However, it can be readily appreciated that embodiments of the present invention provide many suitable authoring concepts that can be implemented in a wide variety of specific contexts. The particular embodiments disclosed are illustrative only of the use of the invention in a particular way and are not intended to limit the scope of the invention.

Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Referring to fig. 1 and 2, a planting unit P according to an embodiment of the present invention mainly includes a plate 100, a first sidewall 200, a second sidewall 300, and at least one hollow cylinder 400, wherein the first sidewall 200, the second sidewall 300, and the hollow cylinder 400 are connected to the plate 100.

In detail, the board 100 is substantially a rectangular plate-shaped structure and has a first side 110, a second side 120, a third side 130, a fourth side 140, a first surface 150 and a second surface 160. Wherein the first side 110 is opposite to the second side 120, the third side 130 is opposite to the fourth side 140, and the third side 130 and the fourth side 140 are connected to the first side 110 and the second side 120, respectively.

the first sidewall 200 is connected to the first side 110 of the plate body 100, and extends along a Z-axis direction illustrated in the drawing, and protrudes from the first surface 150 of the plate body 100. Similarly, the second sidewall 300 is connected to the second side 120 of the plate body 100 and also extends along the Z-axis direction and protrudes from the first surface 150 of the plate body 100. In addition, since the first side 110 of the plate body 100 is parallel to the second side 120, the first side wall 200 and the second side wall 300 are also parallel to each other.

One or more first recesses 210 are formed in the first sidewall 200, and one or more second recesses 310 are formed in the second sidewall 300. The number of the first recess 210 and the second recess 310 corresponds to the number of the hollow cylinders 400, and the first recess 210 and the second recess 310 are recessed in the Y-axis direction and correspond to each other.

Referring to fig. 1 to 4, the hollow cylinder 400 is disposed between the first sidewall 200 and the second sidewall 300, and a distance between the first sidewall 200 and a center of the hollow cylinder 400 is substantially the same as a distance between the second sidewall 300 and the center of the hollow cylinder 400. One end 410 of the hollow cylinder 400 is connected to the plate 100 and forms a through hole 411 at the connection with the plate 100, and the other end 420 of the hollow cylinder 400 protrudes from the first surface 150 of the plate 100.

In the present embodiment, the first recess 210 and the second recess 310 have the same depth in the Z-axis direction, and the hollow cylinder 400 has a height in the Z-axis direction, and the depth corresponds to the height. For example, the depth of the first and second recesses 210 and 310 may be less than or equal to the height of the hollow cylinder 400.

It should be noted that the distance between the center of the hollow cylinder 400 and the third side 130 of the plate body 100 is the same as the distance between the center of the corresponding first concave portion 210 and/or the second concave portion 310 and the fourth side 140 of the plate body 100. For example, as shown in fig. 4, the distance D1 between the center of the hollow cylinder 400A and the third side 130 is equal to the distance DA between the corresponding first recess 210A and/or second recess 310A and the fourth side 140, and the distance D2 between the center of the hollow cylinder 400B and the third side 130 is equal to the distance DB between the corresponding first recess 210B and/or second recess 310B and the fourth side 140.

In addition, the cross section of the hollow cylinder 400 is axisymmetrical to an axis R, and the first recess 210 and/or the second recess 310 has a shape that is substantially half of the cross section of the hollow cylinder 400. The axis R is parallel to the first side wall 200 and the second side wall 300, and in this embodiment, the axis R may also be substantially perpendicular to the third side 130 and the fourth side 140 of the plate body 100.

For example, in the present embodiment, the cross section of the hollow cylinder 400 is a rectangular cross section which is axisymmetrical to the axis R, and the first recess 210 and the second recess 310 each have a rectangular structure, wherein the length of the rectangular structure in the Y-axis direction is half of the rectangular cross section. As shown in fig. 5A and 5B, in another embodiment of the present invention, the cross section of the hollow cylinder 400 is a circular cross section which is axisymmetrical to the axis R, and the first recess 210 and the second recess 310 each have a semicircular structure.

Referring to fig. 6, the nutrient solution carrier C in an embodiment of the present invention includes a first side 510, a second side 520, a third side 530, a fourth side 540, a bottom 550 and at least one rib 560, wherein the first side 510 is opposite to the second side 520, the third side 530 is opposite to the fourth side 540, and the third side 530 and the fourth side 540 are respectively connected to the first side 510 and the second side 520.

the bottom 550 connects the first side 510, the second side 520, the third side 530 and the fourth side 540, and the first side 510, the second side 520, the third side 530 and the fourth side 540 all extend from the bottom 550 toward the Z-axis direction, so that an accommodating space can be enclosed to accommodate the culture solution.

The rib 560 is disposed on the bottom side 550 and is accommodated in the accommodating space. In the present embodiment, the nutrient solution carrier C may include a plurality of ribs 560, and the ribs 560 may be parallel to each other and parallel to the third side 530 and the fourth side 540. The length of the rib 560 attached to the third side 530 or the fourth side 540 in the Y-axis direction may be substantially equal to the length of the third side 530 or the fourth side 540 in the Y-axis direction, and the length of the rib 560 not attached to the third side 530 or the fourth side 540 in the Y-axis direction should be smaller than the length of the third side 530 or the fourth side 540 in the Y-axis direction, so as to prevent the culture solution from blocking the free flow in the accommodating space in some use situations.

it should be noted that the aforementioned ribs 560 should have the same height as each other in the Z-axis direction, and the height of the ribs 560 in the Z-axis direction is smaller than the height of the third side 530 and the fourth side 540 in the Z-axis direction. In some embodiments, the height of the rib 560 in the Z-axis direction may also be equal to the height of the third side 530 and the fourth side 540 in the Z-axis direction.

As shown in FIG. 6, at least one hole 551 is formed on the bottom side 550 of the nutrient solution carrier C and connected to the bottom side 550 at a suitable position, and the hole 551 can be used as a drainage structure or a liquid level height control structure for the culture solution. In some embodiments, the nutrient carrier C may further comprise a plug (not shown) that detachably closes the hole 551 to retain the culture medium; in addition, when the culture solution in the accommodating space is too much, the user can remove the plug from the hole 551, the culture solution can flow out from the hole 551, and the culture solution can be kept or adjusted in the accommodating space or replaced.

referring to fig. 7A to 7D, a planting system according to an embodiment of the present invention may include a nutrient solution carrier C and at least three identical planting units P (e.g., a first planting unit P ', a second planting unit P ", and a third planting unit P'). The plurality of planting units P are movably disposed on the ribs 560 of the nutrient solution carrier C, and the connection relationship among the planting units P is described below with a first planting unit P ', a second planting unit P ", and a third planting unit P' ″.

When the first planting unit P ', the second planting unit P ", and the third planting unit P'" are assembled with each other and disposed on the nutrient solution carrier C, the second planting unit P "is disposed between the first planting unit P 'and the third planting unit P'", wherein the first surface 150 'of the first planting unit P' and the first surface 150 '"of the third planting unit P'" face the bottom side 550 of the nutrient solution carrier C, and the third side 130 'and the fourth side 140' of the plate body 100 'of the first planting unit P' are respectively adjacent to the third side 530 and the fourth side 540 of the nutrient solution carrier C; and, the third side 130 "'and the fourth side 140"' of the plate body 100 "'of the third planting unit P"' are adjacent to the third side 530 and the fourth side 540 of the nutrient solution carrier C, respectively. The second planting unit P "is then arranged relatively upside down, in a manner that will be described in detail later.

In detail, the second surface 160 "of the second planting unit P" faces the bottom edge 550 of the nutrient solution carrier C, and the third side 130 "and the fourth side 140" of the plate body 100 "of the second planting unit P" are adjacent to the fourth side 540 and the third side 530 of the nutrient solution carrier C, respectively. Thus, the third side 130 'of the first planting unit P' may be aligned with the fourth side 140 "of the second planting unit P", and the fourth side 140 "of the second planting unit P" may be aligned with the third side 130 "'of the third planting unit P"'.

As shown in fig. 7D, the second sidewall 300 'of the first planting unit P' abuts the first surface 150 "of the second planting unit P", and its inner edge is adjacent to the inner edge of the second sidewall 300 "of the second planting unit P". Similarly, the first sidewall 200 "of the second planting unit P" abuts the first surface 150 "'of the third planting unit P'", and the inner edge thereof is adjacent to the inner edge of the first sidewall 200 "'of the third planting unit P'". In this way, when the user moves any one of the first planting unit P ', the second planting unit P ″ and the third planting unit P' ″ relative to the nutrient solution carrier C, the other two planting units can move relative to the nutrient solution carrier C by the mutual contact and linkage of the side walls, which is convenient for operation.

When a user plants using the aforementioned planting system, the seedling may be set in the hollow cylinder 400 (e.g., hollow cylinders 400 ', 400 "') of each planting unit P, and the nutrient solution may be injected into the nutrient solution carrier C. Since the widths of the first and second sidewalls of the plurality of planting units in the X-axis direction are substantially the same as the widths of the first and second sides 510 and 520 of the nutrient solution carrier C in the X-axis direction, when the plurality of planting units P are disposed on the nutrient solution carrier C, the plurality of planting units P are erected on the ribs 560 and can only move back and forth in the Y-axis direction. Further, the hollow cylinder 400 may be spaced apart from the bottom side 550 of the nutrient solution carrier C by the ribs 560, so that the roots of the seedlings have enough space and can grow downward through the hollow cylinder 400 to contact the culture solution in the nutrient solution carrier C.

the space required when the seedling is in the seedling stage is less, and the user can make each planting unit P close to each other to reduce the planting area so as to save the electricity for illumination. As shown in fig. 7A and 7B, since the distance between the center of the hollow cylinder 400 and the third side 130 is the same as the distance between the center of the corresponding first recess 210 and/or the second recess 310 and the fourth side 140, the shape of the first recess 210 and/or the second recess 310 is approximately half of the cross section of the hollow cylinder 400, and the second planting unit P ″ is inverted with respect to the first planting unit P 'and the third planting unit P' ", the structures of the various planting units P ', P", P' "can be matched with each other, so that when the planting units P are tightly close to each other, the hollow cylinder 400" of the second planting unit P "can be partially accommodated in the second recess 310 'of the first planting unit P' and the first recess 210 '" of the third planting unit P' ", and the second side 300 'of the first planting unit P' can be just attached to the first side 200 '" of the third planting unit P' ", so that no gap is generated between the first planting unit P 'and the third planting unit P'.

Similarly, when the planting units P are close to each other, the hollow cylinders 400 ', 400 "' of the first and third planting units P 'and P"' may also be respectively and exactly partially accommodated in the second and first recesses 310 "and 210" of the second planting unit P ". Therefore, the seedlings in the hollow cylinders 400 ', 400 "' of the first planting unit P 'and the third planting unit P'" can still contact the culture solution in the nutrient solution carrier C and can not be blocked by the plate body 100 "of the second planting unit P" due to the close proximity of the seedlings.

By the structure and the operation, the planting density of the seedling plants on the planting system can be reduced or increased, and light only needs to be provided in the area (such as the area M) with the seedling plants, so that the whole area of the nutrient solution carrier C does not need to be irradiated as in the prior art, and the problems of energy consumption and uneven irradiation are reduced.

As shown in fig. 7C and 7D, when the growth height and volume of the seedling plant are increased, the user can move at least one of the planting units P along the Y-axis direction relative to the nutrient solution carrier C, and the other planting units P can also be indirectly driven by the mutual sidewall connection to move along the Y-axis direction relative to the nutrient solution carrier C. Thus, the space between the hollow columns 400 of each planting unit P can be increased, and the growth space of the seedling is increased. In this embodiment, the hollow cylinders 400 ', 400 "' of the first planting unit P 'and the third planting unit P"' are spread apart from each other by a greater distance after operation. In detail, when the plurality of planting units P are stretched to be disposed farthest from each other, the inner edge of the second sidewall 300 ' of the first planting unit P ' is attached to the inner edge of the second sidewall 300 ″ of the second planting unit P ″ and the inner edge of the first sidewall 200 ″ of the second planting unit P ″ is attached to the inner edge of the first sidewall 200' of the third planting unit P ″.

Referring to fig. 8A to 8C, in another embodiment of the present invention, the planting system may further include a frame body F on which the nutrient solution carrier C and the planting unit P may be disposed. The frame body F may further include a conveying module 600, an illumination module 700, and a push rod 800.

the transport module 600 may be, for example, a track set or a roller set, and the nutrient carriers C and the planting units P may be disposed on the transport module 600 and between the transport module 600 and the lighting module 700. The lighting module 700 may have at least two lighting regions 710, 720, wherein the size of the lighting region 710 corresponds to region M and the size of the lighting region 720 corresponds to region N (fig. 7C). As shown, the area M can at least illuminate the planting area when the plurality of planting units P are most closely condensed with each other, and the area N can illuminate the planting area when the plurality of planting units P are most widely spread with each other, wherein the area N at least covers the area of the nutrient solution carrier C.

In some embodiments of the present invention, the frame body F is applicable to the production line concept, that is, a plurality of liquid carriers C can be arranged on the conveying module 600, and each liquid carrier C can carry one or more planting units P. The height of each part of the lighting module 700 may be different corresponding to different nutrient solution carriers C, so as to adapt to the growth state of the seedling with different width and height in different growth cycles. For example, the illumination area 710 of the illumination module 700 may be closer to the nutrient solution carrier C corresponding to a lower height seedling, and the illumination area 720 may be farther from the nutrient solution carrier C corresponding to a higher height seedling. The nutrient solution carrier C is moved to the illumination modules 700 with different erection heights through the conveying module 600 for illumination, and the space among the plurality of planting units P can be expanded according to the requirement, so that the requirement of greatly adjusting equipment or setting of the production line can be reduced, and the convenience of planting is improved.

when the seedling plant is at the seedling stage, the planting units P on the nutrient carrier C may be in the close proximity state illustrated in fig. 7A and 7B, and the nutrient carrier C and the planting units P may be located at a first position corresponding to the illumination area 710 (fig. 8A). At this time, the illumination area 710 of the illumination module 700 may provide light to illuminate the area M, and the illumination area 720 may be turned off to reduce energy consumption.

As shown in fig. 8B, after the seedling grows, the user can manually operate the push rod 800 or move one or more planting units P on the nutrient solution carrier C relative to the nutrient solution carrier C by using the machine moving push rod 800, so that the planting units P can be in the unfolded state shown in fig. 7C and 7D. It should be noted that, in the present embodiment, the planting unit P closest to the second side edge 520 may have a side bar 161 protruding from the second surface 160 of the board 100. The push rod 800 can contact the edge bar 161 to move the planting unit P. In addition, the side strips 161 can prevent the branches and leaves from extending out of the frame body F when the seedlings grow, so that the seedlings are not damaged because workers do not touch the branches and leaves when moving between production lines. In some embodiments, the planting unit P closest to the first side 510 may also have such a side strip extending toward the Z-axis direction, which is not limited by the present invention.

As shown in fig. 8C, in another embodiment of the present invention, the edge 161 can be inclined with respect to the first side 510, and the pushing rod 800 is also inclined with respect to the first side 510 corresponding to the edge 161. In this way, when the conveying module 600 drives the liquid-feeding carrier C to move, the side bar 161 will slide along the push rod 800, and one or more planting units P on the liquid-feeding carrier C can move relative to the liquid-feeding carrier C, so that the planting units P are in the unfolded state shown in fig. 7C and 7D.

as shown in fig. 8D, after the one or more planting units P are moved by the pushing rod 800 to assume the unfolded states shown in fig. 7C and 7D, the delivering module 600 can also move the nutrient solution carrier C and the planting units P from the first position to a second position, wherein the second position corresponds to the illumination area 720 of the illumination module 700. At this time, the illumination area 720 of the illumination module 700 may provide light to the nutrient solution carrier C to illuminate the seedlings on the planting units P. Meanwhile, the illumination area 710 can be turned off to reduce energy consumption.
