Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, specifically a plant cultivation system. Background Technology

[0002] To overcome the limitations of space, light, water, and nutrients in natural planting and to improve planting efficiency, existing plant factories and planting systems used for centralized production or intelligent planting often set up targeted culture structures and nutritional conditions according to the target plant type to achieve high planting production efficiency. Especially in cases of row planting or high-density planting based on seed selection and arrangement, the fundamental role of sowing quality in the planting process cannot be ignored; that is, effective seed selection and controlled distribution are key factors affecting plant yield and quality. For example, forage planting generally refers to grass or other herbaceous plants for livestock consumption. Forage has strong regenerative ability, can be harvested multiple times a year, and is rich in various trace elements and vitamins, thus becoming the first choice for livestock feed. The quality of forage varieties directly affects the economic benefits of animal husbandry. In a broad sense, forage includes green fodder and crops. Ideally, forage should have vigorous growth, tender texture, high yield per unit area, strong regenerative ability, multiple harvests per year, good palatability for livestock, and nutritional content rich in high-quality protein, adequate phosphorus and calcium necessary for bone growth, and abundant vitamins.

[0003] The forage cultivation process includes selecting the planting time, seed treatment and screening, sowing, and planting. Most existing plant factories or planting systems rely on vertical farming, which involves building multiple layers of planting racks vertically, placing planting trays on these racks, and using the numerous planting pits in each tray to cultivate plant seedlings. Suitable conditions are then created, providing the plants with appropriate temperature, humidity, and light levels to ensure vigorous growth. The planting trays can be used to grow forage, vegetables, etc., as needed. This type of cultivation typically takes place in a closed, managed facility. Due to the suitable growing conditions and the protection from natural disasters and pests, coupled with the unlimited expansion of vertical space, the yield per unit area in vertical farming is several times that of the original land area, significantly increasing productivity. Soilless cultivation technology is commonly used to grow forage. This involves cultivating forage indoors or outdoors using soilless cultivation devices, allowing the forage to grow naturally. This method is often called open cultivation. However, the growth of the forage is still affected by the natural environment, and this method usually lacks automated control, resulting in low cultivation efficiency and low yield.

[0004] Among the existing technical solutions for crop cultivation based on plant factories and planting systems, patent publication number CN113317065A discloses a fully automatic three-dimensional forage planting device, which includes several planting units. Each pair of adjacent planting units is symmetrically distributed with the forage transport line as the center. Both the planting units and the forage transport line are located between two parallel guide rails. Each planting unit includes a planting frame and a forage harvester. Both parallel guide rails are equipped with robotic arms. The planting frame is equipped with several planting trays, and the number of planting trays is equal to the number of days in the forage production cycle. Patent CN109076886A discloses a large-scale fully automated forage planting system, which includes an automated planting warehouse set up in a sunroom, a planting tray inlet roller conveyor, an automatic seeding device, an automatic planting tray transport vehicle, and a planting tray outlet roller conveyor. The automatic seeding device is set on the planting tray inlet roller conveyor. The planting tray inlet roller conveyor and the planting tray outlet roller conveyor are respectively connected to the automated planting warehouse. The automated planting warehouse includes shelves and a control unit. The control unit controls the automatic planting tray transport vehicle to store or retrieve planting trays from the automated planting warehouse. The shelves integrate an automatic fertilization device and a spraying device. The technical solution of the aforementioned patent is mainly based on the relative positional arrangement of the planting rack and the harvesting device to automate the planting and harvesting of forage. Combined with light and nutrient supply, it achieves efficient production of forage and other crops. However, the planting trays used to arrange the forage need to be moved into the planting system for cultivation after the sowing preparation is completed, and then moved out of the planting system for the harvesting process after cultivation is completed. This requires additional space and operational resources for the preparation and movement of the planting trays, resulting in a tight space layout for the plant factory or planting system. Furthermore, the sowing quality of the seeds arranged in the planting trays mainly depends on the screening and arrangement process, and cannot be adjusted specifically based on changes in cultivation needs and conditions.

[0005] Patent CN108029286B discloses a periodically adjustable seeding device. The patent's technical solution is based on a rotary seeding structure combined with the conveying speed of the receiving surface to control and adjust the seeding speed to ensure uniform seeding. However, there is a significant height difference between the crop seeds output from the rotary seeding drum and the surface of the receiving seed, causing the seeds output from the fixed discharge hole of the rotary seeding drum to undergo secondary movement on the receiving surface, affecting seeding accuracy and quality. Furthermore, the fixed-diameter discharge hole can become clogged or congested due to seeds in different postures, resulting in uneven seeding.

[0006] Based on the above analysis, in existing technical solutions for crop cultivation based on plant factories or planting systems, the schemes in which planting trays containing crops or crop seeds are moved relative to the planting rack at different planting stages to achieve sowing, cultivation, and harvesting will occupy additional space, which is not conducive to the compact layout of planting space to improve crop yield per unit area. The components used for crop seed screening and sowing are mostly fixed structures, which makes it impossible to make targeted adjustments to crop seed screening and sowing according to changes in cultivation objectives and cultivation conditions to achieve intelligent sowing with automatic feedback.

[0007] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0008] To address at least some of the shortcomings of existing technologies, this application provides a plant cultivation system. The system includes a main frame for arranging planting equipment. The main frame is configured as a multi-layered structure extending axially and beyond a predetermined direction, allowing growth belts for carrying crop seeds or crops to be arranged in layers within the multi-layered structure of the main frame and to reciprocate along the axial direction of the main frame. With planting equipment for sowing, harvesting, and cultivation arranged axially on the main frame, the system is configured with several different operating modes. These operating modes differ in at least one or more of the following: crop growth stage, crop growth state, and growth belt movement mode. This allows the system to achieve integrated intelligent sowing, automatic cultivation, and automatic harvesting throughout the entire process by alternating the use of several operating modes.

[0009] To address the problem in existing technologies where local structures used for crop placement need to be moved in or out of the planting space at different planting stages, thus occupying planting space and increasing system complexity and workload, this application confines the growth belt used for crop placement within the arrangement range of the main frame. During different planting stages such as sowing, cultivation, and harvesting, the growth belt reciprocates relative to the planting equipment arranged on the main frame, occupying a local space to complete the sowing, cultivation, and harvesting processes. This eliminates the need for auxiliary components around the main frame for sowing or harvesting, resulting in a compact structure and easy operation. Furthermore, the extension direction of the main frame is consistent with the reciprocating motion direction of the growth belt, allowing the main frame to provide a three-dimensional planting space for the growth belt and crops based on a multi-layered structure. This enables the plant planting system of this application to significantly increase yield per unit area based on a compact structure.

[0010] Addressing the issue that existing planting equipment often employs a fixed structure, making it unable to adapt to changes in cultivation objectives and conditions, this application's plant cultivation system, based on a compact layout of the main frame structure and planting equipment, incorporates several operating modes for different planting stages. These modes are determined by the different growth states of the crops and the movement patterns of the growth belts. Specifically, the crop growth states include, but are not limited to, the seed stage, the cultivation stage, and the maturity stage. The movement patterns of the growth belts include, but are not limited to, the first to fourth movement patterns, which are determined based on the movement state and range of the growth belts. These determined operating modes can be specifically designed according to the interaction between the growth belts and the planting equipment, enabling the system to achieve modern, intensive production of forage, vegetables, and other crops through the alternating use of these operating modes, including intelligent sowing, automatic cultivation, and automatic harvesting.

[0011] Preferably, the system has a drive mechanism on one side of the main frame axial direction for controlling the movement mode of the growth belts. The drive mechanism is arranged vertically to the main frame axial direction to cover the multi-layered structure of the main frame, allowing it to control the movement mode of different layers of growth belts within the main frame according to different operating modes. To improve the utilization rate of vertical space in the plant cultivation system of this application and increase yield per unit area, the main frame for arranging planting equipment and plants in the plant cultivation system of this application is configured as a multi-layered structure. Each layer of the multi-layered structure can be equipped with growth belts for supporting crops for cultivation and movement. The growth belts extend along the axial direction of the main frame, so the planting equipment that acts on the growth belts or the crops arranged on them can provide sowing, driving, and nutrient conditions in a manner perpendicular to or parallel to the axial direction. During various planting stages—sowing, cultivation, and harvesting—the movement range of the growth belts can be limited to the arrangement range of the main frame, ensuring the overall compactness of the structure. The drive mechanism can control the growth belts located on each layer of the main frame separately, allowing the movement mode of the growth belts to adapt to the planting stage of the plants carried by the growth belts, thereby improving the functional applicability of the drive mechanism of this application.

[0012] Preferably, the system configures at least one end of the main frame axially as an equipment area for arranging planting equipment and the middle of the main frame as a planting area for arranging crop seeds or crops, allowing the growth belt to carry the crop seeds or crops and move periodically between the equipment area and the planting area of ​​the main frame. A separating component is arranged at the boundary between the equipment area and the planting area on the main frame. The separating component changes its positional relationship with the growth belt by moving relative to the main frame, enabling the separating component to physically separate the equipment area and the planting area based on its relative movement to the main frame. Since crops interact with different planting equipment at different planting stages, to ensure the rational arrangement of the planting equipment on the main frame, the planting equipment is arranged in zones or layers on the main frame. This allows the main frame to be divided into different functional areas based on the different planting equipment or the applicable planting stage, for example, a planting area for the cultivation process and an equipment area for the sowing and harvesting process. This allows the growth belt to carry the crops and move between the different functional areas of the main frame to achieve the interaction between the planting equipment and the crops at different planting stages.

[0013] Preferably, the system has a sowing mechanism for planting on the growing belt and a harvesting mechanism for harvesting arranged on one side of the main frame's axial direction. The sowing mechanism and the harvesting mechanism change their positional relationship relative to the growing belt by moving relative to the main frame, so that the system can call the sowing mechanism or the harvesting mechanism by changing their positional relationship relative to the growing belt. To avoid unnecessary interference between the planting equipment and the growing belt or the crops carried on the growing belt, the planting equipment that directly interacts with the growing belt or crops is configured with an adjustable structure, for example, a first position close to the growing belt and crops, and a second position far from the growing belt and crops, so that the adjustment of the planting equipment in the first and second positions can be adapted to different planting stages.

[0014] Preferably, the growth belt is configured as a tracked structure that rotates around the width direction perpendicular to the axial direction and height direction of the main frame, allowing the growth belt to reciprocate relative to the planting equipment along the axial direction of the main frame based on rotational motion in different directions. To save layout space and effectively realize the reciprocating motion of the growth belt, the arrangement of the growth belt relative to the main frame in this application can be configured as a rotary tracked structure, allowing the growth belt to control its movement direction relative to the axial direction based on clockwise and counterclockwise motion to achieve different movement modes, so that the movement mode of the growth belt corresponds to the needs of different operation modes. The movement modes of the growth belt are set according to different rotational motion directions and dynamic and static states, with first to third movement modes corresponding to the sowing process, harvesting process, and cultivation process. The movement modes of the growth belt are also set according to the way the growth belt can move out or in from one side of the main frame axial direction, with a fourth movement mode suitable for intervention and maintenance processes.

[0015] Preferably, the system is configured with first to fourth operating modes corresponding to different crop growth stages, namely the sowing process, cultivation process, harvesting process, and intervention and maintenance process. When the system is in the first operating mode, the processor obtains the preparation status of the sowing mechanism based on the sensing unit. In response to a signal indicating that the sowing mechanism has completed its self-check, the processor controls the drive mechanism based on the drive unit to activate the growth belt in the first motion mode and maintain the sowing speed set in the cultivation plan. In response to a signal indicating that the sowing mechanism has completed its preparation, the processor controls at least a portion of the sowing mechanism based on the sowing unit to move from a constrained position away from the growth belt to a sowing position close to or in contact with the growth belt, enabling the sowing mechanism to arrange crop seeds on the growth belt under controlled sowing parameters.

[0016] Preferably, when the system is in the first operating mode, in response to a signal obtained by the sensing unit indicating that the arrangement parameters and / or density parameters of the crop seeds sown on the growth belt surface do not match the range of parameters set in the cultivation plan, the processor controls the sowing mechanism based on the sowing unit to adjust the sowing parameters, so that the row and column parameters and / or density parameters of the crop seeds on the growth belt return to the range of parameters set in the cultivation plan. Based on configuring several operating modes to suit different planting stages, the plant planting system of this application can, through the collaborative processing of the processor and various functional units, realize the adjustment of the interaction parameters between the planting equipment and the growth belt, as well as between the planting pen and the crop. For example, for the first operating mode applicable to the sowing process, to ensure the sowing quality of the crop seeds on the growth belt, the processor can obtain the sowing parameters of the crop seeds on the growth belt based on the sensing unit, so that the deviation between these sowing parameters and the set sowing parameters of the cultivation plan is used as the control input parameter of the sowing mechanism. That is, the sowing mechanism can adjust the local structure or control parameters of the sowing mechanism based on feedback control, so that the sowing mechanism can arrange the crop seeds on the growth belt in a manner that conforms to the set sowing parameters and the set sowing parameter range. Thus, the plant planting system of this application can effectively control the sowing parameters to achieve uniform sowing. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] This application proposes a plant cultivation system, particularly a uniformly sown plant cultivation system, and especially a fully automated plant cultivation system. The plant cultivation system of this application can be used for the fully automated production process of sowing, cultivating, and harvesting crops such as forage grasses and vegetables. Taking forage grass as an example, high-quality forage grasses are high in yield, protein, and minerals, with a high energy conversion rate, making them far more valuable as feed than grains. Forage grasses in my country are mainly herbaceous plants, but also include vines, semi-shrubs, and shrubs, primarily belonging to different families and genera such as Leguminosae, Poaceae, Polygonaceae, Amaranthaceae, Asteraceae, and Cucurbitaceae. The seed bodies of forage grasses include not only the seeds but also the tubers and rhizomes used for cultivation and propagation due to climatic conditions. To ensure the scientific nature of forage grass cultivation, the selection of forage grass species and varieties should consider the climate, sunlight, soil conditions of the region where the forage grass is introduced, the forage grass utilization method, and the adaptability of the forage grass varieties. For example, the China Perennial Cultivated Grass Species Regionalization divides my country into 9 cultivation regions and 40 sub-regions, enabling the introduction of forage grass species and varieties to be rationally determined based on this regionalization to adapt to the corresponding climate and ecological environment of the planting site.

[0025] To overcome the limitations of space, light, water, and nutrients in natural planting conditions and improve planting efficiency, existing plant factories and planting systems used for centralized production or intelligent planting often set targeted cultivation structures and nutrient conditions according to the target plant type to achieve high planting production efficiency. This is especially true when planting in rows or at high density based on seed selection and arrangement, such as forage grasses and vegetables planted based on seed bodies. The fundamental role of sowing quality in the growth process cannot be ignored; that is, effective seed selection and controlled distribution are key factors affecting plant yield and quality. Therefore, to improve the planting quality and production efficiency of forage grasses and other crops, the plant planting system of this application simulates and optimizes the planting process of forage grasses and other crops under natural conditions based on a planting factory-style planting system. Based on the design adjustments of the sowing mechanism 2 and the planting mechanism, the sowing quality and cultivation efficiency are improved, enabling the plant planting system of this application to realize the integrated operation of intelligent sowing, automatic cultivation, and automatic harvesting of forage grasses, vegetables, and other crops.

[0026] like Figure 1 As shown, the plant cultivation system of this application is equipped with a main frame 1 for arranging crops and planting equipment. The main frame 1 provides space for crop cultivation and corresponding planting equipment based on a frame-type layered structure and / or partitioned structure, enabling the planting equipment of the plant cultivation system to complete the entire process of sowing, cultivation, and harvesting of crops. To overcome the shortcomings of existing technologies where the planting trays used for arranging crops or crop seeds are moved in and out of the relative arrangement structure at each stage of planting, resulting in increased space occupation and workload, the plant cultivation system of this application provides several layered or partitioned spaces for arranging crops and planting equipment based on the main frame 1. The movement of the planting trays used for arranging crops or crop seeds relative to the main frame 1 at each stage of planting is limited to the arrangement range of the main frame 1. This ensures the compactness of the system layout in each stage of planting, saving planting space and increasing the yield per unit area of ​​the plant factory using the plant cultivation system of this application.

[0027] like Figure 1 and Figure 2As shown, the main frame 1 is configured as a multi-layered frame structure extending along a predetermined direction, with an axial direction and a width direction perpendicular to the axial direction. The height direction is the direction of gravity, and the width direction is perpendicular to both the axial and height directions. The plant cultivation system has a device area for arranging planting equipment at at least one end of the main frame 1 along its axial direction, allowing the planting equipment to operate on the planting area located in the middle of the main frame 1 to achieve crop sowing, cultivation, and harvesting. Each layer of the main frame 1 has growth belts 3 for arranging crops and seeds for cultivation, enabling the multiple growth belts 3 distributed across the multi-layered frame structure of the main frame 1 to form a three-dimensional, multi-layered plant cultivation system. The plant cultivation system has a drive mechanism 4 on one axial side of the main frame 1 to drive the growth belts 3 axially. The drive mechanism 4 is arranged along the height of the main frame 1 to cover its multi-layered frame structure. The drive mechanism 4 is connected to the growth belts 3 of each layer, allowing it to drive the growth belts 3 at different layers within the main frame 1. This enables the drive mechanism 4 to drive the corresponding growth belts 3 according to the crop status and cultivation needs of each layer, thus achieving the sowing, cultivation, and harvesting processes. On the side of the main frame 1 away from the drive mechanism 4, the plant cultivation system has a sowing mechanism 2 for seeding the growth belts 3. The sowing mechanism 2 can achieve controlled sowing of crop seeds based on processes such as material distribution, transmission, screening, and planting to ensure sowing quality. The sowing mechanism 2 is arranged along the height of the main frame 1, allowing it to cover the growth belts 3 at different layers of the main frame 1. On the side of the main frame 1 closest to the sowing mechanism 2, the plant cultivation system has a harvesting mechanism 7 for removing mature crops from the growth belts 3. The harvesting mechanism 7 extends along the width of the main frame 1 and is arranged in multiple layers to cover the growth belts 3 at different layers. To ensure the functional applicability of the sowing mechanism 2 at each planting stage, the sowing mechanism 2 has a sowing position close to or in contact with the growth belt 3 and a restraint position far from the growth belt 3. That is, the sowing mechanism 2 can change its positional relationship with the growth belt 3 by moving relative to the main frame 1. Similarly, the harvesting mechanism 7 has a harvesting position close to or in contact with the growth belt 3 and a restraint position far from the growth belt 3. That is, the harvesting mechanism 7 can change its positional relationship with the growth belt 3 by moving relative to the main frame 1.

[0028] Based on the relative positions of planting equipment such as the sowing mechanism 2, the drive mechanism 4, and the harvesting mechanism 7, as well as the growth belt 3, the plant planting system of this application can divide the main frame 1 into a first zone 8 to a third zone 10 distributed along the axial direction according to function. For example, the first zone 8 is used to arrange the sowing mechanism 2 and the harvesting mechanism 7, the third zone 10 is used to arrange the drive mechanism 4, and the second zone 9 is used to arrange the growth belt 3. The first zone 8 to the third zone 10 are physically isolated based on the adjustable partition component 15 set on the main frame 1. The partition component 15 can form a functional space for aeroponic planting with each layer of the frame structure of the main frame 1. While ensuring that each layer of the functional space in the second zone 9 can maintain stable aeroponic cultivation parameters, it can also isolate the adverse effects of aeroponics on the planting equipment arranged in the first zone 8 and the third zone 10. When the growth belt 3 moves axially, the separating component 15 adjusts its arrangement range along the height and / or width direction of the main frame 1, so that the separating component 15 has a first position away from the growth belt 3 and a second position close to the growth belt 3 relative to the main frame 1. The separating component 15 in the first position will not constrain or interfere with the moving growth belt 3, while the separating component 15 in the second position can physically isolate the second zone 9. The second zone 9 is equipped with a spray unit 5 and a light unit 6 for providing nutrients to the crops. The spray unit 5 and the light unit 6 are arranged in layers on the main frame 1 to target crops arranged on different layers of the growth belt 3 on the main frame 1.

[0029] Preferably, based on the manufacturing practice of planting devices and crop cultivation conditions, to ensure that the plant planting system of this application has reasonable dimensions to meet the layout requirements in a plant factory and the growth needs of the crops, the main frame 1 of the plant planting system of this application can be set with an axial dimension of approximately 8-17m, preferably 10-15m, more preferably 12.5m; the width dimension of the main frame 1 is approximately 2-5m, preferably 2.5m; and the height dimension of the main frame 1 is approximately 3-5m, preferably 3.5m. The main frame 1 can be provided with 3-5 cultivation layers, preferably 4 layers; in particular, the effective growth surface size of the seeds can reach 12m in length and 1.8m in width.

[0030] To improve the compactness of the plant planting system of this application and increase the yield per unit area, during sowing, cultivation and harvesting, the movement range of the growth belt 3 used to arrange crops or crop seeds relative to the main frame 1 is limited to the arrangement range of the main frame 1. This avoids the need to arrange auxiliary structures around the main frame 1 to assist the growth belt 3 in moving in or out of the main frame 1, thereby saving planting space and reducing the workload of the planting process. Specifically, the growth belt 3 moves back and forth along the axial direction of the main frame 1 under the action of the drive mechanism 4. The growth belt 3 carries crops or crop seeds close to or away from the sowing mechanism 2 in a manner that rotates around the width direction of the main frame 1. This makes the growth belt 3 have a first part and a second part that can be used to arrange crops or crop seeds at intervals. The first part and the second part are deformable flat surfaces along the axial direction that can be used to arrange crops or crop seeds. The first part and the second part are connected at the ends based on the arc-shaped growth belt 3 and supported by roller structures set at both ends of the growth belt 3. This makes the growth belt 3 configured as a tracked structure that moves around the rollers. Generally, the first part is the part of the growth belt 3 that carries crop seeds or crops during the cultivation process and is located at the upper part of each layer of space of the main frame 1. The second part is the part located at the lower part of each layer of space of the main frame 1 during the cultivation process. This allows the growth belt 3 to carry crop seeds or crops and move around the main frame 1 in a circumferential direction based on the rotational movement of the first part and the second part around the rollers.

[0031] The direction in which the growing belt 3 moves axially away from the sowing mechanism 2 is defined as the sowing direction A, and the direction in which the growing belt 3 moves axially towards the harvesting mechanism 7 is defined as the harvesting direction B. When the growing belt 3 moves towards the sowing direction A, at least a portion of the structure of the sowing mechanism 2 arranges crop seeds onto the growing belt 3 in a manner that brings it close to or contacts the growing belt 3, so that the crop seeds can be controlled and planted onto the growing belt 3 based on the sowing mechanism 2. When the growing belt 3 moves towards the harvesting direction B, the harvesting mechanism 7 removes the crop carried on the growing belt 3 in a manner that brings at least a portion of its structure close to or contacts the growing belt 3. To facilitate the movement of the growing belt 3 at each growth stage and to facilitate intervention and maintenance, the growing belt 3 can also change its movement mode by adjusting the drive mechanism 4. For example, the first movement mode is when the growing belt 3 moves around the roller towards the sowing direction A, the second movement mode is when the growing belt 3 moves around the roller towards the harvesting direction B, the third movement mode is when the growing belt 3 remains stationary, and the fourth movement mode is when the growing belt 3 moves out or in from one side of the main frame 1 axially. The first motion mode of the growth belt 3 is suitable for the sowing process, allowing the growth belt 3 to interact with the sowing mechanism 2 by moving along the axial direction of the main frame 1. The second motion mode of the growth belt 3 is suitable for the harvesting process, allowing the growth belt 3 to interact with the harvesting mechanism 7 by moving along the axial direction of the main frame 1. The third motion mode of the growth belt 3 is suitable for the cultivation process, allowing a portion of the growth belt 3 to carry the crop for growth and cultivation in the second zone 9 of the main frame 1. The fourth motion mode of the growth belt 3 is suitable for intervention processes, such as maintenance of the growth belt 3, allowing the growth belt 3 to be moved out of or into the arrangement range of the main frame 1 from one side of the axial direction to leave operating space for convenient maintenance or intervention. Therefore, when the movement range of the growth belt 3 is limited to the arrangement range of the main frame 1 based on the first to third motion modes, the sowing mechanism 2, drive mechanism 4, and harvesting mechanism 7 of the plant cultivation system realize the sowing, cultivation, and harvesting processes of the crop. The growth belt 3 can also extend its movement range beyond the arrangement range of the main frame 1 based on the fourth motion mode, allowing the plant cultivation system to be intervened or maintained based on the harvesting mechanism 7, external structures, or manual intervention.

[0032] like Figure 3As shown, the sowing mechanism 2 is equipped with a distribution component 11 for distributing crop seeds to each layer of the growth belt 3. The crop seeds are transferred to the screening components 13 arranged on each layer of the main frame 1 via a transmission component 12 connected to the distribution component 11. After being processed by the screening components 13, the crop seeds are evenly and controllably distributed onto the surface of the growth belt 3 via the sowing component 14. In the selection of high-quality seeds, high-quality seeds are a prerequisite for good and strong seedlings of crops such as forage grasses. They should meet the following conditions: high purity, plump and uniform grains, moderate moisture content, strong viability, and freedom from pests and diseases. Commonly used quantitative evaluation indicators include purity, thousand-grain weight, moisture content, germination rate, germination potential, and seed value. For example, suitable seed moisture content is crucial to seed viability, lifespan, storage, transportation, and trade. If the moisture content is too high, the seeds are prone to mold and deterioration during storage, and their viability is lost quickly. It also increases the burden of transportation and can sometimes become a trade obstacle. However, if the moisture content is too low, such as below 6%, it will also damage the seed viability. Generally, the moisture content of leguminous forage seeds is required to be 12% to 14%, and the moisture content of grass forage seeds is required to be 11% to 12%.

[0033] To achieve the integrated operation of intelligent sowing, automatic cultivation, and automatic harvesting in the plant planting system of this application, such as Figure 4 As shown, the plant cultivation system of this application is equipped with a processor 16 for automatic control or controlled adjustment. The processor 16 can automatically control and adjust the crop sowing, cultivation, and harvesting processes based on the planting equipment status information and crop seed status information obtained by the sensing unit 20, combined with the externally input cultivation plan and set parameters. Specifically, the processor 16 controls the spraying unit 5 and the lighting unit 6 based on the nutrient unit 17 to implement the nutrient plan for the crop cultivation process. That is, the nutrient unit 17 automatically controls the spraying unit 5 to spray water mist and controls the lighting unit 6 to provide the light required for seed growth and development, so that the spraying unit 5 and the lighting unit 6 can provide periodically changing spraying parameters and lighting parameters according to the crop cultivation cycle. The spraying parameters of the spraying unit 5 and the lighting parameters of the lighting unit 6 can also be adjusted specifically according to the crop harvesting status to improve crop production efficiency and quality. The processor 16 controls the relative movement of the drive mechanism 4 and the growth belt 3 based on the movement unit 18, so that the movement unit 18 can control the movement speed and movement mode of the growth belt 3. The processor 16 controls the sowing mechanism 2 based on the sowing unit 19 to sow crop seeds evenly and in a controlled manner onto the growth belt 3, enabling the sowing unit 19 to control and adjust the parameters of the sowing mechanism 2 related to distribution, transport, screening, and sowing. The processor 16 can also control the relative position of the separator component 15 on the main frame 1 relative to the growth belt 3 according to the movement pattern of the growth belt 3 to change the isolation state of the first zone 8 to the third zone 10 during sowing, cultivation, harvesting, and intervention.

[0034] Preferably, the plant planting system of this application is configured with several operating modes according to the crop growth stage. These operating modes are determined based on different crop growth states and different movement modes of the growth belt 3, enabling the plant planting system to achieve integrated intelligent sowing, automatic cultivation, and automatic harvesting throughout the entire process by alternating the use of these operating modes. Specifically, the crop growth states include, but are not limited to, the seed stage, the cultivation stage, and the maturity stage, and the movement modes of the growth belt 3 include, but are not limited to, the first to the fourth movement modes. The plant cultivation system of this application includes several operating modes: a first operating mode for the sowing process, where the crop is in the seed stage and the growth belt 3 uses the first movement mode; a second operating mode for the cultivation process, where the crop is in the cultivation period, i.e., the crop is in the transitional state from the seed stage to the maturity stage, and the growth belt 3 uses the third movement mode; a third operating mode for the harvest process, where the crop is in the maturity stage and the growth belt 3 uses the second movement mode; and a fourth operating mode for intervention and maintenance, where the crop is in one of the seed stage, cultivation stage, or maturity stage, or the growth belt 3 is in a blank period without crop or crop seeds, and the growth belt 3 uses the fourth movement mode, so that the growth belt 3 can be moved out of the arrangement range of the main frame 1 to expand the operating space for intervention on the growth belt 3 or the crop.

[0035] Preferably, when the plant cultivation system of this application is in the first operating mode, the processor 16 obtains the preparation status of the sowing mechanism 2 based on the sensing unit 20. In response to the signal indicating that the sowing mechanism 2 has completed its self-check, the processor 16 controls the drive mechanism 4 to activate the growth belt 3 in the first motion mode and maintain the sowing speed set in the cultivation plan based on the drive unit. In response to the signal indicating that the sowing mechanism 2 has completed its preparation, the processor 16 controls at least a portion of the structure of the sowing mechanism 2 to move from a constrained position away from the growth belt 3 to a sowing position close to or in contact with the growth belt 3 based on the sowing unit 19, so that the sowing mechanism 2 can arrange crop seeds on the growth belt 3 under controlled sowing parameters. The controlled sowing parameters relate to the distribution, transport, screening, and sowing process of the sowing mechanism 2, and may include distribution flow rate, transport speed, screening wind force, sowing flow rate, output speed, output interval, and the row and column parameters and density parameters of the crop seeds on the growth belt 3, etc. In response to a signal acquired by the sensing unit 20 indicating that the arrangement parameters and / or density parameters of crop seeds sown on the surface of the growth belt 3 do not match the range of parameters set in the cultivation plan, the processor 16 controls the sowing mechanism 2 based on the sowing unit 19 to adjust the sowing parameters, so that the row and column parameters and / or density parameters of the crop seeds on the growth belt 3 return to the range of parameters set in the cultivation plan. The growth belt 3 is configured with a targeted cultivation plan and a sowing speed for different crop seeds. The sowing speed is mainly determined based on the flow efficiency of the crop seeds on the sowing mechanism 2 and the stability of the crop seeds when they are arranged on the surface of the growth belt 3, so that the sowing speed set in the cultivation plan can match the sowing speed of the sowing mechanism 2 to ensure sowing efficiency, and can also control the secondary movement of the crop seeds on the growth belt 3 to ensure sowing accuracy.

[0036] Preferably, in the first operating mode, the processor 16 controls the sowing mechanism 2 based on the sowing unit 19 to adjust the sowing parameters by changing the output speed and interval of the crop seeds by the sowing component 14. The output interval of the crop seeds is changed in a manner that correlates the output interval with the movement speed of the growth belt 3 to conform to the parameter range set in the cultivation program. The output speed of the crop seeds is changed by controlling the magnitude and direction deviation of the movement speed of the crop seeds when they contact the growth belt 3 relative to the movement speed of the growth belt 3. The adjustment of the output interval and output speed of the crop seeds by the sowing structure 14 can be achieved through the structural settings and control devices of the sowing structure 14, such as controlling the output interval by roller rotation and controlling the output speed by the angle and length of the slide.

[0037] To avoid interference with the growth belt 3 during the sowing process, for example, the sowing component 14 in the sowing mechanism 2, used for seed output and release, must not damage the culture medium or surface structure of the growth belt 3. Therefore, in the first operating mode, there is a certain height difference between the sowing component 14 and the growth belt 3. This results in factors affecting the sowing quality during the process of crop seeds being output from the sowing component 14 and placed onto the growth belt 3, such as air resistance, velocity distribution, and the secondary motion of the crop seeds on the growth belt 3. The height difference between the sowing component 14 and the growth belt 3 causes the crop seeds to have a vertically downward velocity component, which, combined with the initial horizontal output velocity of the sowing component 14, forms the velocity of the crop seeds when they contact the growth belt 3. However, air resistance reduces the output velocity. Especially for crop seeds of different sizes or shapes, the uneven resistance of air resistance to the crop seeds changes the direction of the output velocity, causing a deviation in both magnitude and direction between the velocity of the crop seeds when they contact the growth belt 3 and the velocity of the growth belt 3. Size deviations can cause relative velocities in the vertical and horizontal directions when crop seeds come into contact with the growth belt 3, significantly increasing the probability of secondary motion of crop seeds relative to the growth belt 3. Meanwhile, directional deviations can disrupt the arrangement of crop seeds on the growth belt 3, causing deviations in the row and column parameters and / or density parameters of the seeds on the growth belt 3 from the range of parameters set in the cultivation program.

[0038] Therefore, to ensure that the row and / or density parameters of the crop seeds arranged on the growth belt 3 conform to the range set in the cultivation program, the key control points are: First, the coordination between the output interval of the planting component 14 and the set row and / or density parameters, that is, the correlation between the output interval of the planting component 14 and the movement speed of the growth belt 3 to adjust the arrangement interval parameters of the crop seeds on the growth belt 3 to control the set range of the row and / or density parameters. Second, the coordination between the output speed of the planting component 14 and the movement speed of the growth belt 3, including coordination in magnitude and direction; that is, minimizing the magnitude of the relative velocity generated when the crop seeds contact the growth belt 3 and adjusting the movement direction of the crop seeds when they contact the growth belt 3 to be close to the horizontal direction, thereby reducing the deviation of the actual row and / or density parameters from the set range.

[0039] Preferably, to adapt to the sowing process of different types of crop seeds, the sowing component 14 classifies crop seeds into several categories based on at least one of shape, size, and weight, and configures these categories in association with the sowing parameters of the sowing component 14 and the movement speed of the growth belt 3. This association configuration is achieved by differentiating the movement speed of the growth belt 3 according to the type of crop seed and coordinating it with the output speed and / or output interval of the sowing component 14. Since crop seeds have different sizes or shapes, to ensure that the arrangement of different types of crop seeds on the growth belt 3 conforms to the parameter range set in the cultivation program, the shape, size, and weight of the crop seeds should be classified, allowing the sowing component 14 and the growth belt 3 to be configured specifically to improve sowing quality. For example, spherical crop seeds roll well and experience relatively uniform air resistance, while kidney-shaped seeds roll poorly and experience uneven air resistance. When crop seeds contact the growth belt 3, stronger rolling ability means that even a small relative speed deviation can lead to larger deviations in row / column or density parameters. For irregularly shaped crop seeds, the uneven air resistance can cause deviations in their movement direction, causing them to deviate from the initial output speed of the seeding component 14, thus affecting the row / column or density parameters of the crop seeds on the growth belt 3. Therefore, for crop seeds with strong rolling ability and significant air resistance, the movement speed of the growth belt 3 should be appropriately reduced. This ensures that the output speed of the synchronously descending seeding component 14 minimizes air resistance and reduces deviations caused by secondary movement, thereby guaranteeing that the row / column or density parameters of the crop seeds on the growth belt 3 meet the parameter range set in the cultivation program. For example, crop seeds are classified into five categories based on their shape and weight density. The density gradually decreases from category one to category five, and the shape changes from round to crescent-shaped, making the density of the seeds in categories one through five lighter and their shape less circular. Category one crop seeds, due to their density and shape, will have greater rolling inertia, resulting in a smaller relative velocity but also a larger relative displacement. Therefore, the movement speed of the growth belt 3 can be set at a lower level. Category five crop seeds, due to their shape and density, will experience greater air resistance. A higher output speed will affect the magnitude and direction of the speed at which the crop seeds move from the planting component 14 to the growth belt 3. Therefore, the movement speed of the growth belt 3 also needs to be set at a lower level. Thus, the movement speeds of the growth belt 3 for categories one through five are set to 40%-60%V, 60%-80%V, 80%-100%V, 60%-80%V, and 40%-60%V, respectively, where V is the maximum set speed for the growth belt.To ensure that the row and column parameters or density parameters of crop seeds on the growth belt 3 meet the parameter range set in the cultivation program and to reduce the speed deviation when crop seeds contact the growth belt 3, the greater the movement speed of the growth belt 3, the smaller the output interval of the planting component 14 and the greater the output speed. That is, the output interval of the planting component 14 is inversely proportional to the movement speed of the growth belt 3, and the output speed of the planting component 14 is directly proportional to the movement speed of the growth belt 3. Considering the influence of shape on movement speed and movement time, the output speed and output interval of crop seeds of categories one to five are adjusted by superimposed adjustment. This allows the output speed and output interval of the planting component 14 to be controlled in real time according to the deviation of the row and column parameters or density parameters of crop seeds on the growth belt 3 from the set parameter range of the cultivation plan. This enables the proportion of crop seeds arranged on the growth belt 3 that conforms to the set parameter range of the cultivation plan to be increased by at least 15 percentage points. In particular, for irregularly shaped crop seeds, this proportion can be increased by at least 20 percentage points. This can effectively improve the uniformity and accuracy of crop seeds arranged on the growth belt 3, thereby providing a reasonable spatial layout for the growth and cultivation process of crop seeds on the growth belt 3 to improve cultivation efficiency and cultivation quality.

[0040] In the first mode, processor 16 controls the spraying unit 5 to pause operation based on the nutrient unit 17, while the illumination unit 6 retains illumination light for the sensing unit 20. This allows the sensing unit 20 to obtain image information showing the row and column parameters and density parameters of crop seeds on the growth belt 3 based on the camera installed in the main frame 1. Processor 16 controls the separating component 15 to be in a first position relative to the main frame 1, ensuring that the growth belt 3 and the crop seeds carried on it are not interfered with by the separating component 15. Processor 16 controls the harvesting mechanism 7 to remain in a restricted position away from the growth belt 3 based on the harvesting unit 21.

[0041] Preferably, in response to the sensing unit 20 acquiring a signal that the growth belt 3 has moved to the end of the main frame 1 away from the sowing mechanism 2 in the first operating mode, the plant planting system of this application switches from the first operating mode to the second operating mode. That is, when the crop seed sowing process is completed in the first or second part of the growth belt 3 and the second area 9 of the main frame 1 is covered, the sowing process is completed and the system is ready to enter the cultivation process.

The processor 16 controls the spray unit 5 and the light unit 6 based on the nutrient unit 17 to provide periodic aerosol parameters and light parameters based on the cultivation program to the crop seeds on the growth belt 3. The spray parameters of the spray unit 5 and the light parameters of the light unit 6 can also be adjusted in a targeted manner according to the crop harvest status to improve crop production efficiency and production quality.

[0042] Preferably, in response to the sensing unit 20 acquiring a signal that the crop on the growth belt 3 has reached maturity from the cultivation period, the plant cultivation system of this application switches from the second operating mode to the third operating mode, that is, the crop arranged on the first or second part of the growth belt 3 has reached a harvestable maturity state, the cultivation process is completed, and it is ready to enter the harvest process. When the plant cultivation system of this application is in the third operating mode, the processor 16 controls the separating component 15 to change from a second position close to or in contact with the growth belt 3 to a first position far away from the growth belt 3, so that the separating component 15 will not interfere with the growth belt 3 or the crop on the growth belt 3. The processor 16 controls the spraying unit 5 to stop using based on the nutrient unit 17, while the lighting unit 6 retains the illumination light for the sensing unit 20. The processor 16 changes the harvesting mechanism 7 from a restricted position far away from the growth belt 3 to a harvesting position close to the growth belt 3 based on the harvesting unit 21. The processor 16 controls the drive mechanism 4 based on the moving unit 18 to change the movement mode of the growth belt 3 from the third movement mode to the second movement mode, so that the growth belt 3 carrying the crop moves in the harvesting direction B at the harvesting speed set by the cultivation scheme.

[0043] Preferably, in response to a signal indicating that the planting equipment is in a faulty state and / or that the crop is in an abnormal state, the plant planting system of this application changes its operating mode to a fourth operating mode. A faulty planting equipment state refers to a state where the planting equipment, such as the sowing mechanism 2, harvesting mechanism 7, or growth belt 3, is uncontrollable or where parameter information obtained by the sensing unit 20 exceeds its normal operating range. An abnormal crop state refers to a state where crop parameters or crop images obtained by the sensing unit 20 exceed a predetermined range or where the nutrient unit 17 has failed to intervene, indicating a diseased state. The processor 16 controls the sowing mechanism 2 to stop sowing and change or maintain a constrained position away from the growth belt 3 based on the sowing unit 19; the processor 16 controls the harvesting mechanism 7 to change or maintain a restricted position away from the growth belt 3; the processor 16 controls the separating component 15 to change or maintain a first position away from the growth belt 3; the processor 16 controls the spraying unit 5 to suspend operation based on the nutrient unit 17, while the lighting unit 6 retains illumination light for the sensing unit 20. The processor 16 controls the drive mechanism 4 based on the moving unit 18 to change the motion mode of the growth belt 3 to the fourth motion mode, so that the growth belt 3 moves out of or into the arrangement range of the main frame 1 from one side of the axis of the main frame 1, so that the growth belt 3 that moves out of the main frame 1 can obtain an operating space that is convenient for intervention and maintenance, and moves back into the arrangement range of the main frame 1 after the intervention or maintenance is completed.

[0044] Preferably, the components of the sensing unit 20 used to collect status information of the planting equipment and crops include, but are not limited to, several temperature sensors, humidity sensors, light intensity sensors, and gas concentration sensors. The sensing unit 20 can be connected to image sensors, temperature sensors, humidity sensors, light intensity sensors, and gas concentration sensors to acquire status information of the plant planting system.
