Description
本発明は、水耕栽培装置に関し、更に詳しくは、長尺の水槽を構成する水槽本体と水槽本体との継目に段差が生じていたとしても、水槽の上部に載置されたスライド式蓋体が、スムーズに苗を植生する入口側から植物を収穫する出口側へとスライドする水耕栽培装置とそれに用いられる継手に関するものである。 The present invention relates to a hydroponic cultivation apparatus, and more specifically, even if a step is generated at the seam between the aquarium body and the aquarium body constituting the long aquarium, the slide type lid placed on the upper part of the aquarium However, it is related with the hydroponic cultivation apparatus which slides from the entrance side which plants a seedling smoothly to the exit side which harvests a plant, and a coupling used for it.
従来、この種の装置として、長手方向に傾斜して設置されることにより植物に与える養液が内側面に沿って流される樋状部材と、樋状部材の上に互いに隣接して載置され、植物を植栽するための１以上の穴を有する複数の栽培トレイと、樋状部材に養液を供給する養液供給手段と、を備えた植物栽培装置が知られている（特許文献１）。 Conventionally, as a device of this type, a nutrient solution to be given to plants by being inclined in the longitudinal direction is placed adjacent to each other on the rod-shaped member on which the nutrient solution fed along the inner surface flows. A plant cultivation device comprising a plurality of cultivation trays having one or more holes for planting plants and a nutrient solution supply means for supplying nutrient solution to the rod-shaped member is known (Patent Document 1). ).
上記特許文献１において、樋状部材の川上側に、未熟な植物の苗を保持させた栽培トレイを載置するようにし、その植物の成長に合わせて栽培トレイを川上側から川下側に徐々にスライドさせて、最終的にその栽培トレイが樋状部材の最も川下側に位置した際に、栽培トレイを樋状部材から取外し、成熟した植物を収穫するようにした栽培方法が提案されている。 In Patent Document 1, a cultivation tray holding an immature plant seedling is placed on the upper stream side of the bowl-shaped member, and the cultivation tray is gradually moved from the upper stream side to the lower stream side as the plant grows. A cultivation method has been proposed in which, when the cultivation tray is finally positioned on the most downstream side of the rod-shaped member, the cultivation tray is removed from the rod-shaped member and mature plants are harvested.
上記特許文献１の植物栽培装置のように、植物の栽培槽として樋状部材を用いると、樋状部材同士を長手方向に複数接続することにより、栽培領域を自由に設計でき、短尺の箱型栽培槽を複数個設置する場合と比べると、装置全体のコストを抑えることができるというメリットがあった。 When a cocoon-shaped member is used as a plant cultivation tank as in the plant cultivation apparatus of Patent Document 1, the cultivation region can be freely designed by connecting a plurality of cocoon-shaped members in the longitudinal direction, and a short box shape. Compared to the case where a plurality of cultivation tanks are installed, there is an advantage that the cost of the entire apparatus can be suppressed.
しかしながら、上記特許文献１の植物栽培装置のように、樋状部材と樋状部材とを長手方向に接続すると、その継目に段差が生じてしまうことが多く、このように樋状部材と樋状部材の継目に段差が生じると、栽培トレイが苗を植生する入口側（川上側）から植物を収穫する出口側（川下側）へとうまくスライドせずに、生産性に影響を与える恐れがあった。 However, as in the plant cultivation apparatus of Patent Document 1, when the rod-shaped member and the rod-shaped member are connected in the longitudinal direction, a step is often generated at the seam. If there is a step at the joint of the parts, the cultivation tray may not slide well from the inlet side (upstream side) where the seedlings are planted to the outlet side (downstream side) where the plants are harvested, which may affect productivity. It was.
本発明は上記の問題に鑑みてなされたもので、その解決しようとする課題は、長尺の水槽の上部に載置されたスライド式蓋体が、水槽の長手方向にスムーズにスライドする水耕栽培装置とそれに用いられる継手を提供することにある。 The present invention has been made in view of the above problems, and the problem to be solved is hydroponics in which a sliding lid placed on the upper part of a long water tank slides smoothly in the longitudinal direction of the water tank. It is providing the cultivation apparatus and the coupling used for it.
上記目的を達成するため、本発明に係る水耕栽培装置は、
長尺の水槽と、該水槽の上部に載置されるスライド式蓋体とを備えた水耕栽培装置であって、
上記水槽は、断面が略Ｕ字状をした少なくとも２つ以上の水槽本体と、該水槽本体と水槽本体とを養液の流れを妨げないように長手方向に接続する断面が略Ｕ字状の継手から構成されるものであり、
上記スライド式蓋体は、長尺の水槽の上部に載置した際、該水槽の略中央ライン上に位置するように、植物を保持する挿通孔が一定の間隔をあけて複数穿孔された長尺の板状体であり、
上記継手は、その側板が底板からみて中央に向って徐々に高くなるように形成されており、該側板の上端が、互いに隣接する水槽本体の側壁上端のいずれか高い方と同じ、若しくは、高い位置にあること、を特徴とするものである。
In order to achieve the above object, the hydroponic cultivation apparatus according to the present invention comprises:
A hydroponic cultivation apparatus comprising a long aquarium and a sliding lid placed on top of the aquarium,
The water tank has a substantially U-shaped cross section for connecting at least two or more water tank main bodies having a substantially U-shaped cross section, and the water tank main body and the water tank main body in a longitudinal direction so as not to interfere with the flow of nutrient solution . Consisting of joints,
When the slide lid is placed on the upper part of a long aquarium, a plurality of insertion holes for holding plants are formed at regular intervals so that the slide lid is positioned on a substantially central line of the aquarium. A plate-like body of the scale,
The joint is formed such that its side plate gradually increases toward the center when viewed from the bottom plate , and the upper end of the side plate is the same as or higher than the higher one of the upper ends of the side walls of adjacent water tank bodies. It is characterized by being in a position.
本発明の水耕栽培装置においては、上記水槽本体と継手とが、継手の内周面又は外周面に設けられた水槽本体の端部を嵌入する係合突起により係合していることが好ましい。また、上記継手が外継手であって、その内周面に係合突起が設けられており、水槽本体と継手が係合した際に、継手の内周面の底部に段差のない平らな面があることが好ましく、上記係合突起を、水槽本体の内周面に設けられた中空状の嵌入スペースに嵌入して、水槽本体と継手とを係合させた水耕栽培装置も好ましい。 In the hydroponic cultivation apparatus of the present invention, it is preferable that the water tank main body and the joint are engaged by an engagement protrusion that fits an end of the water tank main body provided on the inner peripheral surface or the outer peripheral surface of the joint. . In addition, the joint is an outer joint, and an engagement protrusion is provided on the inner peripheral surface thereof. When the water tank body and the joint are engaged, there is no step at the bottom of the inner peripheral surface of the joint. A hydroponic cultivation apparatus in which the engagement protrusion is inserted into a hollow insertion space provided on the inner peripheral surface of the water tank main body and the water tank main body and the joint are engaged is also preferable.
次に、本発明の継手は、上記いずれかの構成の水耕栽培装置に用いられる継手であって、その側板が、水槽本体との接続方向の端部から中央に向って徐々に高くなるように形成されていることを特徴とする。 Next, the joint of the present invention is a joint used in the hydroponic cultivation apparatus having any one of the above configurations, and its side plate gradually increases from the end in the connecting direction to the aquarium body toward the center. It is formed in you characterized.
本発明の水耕栽培装置は、長尺の水槽が、断面が略Ｕ字状をした少なくとも２つ以上の水槽本体と、該水槽本体と水槽本体とを長手方向に接続する断面が略Ｕ字状の継手から構成されるものであることから、運搬性や施工性などを考慮し、水槽本体を切断したとしても、それを継手により接続することにより、長尺の水槽とすることができる。このように、水槽本体同士を複数接続して水槽を構築すると、栽培領域を自由に設計できることから、設計の自由度が高く、短尺の箱型栽培槽を複数個設置する場合と比べると、装置全体のコストを抑えることができる。また、本発明は、長尺の水槽の上部にスライド式蓋体を載置するという構成である。従って、水槽の入口側に、未熟な植物の苗を保持させたスライド式蓋体を載置するようにし、その植物の成長に合わせてスライド式蓋体を入口側から出口側に徐々にスライドさせて、最終的にそのスライド式蓋体が水槽の最も出口側に位置した際に、スライド式蓋体を水槽から取外し、成熟した植物を収穫する栽培方法を採ることができ、生産効率が非常に高い。このような栽培方法においては、水槽本体と水槽本体を接続した際に、その継目に段差が生じてしまうことも多いが、たとえ段差が生じてしまったとしても、継手の側板が中央に向って徐々に高くなるように形成されており、その側板の上端が、水槽本体の側壁上端と同じ、若しくは、それよりも高い位置にあることから、水槽の上部に載置されたスライド式蓋体が、その段差に引っ掛かることはなく、水槽の長手方向にスムーズにスライドするため、生産性に影響を与える心配は皆無に等しい。 In the hydroponic cultivation apparatus of the present invention, the long water tank has a substantially U-shaped cross section that connects at least two water tank bodies having a substantially U-shaped cross section and the water tank body and the water tank body in the longitudinal direction. Even if the water tank main body is cut in consideration of transportability, workability, and the like, a long water tank can be obtained by connecting it with the joint. In this way, when the aquarium is constructed by connecting a plurality of aquarium bodies, the cultivation area can be designed freely, so the degree of freedom in design is high, compared to the case where a plurality of short box-shaped cultivation tanks are installed. The overall cost can be reduced. Moreover, this invention is the structure of mounting a slide type cover body on the upper part of a long water tank. Therefore, a sliding lid holding an immature plant seedling is placed on the inlet side of the aquarium, and the sliding lid is gradually slid from the inlet side to the outlet side as the plant grows. Finally, when the sliding lid is located at the most outlet side of the aquarium, it is possible to remove the sliding lid from the aquarium and take a cultivation method to harvest mature plants. high. In such a cultivation method, when the aquarium body and the aquarium body are connected, a step is often generated at the joint, but even if a step is generated, the side plate of the joint faces the center. Since the upper end of the side plate is the same as or higher than the upper end of the side wall of the aquarium body, the sliding lid placed on the upper part of the aquarium has Because it slides smoothly in the longitudinal direction of the aquarium without being caught by the step, there is no concern about affecting the productivity.
また、上記水槽本体と継手とが、継手の内周面又は外周面に設けられた水槽本体の端部を嵌入する係合突起により係合している水耕栽培装置は、継手の係合突起に水槽本体の端部を挿入するという簡易な作業により、水槽本体と継手とが強固に係合する。従って、水槽本体と水槽本体とを、継手を介して、簡単且つ確実に接続することができる。 Further, the hydroponic cultivation apparatus in which the water tank main body and the joint are engaged by an engagement protrusion that fits an end of the water tank main body provided on the inner peripheral surface or the outer peripheral surface of the joint is an engagement protrusion of the joint. By the simple operation of inserting the end of the water tank body into the water tank body, the water tank body and the joint are firmly engaged. Therefore, the water tank body and the water tank body can be easily and reliably connected via the joint.
さらに、上記継手が外継手であって、その内周面に係合突起が設けられており、水槽本体と継手が係合した際に、継手の内周面の底部に段差のない平らな面がある水耕栽培装置のように、継手が外継手であると、水槽本体と継手が係合した際に、継手の内周面の底部に段差のない平らな面を形成することが可能となる。このように段差のない平らな面が形成されると、入口側から出口側へと流れる養液の流れを妨げることがなくなり、また、養液が水槽本体と水槽本体との接続箇所近傍に留まってしまうこともないため、出口側の植物へも十分な養液を供給することができるようになり、段差部に切断された根や根からの老廃物及び異物が溜まることなく掃除も容易になる。 Further, the joint is an outer joint, and an engagement protrusion is provided on the inner peripheral surface thereof. When the water tank body and the joint are engaged, a flat surface without a step at the bottom of the inner peripheral surface of the joint. When the joint is an outer joint, like a hydroponic cultivation apparatus, when the water tank body and the joint are engaged, it is possible to form a flat surface without a step at the bottom of the inner peripheral surface of the joint. Become. When a flat surface without a step is formed in this way, the flow of the nutrient solution flowing from the inlet side to the outlet side is not obstructed, and the nutrient solution remains in the vicinity of the connection point between the water tank body and the water tank body. Therefore, it becomes possible to supply sufficient nutrient solution to the plant on the exit side, and it is easy to clean without collecting waste and foreign matter from the roots and roots cut at the stepped part. Become.
特に、上記係合突起を、水槽本体の内周面に設けられた中空状の嵌入スペースに嵌入して、水槽本体と継手とを係合させた水耕栽培装置であれば、係合突起が水槽本体の耳部に嵌入されて隠れることから、継手の内周面全域に亘って、段差のない平らな面を形成することができる。 In particular, if the engaging protrusion is a hydroponic cultivation apparatus in which the engaging protrusion is inserted into a hollow insertion space provided on the inner peripheral surface of the aquarium body and the aquarium body and the joint are engaged, the engaging protrusion is Since it is inserted and hidden in the ear | edge part of a water tank main body, a flat surface without a level | step difference can be formed over the inner peripheral surface whole region of a coupling.
次に、本発明の継手は、前述したような優れた作用効果を奏する水耕栽培装置を、水槽本体同士を接続するという簡易な作業により、構築することができる。 Next, the joint of this invention can construct | assemble the hydroponic cultivation apparatus which has the outstanding effect as mentioned above by the simple operation | work of connecting aquarium main bodies.
以下、図面を参照して本発明の具体的な実施形態を詳述する。 Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
本発明は、天候や害虫の影響を殆ど受けることがなく、効率良く植物３を栽培できることから、近年注目されている水耕栽培装置１００であって、図１、図２に示すように、養液５を溜める長尺の水槽１と、該水槽１の長手方向と直交するように水槽１の上部に載置されるスライド式蓋体２とを備える。 The present invention is a hydroponic cultivation apparatus 100 that has been attracting attention in recent years because it can cultivate the plant 3 efficiently without being affected by the weather and pests. As shown in FIG. 1 and FIG. A long water tank 1 for storing the liquid 5 and a sliding lid 2 placed on the upper part of the water tank 1 so as to be orthogonal to the longitudinal direction of the water tank 1 are provided.
上記長尺の水槽１は、図４に示すように、少なくとも２つ以上の水槽本体１０と、該水槽本体１０と水槽本体１０とを長手方向に接続する継手１１から構成されている。この長尺の水槽１には、入口側から出口側に養液５を流す関係から、１／１００００〜５／１００程度の若干の流れ勾配が設けられていることが一般的であるが、栽培方式若しくは停電などにより、養液５を供給できなくなった時の対応のために、養液５が若干滞溜する程度の逆勾配を設けることを妨げない。 As shown in FIG. 4, the long water tank 1 is composed of at least two water tank bodies 10 and a joint 11 that connects the water tank body 10 and the water tank body 10 in the longitudinal direction. The long aquarium 1 is generally provided with a slight flow gradient of about 1/10000 to 5/100 because the nutrient solution 5 flows from the inlet side to the outlet side. In order to cope with the case where the nutrient solution 5 can no longer be supplied due to a method or a power failure, it is not hindered to provide a reverse gradient such that the nutrient solution 5 is slightly accumulated.
上記水槽本体１０は、住宅に好適に用いられる合成樹脂製の雨樋を有効利用したものであって、図５に示すように、底壁１０ａと、底壁１０ａの両端から立ち上がる側壁１０ｂ，１０ｂからなる断面が略Ｕ字状のものであり、両側壁１０ｂ，１０ｂの上端には、スライド式蓋体２を載置する耳部１０ｃ，１０ｃが設けられている。この水槽本体１０は、住宅の雨樋であることから、本来であれば長尺状のものであるが、運搬時に荷台に積載される関係から、荷台の大きさに合わせて切断されることもある。また、複数の水槽本体１０を用いて、それらを長手方向に接続すると、植物３の栽培領域を自由に設計でき、短尺の箱型栽培槽を複数個設置する場合と比べると、装置全体のコストを抑えることができるというメリットもある。そこで、本発明の水耕栽培装置１００は、複数の水槽本体１０同士を、次に説明する継手１１により接続することによって、栽培領域の設計の自由度を向上させている。 The water tank body 10 is an effective use of a synthetic resin rain gutter suitably used in a house. As shown in FIG. 5, the bottom wall 10a and side walls 10b and 10b rising from both ends of the bottom wall 10a are used. The cross section which consists of this is a substantially U-shaped thing, and the ear | edge parts 10c and 10c which mount the slide type cover body 2 are provided in the upper end of both side wall 10b, 10b. Since this aquarium body 10 is a rain gutter in a house, it is originally a long one. However, from the relationship of being loaded on the cargo bed during transportation, it can be cut according to the size of the cargo bed. is there. Moreover, if they are connected in the longitudinal direction using a plurality of water tank main bodies 10, the cultivation area of the plant 3 can be freely designed, and the cost of the entire apparatus is compared with the case where a plurality of short box-shaped cultivation tanks are installed. There is also an advantage that can be suppressed. Then, the hydroponic cultivation apparatus 100 of this invention has improved the freedom degree of the design of a cultivation area | region by connecting the some tank main bodies 10 with the coupling 11 demonstrated below.
即ち、水槽本体１０と水槽本体１０とを長手方向に接続する継手１１は、図４、図６に示すように、底板１１ａと、底板１１ａの両端から立ち上がる側板１１ｂ，１１ｂからなる断面が略Ｕ字状の外継手であり、その側板１１ｂの上部には、図８に示すように、中央に向って徐々に高くなる円弧状の凸曲部１１ｃが形成されている。この凸曲部１１ｃは、中央に向って徐々に高くなるように形成されていることから、中央が一番高くて、両端が一番低い。その中央と両端の高低差Ｈは０．１〜２０．０ｍｍ程度になっている。 That is, the joint 11 that connects the aquarium body 10 and the aquarium body 10 in the longitudinal direction has a substantially U-shaped cross section composed of a bottom plate 11a and side plates 11b, 11b rising from both ends of the bottom plate 11a, as shown in FIGS. As shown in FIG. 8, an arc-shaped convex curved portion 11c that gradually increases toward the center is formed on the upper portion of the side plate 11b. Since this convex-curved part 11c is formed so that it may become high gradually toward the center, the center is the highest and both ends are the lowest. The height difference H between the center and both ends is about 0.1 to 20.0 mm.
上記継手１１の凸曲部１１ｃは、水槽本体１０と水槽本体１０を長手方向に接続した際に、一方の水槽本体１０の側壁１０ｂ上端と、もう一方の水槽本体１０の側壁１０ｂ上端との間に高さ方向の段差が生じたとしても、その上に載置されるスライド式蓋体２が、その段差に引っ掛かることなくスムーズにスライドするように形成されたものである。従って、凸曲部１１ｃの両端は、水槽本体１０の側壁１０ｂの上端よりも、０．５〜５．０ｍｍ程度やや低い位置にある。また、凸曲部１１ｃの一番高い位置にある中央は、少なくとも水槽本体１０の側壁１０ｂよりも同じ高さかそれより高い位置にある必要があり、水槽本体１０同士を接続した際の段差を考慮すると、水槽本体１０の側壁１０ｂ上端（段差が生じたと仮定した場合の高い方の側壁１０ｂ上端）よりも０〜５．０ｍｍ程度高い位置にあることが好ましい。 When the water tank main body 10 and the water tank main body 10 are connected in the longitudinal direction, the convex bent portion 11c of the joint 11 is between the upper end of the side wall 10b of one water tank main body 10 and the upper end of the side wall 10b of the other water tank main body 10. Even if a step in the height direction occurs, the slide type lid 2 placed thereon is formed so as to slide smoothly without being caught by the step. Therefore, both ends of the convex curve portion 11 c are at a position slightly lower than the upper end of the side wall 10 b of the water tank body 10 by about 0.5 to 5.0 mm. Moreover, the center in the highest position of the convex part 11c needs to be at least the same height as the side wall 10b of the water tank main body 10 or higher than that, and considers the level difference when the water tank main bodies 10 are connected to each other. Then, it is preferable that it exists in the position about 0-5.0 mm higher than the side wall 10b upper end (the upper side wall 10b upper end when it assumes that the level | step difference arises) of the water tank main body 10. FIG.
上記のように、継手１１の凸曲部１１ｃの両端が水槽本体１０の側壁１０ｂ上端よりも０．５〜５．０ｍｍ程度低い位置にあり、中央が水槽本体１０の側壁１０ｂ上端よりも０〜５．０ｍｍ程度高い位置にあると、図８の仮想線に示すように、入口側の水槽本体１０に載置されているスライド式蓋体２を、出口側の水槽本体１０の方向へスライドさせた際、スライド式蓋体２の出口側端面が継手１１の入口側端面に引っ掛かることはない。そして、凸曲部１１ｃと側壁１０ｂ上端の高さ位置が同じになる交点より、スライド式蓋体２は凸曲部１１ｃに乗り上げて、その上をスライドするようになる。このとき、凸曲部１１ｃは中央に向って徐々に高くなるよう滑らかな曲線を描いているため、水槽本体１０（側壁１０ｂ上端）と継手１１（凸曲部１１ｃ）との交点で引っ掛かることなく、スライド式蓋体２は凸曲部１１ｃにスムーズに移行し、その滑らかな曲線に沿って凸曲部１１ｃの上をスライドすることになる。 As described above, both ends of the convex portion 11 c of the joint 11 are at a position lower by about 0.5 to 5.0 mm than the upper end of the side wall 10 b of the water tank body 10, and the center is 0 to 0 from the upper end of the side wall 10 b of the water tank body 10. When the position is higher by about 5.0 mm, the sliding lid 2 placed on the water tank body 10 on the inlet side is slid in the direction of the water tank body 10 on the outlet side, as shown by the phantom line in FIG. In this case, the outlet side end surface of the sliding lid 2 is not caught by the inlet side end surface of the joint 11. Then, from the intersection where the heights of the convex portion 11c and the upper end of the side wall 10b are the same, the sliding lid 2 rides on the convex portion 11c and slides thereon. At this time, since the convex curve part 11c has drawn the smooth curve so that it may become high gradually toward the center, it is not caught at the intersection of the water tank main body 10 (side wall 10b upper end) and the joint 11 (convex curve part 11c). The sliding lid body 2 smoothly transitions to the convex curve portion 11c and slides on the convex curve portion 11c along the smooth curve.
スライド式蓋体２が凸曲部１１ｃの滑らかな曲線に沿ってスライドし、凸曲部１１ｃの最も高い位置にある中央付近に達する際に、水槽本体１０同士の接続端面に段差が生じ、出口側の水槽本体１０の側壁１０ｂ上端が入口側の水槽本体１０の側壁１０ｂよりも高い位置にあったとしても、その位置（出口側の側壁１０ｂ上端）よりも凸曲部１１ｃの中央が高い位置にあることから、スライド式蓋体２はその段差に引っ掛かることなく乗り越えることができる。このように、スライド式蓋体２が凸曲部１１ｃの中央付近を乗り越えたのち、スライド式蓋体２は凸曲部１１ｃの滑らかな曲線に沿ってスムーズに下降し、右側（出口側）の水槽本体１０の耳部１０ｃ，１０ｃに載置されることになり、一方（入口側）の水槽本体１０からもう一方（出口側）の水槽本体１０への移動が完了する。 When the sliding lid 2 slides along the smooth curve of the convex portion 11c and reaches the vicinity of the center at the highest position of the convex portion 11c, a step is generated at the connection end surface between the aquarium bodies 10, and the exit Even if the upper end of the side wall 10b of the water tank body 10 on the side is at a position higher than the side wall 10b of the water tank body 10 on the inlet side, the center of the convex portion 11c is higher than the position (upper end of the side wall 10b on the outlet side). Therefore, the sliding lid body 2 can get over without being caught by the step. In this way, after the sliding lid 2 gets over the vicinity of the center of the convex portion 11c, the sliding lid 2 descends smoothly along the smooth curve of the convex portion 11c, and the right side (exit side) It will be placed on the ears 10c, 10c of the water tank body 10, and the movement from one (inlet side) water tank body 10 to the other (outlet side) water tank body 10 is completed.
上記のように、本発明の水耕栽培装置１００は、水槽本体１０同士を長手方向に接続した際、その継目に高さ方向の段差が生じたとしても、スライド式蓋体２が入口側の水槽本体１０から出口側の水槽本体１０へとスムーズにスライドすることから、入口側の水槽本体１０に、未熟な植物３を保持させたスライド式蓋体２を載置し、その植物３の成長に合わせてスライド式蓋体２を入口側から出口側へと徐々にスライドさせ、そのスライド式蓋体２が最も出口側の水槽本体１０に位置した際に、成熟した植物３を収穫するようにした栽培方法を実施したとしても、生産性に影響を与えることがない。 As described above, when the hydroponics apparatus 100 of the present invention connects the aquarium main bodies 10 to each other in the longitudinal direction, the sliding lid 2 is located on the inlet side even if a step in the height direction occurs at the joint. Since the water tank body 10 slides smoothly from the water tank body 10 to the water tank body 10 on the outlet side, the sliding lid body 2 holding the immature plant 3 is placed on the water tank body 10 on the inlet side, and the plant 3 grows. The slide-type lid 2 is gradually slid from the inlet side to the outlet side in accordance with and the mature plant 3 is harvested when the slide-type lid 2 is positioned in the water tank body 10 on the most outlet side. Even if the cultivation method which was done is implemented, productivity is not affected.
また、上記継手１１には、図６、図７に示すように、厚肉部１１ｅが形成されている。この厚肉部１１ｅは、継手１１の内周面に、その長手方向の中間地点から幅方向に亘って形成されたものであり、その肉厚は、上記水槽本体１０の底壁１０ａ、側壁１０ｂと同じ寸法になっている。そして、この厚肉部１１ｅには、水槽本体１０，１０の端部を嵌入する係合突起１１ｄが設けられている。この係合突起１１ｄは、厚肉部１１ｅの幅方向の略中間地点から上方へ逆Ｔ字型に突設された突出片であり、図８に示すように、係合突起１１ｄと底板１１ａにより略コ字状の水槽本体１０の嵌入スペースが２つ形成される。そして、そのスペースに水槽本体１０，１０の端部が嵌入されることにより、水槽本体１０，１０の端部が上下から挟持されて、水槽本体１０と継手１１とが強固に係合し、結果、水槽本体１０と水槽本体１０が確実に接続されるようになっている。
なお、本実施形態の係合突起１１ｄは、その内周面の底板１１ａの上方に設けられたものであるが、内周面であればどこに形成しても構わない（例えば側板１１ｂ，１１ｂ）ものであり、また、内周面の底板１１ａと側板１１ｂ，１１ｂの双方に設けてもよい。
Further, as shown in FIGS. 6 and 7, a thick portion 11 e is formed in the joint 11. The thick portion 11e is formed on the inner peripheral surface of the joint 11 from the middle point in the longitudinal direction to the width direction, and the thickness thereof is the bottom wall 10a and the side wall 10b of the water tank body 10. It has the same dimensions as The thick portion 11e is provided with an engaging projection 11d into which the ends of the water tank bodies 10 and 10 are fitted. The engaging protrusion 11d is a protruding piece protruding in an inverted T shape upward from a substantially intermediate point in the width direction of the thick portion 11e. As shown in FIG. 8, the engaging protrusion 11d is formed by the engaging protrusion 11d and the bottom plate 11a. Two insertion spaces for the substantially U-shaped water tank body 10 are formed. And by inserting the edge part of the water tank main body 10 and 10 in the space, the edge part of the water tank main body 10 and 10 is clamped from the upper and lower sides, and the water tank main body 10 and the coupling 11 are engaged firmly. The water tank body 10 and the water tank body 10 are securely connected.
In addition, although the engagement protrusion 11d of this embodiment is provided above the bottom plate 11a of the inner peripheral surface, it may be formed anywhere as long as it is an inner peripheral surface (for example, side plates 11b and 11b). Moreover, you may provide in both the bottom plate 11a and the side plates 11b and 11b of an internal peripheral surface.
上記係合突起１１ｄに水槽本体１０の端部を嵌入すると、係合突起１１ｄの厚み分は上方に突出することになるが、それ以外（係合突起１１ｄが設けられていない箇所）の厚肉部１１ｅは、水槽本体１０の底壁１０ａ、側壁１０ｂと同じ肉厚であることから、水槽本体１０と面一になり、そこには段差のない平らな面が形成される。このように段差のない平らな面が形成されると、入口側から出口側へと流れる養液５の流れを妨げることがなくなり、また、養液５が水槽本体１０同士の接続箇所近傍に留まってしまうこともないため、出口側の植物へも十分な養液５を供給することができるようになり、段差部に切断された根３ａや根３ａからの老廃物及び異物が溜まることなく掃除も容易になる。 When the end of the water tank main body 10 is fitted into the engaging protrusion 11d, the thickness of the engaging protrusion 11d protrudes upward, but the other (the portion where the engaging protrusion 11d is not provided) is thick. Since the part 11e is the same thickness as the bottom wall 10a and the side wall 10b of the water tank main body 10, it becomes flush with the water tank main body 10, and a flat surface without a step is formed there. When a flat surface having no step is formed in this way, the flow of the nutrient solution 5 flowing from the inlet side to the outlet side is not hindered, and the nutrient solution 5 stays in the vicinity of the connection portion between the water tank bodies 10. Therefore, sufficient nutrient solution 5 can be supplied to the plant on the outlet side, and the root 3a cut at the stepped portion and the waste and foreign matter from the root 3a are cleaned without accumulating. Will also be easier.
上記継手１１は、内継手であることを排除するものではないが、継手１１が内継手であると、水槽本体１０との接続箇所にどうしても段差が生じてしまうことから、継手１１は本実施形態のような外継手であることが好ましい。 The joint 11 does not exclude the fact that it is an inner joint. However, if the joint 11 is an inner joint, a step is inevitably generated at the connection point with the water tank body 10, and therefore the joint 11 is the embodiment. Such an outer joint is preferable.
次に、前述した長尺の水槽１に載置されるスライド式蓋体２は、図１に示すように、該水槽１の長手方向と直交するように複数の水槽１の上部に載置される長尺の板状体であって、図３の（ｂ）に示すように、スライド式蓋体２を長尺の水槽１の上部に載置した際、該水槽１の略中央ラインＬ上の位置に、植物３を保持する挿通孔２ａが一定の間隔をあけて複数穿孔されている。上記の実施態様においては、1枚のスライド式蓋体２が複数の水槽１を横断する形で載置されているが、スライド式蓋体２が一つの水槽１に載置された形式で使用してもよい。 Next, as shown in FIG. 1, the sliding lid body 2 placed on the long water tank 1 is placed on top of the plurality of water tanks 1 so as to be orthogonal to the longitudinal direction of the water tank 1. When the sliding lid 2 is placed on the upper part of the long water tank 1, as shown in FIG. 3 (b), on the substantially center line L of the water tank 1. In this position, a plurality of insertion holes 2a for holding the plant 3 are perforated at regular intervals. In the above embodiment, one slide-type lid 2 is placed so as to cross a plurality of water tanks 1, but the slide-type lid 2 is used in a form where it is placed on one water tank 1. May be.
上記のように、長尺の水槽１を幅方向に複数並列し、その上に植物３を保持する挿通孔２ａが複数穿孔されたスライド式蓋体２を載置することにより、一枚のスライド式蓋体２に大量の植物３を保持することができるようになり、生産性が非常に良好となる。 As described above, a plurality of long water tanks 1 are juxtaposed in the width direction, and a slide-type lid body 2 having a plurality of insertion holes 2a for holding plants 3 is placed thereon, so that one slide A large amount of plants 3 can be held in the formula lid 2, and the productivity becomes very good.
本発明のような水耕栽培においては、後述する栄養豊富な養液５を植物３に十分供給することから、アオコなどの藻が発生し易い環境となる。アオコなどの藻は、水質浄化など自然環境においては欠かせない存在であるが、水耕栽培において藻が発生すると、養液５の養分が藻に摂取されて植物３の成長が遅くなり、生育不良の原因ともなって好ましくない。藻が発生する一番の要因は光であると言われており、上記のスライド式蓋体２によって養液５に光が照射されないように遮光することが好ましい。従って、スライド式蓋体２は、光の通過を阻止するために、ある程度の厚みを有し、光が通過し難い材質で形成されている必要があることから、その厚みが１〜３０ｍｍ程度の光が通過し難い発泡スチロールやプラスチック板、或いは、プレート１に３０〜１０００μｍ程度の不透過性のアルミフィルム等が貼着されたスライド式蓋体２が好適に用いられる。そして、光の反射を助長して植物３に光をより多く供給するために白色のスライド式蓋体２が好ましく、このようなスライド式蓋体２によって長尺の水槽１の上部開口を覆うようことにより、養液５に光が照射されることが阻止されて、アオコなどの藻が発生することなく、植物３は順調に成長する。 In hydroponics as in the present invention, the nutrient-rich nutrient solution 5 described later is sufficiently supplied to the plant 3, so that an environment in which algae such as green sea bream are likely to be generated is obtained. Algae and other algae are indispensable in the natural environment such as water purification. However, when algae are generated in hydroponics, the nutrients in nutrient solution 5 are ingested by the algae and the growth of plant 3 is slowed down. It is not preferable as a cause of defects. It is said that light is the main cause of the generation of algae, and it is preferable to shield the nutrient solution 5 from being irradiated with light by the above-described slide type lid 2. Therefore, since the sliding lid 2 needs to be formed of a material having a certain thickness and preventing light from passing through in order to prevent light from passing through, the thickness is about 1 to 30 mm. A sliding lid 2 in which light does not easily pass through, such as a polystyrene foam, a plastic plate, or a plate 1 with an impervious aluminum film of about 30 to 1000 μm, etc., is preferably used. A white sliding lid 2 is preferable in order to promote reflection of light and supply more light to the plant 3, and the sliding lid 2 covers the upper opening of the long water tank 1. As a result, the nutrient solution 5 is prevented from being irradiated with light, and the plant 3 grows smoothly without the generation of algae such as sea lions.
上記スライド式蓋体２に保持されて、長尺の水槽１で栽培される植物３は、果物・野菜や鑑賞用植物など多岐に亘り、特に限定されるものではなく、このような植物３がスポンジ状の培地４に囲繞されて、スライド式蓋体２の挿通孔２ａに保持されている。このように植物３がスライド式蓋体２に保持されると、植物３の根３ａが養液５に浸かり、そこから栄養分を吸収して成長する。 The plants 3 that are held by the sliding lid 2 and are cultivated in the long water tank 1 are not particularly limited, such as fruits, vegetables, and ornamental plants. Surrounded by a sponge-like medium 4 and held in the insertion hole 2 a of the sliding lid 2. When the plant 3 is thus held on the sliding lid 2, the root 3 a of the plant 3 is immersed in the nutrient solution 5, and grows by absorbing nutrients therefrom.
上記植物３の栄養分となる養液５は、栽培する植物３ごとに最適成分組成が異なり、また、品種、栽培時期、生育段階、温度、光条件によっても成分組成が変わってくるものではあるが、植物３が根３ａから吸収する必須元素（窒素、リン、カリ、カルシウム、マグネシウム、硫黄、ホウ素、鉄、マンガン、銅、亜鉛、モリブデン、塩素、ニッケル、酸素）が含まれたものを用いる。このような養液５を、苗を植生する入口側から水槽１の内部に流入し、植物３を収穫する出口側に向けて流している。その際、出口側から再び入口側へ養液５を循環させるようにすることが好ましい。なお、養液５を出口側から水槽１の内部に流入し、入口側に向けて流すようにしてもよい。その際、入口側から再び出口側へ養液５を循環させる事もできる。 The nutrient solution 5 serving as a nutrient for the plant 3 has a different optimum component composition for each plant 3 to be cultivated, and the component composition varies depending on the variety, cultivation period, growth stage, temperature, and light conditions. The plant 3 contains an essential element (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, iron, manganese, copper, zinc, molybdenum, chlorine, nickel, oxygen) that is absorbed from the root 3a. Such nutrient solution 5 flows into the inside of the water tank 1 from the entrance side for planting seedlings and flows toward the exit side for harvesting the plants 3. At that time, it is preferable to circulate the nutrient solution 5 from the outlet side to the inlet side again. The nutrient solution 5 may flow into the water tank 1 from the outlet side and flow toward the inlet side. At that time, the nutrient solution 5 can be circulated from the inlet side to the outlet side again.
以上のような部材から構成される本発明の水耕栽培装置１００は、次の手順により設置される。即ち、図３の（ａ）に示すように、水槽本体１０と水槽本体１０とを、継手１１により長手方向に接続する。水槽本体１０同士の長手方向の接続は、双方の端部を、継手１１の係合突起１１ｄの嵌入スペースに嵌入するという簡易な作業により行うことができる。この際、水槽本体１０同士をより強固に接続するため、水槽本体１０端部の外周面及び／又は継手１１の係合突起１１ｄの内周面に接着剤を塗布してもよい。このようにして構築された長尺の水槽１を、幅方向に複数並列する。このとき、幅方向に隣接する長尺の水槽１同士を、係合、係止、嵌合、その他種々の手段により連結してもよい。 The hydroponic cultivation apparatus 100 of the present invention composed of the above members is installed by the following procedure. That is, as shown to (a) of FIG. 3, the water tank main body 10 and the water tank main body 10 are connected to the longitudinal direction by the coupling 11. FIG. Connection of the water tank main bodies 10 in the longitudinal direction can be performed by a simple operation of fitting both ends into the fitting space of the engaging protrusion 11 d of the joint 11. At this time, an adhesive may be applied to the outer peripheral surface of the end of the water tank main body 10 and / or the inner peripheral surface of the engaging protrusion 11d of the joint 11 in order to connect the water tank main bodies 10 more firmly. A plurality of the long water tanks 1 constructed in this way are arranged in parallel in the width direction. At this time, the long water tanks 1 adjacent to each other in the width direction may be connected by engagement, locking, fitting, or other various means.
上記のように、水槽本体１０同士を継手１１により長手方向に接続することで長尺の水槽１を構築し、図３の（ａ）に示すように、該水槽１を幅方向に複数並列すると、次に、図３の（ｂ）に示すように、長尺の水槽１の長手方向と直交するように、挿通孔２ａに植物３を保持させたスライド式蓋体２を複数枚載置する。このとき、長尺の水槽１の中央ラインＬの上に、スライド式蓋体２の挿通孔２ａが位置するように載置する。長尺の水槽１の上部にスライド式蓋体２を載置すると、最後に、長尺の水槽１の内部空間に養液５を供給し、養液５を入口側から出口側に向けて流すことにより、水耕栽培装置１００が完成する。
なお、長尺の水槽１の上部に、スライド式蓋体２を載置したのち、植物３を挿通孔２ａに保持させてもよい。
As described above, a long water tank 1 is constructed by connecting the water tank main bodies 10 to each other in the longitudinal direction by the joint 11, and when a plurality of the water tanks 1 are juxtaposed in the width direction as shown in FIG. Next, as shown in FIG. 3 (b), a plurality of sliding lids 2 holding the plants 3 in the insertion holes 2 a are placed so as to be orthogonal to the longitudinal direction of the long water tank 1. . At this time, it mounts so that the insertion hole 2a of the slide-type cover body 2 may be located on the center line L of the elongate water tank 1. FIG. When the slide-type lid 2 is placed on the upper part of the long water tank 1, finally, the nutrient solution 5 is supplied to the internal space of the long tank 1, and the nutrient solution 5 flows from the inlet side toward the outlet side. Thereby, the hydroponic cultivation apparatus 100 is completed.
Note that the plant 3 may be held in the insertion hole 2 a after the sliding lid 2 is placed on the upper part of the long water tank 1.
上記のように、長尺の水槽１の上部にスライド式蓋体２を載置する際は、図９の（ａ）に示すように、入口側（川上側）に、未熟な植物３を保持させたスライド式蓋体２を載置するようにし、図９の（ｂ）に示すように、植物３の成長に合わせてスライド式蓋体２を入口側から出口側（川下側）に徐々にスライドさせて、図９の（ｃ）に示すように、最終的にそのスライド式蓋体２が長尺の水槽１の最も出口側に位置した際に、長尺の水槽１からスライド式蓋体２を取外して、成熟した植物３を収穫すると共に、新たな植物３を保持させたスライド式蓋体２を最も入口側に載置する。このように、植物３の成長に合わせてスライド式蓋体２を入口側から出口側に徐々にスライドさせると、水槽本体１０同士の接続部分の継目を通過するが、たとえ、その継目に段差が生じていたとしても、前述したように、水槽本体１０同士を接続する継手１１に凸曲部１１ｃを設けているため、段差に引っ掛かることなく、スライド式蓋体２はスムーズに段差を乗り越えて出口側の水槽本体１０へとスライドする。従って、これを繰り返すことにより、天候や害虫の影響を殆ど受けることなく、効率良く植物３を栽培することができる。 As described above, when the sliding lid 2 is placed on the upper part of the long water tank 1, as shown in FIG. 9A, the immature plant 3 is held on the inlet side (upstream side). As shown in FIG. 9B, the sliding lid 2 is gradually moved from the inlet side to the outlet side (downstream side) as the plant 3 grows. As shown in FIG. 9C, when the sliding lid 2 is finally located at the most outlet side of the long water tank 1, the sliding lid body is moved from the long water tank 1. 2, the mature plant 3 is harvested, and the sliding lid 2 holding the new plant 3 is placed on the most entrance side. In this way, when the sliding lid 2 is gradually slid from the inlet side to the outlet side in accordance with the growth of the plant 3, the seam of the connecting portion between the aquarium bodies 10 passes through. Even if it occurs, as described above, since the convex portion 11c is provided in the joint 11 that connects the aquarium bodies 10 to each other, the sliding lid 2 can easily get over the step without being caught by the step. Slide to the water tank body 10 on the side. Therefore, by repeating this, the plant 3 can be efficiently cultivated with almost no influence from the weather or pests.
上記説明から明らかなように、本発明の水耕栽培装置１００は、水槽本体１０同士を複数接続して長尺の水槽１を構築することにより、栽培領域を自由に設計でき、短尺の箱型栽培槽を複数個設置する場合と比べると、装置全体のコストを抑えることができる。そして、長尺の水槽１と直交するようにスライド式蓋体２を載置するという構成を採用することにより、長尺の水槽１の入口側に、未熟な植物３を保持させたスライド式蓋体２を載置するようにし、その植物３の成長に合わせてスライド式蓋体２を入口側から出口側に徐々にスライドさせて、最終的にそのスライド式蓋体２が水槽１の最も出口側に位置した際に、スライド式蓋体２を水槽１から取外し、成熟した植物３を収穫するという生産性が非常に高い栽培方法を採ることができる。この際、水槽本体１０同士の接続部分に段差が生じてしまうこともあるが、たとえ段差が生じてしまったとしても、継手１１には、中央に向って徐々に高くなる凸曲部１１ｃが形成されていることから、その段差にスライド式蓋体２が引っ掛かることはなく、長尺の水槽１の長手方向にスムーズにスライドするため、生産性に影響を与える心配は皆無に等しい。 As is clear from the above description, the hydroponic cultivation apparatus 100 of the present invention can design a cultivation region freely by connecting a plurality of aquarium bodies 10 to each other to construct a long aquarium 1, and a short box shape. Compared with the case where a plurality of cultivation tanks are installed, the cost of the entire apparatus can be reduced. Then, by adopting a configuration in which the sliding lid 2 is placed so as to be orthogonal to the long aquarium 1, the sliding lid that holds the immature plant 3 on the inlet side of the long aquarium 1. The body 2 is placed, and the sliding lid 2 is gradually slid from the inlet side to the outlet side as the plant 3 grows, and finally the sliding lid 2 is the most outlet of the water tank 1. When positioned on the side, the cultivation method of removing the sliding lid 2 from the water tank 1 and harvesting the mature plant 3 can be adopted. At this time, a step may occur in the connection portion between the water tank bodies 10, but even if a step occurs, the joint 11 is formed with a convex curved portion 11 c that gradually increases toward the center. Therefore, the slide-type lid 2 is not caught on the step, and smoothly slides in the longitudinal direction of the long water tank 1, so that there is no concern about affecting the productivity.
図１０は本発明の他の実施形態に係る水耕栽培装置に用いる継手を示す斜視図、図１１は同装置の長尺の水槽の斜視図である。 FIG. 10 is a perspective view showing a joint used in a hydroponic cultivation apparatus according to another embodiment of the present invention, and FIG. 11 is a perspective view of a long water tank of the apparatus.
本実施形態の水耕栽培装置１００は、図１０に示す継手１１０を用いて、水槽本体１０同士を接続し、長尺の水槽１を構築したものである。この継手１１０は、前述した図１〜図８に示す継手１１と同様に、底板１１ａと、底板１１ａの両端から立ち上がる側板１１ｂ，１１ｂからなる断面が略Ｕ字状の外継手であり、その側板１１ｂの上部には、中央に向って徐々に高くなる円弧状の凸曲部１１ｃが形成されている。 The hydroponics apparatus 100 of this embodiment connects the aquarium main bodies 10 using the coupling 110 shown in FIG. 10, and constructs the elongate aquarium 1. FIG. This joint 110 is an outer joint having a substantially U-shaped cross section consisting of a bottom plate 11a and side plates 11b and 11b rising from both ends of the bottom plate 11a, similar to the joint 11 shown in FIGS. An arcuate convex curved portion 11c that gradually increases toward the center is formed on the upper portion of 11b.
また、この継手１１０の内周面にも、その長手方向の中間地点から幅方向に亘って厚肉部１１ｅが形成されている。前述した図１〜図９に示す実施形態の継手１１の係合突起１１ｄは、この厚肉部１１ｅの幅方向の略中間地点（換言すれば底板１１ａの中間地点）から上方へ逆Ｔ字型に突設されていたものであるのに対して、本実施形態の継手１１０は、図１０に示すように、側板１１ｂ，１１ｂの内周面の上部と下部に、それぞれ係合突起１１０ｄ，１１１ｄが設けられている。この係合突起１１０ｄ，１１１ｄは、長尺の水槽１の入口側と出口側に向ってそれぞれ突設された４本の楕円形のピン体であって、先端（入口側又は出口側）に向って徐々に縮径されている。この係合突起１１０ｄ，１１１ｄは、図１１に示すように、水槽本体１０の側壁１０ｂの上部と下部にそれぞれ設けられた中空挿入部１０ｄ，１０ｅに嵌入される関係から、上側の係合突起１１０ｄの方が下側の係合突起１１１ｄよりも、その径が大きくなっている。 A thick portion 11e is also formed on the inner peripheral surface of the joint 110 from the middle point in the longitudinal direction to the width direction. The engaging protrusion 11d of the joint 11 of the embodiment shown in FIGS. 1 to 9 is an inverted T-shape upward from a substantially middle point in the width direction of the thick portion 11e (in other words, a middle point of the bottom plate 11a). In contrast, as shown in FIG. 10, the joint 110 according to this embodiment is provided with engaging protrusions 110d and 111d on the upper and lower portions of the inner peripheral surfaces of the side plates 11b and 11b, respectively. Is provided. The engaging protrusions 110d and 111d are four oval pin bodies protruding toward the inlet side and the outlet side of the long water tank 1, respectively, and facing the tip (inlet side or outlet side). The diameter is gradually reduced. As shown in FIG. 11, the engagement protrusions 110d and 111d are inserted into the hollow insertion portions 10d and 10e provided at the upper and lower portions of the side wall 10b of the water tank body 10, respectively.

本実施形態の水耕栽培装置１００のその他の構成は、前述した図１〜図９に示すものと同様であるため、同一部材に同一符号を附して説明を省略する。
In order to connect the water tank main bodies 10 to each other using the joint 110, the engagement protrusion 110d on the upper side of the side plate 11b of the joint 110 is a hollow insertion space provided on the upper part of the side wall 10b of the water tank main body 10. The fitting projection 111d on the lower side of the joint 110 may be fitted into the hollow insertion portion 10e provided at the lower portion of the water tank body 10 while being fitted into the hollow insertion portion 10d. In that case, it is preferable to apply | coat an adhesive agent to the outer peripheral surface of engagement protrusion 110d, 111d and / or the inner peripheral surface of hollow insertion part 10d, 10e of the water tank main body 10. FIG.
Since the other structure of the hydroponic cultivation apparatus 100 of this embodiment is the same as that of what was shown in FIGS. 1-9 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.
以上のような構成の水耕栽培装置１００は、継手１１０の係合突起１１０ｄ，１１１ｄを、水槽本体１０の中空挿入部１０ｄ，１０ｅに嵌入した際、上記のように、係合突起１１０ｄ，１１１ｄが厚肉部１１ｅ側に向う程、径が大きくなっていくことから、厚肉部１１ｅに水槽本体１０の端部が当接するときには、非常に強い摩擦力が働く。従って、この継手１１０を用いて水槽本体１０同士を接続すると、接着剤が硬化する前であっても、水槽本体１０同士の接続が、解除されてしまう心配が無い。また、水槽本体１０，１０と継手１１０の内周面全てに、段差のない平らな面を形成できるというメリットもある。 The hydroponic cultivation apparatus 100 configured as described above has the engagement protrusions 110d and 111d as described above when the engagement protrusions 110d and 111d of the joint 110 are fitted into the hollow insertion portions 10d and 10e of the aquarium body 10, respectively. Since the diameter becomes larger toward the thick part 11e, a very strong frictional force is applied when the end of the water tank body 10 comes into contact with the thick part 11e. Therefore, when the water tank main bodies 10 are connected to each other using the joint 110, there is no fear that the connection between the water tank main bodies 10 is released even before the adhesive is cured. In addition, there is an advantage that a flat surface without a step can be formed on all the inner peripheral surfaces of the water tank bodies 10 and 10 and the joint 110.
図１２は本発明の更に他の実施形態に係る水耕栽培装置を示すものであって、スライド式蓋体を長尺の水槽に載置した状態の部分断面図である。 FIG. 12 shows a hydroponic cultivation apparatus according to still another embodiment of the present invention, and is a partial sectional view showing a state in which a slide type lid is placed on a long water tank.
図１２に示す水耕栽培装置１００は、その両端、即ち、スライド式蓋体２０を長尺の水槽１に載置した際、水槽本体１０の耳部１０ｃ，１０ｃに対向する位置に、凹型の溝部２ｂ，２ｂが形成されたスライド式蓋体２０を用いたものである。この溝部２ｂは、スライド式蓋体２０の下面を、水槽本体１０の耳部１０ｃと略同等ないしやや広い程度に凹型に切り欠いたものであり、スライド式蓋体２０を長尺の水槽１に載置した際、水槽本体１０の耳部１０ｃが、この溝部２ｂに嵌合するようになっている。 The hydroponic cultivation apparatus 100 shown in FIG. 12 is concave at both ends, that is, when the sliding lid 20 is placed on the long water tank 1, at positions facing the ear portions 10 c and 10 c of the water tank body 10. The slide type lid 20 in which the grooves 2b and 2b are formed is used. The groove 2b is formed by cutting the bottom surface of the sliding lid 20 into a concave shape that is substantially equal to or slightly wider than the ear portion 10c of the aquarium body 10, and the sliding lid 20 is formed into a long aquarium 1. When placed, the ear portion 10c of the aquarium body 10 is adapted to fit into the groove portion 2b.
また、上記スライド式蓋体２０には、図１２に示すように、長尺の水槽１の上部に載置した際、該水槽１の略中央ラインＬ上の位置に、複数の凹部２ｃが一定の間隔をあけて設けられている。そして、この凹部２ｃの底面には、植物３を保持する挿通孔２ａが、一定の間隔をあけて複数穿孔されている。
本実施形態の水耕栽培装置１００のその他の構成は、前述した図１〜図９に示すものと同様であるため、同一部材に同一符号を附して説明を省略する。
Further, as shown in FIG. 12, when the slide type lid 20 is placed on the upper part of the long water tank 1, a plurality of concave portions 2 c are fixed at positions substantially on the center line L of the water tank 1. Are provided at intervals. A plurality of insertion holes 2a for holding the plant 3 are perforated at regular intervals on the bottom surface of the recess 2c.
Since the other structure of the hydroponic cultivation apparatus 100 of this embodiment is the same as that of what was shown in FIGS. 1-9 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.
この図１２に示す水耕栽培装置１００は、スライド式蓋体２０の溝部２ｂが、水槽本体１０の耳部１０ｃに嵌まり込むんで確実に嵌合することから、スライド式蓋体２を、入口側から出口側にスライドさせた際のズレ（水槽本体１０の幅方向のズレ）を防止することができる。また、前述した図１〜図９に示す実施形態のスライド式蓋体２の場合は、植物３が大きく成長すると、スライド式蓋体２を入口側から出口側に向けてスライドさせた際に、該植物３が傾いてしまうこともある。しかしながら、本実施形態のスライド式蓋体２０は、上記のように、凹部２ｃを設けているため、その内周面（土手部分）が植物３を確実に支持し、植物３が傾いたとしても傾き過ぎるという不具合を解消することができる。さらに、凹部２ｃの底面に植物３を保持する挿通孔２ａが設けられており、この凹部２ｃの挿通孔２ａに植物３を保持させると、前述した図１〜図９に示す実施形態のスライド式蓋体２と比較すると、根３ａが低い位置にくる。これを換言すれば、根３ａから養液５までの距離が近いということであり、長尺の水槽１に供給する養液５の量を、前述した図１〜図９に示す実施形態の水耕栽培装置１００と比べて、減らすことができる。このように、養液５の供給量を少なくすると、水槽本体１０等に加わる重量も減少し、結果として、水槽本体１０の構造を簡易化することにより強度を低く抑えても、破損の心配が生じることがなくなる。
なお、図示はしないが、底面の位置が異なる複数の凹部２ｃが設けられたスライド式蓋体２０を用いると、植物３の種類や供給する養液５の水量に応じて使い分けができるので、より好ましくなる。
The hydroponic cultivation apparatus 100 shown in FIG. 12 is configured such that the groove 2b of the sliding lid 20 is fitted into the ear 10c of the aquarium body 10 so that the sliding lid 2 can be securely fitted. It is possible to prevent a shift (a shift in the width direction of the water tank body 10) when sliding from the side to the outlet side. Moreover, in the case of the sliding lid body 2 of the embodiment shown in FIGS. 1 to 9 described above, when the plant 3 grows greatly, when the sliding lid body 2 is slid from the inlet side toward the outlet side, The plant 3 may tilt. However, since the sliding lid 20 of the present embodiment is provided with the recess 2c as described above, even if the inner peripheral surface (bank portion) reliably supports the plant 3 and the plant 3 is inclined. The problem of tilting too much can be solved. Further, an insertion hole 2a for holding the plant 3 is provided on the bottom surface of the recess 2c. When the plant 3 is held in the insertion hole 2a of the recess 2c, the sliding type of the embodiment shown in FIGS. Compared to the lid 2, the root 3 a is at a lower position. In other words, the distance from the root 3a to the nutrient solution 5 is short, and the amount of the nutrient solution 5 supplied to the long water tank 1 is the water of the embodiment shown in FIGS. Compared with the cultivation apparatus 100, it can be reduced. Thus, if the supply amount of the nutrient solution 5 is reduced, the weight applied to the aquarium body 10 and the like is also reduced. As a result, even if the strength is reduced by simplifying the structure of the aquarium body 10, there is a risk of damage. No longer occurs.
In addition, although not shown in figure, when the slide type cover body 20 provided with the several recessed part 2c from which the position of a bottom face is provided can be selectively used according to the kind of plant 3 and the amount of the nutrient solution 5 to be supplied. It becomes preferable.
