Description

根切り機構、植物栽培装置、及び水耕栽培装置Root cutting mechanism, plant cultivation device, and hydroponic cultivation device
　本発明は、人工的に植物を栽培する装置、及び当該栽培されている植物の根を切る根切機構に関する。 The present invention relates to an apparatus for artificially cultivating a plant, and a root cutting mechanism for cutting roots of the cultivated plant.
　近年、植物を人工的に植物工場で栽培する技術が開発されている。現在のところ、植物工場で栽培される植物としては、葉菜類の栽培がほとんどである。このような葉菜類の植物は、その葉や実などが収穫され、根は利用されず捨てられる場合が多い。今後、植物工場で栽培可能な品種が広がることが期待されている。 In recent years, techniques for artificially growing plants in plant factories have been developed. At present, most plants grown in plant factories are leafy vegetables. Such leaf vegetable plants are often discarded without using their roots and harvesting their leaves and fruits. It is expected that varieties that can be cultivated in plant factories will be expanded in the future.
　ここで、植物工場では、コスト効率が最大の課題となるため、栽培する植物としては、残渣の少ない作物（根なども全て利用できるもの）が求められている。 Here, in plant factories, cost efficiency is the biggest issue, so crops with few residues (those that can use all roots, etc.) are required as plants to be cultivated.
　一例として、ニンニクは、一般的には、鱗茎を食用として収穫することが多いが、その茎や葉の部分も野菜として利用されている。 As an example, garlic is generally often harvested as edible bulbs, but the stems and leaves are also used as vegetables.
　また、特に、ニンニクは、根の部分にも様々な医療用途に適用が可能といわれるアホエンが豊富に含まれている。このように、ニンニクは、残渣の少ない作物である。 In particular, garlic is rich in ajoene, which is said to be applicable to various medical uses in the root part. Thus, garlic is a crop with little residue.
　特許文献１には、水耕栽培システムにより、ニンニクの根を効率よく栽培する栽培方法が提案されている。 Patent Document 1 proposes a cultivation method for efficiently cultivating garlic roots using a hydroponic cultivation system.
　また、特許文献２には、植物の根を収穫するための根切り装置が提案されている。特許文献２には、発芽した植物が通過できる網目を持つネット枠と，ネット枠の上面または下面、若しくは複数ネット枠の間にカッターが通過することによって、ネットより下の部分を切断する根きり装置が開示されている。 Also, Patent Document 2 proposes a root cutting device for harvesting plant roots. In Patent Document 2, a net frame having a mesh through which a germinated plant can pass, and an upper or lower surface of the net frame, or a root that cuts a portion below the net when a cutter passes between a plurality of net frames. An apparatus is disclosed.

　ニンニク等、植物の根は、一度切り取っても再生する。このため、水耕栽培で、植物の根を、効率よく収穫するために、植物の根の部分を繰り返し収穫するような装置が必要である。 Roots of plants such as garlic are regenerated even if they are cut once. For this reason, in order to efficiently harvest plant roots in hydroponics, an apparatus that repeatedly harvests plant root portions is required.
　特許文献１に記載の水耕栽培システムには、水耕栽培を行なっているニンニクの根を収穫するための構成が備えられていない。このため、特許文献１に記載の水耕栽培システムでは、ニンニクの根を収穫する場合、水耕栽培システムから、水耕栽培を行なっているニンニクを取り外してから、当該ニンニクの根を収穫する必要がある。このように、特許文献１の記載の水耕栽培システムでは、根を収穫するための効率が悪いという課題が生じる。 The hydroponics system described in Patent Document 1 is not provided with a configuration for harvesting garlic roots that are hydroponically cultivated. For this reason, in the hydroponic cultivation system described in Patent Document 1, when harvesting garlic roots, it is necessary to remove the garlic that is hydroponically cultivated from the hydroponic cultivation system and then harvest the garlic roots. There is. Thus, the hydroponic cultivation system described in Patent Document 1 has a problem that the efficiency for harvesting roots is poor.
　また、特許文献２に記載の根きり装置は、根を利用することを前提としておらず、根切り後に栽培を続けるような栽培方法が考慮されていない。このため、特許文献２に記載の根きり装置では、植物体の根を全て切り取ってしまうため、根切り後の植物の生育に大きなダメージを与えてしまうことになる。 Also, the rooting device described in Patent Document 2 does not assume the use of roots, and does not consider a cultivation method that continues cultivation after root cutting. For this reason, since the root cutting apparatus described in Patent Document 2 cuts off all the roots of the plant body, it causes a great damage to the growth of the plant after the root cutting.
　本発明は、上記の問題点を解決するためになされたもので、その目的は、植物栽培装置で栽培されている植物の生育に及ぼす影響を抑制し、かつ、効率よく上記植物の根を収穫する。 The present invention has been made to solve the above-mentioned problems, and its purpose is to suppress the influence on the growth of the plant cultivated by the plant cultivation apparatus and to efficiently harvest the root of the plant.

Thereby, the root of the plant which a support stand supports can be cut out by pushing down the above-mentioned movable part.
　このため、上記支持台が支持する植物の根を切り取るために、当該植物を支持台から取り出す必要は無く、上記支持台に植物を載置したまま当該植物の根を切り取ることができるので、効率よく、植物の根を収穫することができる。 For this reason, in order to cut off the root of the plant supported by the support base, it is not necessary to take out the plant from the support base, and the root of the plant can be cut out while the plant is placed on the support base. Well, you can harvest plant roots.
　上記構成によると、上記切取部は、上記可動部が押下されることで、上記植物の根の一部を残して、当該植物の根を切り取る。このように、上記植物の根を全て切り取らず、一部を残して、上記植物の根を切り取ることで、上記植物の生育に及ぼす影響を抑制して、上記植物の根を収穫することができる。 According to the above configuration, the cutting unit cuts off the root of the plant leaving a part of the root of the plant when the movable unit is pressed. Thus, the root of the plant can be harvested by suppressing the influence on the growth of the plant by cutting off the root of the plant without cutting all the roots of the plant and leaving a part of the roots. .
　このように、上記構成によると、植物栽培装置で栽培されている植物の生育に及ぼす影響を抑制し、かつ、効率よく上記植物の根を収穫することができる。 Thus, according to the above configuration, it is possible to suppress the influence on the growth of the plant cultivated by the plant cultivation apparatus and to efficiently harvest the root of the plant.
　本発明は、植物の栽培を行なう植物栽培装置に取り付け可能であり、当該植物の根を切るための根切り機構で、上記植物を支持する支持台に、押下されることが可能に配された可動部と、上記可動部の先端に配され、当該可動部が押下されることで、一部を残して上記植物の根を切り取る切取部とを備えている。 The present invention can be attached to a plant cultivating apparatus for cultivating a plant, and is arranged so that it can be pressed to a support base that supports the plant by a root cutting mechanism for cutting the root of the plant. The movable part is provided at the tip of the movable part, and a cutout part that cuts off the root of the plant leaving a part when the movable part is pressed down.

　〔実施の形態１〕
　（根切り機構を備えた水耕栽培装置の構成）
　以下、本発明の根切り機構の第１の実施形態について説明する。 [Embodiment 1]
(Configuration of hydroponic cultivation device with root cutting mechanism)
Hereinafter, a first embodiment of the root cutting mechanism of the present invention will be described.
　図１の（ａ）は、本実施の形態に係る水耕栽培装置１の構成を表す断面図であり、（ｂ）は（ａ）の平面図である。 (A) of FIG. 1 is sectional drawing showing the structure of the hydroponic cultivation apparatus 1 which concerns on this Embodiment, (b) is a top view of (a).
　水耕栽培装置（植物栽培装置）１は、水耕栽培によって、植物の栽培を行なう植物栽培装置である。本実施の形態では、ニンニク（植物）３０を栽培しているものとして説明する。水耕栽培装置１は、培養液タンク２と、培養液３と、棚板（支持台）４と、根切り機構１０とを主に備えている。 Hydroponic cultivation apparatus (plant cultivation apparatus) 1 is a plant cultivation apparatus that grows plants by hydroponics. In the present embodiment, it is assumed that garlic (plant) 30 is cultivated. The hydroponic cultivation apparatus 1 mainly includes a culture solution tank 2, a culture solution 3, a shelf board (support stand) 4, and a root cutting mechanism 10.
　根切り機構１０は、植物の栽培を行なう水耕栽培装置１に取り付け可能であり、水耕栽培装置１で栽培している植物の根を切るためのものである。根切り機構１０は、水耕栽培装置１が栽培している植物の根を全て切り取らず、一部を残すようにして当該植物の根を切り取る。 The root cutting mechanism 10 can be attached to the hydroponic cultivation apparatus 1 for cultivating plants, and is for cutting the roots of the plants cultivated by the hydroponic cultivation apparatus 1. The root cutting mechanism 10 cuts the roots of the plant so as not to cut all the roots of the plant cultivated by the hydroponic cultivation device 1 but to leave a part.
　根切り機構１０は、棚板４に、押下されることが可能に配されたカッター（可動部）１１と、カッター１１の先端に配され、カッター１１が押下されることで一部を残してニンニク３０の根３２を切り取るための刃（切取部）１２と、棚板４に配され、カッター１１を押下されることが可能に棚板４と接続するストッパー（接続部材）１３と、弾性部材であるバネ１４と、カッター１１を下限まで押下したとき刃１７と当接する表面を含む切取台１５とを備えている。換言すると、棚板４に対するカッター１１の相対位置のうち、刃１７が切取台１５の表面と当接する位置が、カッター１１の下限である。 The root cutting mechanism 10 is arranged on the shelf plate 4 so that it can be pressed (movable part) 11, and is arranged at the tip of the cutter 11. A blade (cutting portion) 12 for cutting the root 32 of the garlic 30, a stopper (connecting member) 13 that is arranged on the shelf board 4 and is connected to the shelf board 4 so that the cutter 11 can be pressed down, and an elastic member And a cutting table 15 including a surface that comes into contact with the blade 17 when the cutter 11 is pressed down to the lower limit. In other words, of the relative positions of the cutter 11 with respect to the shelf plate 4, the position where the blade 17 contacts the surface of the cutting table 15 is the lower limit of the cutter 11.
　培養液タンク２は、培養液３を収容するための水槽である。培養液タンク２の材質は特に限定されず、プラスチック、コンクリート等などからなる。培養液３は、栽培する植物に応じて必要な養分が加えられた液体の肥料であり、一般的に使用されている液体肥料を用いることができる。 The culture solution tank 2 is a water tank for storing the culture solution 3. The material of the culture solution tank 2 is not particularly limited, and is made of plastic, concrete, or the like. The culture solution 3 is a liquid fertilizer to which necessary nutrients are added according to the plant to be cultivated, and a commonly used liquid fertilizer can be used.
　棚板４は、水耕栽培装置１で栽培する植物を支持し、また、後述するように、押下されることが可能に配されたカッター１１を支持する支持台でもある。ニンニク３０は、この棚板４に載置されて栽培されている。 The shelf board 4 supports a plant that is cultivated by the hydroponic cultivation apparatus 1 and is also a support base that supports a cutter 11 that can be pressed as described later. The garlic 30 is placed and cultivated on the shelf board 4.
　棚板４の材質は、栽培する植物を安定して載置することができ、また、カッター１１を押下することができるように接続することができるものであればよく、発砲スチロール等からなる。 The material of the shelf board 4 may be any material that can stably place the plant to be cultivated and can be connected so that the cutter 11 can be pressed, and is made of foamed polystyrene.
　なお、棚板４の材質としては、上述したように、発泡スチロールのように軽量な材質が好ましい。特に、棚板４は、高圧縮で強度を高めた発泡スチロールで構成されていることが好ましい。これにより、棚板４の強度を高めることができるので、カッター４を押下する力が加わっても破損することを防止することができる。 In addition, as a material of the shelf board 4, as mentioned above, a lightweight material like a polystyrene foam is preferable. In particular, the shelf board 4 is preferably made of foamed polystyrene having high compression and increased strength. Thereby, since the intensity | strength of the shelf board 4 can be raised, even if the force which presses down the cutter 4 is added, it can prevent damaging.
　棚板４には、載置されているニンニク３０の鱗茎（植物）３１を支持することができ、ニンニク３０の根３２を通過させることができる程度の大きさの開口部７が設けられている。棚板４に設けられる開口部７は、栽培する植物に応じて大きさが決定されるものである。本実施の形態のように、ニンニク３０を栽培する場合、開口部７の直径は、例えば、１～５ｃｍ程度が適当である。 The shelf plate 4 is provided with an opening 7 that can support a bulb (plant) 31 of the garlic 30 that is placed and can pass the root 32 of the garlic 30. . The size of the opening 7 provided in the shelf board 4 is determined according to the plant to be cultivated. When the garlic 30 is cultivated as in this embodiment, the diameter of the opening 7 is suitably about 1 to 5 cm, for example.
　棚板４は、培養液３の液面と、ニンニク３０の根３２の生え際との間に、空間が設けられる程度の高さに設置されている。このようにニンニク３０の根３２の生え際に空間を設けることで、ニンニク３０の根３２の生え際のうち、空気に露出されている部分が酸素を吸収し易くなる。これにより、ニンニク３０の成長を促進することができる。 The shelf board 4 is installed at such a height that a space is provided between the liquid level of the culture solution 3 and the root of the root 32 of the garlic 30. Thus, by providing a space at the root of the garlic root 32, the portion exposed to the air in the root of the garlic root 32 easily absorbs oxygen. Thereby, the growth of the garlic 30 can be promoted.
　また、棚板４には、カッター１１を挿設するための複数の開口部１７が設けられている。開口部１７は、刃１２の形状に対応するような形状となるように棚板４に設けられている。後述するように、本実施の形態では、カッター１１は複数設けられているので、複数のカッター１１に対応して、開口部１７も棚板に複数設けられている。 Further, the shelf plate 4 is provided with a plurality of openings 17 for inserting the cutters 11. The opening 17 is provided in the shelf board 4 so as to have a shape corresponding to the shape of the blade 12. As will be described later, in the present embodiment, since a plurality of cutters 11 are provided, a plurality of openings 17 are also provided on the shelf plate corresponding to the plurality of cutters 11.
　また、棚板４に、ニンニク３０の鱗茎３１をそのまま載置することで、ニンニク３０を発根させてもよいが、水耕栽培装置１では、棚板４に載置したニンニク３０の鱗茎３１を、フィルム５、及びビーズ６からなる保護部材で、発根部分が露出するように覆っている。これにより、ニンニク３０の鱗茎３１の乾燥を防ぐことができる。フィルム５は、例えば、合成樹脂等からなり、ビーズ６は、例えば、発泡スチロール等からなる。 Further, the garlic 30 may be rooted by placing the bulb 31 of the garlic 30 on the shelf 4 as it is, but in the hydroponic cultivation apparatus 1, the bulb 31 of the garlic 30 placed on the shelf 4. Is covered with a protective member composed of the film 5 and the beads 6 so that the root portion is exposed. Thereby, drying of the bulb 31 of the garlic 30 can be prevented. The film 5 is made of, for example, a synthetic resin, and the beads 6 are made of, for example, expanded polystyrene.
　また、棚板４に、栽培する植物の根が通過する程度の開口部を設けた培地を設け、当該培地に、上記栽培する植物を載置するようにしてもよい。 Alternatively, a medium provided with an opening that allows passage of the roots of the plant to be cultivated may be provided on the shelf board 4, and the plant to be cultivated may be placed on the medium.
　カッター１１は、棚板４を貫通して配されるものであり、水耕栽培装置１で栽培される植物のうち、棚板４より下の部分を切り取るためのものである。 The cutter 11 is arranged so as to penetrate the shelf board 4, and is for cutting a portion below the shelf board 4 among the plants cultivated by the hydroponic cultivation apparatus 1.
　カッター１１は、複数のカッター１１ａ・１１ｂ・１１ｃ・１１ｄからなる。複数のカッター１１ａ・１１ｂ・１１ｃ・１１ｄは、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配されており、それぞれ独立して、押下されることが可能である。 The cutter 11 includes a plurality of cutters 11a, 11b, 11c, and 11d. The plurality of cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 supported by the shelf board 4, and can be pressed independently.
　カッター１１ａ・１１ｂ・１１ｃ・１１ｄを平面視したとき、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、円形状となるように、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配されている。水耕栽培装置１では、ニンニク３０の鱗茎３１を覆うフィルム５の外側の周囲を囲って、カッター１１ａ・１１ｂ・１１ｃ・１１ｄが配されている。 When the cutters 11a, 11b, 11c, and 11d are viewed in plan, the cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 supported by the shelf board 4 so as to be circular. Yes. In the hydroponic cultivation apparatus 1, cutters 11 a, 11 b, 11 c, and 11 d are arranged surrounding the outer periphery of the film 5 that covers the bulb 31 of the garlic 30.
　カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、平面視したとき、円形状を４分割した形状として構成されている。 The cutters 11a, 11b, 11c, and 11d are configured as a shape obtained by dividing a circular shape into four when viewed in plan.
　棚板４には、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配するカッター１１ａ・１１ｂ・１１ｃ・１１ｄをそれぞれ挿設するための開口部１７として、複数の開口部１７ａ・１７ｂ・１７ｃ・１７ｄが設けられている。そして、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのそれぞれは、開口部１７ａ・１７ｂ・１７ｃ・１７ｄのそれぞれに挿設されている。つまり、開口部１７ａ・１７ｂ・１７ｃ・１７ｄも、４分割された円形状となるように、平面視したときにニンニク３０の鱗茎３１の周囲を囲って、棚板４に設けられている。 The shelf 4 includes a plurality of openings 17a, 11a, 11b, 11c, and 11d as openings 17 into which the cutters 11a, 11b, 11c, and 11d that are arranged around the bulb 31 of the garlic 30 supported by the shelf 4 are inserted. 17b, 17c and 17d are provided. The cutters 11a, 11b, 11c, and 11d are inserted into the openings 17a, 17b, 17c, and 17d, respectively. That is, the openings 17a, 17b, 17c, and 17d are also provided on the shelf board 4 so as to surround the bulb 31 of the garlic 30 when viewed in plan so as to have a circular shape divided into four.
　図２を用いて、棚板４に接続されたカッター１１の構成について説明する。図２は、水耕栽培装置１のカッター１１の構成を説明する図である。なお、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、いずれも同様の構成であるので、図２では、カッター１１ａの構成について説明する。 The configuration of the cutter 11 connected to the shelf board 4 will be described with reference to FIG. FIG. 2 is a diagram illustrating the configuration of the cutter 11 of the hydroponic cultivation apparatus 1. Since the cutters 11a, 11b, 11c, and 11d have the same configuration, the configuration of the cutter 11a will be described with reference to FIG.
　カッター１１ａは、棚板４に設けられた開口部１７ａを貫通するように配されており、カッター１１ａの一方の端部（押下部）は、棚板４の表面（ニンニク３０の鱗茎３１が載置されている側の面）と、弾性部材であるバネ１４によって接続されている。 The cutter 11a is arranged so as to pass through the opening 17a provided in the shelf board 4, and one end (pressing part) of the cutter 11a is placed on the surface of the shelf board 4 (the bulb 31 of the garlic 30 is mounted). And the spring 14 which is an elastic member.
　カッター１１ａは、棚板４の裏面（培養液３と対向する側の面）と、ストッパー１３によって接続されている。このように、カッター１１ａにバネ１４と、ストッパー１３を設けることで操作性を向上させることができる。 The cutter 11 a is connected to the back surface of the shelf plate 4 (the surface facing the culture solution 3) by a stopper 13. As described above, the operability can be improved by providing the cutter 11 a with the spring 14 and the stopper 13.
　カッター１１ａの他方の端部（先端部）には、カッター１１ａが押下されることで、一部を残してニンニク３０の根３２を切り取る刃１２が配されている。 The other end (tip portion) of the cutter 11a is provided with a blade 12 that cuts off the root 32 of the garlic 30 by leaving the cutter 11a pressed.
　このように、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、それぞれ独立して、押下されることが可能に棚板４に配されている。このため、ニンニク３０の根３２のうち、切断したい箇所に対応するカッターを押下することが可能である。 Thus, the cutters 11a, 11b, 11c, and 11d are arranged on the shelf plate 4 so that they can be pressed independently. For this reason, it is possible to press down the cutter corresponding to the location to be cut among the roots 32 of the garlic 30.
　また、図１の（ａ）に示すように、切取台１５は、ニンニク３０の下方に位置するように、培養液タンク２内に設置されている。 Further, as shown in FIG. 1A, the cutoff table 15 is installed in the culture solution tank 2 so as to be positioned below the garlic 30.
　切取台１５の材質は、例えば、ポリプロピレンなどのプラスチック等を用いることができる。 The material of the cutoff table 15 can be, for example, plastic such as polypropylene.
　切取台１５は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを、下限まで押下したとき、カッター１１ａ・１１ｂ・１１ｃ・１１ｄに配された刃１２と当接する表面を含むものである。 When the cutters 11a, 11b, 11c, and 11d are pressed down to the lower limit, the cutoff table 15 includes a surface that comes into contact with the blades 12 disposed on the cutters 11a, 11b, 11c, and 11d.
　切取台１５は、上方から下方にかけて、上記表面間の距離が、次第に広がっている。これにより、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを押下したとき、当該カッター（例えばカッター１１ａ）に配された刃１２を、切取台１５の表面に当接させることができる。従って、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを押下することで、ニンニク３０の根３２を収穫することができる。具体的には、本実施の形態では、切取台１５の形状は円錐台であり、その側面が、上記表面である。 The distance between the surfaces of the cutoff table 15 gradually increases from the top to the bottom. Thereby, when the cutters 11a, 11b, 11c, and 11d are pressed, the blade 12 disposed on the cutter (for example, the cutter 11a) can be brought into contact with the surface of the cutting table 15. Therefore, the root 32 of the garlic 30 can be harvested by pressing the cutters 11a, 11b, 11c, and 11d. Specifically, in the present embodiment, the shape of the cutoff table 15 is a truncated cone, and its side surface is the surface.
　（根切りについて）
　次に、図３、４を用いて、根を切り取ることについて説明する。 (About root cutting)
Next, with reference to FIGS. 3 and 4, cutting the root will be described.
　図３は、水耕栽培装置１で栽培している植物の根を収穫することを説明する図である。 FIG. 3 is a diagram illustrating that the roots of plants cultivated by the hydroponic cultivation apparatus 1 are harvested.
　なお、図３を用いて、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのうち、カッター１１ａを押下する場合について説明する。 In addition, the case where the cutter 11a is pushed down among the cutters 11a, 11b, 11c, and 11d will be described with reference to FIG.
　切取台１５は、その側面が、カッター１１ａを下限まで押下したとき、カッター１１ａに配された刃１２と当接するように配されている。刃１２の刃先は、切取台１５の側面と適合するように形成されている。 The cutting table 15 is arranged such that its side surface comes into contact with the blade 12 arranged on the cutter 11a when the cutter 11a is pressed down to the lower limit. The cutting edge of the blade 12 is formed so as to be compatible with the side surface of the cutoff table 15.
　円錐台である切取台１５は、ニンニク３０の下方に位置するように、培養液タンク２内に設置されている。 The cutting table 15 which is a truncated cone is installed in the culture solution tank 2 so as to be located below the garlic 30.
　このため、ニンニク３０が棚板４に載置されると、ニンニク３０の根３２は、生育に伴って、切取台１５の側面に沿って伸びることになる。このように、ニンニク３０の根３２が、切取台１５の側面に沿って伸びるので、ニンニク３０の根３２が、刃１２と、切取台１５の側面との間に配されることになる。そして、図３の矢印に示すように、ニンニク３０の根３２のうち、収穫したい箇所に該当するカッター１１ａを押下する。 For this reason, when the garlic 30 is placed on the shelf board 4, the roots 32 of the garlic 30 will extend along the side surface of the cutting table 15 as it grows. Thus, since the root 32 of the garlic 30 extends along the side surface of the cutting table 15, the root 32 of the garlic 30 is arranged between the blade 12 and the side surface of the cutting table 15. Then, as shown by the arrow in FIG. 3, the cutter 11 a corresponding to the portion to be harvested is pressed among the roots 32 of the garlic 30.
　図４は、複数のカッター１１のうち、一部が押下された水耕栽培装置１を表す断面図である。 FIG. 4 is a cross-sectional view showing the hydroponic cultivation apparatus 1 in which some of the cutters 11 are pressed.
　図４の水耕栽培装置では、カッター１１ａが押下されている。カッター１１ｃは押下されていない。図４に示すように、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのうち、押下されたカッター１１ａに配された刃１２によって、ニンニク３０の根３２は、切取台１５の側面に押圧されて切断される。 In the hydroponic cultivation apparatus in FIG. 4, the cutter 11a is pressed. The cutter 11c is not pressed. As shown in FIG. 4, among the cutters 11a, 11b, 11c, and 11d, the root 32 of the garlic 30 is pressed against the side surface of the cutting table 15 and cut by the blade 12 disposed on the pressed cutter 11a. .
　上述した特許文献２の根切り装置では、植物の根を横方向に切断する構成なので、当該植物の根は全て切断されることになる。一方、本実施の形態に係る根切り機構１０によると、カッター１１を横方向（水平方向）でははく、縦方向（鉛直方向）に押入れる構成であるので、ニンニク３０の根３２を全て切り取らず、部分的に残すことが可能となる。 Since the root cutting device of Patent Document 2 described above is configured to cut the root of the plant in the lateral direction, all the roots of the plant are cut. On the other hand, according to the root cutting mechanism 10 according to the present embodiment, since the cutter 11 is pushed in the vertical direction (vertical direction) instead of in the horizontal direction (horizontal direction), all the roots 32 of the garlic 30 are cut off. Instead, it can be partially left.
　このように、根切り機構１０の複数のカッター１１ａ・１１ｂ・１１ｃ・１１ｄは、棚板４が支持するニンニク３０の周囲を囲って配されており、それぞれ独立して、押下されることが可能である。このため、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのうち、押下されたカッター１１ａの先端に配されている刃１２によってだけニンニク３０の根３２を切り取り、押下されていないカッター１１ｂ・１１ｃ・１１ｄに配されている刃１２によっては、ニンニク３０の根３２は切り取られない。すなわち、ニンニク３０の根３２は、押下されたカッター１１ａに配された刃１２によってだけ収穫され、その他の部分は残される。 As described above, the plurality of cutters 11a, 11b, 11c, and 11d of the root cutting mechanism 10 are arranged so as to surround the garlic 30 supported by the shelf board 4, and can be pressed independently. It is. Therefore, among the cutters 11a, 11b, 11c, and 11d, the root 32 of the garlic 30 is cut only by the blade 12 that is disposed at the tip of the pressed cutter 11a, and the cutters 11b, 11c, and 11d are not pressed. Depending on the blade 12, the root 32 of the garlic 30 is not cut off. That is, the root 32 of the garlic 30 is harvested only by the blade 12 disposed on the pressed cutter 11a, and the other parts are left.
　従って、根切り機構１０によると、ニンニク３０の生育に及ぼす影響を抑制して、ニンニク３０の根３２を収穫することができる。 Therefore, according to the root cutting mechanism 10, the influence on the growth of the garlic 30 can be suppressed and the root 32 of the garlic 30 can be harvested.
　また、根切り機構１０では、カッター１１ａを、下限まで押下したとき、カッター１１ａに配された刃１２と当接する側面を含む切取台１５を備えているので、ニンニク３０の根３２を確実に切り取ることができ、効率よく、ニンニク３０の根３２を収穫することができる。 Further, since the root cutting mechanism 10 includes the cutting base 15 including the side surface that comes into contact with the blade 12 disposed on the cutter 11a when the cutter 11a is pressed down to the lower limit, the root 32 of the garlic 30 is surely cut off. The roots 32 of garlic 30 can be harvested efficiently.
　また、図１の（ｂ）に示したように、水耕耕栽培装置１では、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを平面視したとき、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、円形状となるように、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配されている。 Moreover, as shown to (b) of FIG. 1, in hydroponic cultivation apparatus 1, when cutter 11a * 11b * 11c * 11d is planarly viewed, cutter 11a * 11b * 11c * 11d becomes circular shape. Thus, it arrange | positions surrounding the circumference | surroundings of the bulb 31 of the garlic 30 which the shelf board 4 supports.
　このように、円錐台形である切取台１５の形状に合せて、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを、ニンニク３０の鱗茎３１の周囲を囲って配することで、カッター１１ａ・１１ｂ・１１ｃ・１１ｄの何れを押下しても、刃１２と切取台１５の側面とを当接させることができ、確実に、ニンニク３０の根３２を切り取ることができる。 Thus, the cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 in accordance with the shape of the truncated cone 15 that is a truncated cone. Can be brought into contact with the side surface of the cutting table 15, and the root 32 of the garlic 30 can be cut out reliably.
　（切取台の形状とカッターの配置）
　切取台１５は、下記の理由から錐形であることが好ましい。 (Cut-off stand shape and cutter arrangement)
The cutoff table 15 is preferably conical for the following reasons.
　まず、切取台１５の形状が、錐形でない場合について図５の（ａ）（ｂ）を用いて説明する。 First, the case where the shape of the cutoff table 15 is not a conical shape will be described with reference to FIGS.
　図５の（ａ）（ｂ）は、断面形状が長方形である切取台を備えた水耕栽培装置を表す図であり、（ａ）は、側面が、押下された刃と当接しない切取台を備えた水耕栽培装置を表す図であり、（ｂ）は、側面が、押下された刃と当接する切取台を備えた水耕栽培装置を表す図である。 (A) (b) of Drawing 5 is a figure showing the hydroponic cultivation apparatus provided with the cutting stand whose section shape is a rectangle, and (a) is a cutting stand whose side does not contact a pressed blade. (B) is a figure showing the hydroponic cultivation apparatus provided with the cutting stand which a side surface contacts with the pressed blade.
　図５の（ａ）の切取台１１５は、断面が長方形である。換言すると、切取台１１５の形状は柱状となっている。 5A has a rectangular cross section. In other words, the shape of the cutoff table 115 is a columnar shape.
　また、切取台１１５は、カッター１１が押下されたとしても、カッター１１の先端に配された刃１２と、切取台１１５の側面とが当接しないような円形状となっている。換言すると、平面視したとき、切取台１１５の上面および下面のそれぞれの面積は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄによって構成される円の面積より小さい。 Further, the cutting table 115 has a circular shape so that the blade 12 disposed at the tip of the cutter 11 does not contact the side surface of the cutting table 115 even when the cutter 11 is pressed. In other words, when viewed in plan, the areas of the upper surface and the lower surface of the cutoff table 115 are smaller than the area of the circle formed by the cutters 11a, 11b, 11c, and 11d.
　このため、切取台１１５の側面に沿って伸びたニンニク３０の根３２を切断しようと、カッター１１を押下したとしても、当該カッター１１に配された刃１２と、切取台１１５の側面とによって、ニンニク３０の根３２を押圧することができず、ほとんどニンニク３０の根３２を切断することができない。 For this reason, even if the cutter 11 is pressed to cut the root 32 of the garlic 30 extending along the side surface of the cutting table 115, the blade 12 disposed on the cutter 11 and the side surface of the cutting table 115 The root 32 of the garlic 30 cannot be pressed, and the root 32 of the garlic 30 can hardly be cut.
　また、図５の（ｂ）の切取台１２５は、断面が長方形である。換言すると、切取台１２５の形状は柱状となっている。 Further, the cutting table 125 in FIG. 5B has a rectangular cross section. In other words, the shape of the cutoff table 125 is columnar.
　また、切取台１２５は、カッター１１が押下されると、カッター１１の先端に配された刃１２と、切取台１２５の側面とが当接するような円形状となっている。換言すると、平面視したとき、切取台１１５の上面および下面の面積は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄによって構成される円の面積より大きい。 The cutting table 125 has a circular shape such that when the cutter 11 is pressed, the blade 12 disposed at the tip of the cutter 11 and the side surface of the cutting table 125 come into contact with each other. In other words, when viewed in plan, the area of the upper surface and the lower surface of the cutting table 115 is larger than the area of the circle formed by the cutters 11a, 11b, 11c, and 11d.
　このため、ニンニク３０の根３２は、水平方向に配された切取台１２５の上面上で入り組んで伸びることになる。このため、押下されたカッター１１の刃１２によって切断されるニンニク３０の根３２は、切り取り位置や長さがばらばらとなり、商品としての価値を低下させることになる。 For this reason, the roots 32 of the garlic 30 are intricately extended on the upper surface of the cutting table 125 arranged in the horizontal direction. For this reason, the roots 32 of the garlic 30 cut by the pressed blades 12 of the cutter 11 vary in cutting position and length, and the value as a product is reduced.
　また、ニンニク３０の根３２は、切取台１２５の上面上で入り組んで伸びるので、カッター１１のうち、例えばカッター１１ａなど、必ずしも、押下したカッター１１ａの刃１２の下方に存在しているとは限らない。このため、収穫の効率が低下することになる。 Moreover, since the root 32 of the garlic 30 extends in an intricate manner on the upper surface of the cutoff table 125, the cutter 11 does not necessarily exist below the blade 12 of the pressed cutter 11 a, such as the cutter 11 a. Absent. For this reason, the efficiency of harvesting falls.
　一方、図１の（ａ）（ｂ）、図３で説明したように、根切り機構１０が備える切取台１５は、錐台形状をしている。 On the other hand, as described in FIGS. 1A and 1B and FIG. 3, the cutoff table 15 provided in the root cutting mechanism 10 has a frustum shape.
　具体的には、平面視したとき、切取台１５の上面の面積は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄによって構成される円の面積より小さく、切取台１５の下面の面積は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄによって構成される円の面積より大きい。 Specifically, when viewed in plan, the area of the upper surface of the cutting table 15 is smaller than the area of the circle constituted by the cutters 11a, 11b, 11c, and 11d, and the area of the lower surface of the cutting table 15 is determined by the cutters 11a and 11b. -It is larger than the area of the circle constituted by 11c and 11d.
　また、平面視したときに、カッター１１ａ・１１ｂ・１１ｃ・１１ｄが円形状に配されていることに合せて、切取台１５は、円錐台形状をしている。 Further, when viewed in plan, the cutting table 15 has a truncated cone shape in accordance with the circular arrangement of the cutters 11a, 11b, 11c, and 11d.
　これにより、切取台１５は、カッター１１を、下限まで押下したとき、カッター１１に配された刃１２と当接するように側面が構成されている。 Thus, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 11 when the cutter 11 is pressed down to the lower limit.
　このため、切取台１５の側面に沿って伸びたニンニク３０の根３２を、押下されたカッター１１ａに配された刃１２によって切断することができるので、長さを揃えてニンニク３０の根３２を切断することができ、商品としての価値を低下させることなく、より確実に、ニンニク３０の根３２を収穫することができる。 For this reason, since the root 32 of the garlic 30 extended along the side surface of the cutting stand 15 can be cut | disconnected by the blade 12 distribute | arranged to the pressed cutter 11a, the length 32 is arranged and the root 32 of the garlic 30 is removed. The roots 32 of the garlic 30 can be harvested more reliably without reducing the value as a product.
　ここで、切取台１５は、錐形であればよく、円錐台形状に限らず、円錐形であってもよい。さらに、図６の（ａ）～（ｃ）に示すように、切取台１５は、多角錐台であってもよい。 Here, the cutting table 15 may be a cone shape, and is not limited to a truncated cone shape, and may be a cone shape. Further, as shown in FIGS. 6A to 6C, the cutting table 15 may be a polygonal frustum.
　図６の（ａ）～（ｃ）は、根切り機構を備える水耕栽培装置を表す平面図であり、（ａ）は三角錐台の切取台を備える水耕栽培装置を表し、（ｂ）は四角錐台の切取台を備える水耕栽培装置を表し、（ｃ）は五角錐台の切取台を備える水耕栽培装置を表す図である。 6 (a) to 6 (c) are plan views showing a hydroponic cultivation apparatus provided with a root cutting mechanism, (a) showing a hydroponic cultivation apparatus equipped with a triangular pyramid cutout stand, and (b). Represents a hydroponic cultivation apparatus equipped with a truncated pyramid cutout, and (c) represents a hydroponic cultivation apparatus equipped with a pentagonal truncated cutout.
　図６の（ａ）に示すように、切取台２２は、三角錐台の形状を有している。また、カッター２１は、複数のカッター２１ａ・２１ｂ・２１ｃからなり、平面視したとき、三角形となるように、棚板４に挿設されている。 As shown in FIG. 6A, the cutoff table 22 has a triangular frustum shape. The cutter 21 includes a plurality of cutters 21a, 21b, and 21c, and is inserted into the shelf board 4 so as to be triangular when viewed in plan.
　このように、切取台２２は、カッター２１を、下限まで押下したとき、カッター２１に配された刃１２と当接するように側面が構成されている。 Thus, the side surface of the cutting table 22 is configured so as to come into contact with the blade 12 disposed on the cutter 21 when the cutter 21 is pushed down to the lower limit.
　図６の（ｂ）に示すように、切取台２４は、四角錐台の形状を有している。また、カッター２３は、複数のカッター２３ａ・２３ｂ・２３ｃ・２３ｄからなり、平面視したとき、四角形となるように、棚板４に挿設されている。 As shown in FIG. 6B, the cutoff table 24 has a quadrangular pyramid shape. The cutter 23 includes a plurality of cutters 23a, 23b, 23c, and 23d, and is inserted into the shelf plate 4 so as to be square when viewed in plan.
　このように、切取台２４は、カッター２３を、下限まで押下したとき、カッター２３に配された刃１２と当接するように側面が構成されている。 Thus, the side surface of the cutting table 24 is configured to come into contact with the blade 12 disposed on the cutter 23 when the cutter 23 is pressed down to the lower limit.
　図６の（ｃ）に示すように、切取台２６は、五角錐台の形状を有している。また、カッター２５は、複数のカッター２５ａ・２５ｂ・２５ｃ・２５ｄ・２５ｅからなり、平面視したとき、五角形となるように、棚板４に挿設されている。 As shown in FIG. 6C, the cutoff table 26 has a pentagonal pyramid shape. The cutter 25 includes a plurality of cutters 25a, 25b, 25c, 25d, and 25e, and is inserted into the shelf plate 4 so as to be a pentagon when viewed in plan.
　このように、切取台２６は、カッター２５を、下限まで押下したとき、カッター２５に配された刃１２と当接するように側面が構成されている。 Thus, the side surface of the cutting table 26 is configured to come into contact with the blade 12 disposed on the cutter 25 when the cutter 25 is pressed down to the lower limit.
　さらに、切取台２２、切取台２４、切取台２６は、それぞれ、三角錐、四角錐、五角錐であってもよいし、六角錐又は六角錐台以上の多角錐、多角錐台であってもよい。 Further, the cutting table 22, the cutting table 24, and the cutting table 26 may be a triangular pyramid, a quadrangular pyramid, and a pentagonal pyramid, respectively, and may be a hexagonal pyramid or a polygonal pyramid or a polygonal pyramid that is higher than the hexagonal pyramid. Good.
　このように、カッター２１ａ・２１ｂ・２１ｃ、２２ａ・２２ｂ・２２ｃ、２３ａ・２３ｂ・２３ｃそれぞれを平面視したとき、カッター２１ａ・２１ｂ・２１ｃ、２２ａ・２２ｂ・２２ｃ、２３ａ・２３ｂ・２３ｃは、多角形状となるように、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配されている。 Thus, when the cutters 21a, 21b, 21c, 22a, 22b, 22c, and 23a, 23b, and 23c are viewed in plan, the cutters 21a, 21b, and 21c, 22a, 22b, and 22c, and 23a, 23b, and 23c are polygonal. It is arranged surrounding the bulb 31 of the garlic 30 supported by the shelf board 4 so as to have a shape.
　これにより、切取台２２、切取台２４、切取台２６のそれぞれの形状に合せて、カッター２１ａ・２１ｂ・２１ｃ、２２ａ・２２ｂ・２２ｃ、２３ａ・２３ｂ・２３ｃを、棚板４が支持するニンニク３０の鱗茎３１を囲って配することができる。これにより、カッター２１ａ・２１ｂ・２１ｃ、２２ａ・２２ｂ・２２ｃ、２３ａ・２３ｂ・２３ｃのそれぞれを押下することで、確実に、ニンニク３０の根３２を切り取ることができる。 Thus, the garlic 30 on which the shelf board 4 supports the cutters 21a, 21b, 21c, 22a, 22b, 22c, 23a, 23b, and 23c in accordance with the shapes of the cutting table 22, the cutting table 24, and the cutting table 26. The bulb 31 can be surrounded and arranged. Thereby, the root 32 of the garlic 30 can be surely cut by pressing each of the cutters 21a, 21b, 21c, 22a, 22b, 22c, 23a, 23b, and 23c.
　しかし、例えば図６の（ａ）に示す切取台２２のように多角錐台とすると、カッター２１の分割数や、ニンニク３０の根３２を切り取る位置を変更する場合、切取台２２の形状もそれに合せて変更する必要がある。 However, for example, when a polygonal frustum is used like the cutting table 22 shown in FIG. 6A, when changing the number of divisions of the cutter 21 or the position at which the root 32 of the garlic 30 is cut, the shape of the cutting table 22 is also changed. Must be changed accordingly.
　一方、切取台１５の形状を円錐台又は円錐とすることで、ニンニク３０の根３２を切り取る量や位置を変更する場合、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのそれぞれの大きさ、すなわち、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのそれぞれに配された刃１２の大きさや、個数を変更すればよく、切取台１５の形状を変更する必要が無い。 On the other hand, when the amount or position of the root 32 of the garlic 30 is changed by changing the shape of the cutting table 15 to a truncated cone or cone, the sizes of the cutters 11a, 11b, 11c, and 11d, that is, the cutter 11a. It is only necessary to change the size and number of the blades 12 arranged on each of 11b, 11c, and 11d, and it is not necessary to change the shape of the cutting table 15.
　図７の（ａ）（ｂ）は、円形に配された複数のカッターを備える水耕栽培装置を表す平面図であり、（ａ）は２分割されたカッターを備える水耕栽培装置を表し、（ｂ）は３分割された水耕栽培装置を表す図である。 (A) (b) of Drawing 7 is a top view showing a hydroponic cultivation device provided with a plurality of cutters arranged circularly, (a) expresses a hydroponic cultivation device provided with a cutter divided into two, (B) is a figure showing the hydroponic cultivation apparatus divided into three.
　図７の（ａ）では、カッター２７は、２分割されたカッター２７ａ・２７ｂからなり、平面視したとき、円形状となるように、棚板４に挿設されている。このように、切取台１５は、カッター２７を、下限まで押下したとき、カッター２７に配された刃１２と当接するように側面が構成されている。 7 (a), the cutter 27 is composed of two divided cutters 27a and 27b, and is inserted into the shelf plate 4 so as to be circular when viewed in plan. In this way, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 27 when the cutter 27 is pressed down to the lower limit.
　図７の（ｂ）では、カッター２８は、３分割されたカッター２８ａ・２８ｂ・２８ｃからなり、平面視したとき、円形状となるように、棚板４に挿設されている。このように、切取台１５は、カッター２７を、下限まで押下したとき、カッター２７に配された刃１２と当接するように側面が構成されている。 7 (b), the cutter 28 is composed of three divided cutters 28a, 28b, and 28c, and is inserted into the shelf board 4 so as to be circular when viewed in plan. In this way, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 27 when the cutter 27 is pressed down to the lower limit.
　このように、切取台１５のように、円錐台又は円錐形とすることで、切取台１５の形状を変更することなく、カッター２７・２８のように、分割数や大きさを変更することで、ニンニク３０の根３２を切り取る量や位置を変更することができる。 Thus, by making it a truncated cone or a conical shape like the cutting table 15, it is possible to change the number of divisions and the size like the cutters 27 and 28 without changing the shape of the cutting table 15. The amount and position of the root 32 of the garlic 30 can be changed.
　このため、切取台１５のように、円錐台、又は円錐形状とすることで、コスト増加を抑え、ニンニク３０の生育に及ぼす影響の抑制と、ニンニク３０の根３２の収穫量とのバランスを、容易に取ることができる。 For this reason, like the cutting table 15, by making it a truncated cone or a cone shape, the cost increase is suppressed, and the balance between the effect on the growth of the garlic 30 and the yield of the roots 32 of the garlic 30 is balanced, Can be taken easily.
　また、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、図１の（ａ）（ｂ）で示したように棚板４が支持するニンニク３０の鱗茎３１の周囲を１周分囲む必要はなく、ニンニク３０の鱗茎３１の一部を囲って配されていればよい。また、カッター１１ａ・１１ｂ・１１ｃ・１１ｄは、常時、開口部１７ａ・１７ｂ・１７ｃ・１７ｄのそれぞれに挿入されている必要はない。 The cutters 11a, 11b, 11c, and 11d do not have to surround the circumference of the bulb 31 of the garlic 30 supported by the shelf board 4 as shown in FIGS. It suffices if it is arranged so as to surround a part of the bulb 31. Further, the cutters 11a, 11b, 11c, and 11d need not always be inserted into the openings 17a, 17b, 17c, and 17d, respectively.
　すなわち、図８に示すように、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのうち、ニンニク３０の根３２を切り取る際に、例えば、カッター１１ａなど、必要なカッターを、対応する開口部１７ａに挿設するようにしてもよい。 That is, as shown in FIG. 8, when the root 32 of the garlic 30 is cut out of the cutters 11a, 11b, 11c, and 11d, for example, a necessary cutter such as the cutter 11a is inserted into the corresponding opening 17a. You may do it.
　図８は、複数設けられた開口部の何れかにカッターを挿入する様子を表す図である。 FIG. 8 is a diagram illustrating a state in which a cutter is inserted into any of a plurality of openings.
　このように、水耕栽培装置１の棚板４には、棚板４が支持するニンニク３０の鱗茎３１の周囲を囲って配する複数のカッター１１ａ・１１ｂ・１１ｃ・１１ｄを挿設するための複数の開口部１７ａ・１７ｂ・１７ｃ・１７ｄが設けられており、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのうち少なくとも何れかが（例えばカッター１１ａ）、開口部１７ａ・１７ｂ・１７ｃ・１７ｄのうちの何れか（例えば開口部１７ａ）に挿設されていればよい。 As described above, a plurality of cutters 11 a, 11 b, 11 c, and 11 d that surround and surround the bulb 31 of the garlic 30 supported by the shelf board 4 are inserted into the shelf board 4 of the hydroponic cultivation apparatus 1. A plurality of openings 17a, 17b, 17c, and 17d are provided, and at least one of the cutters 11a, 11b, 11c, and 11d (for example, the cutter 11a) is any of the openings 17a, 17b, 17c, and 17d. (For example, the opening 17a) may be inserted.
　これにより、棚板４が支持するニンニク３０の鱗茎３１の一部を囲って、カッター１１ａを配することができる。 Thus, the cutter 11a can be disposed so as to surround a part of the bulb 31 of the garlic 30 supported by the shelf board 4.
　このように、ニンニク３０の鱗茎３１の一部だけを囲むカッター１１ａが押下されることで、カッター１１ａに配された刃１２により、ニンニク３０の根３２の一部だけを切り取ることができ、その他の部分を残すことができる。 Thus, by pressing the cutter 11a surrounding only a part of the bulb 31 of the garlic 30, only a part of the root 32 of the garlic 30 can be cut by the blade 12 arranged on the cutter 11a. Can leave a part of.
　このため、ニンニク３０の生育に及ぼす影響を抑制して、ニンニク３０の根３２を収穫することができる。また、上記植物の生育に及ぼす影響の抑制と、上記植物の根の収穫量とのバランスを、容易に取ることができる。 For this reason, the influence on the growth of garlic 30 can be suppressed, and the root 32 of garlic 30 can be harvested. In addition, it is possible to easily balance the suppression of the influence on the growth of the plant and the harvest amount of the root of the plant.
　また、開口部１７ａ・１７ｂ・１７ｃ・１７ｄのように、円形状を４等分など等分割された開口部を棚板４に設けた場合、それに挿設されるカッター１１ａ・１１ｂ・１１ｃ・１１ｄは、４つ用意する必要はなく、カッター１１ａだけ等、等分割されたうちの１つだけ用意すればよい。これにより、カッター１１を製造するコストを低下させることができる。 Further, when the shelf 4 is provided with an opening that is divided into four equal parts, such as the openings 17a, 17b, 17c, and 17d, the cutters 11a, 11b, 11c, and 11d that are inserted into the shelf 4 are provided. It is not necessary to prepare four, and only one of the equally divided parts such as the cutter 11a may be prepared. Thereby, the cost which manufactures the cutter 11 can be reduced.
　（まとめ）
　このように、植物の根を切るためのものであり、植物の栽培を行なう植物栽培装置に取り付け可能な根切り機構１０は、水耕栽培装置１に取り付けられている。そして、根切り機構１０は、ニンニク３０を支持する棚板４に、押下されることが可能に配されたカッター１１ａ・１１ｂ・１１ｃ・１１ｄと、カッター１１ａ・１１ｂ・１１ｃ・１１ｄのそれぞれの先端に配され、カッター１１ａ・１１ｂ・１１ｃ・１１ｄが押下されることで、一部を残してニンニク３０の根３２を切り取る刃１２とを備えている。 (Summary)
Thus, the root cutting mechanism 10 for cutting the roots of a plant and attachable to a plant cultivation apparatus for cultivating plants is attached to the hydroponic cultivation apparatus 1. Then, the root cutting mechanism 10 includes the cutters 11a, 11b, 11c, and 11d and the tips of the cutters 11a, 11b, 11c, and 11d, which are arranged to be pressed on the shelf plate 4 that supports the garlic 30. And a blade 12 that cuts off the root 32 of the garlic 30 leaving a part when the cutters 11a, 11b, 11c, and 11d are pressed.
　このように、先端に刃１７が配されたカッター１１ａ・１１ｂ・１１ｃ・１１ｄは、押下されることが可能に棚板４に配されている。これにより、カッター１１ａ・１１ｂ・１１ｃ・１１ｄを押下することで、棚板４が支持するニンニク３０の根３２を切り取ることができる。 Thus, the cutters 11a, 11b, 11c, and 11d having the blades 17 disposed at the tips are arranged on the shelf plate 4 so that they can be pressed. Thereby, the root | root 32 of the garlic 30 which the shelf board 4 supports can be cut off by pressing down cutter 11a * 11b * 11c * 11d.
　このため、棚板４が支持するニンニク３０の根３２を切り取るために、ニンニク３０を棚板４から取り出す必要は無く、棚板４にニンニク３０を載置したままニンニク３０の根３２を切り取ることができるので、効率よく、ニンニク３０の根３２を収穫することができる。 For this reason, in order to cut out the root 32 of the garlic 30 supported by the shelf board 4, it is not necessary to take out the garlic 30 from the shelf board 4, and the root 32 of the garlic 30 is cut out with the garlic 30 placed on the shelf board 4. Therefore, the roots 32 of garlic 30 can be efficiently harvested.
　また、栽培しているニンニク３０の根３２を一度に全て切り取ると、新しい根３２が生えるまでニンニク３０は、水や養分を吸収できなくなり、ニンニク３０が弱ったり枯れたりしてしまう場合がある。 In addition, if all the roots 32 of the garlic 30 being cultivated are cut at a time, the garlic 30 may not absorb water and nutrients until new roots 32 grow, and the garlic 30 may be weakened or withered.
　一方、上記構成によると、刃１７は、カッター１１ａ・１１ｂ・１１ｃ・１１ｄの何れかが押下されることで、ニンニク３０の根３２の一部を残して、ニンニク３０の根３２を切り取る。このように、ニンニク３０の根３２を全て切り取らず、一部を残して、ニンニク３０の根３２を切り取ることで、ニンニク３０の生育に及ぼす影響を抑制して、ニンニク３０の根３２を収穫することができる。 On the other hand, according to the above configuration, the blade 17 cuts out the root 32 of the garlic 30 while leaving any part of the root 32 of the garlic 30 by pressing one of the cutters 11a, 11b, 11c, and 11d. Thus, the root 32 of the garlic 30 is harvested by suppressing the influence on the growth of the garlic 30 by cutting out the root 32 of the garlic 30 without cutting all the roots 32 of the garlic 30 and leaving a part. be able to.
　このように、水耕栽培装置１は、根切り機構１０を備えているので、水耕栽培装置１で栽培されているニンニク３０の生育に及ぼす影響を抑制し、かつ、効率よくニンニク３０の根３２を収穫することができる。 Thus, since the hydroponics apparatus 1 is equipped with the root cutting mechanism 10, it suppresses the influence which it has on the growth of the garlic 30 cultivated by the hydroponics apparatus 1, and the root of the garlic 30 efficiently. 32 can be harvested.
　また、本実施の形態では、水耕栽培装置１が栽培する植物は、ニンニク３０であるものとして説明した。しかし、根きり機構１０を取り付ける水耕栽培装置１が栽培する植物は、根を収穫することが必要な植物であればよく、例えば、ニンニク以外にも、漢方薬や生薬として根の部分を利用する植物などをあげることができる。 Moreover, in this Embodiment, the plant which the hydroponic cultivation apparatus 1 grows demonstrated as what is the garlic 30. FIG. However, the plant cultivated by the hydroponic device 1 to which the root cutting mechanism 10 is attached may be a plant that needs to harvest roots. For example, in addition to garlic, the root portion is used as a herbal medicine or a herbal medicine. Plants can be listed.
　さらに、本実施の形態の根切り機構１０は、植物を栽培する装置に取り付けられればよく、例えば水耕栽培装置１以外にも、根にミスト状の培養液をスプレーして栽培する噴霧耕等の装置に取り付けてもよい。 Furthermore, the root cutting mechanism 10 of this Embodiment should just be attached to the apparatus which grows a plant, for example, spray culture etc. which spray and grow a mist-like culture solution on a root other than the hydroponic cultivation apparatus 1 etc. You may attach to the apparatus of.
　〔実施の形態２〕
　本発明の根切り機構の第２の実施の形態について説明する。なお、説明の便宜上、実施の形態１にて説明した図面と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 2]
A second embodiment of the root cutting mechanism of the present invention will be described. For convenience of explanation, members having the same functions as those in the drawings described in Embodiment 1 are given the same reference numerals, and descriptions thereof are omitted.
　図９は、第２の実施の形態に係る根切り機構を備えた水耕栽培装置の構成を表す断面図である。 FIG. 9 is a cross-sectional view showing a configuration of a hydroponic cultivation apparatus provided with a root cutting mechanism according to the second embodiment.
　図９に示すように、水耕栽培装置１は、根切り機構４１を備えている。根切り機構４１は、切取台１５に替えて、切取台４５を備え、さらに、気泡発生管（エアーストーン）４６を備えている点で、根切り機構１０と相違する。 As shown in FIG. 9, the hydroponic cultivation apparatus 1 includes a root cutting mechanism 41. The root cutting mechanism 41 is different from the root cutting mechanism 10 in that it includes a cutting table 45 in place of the cutting table 15 and further includes a bubble generating tube (air stone) 46.
　根切り機構４１は、カッター１１と、刃１２と、ストッパー１３と、バネ１４と、切取台４５と、気泡発生管４６とを備えている。 The root cutting mechanism 41 includes a cutter 11, a blade 12, a stopper 13, a spring 14, a cutoff table 45, and a bubble generating tube 46.
　気泡発生管４６は、培養液３に、酸素（気体）を供給するためのエアーストーンであり、酸素を多数の気泡として出力する。気泡発生管４６は、切取台４５の外部に設けられた送気ポンプ（不図示）と、中空チューブ４８で繋がれている。 The bubble generating tube 46 is an air stone for supplying oxygen (gas) to the culture solution 3, and outputs oxygen as a large number of bubbles. The bubble generating tube 46 is connected to an air supply pump (not shown) provided outside the cutoff table 45 by a hollow tube 48.
　なお、気泡発生管４６は、培養液３に酸素を出力することができればよく、空気等の酸素が含まれた気体を気泡として出力してもよい。 Note that the bubble generation tube 46 may output oxygen to the culture solution 3 and may output a gas containing oxygen such as air as bubbles.
　切取台４５は、切取台１５と同様に、ニンニク３０の下方に位置するように、培養液タンク２内に設置されている。切取台４５は、内部に、気泡発生管４６が配されている。そして、切取台４５の側面（表面）には、気泡発生管４６から出力される酸素を通す複数の開口部４７が設けられている。なお、切取台４５の形状や材質等は切取台１５と同様である。 The cutting table 45 is installed in the culture solution tank 2 so as to be located below the garlic 30, similarly to the cutting table 15. The cutout table 45 has a bubble generating tube 46 disposed therein. A plurality of openings 47 through which oxygen output from the bubble generating tube 46 passes are provided on the side surface (surface) of the cutoff table 45. The shape, material, etc. of the cutting table 45 are the same as those of the cutting table 15.
　ここで、水耕栽培では、培養液中の酸素濃度を高くすると、栽培している植物の根が良く成長することが知られている。 Here, in hydroponics, it is known that when the oxygen concentration in the culture solution is increased, the roots of the plant being grown grow well.
　そこで、根切り機構４１のように、切取台４５の内側に気泡発生管４６を設置した場合でも、切取台４５に酸素が通過できる複数の開口部４７を形成することで、ニンニク３０の根３２の部分に効果的に酸素を行き渡らせることが可能となる。根切り機構４１によると、切取台４５を配した水耕栽培装置１で栽培されているニンニク３０の根３２に、効果的に酸素を供給することができる。 Therefore, even when the bubble generating tube 46 is installed inside the cutting table 45 as in the root cutting mechanism 41, the roots 32 of the garlic 30 are formed by forming a plurality of openings 47 through which oxygen can pass through the cutting table 45. It is possible to effectively distribute oxygen to the part. According to the root cutting mechanism 41, oxygen can be effectively supplied to the roots 32 of the garlic 30 cultivated by the hydroponic cultivation apparatus 1 provided with the cutting table 45.
　また、切取台４５は、上述したように、円錐や円錐台等の錐形状である。このため、切取台４５の内部の空間が大きい下面近傍に気泡発生管４６を配置することで、多くの気泡を発生させるために、比較的、設置面積の大きな気泡発生管４６を、切取台４５の内部に設置することができる。加えて、切取台４５の側面は傾斜しているので、柱状形状など側面が垂直である場合と比べて、広範囲に、効率よく、気泡発生管４６から出力される酸素の気泡を、培養液中に分散させることができる。このように、切取台４５は、錐形状なので、効率よく、培養液３中に、酸素を供給することができる。 Further, as described above, the cutting table 45 has a cone shape such as a cone or a truncated cone. For this reason, in order to generate many bubbles by disposing the bubble generating tube 46 in the vicinity of the lower surface where the space inside the cutoff table 45 is large, the bubble generating tube 46 having a relatively large installation area is removed. Can be installed inside. In addition, since the side surface of the cutoff table 45 is inclined, oxygen bubbles output from the bubble generating tube 46 can be efficiently discharged in the culture solution over a wide range compared to the case where the side surface is vertical, such as a columnar shape. Can be dispersed. Thus, since the cutting stand 45 has a cone shape, oxygen can be efficiently supplied into the culture solution 3.
　〔実施の形態３〕
　本発明の根切り機構の第３の実施の形態について説明する。なお、説明の便宜上、実施の形態１、２にて説明した図面と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 3]
A third embodiment of the root cutting mechanism of the present invention will be described. For convenience of explanation, members having the same functions as those in the drawings described in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.
　図１０は、第３の実施の形態に係る根切り機構を備えた水耕栽培装置の構成を表す断面図である。 FIG. 10 is a cross-sectional view illustrating a configuration of a hydroponic cultivation apparatus including a root cutting mechanism according to the third embodiment.
　図１０に示すように、水耕栽培装置１は、根切り機構５１を備えている。根切り機構５１は、カッター１１に替えてカッター５２を備え、また、切取台１５に替えて切取台５５を備えている点で、根切り機構１０と相違する。 As shown in FIG. 10, the hydroponic cultivation apparatus 1 includes a root cutting mechanism 51. The root cutting mechanism 51 is different from the root cutting mechanism 10 in that a cutter 52 is provided instead of the cutter 11 and a cutting stand 55 is provided instead of the cutting stand 15.
　根切り機構４１は、カッター５２と、刃１２と、ストッパー１３と、バネ１４と、切取台５５とを備えている。 The root cutting mechanism 41 includes a cutter 52, a blade 12, a stopper 13, a spring 14, and a cutting table 55.
　カッター５２は、ストッパー１３によって棚板４に接続されている箇所、すなわち、カッター５２のうち、ストッパー１３が配されている箇所と、刃１２が配されている箇所である先端部との間に、折れ曲った屈曲部５３を有している。 The cutter 52 is connected to the shelf 4 by the stopper 13, that is, between the portion where the stopper 13 is disposed in the cutter 52 and the tip portion where the blade 12 is disposed. The bent portion 53 is bent.
　屈曲部５３では、カッター５２は、カギ型に折れ曲がっている。すなわち、カッター５２のうち、ストッパー１３で固定されている箇所から先端部に向かう方向に含まれる屈曲部５３では、棚板４に並行であり切取台５５に向かう方向に折れ曲り、さらに、鉛直方向下向きの方向に折れ曲っている。 At the bent portion 53, the cutter 52 is bent into a key shape. That is, in the cutter 52, the bent portion 53 included in the direction from the portion fixed by the stopper 13 toward the tip portion is bent in the direction parallel to the shelf board 4 and toward the cut-out table 55, and further in the vertical direction. It is bent in the downward direction.
　また、屈曲部５３は、上記の方向のように折れ曲る形状に限定されず、例えば、カッター５２のうち、ストッパー１３で固定されている箇所から、棚板４に並行であり切取台５５から離れる方向に折れ曲り、さらに、鉛直方向下向きの方向に折れ曲っている形状であってもよい。 Moreover, the bending part 53 is not limited to the shape bent like said direction, For example, from the location currently fixed with the stopper 13 among the cutters 52, it is parallel to the shelf 4 and from the cutting stand 55 It may be a shape that is bent in a direction away from it and further bent in a downward direction in the vertical direction.
　ニンニク３０の根３２を切断するとき、カッター１１で切断するときより、内側で切断する必要がある場合や、外側で切断する必要がある場合がある。 When cutting the root 32 of the garlic 30, it may be necessary to cut on the inner side or on the outer side than when cutting with the cutter 11.
　そこで、カッター５２のように、屈曲部５３を設け、屈曲部５３の形状を調整することで、カッター５２が押下された際の、カッター５２に配された刃１７と、刃１７が当接する切取台５５の側面（表面）との相対位置を変更することができる。このため、ニンニク３０の根３２を切り取る位置を調整することができる。このため、根切り機構５１は、根切り機構１０と比べて、利便性を向上させることができる。 Therefore, like the cutter 52, the bending portion 53 is provided, and the shape of the bending portion 53 is adjusted so that the blade 17 disposed on the cutter 52 and the blade 17 abut when the cutter 52 is pressed down. The relative position with the side surface (surface) of the base 55 can be changed. For this reason, the position which cuts off the root 32 of the garlic 30 can be adjusted. For this reason, the root cutting mechanism 51 can improve convenience compared to the root cutting mechanism 10.
　切取台５５は、円錐形状であって、頂点が培養液３の水面から突出し、ニンニク３０の発根部分近傍に位置するような高さで形成されている。 The cutting stand 55 has a conical shape, and has a height such that the apex protrudes from the water surface of the culture solution 3 and is located near the root portion of the garlic 30.
　このように、切取台５５は、頂点が、棚板４の開口部７の内部に含まれる程度の高さを有している。このため、切取台５５の頂点を、ニンニク３０の発根部分との距離を近づけることができる。これにより、ニンニク３０の根３２がまんべんなく広がるようにコントロールすることができる。 Thus, the cutting table 55 has such a height that the apex is included in the opening 7 of the shelf board 4. For this reason, the distance between the apex of the cutting table 55 and the root portion of the garlic 30 can be reduced. Thereby, it can control so that the root 32 of the garlic 30 may spread evenly.
　図１１の（ａ）は鱗片３３から発根している様子を表す斜視図であり、（ｂ）は鱗片の発根部分を表す平面図である。 (A) of FIG. 11 is a perspective view showing a state of rooting from the scale 33, and (b) is a plan view showing a rooting portion of the scale.
　ニンニク３０として、１つの鱗片（植物）３３を棚板４に載置することで、鱗片３３から根３２を発根させることもできる。根３２は、図１１の（ａ）（ｂ）に示すように、鱗片３３の下部から周状に発根する。このため、切取台５５を、円錐台として構成する場合、鱗片３３に近い側の上底の面積は、鱗片３３の下部の発根部分で囲まれている周状の面積より小さいことが好ましい。 As the garlic 30, the root 32 can be rooted from the scale 33 by placing one scale (plant) 33 on the shelf 4. As shown in FIGS. 11A and 11B, the root 32 roots in a circumferential shape from the lower part of the scale 33. For this reason, when the cutting stand 55 is configured as a truncated cone, the area of the upper base near the scale 33 is preferably smaller than the circumferential area surrounded by the root portion at the bottom of the scale 33.
　これにより、鱗片３３の根３２が、切取台５５の側面で、まんべんなく広がるようにコントロールすることができる。 Thereby, the root 32 of the scale 33 can be controlled to spread evenly on the side surface of the cutting stand 55.
　また、切取台５５の頂点を、ニンニク３０の発根部分との距離を近づけることで、根３２をより根元で切ることが可能となる。 Also, the root 32 can be cut at the root by making the apex of the cutting stand 55 closer to the root of the garlic 30.
　図１２は、根３２を空気中で切り取る水耕栽培装置の様子を表す図である。 FIG. 12 is a diagram illustrating a state of a hydroponic cultivation apparatus that cuts the root 32 in the air.
　図１２に示すように、根３２を培養液３中ではなく、空気中で切る必要がある場合がある。このような場合、特に、培養液３の水面より上の部分に切取台５５が突出している必要がある。 As shown in FIG. 12, it may be necessary to cut the root 32 in the air instead of in the culture solution 3. In such a case, in particular, the cutting table 55 needs to protrude above the water surface of the culture solution 3.
　切り取った根３２の根先（切り取り面）が培養液３中に浸かっていると、培養液３中のバクテリアの影響で根３２が変色したり、培養液３の水質を悪化させたりする可能性がある。このような場合に、空気中で根３２を切ることでこれを防ぐことが可能となる。 If the root (cut surface) of the cut root 32 is immersed in the culture solution 3, the root 32 may be discolored due to the bacteria in the culture solution 3, or the water quality of the culture solution 3 may be deteriorated. There is. In such a case, this can be prevented by cutting the root 32 in the air.
　また、切取台５５の側面の傾斜角度を調整することによっても、カッター５２を押下することで切断されるニンニク３０の根３２の位置を調整することができる。 Also, the position of the root 32 of the garlic 30 to be cut can be adjusted by pressing the cutter 52 by adjusting the inclination angle of the side surface of the cutoff table 55.
　〔実施の形態４〕
　本発明の根切り機構の第４の実施の形態について説明する。なお、説明の便宜上、実施の形態１～３にて説明した図面と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。 [Embodiment 4]
A fourth embodiment of the root cutting mechanism of the present invention will be described. For convenience of explanation, members having the same functions as those in the drawings described in the first to third embodiments are denoted by the same reference numerals and description thereof is omitted.
　図１３は、第４の実施の形態に係る根切り機構を備えた水耕栽培装置の構成を表す断面図である。 FIG. 13 is a cross-sectional view illustrating a configuration of a hydroponic cultivation apparatus including a root cutting mechanism according to the fourth embodiment.
　図１３に示すように、水耕栽培装置（植物栽培装置）６０は、複数の根切り機構１０ａ・１０ｂ・１０ｃを備えている。水耕栽培装置６０は、複数のニンニク３０を栽培することができるものである。 As shown in FIG. 13, the hydroponic cultivation apparatus (plant cultivation apparatus) 60 includes a plurality of root cutting mechanisms 10a, 10b, and 10c. The hydroponic cultivation apparatus 60 can grow a plurality of garlics 30.
　水耕栽培装置６０は、棚板４に替えて棚板６４を備え、また、培養液タンク２に替えて培養液タンク６２を備えている点で水耕栽培装置１と相違する。 The hydroponic cultivation device 60 is different from the hydroponic cultivation device 1 in that a shelf plate 64 is provided instead of the shelf plate 4 and a culture solution tank 62 is provided instead of the culture solution tank 2.
　培養液タンク６２は、複数の根切り機構を内部に設置可能な程度の大きさで構成されている。本実施の形態では、培養液タンク６２内には、３個の根切り機構１０ａ・１０ｂ・１０ｃが設置されている。 The culture medium tank 62 has a size that allows a plurality of root cutting mechanisms to be installed therein. In the present embodiment, three root cutting mechanisms 10 a, 10 b, and 10 c are installed in the culture medium tank 62.
　根切り機構１０ａ・１０ｂ・１０ｃは、それぞれ、カッター１１と、刃１２と、ストッパー１３と、バネ１４と、切取台４５とを備えている。根切り機構１０ａ・１０ｂ・１０ｃのそれぞれは、水耕栽培装置６０で栽培される複数のニンニク３０のそれぞれに対応して水耕栽培装置６０に設けられる。 Each of the root cutting mechanisms 10a, 10b, and 10c includes a cutter 11, a blade 12, a stopper 13, a spring 14, and a cutoff table 45. Each of the root cutting mechanisms 10 a, 10 b, and 10 c is provided in the hydroponic cultivation device 60 corresponding to each of the plurality of garlics 30 cultivated by the hydroponic cultivation device 60.
　棚板６４は、水耕栽培装置６０で複数のニンニク３０を栽培するために、複数のニンニク３０の鱗茎３１を載置することができる程度の大きさで構成されている。 The shelf board 64 is configured to have such a size that the bulbs 31 of the plurality of garlics 30 can be placed in order to cultivate the plurality of garlics 30 by the hydroponic cultivation device 60.
　棚板６４は、載置された複数のニンニク３０の鱗茎３１の発根部分のそれぞれに対応して、複数の開口部７が形成されている。さらに、棚板６４には、載置される複数のニンニク３０の鱗茎３１のそれぞれの周囲を囲って、根切り機構１０ａ・１０ｂ・１０ｃのそれぞれのカッター１１を挿設するための複数の開口部１７が設けられている。そして、根切り機構１０ａ・１０ｂ・１０ｃのそれぞれのカッター１１は、棚板６４に形成された複数の開口部１７のそれぞれに挿設されている。 The shelf plate 64 has a plurality of openings 7 corresponding to the rooted portions of the bulbs 31 of the plurality of garlics 30 placed thereon. Furthermore, a plurality of openings for inserting the cutters 11 of the root cutting mechanisms 10 a, 10 b, and 10 c so as to surround the bulbs 31 of the plurality of garlics 30 placed on the shelf plate 64. 17 is provided. The cutters 11 of the root cutting mechanisms 10a, 10b, and 10c are inserted into the plurality of openings 17 formed in the shelf plate 64, respectively.
　このように、水耕栽培装置６０は、複数の根切り機構１０ａ・１０ｂ・１０ｃを備え、根切り機構１０ａ・１０ｂ・１０ｃのそれぞれのカッター１１が配されている棚板６４が共通して構成されている。 As described above, the hydroponic cultivation apparatus 60 includes a plurality of root cutting mechanisms 10a, 10b, and 10c, and a common shelf board 64 on which the cutters 11 of the root cutting mechanisms 10a, 10b, and 10c are arranged. Has been.
　これにより、水耕栽培装置６０で、複数のニンニク３０が栽培されていたとしても、当該複数のニンニク３０のそれぞれを、棚板６４から取り外すことなく、それぞれのニンニク３０の根３２を収穫することができる。これにより、効率よく、水耕栽培装置６０でニンニク３０を栽培することができると共に、ニンニク３０の生育に及ぼす影響を抑制し、かつ、効率よくそれぞれのニンニク３０の根３２を収穫することができる。 Thereby, even if a plurality of garlics 30 are cultivated in the hydroponic cultivation device 60, the roots 32 of each garlic 30 are harvested without removing each of the plurality of garlics 30 from the shelf board 64. Can do. Thereby, while being able to cultivate the garlic 30 efficiently with the hydroponic cultivation apparatus 60, the influence which it has on the growth of the garlic 30 can be suppressed, and the root 32 of each garlic 30 can be efficiently harvested. .
　このように、水耕栽培装置６０では、培養液タンク６２は１個のままで複数のニンニク３０を栽培することができるので、コストを抑えて効率的に植物の栽培が可能である。 Thus, in the hydroponic cultivation apparatus 60, since the plurality of garlics 30 can be cultivated with the single culture medium tank 62, plants can be cultivated efficiently at a reduced cost.
　また、根切り機構１０ａ・１０ｂ・１０ｃそれぞれの切取台４５は、接続部６５によって、下面近傍で、互いに接続されている。そして、複数の切取台４５及び接続部６５の内部には、気泡発生管４６よりも大きい気泡発生管（エアーストーン）６６が配されている。気泡発生管６６は、複数の切取台４５に跨って配されている。そして、気泡発生管６６は、切取台４５の外部に設けられた送気ポンプ（不図示）と、中空チューブ６８で繋がれている。 Further, the respective cutting bases 45 of the root cutting mechanisms 10a, 10b, and 10c are connected to each other in the vicinity of the lower surface by the connecting portion 65. Inside the plurality of cutoff tables 45 and connection portions 65, a bubble generating tube (air stone) 66 larger than the bubble generating tube 46 is arranged. The bubble generating tube 66 is arranged across the plurality of cutoff tables 45. The bubble generating tube 66 is connected to an air supply pump (not shown) provided outside the cutoff table 45 by a hollow tube 68.
　接続部６５にも、酸素が通過できる複数の開口部４７が形成されている。これにより、気泡発生管６６から出力される酸素を、複数のニンニク３０の根３２の部分に効果的に行き渡らせることが可能となる。 The connection portion 65 is also formed with a plurality of openings 47 through which oxygen can pass. Thereby, the oxygen output from the bubble generating tube 66 can be effectively spread to the root 32 portions of the plurality of garlics 30.
　なお、接続部６５は必ずしも設ける必要はなく、根切り機構１０ａ・１０ｂ・１０ｃそれぞれの切取台４５は互いに分離された構成であってもよい。この場合、気泡発生管６６に替えて、根切り機構１０ａ・１０ｂ・１０ｃそれぞれの切取台４５内部に納まるように、上述した気泡発生管４６を設けることが好ましい。 In addition, the connection part 65 does not necessarily need to be provided, and the cutting tables 45 of the root cutting mechanisms 10a, 10b, and 10c may be separated from each other. In this case, it is preferable to provide the above-described bubble generation tube 46 so that the bubble generation tube 66 is accommodated in the cut-out table 45 of each of the root cutting mechanisms 10a, 10b, and 10c.

The root cutting mechanism 71 includes a cutting base 75 instead of the cutting base 15, and the arrangement of the cutter 72 is different from the root cutting mechanism 10.
　根切り機構７１は、カッター（可動部）７２と、刃１２と、ストッパー１３（図１４の（ａ）（ｂ）には不図示）と、バネ１４（図１４の（ａ）（ｂ）には不図示）と、切取台７５と、を備えている。カッター７２は、横並びに配された複数のカッター７２ａ・７２ｂ・７２ｃ・７２ｄからなるカッター群（第１の可動部群）７２Ａと、横並びに配された複数のカッター７２ｅ・７２ｆ・７２ｇ・７２ｈからなるカッター群（第２の可動部群）７２Ｂとからなる。 The root cutting mechanism 71 includes a cutter (movable part) 72, a blade 12, a stopper 13 (not shown in FIGS. 14A and 14B), and a spring 14 (FIGS. 14A and 14B). (Not shown) and a cutting stand 75. The cutter 72 includes a cutter group (first movable part group) 72A composed of a plurality of cutters 72a, 72b, 72c, and 72d arranged side by side, and a plurality of cutters 72e, 72f, 72g, and 72h arranged side by side. And a cutter group (second movable part group) 72B.
　図１４の（ａ）に示すように、切取台７５は、カッター（可動部）７２を、下限まで押下したとき、カッター７２に配された刃１２と当接する側面（表面）を含むものである。 14A, the cutting table 75 includes a side surface (surface) that comes into contact with the blade 12 disposed on the cutter 72 when the cutter (movable part) 72 is pressed down to the lower limit.
　切取台７５は、上方から下方にかけて、上記側面間の距離が、次第に広がっている。これにより、カッター７２を押下したとき、カッター７２に配された刃１２を、切取台７５の表面に当接させることができる。従って、カッター７２を押下することで、ニンニク３０の根３２を収穫することができる。 The distance between the side surfaces of the cutoff table 75 gradually increases from the top to the bottom. Thereby, when the cutter 72 is pressed, the blade 12 disposed on the cutter 72 can be brought into contact with the surface of the cutting table 75. Therefore, by pressing the cutter 72, the roots 32 of the garlic 30 can be harvested.
　切取台７５の形状は、筋状に盛り上がった畝形状である。切取台７５は、培養液タンク２の長手方向に延びて、筋状に形成されている。また、切取台７５は、筋状に延びる方向である長手方向に直交する方向である短手方向の断面が台形である。台形の斜面が、上記側面である。 The shape of the cutting stand 75 is a ridge shape raised in a streak shape. The cutting stand 75 extends in the longitudinal direction of the culture medium tank 2 and is formed in a streak shape. Further, the cutting table 75 has a trapezoidal cross section in the short direction, which is a direction perpendicular to the longitudinal direction, which is a direction extending in a streak shape. The trapezoidal slope is the side surface.
　このように、切取台７５は、形状の一例として畝形状として構成されている。これにより、棚板４に載置されたニンニク３０の根３２が、刃１２と、切取台７５の側面との間に配されることになる。ニンニク３０の根３２は、切取台７５の側面に沿って伸びることになる。 Thus, the cutting stand 75 is configured as a bowl shape as an example of the shape. As a result, the roots 32 of the garlic 30 placed on the shelf board 4 are arranged between the blade 12 and the side surface of the cutout table 75. The root 32 of the garlic 30 will extend along the side surface of the cutout 75.
　このため、複数のカッター７２ａ～７２ｆのうち、押下されたカッター７２ａ～７２ｆによって、ニンニク３０の根３２は、切取台７５の側面に押圧されて切断される。これにより、ニンニクの根３２を確実に切り取ることができるので、効率よく、ニンニク３０の根３２を収穫することができる。 For this reason, the root 32 of the garlic 30 is pressed against the side surface of the cutting table 75 and cut by the pressed cutters 72a to 72f among the plurality of cutters 72a to 72f. As a result, the garlic roots 32 can be reliably cut out, and the garlic 30 roots 32 can be efficiently harvested.
　棚板４には、カッター７２ａ～７２ｈのそれぞれを挿設するための複数の開口部７７が設けられている。そして、カッター７２ａ～７２ｆは、棚板４に設けられた複数の開口部７７に挿設されている。カッター７２ａ・７２ｂ・７２ｃ・７２ｄのそれぞれと、カッター７２ｅ・７２ｆ・７２ｇ・７２ｈのそれぞれとは、棚板４の長手方向に横並びに配されている。 The shelf plate 4 is provided with a plurality of openings 77 for inserting the cutters 72a to 72h. The cutters 72a to 72f are inserted into a plurality of openings 77 provided in the shelf board 4. Each of the cutters 72a, 72b, 72c, and 72d and each of the cutters 72e, 72f, 72g, and 72h are arranged side by side in the longitudinal direction of the shelf board 4.
　カッター群７２Ａと、カッター群７２Ｂとは、棚板４が支持するニンニク３０を挟むことが可能な程度に離間して配されている。すなわち、カッター７２ａ・７２ｂ・７２ｃ・７２ｄのそれぞれと、カッター７２ｅ・７２ｆ・７２ｇ・７２ｈのそれぞれとは、棚板４の短手方向に、互いに対向して、棚板４に配されている。ニンニク３０は、カッター群７２Ａと、カッター群７２Ｂとの間に配されている。 The cutter group 72 </ b> A and the cutter group 72 </ b> B are arranged so as to be separated so as to sandwich the garlic 30 supported by the shelf board 4. That is, each of the cutters 72a, 72b, 72c, and 72d and each of the cutters 72e, 72f, 72g, and 72h are disposed on the shelf plate 4 so as to face each other in the short direction of the shelf plate 4. The garlic 30 is arranged between the cutter group 72A and the cutter group 72B.
　そして、カッター群７２Ａ及びカッター群７２Ｂのそれぞれを構成するカッター７２ａ～７２ｆは、それぞれ独立して、押下されることが可能である。 The cutters 72a to 72f constituting each of the cutter group 72A and the cutter group 72B can be pressed independently.
　このため、複数のカッター７２ａ～７２ｆのうち、押下されたカッター７２ａ～７２ｆの先端に配されている刃１２によってだけニンニク３０の根３２を切り取ることができるので、ニンニク３０の生育に及ぼす影響を抑制して、ニンニク３０の根３２を収穫することができる。 For this reason, since the root 32 of the garlic 30 can be cut out only by the blade 12 disposed at the tip of the pressed cutters 72a to 72f among the plurality of cutters 72a to 72f, the influence on the growth of the garlic 30 is affected. The roots 32 of garlic 30 can be harvested with inhibition.
　なお、棚板４の長手方向に配されているカッター７２の個数は、本実施の形態のように４個に限定されず、５個以上であってもよいし、３個以下であってもよい。 Note that the number of cutters 72 arranged in the longitudinal direction of the shelf board 4 is not limited to four as in the present embodiment, and may be five or more, or may be three or less. Good.
　さらに、図１５に示すように、切取台の短手方向の断面を、台形ではなく、三角形にしてもよい。 Furthermore, as shown in FIG. 15, the cross section in the short direction of the cutting table may be a triangle instead of a trapezoid.
　図１５の水耕栽培装置１は、根切り機構７６を備えている。根切り機構７６は、切取台７５に替えて切取台７８を備えている。切取台７８の形状は、筋状に盛り上がった畝形状である。すなわち、切取台７８は、培養液タンク２の長手方向に延びて、筋状に形成されている。 15 has a root cutting mechanism 76. The root cutting mechanism 76 includes a cutting table 78 instead of the cutting table 75. The shape of the cutting stand 78 is a ridge shape raised in a streak shape. That is, the cutting stand 78 extends in the longitudinal direction of the culture medium tank 2 and is formed in a streak shape.
　そして、切取台７８の形状は、上記筋状に延びる方向（すなわち延設方向）と直交する方向の断面が三角形である。切取台７８では、上記三角形の斜面が、カッター７２の刃１２と当接させるための側面である。これにより、切取台７５と同様の効果を得ることができる。 And the shape of the cutting stand 78 has a triangular cross section in a direction orthogonal to the direction extending in the above-mentioned streak shape (that is, the extending direction). In the cutting stand 78, the triangular slope is a side surface for contacting the blade 12 of the cutter 72. Thereby, the same effect as the cutoff stand 75 can be acquired.
　また、図１４の（ａ）（ｂ）、図１５に示した切取台７５・７８のように、形状を畝形状とすることで、複数の植物５の根３２を切り取る根切り機構へと装置構成の拡張が容易となる。すなわち、棚板４に複数の植物５を載置し、栽培する場合、当該複数の植物５に共通する切取台７５・７８として構成することができる。このため、棚板４に、複数の植物５を載置する場合に、複数の植物５の間隔や密植度を自由に選択することができる。 Further, as shown in FIGS. 14 (a) and 14 (b) and the cutting tables 75 and 78 shown in FIG. 15, the shape is made into a bowl shape so that a root cutting mechanism for cutting the roots 32 of a plurality of plants 5 is obtained. The configuration can be easily expanded. That is, when mounting and cultivating a plurality of plants 5 on the shelf board 4, it can be configured as the cutting tables 75 and 78 common to the plurality of plants 5. For this reason, when mounting the some plant 5 on the shelf board 4, the space | interval and dense planting degree of the some plant 5 can be selected freely.
　また、カッター７２は、カッター群７２Ａと、カッター群７２Ｂとからなる。このため、同様に、複数の植物５の根３２を切り取る根切り機構へと装置構成の拡張が容易となる。すなわち、棚板４に複数の植物５を載置し、栽培する場合、当該複数の植物５に共通して横並びに配された複数のカッター７２からなるカッター群７２Ａと、カッター群７２Ｂとを構成することができる。このため、棚板４に、複数の植物５を載置する場合に、複数の植物５の間隔や密植度を自由に選択することができる。 Further, the cutter 72 includes a cutter group 72A and a cutter group 72B. For this reason, similarly, it becomes easy to expand the device configuration to a root cutting mechanism for cutting the roots 32 of the plurality of plants 5. That is, when placing and cultivating a plurality of plants 5 on the shelf board 4, a cutter group 72 </ b> A composed of a plurality of cutters 72 arranged side by side in common with the plurality of plants 5 and a cutter group 72 </ b> B are configured. can do. For this reason, when mounting the some plant 5 on the shelf board 4, the space | interval and dense planting degree of the some plant 5 can be selected freely.
