[0028] Figure 1 shows an exploded perspective view of a cultivation device 1 according to one embodiment of the present invention.

[0029] Referring to Figure 1, a cultivation apparatus 1 according to one embodiment of the present invention may include a cultivation plate 10 and a cultivation chamber 20.

[0030] Plants can be planted on the cultivation plate 10. The cultivation plate 10 can be configured to accommodate multiple plants. The cultivation plate 10 can include cultivation holes 11 into which plants can be planted. Multiple cultivation holes 11 can be formed on the cultivation plate 10. The cultivation holes 11 can be formed, for example, in the shape of a square opening. The cultivation holes 11 can be formed at predetermined intervals on the cultivation plate 10. The cultivation holes 11 may also be formed at equal intervals on the cultivation plate. The cultivation holes 11 can be arranged at intervals in a grid pattern, for example, as shown in Figure 1, in which case one cultivation hole 11 and adjacent cultivation holes 11 can be placed alternately to form a row in the diagonal direction. However, the arrangement of the cultivation holes 11 can be varied as needed, and the size of the cultivation holes 11 and the spacing between them can be varied accordingly. Furthermore, the cultivation plate 10 can be formed in a square or rectangular shape, for example, but is not limited thereto.

[0031] The cultivation chamber 20 can be provided so that the cultivation plate 10 is placed on it. The cultivation chamber 20 can have a cultivation opening 21 in which the cultivation plate 10 is positioned. The cultivation plate 10 can be placed in the cultivation chamber 20 and cover the cultivation opening 21 of the cultivation chamber 20. The internal space of the cultivation chamber 20 can contain a nutrient solution that can be supplied to the plants planted on the cultivation plate 10. The nutrient solution can be contained inside the cultivation chamber 20 at a predetermined water level from the bottom surface of the cultivation chamber 20. The cultivation chamber 20 can be formed in a shape that extends longitudinally with a predetermined width.

[0032] The cultivation chamber 20 may include a support frame 30. The support frame 30 may be formed inside the cultivation chamber 20. The support frame 30 may be formed in the shape of a plate extending across the internal space of the cultivation chamber 20. The support frame 30 may support the cultivation plate 10 placed in the cultivation chamber 20 from the inside. The support frame 30 may contact the bottom surface of the cultivation plate 10 placed in the cultivation chamber 20 to support the load of the cultivation plate 10. The support frame 30 may contact the central part of the cultivation plate 10 to support the central part of the cultivation plate 10. The support frame 30 may be formed to protrude from the inner surface of the cultivation chamber 20.

[0033] A cultivation device 1 according to one embodiment of the present invention may include a first service groove 51 and a second service groove 52. By adopting the configuration of the first service groove 51 and the second service groove 52, when the cultivation plate 10 is placed in the cultivation chamber 20, a service opening can be formed in the cultivation device 1 according to one embodiment of the present invention, allowing external equipment to access it.

[0034] The first service groove 51 can be formed in the cultivation plate 10. The first service groove 51 can be formed by recessing from the edge of the cultivation plate 10. Multiple first service grooves 51 can be formed on the cultivation plate 10. When the cultivation plate 10 is placed in the cultivation chamber 20, the first service groove 51 can form part of the service opening described later.

[0035] The second service groove 52 can be formed in the cultivation chamber 20. The second service groove 52 can be formed by recessing from the upper end of the cultivation chamber 20 where the cultivation opening 21 is formed. When the cultivation plate 10 is placed in the cultivation chamber 20, the second service groove 52 can form a service opening together with the first service groove 51 of the cultivation plate 10.

[0036] The second service groove 52 can be formed in a position corresponding to the first service groove 51 formed on the cultivation plate 10 when the cultivation plate 10 is placed in the cultivation chamber 20.

[0037] Multiple first service grooves 51 and corresponding second service grooves 52 can be formed, for example, at the longitudinal ends of the cultivation plate 10 and the cultivation chamber 20. In this case, an external device (e.g., a robotic arm) can be inserted longitudinally into the cultivation plate 10 and the cultivation chamber 20 to approach the interior of the cultivation chamber. If necessary, the first service grooves 51 and the second service grooves 52 can be formed at the lateral ends of the cultivation plate 10 and the cultivation chamber 20 perpendicular to the longitudinal direction. In this case, the direction from which the external device approaches can be from the lateral direction of the cultivation plate 10 and the cultivation chamber 20, corresponding to the positions in which the first service grooves 51 and the second service grooves 52 are formed. When the first service grooves 51 and the second service grooves 52 are formed at both lateral ends of the cultivation plate 10 and the cultivation chamber 20, the external device can approach the cultivation plate and the cultivation chamber by clamping both sides. In contrast, if the first service groove 51 and the second service groove 52 are formed only at one end of the cultivation plate 10 and the cultivation chamber 20, an external device can approach the cultivation plate 10 and the cultivation chamber 20 from one direction to lift the cultivation plate or perform a preset operation inside the cultivation chamber 20, and it goes without saying that the location where the first service groove 51 and the second service groove 52 are formed is not limited to the examples described above.

[0038] Figure 2 shows a coupled perspective view of a cultivation apparatus 1 according to one embodiment of the present invention. Referring to Figure 2, the cultivation plate 10 can be placed on the cultivation chamber 20. When placed on the cultivation chamber 20, the cultivation plate 10 can cover at least a portion of the cultivation opening 21 of the cultivation chamber 20. That is, the cultivation plate 10 is formed to a size corresponding to the cultivation opening 21 of the cultivation chamber 20 and is provided to cover the entire cultivation opening 21, or it is formed to be smaller than the size of the cultivation opening 21 and can cover a portion of the cultivation opening 21. If the cultivation plate 10 covers only a portion of the cultivation chamber 20, the cultivation plate 10 can move (e.g., slide) in the longitudinal direction of the cultivation chamber 20 without detaching from its alignment with the cultivation chamber 20. The cultivation plate 10 can interlock and be coupled to the cultivation chamber 20. The cultivation plate 10 can be positioned on the cultivation opening 21 of the cultivation chamber 20.

[0039] The support frame 30 of the cultivation chamber 20 can contact the bottom surface of the cultivation plate 10 and support the load of the cultivation plate 10 from the inside. The support frame 30 can also contact the central part of the cultivation plate 10 and support the cultivation plate 10. By adopting this configuration, even when an external load is applied to the cultivation plate 10, damage to the cultivation plate 10 can be greatly reduced, and the durability of the cultivation plate 10 in withstanding the load of plants planted in the cultivation hole 11 can be greatly improved.

[0040] When the cultivation plate 10 is placed in the cultivation chamber 20, a service opening 50 can be formed in the cultivation apparatus 1 according to one embodiment.

[0041] The service opening 50 allows communication between the internal space of the cultivation chamber 20 and the outside. External mechanical devices (e.g., a robotic arm) can approach the inside of the cultivation chamber 20 through the service opening 50, thereby greatly improving the efficiency of plant cultivation.

[0042] The service opening 50 can be formed by a first service groove 51 formed in the cultivation plate 10 and a second service groove 52 formed in the cultivation chamber 20. The first service groove 51 and the second service groove 52 can each form a part of the service opening 50. For example, the first service groove 51 and the second service groove 52 can be formed with the same width. The first service groove 51 and the second service groove 52 can be connected to each other when the cultivation plate 10 is placed in the cultivation chamber 20.
