に植え込む土壌栽培と、養分を溶解させた水溶液
のみで土壌を使用しない水耕栽培とがある。 Traditionally, when cultivating plants for ornamental purposes indoors such as at home or in offices, or for growing plants in gardens, soil cultivation in artificial soil, potting soil, peat, etc., and dissolution of nutrients have been used. There is hydroponic cultivation, which uses only an aqueous solution and no soil.

への給水量を調節することが開示されている。 Prior art of means for arranging a large number of containers for growing these plants (hereinafter referred to as planting containers) and adjusting the amount of water supplied when supplying an aqueous solution or water to each of these planting containers (hereinafter simply referred to as water supply) As, Utility Model Publication No. 58-5487 and Utility Model Application Publication No. 61-60651
In both publications, a number of water supply pipes are connected to a water supply tank located above the plant container or a water supply pump installed at a location away from the plant container, and the tip of each corresponding water supply pipe is connected to the plant container. It is disclosed that a flow rate control valve of a conventionally known structure is provided in the middle of each water supply pipe, and the amount of water supplied to each plant container is adjusted by operating each flow rate control valve.

〔考案が解決しようとする課題〕[The problem that the idea attempts to solve]

ところで、植木容器の設置高さが各々異なる場
合には、上部の給水タンクからその下方の各給水
管先端までの全水頭が異なり、同じ内径の給水管
を使用すると、低い高さ位置の植木容器に対する
給水管の単位時間あたりの流量は多い一方、高い
位置の植木容器に対する給水管の流量は少なくな
るというように各植木容器に対する給水量のばら
つきが大きい。 By the way, if the installation heights of the planting containers are different, the total water head from the upper water supply tank to the tip of each water supply pipe below will be different, and if water supply pipes with the same inner diameter are used, the planting containers at a lower height will be different. The amount of water supplied to each plant container varies widely, such that the flow rate per unit time of the water supply pipe for the plant container is large, while the flow rate of the water pipe for the plant container in a high position is small.

しかも、給水タンクでの給水量が時間的に変動
すると各給水管への分配給水量も時間的に変動す
る。 Moreover, when the amount of water supplied in the water tank changes over time, the amount of water distributed to each water supply pipe also changes over time.

しかるに、前記各先行技術における流量調節
は、各給水管での最大流量から絞つて流量を減少
させる調節であつて、時間的に一定の給水量を保
持できるものではなかつた。 However, the flow rate adjustment in each of the above-mentioned prior art is an adjustment to reduce the flow rate by restricting the maximum flow rate in each water supply pipe, and it is not possible to maintain a constant water supply amount over time.

この不都合を解消する先行技術として、特公昭

ず、略一定量に保持する構成が開示されている。 As a prior art to solve this inconvenience,
In Publication No. 60-22885, a water supply tank is provided for each water supply section to each plant container, and the water tank is provided with a metering orifice and an overflow pipe that communicate with the plant container, so that the hydrostatic pressure in each water tank is kept constant. The amount of water supplied from the metering orifice to the planting container,
A configuration is disclosed in which the amount of water supplied to the water tank is maintained at a substantially constant amount regardless of temporal fluctuations in the amount of water supplied to the water supply tank.

しかし、この構成によれば、給水量を変更する
には計量オリフイスを取り替えるかオーバーフロ
ー管の上端の高さ位置を変更するなど、調節操作
が面倒である。 However, according to this configuration, adjustment operations such as replacing the metering orifice or changing the height position of the upper end of the overflow pipe are troublesome in order to change the water supply amount.

しかも、これらの先行技術では、給水管の先端

おそれがあつた。 Moreover, in these prior art, all the water supplied from the tip of the water supply pipe or the metering orifice goes into the planting container, and there is no drainage measure in case the amount of water supplied is excessive, so the amount of water supplied is When the amount of water supplied is too high, the roots of the plants in the container may rot, and on the other hand, when the amount of water supplied is too little, there is a risk that the plants may wither.

本考案は、前記のいずれの課題をも簡単な構成
により解決しようとするものである。 The present invention attempts to solve all of the above-mentioned problems with a simple configuration.

〔課題を解決するための手段〕[Means to solve the problem]

そのため本考案では、植木容器の本体一側部

た構成としたものである。 Therefore, in the present invention, a water supply port and a drainage port are formed in one side of the main body of the plant container, separated vertically and appropriately, and a hollow arm portion is protruded sideways so as to surround the drainage port and water supply port. The bottom surface of the arm part is formed into a drain gutter that communicates with the drain port, and the arm part has a bottom surface that is inclined downward from the tip opening toward one side of the main body, and has a bottom surface below the water supply port. A water supply gutter connected to the drain gutter is provided, and the water supply gutter is provided with a bypass port that opens into the drain gutter, and a bypass port is provided at or near the bypass port, and when the flow rate from the bypass port to the drain gutter increases, the water supply gutter is connected to the water supply gutter. The valve body is provided with a valve body that reduces the flow rate of the water supply port, and the arm portion is provided with an operating body that operates the valve body from the outside to adjust the flow rate to the water supply port.

〔考案の作用及び効果〕[Functions and effects of the invention]

この構成により、植木容器の本体一側部に横向

器の本体内に給水すべき流量よりも多くし、且つ
バイパス口を略塞いだ状態においては、給水口か
ら本体内に流入しきれない水はアーム部の先端開
口部からオーバーフローする。 With this configuration, when water is supplied to the water supply gutter from the tip opening of the hollow arm projecting laterally from one side of the main body of the plant container, the water flowing on the water supply gutter heads toward the water supply port. The water supply gutter is provided with a bypass port that opens into the drain gutter, and a valve body is provided at or near the bypass port to reduce the flow rate to the water supply port when the flow rate from the bypass port to the drain gutter increases. Therefore, if the amount of water supplied to the water gutter is higher than the amount of water that should be supplied into the main body of the plant container, and the bypass port is almost blocked, water that cannot flow into the main body from the water supply port will be drained from the arm. overflows from the tip opening of the section.

反対に、給水口から植木容器本体内への流入量
を減少させるべく、弁体を操作すると、バイパス
口から排水樋への流量が増大するのであり、この
場合排水樋上の水はアーム部の先端開口部から外
に出るから、給水樋への給水量が多くても、本体
内への給水量は減少された状態を保持できる。 On the other hand, if you operate the valve body to reduce the flow from the water supply port into the plant container body, the flow from the bypass port to the drain gutter will increase, and in this case, the water on the drain gutter will flow to the tip of the arm. Since the water goes out through the opening, even if the amount of water supplied to the water supply gutter is large, the amount of water supplied into the main body can be maintained at a reduced level.

また、給水樋への給水量が少ない状態であつて
も、その略全量を給水口から本体内に流入させる
には、バイパス口への流量を減少させたまたは遮
断するように弁体を調節しておけば良く、適宜少
ない流量を給水口に送るには、弁体にてバイパス
口への流量を調節すれば良い。 In addition, even if the amount of water supplied to the water supply gutter is low, in order to allow almost all of the water to flow into the main unit from the water supply port, the valve body must be adjusted to reduce or block the flow to the bypass port. In order to send an appropriately small flow rate to the water supply port, the flow rate to the bypass port may be adjusted using the valve body.

このように、植木容器の本体内への給水量は、
給水樋への給水量の大小に拘わらず一定の量に調
節できる。 In this way, the amount of water supplied into the main body of the plant container is
Regardless of the amount of water supplied to the water gutter, it can be adjusted to a constant amount.

しかも、この弁体は操作体によりアーム部の外
側から操作できるものであり、給水口から植木容
器の本体内への給水量の増減調節が至極簡単に実
行できる効果を有するものである。 In addition, this valve body can be operated from the outside of the arm portion using an operating body, and has the effect that it is extremely easy to increase or decrease the amount of water supplied from the water supply port into the main body of the plant container.

るという顕著な効果を有するのである。 In this way, according to the present invention, it is possible to adjust the amount of water supplied to one planting container at the maximum flow rate while limiting the amount of water supplied to the other planting container. It has the remarkable effect of making it possible to arrange planting containers for different plant types and combinations of soil cultivation and hydroponic cultivation, such as planting containers for hydroponic cultivation and planting containers for plants such as cacti that require little water supply. We have it.
