Description

この発明は、植物工場で用いる植物栽培装置に関する。 The present invention relates to a plant cultivation device used in a plant factory.

植物工場は植物の栽培環境を人工的に制御することで、季節を選ばず一定品質の作物を安定的に収穫することができる。植物工場では光を日光に頼ることなく照明により提供するので、平面ではなく多段に重ねた棚の上で栽培することで、面積当たりの収容率を高めることが行われている。 A plant factory can stably harvest crops of constant quality regardless of the season by artificially controlling the plant cultivation environment. In plant factories, light is provided by illumination without relying on sunlight, so plants are cultivated on multi-tiered shelves instead of on a flat surface to increase the accommodation rate per area.

近年、温室や屋内での植物栽培において、その植物や生育状態に応じて栽培環境を管理することが一般的に行われている。このような栽培方法の一つとして、施肥量、灌水量を管理することに加えて、閉鎖的な空間で温度、湿度、光量をも管理した植物工場が提案されている。この植物工場では、栽培温度、湿度を管理し、さらに光量や日長に関しても人工光源によって適切に管理する。このような植物工場では栽培環境を人工的に制御することで、季節を選ばず一定品質の作物を安定的に収穫することができる。また、人工光源の採用により多段の栽培棚で3次元的な高密度栽培が可能となる。これにより、単位面積あたりの収容率を高めることができる。 BACKGROUND ART In recent years, in plant cultivation in greenhouses and indoors, it is common practice to manage the cultivation environment according to the plants and their growing conditions. As one of such cultivation methods, a plant factory has been proposed in which, in addition to controlling the amount of fertilization and irrigation, the temperature, humidity, and amount of light are also controlled in a closed space. In this plant factory, the cultivation temperature and humidity are controlled, and the amount of light and the length of day are appropriately controlled by artificial light sources. In such a plant factory, by artificially controlling the cultivation environment, it is possible to stably harvest crops of constant quality regardless of the season. In addition, the use of artificial light sources enables three-dimensional high-density cultivation with multi-stage cultivation racks. Thereby, the accommodation rate per unit area can be improved.

例えば特許文献1には、アルミニウム部材を利用して、栽培棚を多段に設置するために垂直に伸びる支柱を四隅に加えて長さ方向の複数個所に設けられた垂直支柱を有して垂直枠を為し、支柱と支柱との間に棚を渡し、その上に栽培容器を載置する載置棚で植物栽培装置を構成する例が提案されている。 For example, Patent Document 1 discloses a vertical frame that uses an aluminum member and has vertical posts provided at a plurality of locations in the length direction in addition to vertical posts at the four corners in order to install cultivation shelves in multiple stages. Thus, an example is proposed in which a shelf is provided between the support posts, and a plant cultivation apparatus is configured by a mounting shelf on which a cultivation container is placed.

しかしながら、単に多段にするだけでは面積当たりの収容率の向上は不十分であり、経済的にはさらに収容率を向上して植物工場全体の経済性を向上させることが求められた。 However, merely increasing the number of stages is insufficient to improve the accommodation rate per area, and from an economic point of view, it has been required to further improve the accommodation rate to improve the economic efficiency of the plant factory as a whole.

例えば特許文献1では、四隅に支柱を据えることで水平方向と奥行方向に重複して部材を配して強度を保つ構造となっている。さらに、垂直方向でも、横部材に加えて複数段の受けレールが設けられている。水平/垂直/奥行方向にそれぞれ重複して多数の部材を使用することにより強度は確保できるものの、その分だけ支柱や部材が占める領域が多く、植物の栽培容器に割り当てられる空間に制限があり、面積当たりの収容率の向上には限界があった。 For example, in Japanese Patent Laid-Open No. 2002-100000, a structure is provided in which struts are installed at the four corners to maintain strength by arranging overlapping members in the horizontal direction and the depth direction. Furthermore, in the vertical direction, a plurality of stages of receiving rails are provided in addition to the cross members. Although strength can be ensured by using multiple members that overlap in the horizontal, vertical, and depth directions, the area occupied by the pillars and members is correspondingly large, and the space allocated to the plant cultivation container is limited. There was a limit to improving the accommodation rate per area.

そこでこの発明は、植物工場で用いる植物栽培装置において、面積当たりの収容率をさらに向上させることを目的とする。 Accordingly, an object of the present invention is to further improve the accommodation rate per area in a plant cultivation apparatus used in a plant factory.

This invention
A plurality of vertical struts, each facing vertically and lined up on a straight line,
a horizontal strut that is fixed to the vertical struts, spans between the vertical struts, is oriented horizontally, and is provided in a plurality of stages in the vertical direction;
a beam member extending in both lateral directions perpendicular to the length direction of the lateral strut from the lateral strut;
a water gutter having a space opened upward so that a cultivation container can be stored, which is placed on each of the left and right sides of the horizontal support along the horizontal support on the beam material;
The above problems are solved by a plant cultivation device having

すなわち、四隅に支柱を持つ櫓構造ではなく、一直線上に並ぶ縦支柱と、その間を渡して固定される横支柱から梁材が延ばされた上に栽培容器が並ぶので、両横方向の占有面積が支柱一本分とそれに伴う部位の分だけ削減することができ、面積当たりの収容率が大きく向上した植物栽培装置となった。 In other words, instead of a turret structure with pillars at the four corners, vertical pillars lined up in a straight line and horizontal pillars fixed across the pillars extend the beams from which the cultivation containers are lined up, so both horizontal pillars can be occupied. The area of the plant cultivation apparatus can be reduced by the area corresponding to one support and the part associated with it, and the accommodation rate per area is greatly improved.

また、この発明にかかる植物栽培装置は、下から二段目以降の前記水樋が下方側の一部に通水孔を有し、前記通水孔から下方に位置する別の前記水樋へ、落下より減速させて水を伝える伝水路を有する構造を採用できる。各段の前記水樋からの排水管を設けようとすると、その分だけ上下方向の高さを余分に必要とする。そこで、各段の前記水樋で排水すべき水を、伝水路をつたって下方にある別の前記水樋へ送り込み、最下段の前記水樋からのみ排水管に繋げることができるようにすると、従来は最下段以外の各段に設ける必要があった排水管の分だけ上下方向高さに必要な体積を削減することができる。例えば従来であれば4段分までしか収容できなかった空間に、5段分まで収容するといったことが可能になる。 Further, in the plant cultivation apparatus according to the present invention, the water gutter on the second and subsequent stages from the bottom has a water passage hole in a part of the lower side, and from the water passage hole to the other water gutter located below. , a structure having a transmission channel for transmitting water by decelerating it from falling can be adopted. If an attempt is made to install drain pipes from the water troughs of each stage, an extra vertical height is required accordingly. Therefore, if the water to be drained by the water troughs of each stage is sent to the other water troughs located below along the transmission channel, and it is possible to connect to the drain pipe only from the water troughs of the lowest stage, It is possible to reduce the volume required for the height in the vertical direction by the amount of the drainage pipes that had to be provided in each stage other than the lowest stage in the past. For example, it is possible to accommodate up to five stages in a space that could only accommodate up to four stages in the past.

また、この発明にかかる植物栽培装置は、その植物栽培装置を設置する設置面に接して前記両横方向に回転可能な車輪と、前記車輪を回転させる駆動機構とを有する構造を採用できる。車輪を有し可動式にすることで、設置後に同型の植物栽培装置との間をできるだけ詰めて設置することができるので、複数台を設置する際の面積当たりの収容率を高めることができる。 In addition, the plant cultivation apparatus according to the present invention can employ a structure having wheels rotatable in both lateral directions in contact with an installation surface on which the plant cultivation apparatus is installed, and a drive mechanism for rotating the wheels. By having wheels and making it movable, it is possible to install it with the same type of plant cultivation device as close as possible after installation, so that the accommodation rate per area when installing a plurality of units can be increased.

さらに、上記の車輪と駆動機構を有する構造に加えて、設置箇所の天井に、前記両横方向に配したレール内を移動するローラと、前記ローラから下方に配された天井リングとを設けておく。この天井リングを、最上段の前記縦支柱又は横支柱に対して直接的に又は間接的に拘束した拘束具を有する構造を採用できる。可動式にするだけでは転倒しやすくなってしまうが、可動する方向に沿って配したレール上を稼働できる天井リングに拘束させることで、地震などの際に転倒する危険性を大幅に抑制できる。 Furthermore, in addition to the structure having the above wheels and drive mechanism, the ceiling of the installation location is provided with rollers that move in the rails arranged in both lateral directions, and a ceiling ring arranged below the rollers. back. A structure having a restraining device that directly or indirectly restrains the ceiling ring with respect to the uppermost vertical support or horizontal support can be employed. Just making it movable makes it prone to overturning, but by restraining it with a ceiling ring that can move on rails arranged along the direction of movement, the risk of overturning in the event of an earthquake or the like can be greatly reduced.

また、この発明にかかる植物栽培装置は、前記栽培容器に給水する給水機構として、前記縦支柱に並行する縦給水管と、前記縦給水管から分岐して各段の前記横支柱に並行して前記水樋の間に配された横給水管と、前記横給水管から前記栽培容器へ給水する個別給水管とを有する構成を採用できる。前記横支柱を前記水樋の間に格納することで、上下方向の占有幅が給水機構によって広がらず、上下方向に格納できる段数を増やすことができる。 Further, in the plant cultivating apparatus according to the present invention, as a water supply mechanism for supplying water to the cultivation container, a vertical water supply pipe parallel to the vertical support and a It is possible to employ a configuration having horizontal water supply pipes arranged between the water troughs and individual water supply pipes for supplying water from the horizontal water supply pipes to the cultivation containers. By storing the horizontal struts between the water troughs, the occupied width in the vertical direction is not increased by the water supply mechanism, and the number of steps that can be stored in the vertical direction can be increased.

この発明にかかる植物栽培装置により、面積当たりに収容できる栽培容器の数を従来の櫓構造の植物栽培装置に比べて飛躍的に増加させることができる。これにより、植物工場における面積当たりの収容率及び作物の生産効率を高めることができる。 The plant cultivating apparatus according to the present invention can dramatically increase the number of cultivating containers that can be accommodated per unit area compared to conventional turret-structured plant cultivating apparatuses. As a result, the accommodation rate per area and the production efficiency of crops in the plant factory can be increased.

以下、この発明について具体的な実施形態とともに詳細に説明する。この発明は、面積当たりの収容率を高めた植物栽培装置10である。 Hereinafter, the present invention will be described in detail along with specific embodiments. The present invention is a plant cultivation device 10 with an increased accommodation rate per area.

この発明にかかる植物栽培装置の実施形態例の全体図を図1(a)及び(b)に示す。図1(a)は横方向から見た全体側面図、図1(b)は長さ方向から見た正面図である。なお、本説明において図1(b)における左右方向を横方向という。 An overall view of an embodiment of a plant cultivation apparatus according to the present invention is shown in FIGS. 1(a) and 1(b). FIG. 1(a) is an overall side view seen from the lateral direction, and FIG. 1(b) is a front view seen from the length direction. In addition, in this description, the left-right direction in FIG.1(b) is called a horizontal direction.

この植物栽培装置10の基本骨格は、それぞれが鉛直方向に向き、一直線上に並ぶ複数本の縦支柱11と、縦支柱11に対して固定され、縦支柱11,11同士の間を渡し水平方向に向き、上下方向に複数段設けられた横支柱12(12a~12f)とからなる。縦支柱11が向く前記鉛直方向は図1(a)(b)の上下方向であり、横支柱12は図1(a)の左右方向で示される水平方向に向く。ここでは、一直線上に3本の縦支柱11が並んだ実施形態を示しているが、2本でもよいし、4本以上でもよい。ただし、縦支柱11の本数が増えると、その部分は後述する栽培容器16を設置できないために面積当たりの収容率が減少してしまうので、縦支柱11の数は強度上必要最低限に抑えることが望ましい。 The basic framework of the plant cultivation apparatus 10 includes a plurality of vertical posts 11 aligned in a vertical direction, and fixed to the vertical posts 11 to bridge between the vertical posts 11 and 11 in the horizontal direction. It consists of lateral struts 12 (12a to 12f) provided in multiple stages in the vertical direction. The vertical direction in which the vertical support 11 faces is the vertical direction in FIGS. 1(a) and 1(b), and the horizontal support 12 is oriented in the horizontal direction shown in the horizontal direction in FIG. 1(a). Here, an embodiment in which three vertical struts 11 are aligned on a straight line is shown, but the number may be two, or four or more. However, if the number of vertical struts 11 increases, the cultivation container 16, which will be described later, cannot be installed in that portion, and the accommodation rate per area decreases. is desirable.

上記の縦支柱11及び横支柱12を構成するそれぞれの支柱は、一定の長さを持つ、強度の高い材質のものであれば良く、例えば、金属製で中空状の円筒管、角パイプや、H型鋼を使用することができる。その中でも、工事現場で足場資材として利用される一般的な単管を用いると、強度及びコストの点で特に望ましい。 Each of the pillars constituting the vertical pillar 11 and the horizontal pillar 12 may be made of a material having a certain length and high strength. H-beam steel can be used. Among them, it is particularly desirable to use a general single pipe that is used as a scaffolding material at construction sites in terms of strength and cost.

上記の縦支柱11及び横支柱12との間の接点では、クランプ13により上下左右に交錯しながら接するように固定する。このクランプ13により縦支柱11と横支柱12とを固定した形態を、図2の斜視図及び図3の拡大図に示す。このクランプ13としても、工事現場で足場資材の固定に利用される一般的なクランプを用いると、強度及びコストの点で特に望ましい。また、支柱の形状に応じて、上記のクランプの代わりに同様に支柱同士を固定できる部材を適宜利用できる。 At the points of contact between the vertical struts 11 and the horizontal struts 12, clamps 13 are used to fix the vertical and horizontal struts so that they are in contact with each other. A configuration in which the vertical support 11 and the horizontal support 12 are fixed by the clamp 13 is shown in the perspective view of FIG. 2 and the enlarged view of FIG. As the clamps 13, it is particularly desirable to use general clamps used for fixing scaffolding materials at construction sites in terms of strength and cost. Also, depending on the shape of the pillars, a member capable of fixing the pillars to each other can be appropriately used in place of the clamp described above.

横支柱12(12a~12f)には、間隔を空けて梁材14が複数個取り付けられる。梁材14は横支柱12の長さ方向に対して垂直な両横方向に延ばされている。この両横方向とは図1(b)における左右方向にあたる。梁材を横支柱12に取り付ける形態としては、特に限定されないが、この実施形態では横支柱12を囲むUボルトクランプ27が下に突起を延ばしており、その突起に対して下方から梁材14を固定している。横支柱12の下側から両横方向に梁材14の両梁が延びる構造となっている。この梁材14には後述する水樋15及び栽培容器16の重量が集中するため、金属製で強固な材料で形成されることが望ましい。 A plurality of beam members 14 are attached to the horizontal struts 12 (12a to 12f) at intervals. The beams 14 extend in both lateral directions perpendicular to the longitudinal direction of the lateral struts 12 . The two lateral directions correspond to the left and right directions in FIG. 1(b). Although there are no particular restrictions on the form in which the beams are attached to the lateral struts 12, in this embodiment, the U-bolt clamps 27 surrounding the lateral struts 12 have projections extending downward, and the beams 14 are attached to the projections from below. Fixed. It has a structure in which both beams of the beam member 14 extend in both lateral directions from the lower side of the lateral strut 12 . Since the weight of the water gutter 15 and the cultivation container 16, which will be described later, concentrates on the beam member 14, it is desirable that the beam member 14 be made of a strong metal material.

この横支柱12から両横方向にそれぞれ複数本延ばされた梁材14の上に、横支柱12に沿って水樋15が載せられる。図1(a)では水樋15が3本の梁材14に支えられている。また、図1(b)では横支柱12の横方向として左右両方に梁材14が延ばされており、左右それぞれに水樋15を載せた実施形態を示している。ただし、本発明としてはこれに限らず、左右いずれかの方向に延びる梁材を、上下互い違いに設けてその上に水樋15を設置する実施形態でもよい。水樋15は横支柱12の長さ方向に長い方形又は半円筒形で、内部に後述する栽培容器16を格納できるように上向きに開放された空間を有するように形成されている。なお、格納される際に、栽培容器16が脱落しなければ、栽培容器16の全体が収まっていなくても良い。また、水樋15は内部に流された水をまとめて排水できるように内部に傾斜ができるように形成されているか、または傾斜を有するように配されている。この実施形態では傾斜を有するように両横方向に傾くように配されている。水樋15はできるだけ軽量で、かつ水を通さないことが必要である。このため水樋15はプラスチック材料で形成されていると好ましい。なお、軽量かつ水を通さなければ、金属でも木材であってもよい。 A water gutter 15 is placed along the horizontal support 12 on a plurality of beams 14 extending in both horizontal directions from the horizontal support 12 . In FIG. 1( a ), the water gutter 15 is supported by three beams 14 . In addition, FIG. 1(b) shows an embodiment in which beams 14 are extended in both the left and right sides of the horizontal support 12, and water troughs 15 are placed on the left and right sides, respectively. However, the present invention is not limited to this, and may be an embodiment in which beam members extending in either the left or right direction are provided alternately in the vertical direction and the gutter 15 is installed thereon. The water gutter 15 has a square or semi-cylindrical shape elongated in the longitudinal direction of the horizontal strut 12, and is formed to have an upwardly open space in which a cultivation container 16, which will be described later, can be stored. In addition, if the cultivation container 16 does not fall off when stored, the entire cultivation container 16 does not have to be stored. In addition, the water gutter 15 is formed so as to have a slope inside or is arranged to have a slope so that the water that has flowed inside can be drained collectively. In this embodiment, it is arranged to be inclined in both lateral directions so as to have an inclination. The water gutter 15 should be as light as possible and impervious to water. Therefore, it is preferable that the water gutter 15 is made of a plastic material. Metal or wood may be used as long as it is lightweight and impervious to water.

水樋15を両横方向に傾斜させている構造の拡大図を図4に示す。梁材14の左右両側に勾配曲げ金具28が取り付けられており、これが水樋15の両横方向の側面を支えて、傾斜させた状態で固定している。この勾配曲げ金具28の斜視図を図5に示す。勾配曲げ金具28は、梁材14の上部に乗る天面28aと、天面28aから直角に下方へ折れ曲がった固定面28bと、天面28aから上方に跳ね上がった傾斜面28dを有する。固定面28bには固定穴28cが空けられ、梁材14の固定穴に対してネジ留めすることで勾配曲げ金具28の全体を固定できる。天面28aと傾斜面28dとの為す角度は、植える作物の条件に応じて適宜設定するとよい。具体的には100度以上125度以下程度に設定するとよい。これにより、栽培容器の土などの内容物の脱落を防ぎ、かつ、作業時に視認性・作業性が向上することができる。 FIG. 4 shows an enlarged view of the structure in which the water gutter 15 is tilted in both lateral directions. Angle bending metal fittings 28 are attached to both left and right sides of the beam 14, which support both lateral side surfaces of the water gutter 15 and fix it in an inclined state. A perspective view of this slope bending fitting 28 is shown in FIG. The sloped bending fitting 28 has a top surface 28a on which the top surface of the beam member 14 rests, a fixed surface 28b bent downward at right angles from the top surface 28a, and an inclined surface 28d that rises upward from the top surface 28a. A fixing hole 28c is formed in the fixing surface 28b, and the entire slope bending fitting 28 can be fixed by screwing it into the fixing hole of the beam member 14. As shown in FIG. The angle formed by the top surface 28a and the inclined surface 28d may be appropriately set according to the conditions of the crops to be planted. Specifically, it should be set to about 100 degrees or more and 125 degrees or less. As a result, contents such as soil in the cultivation container can be prevented from falling off, and visibility and workability can be improved during work.

一方、水樋15の中央方向側の下方角は、横支柱12(図4では12xと表示)を囲んで梁材14を支えるUボルトクランプ27の上側に乗って支えられている。上記の天面28aと傾斜面28dとの為す角度は、水樋15の中央方向側の下方角がUボルトクランプ27の上に乗せられたときに、水樋15の両横方向側の側面の角度に傾斜面28dが沿う角度であると好ましい。 On the other hand, the lower corner of the water gutter 15 on the central direction side is supported on the upper side of the U-bolt clamp 27 that surrounds the horizontal strut 12 (indicated by 12x in FIG. 4) and supports the beam member 14 . The angle formed by the top surface 28a and the inclined surface 28d is such that when the downward angle of the central direction side of the water gutter 15 is put on the U-bolt clamp 27, the side surfaces of both lateral sides of the water gutter 15 It is preferable that the angle is an angle along which the inclined surface 28d follows.

水樋15の内側には作物を育成する栽培容器16が設けられる。図に示す実施形態ではポット状の栽培容器16を水樋15の長さ方向に並べているが、形状はこれに限定されず、例えば水樋15に沿った長尺形状の栽培容器を並べていてもよい。ただし、水樋15の内部に植えられる作物の株数や収穫量ができるだけ多くなるように、間隔を空けずに栽培容器16を詰めておけることが望ましい。それにより、面積当たりの収容率を高めることができる。栽培容器16も軽量であることが望ましく、プラスチック材料で形成されていると好ましい。栽培容器16の中は土やスポンジ、不織布などの、作物の種や苗などを固定できる内容物が詰められている。これらの内容物は水を保持できることが望ましい。一方で、栽培容器16の下方には、余分な水を排水できる排水口(図示せず)が設けられていると好ましい。排水口から排出された水は、水樋15に集められて排水される。 A cultivation container 16 for growing crops is provided inside the water gutter 15 . In the illustrated embodiment, the pot-shaped cultivation containers 16 are arranged in the length direction of the water gutter 15, but the shape is not limited to this. good. However, it is desirable that the cultivation containers 16 can be packed with no space between them so that the number of crops planted inside the water gutter 15 and the yield can be maximized. Thereby, the accommodation rate per area can be improved. The cultivation container 16 is also desirably lightweight and is preferably made of a plastic material. The cultivation container 16 is filled with contents such as soil, sponge, non-woven fabric, etc., to which seeds and seedlings of crops can be fixed. It is desirable that these contents be able to retain water. On the other hand, it is preferable that a drainage port (not shown) for draining excess water is provided below the cultivation container 16 . Water discharged from the drain port is collected in a gutter 15 and drained.

以上の構成により、横支柱12(12b~12f)ごとの各段に、左右両横に水樋15が配され、この水樋15の内部に栽培容器16が並べられた構造が並ぶ。従来の櫓構造に比べて、横支柱12を挟んで水樋15が並んでいるだけで四隅や外周を支柱などで囲まれることがなく、水平方向の占有面積を削減し、面積当たりの収容率を高めた構造を実現している。このような構造を上下方向に複数段重ねて、さらに面積当たりの収容率を数倍にしている。 With the above configuration, water troughs 15 are arranged on both left and right sides of each stage of each of the horizontal struts 12 (12b to 12f), and a structure in which cultivation containers 16 are arranged inside the water troughs 15 is arranged. Compared to the conventional turret structure, the horizontal occupied area is reduced and the accommodation rate per area is achieved without surrounding the four corners or the outer periphery with the support by simply arranging the water gutter 15 with the horizontal support 12 interposed therebetween. It realizes a structure that enhances By stacking a plurality of such structures in the vertical direction, the storage rate per area is increased several times.

個々の栽培容器16への給水機構の例を図6の斜視図を用いて説明する。縦支柱11と並行に、縦給水管18が設けてある。縦給水管18には下方から水が供給される。縦給水管18からは横支柱12(12b~12f)ごとに設けられた各段について、それぞれ横給水管19(19a~19e)が分岐している。横給水管19は各段の横支柱12に並行して水樋15,15の間に配されている。水樋15は上記の通り両横方向に傾いている分、中央側が広く空いており、ここに横給水管19を通すことで、スペースを有効活用し、各段に必要な高さを節約できる。横給水管19の上部からは個別給水管17が分岐しており、この個別給水管17を介して個々の栽培容器16へ給水する。また、縦給水管18から分岐したそれぞれの横給水管19(19a~19e)には弁を操作するコック22が設けてあり、その段の水樋15及び栽培容器16への給水が一時的に不要になった場合にはコック22を操作して給水を停止する。 An example of a water supply mechanism to each cultivation container 16 will be described with reference to the perspective view of FIG. A vertical water supply pipe 18 is provided in parallel with the vertical strut 11 . Water is supplied to the vertical water supply pipe 18 from below. Horizontal water supply pipes 19 (19a to 19e) branch off from the vertical water supply pipe 18 for each stage provided for each of the horizontal struts 12 (12b to 12f). The horizontal water supply pipe 19 is arranged between the water gutters 15, 15 in parallel with the horizontal struts 12 of each stage. Since the water gutter 15 is tilted in both lateral directions as described above, the center side is wide open, and by passing the horizontal water supply pipe 19 through this space, the space can be effectively used and the height required for each stage can be saved. . An individual water supply pipe 17 is branched from the upper portion of the horizontal water supply pipe 19 , and water is supplied to each cultivation container 16 via the individual water supply pipe 17 . In addition, each horizontal water supply pipe 19 (19a to 19e) branched from the vertical water supply pipe 18 is provided with a cock 22 for operating a valve, and the water supply to the water gutter 15 and the cultivation container 16 of that stage is temporarily supplied. When it becomes unnecessary, the cock 22 is operated to stop water supply.

なお、栽培容器16への給水機構は上記の形態に限られるものではなく、個別給水管17の先端形状が変更されたものであったり、横給水管19が水樋15の上方にあって散水により給水するものであったり、特に限定されない。ただし、スペースの有効活用の点からは、水樋15、15の間に横給水管19を配するのが特に好ましい。また、コック22の弁が電磁弁であってもよいし、その電磁弁を電子的に制御するシステムを別途備えていてもよい。 In addition, the water supply mechanism to the cultivation container 16 is not limited to the above-described form, and the tip shape of the individual water supply pipe 17 is changed, or the horizontal water supply pipe 19 is above the water gutter 15 and sprinkles water. It is not particularly limited. However, from the point of view of effective use of space, it is particularly preferable to arrange the horizontal water supply pipe 19 between the water gutters 15,15. Also, the valve of the cock 22 may be an electromagnetic valve, or a separate system for electronically controlling the electromagnetic valve may be provided.

次に、個々の栽培容器16からの排水機構の例を、図4を参照して説明する。栽培容器16は植木鉢などのように下方に排水口が空けられており、栽培容器16で余分となった水が水樋15に落ちて集められる。水樋15は両横方向へ傾けられているので、集められた水はこの傾きによって底部両横方向側へと集まる。この底部両横方向側のように最下部に位置することになる水樋15の下方側の一部に、水を排出する通水孔25を空ける。設置した際に水が集まる最下部となる位置であれば水樋15の底面に限られず、傾けた際に下側となる側面であってもよい。さらに、この通水孔25は開放せずに、孔を通して下方に位置する別の水樋15の上まで到達する伝水路23を取り付けてある。伝水路23は、水が自由落下するよりも流速を制限させて水を下側へと伝えるものである。排水の流速を制限せずに下方に位置する別の水樋15へ落下させると跳ね返って、植物や機器などに排水がかかる恐れがある。流速を制限することでこのような事態を抑制し、植物の汚染や、機器の故障などを防止することができる。スペースを省略するためには、水平方向へ延びたりせず、真下へ向けられていることが望ましい。例えば、流速を制限する突起物を内部に備えたホースなどが挙げられる。また、傾斜を有する螺旋状の管によって最終的に真下へ向かわせるものでもよい。図に示す実施形態では、伝水路23として、耐水性のある鎖を用いる例を示す。通水孔25を通る排水は、排水管などでまとめる必要なく、伝水路23を伝って下方に位置する別の水樋15で集めることができる。このため、各段の水樋15からの排水を集めるための排水用配管を各段の下部に設けなくてよくなり、上下方向に必要となるスペースを削減できる。なお、最下段の拡大図である図7に示すように、最下段の水樋15から下に延ばされた伝水路23は、最下段にのみ設けられた排水管24の中へ到達されており、最上段の水樋15から最下段の水樋15までの全ての排水が、排水管24一本で集めて排水可能となる。 Next, an example of a drainage mechanism from each cultivation container 16 will be described with reference to FIG. The cultivating container 16 has a drainage port at the bottom like a flowerpot, and excess water in the cultivating container 16 falls into a gutter 15 and is collected. Since the water gutter 15 is tilted in both lateral directions, the collected water gathers on both lateral sides of the bottom due to this inclination. A water passage hole 25 for discharging water is formed in a portion of the lower side of the water gutter 15 which is to be positioned at the lowest portion, such as both lateral sides of the bottom. It is not limited to the bottom surface of the water gutter 15 as long as it is the lowest position where water collects when installed, and may be the side surface that is the lower side when tilted. Furthermore, this water flow hole 25 is not opened, and a water transmission path 23 is attached to reach the top of another water gutter 15 located below through the hole. The transmission channel 23 is for transmitting the water downward by restricting the flow velocity rather than allowing the water to freely fall. If the water is dropped into another water gutter 15 located below without restricting the flow velocity of the water, the water may rebound and splash on plants, equipment, and the like. By limiting the flow velocity, such a situation can be suppressed, and contamination of plants and failure of equipment can be prevented. In order to save space, it is desirable that it is not extended horizontally but directly downward. For example, there is a hose having a protrusion inside to limit the flow velocity. Alternatively, a helical tube having an inclination may be used to direct the tube to the bottom. In the illustrated embodiment, an example of using a water-resistant chain as the transmission channel 23 is shown. Drainage that passes through the water passage hole 25 can be collected by another water gutter 15 located below along the water transmission path 23 without the need to collect it with a drainage pipe or the like. Therefore, it is not necessary to provide drainage pipes for collecting the drainage from the water gutter 15 of each stage at the bottom of each stage, and the space required in the vertical direction can be reduced. In addition, as shown in FIG. 7, which is an enlarged view of the lowest stage, the transmission channel 23 extending downward from the water gutter 15 at the lowest stage reaches the drain pipe 24 provided only at the lowest stage. All of the drainage from the uppermost water gutter 15 to the lowermost water gutter 15 can be collected and drained by one drainage pipe 24.例文帳に追加

個々の栽培容器16で育成する作物を照らす照明機構としては、図2の最上段に示すように、梁材14の下方側に、横支柱12aに沿って配された長尺状の照明材20が利用できる。照明材20の構成としては、LEDを用いると、波長や波長ごとの光量などを任意に選択できるとともに、使用する電力量も最小限にとどめることができるので好ましい。 As a lighting mechanism for illuminating the crops grown in the individual cultivation containers 16, as shown in the uppermost part of FIG. is available. As for the configuration of the lighting material 20, it is preferable to use LEDs because the wavelength and the amount of light for each wavelength can be arbitrarily selected, and the power consumption can be minimized.

この発明にかかる植物栽培装置10は、全体を動かせるようにするため、設置面に接して両横方向に回転可能な車輪36と、車輪36を回転させる駆動機構とを有する。全体を動かせると、栽培に関する作業を終えた後、隣接する植物栽培装置10との間のスペースを詰めることが容易にできる。これにより、多数の植物栽培装置10を併用する際の収容率を高めることが容易にできる。 The plant cultivation apparatus 10 according to the present invention has wheels 36 that are rotatable in both lateral directions in contact with the installation surface and a drive mechanism that rotates the wheels 36 in order to move the whole. If the entire device can be moved, the space between adjacent plant cultivating devices 10 can be easily reduced after finishing work related to cultivating. Thereby, it is possible to easily increase the accommodation rate when using a large number of plant cultivation devices 10 together.

駆動機構と車輪36の構成例を、装置下部を拡大した図7を参照して説明する。車輪36は四隅に配されている。これらの車輪36は、各段の栽培容器16への通常の作業では植物栽培装置10が倒れないように支えられる位置に配されていると好ましい。これらの車輪は装置の底部のフレームとなる装置台部37に対して固定されている。装置台部37の上面には、縦支柱11を支えて固定する支柱固定部38が設けられており、縦支柱11を装置台部37に対して固定している。車輪36の少なくとも一つに対して、手動で回転力を与えるハンドル31が装置台部37の上方に取り付けてある。ハンドル31は手動で回すものであるため、大人の作業者の手が立ったまま届く高さに設けられていると好ましい。ハンドル31を回転した回転力は、ベルトチェーン34,34を介して、車輪36に隣接する回転軸35を回転させる。なお、ベルトチェーン34,34の間に、ベルトチェーン34に対して噛み合い回転される中継軸33を設けてある。中継軸33及び回転軸35ともに、装置台部37に対して回転可能に取り付けられてある。ハンドル31が回されたことに従って回転軸35が回転されると、さらにベルトチェーンを介して車輪36が回転され、植物栽培装置10を両横方向に移動させることができる。なお、伝達機構はベルトチェーンに限定されるものではなく、その他の回転駆動機構を選択してよい。 A configuration example of the drive mechanism and the wheels 36 will be described with reference to FIG. Wheels 36 are arranged at the four corners. These wheels 36 are preferably arranged at a position where they are supported so that the plant cultivating apparatus 10 does not topple during normal work on the cultivating containers 16 on each stage. These wheels are fixed to a device base 37 which forms the bottom frame of the device. A column fixing portion 38 for supporting and fixing the vertical column 11 is provided on the upper surface of the device base portion 37 to fix the vertical column 11 to the device base portion 37 . A handle 31 for manually applying a rotational force to at least one of the wheels 36 is attached above the apparatus base portion 37 . Since the handle 31 is to be turned manually, it is preferably provided at a height that an adult operator can reach while standing. A rotational force that rotates the handle 31 rotates a rotating shaft 35 adjacent to a wheel 36 via belt chains 34 , 34 . Between the belt chains 34 , 34 is provided a relay shaft 33 that engages with and rotates with the belt chain 34 . Both the relay shaft 33 and the rotary shaft 35 are rotatably attached to the apparatus base portion 37 . When the rotating shaft 35 is rotated according to the rotation of the handle 31, the wheels 36 are further rotated through the belt chain, and the plant cultivation device 10 can be moved in both lateral directions. In addition, the transmission mechanism is not limited to the belt chain, and other rotation driving mechanisms may be selected.

さらに、この発明にかかる植物栽培装置10は、転倒防止機構を有すると好ましい。上記の車輪36があることで移動させやすくなる半面、奥行方向の部材が使用されていないこともあり、高速な移動や地震などにより大きな揺れが両横方向に掛けられた場合、転倒しやすくなってしまうため、その危険性を低減するための機構である。この転倒防止機構の例を図8の斜視図及び図9の天井部断面図とともに説明する。植物栽培装置10を設置する箇所の天井Sに、両横方向に配したレール43を設けてある。レール43の天井S裏には、振動を受けた際に植物栽培装置10の荷重を支えられるように、レール固定具45が設けてある。レール43の内部には、レール43に沿って移動するローラ44が入れ込まれており、ローラ44からは下方に天井リング41がぶら下げられてある。天井リング41と、最上段の縦支柱11又は横支柱12aとの間を、直接的に又は間接的に拘束具で繋いで拘束する。図では拘束具として転倒防止チェーン42を用いた例を示す。直接的にとは、天井リング41を通した拘束具を、縦支柱11や横支柱12aに直接引っ掛けて外れないようにすることである。間接的にとは、天井リング41を通した拘束具を、縦支柱11や横支柱12aに別途取り付けて固定した金具などの付属品に引っ掛けて外れないようにすることである。横支柱12aであれば横支柱12aの下側をくぐらせることで直接的に拘束しやすい。縦支柱11であれば例えば上端に拡幅された部位を持つ抜け止めを設けてその抜け止めより下に拘束具を引っ掛けることで、縦支柱11に直接的に拘束できる。間接的に取り付ける場合は、拘束具の形態に応じて適宜様々な金具を選択できる。いずれの形態であっても、高速な移動や地震などにより大きな揺れが起きて、両横方向に植物栽培装置10が揺れ動いても、横支柱12aに転倒防止チェーン42で繋げられた天井リング41が、レール43内を移動するローラ44を動かし、揺れを吸収する。これにより、植物栽培装置10が転倒する危険性を抑制できる。 Furthermore, the plant cultivation device 10 according to the present invention preferably has an overturn prevention mechanism. While the wheels 36 make it easier to move, the fact that no members in the depth direction are used makes it more likely to tip over when large shaking is applied in both lateral directions due to high-speed movement or earthquakes. This is a mechanism to reduce the risk of An example of this overturn prevention mechanism will be described with reference to the perspective view of FIG. 8 and the cross-sectional view of the ceiling portion of FIG. Rails 43 arranged in both lateral directions are provided on the ceiling S at the place where the plant cultivation device 10 is installed. A rail fixture 45 is provided behind the ceiling S of the rail 43 so as to support the load of the plant cultivation device 10 when subjected to vibration. A roller 44 that moves along the rail 43 is inserted inside the rail 43 , and a ceiling ring 41 is hung downward from the roller 44 . The ceiling ring 41 and the uppermost vertical support 11 or horizontal support 12a are directly or indirectly connected and restrained by a restraint tool. The figure shows an example in which a fall prevention chain 42 is used as a restraint. The term “directly” means that the restraining tool passed through the ceiling ring 41 is directly hooked to the vertical support 11 or the horizontal support 12a so as not to come off. "Indirectly" means that the restraint through which the ceiling ring 41 is passed is hooked to an accessory such as a metal fitting separately attached and fixed to the vertical support 11 or the horizontal support 12a so as not to come off. In the case of the horizontal strut 12a, it is easy to directly restrain by passing under the horizontal strut 12a. In the case of the vertical support 11, for example, by providing a retainer having a widened portion at the upper end and hooking a restraining tool below the retainer, the vertical support 11 can be directly restrained. In the case of indirect attachment, various fittings can be appropriately selected according to the form of the restraint. In either form, even if the plant cultivating apparatus 10 shakes in both lateral directions due to large shaking caused by high-speed movement or an earthquake, the ceiling ring 41 connected to the lateral strut 12a with the overturning prevention chain 42 will remain intact. , move the rollers 44 moving in the rails 43 to absorb the shaking. Thereby, the danger that the plant cultivation apparatus 10 will topple over can be suppressed.

本発明の植物栽培装置として、図1に示す形態の植物栽培装置を製造した。長さ8mで24株分の栽培装置を収容した水樋を、両横方向に2本並べた。両横方向の占有幅は550mmとなった。また、各段には排水管を設けず、各段の水樋からは下の段への排水を伝わせる伝水チェーンを設けることで、一段あたりの上下方向高さを圧縮し、段数は5段分を収容することができた。 As a plant cultivation apparatus of the present invention, a plant cultivation apparatus having the configuration shown in FIG. 1 was manufactured. Two water troughs having a length of 8 m and accommodating 24 strains of the cultivation apparatus were arranged in both horizontal directions. The occupied width in both lateral directions was 550 mm. In addition, each level does not have a drainage pipe, but instead a water transmission chain is installed to convey the water from the water gutter of each level to the level below. It was able to accommodate the steps.

一方、従来の櫓型で四隅に支柱を有する植物栽培装置に、上記と同じ長さ8mで24株分の栽培装置を収容した水樋を、一段あたり2列並べた。両横方向の占有幅は600mmであり、支柱がある分だけ両横方向の占有面積は本発明の植物栽培装置に比べて広がってしまった。 On the other hand, in a conventional turret-shaped plant cultivation apparatus having support posts at four corners, water troughs having the same length of 8 m and accommodating 24 plants were arranged in two rows per stage. The occupied width in both lateral directions is 600 mm, and the occupied area in both lateral directions is wider than that of the plant cultivation apparatus of the present invention due to the support.

また、従来の植物栽培装置では、それぞれの水樋の下部に水平方向へ延びる排水管を取り付けてあり、端部に設けた縦排水管に集約して排水する機構を採用した。このため、縦排水管の分、一段あたりの上下方向高さは本発明の植物栽培装置より高くなり、全体としては同じ高さの中に、4段分のみ収容することができた。 In addition, in the conventional plant cultivation apparatus, a drain pipe extending in the horizontal direction is attached to the lower part of each water gutter, and a mechanism is adopted in which water is collected and drained in a vertical drain pipe provided at the end. For this reason, the height in the vertical direction per stage is higher than that of the plant cultivation apparatus of the present invention due to the vertical drainage pipe, and only four stages can be accommodated in the same height as a whole.
