As shown in fig. 1A, the hydroponic frame 1 includes a shelf 10, a water bed 20, a plant group 30, a first zone Z1, a second zone Z2 and a third zone Z3, the shelf 10 is used for supporting the water bed 20, and the first, second and third zones Z1, Z2 and Z3 are sequentially connected to each other.

As shown in fig. 1B, the water bed 20 has a first water channel 211, a second water channel 212 and a third water channel 213, and the water bed 20 is used for containing fluid (such as water or nutrient solution); the vegetation group 30 is slidably disposed on the water bed 20 and has a plurality of vegetation units 31 and at least one connecting member C1, wherein the vegetation units 31 can respectively receive vegetation, and the connecting member C1 connects the vegetation units 31. In detail, the graft group 30 can freely slide back and forth among the first, second and third zones Z1, Z2 and Z3 of the water bed 20. In addition to manual movement, a traction mechanism, such as a carrier, a rail, or a combination thereof, may be added to pull the plate assembly 30 to slide between the regions, and detailed features thereof will be described in detail in the following embodiments.

In the present embodiment, any two of the first, second and third zones Z1, Z2 and Z3 do not overlap each other, and the first to third channels 211 to 213 extend through the first, second and third zones Z1, Z2 and Z3. As can also be seen from FIG. 1C, a plurality of plating units 31 are respectively located above the first to third water channels 211 to 213, and the plating unit 31 has a plating hole 311.

It should be noted that the plant is planted in the planting plate unit 31, and the stem of the plant planted in the planting plate unit 31 can extend out of the planting hole 311, and the natural light or artificial light is irradiated above the planting plate unit 31, so that the leaf surface of the plant can receive the light and the plant can grow; the roots of the plants can extend into the water bed 20 from the lower part of the planting plate unit 31, so that the plants can fully absorb water and nutrient solution. The grower can also arrange a retractable packing material (such as foam) in the planting hole 311 according to the actual requirement, and the retractable packing material can be retracted in accordance with the growth of the plant stem, for example, the radial width and/or axial thickness of the planting hole 311 is increased according to various requirements during planting, which is not described herein.

In addition, the surface of each of the first to third water channels 211 to 213 is substantially rectangular or trapezoidal, and an included angle is formed between every two adjacent water channels, so that the first to third water channels 211 to 213 are distributed in a fan shape on the shelf 10 (as shown in fig. 1B); the connecting member C1 is used to connect a plurality of plating units 31, so that when the planter moves the plating group 30, each plating unit 31 connected by the connecting member C1 can move simultaneously.

In the present embodiment, the shelf 10, the water bed 20 and the plant plate assembly 30 may be made of waterproof materials, such as thermoplastic materials, e.g., polypropylene (PP), polyvinyl chloride (PVC) or Polyethylene (PE). Connector C1 has a telescopic tube assembly to allow the planter to adjust the distance of multiple plating units 31 from each other. In other embodiments, the connector C1 may have a spring assembly, a leaf spring assembly, or a pivot assembly.

Referring to fig. 1D and fig. 1E together, fig. 1D is a perspective view of a hydroponic frame 1 according to another embodiment of the present invention, and fig. 1E is a top view of the hydroponic frame 1 in fig. 1D. The main differences between this embodiment and the embodiment of fig. 1A are: the hydroponic frame 1 of the present embodiment further comprises a tractor S, wherein the tractor S has a sliding member S1 and a rail S2. It should be understood that the rail S2 is disposed at one side of the shelf 10, and the sliding member S1 is movably disposed on the rail S2 and connected to the planted plate group 30, the sliding member S1 may have a gear, a slider, etc. inside, so that when the sliding member S1 moves, the planted plate group 30 moves simultaneously due to the connection with the sliding member S1. In addition, the sliding member S1 may also have an automatic device, so that the grower can set the sliding member S1 to move according to the requirement, for example, the sliding member S1 can be set to move at a fixed time, or the automatic device can determine the size of the plant and then move the plant group 30 to a suitable area.

As shown in fig. 1D and 1E, since the first to third waterways 211 to 213 are arranged in a fan shape on the shelf 10, the distance between the plurality of planting holes 311 in the first zone Z1 is smaller than the distance between the plurality of planting holes 311 in the second and third zones Z2 and Z3, i.e. when the planting plate set 30 gradually moves from the first zone Z1 to the second zone Z2 or to the third zone Z3 along the water bed 20 (as shown by the arrow directions in fig. 1D and 1E), the distance between the plurality of planting holes 311 increases, so that the first zone Z1 is suitable for planting the first seedlings with smaller size, and the second and third zones Z2 and Z3 are suitable for the middle seedlings or adult plants with larger size. Of course, the grower can adjust the number of the regions, the length of the regions, the included angle of the water channel, etc. according to the actual planting requirement.

As described above, the planting plate group 30 is slidably disposed on the water bed 20, so that the grower can dispose the planting plate group 30 in the first area Z1 and plant the primary seedlings in the plurality of planting holes 311, respectively, at the initial stage of planting the plants; as the plants grow to a predetermined size, such as a size where the plant leaves contact each other to affect growth of each other, the grower may operate the distractor S to move the planting plate assembly 30 in the direction of the arrows of fig. 1D and 1E, such that the planting plate assembly 30 moves from the first zone Z1 to the second zone Z2.

When the plants in the second zone Z2 grow to be close to the adult plants, the grower can operate the tractor S to move the planting plate group 30 again in the direction of the arrow in fig. 1D and 1E, move the planting plate group 30 in the second zone Z2 to the third zone Z3, and continue planting plants in the third zone Z3 after moving and waiting for harvest. The grower can repeat the above actions to grow plants, so that the planting plate group 30 is moved to an area suitable for the space required by the growth of the plants after the plants grow.

In addition, after the planting plate group 30 originally located in the first zone Z1 is moved to the second zone Z2, the grower can also set another planting plate group 30 and another sliding member S1 on the water bed 20 and the rail S in a slidable manner, respectively, and correspondingly in the vacated first zone Z1, and then plant new primary seedlings therein, i.e. the present invention does not limit the hydroponic frame 1 to have only one planting plate group 30 or only one sliding member S1, and the grower can set a plurality of planting plate groups 30 or a plurality of sliding members S1 on the hydroponic frame 1 according to the actual requirements and simultaneously plant a plurality of groups or a plurality of plants.

Next, please refer to fig. 1F and fig. 1G, wherein fig. 1F is a perspective view of a hydroponic frame module 100 according to another embodiment of the present invention, and fig. 1G is a side view of the hydroponic frame module 100 in fig. 1F. As shown in fig. 1F and 1G, the hydroponic frame module 100 includes a plurality of the above-mentioned hydroponic frames 1, and a plurality of the hydroponic frames 1 are stacked or assembled along a vertical direction (e.g. Z direction in fig. 1F and 1G), wherein each hydroponic frame 1 has a layer of frame 10, a water bed 20, a plant plate group 30, a lighting module 40, a first zone Z1, a second zone Z2 and a third zone Z3 as described above.

In the embodiment, each shelf 10 is used for carrying a water bed 20, the water bed 20 is disposed on the shelf 10 and is used for accommodating water or nutrient solution for plants to absorb, and the plant plate group 30 is slidably disposed on the water bed 20.

third lamps

41, 42 and 43 and the water bed 20 are increased according to the size or type of the plants.

In the present embodiment, each hydroponic frame 1 has a layer frame 10, a water bed 20, a plant group 30 and a lighting module 40, so that each layer of hydroponic frame 1 can be used to plant the same or different plants independently, so that the grower can plant the same or different plants on each layer of hydroponic frame 1, thereby increasing the yield or properly distributing the produced crops. In addition, the illumination of the plant during the initial seedling period is the least, so the first lamp 41 can be set as a point light source (for example, a single chip LED) according to the requirement; when the plant grows to a middle seedling or a mature plant, the requirement for the illumination quantity is more than that in the initial seedling period, so the second and

third lamps

42 and 43 can be arranged as a strip-shaped light source or a surface light source (such as a lamp strip or a lamp panel), and such arrangement can help to save the system construction cost and the operation energy consumption, but the invention does not limit the first lamp 41 to be a point light source, and also does not limit the second and

third lamps

42 and 43 to be a strip-shaped light source or a surface light source, and all the light source configurations can be adjusted according to the actual requirement. In addition, the tractors S may be installed on each hydroponic frame 1, so that the groups of plant plates 30 in each layer can be moved by the traction of the tractors S.

Referring to fig. 2A and 2B, fig. 2A is a perspective view of a hydroponic frame 1 according to another embodiment of the present invention, and fig. 2B is a top view of the hydroponic frame 1 in fig. 2A. As shown in fig. 2A and 2B, the hydroponic frame 1 includes a layer frame 10, a water bed 20, a plant group 30, a first zone Z1, a second zone Z2 and a third zone Z3, the layer frame 10 is used to support the water bed 20, and the first zone, the second zone and the third zone Z1, Z2 and Z3 are sequentially connected to each other.

The water bed 20 is disposed on the shelf 10 and has a first fluid-carrying portion 221, a second fluid-carrying portion 222 and a third fluid-carrying portion 223 connected to each other, the water bed 20 is used for containing fluid (such as water or nutrient solution), the planting plate set 30 is slidably disposed on the water bed 20 and has a plurality of planting plate units 31 and a plurality of connecting members C1, the connecting members C1 are used for connecting the planting plate units 31 to each other, and the planting plate units 31 can be respectively used for containing plants to be planted. In one embodiment, a traction mechanism, such as a carrier, a rail, or a combination thereof, may be added to pull the plate assembly 30 to slide between the regions.

In the present embodiment, the first to third zones Z1 to Z4 do not overlap with each other (as shown in FIG. 2B), and the first to third fluid carrying parts 221 to 223 are respectively located in the corresponding first to third zones Z1 to Z3. In addition, each of the first to third fluid carrying parts 221 to 223 is substantially square, the areas of the first to third fluid carrying parts 221 to 223 are increased progressively, and the plurality of plate-setting units 31 are distributed in a matrix. In one embodiment, each of the first to third fluid carrying portions 221 to 223 may also have a rectangular or trapezoidal shape.

Referring to fig. 2C and fig. 2D together, fig. 2C is an enlarged view of a portion M2 in fig. 2A, and fig. 2D is a schematic view of the plant plate assembly 30 in fig. 2C in an expanded state. As shown in fig. 2C and 2D, a plurality of plate-planting units 31 are disposed above the first fluid bearing portion 221, wherein the plate-planting units 31 have planting holes 311. The plant is planted in the planting plate unit 31, and the plant planted therein, the stem can extend out of the planting plate unit 31 through the planting hole 311, the plant can be illuminated and help to grow by matching with natural light or artificial light above the planting plate unit 31, the plant root can extend into the water bed 20 through the lower part of the planting plate unit 31, so that the plant can fully absorb moisture or nutrient solution, the grower can also configure a telescopic packing material (such as foam cotton) in the planting hole 311 according to the requirement, and the telescopic packing material can be matched with the growth of the plant stem to stretch and widen or thicken the planting hole. In addition, the shelf 10, the water bed 20 and the plate-planting unit 31 may be made of waterproof material, such as thermoplastic material, e.g., polypropylene (PP), polyvinyl chloride (PVC) or Polyethylene (PE).

It should be understood that the connecting member C1 is composed of two pieces (e.g. metal or plastic pieces) pivotally connected to each other, wherein the connecting member C1 can connect a plurality of planting plate units 31 to each other, so that each planting plate unit 31 connected by the connecting member C1 can be moved simultaneously when the planter moves the planting plate assembly 30. The angle between the two sheets in the connecting member C1 can be adjusted by the planter, and when the angle between the two sheets is approximately 0, the planting plate set 30 is in a contracted state (as shown in fig. 2C), and the smaller the angle, the smaller the distance between each planting plate unit 31 is; when the included angle between the two sheets of objects tends to be 180 degrees, the planting plate set 30 is in the unfolded state (as shown in fig. 2D), wherein the distance between each planting plate unit 31 increases, i.e. the larger the included angle is, the larger the distance between two planting holes 311 is, so that the distance between two adjacent planting holes 311 is the largest in the unfolded state.

In addition, the invention does not limit the included angle of the connecting piece C1 to be 0 degree or 180 degrees, when the included angle of the connecting piece C1 is between 0 degree and 180 degrees, the plant plate assembly 30 is in a half-spread state, so that the grower can adjust the included angle of the connecting piece C1 according to the growth condition of the plant, so that the plant plate assembly 30 is adjusted to the condition most suitable for the growth of the plant. Besides manual adjustment of the angle of the connecting member C1, an elastic member (e.g., a spring) can be disposed on the pivot of the connecting member C1 or between the two flaps, so that the connecting member C1 can be unfolded by itself due to the elastic force generated by the elastic member.

Referring to fig. 2E and fig. 2F together, fig. 2E is a perspective view of a hydroponic frame 1 according to another embodiment of the present invention, and fig. 2F is a top view of the hydroponic frame 1 in fig. 2E. The main differences between this embodiment and the embodiment of fig. 2A are: the hydroponic frame 1 in this embodiment has three planting plate groups 30 and a tractor S, wherein the three planting plate groups 30 are slidably disposed on the water bed 20 and located in the first zone Z1, the second zone Z2 and the third zone Z3, respectively, and the tractor S is disposed on the layer frame 10 and connected to the three planting plate groups 30, respectively. It should be understood that the retractor S may have internal mechanical components such as gears, slides, etc. and may retract the graft board assembly 30 in the direction of the arrow in fig. 2E.

As shown in fig. 2E and 2F, since the areas of the first to third fluid bearing parts 221 to 223 are increased progressively, the distance between the planting plate units 31 of the planting plate set 30 can be adjusted by the grower according to the area size of each fluid bearing part, wherein the distance between the adjacent planting holes 311 in the first zone Z1 is smaller than the distance between the adjacent planting holes 311 in the second zone Z2, that is, the distance between the planting holes 311 can be increased after the planting plate set 30 moves from the first zone Z1 to the second zone Z2 or to the third zone Z3 (as shown in the arrow directions of fig. 2E and 2F) on the water bed. As can be seen from fig. 2E and 2F, the plant plate group 30 located in the first zone Z1 is in the contracted state, the plant plate group 30 located in the second zone Z2 is in the half-expanded state, the plant plate group 30 located in the third zone Z3 is in the expanded state, so that the first zone Z1 is better suitable for planting the first seedlings with smaller size, and the second and third zones Z2 and Z3 are better suitable for the middle seedlings or adults with larger size, and so on.

As mentioned above, since the planting plate set 30 is slidably disposed on the water bed 20, when a grower plants a plant at an initial stage, the planting plate set 30 can be disposed on the first fluid bearing portion 221, and the initial seedlings can be planted in the planting holes 311, respectively, and as the plant grows to a middle seedling stage, the plant growing in the planting holes 311 grows to a predetermined size, for example, the plant leaves grow to a size that can contact each other and affect the growth of each other, the grower can operate the tractor S to move the planting plate set 30 along the arrow direction of fig. 2E and 2F, so that the planting plate set 30 moves from the first fluid bearing portion 221 to the second fluid bearing portion 222, and the distance between the planting plate units 31 can be synchronously adjusted to increase the distance between the planting holes 311.

When the plants on the second fluid bearing part 222 grow to another predetermined size again, the grower can operate the tractor S to move the planting plate group 30 on the second fluid bearing part 222 to the third fluid bearing part 223 again along the arrow direction of fig. 2E and 2F, and the grower can repeat the above actions to continue planting the plants and wait for harvesting, or an automatic system can be provided, so that the grower can set the way of moving the planting plate group 30 by the tractor S, for example, to set the planting plate group 30 to move at a predetermined time, or to automatically move the planting plate group 30 to an area suitable for the growth of the plants when the plants grow to a predetermined size, and automatically adjust the distance between the planting plate units 31. The grower can also set more fluid bearing parts or more planting plate groups 30 on the corresponding fluid bearing parts of the hydroponic frame 1 according to the requirement, and can simultaneously plant a plurality of groups of plants with different sizes and/or different types.

Next, please refer to fig. 2G and fig. 2H together, wherein fig. 2G is a perspective view of the hydroponic frame module 100 according to another embodiment of the present invention, and fig. 2H is a side view of the hydroponic frame module 100 in fig. 2G. A grower can stack more than two hydroponic frames 1 to form a hydroponic frame module 100, as shown in fig. 2G and 2H, the hydroponic frame module 100 includes a plurality of hydroponic frames 1, wherein the plurality of hydroponic frames 1 are stacked along a vertical direction (e.g. Z direction in fig. 2G and 2H), each hydroponic frame 1 has a layer of frame 10, a water bed 20, a plant group 30, a lighting module 40, a first zone Z1, a second zone Z2 and a third zone Z3.

In this embodiment, the shelf 10 is used for carrying the water bed 20, the water bed 20 is disposed on the shelf 10, and the planting plate group 30 is slidably disposed on the water bed 20. As shown in fig. 2G and fig. 2H, the lighting module 40 is disposed below the corresponding shelf 10, and has a first lamp 41, a second lamp 42, and a third lamp 43 respectively for providing a light source (e.g., a light supplement lamp) for plant growth.

It should be understood that the lighting module 40 is located above the water bed 20 and the plant group 30, and the first, second and

third lamps

41, 42 and 43 are respectively disposed in the corresponding first, second and third zones Z1, Z2 and Z3 (as shown in fig. 2G); in addition, as further shown in fig. 2H, the first, second and

third lamps

41, 42 and 43 have different heights (as shown in fig. 2H) according to the plant size growing in the first, second and third zones Z1, Z2 and Z3, the first, second and

third lamps

41, 42 and 43 and the water bed 20 therebelow respectively form a first height H1, a second height H2 and a third height H3, the first height H1 is smaller than the second height H2, the second height H2 is smaller than the third height H3, that is, the distances between the first to third lamps 41 to 43 and the water bed 20 are increased.

When a grower plants with the hydroponic frame module 100, the hydroponic frames 1 on each layer of the hydroponic frame module 100 can be planted, and each hydroponic frame 1 is provided with the layer frame 10, the water bed 20, the plant plate group 30 and the lighting module 40, so that the hydroponic frames 1 on each layer can be used for independently planting various plants of the same type but different sizes or different types. In addition, the light quantity of the plant during the initial seedling period is less, so the first lamp 41 can be set as a little light source (for example, a single chip light emitting diode LED), the light quantity of the plant during the growth to the middle seedling or the plant growth is more, so the second to third lamps 42 to 43 can be set as a single light source or a single light source (for example, a light bar or a light plate), and such a setting mode can help to save energy.

Although the present invention has been described with reference to the above embodiments, it is not intended to limit the invention.
