Description

Technical Field

[0001] This utility model relates to the field of greenhouse equipment technology, and in particular to a spatial three-dimensional soil cultivation system. Background Technology

[0002] Coptis chinensis is a shallow-rooted, low-growing plant with delicate roots that are susceptible to waterlogging. It is not particularly demanding in terms of soil, requiring only moist conditions, but waterlogging must be avoided. Its native environment is karst rock crevices; if exposed to continuous rainfall or flash floods, the roots will rupture if soaked for more than 4 hours, and begin to rot after 24 hours, leading to the plant's withering. Karst landforms are characterized by "many rocks, little soil, and fragmented terrain," with arable land mostly distributed in mountain depressions. These areas are highly susceptible to short-term flooding due to heavy rains during the rainy season.

[0003] Traditional single-layer open-field planting, due to its flat terrain and lack of elevation structures, allows water to directly submerge the roots, resulting in high yield reductions caused by flooding each year. Furthermore, it is severely affected by pests and diseases, requiring the application of large amounts of pesticides, leading to significant pesticide residues. Additionally, the limited arable land per capita in karst regions makes single-layer planting a low-utilization-rate method, which is insufficient to meet the demands of large-scale cultivation.

[0004] The existing greenhouse cultivation technology for Coptis chinensis commonly uses a simple greenhouse combined with multi-layered frames, with each layer holding a fixed planting trough. The light inside the greenhouse relies on natural lighting or timed supplemental lighting. The multi-layered frames are not movable, and the troughs at the bottom of the multi-layered frames are prone to insufficient light due to shading from the upper layers, which affects the growth of Coptis chinensis in the bottom planting troughs.

[0005] Therefore, there is an urgent need to invent a spatial three-dimensional soil cultivation system to solve the above problems. Utility Model Content

The extension direction of the mating rack is in the same direction as the arrangement direction of the two planting slots on the second platform. The mating rack meshes with the output end of the second drive member, and the second drive member can drive the mating rack to move along the extension direction of the mating rack.

[0033] The beneficial effects of this utility model are:

[0034] This utility model provides a spatial three-dimensional soil cultivation system. By setting up protective cavities within a protective shed, multiple planting racks are arranged and stored at intervals along the horizontal and vertical directions within these cavities, forming the basic structure of the system. Each planting rack is equipped with a first platform, a second platform, and a third platform spaced upwards. The first platform can support three horizontally arranged planting troughs, the second platform can support two horizontally arranged planting troughs, and the third platform can support one planting trough. This allows for three-dimensional storage of multiple planting troughs within a space, improving space utilization and increasing the scale of crop cultivation within the protective shed, thereby increasing yield. Simultaneously, by incorporating a control unit and a light intensity detector, the light intensity detector, the second platform, and the third platform are all communicatively connected to the control unit. The light intensity detector detects the light intensity of the planting trough at the first platform and transmits the detection information to the control unit. The control unit then determines the first... If the illuminance of the planting troughs on the platform is not lower than the preset value, it means that the crops in the planting troughs on the first platform can grow under normal light conditions. If the illuminance of the planting troughs on the first platform is lower than the preset value, it means that the crops in the planting troughs on the first platform cannot grow under normal light conditions. The planting troughs on the second and third platforms block the planting troughs on the first platform. At this time, the control unit controls the second and third platforms to drive the corresponding planting troughs to move horizontally. Taking advantage of the fact that the first, second, and third platforms are all open platforms, when the planting troughs on the second and third platforms are moved away, light can pass through the open holes on the second and third platforms and shine on the planting troughs on the first platform, so that the planting troughs on the first platform can grow under normal light conditions again. This ensures that the crops in each planting trough can receive sufficient light and guarantee the normal growth of the crops. Attached Figure Description

[0051] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0052] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] The native environment of *Coptis chinensis* is karst rock crevices. Traditional single-layer open-field cultivation, due to the flat terrain and lack of elevated structures, allows water to directly submerge the roots, resulting in a high yield reduction rate caused by flooding each year. Simultaneously, it is severely affected by pests and diseases, requiring the application of large amounts of pesticides, leading to significant pesticide residues. Furthermore, the per capita arable land area in karst regions is limited, and the single-layer cultivation model has low land utilization, making it difficult to meet the needs of large-scale cultivation.

[0055] The existing greenhouse cultivation technology for Coptis chinensis commonly uses a simple greenhouse combined with multi-layered frames, with each layer holding a fixed planting trough. The light inside the greenhouse relies on natural lighting or timed supplemental lighting. The multi-layered frames are not movable, and the troughs at the bottom of the multi-layered frames are prone to insufficient light due to shading from the upper layers, which affects the growth of Coptis chinensis in the bottom planting troughs.

[0056] To solve the above problems, such as Figures 1-3As shown, this embodiment provides a spatial three-dimensional soil cultivation system. This spatial three-dimensional soil cultivation system includes a protective shed 100, a light intensity detection device 500, multiple planting racks 300, and multiple planting troughs 400. The protective shed 100 has a protective cavity, within which the multiple planting racks 300 are housed and arranged horizontally and vertically. Each planting rack 300 has a first platform 310, a second platform 320, and a third platform 330 spaced apart from bottom to top. The first platform 310, second platform 320, and third platform 330 are all open platforms. The planting troughs 400 are used for planting crops. Platform 310 can support three planting troughs 400 arranged horizontally, second platform 320 can support two planting troughs 400 arranged horizontally, and third platform 330 can support one planting trough 400. Illuminance detection device 500 is used to detect the illuminance of the planting trough 400 at the first platform 310. Illuminance detection device 500, second platform 320 and third platform 330 are all connected to control unit. Second platform 320 and third platform 330 can each drive the corresponding planting trough 400 to move horizontally.

[0057] This spatial three-dimensional soil cultivation system utilizes a protective cavity within a protective shed 100. Multiple planting racks 300 are arranged and stored at intervals along both the horizontal and vertical axes within this cavity, forming the basic structure of the system. Each planting rack 300 contains a first platform 310, a second platform 320, and a third platform 330 arranged at intervals from bottom to top. The first platform 310 can support three horizontally arranged planting troughs 400, the second platform 320 can support two horizontally arranged planting troughs 400, and the third platform 330 can support one planting trough 400. The system enables three-dimensional storage of multiple planting troughs 400 within a space, improving space utilization and increasing the planting scale and yield of crops within the protective shed 100. Simultaneously, by setting up a control unit and a light intensity detector 500, the light intensity detector 500, the second platform 320, and the third platform 330 are all communicatively connected to the control unit. The light intensity detector 500 detects the light intensity of the planting trough 400 at the first platform 310 and transmits the detection information to the control unit. The control unit then determines whether the light intensity of the planting trough 400 at the first platform 310 is sufficient. If the illuminance of the planting trough 400 at the first platform 310 is not lower than the preset value, it means that the crops in the planting trough 400 at the first platform 310 can grow under normal illuminance. If the illuminance of the planting trough 400 at the first platform 310 is lower than the preset value, it means that the planting troughs 400 at the second platform 320 and the third platform 330 are blocking the planting trough 400 at the first platform 310, and the crops in the planting trough 400 at the first platform 310 cannot grow under normal illuminance. At this time, the control unit controls the second platform 320 and the third platform 330. The corresponding planting trough 400 is moved horizontally by the 0-drive mechanism. Taking advantage of the fact that the first platform 310, the second platform 320, and the third platform 330 are all hollow platforms, when the planting troughs 400 at the second platform 320 and the third platform 330 are removed, light can pass through the hollow holes on the second platform 320 and the third platform 330 and shine on the planting trough 400 at the first platform 310. This allows the planting trough 400 at the first platform 310 to grow again under normal light intensity, ensuring that the crops in each planting trough 400 can receive sufficient light and guarantee the normal growth of the crops.

[0058] It should be noted that in this embodiment, the spatial three-dimensional soil cultivation system has three light intensity detectors 500, which are respectively installed on the planting rack 300. Each light intensity detector 500 corresponds to a planting trough 400 at the first platform 310, ensuring that the crops in the three planting troughs 400 at the first platform 310 can grow under normal light conditions. In other embodiments, additional light intensity detectors 500 can be set to detect the light intensity of the planting trough 400 at the second platform 320 to prevent the planting trough 400 at the third platform 330 from blocking the planting trough 400 at the second platform 320. The applicant has verified that one planting trough 400 at the third platform 330 cannot effectively block the two planting troughs 400 at the second platform 320; that is, the planting trough 400 at the third platform 330 will not affect the growth of the crops in the planting trough 400 at the second platform 320. Therefore, in this embodiment, only light intensity detectors 500 are used to detect the light intensity of the planting trough 400 at the first platform 310. Furthermore, the crop used in this embodiment is Coptis chinensis. In other embodiments, the specific type of crop can be adjusted according to actual needs; this embodiment does not impose any specific limitations.

[0059] Understandably, the specific dimensions of the protective shed 100, the planting rack 300, and the planting trough 400 can all be adjusted according to actual needs, and this embodiment does not impose any specific limitations.

[0060] Furthermore, the specific structure and working principle of the control unit are existing technologies and will not be elaborated here.

[0061] As an optional solution, the protective shed 100 has a top sealing cloth 150 and a first traction assembly 110. The protective cavity has an upper opening. The top sealing cloth 150 can switch between a first state where it is stacked together and a second state where it is unfolded in a horizontal direction. The top sealing cloth 150 in the second state is used to seal the upper opening of the protective cavity. The output end of the first traction assembly 110 is connected to one end of the top sealing cloth 150. The first traction assembly 110 is used to drive the top sealing cloth 150 to switch between the first state and the second state.

[0062] In sunny weather, if the illuminance detection device 500 detects that the illuminance of the planting trough 400 at the first platform 310 is lower than the preset value, in addition to adjusting the positions of the planting troughs 400 at the second platform 320 and the third platform 330, the illuminance of the planting trough 400 at the first platform 310 can be increased by opening the upper opening of the protective cavity inside the protective shed 100. Specifically, when the illuminance detection device 500 detects that the illuminance of the planting trough 400 at the first platform 310 is lower than the preset value, the first traction component 110 drives the top sealing cloth 150, which is in the second state, to switch to the first state, thereby opening the previously sealed upper opening and allowing sunlight to directly shine into the protective cavity of the protective shed 100.

[0063] Combination Figure 4 and Figure 5 The specific structure of the first traction assembly 110 is described below. The first traction assembly 110 includes a first driving member 111, a fixed pulley 112, and a transmission belt 113. The output end of the first driving member 111 and the fixed pulley 112 are arranged sequentially along the stacking and unfolding direction of the top sealing cloth 150. The output end of the first driving member 111 and the fixed pulley 112 engage together to tension the transmission belt 113. One end of the top sealing cloth 150 along the stacking and unfolding direction is fixedly connected to the transmission belt 113, and the other end of the top sealing cloth 150 along the stacking and unfolding direction is fixedly connected to the protective canopy 100. The transmission belt 113 can drive the end of the top sealing cloth 150 fixedly connected to the transmission belt 113 to reciprocate along the stacking and unfolding direction. By arranging the output end of the first driving member 111 and the fixed pulley 112 sequentially along the stacking and unfolding direction of the top sealing cloth 150 and tensioning the transmission belt 113 together, the two ends of the top sealing cloth 150 along the stacking and unfolding direction are fixed to the transmission belt 113 and the protective canopy 100 respectively. The first driving member 111 drives the transmission belt to move, thereby driving one end of the top sealing cloth 150 to move, thus achieving the effect of stacking the unfolded top sealing cloth 150 together and unfolding the stacked top sealing cloth 150.

[0064] It should be noted that in this embodiment, the stacking and unfolding direction of the top sealing cloth 150 is longitudinal. In other embodiments, the stacking and unfolding direction of the top sealing cloth 150 can also be adaptively adjusted in the horizontal plane according to actual needs. This embodiment does not impose specific limitations. Moreover, the first driving component 111 is a rotary motor, and the output shaft of the rotary motor is fixed with a transmission gear, which meshes with the transmission belt 113. The rotary motor has a simple structure and stable output power.

[0065] Furthermore, in this embodiment, such as Figure 1 , Figure 4 and Figure 5As shown, the first traction assembly 110 also includes a fixing rod 114, which extends laterally and is fixedly connected to the transmission belt 113 and the top sealing cloth 150 respectively. The top of the protective canopy 100 is provided with a guide rail 140, which extends longitudinally. The fixing rod 114 has a guide slider, which slides in cooperation with the guide rail 140 to improve the stacking and unfolding effect of the top sealing cloth 150.

[0066] During cloudy or rainy weather, if the illuminance detection device 500 detects that the illuminance of the planting trough 400 at the first platform 310 is lower than a preset value, the light intensity cannot be increased by opening the upper opening of the protective cavity inside the protective shed 100. Therefore, this embodiment also provides a supplementary light 130 in the protective shed 100. During cloudy or rainy weather, if it is still necessary to increase the illuminance of the planting trough 400 at the first platform 310, the supplementary light 130 can be turned on to emit light and increase the illuminance.

[0067] In this embodiment, the protective shed 100 has eight supplementary lights 130, which are arranged in two columns along the longitudinal direction, with each column including four supplementary lights 130 arranged sequentially along the longitudinal direction. In other embodiments, the specific number and arrangement of the supplementary lights 130 can be adjusted according to actual needs; this embodiment does not impose specific limitations. In addition, the protective shed 100 has an entrance and exit door 170 for people to enter and exit the protective shed 100 normally.

[0068] In an optional embodiment, the protective shed 100 further includes a side-sealing cloth 160 and a second traction assembly 120. The protective cavity has a side opening. The side-sealing cloth 160 can switch between a third state where it is stacked together and a fourth state where it is unfolded vertically. The side-sealing cloth 160 in the fourth state is used to seal the side opening of the protective cavity. The output end of the second traction assembly 120 is connected to one end of the side-sealing cloth 160, and the second traction assembly 120 is used to drive the side-sealing cloth 160 to switch between the third and fourth states. By providing a side opening in the protective cavity of the protective shed 100 and providing a side-sealing cloth 160 that can switch between a third state where it is stacked together and a fourth state where it is unfolded vertically, and by providing a second traction assembly 120 to drive the side-sealing cloth 160 to switch between the third and fourth states, the effect of controlling the opening and closing of the side opening inside the protective shed 100 is achieved. With the side sealing cloth 160 sealing the side opening, when the temperature inside and outside the protective cavity is inconsistent, the side sealing cloth 160 can be switched from the third state to the fourth state to open the side opening, so that the inside and outside of the protective cavity can be connected to each other and the temperature inside and outside the protective cavity can be balanced.

[0069] It should be noted that opening the upper opening of the protective cavity inside the protective canopy 100 can also balance the temperature inside and outside the protective cavity. However, opening the side opening of the protective cavity, compared to opening the upper opening, can utilize natural wind to increase the temperature balancing rate. Furthermore, the specific structure of the second traction assembly 120 is the same as that of the first traction assembly 110, and for the sake of brevity, it will not be described again here.

[0070] To further improve the automation level of this spatial three-dimensional soil cultivation system, such as Figure 1 and Figure 2 As shown, the spatial three-dimensional soil cultivation system also includes a temperature detection element 600, which is installed inside the protective cavity of the protective shed 100. The temperature detection element 600 and the second traction component 120 are respectively communicatively connected to the control unit. The temperature detection element 600 is used to detect the temperature inside the protective cavity, and the control unit can control the opening and closing of the second traction component 120. When the temperature inside the protective cavity is detected to be lower or higher than a preset value, the temperature detection element 600 transmits the detection information to the control unit. The control unit activates the second traction component 120 according to the detection information to connect the inside and outside of the protective cavity, thereby achieving automatic temperature balance between the inside and outside of the protective cavity.

[0071] As an optional solution, such as Figure 1 and Figure 6 As shown, the spatial three-dimensional soil cultivation system also includes a humidity detection device 700 and a liquid supply unit 200. Each planting trough 400 is equipped with at least one humidity detection device 700, which detects the humidity of the soil within the planting trough 400. Both the liquid supply unit 200 and the humidity detection device 700 are communicatively connected to the control unit. The liquid supply unit 200 can independently supply planting solution to each planting trough 400, and the control unit can control the opening and closing of the liquid supply unit 200. By installing at least one humidity detection device 700 in each planting trough 400 and connecting both the liquid supply unit 200 and the humidity detection device 700 to the control unit, the liquid supply unit 200 can independently supply planting solution to each planting trough 400, achieving automated liquid replenishment for each planting trough 400. When the planting trough 400 lacks planting solution, the humidity detection element 700 corresponding to that planting trough 400 detects that the humidity inside the planting trough 400 is lower than a preset value. The humidity detection element 700 transmits the detection information to the control unit, and the control unit activates the liquid supply unit 200 based on the detection information. The liquid supply unit 200 delivers the planting solution to the corresponding planting trough 400. It should be noted that in this embodiment, the planting solution is water. In other embodiments, the specific composition of the planting solution can be adjusted according to actual needs; this embodiment does not impose specific limitations.

[0072] In an alternative embodiment, such as Figure 6As shown, each planting trough 400 is equipped with a burette 410. The input end of the burette 410 is connected to the output end of the liquid supply unit 200. The burette 410 extends along the length of the planting trough 400, and multiple drip ports 411 are spaced apart along the length of the planting trough 400 on the burette 410. By having burettes 410 extending along the length of the planting trough 400 on each planting trough 400, the output end of the liquid supply unit 200 is connected to the input end of the burette 410, and multiple drip ports 411 are spaced apart along the length of the burette 410, uniform titration of the planting solution can be achieved within the planting trough 400, ensuring the titration effect of the planting solution. It should be noted that in this embodiment, the burette 410 has 17 drip ports 411 spaced apart along the length of the planting trough 400. In other embodiments, the specific number of drip ports 411 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0073] In addition, each planting trough 400 has multiple drainage ports 420 spaced apart along its length on the bottom. By providing multiple drainage ports 420 spaced apart along the length of the bottom of each planting trough 400, the accumulation of planting solution at the bottom of the planting trough 400 can be avoided, preventing excessive soil moisture within the planting trough 400. It should be noted that in this embodiment, each planting trough 400 has 17 drainage ports 420 spaced apart along its length on the bottom. In other embodiments, the specific number of drainage ports 420 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0074] Optionally, such as Figure 7As shown, the second platform 320 has two sets of drive structures 321, each set of drive structures 321 corresponding to a planting trough 400. Each set of drive structures 321 includes a second drive member 3211 and a mating rack 3212. The second drive member 3211 is fixed on the second platform 320, and the mating rack 3212 is fixed on the planting trough 400. The extension direction of the mating rack 3212 is in the same direction as the arrangement direction of the two planting troughs 400 at the second platform 320. The mating rack 3212 meshes with the output end of the second drive member 3211, and the second drive member 3211 can drive the mating rack 3212 to move along the extension direction of the mating rack 3212. By configuring a second driving component 3211 and a mating rack 3212 that mesh and transmit power to each other, the second driving component 3211 is mounted on the second platform 320, and the mating rack 3212 is mounted on the corresponding planting trough 400. The extending direction of the mating rack 3212 is aligned with the arrangement direction of the two planting troughs 400 on the second platform 320, enabling the planting trough 400 to move towards or away from the other planting trough 400. It should be noted that in this embodiment, the second driving component 3211 is a rotary motor, and the output shaft of the rotary motor is equipped with a mating gear, which meshes with the mating rack 3212 for transmission. The rotary motor has a simple structure and stable output power.

[0075] To further improve the driving effect of the planting trough 400, a roller 430 is provided on the lower end face of the planting trough 400, and the roller 430 makes rolling contact with the second platform 320 or the third platform 330. By providing the roller 430 on the lower end face of the planting trough 400, the sliding contact between the planting trough 400 and the second platform 320 or the third platform 330 can be replaced with the rolling contact between the roller 430 and the second platform 320 or the third platform 330, which greatly reduces friction and simplifies the driving difficulty of the planting trough 400.

[0076] Understandably, the third platform 330 also has a drive structure 321, which will not be elaborated on here for the sake of brevity.

[0077] Combination Figure 8The specific structure of the liquid supply unit 200 is described below. The liquid supply unit 200 includes a storage tank 210, a delivery pipeline 220, a shut-off valve 230, and a drive pump. The storage tank 210 is used to store the planting solution. The delivery pipeline 220 includes a main pipeline and multiple branch pipelines connected to each other. The opening of the main pipeline is connected to the output end of the storage tank 210. The opening of each branch pipeline is corresponding to a planting trough 400. The shut-off valve 230 is located between the main pipeline and the multiple branch pipelines. The shut-off valve 230 is communicatively connected to the control unit. The shut-off valve 230 can individually control the connection and disconnection between each branch pipeline and the main pipeline. The drive pump is installed on the main pipeline and is communicatively connected to the control unit. The drive pump is used to drive the planting solution in the storage tank 210 to flow to the branch pipelines.

[0078] The planting solution is stored in a storage tank 210, and a delivery pipeline 220, including a main pipeline and multiple branch pipelines, is installed. The main pipeline is connected to the storage tank 210, and the multiple branch pipelines are connected to the burettes 410 in the planting troughs 400. A shut-off valve 230 controls the connection and disconnection between the main pipeline and each branch pipeline in the delivery pipeline 220. A drive pump drives the flow of the planting solution in the storage tank 210. When the planting trough 400 needs to be replenished with planting solution, the control unit controls the corresponding shut-off valve 230 to open the main pipeline and the corresponding branch pipeline. At the same time, the control unit starts the drive pump, causing the drive pump to drive the planting solution in the storage tank 210 to flow sequentially through the main pipeline and branch pipelines before flowing into the burettes 410 in the corresponding planting trough 400 to complete the titration replenishment of the planting solution.

[0079] In addition, in this embodiment, the liquid supply unit 200 also includes a support frame 240, which is used to support the liquid storage tank 210 to improve the protection of the liquid storage tank 210.

[0080] In one optional embodiment, the spatial three-dimensional soil cultivation system also includes cameras and a video platform. The cameras capture real-time images of the crops growing within the protective greenhouse 100. The video data captured by the cameras is transmitted to the video platform via a 5G network, making it available for access and query by authorized personnel, or for public viewing as a live stream. Simultaneously, the video can also be connected to the agricultural research institute's knowledge base system for querying crop growth information and diagnosing and controlling foliar diseases and pests. It should be noted that the communication and transmission principles between the cameras and the video platform are existing technologies and will not be elaborated upon here.
