Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent agricultural equipment, in particular to a full-automatic plant factory environment management system. BACKGROUND

[0002] Plant factory is a high-efficiency agricultural system that realizes the year-round continuous production of crops through high-precision environmental control. However, the existing technology still faces many severe challenges in practice: In a completely controlled artificial environment, plants lack external stimuli such as wind and rain in nature. This "static" environment can cause weak stems, thin cell walls, and underdeveloped mechanical tissues in plants, which is known as the "greenhouse effect", seriously affecting the stress resistance and quality of plants. For example, leafy vegetables such as lettuce and spinach are prone to overgrowth and lodging.

[0003] Traditional multi-layer cultivation racks improve space utilization, but the upper cultivation racks can cause serious light shading to the lower layers. Existing rotating cultivation racks mostly use a whole rotating method, which cannot effectively solve the problem of interlayer shading, and the insufficient light of lower plants leads to uneven growth.

[0004] The existing environmental control system of plant factory mostly uses fixed pipe air supply, which is difficult to avoid airflow dead angles, leading to uneven distribution of CO2, temperature, and humidity in the cultivation space, affecting the consistency of crop growth.

[0005] Therefore, there is an urgent need in the field for a comprehensive solution that can solve the problems of environmental uniformity, light distribution, and plant resistance improvement, and has a simple and reliable structure. SUMMARY

[0006] The purpose of the present application is to overcome the shortcomings of the prior art and provide a full-automatic plant factory environment management system that not only realizes precise environmental control but also actively promotes plant physiological health.

[0007] The full-automatic plant factory environment management system of the present application comprises a fixedly installed central static main shaft; a sleeve mounted on the central static main shaft through a bearing, the sleeve being capable of rotating around the central static main shaft; three layers of cultivation discs with diameters increasing from top to bottom, including an upper ring-shaped cultivation disc, a middle ring-shaped cultivation disc, and a lower ring-shaped cultivation disc; symmetrical through grooves are formed in the side wall of the sleeve; the upper ring-shaped cultivation disc and the lower ring-shaped cultivation disc are respectively connected with the corresponding grooves through a first connecting rod; the middle ring-shaped cultivation disc is fixedly connected with the corresponding grooves through a second connecting rod; a relative lifting mechanism for driving the upper ring-shaped cultivation disc and the lower ring-shaped cultivation disc to perform synchronous and opposite vertical movements; Periodic shaking device for making plants on upper, middle and lower annular cultivation trays reciprocate; The periodic shaking device is triggered by rotation of the sleeve, and the reciprocation of the plants is mechanically linked with rotation of the cultivation trays.

[0008] The relative lifting mechanism comprises a bidirectional reverse-threaded lead screw driven by a servo motor. Two nuts respectively engaged with the positive and reverse threaded segments of the lead screw; two C-shaped chucks each fixedly connected with a corresponding nut via a third connecting rod; the C-shaped chuck has an arc-shaped structure, a wave-shaped protrusion is arranged on the edge, and a ball bearing is arranged on the inner side of the C-shaped chuck; the C-shaped chuck is slidably connected with the cultivation trays.

[0009] The periodic shaking device comprises a support plate arranged in the upper, middle and lower annular cultivation trays. A sliding block fixed with the support plate, the sliding block moves along a guide rail, and the guide rail is fixedly connected with the cultivation trays; A spring for pulling the sliding block, the spring is fixedly connected with the guide rail; A roller connected with the sliding block, the roller can reciprocate radially along the wave-shaped protrusion of the C-shaped chuck.

[0010] The automatic plant factory environment management system further comprises a gas path control system, which comprises: The central static main shaft is internally provided with a partition plate to form at least one independent gas passage; Three groups of main shaft air holes are arranged on the central static main shaft corresponding to each cultivation tray; Three groups of sleeve air holes are arranged on the inner wall of the sleeve corresponding to each position; The sleeve is driven to rotate to change the coincidence degree of the sleeve air holes and the main shaft air holes, so as to realize the on-off of the gas path.

[0011] The automatic plant factory environment management system, wherein the gas passage comprises an ozone passage for conveying ozone and a carbon dioxide passage for conveying carbon dioxide.

[0012] The automatic plant factory environment management system further comprises a three-dimensional irrigation module, which comprises a water conveying pipeline arranged on the middle cavity of the central static main shaft and a spray head on the water conveying pipeline.

[0013] The full-automatic plant factory environment management system, wherein at least one of the sleeve ventilation holes is provided with a mist elimination assembly, the mist elimination assembly is driven by inertial force generated when the sleeve rotates to vibrate the gas sprayed from the sleeve ventilation hole.

[0014] The full-automatic plant factory environment management system, wherein the mist elimination assembly comprises an outer shell fixed to the sleeve and covering the periphery of the sleeve ventilation hole. A vibration mechanism arranged in the outer shell, comprising a movement shaft and elastic components symmetrically arranged at both ends of the movement shaft. At least one inertial component is connected with the movement shaft. When the sleeve rotates, the inertial component generates displacement due to inertia and drives the movement shaft to reciprocate, thereby causing the elastic components to vibrate.

Forced gas exchange and sterilization mode: control the sleeve to rotate to the position where all ozone channels are opened, and control the relative lifting mechanism to drive the cultivation disc to perform rapid and short-stroke relative reciprocating lifting motion, and use the piston effect to enhance ozone diffusion.

Through periodic shaking, the natural wind effect is simulated to promote the stem of the plant to be thick and strong, and to reduce the attachment of pests on the leaf surface. Three-dimensional composite motion ensures uniform distribution of environmental factors such as light, airflow, temperature and humidity. The relative lifting motion forms a forced airflow in the vertical direction, effectively promoting gas exchange and uniform distribution. Deep integration of mechanical air path switch and motion control realizes precise environmental regulation and control.

[0017] The full-automatic plant factory environment management system will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0021] 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.

[0022] Please seeFigures 1-9 Specifically, the following embodiments are included: Example 1: like Figures 1-3 As shown, the system frame consists of a base 220 and four support columns 221. The central static spindle 101 is vertically fixed to the center of the base 220.

[0023] The sleeve 102 is made of POM engineering plastic and CNC machined, or it can be made of seamless steel pipe. It is mounted on the central static spindle 101 by two sets of upper and lower angular contact ball bearings, so that it can rotate smoothly. The sleeve 102 has symmetrical guide grooves 103 that run vertically through it on both sides of its outer wall.

[0024] The upper ring cultivation tray 120, the middle ring cultivation tray 121, and the lower ring cultivation tray 122 are all made of food-grade ABS plastic injection molding, or stainless steel plate can be used. One end of the first connecting rod 131 of each layer is fixed on the upper ring cultivation tray 120 and the lower ring cultivation tray 122 respectively. The other end of the first connecting rod 131 is equipped with a guide block, which can slide freely after being inserted into the corresponding guide groove 103. One end of the second connecting rod 132 is fixed on the middle ring cultivation tray 121, and the other end is fixed to the guide groove 103 by screws.

[0025] The relative lifting mechanism 2 includes a bidirectional reverse-threaded lead screw 104 driven by an AC servo motor 105. Two nuts 106 are respectively engaged in the limiting guide rails. Each nut 106 is fixedly connected to a C-shaped chuck 107 via a third connecting rod 133. When the sleeve 102 rotates, it drives all the cultivation trays to revolve synchronously through the guide groove 103, solving the problem of uniform light intensity in the horizontal plane. The relative lifting mechanism 2 drives the upper annular cultivation tray 120 and the lower annular cultivation tray 122 to move in opposite directions, generating a piston effect to improve the vertical gas distribution and solve the problem of light shading. The servo motor 105 drives the lead screw 104 to rotate, and the two nuts 106 move towards or away from each other due to the opposite thread direction, which is converted into linear lifting motion of the upper annular cultivation tray 120 and the lower annular cultivation tray 122 through the C-shaped chuck 107.

[0026] The C-shaped chuck 107 has an arc-shaped structure with regularly arranged wavy protrusions 108 along its edge. A ball bearing 109 is embedded inside the C-shaped chuck 107, allowing it to firmly and with low resistance "hold" the outer edge of the cultivation tray. The ball bearing 109 ensures that the cultivation tray can still rotate freely during lifting and lowering. See the diagram for the structure of the periodic shaking device 3. Figure 3Each cultivation tray contains a support plate 110, which is fixedly connected to a slider 111. The slider 111 can move along a guide rail 112, which is fixed to the cultivation tray and held in its initial position by a spring 113. One end of the spring 113 is fixed to the guide rail 112, and the other end is fixed to the slider 111. The slider 111 is connected to a roller 114, which can reciprocate radially along the wavy protrusions 108.

[0027] When the sleeve 102 rotates, the roller 114 rotates to the position of the C-shaped chuck 107. The wave protrusion 108 on it pushes the roller 114 to produce radial displacement, which in turn drives the tray 110 to reciprocate through the slider 111, causing the potted plants on the tray 110 to shake periodically.

[0028] The wave protrusion 108 is detachably mounted on the C-shaped chuck 107 and can be removed when no shaking is required.

[0029] The middle layer annular cultivation tray 121 is also provided with a C-shaped chuck 107 on its edge, which is fixedly connected to one end of the auxiliary rod, and the other end of the auxiliary rod is fixed to the limiting guide rail, so that the middle layer annular cultivation tray 121 can rotate, but does not move longitudinally back and forth.

[0030] Wherein, the present invention is as follows Figure 1 As shown, the overall structure is symmetrical, and will not be repeated when describing the specific structure of the present invention.

[0031] The first connecting rod 131 fixed to the upper annular cultivation tray 120 and the first connecting rod 131 connected to the lower annular cultivation tray 122 differ only in length, and are therefore collectively referred to as the first connecting rod 131.

[0032] Example 2: like Figure 4 and Figure 5 As shown, the central static main shaft 101 is divided into three cavities by a partition 125. The two side cavities form gas channels, namely ozone channel 115 and carbon dioxide channel 116. The central static main shaft 101 has three sets of main shaft ventilation holes 117 at the corresponding height of each cultivation tray, and sleeve ventilation holes 118 of the same specifications are opened at corresponding positions on the inner wall of the sleeve 102. Both adopt a conical design, larger inside and smaller outside, to reduce airflow resistance. The rotation of the sleeve 102 is driven by a stepper motor through a reduction gear set. When gas needs to be introduced, ozone or carbon dioxide is introduced. The rotation of the sleeve 102 opens the main shaft ventilation holes 117 and the sleeve ventilation holes 118. When stopped at a specific angle, they are normally open or normally closed; when continuously rotating, they are intermittently open and closed. Integrating two functional gases into the same shaft body results in a compact structure. Combined with a mechanical switch, time-sharing supply can be achieved, for example, supplying CO2 during the day to promote photosynthesis and supplying ozone at night for sterilization, without interference.

[0033] The three-dimensional irrigation module includes a water supply pipe 119 disposed on the central cavity of the central static main shaft 101 and a nozzle on the water supply pipe 119. The water supply pipe 119 is connected to an external water supply system.

[0034] A nozzle is provided on the vent hole 118 of the sleeve to guide the gas out.

[0035] Example 3: In this embodiment, refer to Figures 6-9 To reduce liquefaction of gases, especially CO2, generated when the sleeve vent 118 is discharged, an anti-fogging component 4 is installed on the nozzle at the sleeve vent 118. The anti-fogging component 4 includes a housing 40 and a vibration mechanism 41. The housing 40 is fixed to the sleeve 102 and covers the periphery of the sleeve vent 118. The vibration mechanism 41 includes a motion shaft 42 and elastic components 400 located at both ends of the motion shaft 42. Specifically, as... Figure 7 As shown, the two elastic components 400 differ only in size. Each elastic component 400 includes multiple rubber ropes 401. One end of each rubber rope 401 is fixed to the motion shaft 42, and the other end is fixed to a limiting ring 402. The limiting ring 402 is fixed to the outer shell 40.

[0036] Furthermore, the motion shaft 42 is connected to two symmetrically arranged inertial components 43. The inertial components 43 include guide rods 4001, which are fitted inside guide cylinders 4003. The guide cylinders 4003 are fixed to the outer shell 40. A return spring 4002 is installed inside the guide cylinders 4003. When the sleeve 102 is not rotating, neither of the two guide rods 4001 is in contact with its respective return spring 4002. When the sleeve 102 rotates, due to inertia and the rubber ropes 401 not being taut, the guide rods 4001 will touch the return springs 4002. The rebound force of the return springs 4002 is used to realize the reciprocating movement of the guide rods 4001, thereby causing the motion shaft 42 to reciprocate, which in turn causes the multiple rubber ropes 401 to vibrate continuously.

[0037] The present invention includes an anti-fogging component 4. After the gas is ejected from the nozzle through the vent hole 118 of the sleeve, it is continuously vibrated by multiple rubber ropes 401. This reduces the amount of gas that adheres to the area around the nozzle after liquefaction, thus preventing nozzle blockage. The generated micro-vibration waves also disturb the airflow field at the nozzle outlet. This disturbance helps to break the laminar flow state of the ejected gas and promotes its instantaneous mixing with the surrounding air. This helps to improve the initial uniformity of CO2 or ozone distribution in the plant canopy on a microscale, which is beneficial to complement the macroscopic "piston effect" of the system.

[0038] Example 4: The control system uses an industrial-grade microcontroller as the main controller and is equipped with: Sensor modules: light sensor, temperature and humidity sensor, CO2 sensor, soil moisture sensor; Actuator drive module: servo driver, stepper driver, relay group; Communication modules: Wi-Fi module, 4G module.

[0039] The system has four preset working modes: Mode 1: Uniform Lighting and Three-Dimensional Irrigation Mode The three cultivation trays rotate slowly and synchronously. At the same time, the lead screw 104 drives the upper annular cultivation tray 120 and the lower annular cultivation tray 122 to perform slow, periodic relative lifting and lowering movements.

[0040] The advantages of this mode are: extremely uniform light: rotation eliminates the blind spots in light on a single-layer plate; relative lifting combined with the gradually increasing diameter design completely solves the problem of shading between layers, ensuring that plants in all positions can receive almost equal light.

[0041] Full irrigation coverage: The top sprinklers activate during the system's raising and lowering process, allowing water to cover all moving plants and achieve thorough spraying without any blind spots.

[0042] Mode 2: Forced Gas Exchange and Sterilization Mode The controller commands the sleeve 102 to rotate to a specific angle, opening the ozone channels 115 in all layers. At the same time, it drives the three cultivation trays to perform rapid, short-stroke relative reciprocating lifting and lowering movements.

[0043] The advantages of this mode are: "Piston effect": The relative motion between the upper annular cultivation tray 120 and the lower annular cultivation tray 122 violently stirs the air in the vertical direction, forming strong turbulence. This piston-like airflow organization can effectively break the static air boundary layer on the blade surface. Specifically, the piston effect manifests as follows: when the upper annular cultivation tray 120 descends and the lower annular cultivation tray 122 rises, it compresses the air in the middle layer to diffuse outwards; when the upper annular cultivation tray 120 rises and the lower annular cultivation tray 122 descends, it draws fresh air from the surroundings to replenish the middle layer. This reciprocating motion forms strong vertical turbulence, effectively promoting the mixing and distribution of gases such as CO2 and ozone. Compared with traditional fans, the airflow generated by the piston effect is more uniform, without dead zones, and consumes less energy.

[0044] Highly efficient sterilization: Under this strong turbulence, ozone can quickly and evenly diffuse to the surface and back of every leaf, achieving a sterilization effect comparable to a strong wind, effectively preventing diseases.

[0045] Mode 3: High-efficiency utilization mode of carbon dioxide fertilizer During periods of sunlight, the controller only activates the carbon dioxide channel 116. The system maintains slow rotation but suspends the relative lifting mechanism 2, maintaining only minimal airflow disturbance.

[0046] The advantages of this model are: it precisely delivers high concentrations of CO2 to the areas that need it most, avoiding ineffective waste. A moderate airflow is sufficient to evenly distribute CO2 around the plants in this layer, but it doesn't disperse it too quickly, ensuring that the plants "breathe" a high concentration of "air fertilizer."

[0047] Mode 4: Humanized Harvesting Mode The controller drives the lead screw 104 to lower the upper ring cultivation tray 120 to its lowest position, raise the lower ring cultivation tray 122 to its highest position, and place the middle ring cultivation tray 121 in the middle, forming a staggered and easy-to-operate layout.

[0048] Standing on the ground, staff can easily operate all three layers of plants within arm's reach, greatly reducing labor intensity and improving work efficiency and safety.

[0049] System workflow: After the system starts up, the controller first performs a self-test to confirm that all sensors and actuators are in normal working order. Then, it enters the corresponding working mode according to the preset program or remote command.

[0050] Under normal growth mode, the system operates according to the following process: The three cultivation trays rotate synchronously to ensure uniform light exposure within each layer. The lead screw 104 rotates slowly, driving the upper annular cultivation tray 120 and the lower annular cultivation tray 122 to move relative to each other. When the CO2 concentration is lower than the set value, the controller adjusts the CO2 delivery equipment to supply it, and the rotation of the sleeve 102 automatically opens the gas path. When the soil moisture sensor triggers irrigation, the water supply pipeline 119 for replenishing water is activated; The relative lifting mechanism 2 continues to work, providing mechanical stimulation to the plants; The system records environmental data in real time and performs remote monitoring and data analysis through a cloud platform.

[0051] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
