Description

Technical Field

[0001] This invention belongs to the technical field of plant cultivation devices, specifically, it relates to a three-dimensional planting device. Background Technology

[0002] Vertical farming, also known as three-dimensional planting, is a cultivation model that typically involves planting in layers according to a vertical gradient using methods such as trellises or hanging structures. This fully utilizes vertical space and sunlight, improving land utilization. This planting method can develop and utilize many non-arable lands (such as indoor spaces and building exteriors), expanding and supplementing non-renewable arable land resources. At the same time, it can achieve high-yield, high-efficiency, and environmentally friendly planting results, thus attracting increasing attention.

[0003] Currently, common vertical planting methods include wall planting and hanging planting, which mostly utilize a tiered structure to stack cultivation containers vertically to make full use of vertical space. However, existing vertical planting devices have the following technical problems: plants in the upper cultivation containers can easily block the plants in the lower cultivation containers, resulting in insufficient light for the plants in the lower cultivation containers and affecting their growth; vertical planting devices can only use a limited variety of planting substrates, most of which can only be hydroponically grown, and there are few suitable plant varieties; at the same time, vertical planting devices are inconvenient to clean, complex to install, and occupy a lot of space, making them inconvenient for storage and transportation.

[0004] In view of this, it is necessary to further improve the existing vertical planting equipment. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the plants in the lower planting container of traditional three-dimensional planting devices have insufficient light, the varieties of plants that can be planted are relatively limited, the planting device is inconvenient to clean and install, and occupies a lot of space.

The limiting protrusions on the first inner wall are offset from the limiting protrusions on the second inner wall. The limiting protrusions can be adapted to be inserted into the limiting groove, or the limiting protrusions are offset from the limiting groove.

[0020] Preferably, a stacking limiting rib is also provided in the connecting groove, and the stacking limiting rib is located at the top of the connecting groove.

[0026] Preferably, the substrate storage mechanism has a water absorption hole on its bottom surface, and the bottom of the substrate storage mechanism is also connected to a support leg, the bottom end of which abuts against the bottom wall of the container.

[0027] The technical solution of the present invention has the following advantages compared with the prior art:

[0028] (1) The three-dimensional planting device provided by the present invention includes: at least two stacked planting troughs, the sidewalls of which are inclined outward relative to their bottom walls, a planting cover plate detachably connected to the top of the planting trough, a connecting boss inside the planting trough, the connecting boss having a connecting groove communicating with the outside, a substrate storage mechanism detachably connected inside the planting trough, and a liquid guiding mechanism connected to the top of the connecting boss of the top planting trough. In this three-dimensional planting device, the sidewalls of the planting troughs are inclined outward relative to their bottom walls, and an inclined angle for light irradiation can be formed between the upper and lower planting troughs, so that the plants in the lower planting trough can receive sufficient light, thus improving the light utilization rate. By setting a substrate storage mechanism inside the planting trough, connecting a planting cover plate to the top of the planting trough, and connecting a liquid guiding mechanism to the top of the connecting boss of the top planting trough, a flowing liquid circulation path is formed. The planting device can be used for hydroponics through the planting cover plate or for substrate cultivation through the substrate storage mechanism, thus being compatible with both hydroponics and substrate cultivation methods. This device can connect at least two planting troughs by connecting grooves and connecting bosses. This connection method is simple to install, and the connected three-dimensional planting device occupies little space, saving space and packaging materials. At the same time, the detachable planting cover makes it easy to clean the inside of the planting trough.

[0029] (2) The three-dimensional planting device provided by the present invention also has a drainage slot structure at the bottom of the planting trough. When in use, the water level pipe can be inserted into the limiting baffle through the insertion slot. The insertion slot serves to avoid the limiting baffle. At this time, the bottom end of the water level pipe abuts against the bottom of the drainage slot, and the water inlet is completely blocked. The water level can only flow downward when it rises to the top of the water level pipe, thus meeting the requirements of water volume and water level for hydroponic planting mode; or the end of the water level pipe without the insertion slot is sleeved on the outside of the first baffle. At this time, the end of the water level pipe abuts against the limiting protrusion, and the water inlet is not blocked. The water can flow to the next layer of planting trough, which can meet the tidal irrigation requirements of substrate cultivation and further realize the effect of enriching planting mode.

[0030] (3) The three-dimensional planting device provided by the present invention includes a liquid guiding mechanism comprising a liquid guiding box sleeved on the connecting boss and a liquid guiding box cover plate detachably connected to the liquid guiding box. By sleeved on the outside of the connecting boss, the liquid guiding box plays the role of guiding nutrient solution, and the liquid storage cover plate can provide the function of blocking light and preventing direct light from shining on the nutrient solution in the liquid guiding box.

[0031] (4) The three-dimensional planting device provided by the present invention includes a first planting cover plate and a second planting cover plate that are adapted to snap together. A substrate storage mechanism is also detachably connected inside. The snap-fit ​​first and second planting cover plates are easy to install and remove without the need for tools. During substrate cultivation, the substrate storage mechanism can be directly installed in the planting trough. The above structure makes the planting device easy to install and remove, and also convenient to clean. After removing the planting cover plate and the substrate storage mechanism, the planting trough can be thoroughly rinsed without any dead angles.

[0032] (5) The three-dimensional planting device provided by the present invention has the same structure for the first planting cover plate and the second planting cover plate, both including a cover plate body. One end of the cover plate body is provided with a male plug-in buckle, and the other end is provided with a female plug-in buckle. The first planting cover plate and the second planting cover plate are connected by the male plug-in buckle and the female plug-in buckle. This arrangement allows the first planting cover plate and the second planting cover plate to be installed by symmetrically plugging them in. The plug-in structure is simple and convenient, and the production cost of the planting cover plate is lower, as there is no need to make two different molds. Attached Figure Description

[0054] Example

[0055] This embodiment provides a three-dimensional planting device. Please refer to [link / reference]. Figures 1-16The system comprises at least two planting troughs 1, which are stacked vertically to form a planting structure that fully utilizes longitudinal space and is suitable for three-dimensional plant cultivation. Specifically, each planting trough 1 has the same structure, with an open end 101 at the top, allowing it to function as an open container for easy stacking, cleaning, and crop cultivation. A bottom wall 102 is located on the side opposite the open end 101 (i.e., the bottom of the planting trough 1), and a side wall 103 is provided between the open end 101 and the bottom wall 102. As shown in the figure, in this embodiment, the planting trough 1 has a structure that is wider at the top and narrower at the bottom. The side wall 103 is inclined outward relative to the bottom wall 102, and in this embodiment, the open end 101 is a smooth, rounded rectangle.

[0056] The open end 101 of the planting trough 1 is detachably connected to a planting cover 2. A connecting boss 3 is provided inside the planting trough 1, connected to the bottom wall 102 of the planting trough. A connecting groove 301 is formed inside the boss 3, penetrating the bottom wall 102 and communicating with the outside. As shown in the figure, the connecting boss 3 has a trapezoidal structure, narrow at the top and wide at the bottom. When at least two planting troughs 1 are stacked, the connecting boss 3 in the lower planting trough 1 can be fitted into the connecting groove 301 of the connecting boss 3 in the upper planting trough 1, forming a vertically stacked structure. A liquid guiding mechanism 4 is also connected to the top of the connecting boss 3 in the topmost planting trough 1. A substrate storage mechanism 13 can also be detachably connected inside the planting trough 1. Substrate can be filled into the substrate storage mechanism 13, and plants can be planted in the substrate for substrate cultivation.

[0057] The three-dimensional planting device provided in this embodiment includes at least two planting troughs 1 stacked vertically. Each planting trough 1 has a water storage space and an open top, forming a wide-top, narrow-bottom open container structure. The side walls of the planting trough 1 are inclined outwards relative to the bottom wall. This creates an inclined angle between the upper and lower planting troughs 1, allowing light to reach the plants in the lower planting trough 1, thus ensuring sufficient light for their growth. This promotes plant growth in all layers of planting troughs 1 and improves light utilization. The light can come from sunlight or from plant supplemental lighting. A liquid guiding mechanism 4 is connected to the top of the connecting boss 3 on the top planting trough 1, which guides the flow of nutrient solution or water. By detachably connecting the substrate storage mechanism 13 within the planting trough 1, connecting the planting cover plate 2 to the top of the planting trough, and setting a liquid guiding mechanism 4 above the top planting trough 1, a circulation path for liquid flow is formed. The planting device can grow plants hydroponically within the planting cover plate 2 or via substrate cultivation through the substrate storage mechanism 13, making the device compatible with both hydroponic and substrate cultivation modes. Simultaneously, by providing connecting bosses 3 within the planting trough 1 and connecting grooves 301 within the connecting bosses 3, at least two planting troughs in the planting device can be fitted together via the matching connecting bosses 3 and connecting grooves 301 to form a stacked structure. This connection method is simple to install, provides stable stacking, and occupies little space after stacking, improving space utilization, reducing packaging material usage, and facilitating storage and transportation. The detachably connected planting cover plate 2 makes cleaning the planting trough 1 convenient.

[0058] Please see Figure 4-8 In this embodiment of the three-dimensional planting device, the bottom wall 102 of the planting trough is also provided with a drainage slot. The drainage slot is formed by a first baffle 5 and a second baffle 6 arranged at intervals. In this embodiment, preferably, the cross-sectional shape of the first baffle 5 and the second baffle 6 is circular, so that the drainage slot is an annular groove structure with an open top. The first baffle 5 is formed by at least two spaced limiting baffle parts 501. The interval between the at least two limiting baffle parts 501 forms a water inlet 502 for water supply or nutrient solution flow. A limiting protrusion 7 is also provided in the drainage slot. A water level pipe 8 is detachably connected to the first baffle 5. One end of the water level pipe 8 is provided with a plug groove 801. The bottom wall 102 of the planting trough is also provided with a drainage through hole 9, which is opened on the inner periphery of the first baffle 5.

[0059] In use, the connection method between the water level pipe 8 and the first baffle 5 can be selected according to needs to achieve the function of regulating drainage and meeting different planting needs. Specifically, in the hydroponic planting mode with a large water requirement, the water level pipe 8 can be adapted to be inserted into the limiting baffle 501 through the insertion groove 801 (e.g., Figure 8As shown), the insertion groove 801 forms a clearance space. The depth of the insertion groove 801 is adapted to the height of the limiting baffle 501, so that the end face of the water level pipe 8 can abut the bottom of the drainage slot. The side wall of the water level pipe 8 completely blocks the water inlet 502, thus closing the water inlet 502. At this time, overflow will only occur when the water level rises to the top of the water level pipe 8, which meets the requirements of water volume and water level for hydroponic planting mode. In substrate cultivation mode, the end of the water level pipe 8 without the insertion groove 801 can be sleeved on the outside of the first baffle 5 (e.g., Figure 7 As shown in the diagram, at this time, the bottom end of the water level pipe 8 abuts against the limiting protrusion 7, and the water level pipe 8 fails to block the water inlet 502. Water can flow through the water inlet 502 and the drainage hole 9 to the planting trough 1 of the next layer. The water in the planting trough 1 of this layer can be slowly and automatically drained, which can meet the tidal irrigation needs of substrate cultivation. Thus, the three-dimensional planting device provided in this embodiment can meet both hydroponics and substrate cultivation modes, enriching the types of plants that can be planted. With the above-mentioned drainage structure, there is no need to set up a large-sized water tank or use an electric device such as a continuously operating water pump or solenoid valve, further realizing the technical effect of small size, simple structure, low cost and higher reliability of the planting device.

[0060] In the drainage slot structure, a set of baffle limiting ribs 10 are also protruding from the inner side of the second baffle 6. When the water level pipe 8 is connected to the first baffle 5, the baffle limiting ribs 10 play a role in securing the water level pipe 8 to make it more stable. In this embodiment, the baffle limiting ribs 10 are evenly distributed on the inner circumference of the second baffle 6 and are set at the positions corresponding to the limiting baffle part 501 and the water inlet 502. The limiting protrusion 7 is set between the baffle limiting rib 10 and the baffle limiting part 501. As shown in the figure, in this embodiment, the limiting baffle part 501 is four arc-shaped baffles arranged at intervals, forming four water inlets 502 at the intervals. The four limiting protrusions are correspondingly set between the four limiting baffle parts 501 and the baffle limiting ribs 10.

[0061] The number of insertion slots 801 corresponds to the number of limiting baffles 501, allowing the water level pipe 8 to be properly inserted into the limiting baffle 501 through the insertion slots 801, ensuring a good fit and fully sealing the water inlet 502. The end of the water level pipe 8 without the insertion slots 801 has a flat end face, which can abut against the top of the limiting protrusion 7, leaving the water inlet 502 unsealed. In this state, the water flow at the water inlet 502 is less than the water supply flow of the water pump. Thus, when the water pump supplies water, the water level can quickly rise to the top of the water level pipe 8 and flow to the next planting trough. After the water pump stops, the water in the planting trough can be slowly and automatically drained through the water inlet 502, meeting the needs of intermittent irrigation (tidal irrigation) in substrate cultivation.

[0062] To facilitate drainage, the bottom of the drainage slot is lower than the inner surface of the bottom wall 102 of the planting trough, meaning that the drainage slot is a recessed groove set in the bottom wall 102 of the planting trough.

[0063] Furthermore, in order to balance the planting area and light utilization rate during the vertical planting process, and to ensure that the plants in the lower planting trough 1 receive sufficient light, the inclination angle between the side wall 103 and the bottom wall 102 of the planting trough is 20-80°. In this embodiment, 40° or 50° is preferred, and the above inclination angle can be set according to actual planting needs. Figure 11 As shown, in the above-mentioned inclined structure, in the two stacked planting troughs 1, the side wall of the upper planting trough 1 and the open end 101 of the lower planting trough 1 form an inclined angle B. At the same time, there is a gap A between the open ends 101 of the upper and lower planting troughs 1. In this way, the plants planted in the upper planting trough 1 will not block the plants and light in the lower planting trough 1, and the plants in the lower planting trough 1 will have sufficient growing space.

[0064] To further meet the light and height requirements of the plants in the lower planting trough 1, and to minimize the space occupied by the vertical planting device when not in use, the at least two stacked planting troughs 1 have two connection methods, which are achieved through the following structure: Figure 9-12 As shown, the connecting boss 3 has a trapezoidal structure that is narrower at the top and wider at the bottom with smooth corners. This makes the bottom dimension of the connecting groove 301 larger than the top dimension of the connecting boss 3. Thus, when planting troughs 1 are stacked, the connecting boss 3 in the lower planting trough 1 can be inserted into the connecting groove 301 of the connecting boss 3 in the upper planting trough 1. A limiting groove 302 is provided on the side wall of the connecting boss 3, and a limiting protrusion 303 is provided in the connecting groove 301 at the position corresponding to the limiting groove 302. When the three-dimensional device is not in the planting state and needs to be stacked for storage and transportation, multiple planting troughs 1 can be stacked and connected. The upper limiting protrusion 303 can be fitted into the lower limiting groove 302, making the upper and lower layers of planting troughs 1 tightly connected, reducing the space occupied by the three-dimensional planting device, saving packaging materials, and reducing storage and transportation costs. In this embodiment, to ensure smooth insertion of the limiting protrusion 303 and the limiting groove 302, both adopt a trapezoidal cross-sectional structure.

[0065] As an alternative implementation, the following approach can also be adopted: a limiting protrusion is provided on the side wall of the connecting protrusion 3, and a corresponding limiting groove is provided in the connecting groove 301, as long as the tight insertion and stacking effect of the two adjacent planting grooves can be achieved.

[0066] like Figure 9-10 As shown, in this embodiment, the connecting boss 3 includes a first sidewall 304 and a second sidewall 305 disposed opposite to each other. The first sidewall 304 is provided with at least two limiting grooves 302, and the second sidewall 305 is also provided with at least two limiting grooves 302. The limiting grooves 302 located on the first sidewall 304 and the limiting grooves 302 located on the second sidewall 305 are misaligned.

[0067] like Figure 12 As shown, the connecting groove 301 has a first inner wall 3011 and a second inner wall 3012 arranged opposite to each other. The first inner wall 3011 and the second inner wall 3012 are respectively provided with at least two limiting protrusions 303. In the above-mentioned tightly stacked state, the limiting protrusions 303 on the first inner wall 3011 and the limiting protrusions 303 on the second inner wall 3012 are respectively adapted to be inserted into the limiting grooves 302, so that the two adjacent planting troughs 1 are tightly stacked and connected, saving space. In the planting state, it is necessary to provide height space for plant growth. At this time, the two adjacent planting troughs 1 are rotated 180° relative to each other. In this state, the limiting protrusions 303 and the limiting grooves 302 are misaligned. The limiting protrusions 303 cannot be inserted into the limiting grooves 302. Instead, the limiting protrusions 303 of the upper connecting boss abut against the top surface of the lower connecting boss 3. In this way, the distance between the open ends of the upper and lower planting troughs is large, reserving sufficient space for plant growth and light.

[0068] To ensure a stable connection between the multi-layer planting troughs during planting, as shown in the figure, the length of the limiting protrusion 303 is less than the depth of the connecting groove 301. A protrusion limiting rib 11 is also provided at the end of the limiting protrusion 303 away from the top of the connecting groove 301. During planting, the protrusion limiting rib 11 in the upper connecting boss 3 is engaged with the top of the lower connecting boss 3, eliminating the swaying space, preventing the upper and lower planting troughs 1 from swaying relative to each other, and improving the stability of the device.

[0069] To prevent the planting troughs 1 from being difficult to separate when they are tightly stacked, a stacking limiting rib 12 is also provided in the connecting groove 301. The stacking limiting rib 12 is located at the top of the connecting groove 301. When the planting troughs 1 are tightly stacked, the stacking limiting rib 12 provides the insertion endpoint, preventing the problem of two adjacent planting troughs 1 being too tightly inserted and difficult to separate during use, thus improving the efficiency of use.

[0070] To ensure sufficient vertical spacing between adjacent planting troughs 1 in the planting state, one end of the connecting boss 3 is connected to the bottom wall 102 of the planting trough, and the other end extends above the open end 101, that is, the connecting boss 3 is higher than the side wall 103 of the planting trough.

[0071] To further enhance the installation stability of the planting device, the connecting boss 3 is also provided with column connection holes 306. The stacked planting troughs 1 can be connected into one unit through the columns passing through the column connection holes 306, further improving stability. A water pipe connection hole 307 is also provided in the center of the connecting boss 3 for the passage of water pipes.

[0072] like Figure 2-3 , Figure 13As shown, in this embodiment, the liquid guiding mechanism 4 serves to receive and guide water. Specifically, it includes a liquid guiding box 401 fitted onto the connecting boss 3 in the uppermost planting trough 1, and a liquid guiding box cover 402 detachably connected to the liquid guiding box 401. A water inlet 403 is located at the center of the bottom of the liquid guiding box 401, and a water outlet 404 is located on one side of the bottom of the liquid guiding box 401. The water inlet 403 has a threaded portion for connecting a water pipe, and the water outlet 402 can direct nutrient solution or water into the planting trough 1. When nutrient solution or water is pumped through a water pump and water inlet pipe, the water flow impacts the cover plate 402 of the nutrient solution container, creating splashes. This helps increase the oxygen content in the nutrient solution. To prevent excessive splashing, a limiting ring 405 is protruding from the cover plate 402 corresponding to the water inlet 403. The limiting ring 405 extends towards the water inlet 403 and fits around it, limiting the splashing range and preventing nutrient solution leakage. Simultaneously, the cover plate 402 also provides shade, preventing algae growth in the nutrient solution within the container under light conditions, thus extending the shelf life of the nutrient solution. The nutrient solution in the container 401 can be transported downwards layer by layer through the drainage slots and drainage holes 9 of each layer of the planting trough 1. Water inlet 403 is provided with water box connection holes 406 on both sides. Liquid guide box cover plate 402 is provided with liquid guide box cover plate connection hole 407 corresponding to the position of water box connection hole 406. Water box connection hole 406 and liquid guide box cover plate connection hole 407 are also used to connect the column to connect the liquid guide mechanism to the 4 planting tank 1 as a whole.

[0073] like Figure 13-14 As shown, the planting cover 2 includes a first planting cover 201 and a second planting cover 202 that are adapted for snap-fit ​​connection. The first planting cover 201 and the second planting cover 202 have the same structure and are installed symmetrically by plugging them in. Because the two have the same structure, there is no need to make two sets of molds during production, resulting in low production costs and convenient installation. Specifically, as... Figure 14 As shown, taking the first planting cover 201 as an example, both the first planting cover 201 and the second cover 202 include a cover body. One end of the cover body is provided with a male plug 203, and the other end is provided with a female plug 204 corresponding to the position of the male plug 203. When the first planting cover 201 and the second cover 202 are connected, the male plug 203 can be inserted into the female plug 204. After the first planting cover plate 201 and the second planting cover plate 202 are connected, there is a clearance 205 between them. When several planting troughs 1 are stacked and connected, the side wall of the planting trough 1 can abut against the clearance 205, making the planting cover plate 2 more stable after assembly. The first planting cover plate 201 and the second planting cover plate 202 are not easy to shake. The two sides of the clearance 205 between the first planting cover plate 201 and the second planting cover plate 202 in the top planting trough 1 abut against the side wall of the liquid guiding mechanism 4.

[0074] The planting cover plate 2 is provided with several planting holes 206 spaced apart, which are used to accommodate planting cups for planting plants.

[0075] like Figure 13 , Figure 15-16 As shown, to achieve substrate cultivation, a substrate storage mechanism 13 is detachably connected inside the planting trough 1. For ease of fabrication, installation, and disassembly, in this embodiment, two substrate storage mechanisms 13 are used, positioned opposite each other on either side of the connecting boss 3. The outer shape of the substrate storage mechanism 13 is adapted to the side wall 103 of the planting trough, allowing it to fit snugly inside the planting trough 1 and preventing it from shaking relative to the trough 1 after installation. The substrate storage mechanism 13 is a substrate storage tank used to store plant substrate in substrate cultivation. Its bottom surface has water absorption holes 1301, which allow the planting substrate to absorb nutrient solution. To ensure a gap between the substrate storage mechanism 13 and the bottom wall 102 of the planting trough after installation, allowing for sufficient flow of nutrient solution and facilitating substrate absorption, a support leg 14 is also connected to the bottom of the substrate storage mechanism 13. The support leg 14 also supports the substrate storage mechanism 13 and improves its connection stability.

[0076] By using a snap-fit ​​connection between the first planting cover 201 and the second planting cover 202, and the substrate storage mechanism 13 directly fitted inside the planting trough 1, the disassembly and assembly of the cover 2 and the substrate storage mechanism 13 do not require tools. The assembly is convenient and easy to operate. In hydroponic mode, the inside of the planting trough 1 can be cleaned after separating the first planting cover 201 and the second planting cover 202. In substrate culture mode, the inside of the planting trough 1 can be cleaned after separating the first planting cover 201 and the second planting cover 202 and taking out the substrate storage mechanism 13. The cleaning process is simple and convenient, and the planting trough 1 can be thoroughly cleaned without any dead corners.

[0077] In addition, the first planting cover plate 201 and the second planting cover plate 202 are inclined downward relative to the horizontal surface, so that the planting surface is inclined and the plants grow outward at an angle, which can make full use of the light and further improve the light utilization rate.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
