<Cultivation pot>
As described above, a plurality of cultivation pots 4 can be arranged along the longitudinal direction of the cultivation pot support section 5.
FIGS. 5 and 6 are diagrams illustrating the cultivation pot of the embodiment.
The cultivation pot 4 is supported by the 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 part) 41 and a pot body 42. The cup 41 is removably attached to the pot body 42.
FIGS. 7 and 8 are diagrams illustrating the cup of the embodiment.

The cup 41 has a first opening 41a, a plant placement section 41b, a nutrient solution guiding section 41c, a pond 41d, a second opening 41e, and an engaging section 41f. The plant mounting portion 41b and the pond 41d of this embodiment have no boundary and are integrally formed. Some sort of partition may be provided between the plant placement section 41b and the pond 41d.

Plant seedlings are placed on the plant placement section 41b. In addition, when cultivating plants, seeds may be planted in a sponge culture medium (not shown) disposed in the plant mounting portion 41b, and the plants may be cultivated. The medium of the sponge is soaked with the nutrient solution falling from the nutrient solution guide portion 41c, and the nutrient solution is supplied to the plants.

The nutrient solution guide portion 41c is a portion that is held by the user when attaching and detaching the pot body 42 and the cup 41. Further, this nutrient solution guiding section 41c also has the function of a channel for supplying the nutrient solution to the plant mounting section 41b.

The pond 41d is a part for storing the nutrient solution. The nutrient solution overflowing from the pond 41d flows out from the second opening 41e. The volume of the pound 41d is not particularly limited, but is, for example, 50 cc.

The engaging portion 41f includes a spherical dowel 41f1 and a plate-shaped protrusion 41f2 that protrudes from the nutrient solution guiding portion 41c. The engaging portion 41f forms a simple locking mechanism by engaging with a shaped slit (engaged portion) provided in the pot body 42.
9 and 10 are diagrams illustrating the pot body of the embodiment.
The pot main body 42 has a convex portion 42a, a housing portion 42b, a connecting portion 42c, and a protruding portion 42d.

The convex portion 42a is provided along the longitudinal direction of the pot body 42. It fits into a guide rail (described later) of the cultivation pot support section 5. Thereby, the pot main body 42 is supported movably along the longitudinal direction of the cultivation pot support section 5.

The accommodating portion 42b is provided corresponding to the shape of the cup 41, and accommodates the cup 41. The storage part 42b has an opening 42b1 corresponding to the opening 41a of the cup 41, a bottom support part 42b2 that supports the bottom of the cultivation device, and a side support part 42b3 that supports the side of the cultivation device. There is.

Further, the accommodating portion 42b is provided with a slit (engaged portion) 42b4 having a shape corresponding to the engaging portion 41f provided on the cup 41. The slit 42b4 has an insertion part 42b41 through which the dowel 41f1 and the protrusion 41f2 are inserted, a contact part 42b42 which the protrusion 41f2 abuts, and a contact part 42b42 in which the protrusion 41f2 slides toward the contact part 42b42 and approaches the contact part 42b42. It has a stepped portion 42b43 that the dowel 41f1 climbs over, and a dowel accommodating portion 42b44 that accommodates the dowel 41f1 when the protruding portion 41f2 contacts the contact portion. The dowel 41f1 is housed in the dowel accommodating part 42b44 by the protruding part 41f2 coming into contact with the abutting part 42b42 by sliding, forming a simple locking mechanism. Therefore, it is possible to prevent the cup 41 from easily separating from the pot body 42. Further, when the cultivation device 1 is used and the cultivation pot 4 is placed on the cultivation pot support section 5, the slit 42b4 is positioned diagonally. Thereby, it is possible to prevent the cup 41 from easily separating from the pot body 42.

When it is desired to remove the cup 41 from the pot body 42, the dowel 41f1 is removed from the dowel accommodating portion 42b44 by applying a certain amount of force in a direction parallel to the slit. Thereby, the cup 41 can be removed from the pot body 42.
The connecting portion 42c has a shape that can be connected to the upper part of the cultivation pod 4 placed at the lower part of 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 protrusion direction is, for example, 2 mm. The function of the protrusion 42d will be described later.
The explanation will be given by returning to FIG. 6 again.

When the cup 41 is attached to the main body, an opening 44 is formed between the upper part of the nutrient solution guiding part 41c and the pot main body 42. A part of the nutrient solution flowing through the cultivation pot support section 5 flows into the plant mounting section 41b from this opening section 44.
Next, the arrangement of the cultivation pot 4 and the structure of the cultivation pot 4 will be explained.
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 at both ends of the opening surface of the cultivation pot support section 5 along the longitudinal direction. By fitting the convex portion 42a of the pot body 42 into the guide rail 52, the cultivation pot 4 is supported by the cultivation pot support portion 5. Moreover, when the convex part 42a is fitted into the guide rail 52, the guide rail 52 sandwiches the convex part 42a, and the cultivation pot support part 5 has a structure that tightens the cultivation pot 4. Due to the friction generated between the guide rail 52 and the convex portion 42a, even when a plant is placed in the cultivation pot 4 and the pond 41d is filled with the nutrient solution, the cultivation pot 4 stops against its own weight. With the above-described structure, the cultivation pot 4 can be placed at any position on the cultivation pot support section 5.
<Example of usage>
Next, an example of how to use the plant cultivation device 1 will be explained.

A 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. As a fitting method, for example, a method of inserting the convex part 42a into the guide rail 52 from the end of the cultivation pot support part 5, or a method of slightly warping the guide rail 52 of the cultivation pot support part 5 and screwing the convex part 42a Examples include methods.
Next, the user places the plant seedling on the plant placement part 41b of the cup 41.
Next, the user drives the motor 71. As a result, the nutrient solution distribution section 3 and the cultivation pot support section 5 rotate around the support column 2.

Next, the user operates the pump 61. Thereby, the pump 61 pumps up the nutrient solution stored in the liquid storage section 6 and supplies 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 , passes through the relay pipe 23 , and flows into the inlet 31 of the nutrient solution distribution section 3 . As described above, the nutrient solution that has flowed into the inlet 31 passes through each of the eight branch parts 32 and flows out from the outlet 321 of the branch part 32. The nutrient solution flowing out from each outlet 321 passes through the gutter 51 and flows into the cultivation pot support section 5 .
FIG. 12 is a diagram illustrating the flow of the nutrient solution according to the embodiment.
In FIG. 12, an example of the flow of the nutrient solution is shown by dotted arrows.

A part of the nutrient solution that has flowed into the cultivation pot support section 5 is transmitted through the nutrient solution guide section 41c of the uppermost cultivation pot 4 disposed in the cultivation pot support section 5, and is transferred to the plant mounting section 41b and the pond. 41d.

Note that FIG. 12 shows a container 11 that can house plants. The shape of the side portion of the container 11 corresponds to the opening 42b1 of the pot body 42, and the side portion of the container portion 10 engages with the opening 42b1. Thereby, the plant can be stably placed on the plant placement section 41b.
Moreover, a part of the nutrient solution travels along the cultivation pot support part 5 to the cultivation pot 4 located 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 from the second opening 41e, travels along the outer surface 41g of the cup 41, and falls to the lower part.

FIG. 13 is a diagram illustrating the flow of the nutrient solution according to the embodiment. In FIG. 13, in order to make the explanation easier to understand, the reference numeral of the upper cultivation pot is designated as cultivation pot 4a, and the reference numeral of the lower cultivation pot is designated as cultivation pot 4b.

In this embodiment, when the cultivation pots 4a and 4b are attached to the cultivation pot support part 5, the nutrient solution guide part 41c blocks the outer surface 41g in plan view (when viewed from the top of the paper to the bottom of the paper). (See also FIG. 11. In FIG. 11, the positions of the second opening 41e and the outer surface 41g are indicated by dotted lines.) Therefore, a part or most of the nutrient solution that flows out from the second opening 41e of the upper cultivation pot 4a and falls to the lower part along the outer surface 41g hits the nutrient solution guiding part 41c of the lower cultivation pot 4b. , flows into the plant mounting part 41b and the pond 41d through the nutrient solution guiding part 41c of the cultivation pot 4b. A part or most of the nutrient solution flowing out from the second opening 41e of the cultivation pot 4b and falling to the lower part along the outer surface 41g is further guided into the nutrient solution of the cultivation pot 4 located at the lower part (not shown). This corresponds to part 41c. In this way, the nutrient solution is sequentially supplied from the upper cultivation pot 4a toward the lower cultivation pot 4b.

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

As described above, the cultivation device 1 of the embodiment includes the first opening 41a, the plant mounting part 41b on which the plant is placed, and the nutrient solution falling from the flow path of the cultivation pot support part 5. A nutrient solution guide section 41c that guides the nutrient solution to the plant placement section 41b, a pond 41d that stores the fluid flowing in from the nutrient solution guide section 41c, and a second opening 41e that drains the nutrient solution overflowing from the pond 41d into the channel. , and the cup 41 is engaged with a bottom support part 42b2 and a side support part 42b3 in which the cup 41 engages with a convex part 42a attached to the cultivation pot support part 5 forming a flow path. The pot body 42 includes an opening 42b1 that communicates with the first opening 41a when the pot is in the pot. Therefore, the structure can be simplified and the nutrient solution can be distributed to the plants. Moreover, the cup 41 is removable from the pot body 42. Since the cup 41 can be removed from the pot body 42, cleaning of the cup 41 becomes easier. Moreover, since the pot body 42 can also be removed from the cultivation pot support part 5, cleaning of the pot body 42 becomes easy.

Further, the volume of the pound 41d of the cup 41 is increased to, for example, 50 cc. Thereby, it is possible to prevent the roots of the plant from jumping out from the pond 41d or coming into contact with the cultivation pot support section 5 side. Therefore, the roots of plants can be grown sufficiently.

Further, a nutrient solution guide portion 41c is provided so that the overflowing nutrient solution falls into the next pond 41d. As a result, when water overflows, it falls and the nutrient solution is supplied to the lower pond 41d, so that the nutrient solution is evenly supplied to each cultivation pot 4. Moreover, when the cultivation pot 4 is attached to the cultivation pot support part 5, the structure was such that the nutrient solution guide part 41c blocks the second opening part 41e and the outer surface 41g in plan view. Thereby, the nutrient solution that has fallen along the outer surface 41g can be reliably supplied by the lower nutrient solution guide portion 41c.

Further, 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. Thereby, it is possible to prevent the cup 41 from separating from the pot body 42.

Moreover, a guide rail 52 is arranged on the cultivation pot support part 5, and a convex part 42a is provided on the cultivation pot 4 so as to fit into the guide rail 52. Thereby, the cultivation pot 4 can be easily attached to the cultivation pot support part 5. Moreover, the guide rail 52 has a structure in which the convex portion 42a is sandwiched between the cultivation pot support portions 5 and the cultivation pot 4. Due to the friction generated between the guide rail 52 and the convex portion 42a, even when a plant is placed in the cultivation pot 4 and the pond 41d is filled with the nutrient solution, the cultivation pot 4 stops against its own weight. With the above-described structure, the cultivation pot 4 can be placed at any position on the cultivation pot support section 5.

Moreover, one open surface of each cultivation pot support part 5 is arranged on the opposite side (that is, the front side) from the surface facing the support column 2, and the cultivation pot 4 is arranged on the front side. Therefore, it is easy to install the cultivation pot 4, care for plants, harvest, etc. It also allows more light to reach the plants.

Further, a nutrient solution distribution section 3 is arranged which can distribute the nutrient solution supplied from one supply pipe 22 to a plurality of (eight in this embodiment). This increases the number of cultivations per unit area. Moreover, since the nutrient solution is circulated between the supply pipe 22 and the cultivation pot support part 5 by the pump 61, the number of cultivation can be reduced to a small number. Moreover, by adopting a structure in which no storage section is provided above the cultivation pot support section 5, the stability of the device is increased and maintenance is also easy.

Further, a rotational drive section 7 is arranged so that the cultivation pot support section 5 rotates around the support column 2 as the center of rotation axis. This allows airflow to be generated without the need for a separate blower or the like. Furthermore, since the liquid storage section 6 does not rotate, the power consumption of the motor 71 can be suppressed and the motor 71 can be made smaller.

In addition, in this Embodiment, the nutrient solution was supplied to the nutrient solution distribution part 3 using the supply pipe 22 and the relay pipe 23 which pass through the support|pillar 2 arrange|positioned at the center part of the cultivation apparatus 1. However, the method of supplying the nutrient solution to the nutrient solution distribution section 3 is not limited to this. For example, a supply pipe may be provided at the top of the nutrient solution distribution section 3 to supply the nutrient solution to the nutrient solution distribution section 3. . This makes it possible, for example, to centrally manage nutrient solutions in large-scale factories.

Moreover, in this embodiment, the cultivation pot support part 5 is arranged so as to surround the pillar 2. However, the present invention is not limited to this, and the cultivation pot supports 5 may be arranged in one row or in multiple rows. At this time, it is preferable that the nutrient solution distribution section 3 also have a structure (according to the arrangement of the respective cultivation pot supports 5) that can guide the nutrient solution to the upper part of each of the cultivation pot supports 5 arranged in the row direction.

Moreover, in this embodiment, the first opening 41a is arranged on the opposite side of the support 2 (rotation shaft) with the cultivation pot support 5 interposed therebetween. However, the present invention is not limited thereto, and the first opening 41a may be arranged on the side facing the support column 2 with the open surface of the cultivation pot support section 5 facing the support column 2 side. At this time, the light source 10 is preferably placed on the first opening 41a side (that is, near the support column 2). This makes it possible to reduce the number of light sources 10 and save power. Further, when the plant placed in the cultivation pot 4 is a small seedling, etc., the light is concentrated, so there is no wastage of energy. For this reason, for example, when making seedlings (the period of sowing seeds and making seedlings), the open side of the cultivation pot support part 5 is directed toward the support 2 side, and the seedlings are grown. The opening 41a may be arranged on the opposite side of the support 2 (rotation shaft) with the cultivation pot support 5 interposed therebetween.

Furthermore, in this embodiment, the position of the light source 10 is fixed. However, the present invention is not limited to this, and the position of the light source 10 and the plant may be changed depending on the growth state of the plant. For example, if the plant is small, the position of the light source 10 may be moved closer to the plant, and as the plant grows, the position of the light source 10 may be moved further away from the plant.

Further, in this embodiment, the motor 71 is arranged above the nutrient solution distribution section 3. However, the arrangement position of the motor 71 is not particularly limited as long as the nutrient solution distribution section 3 and the cultivation pot support section 5 can be rotated.
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.
<Modified example>
Next, a modification 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 the 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 the user grips the cultivation pot 4 and moves it in the vertical direction, the protrusion 42d hits the outer surface 52a of the guide rail 52, thereby preventing the cultivation pot 4 from separating from the cultivation pot support 5. ing.

When the protrusion 42d is located on the outside of the guide rail 52, the guide rail 52 comes into contact with the outside of the protrusion 42a (on the right side in FIG. 14), and the cultivation pot support part 5 tightens the cultivation pot 4. It becomes. Therefore, although the frictional force is smaller than in the example shown in FIG. 11, the friction generated between the guide rail 52 and the outside of the convex portion 42a causes the plant to be placed in the cultivation pot 4, and the nutrient solution is poured into the pond 41d. Even when filled with water, the cultivation pot 4 stops against its own weight.

The method of attaching the cultivation pot 4 from the cultivation pot support part 5 of the modified example is to grasp the cultivation pot 4 and press it against the cultivation pot support part 5 from the left side in FIG. As a result, the protrusion 42d passes over the guide rail 52 and is located on the right side of the outer surface 52a. A method for removing the cultivation pot 4 from the cultivation pot support part 5 of the modified example is to grasp the cultivation pot 4 and pull the cultivation pot 4 toward the left side in FIG. 14 . Thereby, the protrusion 42d climbs over the guide rail 52 and separates from the cultivation pot support section 5.

According to the arrangement structure when the cultivation pot 4 of the modified example is attached to the cultivation pot support part 5, the cultivation pot 4 can be attached to the cultivation pot support part 5 more easily. Moreover, the cultivation pot 4 can be more easily removed from the cultivation pot support part 5.
