Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hydroponic cultivation bed for growing plants, and more particularly to an overturn prevention mechanism that maintains a properly planted state of plants.

[Conventional technology]

An example of a conventional hydroponic cultivation bed of this kind will be explained with reference to FIGS. 8 and 9.

FIG. 8 is a schematic perspective view of a conventional hydroponic cultivation bed;
FIG. 9 is a sectional view of the planting plate.

In these figures, 1 is a hydroponic cultivation bed,
The structure is such that a nutrient solution flows through the bed 1.

A cultivation panel 2 is arranged on the hydroponic cultivation bed 1, and a large number of holes (planting holes) 3 for planting plants are arranged in the panel 2. A plate mounting portion 4 is formed around each planting hole 3 .

A plant body 6 is inserted into the planting hole 3 via the planting plate 5 and is planted therein.

The planting plate 5 includes a boss portion 5A having an outer diameter smaller than the inner diameter of the planting hole 3, and a flange 5B provided above the boss portion 5A. The plant body 6 is held on the inner diameter portion of the boss portion 5A via a holding member (medium) 7.

In the planting state, the boss portion 5A of the planting plate 5 is inserted into the planting hole 3, and the flange 5B is inserted into the panel 2.
placed on the surface.

[The problem that the idea attempts to solve]

The above conventional planting plate allows the plants 6 to be easily taken in and out of the planting hole 3 while being protected by the planting plate 5, making it easy to observe the rhizosphere of the plants 6 and measure the fresh weight of the plants 6. It has the advantage of not damaging the roots when taking it in and out.

However, when plants such as vegetables grow tall or bear fruits and the above-ground parts become heavy, the planting plate 5 may float as shown in Figure 10. , and sometimes fell. Since such a situation leads to inhibition of plant growth, some kind of countermeasure is desired.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a hydroponic cultivation bed in which plants can be planted without floating or falling over.

[Means to solve the problem]

In order to achieve the above object, the present invention arranges horizontal grooves facing each other around the planting hole of the panel in this type of hydroponic cultivation bed, and makes the groove width of each horizontal groove larger than the thickness of the flange of the planting plate. On the other hand, the flanges of the planting plate can be set between the pair of lateral grooves, and after being set, when rotated in a predetermined direction, the flanges of the planting plate have a shape that locks into the lateral grooves, and this locking provides a mechanism for preventing the plant from falling over. Configure.

[Effect]

When inserting a plant body into a planting hole of a cultivation panel via a planting plate, the flanges of the planting plate are oriented in advance so that they can be set between the horizontal grooves of the pair of plates.

In this state, when the boss part of the planting plate is inserted into the planting hole and the planting plate is rotated when the flange is positioned between the pair of horizontal grooves, a part of the flange will enter into each horizontal groove and become locked. Stop.

As a result, when the plants are in a planted state, the flanges of the planting plate are engaged with the horizontal grooves on the panel side. Therefore, even if the plant is subjected to a force that tends to cause it to topple over, it is possible to reliably prevent the plant from lifting up or falling over.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 6.

In these figures, 10 is a hydroponic cultivation bed, which consists of a bed body 10A for supplying nutrient solution and a panel 10B provided on the top of the bed body 10A.
A large number of planting holes 11 are arranged in an array.

On the upper surface of the panel 10B, a pair of lateral grooves 12 are arranged to face each other around the planting holes 11, respectively. In addition,
The lateral grooves 12 are shown with diagonal lines in FIGS. 2 and 4 for convenience. The width of the lateral groove 12 is larger than the thickness of a flange 15B of the planting plate 15, which will be described later. The lateral grooves 12 in this embodiment are grooves that are arranged parallel to each other along the arrangement of the planting holes 11, and a space S in which the flange 15B of the planting plate 15 is set is secured between the opposing lateral grooves 12.

Here, an example of forming the lateral grooves 12 will be explained with reference to FIG. 6.

In FIG. 6, a plurality of strip-shaped vinyl chloride boards 13 and 14 of different sizes, sizes, and widths are prepared, and the panel 10B
With the area around the planting hole 11 (flange mounting space S) in between on the top surface, stack the vinyl boards 14 with the smaller width on the bottom and the vinyl board 13 with the larger width with the center lines aligned. By joining, horizontal grooves 12 surrounded by the vinyl plates 13 and 14 are formed on both sides of the vinyl plate 14. The joining method for the joining part is adhesion using adhesive or thermal welding using heat.
In addition, although the above groove forming member is made of vinyl chloride, it may be made of other materials, and other joining methods may be used as long as the joining method provides strength sufficient to support the weight of the plant. .

15 is a planting plate, as shown in Figure 5,
It is composed of a boss portion 15A and a flange 15B.
The specifications of the boss portion 15A for the planting hole 11 are the same as those of the conventional one, and its outer diameter is smaller than the inner diameter of the planting hole 11, and the inner diameter has an inner diameter portion in which the culture medium (holding member) 18 can be inserted. The medium 18 protects and retains the root base of the plant body 6 or its vicinity,
For example, it is made of polyurethane, rock wool, etc.

The flange 15B is disposed above the boss portion 15A. Although various shapes can be considered for the shape of the flange 15B, in this embodiment, it is rectangular.
As shown in FIG. 4, the width l1 of the flange 15B is somewhat smaller than the distance l3 between the opposed ends of the lateral grooves 12, but the diagonal dimension l of the flange 15B is
2 is set larger than l3.

In such a configuration, in order to plant the plant 6 on the cultivation panel 10B, the plant 6 is attached to the boss portion 15A via the holding member 18 in advance, and the flange 15B is positioned at the dotted line 15B' in FIG. The left and right sides of 15B are aligned so that they are substantially parallel to the band member 13. In this state, the flange 15B has a space S between the horizontal grooves 12, 12.

As described above, plant body 6 is placed in hydroponic cultivation bed 1.
It is planted on the planting plate 0, but in the planting state, it is planted on the planting plate 1.
5 is locked by the flange 15B and the horizontal groove 12 to prevent it from coming off, so even if the plant 6 grows or bears fruit, the plant 6 is reliably prevented from falling over.

Plant body 6 in established state is grown in hydroponic cultivation bed 10
When taking it out, the planting plate 15 is rotationally displaced in the opposite direction to that at the time of installation, and the flange 15B is returned to the dotted line position 15B' in FIG. Thereby, the latching of the flange 15B to the horizontal groove 12 is released, and the planting plate 15 can be pulled out, and the plant body 6 can be removed from the panel 10B of the hydroponic cultivation bed 10 while being protected by the planting plate 15.

FIG. 7 shows a second embodiment of the present invention, which differs from the first embodiment in the shape of the planting hole 11 in the panel 10B. The width is larger than the diameter of the boss portion 15A of the planting plate 15, and the width l1 of the flange 15B and the opposing line dimension l
It is made smaller than 2.

In this embodiment as well, similar to the first embodiment, the flange 15B and the horizontal groove 12 are engaged to reliably prevent the planting from falling during planting. You can freely change the planting density without changing the number. Therefore, even when changing the planting density, there is no need for replanting work, which has the advantage of making plant growth and management even easier.

In the above embodiment, the horizontal grooves 12 are formed on the top surface of the cultivation panel 10B, but the horizontal grooves 12 are formed on the top surface of the cultivation panel 10B.
It is also possible to set it on the lower surface of the panel 10B, and in this case, the flange 15B may be rotated and displaced through the planting hole 11 at the lower surface position of the panel 10B.

Moreover, although the flange 15B is illustrated as having a rectangular shape, and the planting hole 11 is illustrated as having a circular shape and a band shape, the present invention is not limited to this, and similar effects can be expected with other shapes.
