Description

TECHNICAL FIELD The present invention relates to a plant cultivation device suitable for cultivating a plant for appreciation or decoration in a general home or a room of a building.

[Conventional technology]

A large number of so-called hydroponic cultivation apparatuses for culturing plants by supplying a culture solution to an appropriate cultivation bed without using soil are known. However, most of them are for large-scale cultivation of vegetables and horticultural plants for sale, and the plant cultivation surface is horizontal or inclined. When cultivating a plant for appreciation at home or in a building, it is often impossible to obtain a large installation floor area, and therefore it cannot be used simply by downsizing a commercial cultivation device.

Cultivation devices designed to grow as many plants as possible in a room with a limited installation floor area have also been proposed, but they have been proposed by arranging horizontal small-scale cultivation surfaces vertically. The cultivation area is more than the installation floor area. However, these cultivation apparatuses have a complicated mechanism for uniformly supplying a culture solution to each cultivation surface and performing illumination evenly, resulting in an expensive apparatus.

[Problems to be Solved by the Invention]

Therefore, the present invention is intended to provide a plant cultivation device capable of securing a large cultivation area with a small floor area, illuminating a cultivated plant easily, and having a simple structure.

Another object of the present invention is to provide a plant cultivating device which can be easily moved as a whole and can be made excellent as an interior.

Another object of the present invention is to provide a cultivating device capable of cultivating and displaying a plant on a completely vertical surface, which is impossible with conventional cultivating devices.

[Means for solving the problem]

The plant cultivating apparatus provided by the present invention is such that a right-angled cut end of a short pipe whose one end is obliquely cut is fitted and fixed to the plate by forming a hole in the plate and elastically applied to the fixed pipe from the right-angle cut end side. A major feature is that a cultivation plate having a foamed plant-holding plug (hereinafter simply referred to as a plug) fitted therein is used in a vertical arrangement.

That is, the cultivation plate is fixed so that the planted pipe is horizontal, but with the diagonal cutting surface of the pipe facing downward and detachably fixed to the grid-shaped support frame in the upright position, and the cultivation plate is fixed. A shallow box-shaped body is joined to the protruding surface side of the obliquely cut end of the pipe of the formed support frame to form a cultivation box. Then, a culture solution tank is installed below the cultivation box, a spray nozzle for spraying the culture solution into the cultivation box core space is installed at the top of the cultivation box, and the culture solution in the culture solution tank is pressure-fed to the spray nozzle and A culture solution circulating means is provided for causing the culture solution sprayed from the spray nozzle into the space inside the cultivation box to flow back to the culture solution tank from the bottom of the cultivation box.

Although one pipe may be planted in one cultivation plate, a plurality of pipes are usually arranged at appropriate intervals according to the type of plant. In that case, make sure that the diagonal cut ends of all pipes are aligned. The inclination angle of the diagonal cut end of the pipe is
45 ° ± 5 ° is suitable. The length of the pipe is 40-50 mm
The thickness is 18-25 depending on the type of plant to be cultivated.
Select in the range of mm. The shape and size of the cultivation plate can be arbitrarily selected.

As the plug fitted to the pipe, a plug made of a foam of a hydrophobic elastic polymer such as silicone or polyurethane is preferable because it has excellent water-stopping property, but is not limited thereto. It is desirable to make a cut in the stopper in the longitudinal direction so as to reach the central shaft stopper (as will be described later, the notch may be made at that stage because it is necessary when actually planting the plant).

It is desirable to have a watertight structure at the joints of each part of the cultivation box such as the cultivation plate attachment part and the support frame joint part so that the culture solution does not leak out, but the part where there is no risk of liquid leakage such as the top is an open structure. It doesn't matter. The cultivation box, the culture solution tank, the culture solution circulation means and the like may all be integrated to facilitate movement. Further, the interior property can be improved by, for example, finishing the parts other than the cultivation plate with a wood material to make them furniture-like.

[Action]

Cultivation of a plant by this device is basically a hydroponic culture, but a cultivation bed using gravel or the like is not used, and roots are exposed in the space inside the cultivation box. The plant to grow is
The seedlings are grown in advance in a nursery bed using any other cultivation device or soil and the roots are sufficiently elongated.

When planting seedlings, open the plug removed from the pipe at the cut that reaches the center axis (if not cut, open the cut) to hold the seedling stem. At this time, it is arranged so that most of the roots are exposed from the tip of the stopper. Next, the plug holding the seedling is inserted into the pipe while pushing the root into the cultivation box to fix the seedling to the pipe. The elastic foam stopper holds and secures the seedling securely without damaging it. When the culture solution circulation means is operated and the culture solution is sprayed by the spray device, the culture solution droplets that drop in the cultivation box adhere to the roots of the plants and are absorbed by the plants.

Plants fixed horizontally on horizontal pipes with stoppers usually
It naturally bends upward due to its nature of growing upwards and grows along vertical cultivation boxes. The diagonal cut surface of the pipe is arranged so as to face downward, and by closing the pipe with the stopper made of the elastic foam, it is possible to prevent the culture liquid droplets from leaking through the pipe to the front of the cultivation box.

〔Example〕

The embodiment of the present invention generally shown in FIGS. 1 and 2 is
The cultivation box 1 is vertically supported by a frame (not shown), the culture solution tank 2 and the culture solution circulation pump 3 are arranged below it, and the whole is stored in a furniture-like box 4 so that only the front of the cultivation box 1 can be seen. It is the one.

The front surface of the cultivation box 1 is a mounting surface of the cultivation plate 5, and as shown in an enlarged view in FIG. 3, the cultivation plate 5 is superposed on the lattice-shaped support frame 6 and its four circumferences are superposed on the support frame 6. It is fixed by the fixing bolt 7 and the nut 8 in the closed state. Therefore, the individual cultivation plates 5 can be independently replaced by loosening the nut 8. The support frame 6 exposed portion 6a between the cultivation plates 5 can be fixed with a wooden decorative material (not shown) if desired.

As shown in FIGS. 4 and 5 with the cultivation plate 5 removed from the support frame 6, a large number of holes 10 are drilled in a plastic square plate 9 (260 mm × 260 mm). A short plastic pipe with one end cut diagonally 11
(Diameter 18 mm, length 40 mm) right angle cutting end 11a is fitted and adhered, and as shown in FIG. The cutting surface 12 is fixed to the support frame 6 with the posture facing downward. A plug 13 (not shown in the above figures) made of a silicone rubber foam is fitted to each pipe 11 from the right-angled cut end 11a side.

There is a spray nozzle 15 on the ceiling inside the cultivation box 1,
The culture solution in the culture solution tank 2 is pumped by the pump 3 via the pipe 16. Further, the bottom plate of the cultivation box 1 has a drainage port 17 in the center, and the drainage port is connected to the culture fluid tank 2 by a pipe 18.

Next, a method for planting seedlings will be described with reference to FIG. Remove the plug 13 from the pipe 11 and open the removed plug 13 at the cut 19 reaching the central shaft plug. If not cut, open it with a break. Then, the seedling 20 that had been grown in the nursery was inserted into the break of the stopper 13 and most of the root 21 was covered with the stopper 13.
It is arranged so that it is exposed from the tip of the stem, and the stem portion is clamped by the stopper 13. The seedling 20 is fixed to the pipe 11 when the plug 13 holding the seedling 20 is fitted into the pipe 11 while pushing the root 21 into the cultivation box 1. When the seedlings 20 are fixed on all the pipes 11 as described above, the surface of the cultivation box 1 is 20 seedlings.
(If desired, the seedlings may be left unfixed on some pipes 11, but in that case, the pipes 11 are also fitted with stoppers 13 for water stoppage.).

When the culture solution circulation pump 3 is operated and the culture solution in the culture solution tank 2 is pressure-fed to the spray nozzle 15, the culture solution is sprayed from the spray nozzle 15 and atomized into the cultivation box 1. The dropped culture solution droplets adhere to the roots 21 of the plant seedling 20 exposed in the cultivation box 1 and are absorbed by the seedling 20.
In other words, although the plug 13 is made of foam, it does not become a growing part of the root 21, but is used only for fixing the seedling 20 and stopping water. Liquid leakage to the front of the cultivation plate 5 via the pipe 11 is completely prevented by not only the water blocking action of the stopper 13 but also the action of the downwardly inclined cut surface 12 of the pipe 11 to guide the attached water downward. . The circulation pump 3 operates continuously according to the type of plant or intermittently using a timer.

Since the pipes 11 of the cultivation plate 5 are horizontal, the fixed seedlings 20 also initially face sideways, but they bend right upwards and grow along the vertical cultivation box 1.

Replanting of plants can be performed for each pipe 11 or each cultivation plate 5 at any time.

〔The invention's effect〕

Since the cultivating device of the present invention has the above-mentioned configuration and usage, it is possible to cultivate plants three-dimensionally, and to cultivate a large number of plants even when it cannot occupy a large floor area. It is possible to present in various modes. In addition, since the roots are extended in the space without using a cultivation bed, it is not only labor-saving to manage, but also lightweight, so there is no need to worry about the strength of the floor where the device is installed, and it is easy to move during cultivation. . It is easy to enhance the interior quality by applying a wooden exterior. Furthermore, since it is easy to partially or wholly change the cultivated plant species, it is extremely advantageous as an apparatus for indoor cultivation which requires more frequent updating than an outdoor garden.
