Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural equipment technology, specifically to an intelligent plant seedling machine that can automatically track light sources, monitor environmental parameters, and enable human-computer interaction. Background Technology

[0002] With the rapid development of facility agriculture and home gardening, plant seedling equipment is gradually shifting from traditional static planting to intelligent management. However, existing technologies still have the following significant drawbacks:

[0003] (1) Passivity and inefficiency of light regulation: Most seedling equipment (such as the forestry seedling device described in CN216219039U) uses fixed-installation supplemental lighting or relies on natural light, which cannot be dynamically adjusted according to the sun's position, resulting in uneven distribution of light intensity. Especially in cloudy or rainy weather or indoor environments, the plant's light-receiving surface is singular, and the photosynthetic efficiency is significantly reduced. Although some equipment (such as the intelligent hydroponic device described in CN209768507U) improves light through LED supplemental lighting, it needs to be turned on all day, resulting in high energy costs, and the spectral range differs from that of natural light. Long-term use can easily lead to excessive growth or malformed development of plants.

[0004] (2) Insufficient motion control and adaptability: Existing equipment (such as the hydroponic monitoring device described in CN213637922U) mostly adopts horizontal rotation or fixed lifting structures, which cannot achieve coordinated movement in three-dimensional space. For example, traditional rotating cultivation racks can only rotate around a single axis, making it difficult to ensure that plant leaves are always perpendicular to the incident light, resulting in the shaded side being in a low-light state for a long time. Some lifting devices (such as hydraulic drive systems) have the risk of leakage, or gear transmission mechanisms (such as the garden maintenance robot described in CN206525205U) may jam due to insufficient load capacity, affecting long-term reliability.

[0005] (3) Lack of environmental monitoring and interactive functions: Existing technologies mostly rely on periodic manual detection (such as manually measuring soil moisture) or only collect data through simple sensors (such as a single temperature and humidity probe), lacking real-time fusion analysis of parameters such as light intensity, pH, and tilt angle. At the same time, traditional equipment lacks a visual interface and voice interaction function, and users cannot remotely obtain plant status or receive early warning information (such as water shortage alarm), which reduces the ease of use of the equipment and the user experience.

[0006] (4) Energy dependence and sustainability limitations: Most devices need to be continuously connected to the mains power, making them difficult to apply in areas without grid coverage (such as remote farmland or outdoor balconies). Although some studies have attempted to use solar power, the photovoltaic panels are fixed and cannot be adjusted with the movement of the equipment, resulting in low photoelectric conversion efficiency.

[0007] Based on the above problems, academia and industry have proposed some improvement solutions, but limitations still exist: 1. Preliminary exploration of light-tracking systems: CN213637922U monitors crop growth status through a camera, but only achieves passive image acquisition and is not linked with mechanical motion control; CN209768507U adopts a timed rotation strategy, lacking dynamic feedback adjustment based on light intensity. 2. Attempts at modular design: Some patents (such as CN216219039U) simplify seedling cultivation operations through detachable structures, but do not solve the problem of integrating environmental parameter monitoring with automated irrigation. 3. Localized solutions for energy consumption optimization: Existing solar energy equipment mostly uses fixed photovoltaic panels (such as CN206525205U0), which are not coupled with the equipment's moving mechanism, resulting in an energy utilization rate of less than 30%.

[0008] Based on the above analysis, there is an urgent need for an intelligent plant seedling cultivation device that features multi-degree-of-freedom motion control, real-time fusion feedback of environmental parameters, low energy consumption, and support for human-computer interaction. Summary of the Invention

[0009] The purpose of this invention is to provide an intelligent plant seedling machine to overcome the shortcomings of the prior art.

[0010] To achieve the above objectives, the present invention employs the following core design to fill a technological gap:

[0011] A smart plant seedling machine, characterized in that it comprises: a base, a rotating platform, a lifting device, a planting platform, a light-tracking system, and a control module; the rotating platform is mounted on the base and rotates around the Z-axis via a rotating drive component; the lifting device is mounted on the rotating platform and swings around the Y-axis via a lifting drive component; the planting platform is mounted on the lifting device and connected to a self-rotating drive component via a self-rotating transmission structure, enabling it to rotate around its own axis; the light-tracking system detects light differences using multiple photoresistors; the control module is electrically connected to the rotating drive component, the lifting drive component, the self-rotating drive component, and the light-tracking system, and is used to adjust the angle and position of the planting platform based on the detection data of the light-tracking system by controlling the rotating drive component, the lifting drive component, and the self-rotating drive component, so that the planting platform is always perpendicular to the incident light.

[0012] Furthermore, the rotating platform is connected to the rotating drive component via a worm gear transmission device, which includes a worm and a worm wheel. The worm is driven by the rotating drive component, and the worm wheel is fixedly connected to the rotating platform.

[0013] Furthermore, the lifting drive component drives the lifting device to rotate via a planetary gear transmission structure. The planetary gear transmission structure includes a meshing drive gear and a planetary gear ring. The lifting device includes a drive platform and a lifting platform, which are connected by a rotating hinge. The lifting drive component is mounted on the drive platform, and its output shaft is connected to the drive gear. The lifting platform is fixedly connected to the planetary gear ring. The lifting drive component drives the drive gear to rotate, and through the meshing of the drive gear and the planetary gear ring, the lifting platform rotates relative to the drive platform.

[0014] Furthermore, the self-rotation transmission structure is a gear transmission mechanism, including a gear slot and a transmission gear located at the bottom of the planting platform, and the transmission gear is connected to the output shaft of the self-rotation drive component.

[0015] Furthermore, the light-tracking system also includes a gyroscope module to assist in determining the sun's position.

[0016] Furthermore, the intelligent plant seedling machine also includes an interactive module, which includes a voice broadcast unit and an OLED display screen. The voice broadcast unit supports weather reports and equipment status prompts, while the OLED display screen can display plant growth parameters and dynamic emoticons.

[0017] Furthermore, the light-tracking system includes three photoresistors, respectively located on the left, right, and bottom sides of the planting platform. The resistance value of the upper side is calculated using the following formula:

[0018] Top resistance = (left resistance + right resistance) / 2;

[0019] The control module controls the drive components to adjust the position of the planting platform based on the resistance difference between the left and right sides and the resistance difference between the top and bottom.

[0020] Furthermore, the intelligent plant seedling machine also includes a water circulation system, including a water storage chamber, a water pump, and a temperature and humidity sensor. The temperature and humidity sensor monitors the soil moisture, and when the soil moisture is insufficient, the water pump automatically irrigates the plants using water from the water storage chamber.

[0021] Furthermore, the intelligent plant seedling machine also includes a photovoltaic energy storage module to power the equipment without an external power source.

[0022] Furthermore, the water storage cavity is located in the cavity between the inner and outer walls of the flowerpot, and a filter layer is provided at the bottom of the water storage cavity. The beneficial effects of this invention are:

This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0039] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the importance of the technical features shown.

[0040] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 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 invention according to the specific circumstances.

[0041] Example 1: Intelligent plant seedling machine in a home balcony setting

[0042] Please see Figures 1-9 Its core structure includes: a base 1, a rotating platform 2, a lifting device 3, a planting platform 4, a light-tracking system 5, and a control module. The base 1 serves as the supporting structure for the entire seedling machine, used to mount the machine on the platform. Considering that the equipment may need to be fixed in one position for a long time, or needs to be protected in certain exposed or harsh environments, bolt connection ports 11 can be designed on the base 1 to ensure stable fixation of the machine in different environments. The planting platform 4, lifting device 3, and rotating platform 2 are arranged in an upper-middle-lower structure, positioned above the base 1.

[0043] The rotating platform 2 is mounted above the base 1 and rotates around the Z-axis via a rotating drive 7 and a worm gear transmission device 21. The rotating drive can be a stepper motor. The worm gear transmission device 21 consists of a brass worm wheel and a steel worm. The worm is rigidly connected to the output shaft of the stepper motor via a coupling, and the worm wheel is fixed to the bottom of the rotating platform 2 with bolts. The reduction ratio of the worm gear transmission device 21 is 20:1. For every 20 rotations of the stepper motor, the worm wheel rotates once, achieving precise horizontal angle adjustment (±0.5° accuracy). When the tracking system 5 detects a difference in illumination between the left and right sides, the control module drives the stepper motor to rotate forward or backward, which in turn drives the worm wheel to rotate, causing the rotating platform 2 to rotate around the Z-axis until the resistance values ​​of the left and right photoresistors 51 are balanced. In some embodiments, a gear transmission device can be used instead of the worm gear transmission device 21. Gear transmission has the characteristics of high transmission accuracy, but it is not suitable for transmissions with large distances between shafts. Meanwhile, due to the parallel arrangement of the gears, the stepper motor needs to be installed vertically when mounting the gears. This requires sufficient space to be reserved in the design for the vertical installation of the first stepper motor. Worm gear drives are characterized by a large single-stage speed ratio. The maximum single-stage speed ratio of gear drives is generally around 1 / 10, while the speed ratio of worm gear drives can reach 1 / 70-1 / 100. Therefore, worm gear reducers can achieve a large speed ratio with a relatively small overall size. Furthermore, the worm gear shafts can be arranged perpendicularly without intersecting each other. This arrangement saves installation space for both the driving and driven gears while being convenient and efficient. In addition, worm gears can prevent reverse rotation. When the worm lead angle is less than the friction angle, theoretically, the worm gear cannot drive the worm, meaning a self-locking worm gear drive device can be designed.

[0044] To reduce rotational friction, a ball groove 22 can be provided between the mating surfaces of the rotating platform 2 and the base 1, with built-in lubricating balls. The lubricating balls can be stainless steel balls with a diameter of 5mm, thereby reducing rotational friction between the base 1 and the rotating platform 2.

[0045] The lifting device 3 is mounted above the rotating platform 2 and is driven by a lifting drive component to swing around the Y-axis. The lifting drive component and the lifting device 3 are connected by a planetary gear transmission structure 31, and the lifting drive component drives the lifting device 3 to rotate through the planetary gear transmission structure 33. The planetary gear transmission structure 33 includes a meshing drive gear and a planetary gear ring 332. The lifting device 3 includes a drive platform 31 and a lifting platform 32, which are connected by a rotating hinge 34. The lifting drive component can be a second stepper motor, which is fixedly mounted on the drive platform 31 by a first mounting bracket 35. Its output shaft is rigidly connected to the drive gear 331. The lifting platform 32 is fixedly connected to the planetary gear ring 332. The lifting drive component drives the drive gear 331 to rotate, and then, through the meshing of the drive gear 331 and the planetary gear ring 332, the lifting platform 32 rotates relative to the drive platform 31. The planetary gear transmission structure 33 fully utilizes the high load-bearing capacity of internal meshing. When the planting platform 4 is under load, its force direction is downward and inward (e.g., Figure 6 As shown, by designing the planetary gear ring 332 near the inner side according to the selected standard drive gear 331, good meshing between gears can be achieved, enabling the seedling machine to operate effectively. Simultaneously, a fixed cylinder 333 can be further designed in the symmetrical direction of the drive gear to assist the movement of the drive gear 331. Through the coordinated operation of the connecting bolts, gear transmission, and fixed cylinder 333, a stable triangular structure is formed, enabling the lifting platform 32 to achieve smooth lifting of the planting platform 4.

[0046] The planting platform 4 is installed above the lifting platform 32 and is connected to the self-rotation drive component 9 via a self-rotation transmission structure 41 to achieve rotation around its own axis. The self-rotation transmission structure 41 can be a gear transmission structure, consisting of a standard drive gear and a driven gear 412 designed accordingly based on the drive gear. The driven gear 412 can be a gear slot designed at the bottom of the planting platform 4 based on the number of teeth and module of the drive gear 411. The self-rotation drive component can be a third stepper motor, which is fixedly installed on the lifting platform 32 via a second mounting bracket 42. The drive gear is rigidly connected to the output shaft of the third stepper motor. Through the meshing transmission between the drive gear and the gear slot, the transmission between the third stepper motor and the planting platform 4 is realized, enabling the planting platform 4 to rotate and thus allowing the plants to receive light from all directions. In other embodiments, a belt drive can also be used to replace the traditional gear structure to realize the transmission between the third stepper motor and the planting platform 4. Belt drives have good flexibility, can mitigate impacts, absorb vibrations, and have a simple structure and low cost, making them suitable for mass production. However, belt drives have low efficiency and require a corresponding tensioning device, necessitating a robust and reliable fixation of the components during the design phase. When using belt drives on the planting platform 4, different weights can easily cause varying tension, leading to slippage. This embodiment of the invention employs a gear drive structure for the rotational transmission of the planting platform 4. Gear drives offer a constant transmission ratio, high transmission efficiency, reliable operation, long service life, and a compact structure. However, they require higher manufacturing and installation precision and are relatively more expensive.

[0047] The light-tracking system 5 senses changes in light intensity, ensuring that the planting platform 4 remains perpendicular to the light direction. The resistance of the photoresistors changes significantly with light intensity; therefore, three photoresistors 51 are used as the main sensors of the light-tracking system 5, installed on the left, right, and bottom sides of the sensor platform 53. The resistance value of the upper side is obtained using the formula: "Upper resistance = (Resistance of left photoresistor 511 + Resistance of right photoresistor 512) / 2". The difference between left and right resistances is determined by the formula: "Difference between left and right resistances = Resistance of right photoresistor 512 - Resistance of left photoresistor 512". This determines whether the difference is within a predetermined range and whether a left or right deflection (rotation around the Z-axis) is needed. Similarly, the difference between upper and lower resistances is determined by the formula: "Difference between upper and lower resistances = Upper resistance - Resistance of lower photoresistor 513". This determines whether an upper or lower deflection (rotation around the Y-axis) is needed, thus achieving closed-loop control of the planting platform 4. This ensures that when the light source appears on the horizon, the light can illuminate the plants from all directions. The left photoresistor 511 (pin A1) and the right photoresistor 512 (pin A3) are 50mm from the edge of the platform, while the lower photoresistor 513 (pin A2) is located below the center of the platform. The control module reads the resistance values ​​of the three photoresistors 51 in real time and calculates the difference (Δ) between the resistances of the left and right sides. L-R and the resistance difference between the upper and lower sides (Δ) U-D ), when Δ L-R >15 or Δ U-D When the light intensity is greater than 50, three stepper motors are triggered to dynamically adjust the position of the planting platform 4, ensuring that the planting platform 4 is always perpendicular to the incident light, thereby guaranteeing the light exposure of the plants and realizing intelligent planting.

[0048] To assist the tracking system 5 in directional control and to enable the machine to determine its own position and calculate the sun's angle, this embodiment of the invention can further incorporate a gyroscope module. Specifically, a rotatable MPU6050 six-axis gyroscope accelerometer module can be used. This compact module can simultaneously detect three-axis acceleration, three-axis gyroscope (three-axis angular velocity) motion data, and temperature data. Using the gyroscope data, the control module can determine the sun's position. Combined with temperature and ultraviolet radiation detection, it can also provide effective suggestions for the user's travel, further enhancing its intelligent functionality. The MPU6050 gyroscope is connected to the control module and can display data on an OLED display. When the device's position changes, the gyroscope promptly reads the data and displays it on the OLED screen.

[0049] To better align with smart home design principles and to imbue plants and machines with more vitality, interactive modules can be further integrated into the devices to enable information interaction and control. The interactive module includes an OLED display and a voice broadcast unit. The OLED display (0.96-inch, 128×64 pixels) connects to the control module via an I2C interface, displaying real-time data (light intensity, tilt angle) and dynamic emoticons. The voice broadcast unit uses a WT558D chip, storing 10 pre-recorded voice messages (such as "Insufficient light, adjusting angle"), and connects to an external speaker via a 3.5mm interface. In some other implementations, an E-ink screen can be used instead of OLED, reducing power consumption by more than 50%, but the refresh rate will be limited.

[0050] In some embodiments, the intelligent plant seedling machine may further include a water circulation system 6 for intelligent irrigation of the plants. The water circulation system 6 includes a temperature and humidity sensor, a water storage chamber 61, and a water pump 62. The humidity sensor is embedded 50mm deep in the planting substrate to detect soil moisture, and the temperature sensor detects the ambient temperature. When the humidity sensor detects soil moisture <30%, the control module starts the water pump 62 for 10 seconds of irrigation; when the humidity >70%, a voice alarm is triggered. In other embodiments, a capillary automatic irrigation system can also be used for irrigation, supplying water via fiber rope siphon, requiring no electricity, but this is only suitable for small potted plants (volume <2L).

[0051] Please see Figure 9 In some preferred embodiments, the water circulation system 6 can be designed inside the flowerpot, with the flowerpot designed as a double-layer structure. The cavity between the inner and outer walls of the pot is a water storage chamber 61, which can be used to collect rainwater on rainy days. A water pump 62 is installed at the top of the water storage chamber 61. At the same time, a filter layer 63 can be set at the bottom of the water storage chamber 61 to filter the soil carried down by excessive watering. Temperature and humidity sensors are installed on the inner wall of the pot to monitor the soil moisture at all times. When the soil moisture is insufficient, the control module drives the water pump 62 to operate, and water is irrigated through the water in the water storage chamber 61. This provides a micro-controlled water circulation function for the automatic irrigation of plants in a reasonable and effective manner.

[0052] Control Module: Electrically connected to three stepper motors, the tracking light system 5, and the water circulation system 6, used for motion control and data interaction. The core of the control module is the Arduino Nano development board, which connects to the stepper motor driver (TB6600), photoresistor 51, and water pump 62 via GPIO pins. The control module includes a Wi-Fi module (ESP-01S) that communicates with the Arduino via a UART interface and supports MQTT protocol data upload to the cloud.

[0053] In addition, the seedling machine can be further equipped with a photovoltaic energy storage module. By setting up solar panels to store energy and powering the equipment through a photovoltaic conversion circuit, the equipment can operate independently without an external power source.

[0054] The working principle of this invention is as follows:

[0055] 1. Initialization phase: After the device is powered on, the gyroscope calibrates the horizontal position, the OLED screen displays the startup animation, and the voice module announces "System ready".

[0056] 2. Light tracking cycle: The photoresistor 51 collects data every 5 seconds, and the control module calculates Δ. L-R Δ U-D The three-dimensional motion mechanism is driven to adjust the planting platform to the optimal position for light exposure.

[0057] 3. Environmental monitoring and irrigation: Temperature and humidity sensors detect soil conditions every minute, triggering automatic irrigation or alarms.

[0058] 4. Remote interaction: Users can view real-time data through the APP and manually override the automatic mode (such as forcing a 90° rotation).

[0059] Compared to traditional planting methods, the embodiments of the present invention improve planting efficiency as follows:

[0060] index Traditional equipment Embodiments of the present invention Increase Illumination uniformity 40%-60% 85%-90% +125% Daily energy consumption (household scenario) 1.2-1.5kWh 0.3-0.5kWh -67% Frequency of human intervention 1-2 times daily Once a week -86% Equipment failure rate (per year) 15%-20% <5% -75%

[0061] Example 2: Multi-machine collaborative system in a greenhouse setting

[0062] Multiple devices are networked via Wi-Fi, and centrally controlled by a Raspberry Pi 4, the movement paths of each device are dynamically allocated based on the light distribution within the greenhouse. Solar panel 11 can be upgraded to a foldable monocrystalline silicon panel (22% efficiency), with a total area of ​​0.5m². 2 It can power 3 devices.

[0063] The workflow is as follows:

[0064] 1. The central controller receives meteorological data and predicts trends in sunlight changes.

[0065] 2. The device closest to the window is raised to the highest position to prioritize tracking direct light.

[0066] 3. The remaining equipment should rotate horizontally in a "Z" shape to avoid obstructing each other.

[0067] Application scenarios of this invention include:

[0068] 1. Home Balcony: Suitable for potted vegetables (such as lettuce and tomatoes), automatically tracks diffused light on the balcony, with an average daily power consumption of <0.5kWh.

[0069] 2. Office Greenery: Equipped with a silent motor (noise <35dB), it uses emoticons to indicate the plant's status, enhancing the fun of the office environment.

[0070] 3. Agricultural greenhouses: Multiple machines clustered together achieve "solar energy sharing", and in conjunction with the integrated water and fertilizer system, the frequency of manual inspections is reduced by 80%.

[0071] The beneficial effects of the embodiments of the present invention include:

[0072] 1. Dynamic light tracking and three-dimensional motion control significantly improve photosynthetic efficiency.

[0073] Fully automatic light source tracking: Real-time detection of light intensity differences through photoresistors, combined with the three-dimensional linkage of horizontal rotation of worm gear, vertical lifting of planetary gears, and rotation of the planting platform, ensures that plant leaves are always perpendicular to the incident light, improving light uniformity by more than 40% (compared to traditional fixed supplemental lighting equipment).

[0074] Maximizing the utilization of natural light: relying entirely on sunlight tracking to replace artificial light sources reduces energy costs by 60%-80%, while avoiding problems such as excessive growth or abnormal development of plants caused by LED spectral deviations.

[0075] 2. Multi-sensor data fusion enables precise environmental control.

[0076] Closed-loop environmental monitoring: Integrating photoresistors, gyroscopes, and temperature and humidity sensors, it collects multi-dimensional data such as light intensity, equipment tilt angle, and soil moisture in real time. Through the control module algorithm, the data is fused and analyzed, and the environmental parameter monitoring accuracy reaches ±2% (the error of traditional single sensors is about ±10%).

[0077] Intelligent irrigation and early warning: The water circulation system automatically starts and stops the water pump according to the humidity threshold, and combined with the voice module, it broadcasts water shortage / over-humidity warnings, reducing the frequency of manual intervention by 90% and avoiding root rot or dehydration problems caused by improper maintenance.

[0078] 3. User-friendly human-computer interaction, supporting remote intelligent management

[0079] Status visualization and emotional interaction: The OLED display dynamically displays plant growth parameters (such as cumulative light duration and tilt angle) and anthropomorphic emoticons (such as a smiley face indicating good condition and a crying face indicating abnormality), improving user-friendliness by 70%.

[0080] IoT expansion capabilities: Connect to a mobile app via Wi-Fi module to remotely view data, adjust device angles, or schedule irrigation, making it especially suitable for users who travel frequently or lack gardening experience.

[0081] 4. Sustainable energy and modular design, applicable to a wide range of scenarios.

[0082] High-efficiency photovoltaic power supply: The base integrates a rotatable solar panel, which adjusts its angle synchronously with the movement of the equipment, achieving a photoelectric conversion efficiency of 22%-25% (compared to 15%-18% for fixed photovoltaic panels), meeting the continuous working needs of outdoor grid-free scenarios.

[0083] Modular compatibility and expansion: Core components (such as sensors and motor drives) adopt standardized interface design, which supports quick replacement or upgrade (such as adding CO2 sensors and UV monitoring modules), reducing maintenance costs by 50%, and adapting to the needs of multiple scenarios such as home balconies, agricultural greenhouses, and office greenery.

[0084] 5. Balancing the reliability and economy of mechanical structures

[0085] High load and low wear transmission: The worm gear reducer (20:1 reduction ratio) and planetary gear structure (module 1, number of teeth 82) work together to achieve a load capacity of 10kg, with operating noise below 40dB and a life of over 50,000 hours.

[0086] Feasibility of low-cost mass production: The core control module adopts open-source hardware (Arduino Nano), and 3D printed structural parts account for more than 70%, reducing the overall manufacturing cost by 30%-40% compared with similar commercial equipment.

[0087] 6. Social Benefits and Environmental Value: Energy Saving and Emission Reduction: By replacing artificial lighting with natural light tracking, a single unit can save approximately 200-300 kWh of electricity annually and reduce carbon emissions by 150-200 kg. Urban Agriculture Promotion: Providing automated solutions for family farming and community farms in high-density urban environments, promoting green living and sustainable agricultural development.

[0088] This invention systematically solves the pain points of existing plant seedling equipment, such as low light efficiency, high energy consumption, poor interactivity, and weak adaptability, through four core technologies: dynamic light tracking algorithm, multi-degree-of-freedom mechanical structure, sensor fusion, and Internet of Things interaction. It combines technological innovation, practicality, and economy, providing an efficient and reliable solution for smart agriculture and home gardening.
