲の空気とによって、根菜類等の育成に適した育成環境を形成することができる。 Therefore, as a plant growing device for growing root vegetables and the like, a large number of sponges are spread over the plant growing tank to form a nodule structure, and a nutrient solution can be supplied to the plant growing tank and the water level in the plant growing tank can be adjusted. There is something configured as follows. According to such a configuration, by raising the water level in the plant growth tank and soaking the nutrient solution into the sponge, and then lowering the water level, the moisture in the nutrient solution soaked in the sponge and the surroundings of the sponge With this air, it is possible to form a growing environment suitable for growing root vegetables and the like.
しかしながら、上述した構成では、スポンジに形成されている空隙が微細であり、養液がすぐにスポンジに浸み込むわけではないので、植物育成槽内の水位を上げてから養液がスポンジに浸み込むまで待つ必要があり、水位を上げてから下げるまでにかかる時間が長くなるという問題がある。さらに、植物育成槽の上面が開口している場合は、水位の上昇により、スポンジが浮き上がって溢れ出る恐れがあるので、前記開口にパネル等を載置してスポンジが溢れ出すのを防ぎながら、水位をゆっくり上げていかなければならず、水位の調整にかかる時間がより長くなる。 However, in the above-described configuration, the gap formed in the sponge is fine, and the nutrient solution does not immediately soak into the sponge, so the nutrient solution is soaked in the sponge after the water level in the plant growth tank is raised. There is a problem in that it takes a long time to wait until the water level is lowered after the water level is raised. In addition, if the upper surface of the plant growing tank is open, there is a risk that the sponge will rise and overflow due to the rise in the water level, so it is possible to prevent the sponge from overflowing by placing a panel etc. The water level must be raised slowly, and the time taken to adjust the water level becomes longer.
そこで本発明は、上記問題点を解決すべくなされたものであって、植物育成槽内の水位を調整して根菜類等の植物の育成に適した育成環境を形成しながらも、水位の調整にかかる時間を短くすることをその主たる課題とするものである。 Therefore, the present invention has been made to solve the above-mentioned problems, and adjusting the water level while adjusting the water level in the plant growing tank to form a growing environment suitable for growing plants such as root vegetables. The main problem is to shorten the time required for the process.
すなわち本発明に係る植物育成装置は、養液が間欠的に供給される植物育成槽と、前記植物育成槽内に敷かれた培地と、前記養液の供給に伴って前記植物育成槽内の水位が上がり、前記培地が前記養液に浸ると、その後、前記養液を排出して前記水位を下げる水位調整機構とを具備し、前記培地が、一部に開口を有し、その開口を介して前記養液が内部空間に出入り可能に構成されている多数の中空体から形成されており、前記中空体が、管状をなし、一端が開口するとともに他端が閉塞していることを特徴とするものである。
That is, the plant growing apparatus according to the present invention includes a plant growing tank to which a nutrient solution is intermittently supplied, a medium laid in the plant growing tank, and the plant growing tank with the feeding of the nutrient solution. When the water level rises and the medium is immersed in the nutrient solution, the medium is equipped with a water level adjusting mechanism that discharges the nutrient solution and lowers the water level. The nutrient solution is formed from a large number of hollow bodies configured to be able to enter and leave the internal space, and the hollow body is tubular and has one end opened and the other end closed. It is what.
このような植物育成装置であれば、培地が養液に浸った後、水位調整機構が養液を排出して植物育成槽内の水位を下げると、中空体の内部空間に養液が残留するので、この養液中の水分と中空体の内部空間や周囲の空気とによって、根菜類等の植物の育成に適した育成環境を形成することができる。
そのうえ、培地を養液に浸す際は、植物育成槽に供給された養液がすぐに中空体の内部空間に流れ込むので、植物育成槽内の水位を速やかに上げることができ、養液を排出する際は、養液がすぐに内部空間から流れ出るので、水位を速やかに下げることができ、上述した育成環境を形成するための水位調整にかかる時間を従来より短くすることができる。
さらには、植物育成槽に供給された養液がすぐに中空体の内部空間に流れ込むので、中空体は、スポンジ等に比べて浮き上がりにくくなり、従来にように、スポンジ等の浮き上がりを防ぐパネル等を不要とすることができる。
With such a plant growing device, after the medium is immersed in the nutrient solution, when the water level adjusting mechanism discharges the nutrient solution to lower the water level in the plant growing tank, the nutrient solution remains in the internal space of the hollow body. Therefore, a growth environment suitable for growing plants such as root vegetables can be formed by the moisture in the nutrient solution, the internal space of the hollow body, and the surrounding air.
In addition, when the medium is immersed in the nutrient solution, the nutrient solution supplied to the plant growing tank immediately flows into the internal space of the hollow body, so that the water level in the plant growing tank can be quickly raised, and the nutrient solution is discharged. When doing so, the nutrient solution immediately flows out from the internal space, so that the water level can be lowered quickly, and the time required for the water level adjustment for forming the above-described growth environment can be made shorter than before.
Furthermore, since the nutrient solution supplied to the plant growing tank immediately flows into the internal space of the hollow body, the hollow body is less likely to float than a sponge or the like, and a panel that prevents the sponge or the like from floating as in the past. Can be made unnecessary.
植物育成槽内の水位をより速やかに上げる又は下げるようにするためには、前記中空体が、管状をなし、一端及び他端が開口していることを特徴とするものが好ましい。 In order to raise or lower the water level in the plant growing tank more quickly, it is preferable that the hollow body has a tubular shape and is open at one end and the other end.
前記中空体が、管状をなし、一端が開口するとともに他端が閉塞しているものが好ましい。
これならば、内部空間に養液が溜まりやすくなり、その養液に向かって植物の根が伸びるので、植物の育成を促進させることができる。
It is preferable that the hollow body has a tubular shape, one end is open and the other end is closed.
If it is this, since it will become easy to accumulate a nutrient solution in internal space and the root of a plant will extend toward the nutrient solution, the growth of a plant can be promoted.
水位調整機構としては、サイフォンを用いて前記水位を調整するものであって、前記植物育成槽内に位置する前記サイフォンの一端開口から前記養液が前記サイフォンに流入し、前記植物育成槽の外に位置する前記サイフォンの他端開口から前記養液が流出するように構成されており、前記水位の最高到達高さが、前記サイフォンの頂部の位置する高さに設定されており、前記水位の最低到達高さが、前記一端開口の位置する高さに設定されているものが挙げられる。
これならば、装置を大掛かりにすることなく、植物育成槽内の水位を容易に調整することができる。
As the water level adjusting mechanism, the water level is adjusted using a siphon, and the nutrient solution flows into the siphon from one end opening of the siphon located in the plant growing tank, and the outside of the plant growing tank The nourishing liquid flows out from the other end opening of the siphon located at the top of the siphon, and the maximum reached height of the water level is set to the height at which the top of the siphon is located. The minimum reachable height is set to the height at which the one end opening is located.
If it is this, the water level in a plant growth tank can be adjusted easily, without enlarging an apparatus.
植物の種類や植物の成長に応じて、水位の最高到達高さ位及び最低到達高さを所望の高さに設定できるようにするためには、前記サイフォンが、軸方向に伸縮可能な蛇腹形状をなしており、前記一端開口及び前記頂部の位置する高さを変更可能に構成されていることが望ましい。 In order to be able to set the maximum reachable height and the minimum reachable height of the water level to the desired height according to the type of plant and the growth of the plant, the siphon has a bellows shape that can be expanded and contracted in the axial direction. It is desirable that the height at which the one-end opening and the top portion are positioned can be changed.

前記水位調整機構が、前記植物育成槽それぞれに設けられており、前記植物育成槽内の前記養液を排出するとともに、その養液を当該植物育成槽の下方に位置する植物育成槽に供給するものが挙げられる。
このように構成することで、最上部に位置する植物育成槽内に養液を所定の量だけ供給すれば、養液が上方の植物育成槽から下方の植物育成槽へ順次流れていくので、各植物育成槽それぞれに対して個別に養液を供給する場合に比べ、必要な養液全体の量を少なくすることができる。
As a specific aspect of the present invention, a plurality of the plant growing tanks are arranged in the vertical direction,
The water level adjusting mechanism is provided in each of the plant growing tanks, and discharges the nutrient solution in the plant growing tank and supplies the nutrient solution to a plant growing tank located below the plant growing tank. Things.
By configuring in this way, if a predetermined amount of nutrient solution is supplied into the plant growing tank located at the top, the nutrient solution flows sequentially from the upper plant growing tank to the lower plant growing tank, Compared to the case where the nutrient solution is individually supplied to each plant growing tank, the total amount of the nutrient solution required can be reduced.
本発明の効果がより顕著になる実施態様としては、前記植物が、根菜類、イモ類、又は薬草類であるものが挙げられる。 As an embodiment in which the effect of the present invention becomes more prominent, the plant is a root vegetable, a potato, or a herb.

And a pump 22 for pumping the nutrient solution. The pipe L1 is provided with a check valve 23 for preventing the nutrient solution from flowing back from the plant growing tank 10 to the nutrient solution storage tank 21.
より詳細には、この養液供給機構２０は、図示しないタイマーを用いて、所定時間になるとポンプ２２が作動して所定量の養液が植物育成槽１０へ圧送されるように構成されている。ポンプ２２が作動するタイミングは前記タイマーで設定することができ、例えば、植物Ｖの発芽時期には３時間に１度、開花時期には３日に１度、収穫時期には１週間に１度となるように設定してある。
なお、これらのタイミングは、植物Ｖの種類に応じて設定を変更することができる。
More specifically, the nutrient solution supply mechanism 20 is configured such that a predetermined amount of nutrient solution is pumped to the plant growing tank 10 by operating a pump 22 at a predetermined time using a timer (not shown). . The timing at which the pump 22 operates can be set by the timer, for example, once every 3 hours during the germination time of the plant V, once every 3 days during the flowering time, and once a week during the harvesting time. It is set to become.
In addition, these timings can change a setting according to the kind of plant V. FIG.
水位調整機構３０は、本実施形態では、サイフォンの原理を利用して植物育成槽１０内の水位を調整するものであり、図２に示すように、植物育成槽１０の底面に貫通して設けられ、養液を植物育成槽１０の外部へ導く導出管３１と、この導出管３１より径が小さく、例えばシール部材３２等を介してこの導出管３１に着脱可能に取り付けられる曲管３３（以下、サイフォン３３とも言う）とを具備している。 In this embodiment, the water level adjusting mechanism 30 adjusts the water level in the plant growing tank 10 using the principle of siphon, and is provided so as to penetrate the bottom surface of the plant growing tank 10 as shown in FIG. The lead-out pipe 31 that guides the nutrient solution to the outside of the plant growing tank 10 and a curved pipe 33 (hereinafter referred to as “removable” pipe 31) that is smaller in diameter than the lead-out pipe 31 and is detachably attached to the lead-out pipe 31 through, for example, a seal member 32 , Also referred to as siphon 33).
本実施形態では、図１に示すように、植物育成槽１０に取り付けられた導出管３１は、当該植物育成槽１０の下段に位置する植物育成槽１０の導入管１１と配管Ｌ２で接続されており、当該植物育成槽１０から排出された養液が下段に位置する植物育成槽１０へ供給されるように構成されている。
なお、最下段に位置する植物育成槽１０の導出管３１は上述した養液貯蓄タンク２１と配管Ｌ３で接続されており、排出された養液が養液貯蓄タンク２１へ戻るように構成されている。
In this embodiment, as shown in FIG. 1, the outlet pipe 31 attached to the plant growing tank 10 is connected to the introduction pipe 11 of the plant growing tank 10 located at the lower stage of the plant growing tank 10 by a pipe L2. The nutrient solution discharged from the plant growing tank 10 is supplied to the plant growing tank 10 located in the lower stage.
In addition, the outlet pipe 31 of the plant growing tank 10 located at the lowermost stage is connected to the nutrient solution storage tank 21 and the pipe L3 described above, and the discharged nutrient solution is configured to return to the nutrient solution storage tank 21. Yes.
サイフォン３３は、図２に示すように、一端開口３３１及び他端開口３３２が平行に位置するように湾曲して形成された管であり、一端開口３３１が、植物育成槽１０の第２領域１０２における底面から所定距離離間して位置し、他端開口３３２が、植物育成槽１０の外に位置するように、前記導出管３１に取り付けられている。このようにサイフォン３３を取り付けることにより、植物育成槽１０内の水位が上昇してサイフォン３３の頂部３３３が位置する高さに達すると、サイフォンの原理により、養液が一端開口３３１からサイフォン３３に流入するとともに、他端開口３３２から導出管３１へ流れ始め、水位は、頂部３３３が位置する高さから一端開口３３１が位置する高さまで下がる。 As shown in FIG. 2, the siphon 33 is a tube that is curved so that the one end opening 331 and the other end opening 332 are positioned in parallel, and the one end opening 331 is the second region 102 of the plant growing tank 10. The other end opening 332 is attached to the outlet pipe 31 so as to be located outside the plant growing tank 10. By attaching the siphon 33 in this way, when the water level in the plant growing tank 10 rises and reaches the height at which the top portion 333 of the siphon 33 is located, the nutrient solution is transferred from the one end opening 331 to the siphon 33 according to the principle of the siphon. As it flows in, it begins to flow from the other end opening 332 to the outlet pipe 31, and the water level drops from the height at which the top portion 333 is located to the height at which the one end opening 331 is located.
つまり、本実施形態の水位調整機構３０は、植物育成槽１０内の水位を予め定められた最高到達高さ（サイフォン３３の頂部３３３が位置する高さ）まで到達させ、到達と同時に水位を下げ始めて、予め定められた最低到達高さ（サイフォン３３の一端開口３３１が位置する高さ）に到達させるように構成されている。 That is, the water level adjustment mechanism 30 of the present embodiment causes the water level in the plant growing tank 10 to reach a predetermined maximum reached height (the height at which the top portion 333 of the siphon 33 is located), and lowers the water level simultaneously with the arrival. For the first time, it is configured to reach a predetermined minimum reached height (a height at which the one-end opening 331 of the siphon 33 is located).
なお、本実施形態では、植物育成槽１０それぞれにサイフォン３３が１本ずつ取り付けられており、これらのサイフォン３３はいずれも互いに同一形状をなすものである。 In the present embodiment, one siphon 33 is attached to each plant growing tank 10, and these siphons 33 have the same shape.
続いて、植物育成槽１０の第１領域１０１に敷かれた培地４０について説明する。 Next, the culture medium 40 laid in the first region 101 of the plant growing tank 10 will be described.
培地４０は、図３の拡大図に示すように、細長い管状をなす多数の中空体４１を前記第１領域１０１に不規則な向きで入れて形成したものである。 As shown in the enlarged view of FIG. 3, the culture medium 40 is formed by inserting a large number of hollow bodies 41 having an elongated tubular shape into the first region 101 in an irregular direction.
具体的にこれらの中空体４１は、一端及び他端が開口しており、この開口を介して内部空間に養液が出入り可能に構成されている。 Specifically, one end and the other end of these hollow bodies 41 are open, and the nutrient solution can enter and exit through the opening.
各中空体４１の寸法は、互いに等しい寸法であり、具体的には、軸方向及び径方向の寸法が、上述した隔壁すのこ１３に形成された小孔１３１の直径よりも大きい寸法である。 The dimensions of the hollow bodies 41 are equal to each other. Specifically, the dimensions in the axial direction and the radial direction are larger than the diameter of the small hole 131 formed in the partition saw 13 described above.
なお、本実施形態の中空体４１は、例えばプラスチック等の樹脂製のものであり、水よりも比重が大きく、遮光性を有している。 The hollow body 41 of the present embodiment is made of a resin such as plastic, and has a specific gravity greater than that of water and has a light shielding property.
このように構成された本実施形態に係る植物育成装置１００によれば、植物育成槽１０内に養液が供給されて培地４０が養液に浸り、その後、サイフォン３３により養液を排出して水位を下げることで、中空体４１の内部空間に養液が残留するので、この養液中の水分と中空体４１の内部空間や周囲の空気とによって、根菜類等の植物Ｖの育成に適した育成環境を形成することができる。
そのうえ、培地４０を養液に浸す際は、植物育成槽１０に供給された養液がすぐに中空体４１の内部空間に流れ込むので、植物育成槽１０内の水位を速やかに上げることができ、養液を排出する際は、養液がすぐに内部空間から流れ出るので、水位を速やかに下げることができ、上述した育成環境を形成するための水位調整にかかる時間を従来より短くすることができる。
さらには、養液が内部空間に流れ込むことにより、中空体４１は、スポンジ等に比べて浮き上がりにくく、従来のように、スポンジ等の浮き上がりを防ぐためのパネル等を不要にすることができる。
According to the plant growing apparatus 100 according to the present embodiment configured as described above, the nutrient solution is supplied into the plant growing tank 10 so that the culture medium 40 is immersed in the nutrient solution, and then the nutrient solution is discharged by the siphon 33. Since the nutrient solution remains in the internal space of the hollow body 41 by lowering the water level, it is suitable for growing plants V such as root vegetables by the moisture in the nutrient solution and the internal space of the hollow body 41 and the surrounding air. Can create a nurturing environment.
In addition, when the culture medium 40 is immersed in the nutrient solution, the nutrient solution supplied to the plant growing tank 10 immediately flows into the internal space of the hollow body 41, so that the water level in the plant growing tank 10 can be quickly raised. When discharging the nutrient solution, the nutrient solution immediately flows out from the internal space, so that the water level can be lowered quickly, and the time required for the water level adjustment for forming the above-described growth environment can be shortened compared to the conventional method. .
Furthermore, since the nutrient solution flows into the internal space, the hollow body 41 is less likely to float than a sponge or the like, and a panel or the like for preventing the sponge or the like from being lifted can be eliminated as in the prior art.
培地４０が管状をなす中空体４１から形成されているので、培地４０がスポンジ等から形成されている場合に比べて、植物Ｖの根等は、培地４０に絡みにくい。これにより、植物Ｖを収穫した後に培地４０を洗えば、根等と中空体４１とを容易に分離することができるので、中空体４１を再利用して、産業廃棄物を削減することができる。 Since the culture medium 40 is formed from the hollow body 41 having a tubular shape, the roots of the plant V and the like are less likely to be entangled with the culture medium 40 as compared with the case where the culture medium 40 is formed from a sponge or the like. Thereby, if the culture medium 40 is washed after the plant V is harvested, the roots and the hollow body 41 can be easily separated. Therefore, the hollow body 41 can be reused to reduce industrial waste. .
また、プラスチック等の樹脂製の中空体４１から形成される培地４０は軽量であり、この培地４０が敷かれた植物育成槽１０は、上下方向に多段に配置することができるので、植物育成装置１００を設置する工場等の単位面積当たりの栽培密度が減少することはない。 Moreover, since the culture medium 40 formed from the hollow body 41 made of resin such as plastic is lightweight and the plant growth tank 10 on which the culture medium 40 is laid can be arranged in multiple stages in the vertical direction, a plant growth apparatus The cultivation density per unit area of a factory or the like where 100 is installed does not decrease.
さらに、中空体４１の寸法が、隔壁すのこ１３に形成された小孔１３１の径よりも大きいので、中空体４１がこの小孔１３１を通過して第１領域１０１から第２領域１０２へ流れ込むことはなく、サイフォン３３が中空体４１を吸引して詰まることを防ぐことができる。 Furthermore, since the dimension of the hollow body 41 is larger than the diameter of the small hole 131 formed in the partition wall saw 13, the hollow body 41 flows from the first region 101 to the second region 102 through the small hole 131. No, the siphon 33 can prevent the hollow body 41 from being sucked and clogged.
複数の植物育成槽１０が、上下方向に多段に配置されているので、最上段に位置する植物育成槽１０内に養液を所定量だけ供給すれば、養液が上段に位置する植物育成槽１０から下段に位置する植物育成槽１０へ順次流れていくので、植物育成槽１０それぞれに対して個別に養液を供給する場合に比べ、必要な養液全体の量を少なくすることができ、養液貯蓄タンク２１の小型化が可能である。 Since the plurality of plant growing tanks 10 are arranged in multiple stages in the vertical direction, if a predetermined amount of nutrient solution is supplied into the plant growing tank 10 located at the uppermost stage, the plant growing tank in which the nutrient solution is located at the upper stage. Since it flows sequentially from 10 to the plant growth tank 10 located in the lower stage, compared with the case where the nutrient solution is individually supplied to each of the plant growth tanks 10, the total amount of the necessary nutrient solution can be reduced. The nutrient solution storage tank 21 can be downsized.
