<First Embodiment>
FIG. 1 is a perspective view showing the appearance of a hydroponics pot used in the hydroponic cultivation apparatus according to the present embodiment. The hydroponics pot 1A in the present embodiment is used for hydroponics of leafy vegetables such as lettuce, for example. Moreover, FIG. 2 is the top view which looked at the float board used for the hydroponic cultivation apparatus which concerns on this embodiment from the upper surface.

  The float board 2 is provided on the water surface of hydroponics. As shown in FIG. 2, the float plate 2 is formed with a plurality of insertion holes 2a for inserting the hydroponics pot 1A at regular intervals. In this embodiment, the float plate 2 is made of a material that has buoyancy with respect to water for hydroponics, such as foamed polystyrene that is made into a porous shape by dispersing gas in a synthetic resin, for example. In addition, as the float board 2, an inside is hollow, a side is formed with resin, such as a plastics, and it may have buoyancy with respect to the water for hydroponics.

  As shown in FIG. 1, the hydroponics pot 1 </ b> A includes a container 11 and a support 12. The portion of the container 11 of the hydroponics pot 1 </ b> A is fitted into the insertion hole 2 a, and the support 12 supports the container 11 on the upper surface of the float plate 2. Hereinafter, the details of the hydroponics pot 1A will be described.

  FIG. 3 is a plan view of the hydroponics pot 1A shown in FIG. 1 as viewed from above. FIG. 4 is a side view of the hydroponics pot 1A shown in FIG. FIG. 5 is a cross-sectional view illustrating a cut surface taken along line II in FIG. In the present embodiment, the container 11 has a substantially rectangular parallelepiped cylindrical shape in which an upper surface opening 112a and a lower surface opening 111a (see FIG. 5) are formed on the upper surface and the lower surface. Have. As shown in FIGS. 4 and 5, a rectangular window portion 11 b is formed on each side surface of the container 11. In the present embodiment, as the medium, for example, a medium that has water retention properties such as a urethane medium or a rock wool medium formed of a resin such as polyurethane and is shaped so as to be accommodated in the accommodation space is used.

  As shown in FIG. 1, the support 12 is connected to the upper surface opening 112 a of the container 11. The support 12 has a light shielding part 121 and a support part 122. As shown in FIG. 1 and FIG. 3, the light shielding portion 121 is configured by a plate-like member having an octagonal shape including eight sides A to H, and an upper surface of the container 11 at a connection portion with the container 11. It has a hole 12a that is substantially the same size as the opening 112a.

  The support part 122 has a substantially octagonal cylindrical shape in which the frame bodies 122A to 122H are connected so as to surround each side (A to H) of the light shielding part 121. Each frame 122A-122H has a ventilation window 12b (ventilation hole) as shown in FIG. Moreover, each frame 122A-122H of the support part 122 is comprised so that the height from the upper surface (surface) of the light-shielding part 121 may become substantially the same height T1, as shown in FIG. Further, each of the frames 122A to 122H of the support portion 122 is configured such that the height from the lower surface (back surface) of the light shielding portion 121 is different from the adjacent frames. In the present embodiment, among the sides A to H shown in FIG. 3, the protrusions 122 a that protrude to the lower surface side of the light shielding portion 121 are formed in the frames 122 B, 122 D, 122 F, and 122 H on the sides B, D, F, and H. Have. Therefore, as shown in FIG. 4 and FIG. 5, the support 12 is formed on the side A, C, E, G between the protrusions 122 a formed on the support 122 on the lower surface side of the light shielding part 121. It has a recess 12c.

  That is, the support 12 has a hollow space that is connected to the accommodation space in the accommodation body 11 through the hole 12a of the light shielding portion 121 and supports the grown plant in the support portion 122, and 2 on the lower surface side of the light shielding portion 121. There are four recesses 12c in the opposite side of the set.

  Here, the figure which looked at the state by which the pot 1A for hydroponics was inserted in the insertion hole 2a of the float board 2 from the side surface direction is shown in FIG. As shown in FIG. 6, the width H11 of the container 11 is smaller than the width h1 of the insertion hole 2a of the float plate 2, and the width H12 of the support 12 is larger than the width h1 of the insertion hole 2a. That is, the cross-sectional area of the container 11 is smaller than the area of the insertion hole 2a, and the cross-sectional area of the support 12 is larger than the area of the insertion hole 2a. 12 is supported.

  Moreover, as shown in FIG. 6, in this embodiment, the window part 11b in the container 11 is located in height H2 from the lower surface of the light-shielding part 121, and height H2 is from thickness h2 of the float board 2. As shown in FIG. It is set large. Thereby, the window part 11b of the container 11 is arrange | positioned below the lower surface of the float board 2. FIG. Therefore, in the container 11, the container 11 is fixed so that the plant root grown above the window part 11 b is not exposed to water, and the root part of the plant in the window part 11 b is exposed to water. The As a result, water and nutrients contained in the water can easily enter the root portion of the plant from the window portion 11b, and the growth of the plant can be promoted.

  Moreover, since the storage space of the container 11 in which the medium is stored has a substantially rectangular parallelepiped shape, the medium is stored substantially uniformly. That is, for example, in the case of a tapered storage space in which the lower cross-sectional area is smaller than the upper cross-sectional area, the medium stored below is compressed by the medium stored above, and the medium is uniformly distributed in the storage space. Can not be stored. In that case, the root of the plant becomes difficult to extend downward, which affects the growth of the plant. On the other hand, in this embodiment, since the upper and lower cross-sectional areas of the accommodation space of the container 11 are substantially the same, the lower culture medium is not easily compressed, and the growth of plant roots is not hindered. Moreover, since the accommodation space of the container 11 of the hydroponics pot 1A has a substantially rectangular parallelepiped shape, for example, even when a plurality of hydroponics pots 1A are put in water and washed, the hydroponics pots 1A are mutually connected. The cleaning work is made more efficient without being superposed. Moreover, since the container 11 has a substantially rectangular parallelepiped shape, the container 11 is less likely to rotate or tilt in the insertion hole 2a than in the case of a cylindrical shape, and the container 11 can be maintained in a stable state.

  Further, in the state where the hydroponics pot 1A is inserted into the float plate 2, the light shielding portion 121 of the support 12 is disposed substantially horizontally with respect to the upper surface of the float plate 2, as shown in FIG. . A gap is formed between the rear surface of the light shielding part 121 and the upper surface of the float plate 2 by the height of the protrusion 122a. However, in the vicinity of the insertion hole 2a, light such as natural light or LED is shielded. Is shielded from light. Therefore, it becomes difficult for light to enter from the insertion hole 2a, and the generation of algae due to photosynthesis in water under the float plate 2 can be suppressed.

  Further, since the support portion 122 of the support 12 is formed at a certain height from the upper surface of the float plate 2, the plant extending from the hole 12 a of the support 12 is supported by the hollow space of the support portion 122. Thereby, even if the leaf of a plant spreads outside the support portion 122, the leaf is hardly brought into contact with the upper surface of the float plate 2, and the alteration of the leaf is suppressed.

  When the support part 122 is not provided, since the grown plant leaf and the float plate 2 overlap, moisture is generated between the plant leaf and the float plate 2, causing the plant leaf to be altered. Become. In the present embodiment, the leaves of the plant grown outside the support portion 122 and the float plate 2 do not directly overlap with each other because the plant leaf grown by the support portion 122 is supported. Moisture during is suppressed. Furthermore, in this embodiment, since it has the ventilation window 12b in the side surface of the support body 12, air permeability improves and the alteration of the leaf of a plant is suppressed.

  Further, when the hydroponics pot 1A is attached to or detached from the float plate 2 using a device for attaching or removing the hydroponics pot to the insertion hole 2a (hereinafter referred to as an attaching / detaching device), for example, FIG. As shown in FIG. 2, the arm 3 of the attachment / detachment device can be inserted and lifted from the x-axis or y-axis direction in the figure into the recess 12c formed on the back surface side of the light-shielding part 121 in the support 12. That is, the arm 3 is received by the recess 12c that functions as an arm receiving portion. Therefore, compared with the case where the recessed part 12c is not formed in the back surface side of the light-shielding part 121 in the support body 12, the attachment or detachment of the hydroponics pot 1A in the insertion hole 2a can be performed easily. Moreover, according to the growth process of the plant cultivated in the hydroponics pot 1A, to improve the working efficiency when transplanting the hydroponics pot 1A to another float plate with different intervals between the insertion holes 2a. Can do.

For example, the light shielding part 121 may have a polygonal shape having symmetry such as a hexagonal shape or a decagonal shape, and the support part 122 may be constituted by the polygonal cylindrical shape. FIG. 14 is a plan view illustrating the upper surface of the hydroponics pot when the support 12 has a hexagonal prism shape. In this example, the light shielding part 321 has a hexagonal plate-like member. In addition, the support portion 322 includes frame bodies 322A to 322F that surround each side of the light shielding portion 321. Of the frame bodies 322A to 322F, the frame bodies 322F and 322C may have a protrusion 122a on the back side of the light shielding section 321. Therefore, in this case, in the support body 12, a recess formed between the frame body 322 </ b> F and the frame body 322 </ b> C functions as an arm receiving portion.

(2) Although the example which has rectangular shape demonstrated the light-shielding part 221 in 2nd Embodiment mentioned above, polygonal shapes, such as a hexagon and an octagon, may be sufficient, and circular shape may be sufficient. In this case, the plate-like member 222B of the support portion 222 may have a shape similar to the shape of the light shielding portion 221.

(3) The container 11 of the first embodiment described above has been described with an example having one rectangular window portion 11b on each side surface. Moreover, the container 21 of 2nd Embodiment mentioned above demonstrated the example which has eight rectangular-shaped window parts 21b in each side. In this modification, you may comprise the window parts 11b and 21b of these containers 11 and 21 as follows. The number of the window parts 11b and 21b which each side surface of the accommodating bodies 11 and 21 has is not limited to the number illustrated by 1st Embodiment and 2nd Embodiment. That is, the container 11 may have the same number of the plurality of window portions 11b on each side surface. The container 21 may have one window portion 21b on each side surface. The containers 11 and 21 may have a different number of window portions 11b and 21b for each side surface.

  Furthermore, in the accommodating bodies 11 and 21, the shape of the window portions 11b and 21b is not limited to a rectangular shape, and may be an arbitrary shape such as a circle or a polygon. Moreover, all the window parts 11b and 21b may be the same size, and each may be different sizes. Moreover, the accommodating bodies 11 and 21 do not need to have the window parts 11b and 21b in each side surface.

(4) In 1st Embodiment and 2nd Embodiment mentioned above, although the containers 11 and 21 demonstrated the example which has a substantially rectangular parallelepiped shape, it is polygonal prismatic shapes, such as a pentagon and a hexagon, for example. Also good.

(5) Although the support body 12 of 1st Embodiment mentioned above demonstrated the example which has one ventilation window 12b for every side surface of the support part 122, you may comprise as follows. For example, as shown in FIG. 15, the support part 422 of the support body 42 may be configured by connecting side walls 422A to 422H that do not have ventilation windows. In addition, a plurality of ventilation windows may be provided on each side surface, or each side surface may be formed in a mesh shape to have a ventilation hole.

(6) Although the support part 222 of 2nd Embodiment mentioned above was an example in which the part P which the plate-shaped member 222b protruded from the upper end of the prismatic member 222A functions as a collar part, it may comprise as follows.

As shown in FIG. 16, in this modification, a rectangular flange 222 </ b> C is connected to the upper four sides of the prismatic member 222 </ b> A in the support portion 222 so as to be substantially parallel to the light shielding portion 221. Even in such a configuration, as in the second embodiment, since the leaves of the plant spreading outside the support 22 can be received by the butt portion 222C, the grown leaves do not come into contact with the upper surface of the float plate 2. Can be. Moreover, since the recessed part (illustration omitted) is formed between these collar parts 222C and the light-shielding part 221, the arm 3 part of the attachment / detachment apparatus mentioned above is inserted in each recessed part, and the pot 1C for hydroponics can be moved. it can.

  In the above-described example, the ribs 222C are independent on all sides, but the ribs 222C may be provided on only two opposite sides. As shown in FIG. 16, when the ribs 222C are provided on all sides, the arm 3 of the attachment / detachment device can be inserted into the recess from both the x-axis direction and the y-axis direction of FIG. In the case of having the flange 222C only on the side, the arm 3 is inserted only in either the x-axis direction or the y-axis direction. Therefore, in this case, the convenience is reduced as compared with the case of FIG. 16, but it is not necessary to provide the ribs 222C on all sides, and the manufacturing cost of the hydroponics pot 1C can be suppressed.

(7) In 1st Embodiment mentioned above, each frame which comprises the support part 122 of the support body 12 has the protrusion part 122a so that the height of the back surface side of the light-shielding part 121 may differ from the adjacent frame body. However, the protrusion 122a may not be provided. FIG. 17A is a side view of a hydroponics pot 1D according to the present modification. As shown in FIG. 17A, the height of the rear surface side of the light shielding part 121 is substantially the same in each frame of the support part 522. That is, in the support body 52, the concave portion 12 c that functions as an arm receiving portion may not be formed on the back surface side of the light shielding portion 121.

  Further, in the above-described second embodiment, the example in which the support portion 222 of the support body 22 includes the prismatic member 222A and the plate-like member 222B has been described.
