[0036] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The following combination Figures 1 to 3 , the three-dimensional cultivation device provided by the utility model embodiment is described in detail through specific embodiments and application scenarios.

[0038] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a three-dimensional cultivation device, comprising: a column 1, a water pump 2, a liquid return tank 3 and a multi-layer cultivation tank 4;

[0039] The column 1 is connected to the return liquid tank 3, and the multi-layer cultivation tanks 4 are respectively connected to the column 1 and arranged in sequence from top to bottom; according to the arrangement order from top to bottom, the area of ​​each layer of cultivation tank 4 gradually increases;

[0040] An infusion channel is formed in the column 1, and the water pump 2 is connected to the infusion channel. The water pump 2 is used to pump the nutrient solution in the return tank 3 to the cultivation tank 4 on the uppermost layer through the infusion channel;

[0041] The nutrient solution can overflow in sequence along the cultivation troughs 4 arranged from top to bottom, and finally flow back into the return liquid tank 3 .

[0042] It can be understood that the return liquid tank 3 and the cultivation tank 4 are both trough-like structures with an open top. The return liquid tank 3 is used to store and collect the nutrient solution required for plant growth. The nutrient solution contains multiple elements, such as nitrogen, phosphorus, potassium and other macroelements and calcium, magnesium, sulfur and other medium elements and iron, manganese, zinc and other trace elements.

[0043] The cultivation troughs 4 are used to cultivate plants in soil or soilless cultivation. Since the multiple layers of cultivation troughs 4 are arranged sequentially from top to bottom, the arrangement of the cultivation troughs 4 in two adjacent layers can be set according to actual needs. When the nutrient solution in the cultivation troughs 4 in the upper layer is full, the nutrient solution overflowing from the cultivation troughs 4 in the upper layer can automatically fall into the cultivation troughs 4 in the lower layer under the action of its own gravity.

[0044] For example, each cultivation trough 4 may be provided with a 10-20 mm trough edge. When the nutrient solution in the cultivation trough 4 overflows, a circular waterfall may be formed in the cultivation trough 4, thereby ensuring the aesthetic appearance of the overflow.

[0045] For example, a plurality of overflow ports can be provided on the edge of each cultivation trough 4, and the plurality of overflow ports are arranged in sequence along the circumference of the cultivation trough 4, and each overflow port has a certain height relative to the bottom of the cultivation trough 4. This design can ensure that a certain amount of nutrient solution can be retained in the cultivation trough 4, and realize the overflow of the nutrient solution through multiple overflow ports at the same time, and can also ensure the aesthetics of the overflow.

[0046] The cultivation troughs 4 can be circular, triangular, or rectangular. The structural types of the cultivation troughs 4 at each layer can be the same or different, and there is no specific limitation on this. The only requirement is that the areas of the cultivation troughs 4 at each layer gradually increase as they are arranged from top to bottom.

[0047] For example, the cultivation trough 4 is specifically provided with three layers, and these three layers of cultivation troughs 4 are all circular troughs. For example, the cultivation trough 4 is specifically provided with three layers, and these three layers of cultivation troughs 4 are respectively circular troughs, triangular troughs, and rectangular troughs. Of course, the number of layers and structural types of the cultivation trough 4 can also be other arrangements, which are not listed here one by one.

[0048] Since the multi-layer cultivation troughs 4 are arranged in sequence from top to bottom, and the area of ​​each layer of cultivation troughs 4 gradually increases in the order of arrangement from top to bottom, this design ensures that the multi-layer cultivation troughs 4 form a spindle-shaped cultivation structure with a crown shape. When plants are cultivated based on this spindle-shaped cultivation structure, relatively high yields and better quality can be obtained.

[0049] Furthermore, the water pump 2 can be set inside the return liquid tank 3 or outside the return liquid tank 3. There is no limitation on this. It only needs to ensure that the water pump 2 can absorb the nutrient solution in the return liquid tank 3 when working, and pump the nutrient solution along the infusion channel toward the cultivation tank 4 on the top layer.

[0050] At the same time, the bottom end of the column 1 is connected to the return trough 3. The column 1 can be configured to be either vertical or inclined, without limitation. After the multi-layer cultivation troughs 4 are connected to the columns 1, the center of gravity of these components should be ensured to be distributed above the return trough 3 to prevent the entire three-dimensional cultivation device from tipping over due to an unstable center of gravity.

[0051] As can be seen from the above, the three-dimensional cultivation device provided by the present invention is provided with a column 1 based on the return liquid trough 3, and multiple layers of cultivation troughs 4 arranged in sequence from top to bottom are provided on the column 1. In actual application, the nutrient solution in the return liquid trough 3 can be sucked by the water pump 2, and then the nutrient solution in the return liquid trough 3 is pumped to the cultivation trough 4 on the uppermost layer by using the infusion channel in the column 1. As the nutrient solution in the cultivation trough 4 on the uppermost layer gradually increases, the nutrient solution will overflow into the cultivation trough 4 on the lower layer, and gradually overflow along the cultivation troughs 4 on each layer in the order of arrangement from top to bottom, and finally flow back into the return liquid trough 3, thereby realizing the supply cycle of the nutrient solution. This design makes full use of the arrangement structure of the cultivation troughs 4 on each layer, which not only ensures the normal replenishment of the nutrient solution in the cultivation troughs 4 on each layer, maximizes the oxygen content in the nutrient solution, but also simplifies the return waterway structure of the nutrient solution, realizes the simplified design of the entire device, and reduces the cultivation cost.

[0052] At the same time, since the area of ​​each layer of cultivation troughs 4 gradually increases in the order of arrangement from top to bottom, each layer of cultivation troughs 4 will not be excessively blocked by the cultivation troughs 4 on the upper layer, ensuring that the plants on each layer are fully exposed to light, maximizing the use of light resources, and making it convenient for residents to cultivate plants with or without soil indoors.

[0053] In some embodiments, as Figure 2 As shown, the three-dimensional cultivation device further includes: a rotary support 5; the rotary support 5 is supported on the bottom of the liquid return tank 3.

[0054] It can be understood that since the swivel support 5 is supported on the bottom of the return liquid trough 3, the return liquid trough 3 can be driven to rotate by the swivel support 5, and the return liquid trough 3 will drive each cultivation trough 4 to rotate synchronously through the column 1 to adjust the orientation of the plants in each cultivation trough 4, thereby ensuring the uniformity of light received by the plants in each cultivation trough 4.

[0055] In some embodiments, as Figure 2 and Figure 3 As shown, the rotary support 5 includes a base 51, a drive motor 52 and a rotation support member 53; the rotation support member 53 is rotatably provided on the base 51 and supported on the bottom of the return liquid tank 3;

[0056] The driving motor 52 is disposed on the base 51 and is in transmission connection with the rotating support member 53 to drive the rotating support member 53 to rotate around the vertical axis.

[0057] It is understandable that the drive motor 52 can be a servo motor, which drives the rotating support 53 to rotate in sequence according to the set angle, thereby controlling the cultivation trough 4 to rotate synchronously in sequence according to the set angle to adjust the orientation of the plants in each cultivation trough 4.

[0058] The rotating support 53 can be configured in a disc shape. The rotating support 53 is rotatably connected to the base 51 through a vertically distributed transmission shaft. A plane bearing is sleeved on the transmission shaft, and the plane bearing is supported between the rotating support 53 and the base 51 along the vertical direction.

[0059] The drive motor 52 is connected to the corresponding transmission shaft of the rotating support member 53 through a transmission assembly 54. For example, the transmission assembly 54 includes a first pulley, a second pulley, and a synchronous belt. The first pulley is coaxially connected to the output end of the drive motor 52, the second pulley is coaxially connected to the transmission shaft, and the synchronous belt is wound between the first pulley and the second pulley.

[0060] In some embodiments, as Figure 2 As shown, the base 51 includes a supporting portion 511 and an extending portion 512; the rotating support member 53 is rotatably provided on the supporting portion 511;

[0061] The extension portion 512 is provided on one side of the support portion 511 and is configured to be embedded in a corner of a room; the drive motor 52 is vertically distributed and provided on the upper side of the extension portion 512 .

[0062] It is understandable that when the three-dimensional cultivation device is placed indoors, by embedding the extension portion 512 of the base 51 in the corner of the room, effective utilization of the indoor corner space can be achieved, which not only ensures the aesthetics of the three-dimensional cultivation device when placed indoors, but also ensures that the three-dimensional cultivation device does not occupy too much indoor space.

[0063] For example, when the liquid return tank 3 is a circular tank, the supporting portion 511 of the base 51 may be configured to be circular, and the extending portion 512 of the base 51 may be configured to be triangular.

[0064] In some embodiments, each layer of cultivation troughs 4 can be movably arranged on the column 1 along the extension direction of the column 1. The user can adjust the distance between two adjacent layers of cultivation troughs 4 according to actual needs to avoid the plants cultivated in the lower layer of cultivation troughs 4 being blocked by the upper layer of cultivation troughs 4.

[0065] For example, the peripheral wall of the column 1 is provided with an external thread, and the column 1 is equipped with multiple limit nuts in a threaded engagement with the external thread. The multiple limit nuts are correspondingly arranged on the lower sides of the multiple cultivation troughs 4. Each limit nut is supported on the lower side of its corresponding cultivation trough 4, and the middle portion of each cultivation trough 4 is sleeved on the outer side of the column 1 to enable the cultivation trough 4 to move relative to the column 1. In this way, the installation height of each layer of cultivation troughs 4 can be limited based on the installation height of each limit nut relative to the column 1, and the distance between two adjacent layers of cultivation troughs 4 can be adjusted.

[0066] In some embodiments, in order to ensure the aesthetics of the three-dimensional cultivation device when arranged indoors, the cultivation trough 4 is provided with decorative lights, which are arranged along the circumference of the cultivation trough 4 .

[0067] For example, the decorative light may be a light strip, which is extended along the circumference of the cultivation trough 4 .

[0068] For example, the decorative light may be a plurality of light emitting diodes, which are connected in series and arranged along the circumference of the cultivation trough 4 .

[0069] Of course, in this embodiment, a fill light can also be set at the bottom of the cultivation trough 4, and the fill light can be used to emit light to the cultivation trough 4 in the lower layer to ensure that the plants cultivated in the cultivation trough 4 in the lower layer receive light uniformly.

[0070] In some embodiments, as Figure 1 and Figure 2 As shown, for any two adjacent layers of cultivation troughs 4, the vertical projection of the cultivation trough 4 in the upper layer is located within the area where the vertical projection of the cultivation trough 4 in the lower layer is located. This design ensures that the multi-layer cultivation troughs 4 form a spindle-shaped cultivation structure with a tree crown shape, which is conducive to ensuring the growth state of plants in the cultivation troughs 4 on each layer.

[0071] In some embodiments, as Figure 1 and Figure 2 As shown, the return tank 3 and the cultivation tank 4 are both circular tanks, and the return tank 3 and each cultivation tank 4 are coaxially arranged relative to the column 1. This design ensures that the multi-layer cultivation tank 4 forms a spindle-shaped cultivation structure that is closer to the crown shape, while ensuring the overall aesthetics of the three-dimensional cultivation device.

[0072] In some embodiments, in order to ensure the aesthetics of the overall shape of the three-dimensional cultivation device, the cultivation troughs 4 may be arranged in sequence from top to bottom around a spiral trajectory relative to the column 1 .

[0073] In some embodiments, as Figure 1 and Figure 2 As shown, the water pump 2 is arranged in the liquid return tank 3, the inlet end of the water pump 2 is arranged on the side of the water pump 2, and the outlet end of the water pump 2 is arranged at the top of the water pump 2; the column 1 is arranged on the water pump 2, and the infusion channel extends to the bottom end of the column 1 and is connected to the outlet end of the water pump 2.

[0074] It is understandable that in this embodiment, the water pump 2 can be used to provide a mounting support for the column 1. This design not only meets the pumping demand of the water pump 2 for the nutrient solution, but also simplifies the overall design structure of the three-dimensional cultivation device.

[0075] In some examples, the return liquid trough 3 and the cultivation trough 4 are both circular troughs, the water pump 2 is arranged in the middle area of ​​the return liquid trough 3, the column 1 is installed on the water pump 2 in a vertically distributed form, and the return liquid trough 3 and each cultivation trough 4 are coaxially arranged relative to the column 1.

[0076] In some embodiments, as Figure 1 and Figure 2 As shown, the three-dimensional cultivation device also includes a nozzle 6, which is used to spray nutrient solution into the cultivation trough 4; the nozzle 6 is arranged in the top layer of the multi-layer cultivation trough 4 and is connected to the end of the infusion channel away from the water pump 2.

[0077] It is understandable that the nozzle 6 can be a spherical nozzle or a shower nozzle; the nutrient solution is sprayed to the top layer of the multi-layer cultivation trough 4 through the nozzle 6, which not only ensures the uniformity of the nutrient solution spraying, but also ensures the aerobic contact of the nutrient solution, and can also increase the ornamental effect of the three-dimensional cultivation device.

[0078] The nozzle 6 can be configured to be coaxial with the column 1, the bottom end of the nozzle 6 is connected to the infusion channel, and the top end of the nozzle 6 is used for spraying the nutrient solution.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
