Description

Technical Field

[0001] The present invention relates to the technical field of cultivation devices, and in particular to a cultivation device for developing native plants and a cultivation method thereof. Background Art

[0002] Plant cultivation, especially the development and large-scale planting of native plants, is an important part of modern agriculture and ecological restoration. In order to improve land utilization and production efficiency, various high-density and three-dimensional cultivation devices have emerged.

[0003] The plants on the lower layers of fixed multi-layer cultivation racks often face the problem of insufficient light and ventilation due to the obstruction of the upper layers, and their growth performance is prone to unevenness. In addition, the fixed layer spacing cannot meet the dynamic changes in the plants' space requirements as they grow from seedlings to mature plants. Although fixed A-shaped or tower-type cultivation racks further increase the spatial density through inclined or vertically arranged planting units, their structure is also non-adjustable, resulting in uneven light distribution on the sunny and shady sides, and it is relatively inconvenient to manage and maintain the plants inside. The rotary cultivation system rotates around the central axis to ensure that all plants receive uniform light and irrigation periodically. Although this system effectively solves the problem of uniform resource allocation, its mechanical structure is usually extremely complex, with high manufacturing costs and energy consumption. At the same time, it is bulky, making it difficult to flexibly adjust the shape or compress the space according to maintenance needs. Summary of the Invention

[0004] The purpose of the present invention is to provide a cultivation device with flexible structure, adjustable mode, adaptability to the full cycle of plant growth, and efficient space utilization.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a native plant development and cultivation device, comprising a base, a center frame fixedly provided at the center position of the top of the base, and a spray assembly installed on the center frame;

[0006] Cultivation racks are provided on both sides of the central frame and are slidably connected to the base. A moving assembly is installed inside the base to drive the cultivation racks to expand or retract relative to the central frame.

[0007] The inner wall of the cultivation rack is provided with two rotating plates by means of rotational connection, and several mounting frames are installed between the two rotating plates by means of universal hinges. A cultivation box is placed in the mounting frame, and a limiting component for limiting the rotation of the mounting frame is provided on the rotating plate. A locking component for locking the rotating plate is installed on the cultivation rack.

[0008] As a further description of the above technical solution: the spray assembly includes a spray head installed on a central frame, a water tank fixedly connected to the base is arranged below the central frame, and a water pump fixed on the top wall of the water tank is connected to the inner cavity of the water tank and the spray head through pipes.

[0009] As a further description of the above technical solution: the moving component includes a screw rod, which is rotatably installed in the inner cavity of the base, and opposite threads are provided at both ends of the screw rod, and sliders are provided on the corresponding threads. The top of the slider passes through the base and is fixedly connected to the cultivation frame, and a drive motor for driving the screw rod to rotate is provided on the side wall of the base.

[0010] As a further description of the above technical solution: the limiting component includes two parallel strip plates fixedly mounted on the side walls of the mounting frame, the side walls of the rotating plate are provided with positioning plates that cooperate with the strip plates, and both positioning plates are provided with inclined grooves.

[0011] As a further description of the above technical solution: a rotating rod that passes through the rotating plate and can rotate is provided between the two positioning plates, and a positioning block is fixedly connected to the rotating rod, and the positioning block is used to selectively connect or separate with the strip plate.

[0012] As a further description of the above technical solution: a limiting block is fixed to the other end of the rotating rod, and the limiting block is arranged between the two positioning plates and is used to selectively fit between the positioning plates or into the inclined groove.

[0013] As a further description of the above technical solution: the rotating plate is provided with a positioning structure for limiting the axial movement of the rotating rod, and the positioning structure includes a screw threaded through the rotating plate and a positioning bar cooperating with the screw.

[0014] As a further description of the above technical solution: the locking assembly includes three locking holes arranged on the cultivation frame, a socket is opened on the rotating plate, and the locking rod passes through the locking hole and the socket at the same time in a threaded manner.

[0015] The method for cultivating native plants comprises the following steps:

[0016] Loading plants: Place the cultivation box containing native plant seeds or seedlings and substrate into the installation frame;

[0017] Initial setting: Drive the moving component to fold the cultivation rack, turn the rotating plate to a vertical state, and complete the first form setting by locking the component;

[0018] Mode switching: According to the plant growth stage, unfold the cultivation rack, rotate and lock the rotating plate to the inclined or horizontal state respectively, and switch to the second or third state to achieve the installation frame in a stepped or horizontal arrangement;

[0019] Automatic leveling: During the rotation process, the mounting frame automatically adjusts to a horizontal state under the action of gravity through the universal hinge;

[0020] Locking position: operating the limiting component to fix the leveled mounting frame in the corresponding position to prevent shaking;

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. By providing a cultivation frame that can move relative to the central frame, as well as a rotating plate and locking assembly that can rotate within the cultivation frame, the device can flexibly switch between three different working modes: vertical folding, trapezoidal expansion, and horizontal expansion. This enables the device to accurately match the dynamic needs of native plants for space, light, and ventilation at different stages, such as the seedling stage, growth stage, and maturity stage. This one device has multiple uses, greatly improving the adaptability and application value of the device.

[0024] 2. When transporting or not in use, the device is switched to vertical folding mode, with the incubation racks on both sides close to the center rack. All incubators are arranged vertically, minimizing the footprint. This compact design facilitates storage and transportation, significantly improving space utilization efficiency.

[0025] 3. In the trapezoidal or horizontal expansion mode, the obstructions between the layers of the incubators are effectively eliminated, ensuring that all plants can obtain uniform and sufficient light and air circulation. The sprinkler assembly located on the center frame can provide uniform irrigation for all plants on both sides without dead angles, ensuring fair distribution of water and fertilizer resources.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 7 The present invention provides a technical solution: a cultivation device for developing native plants, including a base 10, a center frame 11 is fixed at the top center of the base 10, and cultivation frames 12 are symmetrically provided on both sides of the center frame 11. The cultivation frames 12 are slidably connected to the base 10 through a moving component arranged in the base 10 to realize the expansion and contraction of the cultivation frames 12 relative to the center frame 11.

[0037] Specifically, the base 10 provides stable support for the entire device, the central frame 11 is vertically fixed to the top center of the base 10, and a spray assembly for irrigation is installed on it. The two cultivation racks 12 are respectively located on the left and right sides of the central frame 11, and their bottoms are slidably connected to the base 10.

[0038] The entire device can switch between three states: a compact vertical state (first state), Figure 1 As shown; an expanded trapezoidal state (second form) is as follows Figure 4 As shown; a fully expanded horizontal state (third form), such as Figure 5 In order to ensure the stability and durability of the structure, the base 10, the center frame 11 and the cultivation frame 12 are made of high-strength stainless steel or aluminum alloy profiles, and the surface is treated with anti-corrosion.

[0039] Two rotating plates 13 are rotatably connected between the inner walls of each cultivation rack 12. Between the two rotating plates 13, several mounting frames 14 are rotatably connected by universal hinges. The universal hinge structure ensures that no matter what angle the rotating plates 13 are at, the mounting frames 14 can always automatically adjust to a horizontal state under the action of gravity.

[0040] The cultivation box 15 is placed on the mounting frame 14 and is used to accommodate native plants and cultivation substrates. The cultivation box 15 is made of lightweight, corrosion-resistant PP or ABS engineering plastics, and has several drainage holes at the bottom to prevent water accumulation in the substrate and facilitate the recycling of nutrient solution.

[0041] In order to fix the components in different forms, the cultivation frame 12 is equipped with a locking assembly for locking the angle of the rotating plate 13. At the same time, the rotating plate 13 is also provided with a limiting assembly for limiting the installation frame 14 from unnecessary rotation after leveling.

[0042] Furthermore, in order to drive the cultivation racks 12 on both sides to move synchronously, a moving component is arranged in the inner cavity of the base 10, and the moving component includes a screw rod 19, which is rotatably installed along the length direction of the base 10. The two ends of the screw rod 19 are respectively processed with threads with opposite rotation directions. A slider 20 is sleeved on each threaded segment, and the top of the slider 20 passes through the top wall of the base 10 and is fixedly connected to the bottom of the corresponding cultivation rack 12.

[0043] A drive motor 21 is installed on the side wall of the base 10, and its output shaft is connected to one end of the screw rod 19. When the drive motor 21 is working, it drives the screw rod 19 to rotate. Since the threads at both ends rotate in opposite directions, the two sliders 20 will move simultaneously, thereby driving the two cultivation racks 12 to synchronously approach or move away from the center rack 11.

[0044] As another optional embodiment, the moving component can also use two independent drive motors 21 to drive the cultivation racks 12 on both sides respectively, and synchronize the speed and direction of the two motors through a central controller to achieve synchronous movement.

[0045] Furthermore, the spray assembly is used to provide moisture for the plants in the cultivation box 15. The spray assembly includes a spray head 16, which is installed on the central frame 11. Below the central frame 11, a water tank 17 is fixedly provided on the base 10. A water pump 18 is fixedly installed on the top wall of the water tank 17. The water inlet of the water pump 18 is connected to the inside of the water tank 17 through a pipe, and its outlet is connected to the spray head 16 through another pipe branch. When the water pump 18 is started, the water or nutrient solution in the water tank 17 can be extracted and sprayed out in atomized form through the spray head 16 to achieve irrigation of the plants.

[0046] The sprinkler head 16 is an atomizing nozzle to save water and increase humidity. A liquid level sensor and a water quality sensor (such as an EC / pH sensor) are added to the water tank 17, and the data is fed back to the control system. At the same time, a filtering device can be set at the return water outlet of the water tank 17 to filter and recover the excess liquid discharged from the cultivation box 15, forming a circulating irrigation system to save water and fertilizer.

[0047] Furthermore, the device can also be installed with a lighting component, which includes several LED plant growth lamps. These growth lamps are installed on the side walls of the central frame 11, facing the cultivation frames 12 on both sides. The LED plant growth lamps are full-spectrum light sources that can simulate natural light to meet the needs of plant photosynthesis. The switching and lighting duration of the growth lamps are uniformly managed by the central control system described later.

[0048] Furthermore, the locking assembly is used to fix the rotating plate 13 at a specific angle. Specifically, three locking holes 121 are provided on the side wall of the cultivation rack 12. These three locking holes 121 correspond to three working modes of the cultivation device, namely vertical, trapezoidal and horizontal.

[0049] The rotating plate 13 is provided with a socket 133 aligned with the locking hole 121. The locking assembly also includes a locking rod 27. When the rotating plate 13 is rotated to a desired angle so that the socket 133 on the rotating plate 13 is aligned with the corresponding locking hole 121 on the center frame 11, the locking rod 27 is screwed into the locking hole 121 and the socket 133, thereby locking the rotating plate 13.

[0050] Furthermore, the limiting assembly is used to fix the mounting frame 14 after it is automatically leveled to prevent it from shaking during movement or irrigation.

[0051] Specifically, two parallel strip plates 141 are fixed on a side wall of the mounting frame 14 , and two positioning plates 131 are fixed on the side wall of the rotating plate 13 corresponding to the positions of the strip plates 141 , each positioning plate 131 having an inclined groove 132 .

[0052] A rotating rod 22 is provided between the two positioning plates 131. The rotating rod 22 passes through the rotating plate 13 and can rotate. A positioning block 23 is fixed to one end of the rotating rod 22 facing the mounting frame 14. When locking is required, the rotating rod 22 is operated, and the positioning block 23 will move and be stuck between the two strip plates 141, thereby limiting the rotation of the mounting frame 14.

[0053] A limiting block 26 is fixed to the other end of the rotating rod 22 , that is, the end located outside the rotating plate 13 . The shape of the limiting block 26 matches the gap between the two positioning plates 131 and the inclined groove 132 , and can be snapped into them.

[0054] like Figure 7As shown, in the vertical or horizontal state, the axial movement of the rotating rod 22 is achieved by pushing the limiting block 26, so that the positioning block 23 cooperates with the strip plate 141 to limit the rotation of the mounting frame 14. Due to the axial movement of the rotating rod 22, the limiting block 26 is simultaneously embedded in the gap between the two positioning plates 131, and under the action of the positioning plates 131, the rotating rod 22 is effectively prevented from rotating, and its axial movement is further limited by the positioning structure.

[0055] In the tilted state, the operation is similar to the above, except that the limiting block 26 is embedded in the tilted groove 132, and then the axial movement is also limited by the positioning structure.

[0056] Furthermore, in order to prevent the rotating rod 22 from axial movement when not in operation, a positioning structure is provided. The positioning structure includes a screw 24, which is threaded through the rotating plate 13. A positioning bar 25 is provided on the screw 24, and one end of the positioning bar 25 abuts against the surface of the limiting block 26.

[0057] By rotating the screw 24 , the contact force of the positioning bar 25 on the limiting block 26 can be adjusted, thereby effectively limiting the axial movement of the rotating rod 22 .

[0058] Furthermore, the automation function of the device is realized by a central control system, which includes a control box installed on the base 10 or the center frame 11, in which a microcontroller (MCU) or a programmable logic controller (PLC) is integrated; a user interaction interface, such as a touch screen or physical buttons, is provided on the outside of the control box. The central control system is electrically connected to the drive motor 21, the water pump 18, the lighting component and optional sensors (such as liquid level, water quality, soil moisture, temperature and humidity sensors, etc.). The user sets parameters such as the working mode, irrigation time, and light cycle through the interactive interface. The controller automatically performs all operations according to the preset program, realizing intelligent and unmanned management.

[0059] For example, the controller can automatically start the spray assembly based on the data from the soil moisture sensor, or automatically control the switch and duration of the LED growth light according to a set schedule. In order to facilitate mobility, several universal wheels with braking function can also be installed at the bottom of the base 10.

[0060] A method for cultivating native plants comprises the following steps:

[0061] Step 1: Place the prepared cultivation matrix and native plant seeds or seedlings into the cultivation box 15 , and place the cultivation box 15 on the mounting frame 14 .

[0062] Step 2: When not in use or when moisturizing and avoiding light are needed in the early stage of seedling cultivation, select the "folding" mode through the interface of the central control system. The controller drives the motor 21 to rotate in the opposite direction, so that the cultivation racks 12 on both sides are folded close to the center rack 11. At this time, release the locking assembly and the limiting assembly, adjust the rotating plate 13 to a vertical state, and lock it with the locking rod 27 in the corresponding first locking hole 121. All the cultivation boxes 15 will be arranged vertically due to the automatic leveling of the mounting frame 14. This form occupies the smallest area and is convenient for transportation and centralized management.

[0063] Step 3: When the plants enter the growth period and need sufficient light and ventilation, select "Growth Mode" through the control interface, and the controller starts the drive motor 21 to expand the cultivation rack 12 to both sides to the preset trapezoidal spacing. Then, pull out the locking rod 27, and manually rotate the rotating plates 13 on both sides outward to an inclined angle, so that the upper and lower cultivation boxes 15 form a stepped distribution to ensure that the plants in the lower layer can also obtain uniform light and ventilation. After the angle is determined, insert the locking rod 27 into the corresponding second locking hole 121 on the cultivation rack 12 and the socket 133 of the rotating plate 13 to lock it.

[0064] Subsequently, the various limiting components are operated to fix all the mounting frames 14 to prevent shaking. In this state, the automatic irrigation and lighting programs are set and started. The central control system will automatically start the sprinkler components for irrigation according to the set schedule or sensor data, and control the LED growth lights on the central frame 11 to provide the required light.

[0065] Step 4: For plants that require maximum light or are in the later stages of growth, select "full light mode" through the control interface, further unfold the cultivation rack 12, pull out the locking rod 27, and rotate the rotating plate 13 outward to a horizontal state. At this time, several installation frames 14 and cultivation boxes 15 on the same side are arranged linearly on the same horizontal line without blocking each other, maximizing the reception of natural light or artificial light. Similarly, use the locking rod 27 to lock it in the third locking hole 121, and operate the limiting component to fix all the installation frames 14.

[0066] Step 5: When the plants are mature, fold or unfold the device to a convenient position for harvesting.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
