Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of the embodiments of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] According to the present invention, a DFT floating hydroponic system is provided, such as... Figures 1 to 13 As shown, the DFT floating hydroponic system is used for soilless cultivation of crops. The DFT floating hydroponic system includes a hydroponic tank 1, a conveyor line, a planting mechanism 401, and a harvesting mechanism 402.

[0037] In the following description, reference will be made to Figures 1 to 13 This section describes the detailed structure of the hydroponic tank 1, conveyor line, planting mechanism 401, and harvesting mechanism 402 of the DFT floating hydroponic system. Additionally, as... Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the embodiment also involves three directions: a first direction S1, a second direction S2, and a third direction S3. The first direction S1 can be understood as... Figure 1 The direction from one end to the other on the long side of the DFT floating hydroponic system, the second direction S2 can be understood as... Figure 1 The direction from one end to the other on the short side of the DFT floating hydroponic system in the text, the third direction can be understood as the direction extending from the bottom of the hydroponic pool 1 towards the top, the first direction S1, the second direction S2 and the third direction S3 can be perpendicular to each other.

[0038] like Figures 1 to 3 As shown, in this embodiment, the hydroponic tank 1 contains nutrient solution and is used to place the floating plate 7, while also supporting the growth of crops planted on the floating plate 7. A conveyor line is used for transporting the floating plate 7. To automate the hydroponic system, the floating plate 7 can be transported to the designated hydroponic tank 1 via the conveyor line. A planting mechanism 401 and a harvesting mechanism 402 are respectively located at both ends of the hydroponic tank 1. The floating plate 7, transported to the designated end of the hydroponic tank 1 via the conveyor line, can be placed in the hydroponic tank 1 by the planting mechanism 401 for hydroponics. After the crops have grown, the floating plate 7 can be transferred from the hydroponic tank 1 to the conveyor line by the harvesting mechanism 402 for harvesting.

[0039] Specifically, both the planting mechanism 401 and the harvesting mechanism 402 include transfer forks, which can cooperate with the floating plate 7. When the floating plate 7 is transported to the planting mechanism 401 via the conveyor line, the planting mechanism 401 uses the transfer forks to lift the floating plate 7 set on the conveyor line and transfer the floating plate 7 to the hydroponic tank 1. The transfer forks of the harvesting mechanism 402 lift the floating plate 7 located in the hydroponic tank 1 and transfer the floating plate 7 to the conveyor line.

[0040] Furthermore, the conveyor line includes a transplanting conveyor section 301, a planting conveyor section 302, a harvesting conveyor section 303, and a processing conveyor section 304. The transplanting conveyor section 301 plants crops onto the floating plate 7. The specific operation is as follows: a transplanting machine (which can be any existing equipment, the structure and operation of which are known to those skilled in the art and will not be described in detail here) places planting cups from seedling trays onto the transplanting conveyor section 301 in batches. The transplanting machine then places the planting cups from the seedling trays onto the floating plate 7, completing the planting of seedlings on one floating plate 7. The planting conveyor section 302 transports the planted floating plate 7 to below the planting mechanism 401. The harvesting conveyor section 303 accepts the grown floating plates 7 harvested from the hydroponic pond 1 by the harvesting mechanism 402 and transports the floating plates 7 to the processing conveyor section 304. The processing and conveying unit 304 can perform root cutting of the grown crops (using the root cutting mechanism described below). After the root cutting is completed, the workers harvest the crops on the floating board 7, and after the mature crops are harvested, they are packed into packaging boxes via a workbench. The floating board 7 after harvesting is conveyed by the processing and conveying unit 304 to the washing machine (the washing machine can be equipment in the prior art, the structure and working process of which are known to those skilled in the art and will not be described in detail here). The washing machine cleans the floating board 7, and the workers stack the cleaned floating boards 7 together in sequence for the next seedling planting.

[0041] The planting and conveying unit 302 and the harvesting and conveying unit 303 are respectively located at both ends of the hydroponic pool 1. The planting mechanism 401 and the harvesting mechanism 402 are respectively located at the planting and conveying unit 302 and the harvesting and conveying unit 303. The transplanting and conveying unit 301 is connected to the planting and conveying unit 302 to transport the transplanted floating board 7 to one end of the hydroponic pool 1. The planting mechanism 401 puts the transplanted floating board 7 into the hydroponic pool 1 through the transfer fork. The grown floating board 7 is transported to the harvesting and conveying unit 303 through the transfer fork of the harvesting mechanism 402. The harvesting and conveying unit 303 is connected to the processing and conveying unit 304 to transport the grown floating board 7 to the processing and conveying unit 304 for processing.

[0042] This DFT floating hydroponic system, through the coordination of hydroponic tank 1, conveyor line, planting mechanism 401, and harvesting mechanism 402, enables automated soilless cultivation of crops. The conveyor line surrounding the hydroponic tank 1 facilitates automated planting, transportation of the floating plate 7, and post-crop transportation. The conveyor line, including transplanting conveyor 301, planting conveyor 302, harvesting conveyor 303, and processing conveyor 304, enables modular production of soilless cultivation. Manual operation is only required in the transplanting conveyor 301 and processing conveyor 304, thus achieving automated production and reducing the number of workers. The planting mechanism 401 and harvesting mechanism 402 automate both the planting and harvesting stages of the hydroponic tank 1, solving the problem of low efficiency in manual processing. This DFT floating hydroponic system has a compact overall structure, a simple production process, and a high degree of automation. It requires minimal human intervention for large-scale hydroponic cultivation, has high overall space utilization, and can achieve soilless cultivation in various scenarios.

[0043] Preferably, such as Figures 1 to 4 As shown, in this embodiment, there are multiple hydroponic ponds 1, arranged sequentially along the first direction S1. Each hydroponic pond 1 can hold multiple floating boards 7, thus achieving large-scale hydroponic cultivation. A planting conveyor 302 and a harvesting conveyor 303 are respectively located at both ends of the multiple hydroponic ponds 1. Both the planting conveyor 302 and the harvesting conveyor 303 can extend along the first direction S1, so that each hydroponic pond 1 has conveyor lines for the planting conveyor 302 and the harvesting conveyor 303 at both ends. A planting mechanism 401 and a harvesting mechanism 402 are movably disposed on the planting conveyor 302 and the harvesting conveyor 303, respectively. In order to make the overall system structure compact and easy to operate, the number of planting mechanism 401 and harvesting mechanism 402 is one. In order for the single planting mechanism 401 and harvesting mechanism 402 to correspond to multiple hydroponic ponds 1, the planting mechanism 401 and harvesting mechanism 402 need to be movably set in the planting conveying section 302 and the harvesting conveying section 303, respectively. The movability can be achieved by using a track and rollers.

[0044] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the hydroponic tank 1 can be formed as a cuboid structure, with a receiving trough inside the cuboid structure. The receiving trough is formed by multiple cuboid plates connected end to end to each other, and a waterproof cloth is laid inside the receiving trough to prevent leakage.

[0045] Preferably, such as Figures 4 to 8As shown, in this embodiment, the planting mechanism 401 and the harvesting mechanism 402 further include a frame section and a shifting section. The frame section includes a fixed frame 403 and a movable frame 404. The shifting section may include a first shifting component 405 and a second shifting component 406. The movable frame 404 is movably mounted on the fixed frame 403 in a second direction S2 via the first shifting component 405. The fixed frame 403 covers the planting conveyor section 302 or the harvesting conveyor section 303. The transfer fork is movably mounted on the movable frame 404 in a third direction S3 via the second shifting component 406. Both the first shifting component 405 and the second shifting component 406 can be formed as belt-driven structures, i.e., including a drive motor, a belt, a rotating wheel, and a moving block fixed on the belt. Figures 5 to 7 In the first displacement component 405, rotating wheels are provided at both ends in the second direction S2. A drive motor is connected to one of the rotating wheels, and a belt surrounds the two rotating wheels. The moving frame 404 is fixedly connected to the moving block. The drive motor drives the rotating wheels, which in turn drives the belt to move the moving block, thereby moving the moving frame 404 in the second direction S2. The moving frame 404 can move closer to or further away from the hydroponic tank 1 in the second direction S2. Figure 8 In this process, the structure of the second shifting component 406 is the same as that of the first shifting component 405. The difference is that the setting direction of the second shifting component 406 is perpendicular to the setting direction of the first shifting component 405, so that the transfer fork can move in the third direction S3. The transfer fork can move in the third direction S3 to place the floating plate 7 in the hydroponic tank 1 or lift the floating plate 7 out of the hydroponic tank 1.

[0046] Preferably, such as Figure 7 and Figure 9 As shown, in this embodiment, the second shifting component 406 includes a fixed rod 417. The end of the fixed rod 417 is connected to the moving block of the second shifting component 406. To ensure stable movement, two second shifting components 406 can be provided at both ends of the fixed rod 417. All components of the transfer fork can be provided on the fixed rod 417. The transfer fork can include a rotating component 407, a fork component 408, and a driving component 409. The end of the driving component 409 is provided on the fixed rod 417. The driving component 409 can be, for example, a rotary motor. The drive rod of the rotary motor is connected to the rotating component 407, and the end of the rotating component 407 is connected to the fork component 408. In addition, in order to stably support the floating plate 7, the transfer fork can include multiple sets of rotating components 407, fork components 408, and driving components 409. Multiple fork components 408 are driven simultaneously by a transmission rod. This transmission rod can be connected to a rotary motor and moves with the first rotating component 407, thereby driving the remaining rotating components 407 to rotate.

[0047] Preferably, such as Figure 5 and Figure 6 As shown, in this embodiment, the planting mechanism 401 and the harvesting mechanism 402 may further include a track assembly. The track assembly includes a slide rail 410 and track wheels 411 disposed at the bottom of a fixed frame 403. The fixed frame 403 is slidably mounted on the slide rail 410 via the track wheels 411. The slide rail 410 is disposed on the side of either the planting conveyor section 302 or the harvesting conveyor section 303. To ensure stable movement, the track assembly may consist of two parallel L-shaped slide rails 410 and four track wheels 411, with the four track wheels 411 respectively disposed at the four corners of the bottom of the fixed frame 403. To achieve automated drive, each track wheel 411 is equipped with a separate drive motor to drive the track wheel 411.

[0048] Thus, as Figure 5 As shown, the planting mechanism 401 and the harvesting mechanism 402 can include movement in four directions: First, the frame as a whole reciprocates in the S1 direction, so that one planting mechanism 401 or one harvesting mechanism 402 can correspond to multiple hydroponic ponds 1, realizing multi-purpose use of one machine; Second, the moving frame 404 reciprocates relative to the fixed frame 403 in the second direction S2. This movement in the second direction can make the transfer fork lift the floating plate 7 on the linear conveying mechanism 412 and transport it to the hydroponic pond 1, or lift the floating plate 7 from the hydroponic pond 1 and transfer the floating plate 7 to the linear conveying mechanism 412; Third, the transfer fork reciprocates in the third direction S3, so that the fork member 408 moves closer to or towards the floating plate 7 in the height direction. Fourth, the self-rotation of the fork member 408: the fork member 408 can cooperate with the following limiting connection block 101 and place the floating plate 7 in a certain position in the hydroponic tank 1. When the fork member 408 is moved or not used, it can be rotated and retracted by the drive member 409.

[0049] Preferably, such as Figure 2 As shown, in this embodiment, the transplanting conveying unit 301, the planting conveying unit 302, the harvesting conveying unit 303, and the processing conveying unit 304 can all include linear conveying mechanisms 412. The number of linear conveying mechanisms 412 can be one or more, and these mechanisms are connected end-to-end. The floating board 7 is transported from one linear conveying mechanism 412 to another adjacent linear conveying mechanism 412. In the planting conveying unit 302 and the harvesting conveying unit 303, when multiple hydroponic ponds 1 are arranged sequentially along the first direction S1, one linear conveying mechanism 412 cannot meet the production needs of the multiple hydroponic ponds 1. Therefore, multiple linear conveying mechanisms 412 connected end-to-end are provided at both ends of the hydroponic pond 1. In the transplanting conveying unit 301 and the processing conveying unit 304, because the hydroponic pond 1 is relatively long, multiple linear conveying mechanisms 412 connected end-to-end are needed to meet the processing requirements of the floating board 7.

[0050] Preferably, such as Figure 10 and Figure 11 As shown, in this embodiment, the linear conveying mechanism 412 may include a support body, a belt assembly 415, and a pulley 416. The support body may include a first support portion 4141 and a second support portion 4142. The distance between the first support portion 4141 and the second support portion 4142 corresponds to the width of the floating plate 7, so that the floating plate 7 can correspond to the width of the support body. The belt assembly 415 and the pulley 416 are respectively disposed on the top of the first support portion 4141 and the top of the second support portion 4142. The floating plate 7 is slidably disposed on the belt assembly 415 and the pulley 416. The belt assembly 415 may also be formed as a belt-driven structure, including a drive motor, a belt, and a rotating wheel. The drive motor drives the rotating wheel to rotate, thereby driving the belt to rotate around the rotating wheel. The floating plate 7 contacts the belt, so that the floating plate 7 experiences frictional resistance and moves in accordance with the movement of the belt. There are multiple pulleys 416, which are spaced apart on the top of the second support portion 4142, and the multiple pulleys 416 correspond to the belt assembly 415.

[0051] Furthermore, a linear conveyor mechanism 412 includes a belt-driven structure. Thus, the multiple linear conveyor mechanisms 412 of the conveyor line are relatively independent of each other, allowing the motors of some linear conveyor mechanisms 412 that do not need to transport the floating plate 7 to remain stationary, thereby saving energy. Correspondingly, the linear conveyor mechanisms 412 in the stationary state need to be activated when the floating plate 7 needs to be transported. Therefore, a contact switch 418 is provided at the end of the belt assembly 415. The contact switch 418 is connected to the drive motor of the next adjacent linear conveyor mechanism 412. When the floating plate 7 is driven by the belt assembly 415 and transported from one end of the linear conveyor mechanism 412 to the end where the contact switch 418 is located, it can contact the contact switch 418, thereby triggering the next linear conveyor mechanism 412.

[0052] Preferably, such as Figures 1 to 3As shown, in this embodiment, the transplanting conveyor 301, planting conveyor 302, harvesting conveyor 303, and processing conveyor 304 are connected by a corner conveyor mechanism 413. The corner conveyor mechanism 413 includes a support body, a belt assembly 415, and a sliding wheel 416. The corner conveyor mechanism 413 also includes a rotating shaft and a moving wheel disposed at the bottom of the support body, with the rotating shaft and the moving wheel disposed opposite to each other at both ends of the support body. Since the hydroponic tank 1 is formed into an approximately rectangular structure, there is a corner when the conveyor line surrounds the hydroponic tank 1, requiring the corner conveyor mechanism 413 to achieve corner transportation. The structure of the corner conveyor mechanism 413 is the same as that of the linear conveyor mechanism 412, except for the bottom configuration. The bottom of the linear conveyor mechanism 412 is a fixed structure including support feet, while the bottom of the corner conveyor mechanism 413 includes a rotating shaft and a moving wheel. The rotating shaft is fixedly connected to the ground, allowing the corner conveyor mechanism 413 to rotate around the rotating shaft, and the moving wheel assists in the rotation of the corner conveyor mechanism 413. When a floating plate 7 needs to be driven by the corner conveyor mechanism 413 and transported on the conveyor line in different directions, the floating plate 7 is transported to the top of the corner conveyor mechanism 413 through the previous straight conveyor mechanism 412. At this time, the belt assembly 415 of the corner conveyor mechanism 413 stops working and the rotating shaft is driven by the rotary motor to rotate, thereby driving the corner conveyor mechanism 413 to rotate around the rotating shaft, realizing the change of position. When it rotates to dock with a straight conveyor mechanism 412 in another direction, the rotating shaft stops rotating, the belt assembly 415 moves, so that the floating plate 7 located on the corner conveyor mechanism 413 moves to the straight conveyor mechanism 412 in another direction.

[0053] Preferably, such as Figure 12 As shown, in this embodiment, the conveying mechanism of the processing conveying unit 304 further includes a root-cutting mechanism, which is disposed between the first support part 4141 and the second support part 4142. The root-cutting mechanism includes two root-cutting blades 6 facing each other, located at the bottom of the floating plate 7. The root-cutting blades 6 can be used to cut off the roots of the crop after it has grown and matured, so as to facilitate subsequent manual processing. The root-cutting mechanism can be additionally provided in a linear conveying mechanism 412. The user can place the root-cutting mechanism in a suitable linear conveying mechanism 412 according to needs, such as the length of the processing conveying unit 304. A drive motor can be provided at the lower part of the root-cutting mechanism to drive the root-cutting blades 6 to rotate.

[0054] Preferably, such as Figure 4As shown, in this embodiment, the hydroponic tank 1 may include multiple limiting connecting blocks 101 with internal components. These multiple limiting connecting blocks 101 are arranged sequentially and at intervals along the first direction S1. The interval between two adjacent limiting connecting blocks 101 corresponds to the size of the transfer fork to limit the transfer fork. Specifically, the transfer fork may include multiple fork members 408, and the interval between the multiple limiting connecting blocks 101 can limit the multiple fork members 408 to ensure stable support of the floating plate 7. To ensure that both the planting mechanism 401 and the harvesting mechanism 402 can stably support the floating plate 7, limiting connecting blocks 101 are provided at both ends of the hydroponic tank 1 near the planting conveying section 302 and the harvesting conveying section 303.

[0055] Preferably, such as Figure 13 As shown, in this embodiment, the floating plate 7 can be made of PVC material, thus making it lightweight, but its length is relatively long. The length of the floating plate 7 in the first direction S1 corresponds to the length of the hydroponic tank 1 in the first direction S1, and the length of the floating plate 7 in the first direction S1 is greater than the length of the linear conveyor mechanism 412 in the first direction S1. The longer floating plate 7 not only allows for the cultivation of multiple crops but also ensures stability during transportation, allowing one floating plate 7 to simultaneously contact two linear conveyor mechanisms 412 during transport.

[0056] Furthermore, the floating plate 7 has multiple planting holes 701 for planting. Each planting hole 701 can be used for planting one plant.

[0057] In addition, it should be noted that the connection methods between the drive motor, rotary motor, etc., mentioned above and their driven components are known to those skilled in the art, and may be, for example, key shaft connection or coupling connector; the specific connection relationship between two components not mentioned is also known to those skilled in the art, and is a common connection method in the field, so it will not be described in detail.

[0058] The working process of this DFT floating hydroponic system is as follows:

[0059] The first step is to place the crop (germinating in the planting cup, such as leafy vegetable seedlings) in a multi-hole seedling tray. The transplanter in the transplanting conveyor 301 places the planting cups in the seedling tray in batches on the transplanting conveyor 301. The transplanter works to place the planting cups in the seedling tray into the planting holes 701 of the floating plate 7, thus completing the seedling planting of a floating plate 7.

[0060] The second step involves transporting the floating board 7 to the work station of the planting mechanism 401 through the cooperation of the linear conveying mechanism 412 and the corner conveying mechanism 413 of the planting conveying unit 302. The planting mechanism 401 then works and performs planting. Specifically, the planting mechanism 401 uses a transfer fork to pick up the floating board 7 from the work station and place it into the hydroponic pool 1. The pool contains nutrient solution, and the leafy vegetable seedlings absorb the nutrient solution to grow. The floating boards 7 float on the surface of the hydroponic tank 1. A transplanting machine sorts and continuously transports the floating boards 7 (with seedling planting cups) to the planting mechanism 401. The planting mechanism 401 detects the arrival of a floating board 7 (detection methods can include sensors or position switches, which are common and will not be elaborated further), and then places them sequentially into the hydroponic tank 1. The floating boards 7 are arranged sequentially in the hydroponic tank 1 until it is completely filled. In this way, leafy vegetable seedlings are planted in batches into the hydroponic tank 1, and the leafy vegetables grow. It should be noted that since multiple floating boards 7 can be placed in one hydroponic tank 1, the placement of multiple floating boards 7 can be understood as follows: each subsequent floating board 7 pushes the previous floating board 7 as it enters the hydroponic tank 1, and so on, until the tank is completely filled.

[0061] The third step is that the harvesting mechanism 402 lifts the mature leafy vegetables (leafy vegetables on the floating plate 7) in the hydroponic tank 1 by means of the transfer fork, and lifts the floating plate 7 onto the linear conveying mechanism 412 of the transplanting and conveying unit 301.

[0062] In the fourth step, the floating plates 7 are transported to the processing conveyor 304 via the linear conveyor 412 and the corner conveyor 413. The root-cutting blade 6 in the processing conveyor 304 cuts the roots of the mature leafy vegetables. After cutting, the equipment stops working, and workers harvest the leafy vegetables from the floating plates 7. Once all the mature leafy vegetables are harvested, they are packed into boxes, and the floating plates 7 on the processing conveyor 304 are then transported to a washing machine to be cleaned. Finally, the workers stack the cleaned floating plates 7 together for the next planting of leafy vegetable seedlings. This cyclical planting and harvesting improves the efficiency of leafy vegetable cultivation.

[0063] This DFT floating hydroponic system, through the coordination of hydroponic tanks, conveyor lines, planting mechanisms, and harvesting mechanisms, enables automated soilless cultivation of crops. The conveyor lines surrounding the hydroponic tanks facilitate automated planting, floating plate transportation, and post-growth transport of crops. The conveyor lines, including transplanting, planting, harvesting, and processing conveyor sections, enable modular production of soilless crops. Human intervention is limited to the transplanting and processing sections, thus automating production and reducing manpower. The planting and harvesting mechanisms automate both the planting and harvesting stages in the hydroponic tanks, solving the problem of low efficiency from manual handling. The DFT floating hydroponic system features a compact structure, simple production process, and high degree of automation. It requires minimal human intervention for large-scale hydroponic cultivation, offers high space utilization, and can achieve soilless cultivation in various scenarios.
