Description

Technical Field

[0001] This invention relates to the field of agricultural technology, specifically to a seedling cultivation rack. Background Technology

[0002] The background technology of cultivation racks is rooted in the evolution of controlled-environment agriculture, aiming to artificially simulate and optimize plant growth conditions to overcome the seasonality, spatial limitations, and resource consumption problems of traditional agriculture. Its core stems from developments in three major areas: first, artificial environmental control technologies, such as the breakthrough application of high-efficiency LED light sources, coupled with precise temperature, humidity, CO2 concentration, and airflow management systems; second, the maturity of soilless cultivation methods, including hydroponics, aeroponics, and substrate culture, combined with automated nutrient solution monitoring and circulation systems; and third, interdisciplinary integration, such as sensor networks, IoT platforms, and materials science, providing a foundation for intelligent control. These technologies have collectively driven the transformation of cultivation racks from simple frameworks to highly automated, data-driven systems, supporting efficient and sustainable production in modern vertical agriculture and urban farms.

[0003] The existing cultivation trays are usually stationary. When placed indoors, the seedlings near the light source receive sufficient light, but the seedlings far from the light source do not receive enough light due to the obstruction of the cultivation rack itself. This results in uneven seedling growth, with some seedlings growing weakly or withering.

[0004] To address the above issues, a seedling cultivation rack is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a seedling cultivation rack. By using this device, the problem mentioned in the background is solved: the cultivation trays of existing seedling cultivation racks are usually stationary. When placed indoors, seedlings near the light source receive sufficient light, but seedlings far from the light source receive insufficient light due to the obstruction of the cultivation rack body. This results in uneven seedling growth, with some areas of seedlings growing weakly or withering.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A seedling cultivation rack is provided, comprising a cultivation rack assembly. A plurality of cultivation tray assemblies are rotatably connected within the cultivation rack assembly. Each of the cultivation tray assemblies is fixedly connected to a first synchronous pulley.

The two push-pull assemblies are rotatably connected to the two ends of a plurality of reflector assemblies. The plurality of reflector assemblies are arranged along the push-pull assemblies and are rotatably connected to the cultivation rack assembly.

[0007] Furthermore, the culture rack assembly includes a culture rack body, which is configured with several layers, and protective covers are fixedly connected to the left and right sides of the culture rack body.

[0008] Furthermore, each of the several culture tray assemblies includes a culture tray body, and the several culture tray bodies are evenly arranged in each layer of the culture rack body. The lower end of the several culture tray bodies is fixedly connected to one end of a rotating shaft, and the other end of the rotating shaft is rotatably connected to the culture rack body. A synchronous pulley is fixedly connected to the rotating shaft, and the synchronous pulleys on two adjacent rotating shafts are connected by a synchronous belt drive.

[0009] Furthermore, the drive assembly includes a motor, which is fixedly connected to the left side of the cultivation rack body. The motor is located within the working cavity formed by the protective cover and the cultivation rack body. The output end of the motor is fixedly connected to one end of the drive shaft. The drive shaft is fixedly connected to a second synchronous pulley. The other end of the drive shaft is fixedly connected to a first bevel gear. A transmission shaft is rotatably connected to the left side of the cultivation rack body. A second bevel gear is fixedly connected to the transmission shaft. The second bevel gear is disposed within the working cavity. The first bevel gear meshes with the second bevel gear. A first gear is also fixedly connected to the transmission shaft.

[0010] Furthermore, the clutch assembly includes a second gear, which is disposed in the working cavity on the left side of the culture rack body. The second gear is fixedly connected to one end of a slide rod, which is slidably connected to the protective cover on the left side of the culture rack body. The other end of the slide rod is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is fixedly connected to the output end of a cylinder. The cylinder is fixedly connected to the outside of the protective cover.

[0011] Furthermore, each of the aforementioned scattering components includes a reflector, which is fixedly connected to the culture rack body. A mounting plate is provided below the reflector, and a prism is fixedly connected to the mounting plate. A nut is fixedly connected to the mounting plate, and the nut engages with a lead screw via a thread. The lead screw is rotatably connected to the culture rack body, and a gear is fixedly connected to one end of the lead screw. A guide rod is fixedly connected to the culture rack body, and the mounting plate is slidably connected to the guide rod. Several vision cameras are fixedly connected to the culture rack body.

[0012] Furthermore, both of the push-pull assemblies include electric push rods, which are respectively disposed in the working cavities on the left and right sides of the culture rack body. One end of each electric push rod is rotatably connected to the side wall of the culture rack body, and the output end of each electric push rod is rotatably connected to the upper end of the push-pull rod.

[0013] Furthermore, both of the push-pull assemblies include two slide rails, which are fixedly connected to the inside of the protective cover. Both slide rails are arranged longitudinally in the working cavity. A slider is slidably connected to each of the two slide rails. The slider is slidably connected to the push-pull rod. One end of the slider is fixedly connected to a spring, and the other end of the spring is fixedly connected to the slide rail.

[0014] Furthermore, each of the several reflector assemblies includes a reflector body, the several reflector bodies are arranged longitudinally, and an angle adjustment shaft is fixedly connected to each of the several reflector bodies. The two ends of the angle adjustment shaft are respectively fixedly connected to one end of two deflection rods. The angle adjustment shaft is rotatably connected to the culture rack body, and the other end of the deflection rod is rotatably connected to a push-pull rod. A photodetector is fixedly connected to the culture rack body.

[0015] Furthermore, the reflector body is wavy, and one side of the reflector body is fixedly connected to the angle adjustment shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The synchronous wheel system driven by the drive component makes the cultivation tray assembly rotate at a low speed. The rotating shaft is driven by the synchronous belt, so that all the cultivation trays rotate continuously, ensuring that the seedlings move to the light-receiving point in turn. The low rotation speed and small centrifugal force avoid seedling damage, ensure uniform seedling light, improve cultivation quality, and reduce growth differences.

[0017] 2. The reflector assembly features a wave-shaped design with a gradually changing curvature that optimizes the reflection path. Through the push-pull assembly and photoelectric detector, the solar incidence angle is automatically monitored and the reflector angle is adjusted. The electric push rod pushes the deflection rod, causing the reflector body to deflect, maximizing the reflection of light to the seedling area. This efficiently reflects the light that would otherwise be directed to the ground to the cultivation area, improving the utilization rate of natural light.

[0018] 3. The scattering component includes a reflector and a prism, which move through a clutch assembly and a lead screw system. When the vision camera detects a potential difference area, the cylinder drives the gear system to move the prism to the target area for scattering and supplementing light. The light is scattered from the top down, covering the low-light seedling area. No additional lighting is required, making it energy-efficient.

[0019] 4. When there is no light, the reflector can be tilted upward to its maximum angle to close the open area of ​​the cultivation rack, reduce heat loss, maintain a stable temperature, and improve the survival rate of seedlings.

[0020] 5. The wave-shaped reflector and prism scattering system ensure that light covers the entire longitudinal plane. The spring and slide rail design of the push-pull assembly buffers the impact of movement, improves stability, has a compact and reliable structure, and provides more sufficient light coverage. Combined with the rotation of the cultivation tray, it enhances the overall cultivation effect. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figures 1-3 As shown, a seedling cultivation rack includes a cultivation rack assembly 1. A plurality of cultivation tray assemblies 2 are rotatably connected within the cultivation rack assembly 1. Each cultivation tray assembly 2 is fixedly connected to a first synchronous wheel 3. The first synchronous wheel 3 is connected to a second synchronous wheel 4 via a synchronous belt. The second synchronous wheel 4 is fixedly connected to a drive assembly 5. The drive assembly 5 is connected to the cultivation rack assembly 1. A clutch assembly 6 is also connected to the cultivation rack assembly 1. A plurality of scattering components 7 are also connected within the cultivation rack assembly 1. Two push-pull assemblies 8 are also connected to the cultivation rack assembly 1. The two push-pull assemblies 8 are rotatably connected to both ends of a plurality of reflector assemblies 9. The plurality of reflector assemblies 9 are arranged along the push-pull assemblies 8 and are rotatably connected to the cultivation rack assembly 1.

[0025] When cultivating plant seedlings, soil is sprinkled onto the cultivation tray assembly 2, and the seedlings are planted in the soil. Since this device is placed indoors where lighting is poor, it can be placed near a window or other well-lit location. Because some seedlings are blocked by the cultivation rack assembly 1, those far from the window do not receive light. Therefore, the drive assembly 5 can drive the synchronous pulley 4 to rotate, which in turn drives the synchronous pulley 3 via the synchronous belt, thus rotating several cultivation tray assemblies 2. The cultivation tray assemblies 2 rotate at a low speed, and the drive assembly 5 rotates continuously during the seedling cultivation stage. The centrifugal force generated by the rotation will not damage or displace the seedlings. Through the rotation of the cultivation tray assemblies 2, seedlings far from the light source can be moved to the light source to receive light. The seedlings cultivated by this device receive more uniform lighting, resulting in higher seedling cultivation quality. The device can adjust the angle between the reflector assembly 9 and the cultivation rack assembly 1 based on the changes in the incident angle of sunlight. This ensures that after sunlight shines on the reflector assembly 9, some light is reflected to the area where the seedlings are located, while the rest is reflected to the scattering assembly 7. The scattering assembly 7 then scatters the light downwards from the top of the plant. When it is detected that some seedlings are not growing well due to lack of light, the clutch assembly 6 closes. This causes the clutch assembly 6 to rotate along with the drive assembly 5. The rotation of the clutch assembly 6 transmits the rotational force to the scattering assembly 7, causing the scattering assembly 7 to move to the area where the seedlings are lacking light, scattering the light and covering that area to provide supplemental lighting.

[0026] Reference Figure 3 and Figure 4 As shown, the culture rack assembly 1 includes a culture rack body 11, which is arranged in several layers, and protective covers 12 are fixedly connected to both the left and right sides of the culture rack body 11.

[0027] Each of the several layers of the cultivation rack body 11 is equipped with a drive assembly 5, a clutch assembly 6, a scattering assembly 7, and a reflector assembly 9. Each of the several layers of the cultivation rack body 11 is equipped with a cultivation tray assembly 2. The rear end of the cultivation rack body 11 is open, allowing sunlight to shine in and illuminate the plant seedlings. Seedlings far from the open part of the cultivation rack body 11 are blocked by the cultivation rack body 11, resulting in poor lighting. In order to facilitate the demonstration of the technical solution, this invention only shows the first layer. In the actual manufacturing process, the arrangement of the first layer can be referred to.

[0028] Reference Figure 3 and Figure 6 As shown, each of the several culture tray assemblies 2 includes a culture tray body 21. The several culture tray bodies 21 are evenly arranged in each layer of the culture rack body 11. The lower end of the several culture tray bodies 21 is fixedly connected to one end of a rotating shaft 22. The other end of the rotating shaft 22 is rotatably connected to the culture rack body 11. A synchronous pulley 3 is fixedly connected to the rotating shaft 22. The synchronous pulleys 3 on two adjacent rotating shafts 22 are connected by a synchronous belt drive.

[0029] Soil is spread on the cultivation tray body 21, and then plant seedlings are planted in the soil. When the drive component 5 is working, the drive component 5 can drive the synchronous wheel 4 to rotate. Through the transmission action of the synchronous belt, the synchronous wheel 3 rotates. Through the rotation action of the synchronous wheel 3, the rotating shaft 22 fixedly connected to the synchronous wheel 3 rotates on the cultivation frame body 11, which in turn drives the cultivation tray body 21 to rotate. This rotation is continuous. Through the continuous rotation of the cultivation tray body 21, the plant seedlings planted on the cultivation tray body 21 are constantly changing positions, so that the seedlings receive more uniform light.

[0030] Reference Figure 3 , Figure 5 , Figure 6 and Figure 11As shown, the drive assembly 5 includes a motor 51, which is fixedly connected to the left side of the culture rack body 11. The motor 51 is located in the working cavity 52 formed by the protective cover 12 and the culture rack body 11. The output end of the motor 51 is fixedly connected to one end of the drive shaft 53. The drive shaft 53 is fixedly connected to the second synchronous pulley 4. The other end of the drive shaft 53 is fixedly connected to the first bevel gear 54. A transmission shaft 55 is rotatably connected to the left side of the culture rack body 11. A second bevel gear 56 is fixedly connected to the transmission shaft 55. The second bevel gear 56 is located in the working cavity 52. ​​The first bevel gear 54 meshes with the second bevel gear 56. A first gear 57 is also fixedly connected to the transmission shaft 55.

[0031] By starting the motor 51, the motor 51 drives the drive shaft 53 to rotate. When the drive shaft 53 rotates, it drives the synchronous pulley 4, which is fixedly connected to it, to rotate. Since the synchronous pulley 4 and the synchronous pulley 3 are driven by a synchronous belt, and the synchronous pulley 3 is fixedly connected to the rotating shaft 22, the rotation of the synchronous pulley 4 can cause the rotating shaft 22 to rotate. At the same time, when the drive shaft 53 rotates, it drives the bevel gear 54, which is fixedly connected to the drive shaft 53, to rotate. Since the bevel gear 54 meshes with the bevel gear 56, when the bevel gear 54 rotates, the bevel gear 56 rotates together, thereby driving the transmission shaft 55 to rotate on the cultivation rack body 11, and thus causing the gear 57 to rotate.

[0032] Reference Figure 5 As shown, the clutch assembly 6 includes a second gear 61, which is disposed in the working cavity 52 on the left side of the culture rack body 11. The second gear 61 is fixedly connected to one end of the slide rod 62, the slide rod 62 is slidably connected to the protective cover 12 on the left side of the culture rack body 11, the other end of the slide rod 62 is rotatably connected to one end of the connecting rod 63, and the other end of the connecting rod 63 is fixedly connected to the output end of the cylinder 64. The cylinder 64 is fixedly connected to the outside of the protective cover 12.

[0033] Reference Figure 3 , Figure 7 , Figure 11 and Figure 12 As shown, each of the several scattering components 7 includes a reflector 71, which is fixedly connected to the culture rack body 11. A mounting plate 72 is provided below the reflector 71, and a prism 73 is fixedly connected to the mounting plate 72. A nut 74 is fixedly connected to the mounting plate 72, and the nut 74 is threaded to a lead screw 75. The lead screw 75 is rotatably connected to the culture rack body 11, and a gear 76 is fixedly connected to one end of the lead screw 75. A guide rod 77 is fixedly connected to the culture rack body 11, and the mounting plate 72 is slidably connected to the guide rod 77. Several vision cameras 78 are fixedly connected to the culture rack body 11.

[0034] When the visual camera 78 detects poor seedling growth in certain areas, it transmits the monitoring information to the control system. The motor 51 stops rotating, and the transmission shaft 55 also stops rotating. The control system controls the cylinder 64 to retract. As the cylinder 64 retracts, it drives the connecting rod 63 to move synchronously, which in turn drives the slide rod 62 to slide. This causes the gear 2 61, which is fixedly connected to the slide rod 62, to mesh with gear 1 57 and gear 3 76. Because the teeth of gear 1 57, gear 2 61, and gear 3 76 are all rounded, there will be no mis-meshing due to tooth jamming during this process. At this time, the motor 51 rotates, causing gear 1 57 to rotate, and gear 2 61 to rotate simultaneously. Simultaneously, the slide rod 62 rotates on the protective cover 12. When gear 2 61 rotates, gear 3 76 rotates as well. When gear 3 76 rotates, it drives the lead screw 75, which is fixedly connected to it, to rotate. Because the lead screw 75 and nut 74 are threaded together, when the lead screw 75 rotates, the nut 74 causes the mounting plate 72 to slide on the guide rod 77, thereby driving the ridge... Mirror 73 slides along the axis of guide rod 77 until it reaches an area with poor growth. Then, cylinder 64 pushes connecting rod 63 to move in the opposite direction, causing connecting rod 63 to drive slide rod 62 to slide in the opposite direction. Slide rod 62 pulls gear 2 61 to disengage from gear 1 57 and gear 3 76. At this time, gear 3 76 stops rotating, screw 75 also stops rotating, and mounting plate 72 stops sliding on guide rod 77, thus stopping prism 73 from moving. Since reflector 71 is located above prism 73, and reflector 71... The length of the reflector plate assembly 9 is greater than that of the prism 73, and the prism 73 will not leave the area covered by the light reflected by the reflector 71 when it moves. At this time, the reflector plate assembly 9 reflects the sunlight onto the reflector 71, and then the light is reflected onto the prism 73 through the reflector 71. After the light is refracted by the prism 73, it covers the area where the plant seedlings are growing poorly, so as to provide supplemental lighting. When the cultivation tray body 21 rotates, it drives the plant seedlings to rotate synchronously. The seedlings will not leave the area covered by the light refracted by the prism 73 during the entire rotation process.

[0035] Reference Figure 6 and Figure 10 As shown, both push-pull components 8 include electric push rods 81. The two electric push rods 81 are respectively installed in the working cavities 52 on the left and right sides of the culture rack body 11. One end of the two electric push rods 81 is rotatably connected to the side wall of the culture rack body 11. The output end of the electric push rod 81 is rotatably connected to the upper end of the push-pull rod 82. When the electric push rod 81 extends or retracts, its output end has a pushing and pulling effect on the push-pull rod 82.

[0036] Reference Figure 3 , Figure 6 and Figure 9As shown, both push-pull assemblies 8 include two slide rails 83, which are fixedly connected to the inside of the protective cover 12. The two slide rails 83 are arranged longitudinally in the working cavity 52. ​​A slider 84 is slidably connected to each of the two slide rails 83. The slider 84 is slidably connected to the push-pull rod 82. The slider 84 is fixedly connected to one end of the spring 85, and the other end of the spring 85 is fixedly connected to the slide rail 83.

[0037] When slider 84 slides forward on slide rail 83, the spring 85 located behind slider 84 is stretched, and at the same time the spring 85 located in front of slider 84 is compressed.

[0038] Reference Figure 3 , Figure 8 and Figure 10 As shown, each of the several reflector assemblies 9 includes a reflector body 91. The several reflector bodies 91 are arranged longitudinally, and an angle adjustment shaft 92 is fixedly connected to each of the several reflector bodies 91. The two ends of the angle adjustment shaft 92 are fixedly connected to one end of two deflection rods 93 respectively. The angle adjustment shaft 92 is rotatably connected to the culture rack body 11. The other end of the deflection rod 93 is rotatably connected to the push-pull rod 82. A photodetector 94 is fixedly connected to the culture rack body 11.

[0039] When the photodetector 94 detects a change in the angle of incidence of sunlight on its plane, it transmits the detection information to the control system. The control system then controls the cylinder 64 to extend or retract, thereby causing the connecting rod 63 and the slide rod 62 to move synchronously. This causes gear 2 61 to disengage from or engage with gear 1 57 and gear 3 76. Due to the limiting effect of the deflection rod 93, the electric push rod 81 pushes or pulls the push-pull rod 82 relative to the two sliders 84, causing them to slide downwards or upwards. Simultaneously, it pushes the two sliders 84 to slide forwards or backwards on the slide rail 83. The spring 85 stretches or contracts, causing the deflection rod 93 to deflect downwards or upwards, which in turn causes the angle adjusting shaft 92 to rotate counterclockwise or clockwise. When the angle adjusting shaft 92 rotates counterclockwise or clockwise, it causes the reflector body 91 to deflect upwards or downwards. The angle between sunlight and the reflector body 91 is adjusted in this way so that the light shining on the reflector body 91 can be reflected to the seedling planting area to the maximum extent. When there is no sunlight, the reflector body 91 deflects upward at the maximum angle, so that the reflector body 91 has a certain shading effect on the open area of ​​the cultivation rack body 11. Since this device is usually installed indoors, in this case, due to the poor air circulation indoors, the shading effect of the reflector body 91 on the open area of ​​the cultivation rack body 11 is sufficient to prevent the plant from losing temperature too quickly, so as to keep the seedlings warm and make the ambient temperature more suitable for the growth of the seedlings. The wave-shaped structure, through the gradual curvature design, concentrates the light to be reflected to the seedling area at a preset angle.

[0040] Reference Figure 4 As shown, the reflector body 91 is wavy, and one side of the reflector body 91 is fixedly connected to the angle adjustment shaft 92.

[0041] As sunlight shines down, some of it falls onto the ground behind the cultivation rack body 11. The reflector body 91 extends outward to reflect the light that originally fell to the ground back to the area where the seedlings are located, providing them with photosynthesis. The wavy structure of the reflector body 91 adopts a gradual design, meaning the height of the wave gradually increases from front to back along the reflector body 91. When sunlight shines on the sun-facing side of the wave, it is reflected to the area where the seedlings are located. As the curvature of the sun-facing side of the wave changes, the reflected light can fully cover the entire longitudinal plane of the area where the plant is located. Combined with the rotation of the cultivation tray body, this results in more abundant lighting and better cultivation of the seedlings. The sunlight reflected to the top of the plant is reflected by the reflector 71. The light is directed onto the prism 73 and scattered by the prism 73, illuminating the seedlings from above. The angle of the reflector body 91 is adjusted in real time to ensure that the reflected light is focused on the seedling area, thus avoiding low energy density of the light reflected to the plant area due to changes in the angle of the light incident on the reflector body 91, while meeting the light intensity requirements of the plants. The movement of the prism 73 is controlled by feedback signals from the vision camera 78, and the position is calibrated through the precision transmission of the lead screw 75 to ensure that the refracted light covers the weak light area. The reflector 71 is fixed to the top of the cultivation rack, covering the entire longitudinal plane. When the prism 73 moves below it, it can receive reflected light from any position, and the movement range of the prism 73 matches that of the reflector 71, thus ensuring that the refracted light accurately covers the seedling area with different growth rates.
