Description

The present invention relates to a cultivation container and a cultivation device.

Plant cultivation devices are known that have plant placement sections (or cultivation pots) for planting plants arranged vertically. For example, they may include a vertically extending nutrient solution pipe for supplying nutrient solution, a vertically extending plant pipe for planting cultivated plants, and a vertically extending growth light source for irradiating cultivated plants with artificial light. The plant pipe has a branch pipe, which is a pipe with a plant placement section for placing cultivated plants installed inside the tip, extending diagonally upward at an angle of 20 to 60 degrees relative to the plant pipe to form a space between the plant pipe and the upper surface of the branch pipe. One or more branch pipes are provided in a vertical straight line at predetermined height intervals, and nutrient solution supply pipes are used to supply nutrient solution from the inside of the nutrient solution pipe to the inside of the branch pipe. A known plant cultivation device is equipped with a supply means, and the growth light source, branch pipe, plant pipe, and nutrient solution pipe are arranged in a straight line in this order so that artificial light from the growth light source is irradiated onto the branch pipe, with the plant pipe and nutrient solution pipe being installed at a distance from each other. The nutrient solution supply means is a nutrient solution supply pipe connecting the nutrient solution pipe and branch pipe, one end of the nutrient solution supply pipe is connected to the nutrient solution pipe, and the other end of the nutrient solution supply pipe, which is located in the space between the plant pipe and the upper surface of the branch pipe, is connected to the upper surface of the branch pipe. The nutrient solution in the nutrient solution pipe flows into the branch pipe connected to the plant pipe via the nutrient solution supply pipe.

<Embodiment>
FIG. 1 is a diagram schematically illustrating a cultivation device according to an embodiment.

The cultivation device 1 of the first embodiment has a support 2, a nutrient solution distribution unit 3, a plurality of cultivation pots 4, a cultivation pot support unit 5, a liquid storage unit 6, a rotation drive unit 7, and a frame body 8.
1, for ease of understanding, some of the cultivation pots 4 and cultivation pot supports 5 are omitted from the illustration. Also, the inside of the support 2 is shown in a see-through manner.
The cultivation device 1 utilizes free fall due to the action of gravity to supply a nutrient solution, which is a mixture of nutrients suitable for plant growth and water, to the cultivation pots 4.

As shown in Fig. 1, in a plan view (viewed from the top to the bottom of the page in Fig. 1), the cultivation device 1 has a support post 2 disposed in the center, and a plurality of cultivation pot supports 5 disposed so as to surround the support post 2 (in a ring shape in a plan view). For example, eight cultivation pot supports 5 can be disposed at equal intervals. The number of cultivation pot supports 5 is not limited to eight. The spacing between the cultivation pot supports 5 is not limited to equal intervals, but arranging them at equal intervals is preferable in terms of lighting and appearance.
The support column 2 is hollow and is made of, for example, resin or metal such as stainless steel. The diameter of the support column 2 is not particularly limited, but is, for example, 40 mm.
The cultivation pot support portion 5 is a long member that supports the cultivation pot 4. The cultivation pot support portion 5 also forms a flow path for supplying the nutrient solution to the cultivation pot 4.

A plurality of cultivation pots 4 can be arranged along the longitudinal direction of the cultivation pot support part 5. Plants to be cultivated are placed in the cultivation pots 4. The structure of the cultivation pots 4 will be described in detail later.
2 is a diagram illustrating the cultivation pot support part of the embodiment, in which the cultivation pot 4 is not shown.

The cultivation pot support part 5 is a hollow, elongated member resembling a horseshoe in plan view, with three of its four longitudinal sides enclosed and one open. Examples of materials that can be used to construct the cultivation pot support part 5 include resin. The cultivation pot support part 5 of this embodiment is flexible. It is preferable that it be able to contract slightly left and right on the page. The open side of each cultivation pot support part 5 is located on the opposite side (i.e., the front side) from the side facing the support 2.

The cultivation pot support part 5 is placed on a base 9. The base 9 has a hole 91 in the center through which the support post 2 passes. A bearing is placed in the hole 91, allowing the base 9 to rotate around the support post 2 while the support post 2 is fixed. In this embodiment, the support post 2 does not rotate, but the base 9 and cultivation pot support part 5 rotate around the support post 2.

The base 9 has a frame 92 at the portion where the cultivation pot support part 5 is placed, which surrounds the end of the cultivation pot support part 5 to support the end of the cultivation pot support part 5. A hole 93 having a diameter smaller than the diameter of the end of the cultivation pot support part 5 is provided in the frame 92, and liquid that passes through the inside of the cultivation pot support part 5 passes through this hole 93 and falls into the liquid storage part 6.
A support part 21 for supporting the cultivation pot support part 5 is attached to the support pole 2 .
FIG. 3 is a diagram illustrating a support portion according to the embodiment.

The support part 21 has a bearing part 211 that surrounds the support pole 2 and is fixed to the support pole 2, and clips 212 that extend from the bearing part 211 and clamp each cultivation pot support part 5. By providing the support part 21, the stability of the cultivation pot support part 5 is increased.
Returning to FIG. 1, the description will be continued.

A supply pipe 22 is arranged inside the support 2, through which the nutrient solution to be supplied to the plants flows. The diameter of the supply pipe 22 is not particularly limited, but is, for example, 13 mm. The inner diameter of the supply pipe 22 is not particularly limited, but is, for example, 9 mm. A relay pipe 23 is arranged at the upper end 22a of the supply pipe 22. The diameter of the relay pipe 23 is not particularly limited, but is, for example, 18 mm. The inner diameter of the relay pipe 23 is slightly larger than the 13 mm diameter of the supply pipe 22. This allows the end of the relay pipe 23 to be inserted into the supply pipe 22. Furthermore, when the supply pipe 22 is inserted into the relay pipe 23, the relay pipe 23 can rotate around the supply pipe 22. A nutrient solution distribution unit 3 is arranged at the other end of the relay pipe 23.

A gutter 51 is located at the end 5a of the cultivation pot support 5. The nutrient solution that passes through the supply pipe 22, relay pipe 23, nutrient solution distribution unit 3, and gutter 51 is supplied to the cultivation pot support 5.

The liquid reservoir 6 is filled with nutrient solution. A pump 61 is disposed in the liquid reservoir 6. The pump 61 pumps up the nutrient solution filled in the liquid reservoir and supplies it to the supply pipe 22.
The rotation drive unit 7 drives the nutrient solution distribution unit 3 to rotate.
FIG. 4 is a diagram illustrating the nutrient solution distribution unit and the rotation drive unit according to the embodiment.
The nutrient solution distribution section 3 supplies the nutrient solution flowing out from the relay pipe 23 to the upper end of the cultivation pot support section 5.
The nutrient solution distributing section 3 has an inlet 31 , a branching section 32 , and a supported section 33 .

The inlet 31 is fixed to the end of the relay pipe 23. The nutrient solution is pumped up by the pump 61, passes through the supply pipe 22 and relay pipe 23, and reaches the upper end of the support 2. The inlet 31 and the branch section 32 are internally connected.

The number of branch sections 32 is determined according to the number of cultivation pot supports 5. In this embodiment, eight cultivation pot supports 5 are arranged, so there are eight branch sections 32, but the number of branch sections 32 is not limited to eight. The nutrient solution that flows into the inlet 31 passes through each of the eight branch sections 32 and flows out from the outlet 321 of each branch section 32.

It is also possible to provide a valve or the like midway through the branching parts 32 so that the supply of nutrient solution to the cultivation pot support parts 5 is stopped for some of the branching parts 32. In this way, it is possible to provide both branching parts 32 that supply nutrient solution to the cultivation pot support parts 5 and branching parts 32 that do not supply nutrient solution.
A gear shaft 74 that transmits the power of the rotation drive unit 7 is attached to the supported portion 33 .
The rotation drive unit 7 has a motor 71 .
The motor 71 is supported by a drive unit support part 81 attached to the frame body 8 and is positioned above the nutrient solution distributing part 3 .
A gear 73 is attached to the motor 71. The gear 73 is engaged with a gear shaft 74. The gear shaft 74 is inserted into the supported portion 33.
The motor 71 in this embodiment transmits power to the supported part 33 of the nutrient solution distributing part 3 via a gear 73 and a gear shaft 74 .
The rotation speed of the nutrient solution distributing unit 3 is not particularly limited, but is, for example, 3 revolutions/m.
Returning to FIG. 1, the description will be continued.

The frame body 8 supports a drive unit support part 81. The frame body 8 also has a light source support part 82 that supports the light source 10. The light source 10 in this embodiment is arranged along the longitudinal direction of the cultivation pot support part 5 so as to surround the cultivation pot support part 5. The arrangement interval of the light sources 10 in this embodiment is not particularly limited, but for example, is at 90 degree intervals around the support 2. The light source 10 is not particularly limited, but examples thereof include fluorescent lamps and LEDs. The light source 10 may be omitted.
<Cultivation pot>
As described above, a plurality of cultivation pots 4 can be arranged along the longitudinal direction of the cultivation pot support portion 5 .
5 and 6 are diagrams illustrating the cultivation pot according to the embodiment.
The cultivation pot 4 is supported by a cultivation pot support part 5 and takes in a part of the nutrient solution flowing through the cultivation pot support part 5 .
The cultivation pot 4 has a cup (plant placement portion) 41 and a pot body 42. The cup 41 is detachable from the pot body 42.
7 and 8 are diagrams illustrating the cup according to the embodiment.

The cup 41 has a first opening 41a, a plant placement portion 41b, a nutrient solution guide portion 41c, a pond 41d, a second opening 41e, and an engagement portion 41f. In this embodiment, the plant placement portion 41b and the pond 41d have no boundary and are formed integrally. A partition of some kind may be provided between the plant placement portion 41b and the pond 41d.

Plant seedlings are placed on the plant placement section 41b. When cultivating plants, seeds may be planted in a sponge medium (not shown) placed inside the plant placement section 41b, and the plants may then be cultivated. The nutrient solution dripping from the nutrient solution guide section 41c permeates the sponge medium, supplying the nutrient solution to the plants.

The nutrient solution guide portion 41c is the part that the user grasps when attaching or detaching the pot body 42 and the cup 41. This nutrient solution guide portion 41c also functions as a flow path that supplies nutrient solution to the plant placement portion 41b.

The pond 41d is a portion for storing nutrient solution. Nutrient solution that overflows from the pond 41d flows out through the second opening 41e. The volume of the pond 41d is not particularly limited, but is, for example, 50 cc.

The engaging portion 41f has a spherical dowel 41f1 and a plate-like protruding portion 41f2 protruding from the nutrient solution guide portion 41c. The engaging portion 41f engages with a slit (engaged portion) of a shape provided in the pot body 42, thereby forming a simple locking mechanism.
9 and 10 are diagrams illustrating the pot body of the embodiment.
The pot body 42 has a protrusion 42a, a storage portion 42b, a connecting portion 42c, and a protrusion 42d.

The protrusion 42a is provided along the longitudinal direction of the pot body 42. It fits into the guide rail (described below) of the cultivation pot support part 5. This allows the pot body 42 to be supported movably along the longitudinal direction of the cultivation pot support part 5.

The storage section 42b is designed to correspond to the shape of the cup 41 and stores the cup 41. The storage section 42b has an opening 42b1 that corresponds to the opening 41a of the cup 41, a bottom support section 42b2 that supports the bottom of the cultivator, and a side support section 42b3 that supports the sides of the cultivator.

The storage portion 42b also has a slit (engaged portion) 42b4 shaped to correspond to the engaging portion 41f on the cup 41. The slit 42b4 includes an insertion portion 42b41 through which the dowel 41f1 and protrusion 41f2 pass, a contact portion 42b42 against which the protrusion 41f2 abuts, a step portion 42b43 over which the dowel 41f1 overcomes as the protrusion 41f2 slides toward the abutment portion 42b42 and approaches the abutment portion 42b42, and a dowel storage portion 42b44 that accommodates the dowel 41f1 when the protrusion 41f2 abuts the abutment portion. The sliding contact of the protrusion 41f2 with the abutment portion 42b42 accommodates the dowel 41f1 in the dowel storage portion 42b44, forming a simple locking mechanism. This prevents the cup 41 from easily detaching from the pot body 42. Furthermore, when the cultivation device 1 is in use, the slit 42b4 is positioned at an angle when the cultivation pot 4 is placed on the cultivation pot support portion 5. This prevents the cup 41 from easily coming off the pot body 42.

When it is desired to remove the cup 41 from the pot body 42, the dowel 41f1 is released from the dowel receiving portion 42b44 by applying a certain amount of force in a direction parallel to the slit. This allows the cup 41 to be removed from the pot body 42.
The connecting portion 42c is shaped so as to be connectable to the upper portion of the cultivation pod 4 disposed below the cultivation pot 4.

The protrusion 42d is provided along the longitudinal direction of the pot body 42. The length of the protrusion 42d in the protruding direction is, for example, 2 mm. The function of the protrusion 42d will be described later.
Returning to FIG. 6, the description will be continued.

When the cup 41 is attached to the main body, an opening 44 is formed between the upper part of the nutrient solution guide part 41c and the pot main body 42. A part of the nutrient solution flowing through the cultivation pot support part 5 flows from this opening 44 into the plant placement part 41b.
Next, the arrangement and structure of the cultivation pots 4 will be described.
FIG. 11 is a plan view illustrating the arrangement and structure of the cultivation pot according to the embodiment.

Guide rails (grooves) 52 are provided along the longitudinal direction at both ends of the opening of the cultivation pot support part 5. The convex part 42a of the pot body 42 fits into the guide rails 52, thereby supporting the cultivation pot 4 on the cultivation pot support part 5. When the convex part 42a is fitted into the guide rails 52, the guide rails 52 clamp the convex part 42a, thereby allowing the cultivation pot support part 5 to clamp the cultivation pot 4. Friction generated between the guide rails 52 and the convex part 42a prevents the cultivation pot 4 from moving against its own weight even when a plant is placed in the cultivation pot 4 and the pond 41d is filled with nutrient solution. This structure allows the cultivation pot 4 to be placed at any position on the cultivation pot support part 5.
<Example of usage>
Next, an example of how to use the plant cultivation device 1 will be described.

The user attaches the cup 41 to the pot body 42. Then, the convex portion 42a of the pot body 42 is fitted into the guide rail 52. Examples of fitting methods include inserting the convex portion 42a into the guide rail 52 from the end of the cultivation pot support part 5, or slightly bending the guide rail 52 of the cultivation pot support part 5 and screwing the convex portion 42a into it.
Next, the user places the plant seedling on the plant placement portion 41 b of the cup 41 .
Next, the user drives the motor 71. This causes the nutrient solution distributing unit 3 and the cultivation pot supporting unit 5 to rotate around the support pole 2.

Next, the user operates the pump 61. This causes the pump 61 to pump up the nutrient solution stored in the liquid storage section 6 and supply it to the lower end of the supply pipe 22 via a pipe or the like. The nutrient solution passes through the supply pipe 22 and the relay pipe 23, and then flows into the inlet 31 of the nutrient solution distribution section 3. As described above, the nutrient solution that flows into the inlet 31 passes through each of the eight branch sections 32 and flows out from the outlets 321 of the branch sections 32. The nutrient solution that flows out from each outlet 321 passes through the troughs 51 and flows into the cultivation pot support section 5.
FIG. 12 is a diagram illustrating the flow of nutrient solution according to the embodiment.
In FIG. 12, an example of the flow of the nutrient solution is indicated by dotted arrows.

A portion of the nutrient solution that flows into the cultivation pot support section 5 flows down the nutrient solution guide section 41c of the uppermost cultivation pot 4 placed on the cultivation pot support section 5 into the plant placement section 41b and pond 41d.

12 shows a container 11 capable of accommodating a plant. The shape of the side of the container 11 corresponds to the opening 42b1 of the pot body 42, and the side of the container portion 10 engages with the opening 42b1. This allows the plant to be stably placed on the plant placement portion 41b.
Furthermore, a portion of the nutrient solution flows down the cultivation pot support portion 5 into the cultivation pot 4 below.

When a certain amount of nutrient solution flows into the pond 41d, the nutrient solution overflows from the pond 41d. The overflowing nutrient solution flows out through the second opening 41e, runs down the outer surface 41g of the cup 41, and falls to the bottom.

Figure 13 is a diagram explaining the flow of nutrient solution in this embodiment. To make the explanation easier to understand, in Figure 13, the upper cultivation pot is referred to as cultivation pot 4a, and the lower cultivation pot is referred to as cultivation pot 4b.

In this embodiment, when the cultivation pots 4a and 4b are attached to the cultivation pot support 5, the nutrient solution guide 41c blocks the outer surface 41g in a plan view (viewed from the top to the bottom of the page) (see also Figure 11; in Figure 11, the positions of the second opening 41e and the outer surface 41g are indicated by dotted lines). As a result, some or most of the nutrient solution that flows out of the second opening 41e of the upper cultivation pot 4a, runs down the outer surface 41g, and falls to the bottom strikes the nutrient solution guide 41c of the lower cultivation pot 4b, then flows down the nutrient solution guide 41c of the cultivation pot 4b and into the plant placement section 41b and the pond 41d. Then, some or most of the nutrient solution that flows out of the second opening 41e of the cultivation pot 4b, runs down the outer surface 41g, and falls to the bottom strikes the nutrient solution guide 41c of the lower cultivation pot 4 (not shown). In this way, the nutrient solution is supplied in order from the upper cultivation pot 4a to the lower cultivation pot 4b.

The nutrient solution that reaches the lower end of the cultivation pot support part 5 passes through the hole 93 and flows into the liquid storage part 6. The nutrient solution that flows into the liquid storage part 6 is again pumped up by the pump 61 and supplied to the supply pipe 22.

As described above, the cultivation device 1 of this embodiment includes a cup 41 having a first opening 41a, a plant placement portion 41b on which a plant is placed, a nutrient solution guide portion 41c that guides nutrient solution falling from the flow path of the cultivation pot support portion 5 to the plant placement portion 41b, a pond 41d that stores fluid flowing in from the nutrient solution guide portion 41c, and a second opening 41e that drains nutrient solution overflowing from the pond 41d into the flow path. The pot body 42 includes a bottom support portion 42b2 and a side support portion 42b3 that engage with the cup 41 and a convex portion 42a attached to the cultivation pot support portion 5 that forms the flow path, and an opening 42b1 that communicates with the first opening 41a when the cup 41 is engaged. This simplifies the structure and allows the nutrient solution to be distributed to the plants. Furthermore, the cup 41 is detachable from the pot body 42. Because the cup 41 is detachable from the pot body 42, cleaning the cup 41 is easy. Additionally, the pot body 42 can be removed from the cultivation pot support part 5, making cleaning the pot body 42 easy.

In addition, the volume of the pond 41d of the cup 41 has been increased, for example to 50 cc. This prevents the plant roots from protruding from the pond 41d or coming into contact with the cultivation pot support portion 5. This allows the plant roots to grow sufficiently.

A nutrient solution guide 41c is also provided so that any overflowing nutrient solution falls into the next pond 41d. This allows the overflowing water to fall and be supplied to the lower pond 41d, ensuring an even supply of nutrient solution to each cultivation pot 4. Furthermore, when the cultivation pot 4 is attached to the cultivation pot support 5, the nutrient solution guide 41c is designed to block the second opening 41e and outer surface 41g in a plan view. This ensures that the nutrient solution that drips down the outer surface 41g can be reliably supplied to the lower nutrient solution guide 41c.

In addition, when the cup 41 is attached to the pot body 42, the dowel 41f1 is accommodated in the dowel accommodating portion 42b44, forming a simple locking mechanism. This prevents the cup 41 from coming off the pot body 42.

In addition, guide rails 52 are provided on the cultivation pot support portion 5, and protrusions 42a are provided on the cultivation pot 4 to fit into the guide rails 52. This allows the cultivation pot 4 to be easily attached to the cultivation pot support portion 5. The guide rails 52 are also designed to clamp the protrusions 42a, allowing the cultivation pot support portion 5 to tighten the cultivation pot 4. Friction generated between the guide rails 52 and the protrusions 42a prevents the cultivation pot 4 from moving against its own weight even when a plant is placed in the cultivation pot 4 and the pond 41d is filled with nutrient solution. This structure allows the cultivation pot 4 to be placed at any position on the cultivation pot support portion 5.

In addition, one open side of each cultivation pot support part 5 is located on the opposite side (i.e., the front side) from the side facing the support 2, and the cultivation pots 4 are located on the front side. This makes it easy to install the cultivation pots 4, care for the plants, and harvest them. It also makes it easier for the plants to receive light.

In addition, a nutrient solution distribution unit 3 is provided that can distribute the nutrient solution supplied from a single supply pipe 22 to multiple pipes (eight in this embodiment). This increases the number of plants cultivated per unit area. Furthermore, a pump 61 circulates the nutrient solution between the supply pipe 22 and the cultivation pot support unit 5, allowing for a smaller number of plants to be cultivated. Furthermore, the structure does not require a storage unit above the cultivation pot support unit 5, which increases the stability of the device and simplifies maintenance.

In addition, a rotary drive unit 7 is provided, with the support column 2 serving as the center of rotation axis around which the cultivation pot support unit 5 rotates. This allows airflow to be generated without the need for a separate fan or similar device. Furthermore, because the liquid storage unit 6 does not rotate, the motor 71 consumes less power, allowing for a more compact design.

In this embodiment, the nutrient solution is supplied to the nutrient solution distribution unit 3 using a supply pipe 22 and a relay pipe 23 that pass through the support 2 located in the center of the cultivation device 1. However, the method of supplying the nutrient solution to the nutrient solution distribution unit 3 is not limited to this. For example, a supply pipe may be provided above the nutrient solution distribution unit 3 to supply the nutrient solution to the nutrient solution distribution unit 3. This allows for centralized management of nutrient solution, for example, in a large-scale factory.

In addition, in this embodiment, the cultivation pot support parts 5 are arranged so as to surround the support pole 2. However, this is not limited to this, and the cultivation pot support parts 5 may be arranged in one or more rows. In this case, it is preferable that the nutrient solution distribution part 3 is also structured so that it can direct the nutrient solution to the top of each cultivation pot support part 5 lined up in the row (in accordance with the arrangement of each cultivation pot support part 5).

In this embodiment, the first opening 41a is located on the opposite side of the support 2 (rotation axis) across the cultivation pot support 5. However, this is not limited to this. Alternatively, the open side of the cultivation pot support 5 may face the support 2, with the first opening 41a located on the side opposite the support 2. In this case, it is preferable to locate the light source 10 on the first opening 41a side (i.e., near the support 2). This reduces the number of light sources 10, thereby saving power. Furthermore, when the plants placed in the cultivation pots 4 are small seedlings, the light is concentrated, so energy is not wasted. For this reason, for example, when growing seedlings (the period from sowing seeds to growing seedlings), the open side of the cultivation pot support 5 may be faced toward the support 2, and the seedlings may be grown. After they have grown to a certain extent, the first opening 41a may be located on the opposite side of the support 2 (rotation axis) across the cultivation pot support 5.

Furthermore, in this embodiment, the position of the light source 10 is fixed. However, this is not limiting, and the position of the light source 10 relative to the plant may be changed depending on the growth state of the plant. For example, if the plant is small, the positions of the plant and the light source 10 may be brought closer together, and as the plant grows, the positions of the plant and the light source 10 may be moved further apart.

In this embodiment, the motor 71 is disposed above the nutrient solution distributing unit 3. However, the location of the motor 71 is not particularly limited as long as it can rotate the nutrient solution distributing unit 3 and the cultivation pot supporting unit 5.
By changing the positions of the rotation drive unit 7 and the light source 10 or omitting the light source 10, the frame 8 can be omitted.
<Modification>
Next, a modified example of the cultivation device 1 will be described.
FIG. 14 is a plan view illustrating the arrangement and structure of a modified cultivation pot.

In this modified example, the convex portion 42a does not fit into the guide rail 52. The convex portion 42a is located on the outside of the guide rail 52. Instead, the protrusion 42d is located on the outside of the guide rail 52. When a user grips the cultivation pot 4 and moves it up or down, the protrusion 42d comes into contact with the outer surface 52a of the guide rail 52, preventing the cultivation pot 4 from coming off the cultivation pot support portion 5.

When the protrusion 42d is positioned outside the guide rail 52, the guide rail 52 abuts against the outside of the convex portion 42a (right side in Figure 14), and the cultivation pot support portion 5 clamps the cultivation pot 4. Therefore, although the frictional force is smaller than in the example shown in Figure 11, the friction generated between the guide rail 52 and the outside of the convex portion 42a will cause the cultivation pot 4 to stop against its own weight even when a plant is placed in the cultivation pot 4 and the pond 41d is filled with nutrient solution.

To attach the cultivation pot 4 to the modified cultivation pot support part 5, the cultivation pot 4 is grasped and pressed against the cultivation pot support part 5 from the left side in Figure 14. This causes the protrusion 42d to climb over the guide rail 52 and be positioned on the right side of the outer surface 52a. To remove the cultivation pot 4 from the modified cultivation pot support part 5, the cultivation pot 4 is grasped and pulled toward the left side in Figure 14. This causes the protrusion 42d to climb over the guide rail 52 and be detached from the cultivation pot support part 5.

The arrangement structure when the modified cultivation pot 4 is attached to the cultivation pot support part 5 allows the cultivation pot 4 to be attached to the cultivation pot support part 5 more easily. It also allows the cultivation pot 4 to be removed from the cultivation pot support part 5 more easily.
