Description

Technical Field

[0001] This invention relates to the field of bayberry tree planting and management technology, specifically to a smart agricultural bayberry growth environment control system. Background Technology

[0002] The Chinese bayberry (Yangmei) is a distinctive and advantageous fruit tree in southern my country, with strict and specific environmental requirements for its growth and development. This species prefers a warm and humid climate, with an optimal average annual temperature of 15℃–21℃ and a relative humidity of 70%–85%. It is intolerant of low-temperature damage and drought stress; the extreme minimum temperature for its growth environment should not fall below -9℃, and the soil moisture content should be maintained at 60%–80% of field capacity. It also has stringent requirements for soil physicochemical properties, thriving in acidic sandy loam with a pH of 4.5–6.5. Furthermore, the environmental requirements of the Chinese bayberry vary significantly at different growth stages. Flower bud differentiation requires a low temperature of 5℃–10℃ for induction, while fruit enlargement requires a stable temperature environment of 20℃–25℃. Precise regulation of environmental factors directly determines the quality of flower bud differentiation, fruit set rate, fruit commercial quality, and ripening time.

[0003] While existing environmental control systems for facility agriculture can automatically regulate factors such as temperature, humidity, light, and water and fertilizer by collecting environmental parameters inside the greenhouse, the traditional method of direct ventilation through open windows is still widely used. This ventilation mode lacks effective air purification and pest control / sterilization structures. Direct airflow between the inside and outside of the greenhouse allows adult insects, eggs, and pathogens carried by the outside airflow to easily enter the greenhouse, attach to the bayberry plants, and multiply, causing pests and diseases. These problems not only significantly increase the pressure on plant protection and control within the greenhouse but also reduce bayberry yield and fruit quality, making it difficult to meet the production requirements of facility-based, refined, and green bayberry cultivation. Summary of the Invention

[0004] In view of this, the present invention proposes a smart agricultural bayberry growth environment control system to reduce the entry of pests into the greenhouse through ventilation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Both the air intake device and the air exhaust device are embedded in the greenhouse frame. The air intake device includes an air intake pipe and a filter insect killer. The air intake pipe is provided with a first air inlet, a second air inlet, and multiple air outlets. The first air inlet is located on the outside of the greenhouse, the second air inlet is located inside the greenhouse, and the air outlets are arranged at intervals on the pipe body of the air intake pipe. The filter insect killer is fixedly installed on the air intake pipe and is located between the air outlets and the air inlets.

[0008] The growth monitoring system includes a growth status monitoring unit, an environmental data acquisition unit, and an environmental control host.

[0009] The growth monitoring unit includes multiple cameras, and the environmental data acquisition unit includes an air humidity sensor, a water and fertilizer sensor, a temperature sensor, a pH sensor, a light sensor, and a carbon dioxide concentration sensor.

[0010] Both the growth monitoring unit and the environmental data acquisition unit transmit the acquired data to the environmental control host. The environmental control host is electrically connected to the air intake device, exhaust device, heating device, cooling device, supplemental lighting device, and irrigation system, and is used to control the operation of each device based on the received data.

[0011] To better implement the above technical solution, optionally, the second air inlet of the air inlet pipe is connected to the air outlet of the refrigeration device to introduce the refrigerated air into the greenhouse to form an internal circulation.

[0012] Optionally, the filter insect killer includes a housing, a filter assembly, an insecticidal lamp, a first cleaning mechanism, and a second cleaning mechanism;

[0013] The filter assembly includes a drive assembly, a transmission unit, and an annular filter screen. The transmission unit is rotatably disposed at the left and right ends inside the housing. The annular filter screen is sleeved on the transmission unit. The drive assembly is driven to the transmission unit and is used to drive the transmission unit to drive the annular filter screen to perform a cyclic rotation.

[0014] The first cleaning mechanism is disposed inside the housing and located outside the annular filter screen, and is used to clean the outer layer of the annular filter screen;

[0015] The second cleaning mechanism is located on the inner side of the annular filter screen and is used to clean the inner layer of the annular filter screen.

[0016] The insecticidal lamp is fixed to the inner middle of the annular filter.

[0017] Optionally, the transmission unit includes a drive shaft and a driven shaft, the internal width of the housing is greater than the width of the air inlet pipe, the drive shaft and the driven shaft are rotatably mounted on opposite sides of the inner cavity of the housing, and the inner ring of the annular filter mesh is driven and engaged with the drive shaft and the driven shaft respectively.

[0018] Optionally, the first cleaning mechanism includes a first cleaning brush with a U-shaped cross-section, the bristles of the first cleaning brush elastically abutting against the outer layer of the annular filter.

[0019] Optionally, the outer casing is detachably connected to a first sealing cover below the first cleaning brush, and the lower end of the first cleaning brush is rotatably inserted into a socket inside the first sealing cover, with a first dirt-collecting groove formed between the side ring wall of the first sealing cover and the inside of the socket.

[0020] Optionally, the second cleaning mechanism includes a second cleaning brush with a rectangular cross-section, the bristles of the second cleaning brush elastically abutting against the inner layer of the annular filter.

[0021] Optionally, the housing is detachably connected to a second sealing cover below the second cleaning brush. The lower end of the second cleaning brush is rotatably inserted into a socket inside the second sealing cover, and a second dirt-collecting groove is formed between the side ring wall of the second sealing cover and the socket.

[0022] Optionally, the annular filter screen includes an outer filter screen, a silver ion antibacterial meltblown nonwoven fabric, and an inner filter screen arranged sequentially from the outside to the inside.

[0023] The beneficial effects of this invention are:

[0024] The intelligent agricultural bayberry growth environment control system of this invention, in the air intake stage, the airflow sequentially passes through the outer filtration section of the composite annular filter to intercept large particles and some pests, and then through the inner filtration section to precisely filter the remaining small impurities and escaped pests. Simultaneously, relying on the antibacterial and insecticidal effect of the silver-loaded antibacterial meltblown nonwoven fabric in the filter interlayer, combined with the physical killing effect of the insecticidal lamp inside the filter on the intercepted pests, a dual-killing treatment is achieved for pests and pathogenic microorganisms captured by the inner and outer layers of the filter, constructing a closed-loop purification system for air intake with double-layer physical filtration and dual synergistic insecticidal action. The synergistic linkage between the insecticidal lamp and the composite annular filter significantly improves the thoroughness of pest and pathogenic microorganism elimination, and effectively avoids secondary airflow pollution caused by insect carcasses and impurities, enhancing the comprehensiveness and operational reliability of air intake purification, and creating a clean airflow environment free of pests and pathogens for the growth of bayberry plants in the greenhouse.

[0025] This invention relates to a smart agricultural bayberry growth environment control system. Utilizing a circular rotating filter mechanism and a dual-sided cleaning system, the outer U-shaped brush eliminates blind spots through elastic contact, while the inner double-sided brushes form a double sweeping action, continuously cleaning contaminants from both the inner and outer layers of the filter. A detachable, sealed cover and a collection groove allow for easy discharge of insect carcasses and impurities after gravity collection, preventing contaminants from clogging the mesh or being re-entrained by airflow. This system solves the problems of traditional filters being prone to clogging and cumbersome cleaning, ensuring stable airflow and filtration accuracy over a long period, and extending the filter's lifespan.

Detailed Implementation

[0034] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0035] Please see Figures 1 to 6 This invention discloses a smart agricultural bayberry growth environment control system, including a greenhouse, an air intake device 20, an exhaust device, a heating device, a cooling device, a supplemental lighting device, an irrigation system, and a growth monitoring system.

[0036] The greenhouse includes a greenhouse frame 10, a transparent film 11 covering the surface of the greenhouse frame 10, and a shading film 12 located above the top of the greenhouse frame 10. An air inlet device 20 and an exhaust device are both embedded in the greenhouse frame 10. The air inlet device 20 includes an air inlet pipe 21 and a filter insect killer 22. The air inlet pipe 21 has a first air inlet 211, a second air inlet 212, and multiple air outlets 213. The first air inlet 211 is located on the outside of the greenhouse, the second air inlet 212 is located inside the greenhouse, and the air outlets 213 are spaced apart on the pipe body of the air inlet pipe 21. The filter insect killer 22 is fixedly installed on the air inlet pipe 21 and located at the air outlet. Between port 213 and air inlet; the growth monitoring system includes a growth status monitoring unit, an environmental data acquisition unit, and an environmental control host; the growth status monitoring unit includes multiple cameras, and the environmental data acquisition unit includes an air humidity sensor, a water and fertilizer sensor, a temperature sensor, a pH sensor, a light sensor, and a carbon dioxide concentration sensor; both the growth status monitoring unit and the environmental data acquisition unit transmit the collected data to the environmental control host, which is electrically connected to the air inlet device 20, the exhaust device, the heating device, the cooling device, the supplementary lighting device, and the irrigation system, respectively, and is used to control the operation of each device according to the received data.

[0037] In this embodiment, multiple cameras are installed on the top of the greenhouse, covering as much of the branches and leaves of each bayberry tree as possible. Water and fertilizer sensors and pH sensors are installed at the roots of each bayberry tree.

[0038] In this embodiment, it should be noted that: a fan is installed in the air inlet pipe 21 of the air inlet device 20, which drives the air outside the shed to enter the shed; a one-way valve is installed in the exhaust device to prevent the air outside the shed from entering the shed through the exhaust device.

[0039] This invention discloses a smart agricultural bayberry growth environment control system. The environmental control host has a built-in database of environmental parameter thresholds suitable for the entire growth cycle of bayberries. It employs closed-loop control logic to perform multi-dimensional analysis of the collected data. When the air humidity sensor reading is below 70% or above 85%, the environmental control host synchronously activates the air intake device 20, exhaust device, and irrigation system. By adjusting the air intake speed, exhaust frequency, and irrigation volume, the air humidity inside the greenhouse is quickly restored to the suitable range. When the temperature sensor reading deviates from the suitable range of 15℃~21℃, if the temperature is too high, the system is controlled... The cooling system starts, introducing cooling air through the second air inlet 212 to form an internal circulation cooling system. If the temperature is too low, the heating system starts and the first air inlet 211 is switched to allow air to enter. After being purified by the insect filter 22, warm air is introduced. When the carbon dioxide concentration sensor detects a value below 800 ppm, the environmental control unit controls the first air inlet 211 to open and the second air inlet 212 to close, driving the air intake device 20 to introduce outside air. At the same time, the insect filter 22 intercepts mosquitoes, insect eggs, and fungal spores, ensuring the replenishment of carbon dioxide while preventing the invasion of external pests. When the light transmits... When the sensor readings are below the light intensity threshold required for the growth of the bayberry, the supplemental lighting device is activated and the duration and intensity of light are adjusted to meet the photosynthetic needs of the branches and leaves. When the pH sensor and water and fertilizer sensor detect that the soil pH exceeds the range of 4.5-6.5 or the soil fertilizer concentration is abnormal, the environmental control host precisely controls the water and fertilizer ratio and irrigation amount of the irrigation system to achieve targeted adjustment of the soil's physical and chemical properties. Images of bayberry branches and leaves collected by multiple cameras are analyzed by the image recognition module built into the environmental control host to identify signs of leaf diseases and pests and abnormal growth (such as yellowing and wilting of leaves) in real time. It triggers corresponding control strategies. At the same time, during the operation of the air intake device 20, the environmental control host can automatically switch the air intake mode according to the environmental parameter requirements inside the greenhouse: when fresh air needs to be introduced, the first air intake 211 is opened and the second air intake 212 is closed, and the air outside the greenhouse is introduced through the air intake pipe 21. When it is necessary to maintain the stability of the environment inside the greenhouse, it switches to the air intake mode of the second air intake 212 and the first air intake 211 is closed, and the air inside the greenhouse forms an internal circulation, avoiding environmental fluctuations and pest intrusion risks caused by frequent external circulation, and realizing the precise control of all parameters of the bayberry growth environment and the integration of green pest control.

[0040] like Figures 3 to 6As shown, the insect filter 22 includes a housing 220, a filter assembly, an insecticidal lamp 227, a first cleaning mechanism, and a second cleaning mechanism. The filter assembly includes a drive assembly, a transmission unit, and an annular filter 226. The transmission unit is rotatably disposed at both ends inside the housing 220. The annular filter 226 is fitted onto the transmission unit. The drive assembly is driven to the transmission unit to drive the transmission unit to rotate the annular filter 226. The first cleaning mechanism is disposed inside the housing 220 and located outside the annular filter 226, and is used to clean and remove impurities from the outer layer of the annular filter 226. The second cleaning mechanism is disposed on the edge inside the annular filter 226, and is used to clean the inner layer of the annular filter 226. The insecticidal lamp 227 is fixedly disposed in the middle of the inner side of the annular filter 226.

[0041] During air intake operation, the airflow in the intake duct 21 first undergoes primary filtration through the front filtration section of the annular filter 226, then flows through the area of ​​the insecticidal lamp 227 for insecticidal treatment, and finally undergoes secondary filtration through the rear filtration section of the annular filter 226. Through the combined action of filtration and insecticidal action, the airflow achieves efficient impurity removal and insecticidal effects. Simultaneously, the first and second cleaning mechanisms continuously clean the inner and outer layers of the annular filter 226, ensuring that the annular filter 226 maintains a consistently high-efficiency filtration state, thereby guaranteeing the long-term stable filtration and insecticidal effect of the filter insecticidal device 22.

[0042] In this embodiment, the second air inlet 212 is connected to the air outlet of the refrigeration device for internal circulation of the refrigerated air. Both the first air inlet 211 and the second air inlet 212 are equipped with one-way valves, which interlock to open and close. When the first air inlet 211 opens, the second air inlet 212 automatically closes, creating an external air circulation within the greenhouse; conversely, when the second air inlet 212 opens, the first air inlet 211 automatically closes, creating an internal air circulation within the greenhouse. The two air inlets operate in a selective opening mode, flexibly meeting the air conditioning needs of the greenhouse under different operating conditions.

[0043] like Figure 4 As shown, the transmission unit includes a drive shaft 224 and a driven shaft 225. The internal width of the housing 220 is greater than the width of the air inlet pipe 21. The drive shaft 224 and the driven shaft 225 are rotatably mounted on opposite sides of the inner cavity of the housing 220. The inner ring of the annular filter screen 226 is in transmission cooperation with the drive shaft 224 and the driven shaft 225. This structural arrangement allows the drive shaft 224 and the driven shaft 225 to avoid the direct airflow from the air inlet pipe 21, thus preventing the airflow from interfering with the transmission components.

[0044] like Figure 4As shown, the power unit includes a motor 221, a driving gear 222, and a driven gear 223. The driving gear 222 is fixedly mounted on the output shaft of the motor 221. The driven gear 223 meshes with the driving gear 222 and is fixed to the end of the driving shaft 224. The motor 221 drives the driving gear 222 to rotate, which in turn drives the driven gear 223 and the driving shaft 224 to rotate synchronously. The driving gear 222 is a small gear, and the driven gear 223 is a large gear. The meshing of the large and small gears forms a speed reduction transmission, reducing the output speed of the driving shaft 224, thereby smoothly reducing the operating speed of the annular filter 226.

[0045] like Figure 4 and Figure 5 As shown, the first cleaning mechanism includes a first cleaning brush 228 with a U-shaped cross-section. The bristles of the first cleaning brush 228 elastically abut against the outer layer of the annular filter 226 to achieve dynamic contact cleaning. Specifically, the two ends of the first cleaning brush 228 are respectively tightly abutted against the outer wall of the air inlet pipe 21 on the same side. Through this end-face abutment fit, the assembly gap between the base end of the first cleaning brush 228 and the outer wall of the air inlet pipe 21 is eliminated. The U-shaped structure of the first cleaning brush 228 is adapted to the outer contour of the annular filter 226. During the rotation of the annular filter 226, the bristles rely on elastic deformation to always maintain close contact with the outer layer of the annular filter 226, thereby continuously and stably brushing away the dust, insect carcasses and debris attached to the outer layer of the annular filter 226, effectively improving the reliability of the filter insect killer 22 in removing impurities and killing insects, while ensuring stable airflow in the air duct.

[0046] In this embodiment, a first sealing cover 230 is detachably connected to the outer shell 220 below the first cleaning brush 228. The lower end of the first cleaning brush 228 is rotatably inserted into a socket provided inside the first sealing cover 230. A first collection groove 231 is formed between the side ring wall of the first sealing cover 230 and the socket of the first sealing cover 230. The first collection groove 231 is used to receive and collect impurities, insect carcasses and other dirt swept off the annular filter screen by the first cleaning brush 228. The detachable assembly structure facilitates the disassembly, replacement and maintenance of the first cleaning brush 228. The first collection groove 231 can realize the centralized collection of cleaned dirt, prevent dirt from accumulating inside the outer shell or being re-flying with the airflow, avoid impurities causing secondary pollution to the annular filter screen 226 and airflow channel, and ensure the long-term efficient and stable operation of the filter insect killer.

[0047] Specifically, a first insertion hole is provided at the upper end of the inner shell 220, and a first insertion post is correspondingly provided at the upper end of the first cleaning brush 228. The first insertion post is adapted to be inserted into the first insertion hole. The upper and lower ends of the first cleaning brush 228 are respectively positioned and engaged with the socket of the first sealing cover 230 through the first insertion hole. With the limiting effect of the first sealing cover 230 and the first insertion hole, the axial limiting and circumferential fixing of the first cleaning brush 228 are achieved, ensuring that the first cleaning brush 228 is stably assembled inside the outer shell 220.

[0048] like Figure 5 As shown, the second cleaning mechanism includes a second cleaning brush 229 with a rectangular cross-section. The bristles of the second cleaning brush 229 maintain elastic contact with the inner layer of the annular filter 226. Specifically, bristles are evenly distributed on both the front and rear sides of the second cleaning brush 229 along the airflow direction, and both sides of the bristles form a stable and close contact with the inner layer of the annular filter 226. During the cyclic rotation of the annular filter 226, the bristles on both sides of the second cleaning brush 229 can simultaneously and continuously brush and clean the dust, insect carcasses, and other contaminants attached to the inner layer of the annular filter 226. The bristles on both sides act sequentially on the inner layer of the annular filter 226, forming an uninterrupted dual cleaning effect, thereby improving the cleaning efficiency and thoroughness of the inner layer of the annular filter 226; at the same time, it can prevent contaminants from adhering to and clogging the filter mesh for a long time, ensuring that the annular filter 226 has stable airflow permeability, thereby ensuring the long-term efficient and stable operation of the filtration and insecticidal device.

[0049] like Figure 4 and Figure 5 As shown, the outer casing 220 is detachably equipped with a second sealing cover 232 below the second cleaning brush 229. The lower end of the second cleaning brush 229 is rotatably inserted into a socket inside the second sealing cover 232, and a second debris collection groove 233 is formed between the side ring wall of the second sealing cover 232 and the socket inside the second sealing cover 232. Specifically, a second insertion hole is provided at the upper end of the outer casing 220, and a second insertion post is correspondingly provided at the upper end of the second cleaning brush 229. The second insertion post is adapted to be inserted into the second insertion hole. Through the cooperation of the second insertion hole and the second sealing cover 232, the upper and lower positioning and fixation of the second cleaning brush 229 are achieved. The impurities and insects generated by the second cleaning brush 229 cleaning the annular filter 226 fall into the second debris collection groove 233 under the action of gravity and are collected. The debris in the groove can be quickly discharged by periodically removing the second sealing cover 232, which effectively prevents the accumulation of impurities and secondary pollution, and ensures the long-term efficient and stable operation of the filtration and insect killing device.

[0050] like Figure 6As shown, the annular filter screen includes an outer filter screen 2261, a silver ion-loaded antibacterial meltblown nonwoven fabric 2262, and an inner filter screen 2263 arranged sequentially from the outside to the inside. Specifically, the outer filter screen 2261 is a 40-60 mesh high-toughness PET polyester insect-proof net, the inner filter screen 2263 is an 80-120 mesh high-density PP polypropylene net, and the thickness of the silver ion-loaded antibacterial meltblown nonwoven fabric 2262 is 0.3-0.8 mm. The outer filter screen 2261, the silver ion-loaded antibacterial meltblown nonwoven fabric 2262, and the inner filter screen 2263 are integrated by hot pressing to maintain an annular flexible structure, which can rotate cyclically with the transmission unit. This composite filter achieves primary interception of pests such as fruit flies, aphids, and whiteflies, as well as their eggs, through the outer filter screen. The inner filter screen 2263 performs fine filtration of tiny particles and fungal spores. The silver ion-loaded antibacterial meltblown nonwoven fabric 2262 simultaneously achieves antibacterial and bacteriostatic effects and deep purification. It can effectively block pests, insect eggs, and pathogenic spores from entering the greenhouse through the air intake channel, ensuring a clean and safe growing environment for bayberries inside the greenhouse.

[0051] The intelligent agricultural bayberry growth environment control system of this invention, in the air intake stage, the airflow sequentially passes through the outer filtration section of the composite annular filter to intercept large particles and some pests, and then through the inner filtration section to precisely filter the remaining small impurities and missed pests. Simultaneously, relying on the antibacterial and insecticidal effect of the silver-loaded antibacterial meltblown nonwoven fabric in the filter interlayer, combined with the physical killing effect of the insecticidal lamp inside the filter on the intercepted pests, a dual-killing treatment is achieved for pests and pathogenic microorganisms captured by the inner and outer layers of the filter, constructing a closed-loop purification system for air intake with double-layer physical filtration and dual synergistic insecticidal action. The synergistic linkage between the insecticidal lamp and the composite annular filter significantly improves the thoroughness of pest and pathogenic microorganism elimination, and effectively avoids secondary airflow pollution caused by insect carcasses and impurities, enhancing the comprehensiveness and operational reliability of air intake purification, and creating a clean airflow environment free of pests and pathogens for the growth of bayberry plants in the greenhouse.

[0052] The intelligent agricultural bayberry growth environment control system of this invention relies on a circular rotating filter mechanism, combined with an inner and outer double-sided cleaning mechanism. The outer U-shaped brush eliminates cleaning blind spots through elastic contact, while the inner double-sided brushes form a double sweeping action, achieving continuous cleaning of pollutants on both the inner and outer layers of the circular filter. With a detachable sealing cover and a collection groove, the cleaned insect carcasses and impurities are collected by gravity and easily discharged, preventing pollutants from accumulating and clogging the mesh or being re-entrained by airflow. This structure solves the pain points of traditional filters being prone to clogging and cumbersome to clean, ensuring that the filter maintains stable airflow permeability and filtration accuracy over a long period, thus extending the filter's lifespan.

[0053] The technical solution of the present invention has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
