Description

Technical Field

[0001] This invention belongs to the field of vegetable field pest and disease control technology, and particularly relates to a vegetable field pest and disease control device and method based on UVC, ozone and micro-airflow disturbance. Background Technology

[0002] In the field of vegetable pest and disease control, traditional methods have many drawbacks. Chemical control, as a common method, involves spraying pesticides to suppress pests and diseases. However, long-term reliance on chemical pesticides can lead to a series of serious problems. On the one hand, pests are increasingly developing resistance to pesticides, significantly reducing their effectiveness. To ensure control, farmers often have to increase the amount and frequency of pesticide use, which not only increases production costs but also further exacerbates environmental pollution. On the other hand, pesticide residues seriously threaten food safety and pose a potential risk to consumer health. Simultaneously, the extensive use of chemical pesticides disrupts the soil's ecological balance, affecting soil fertility and microbial communities, which is detrimental to sustainable agricultural development.

[0003] Biological control methods utilize beneficial organisms or their metabolites to control pests and diseases, offering advantages such as environmental friendliness and safety. However, this method is highly dependent on environmental factors; for example, unsuitable conditions such as temperature and humidity can reduce the activity of beneficial organisms, leading to unstable control effects. Furthermore, biological control typically requires a long time to take effect, making it difficult to respond quickly to sudden outbreaks of pests and diseases.

[0004] Existing physical control methods, such as light traps and color sticky traps, are only effective against some pests that are attracted to light or color, resulting in a narrow range of control and an inability to comprehensively control pathogens and other non-phototactic pests. Furthermore, in practical applications, these physical methods often fail to achieve good control results due to the complex environment of vegetable fields, such as dense vegetation and undulating terrain.

[0005] Furthermore, most existing pest control technologies focus solely on eradicating pests and diseases, rarely considering their impact on leafy vegetable growth and quality. Leafy vegetables have short growth cycles and are prone to pest and disease outbreaks, necessitating a technology that can effectively control pests and diseases while also promoting leafy vegetable growth, improving quality, and leaving no residue. This technology must not only solve the problem of pest and disease control but also meet the needs of modern green agriculture, reducing negative environmental impacts and ensuring the quality and safety of agricultural products. Summary of the Invention

[0006] The purpose of this invention is to provide a device and method for controlling pests and diseases in vegetable fields based on UVC, ozone, and micro-airflow disturbance, so as to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following solution: a vegetable field pest and disease control device based on UVC, ozone, and micro-airflow disturbance, comprising: The UVC sterilization and insecticidal mechanism includes a deflection housing and a drive unit for adjusting the deflection angle of the deflection housing. The bottom of the deflection housing is provided with a UVC lamp for sterilization and stimulating the growth of vegetable leaves and a diffuser tube for diffusing ozone into the vegetable field. The micro airflow generating mechanism includes two sets of air ducts disposed on the deflection housing. The two air ducts are respectively located on both sides of the UVC lamp. The two air ducts are connected to the airflow generating component. An airflow guide is disposed in the air duct. The airflow guide is used to blow ozone towards the vegetable field. The moving mechanism includes a top plate and a walking assembly. The deflecting housing is disposed at the bottom of the top plate via a height adjustment assembly, which is used to adjust the height of the deflecting housing above the vegetable field.

[0008] Preferably, the driving component includes a hinge plate, and the two ends of the deflection housing are rotatably connected to the hinge plate through hinge shafts. A second motor is fixedly connected to one side of the hinge plate, and the output shaft of the second motor is fixedly connected to the hinge shaft along the same axis.

[0009] Preferably, a fixing groove is formed at the center of the bottom of the deflection housing along the length of the deflection housing, the diffuser tube is fixedly connected in the fixing groove, two sets of UVC lamps are provided, the two UVC lamps are respectively located on both sides of the diffuser tube, and a plurality of diffuser holes are formed on the side of the diffuser tube away from the deflection housing.

[0010] Preferably, the airflow guide includes an air outlet located on the side of the air duct away from the deflection housing, and an air nozzle is rotatably connected inside the air outlet, the air nozzle being used to guide the direction of airflow.

[0011] Preferably, the airflow generating component includes a fan fixedly connected to the top plate, the air outlet of the fan being connected to the two air ducts through a first air outlet pipe, and an air outlet position adjustment component being provided between the first air outlet pipe and the air ducts.

[0012] Preferably, the air outlet position adjustment component includes a plurality of diffuser covers, each of which is connected to the side of the air duct near the deflection housing. The plurality of diffuser covers are arranged at equal intervals along the length of the air duct. The ends of the plurality of diffuser covers away from the air duct are connected to connecting pipes. The plurality of connecting pipes are connected to the first air outlet pipe. A solenoid valve is connected to the plurality of connecting pipes.

[0013] Preferably, the height adjustment assembly includes two sets of first connecting rods and two sets of second connecting rods. The middle portions of the first connecting rods and the second connecting rods are hinged together. A hinge rod is hinged between one end of each of the two first connecting rods and between one end of each of the two second connecting rods. The two hinge rods are respectively hinged to the top plate and the hinge plate. A sliding rod is rotatably connected between the other ends of each of the two first connecting rods and between the other ends of each of the two second connecting rods. A sliding groove is horizontally formed in the top plate and the hinge plate. The two sliding rods are slidably connected in the two sliding grooves. A moving drive is provided in the top plate, which is used to drive the sliding rods to slide in the sliding grooves.

[0014] Preferably, a cover plate is slidably connected to both ends of the side wall of the diffuser tube, and a lever is fixedly connected to the cover plate for sliding the cover plate around the axis of the diffuser tube. When the two cover plates slide to the first position, a number of diffuser holes on both sides of the diffuser tube are in a ventilated state. When the cover plate slides to the second position, a number of diffuser holes on both sides of the diffuser tube are in a closed state.

[0015] The method for controlling vegetable field pests and diseases based on UVC, ozone, and micro-airflow disturbance includes the following steps: Move the device to the treatment area in the vegetable field, adjust the height between the deflection housing and the vegetable field using the height adjustment component, adjust the irradiation angle of the UVC lamp using the drive component, and adjust the blowing direction of the micro-airflow using the airflow guide component. The UVC lamps and airflow generator are activated, and the walking component moves above the vegetable field. The micro-airflow blows towards the vegetable field, blowing ozone into the field while simultaneously stirring up pathogens on the surface of the vegetables and disturbing and repelling pests. The UVC lamps and ozone work together to kill bacteria and pests.

[0016] Compared with the prior art, the present invention has the following advantages and technical effects: 1. In terms of pest and disease control, 220-250nm UVC can precisely destroy the genetic material of pathogens, exhibiting a powerful killing ability against various bacterial and fungal diseases; simultaneously, it directly acts on the physiological structure of pests, effectively reducing their numbers. Ozone, with its strong oxidizing properties, can naturally diffuse within the vegetable field, penetrating deep into all parts of the plant and covering areas that UVC irradiation might miss, achieving thorough pest and disease control. Furthermore, micro-airflow disturbances not only accelerate ozone diffusion but also expose pathogens and pests hidden in the leaves, greatly improving overall control efficiency. Compared to traditional control methods, this approach can more quickly and thoroughly control the spread of pests and diseases, significantly reducing the damage caused to leafy vegetables.

[0017] 2. From an environmental perspective, this invention completely eliminates the use of chemical pesticides, preventing pesticide residues from polluting the soil, water, air, and other ecological environments. After UVC irradiation and ozone disinfection, no harmful residues are left behind, and the ozone eventually decomposes into oxygen, effectively maintaining the balance of the vegetable field ecosystem. This aligns with the development concept of green and sustainable agriculture and makes a positive contribution to protecting the ecological environment.

[0018] 3. In terms of promoting the growth and improving the quality of leafy vegetables, short-term and appropriate doses of UVC irradiation stimulate the secondary metabolic process of leafy vegetables, prompting them to synthesize more secondary metabolites that are beneficial to the human body, such as abundant vitamins, minerals and antioxidants, thus significantly improving the nutritional value of leafy vegetables.

[0019] 4. Furthermore, this invention also has the advantage of reducing labor costs in practical applications. Traditional pest and disease control methods often require a large amount of manual labor for pesticide spraying, equipment setup and operation, etc. In contrast, this invention, with its automated control system and mobile mechanism, only requires a small number of personnel for initial parameter setting and remote monitoring, greatly reducing labor input, lowering labor costs, and improving the economic efficiency of agricultural production. It provides a highly efficient and economical pest and disease control solution for modern agricultural production.

[0020] 5. In summary, the vegetable field pest and disease control technology of the present invention has outstanding advantages in many key aspects such as pest and disease control effect, environmental benefits, improvement of leafy vegetable quality and cost control, which effectively promotes the development of vegetable field planting towards a green, efficient and sustainable direction.

[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] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-5 This invention provides a vegetable field pest and disease control device based on UVC, ozone, and micro-airflow disturbance, comprising: The UVC sterilization and insecticidal mechanism includes a deflection housing 4 and a drive component for adjusting the deflection angle of the deflection housing 4. The bottom of the deflection housing 4 is equipped with a UVC lamp 7 for sterilization and stimulating the growth of vegetable leaves and a diffuser tube 9 for diffusing ozone into the vegetable field. The micro airflow generating mechanism includes two sets of air ducts 5 set on the deflection housing 4. The two air ducts 5 are located on both sides of the UVC lamp 7. The two air ducts 5 are connected to the airflow generating component. An airflow guide is set in the air duct 5. The airflow guide is used to blow ozone towards the vegetable field. The moving mechanism includes a top plate 1 and a walking assembly. The deflection housing 4 is set at the bottom of the top plate 1 by a height adjustment assembly, which is used to adjust the height of the deflection housing 4 above the vegetable field. The airflow generating assembly is set on the top plate 1.

[0026] The main function of the driving component is to adjust the deflection angle of the deflection housing 4 so that the UVC lamp 7 can irradiate the vegetable field at an appropriate angle. The main function of the UVC lamp 7 is to emit UVC light with a wavelength of 220-250nm, covering a certain area of ​​the vegetable field for efficient sterilization and pest control, while also generating ozone. The main function of the diffuser 9 is to ensure that ozone is evenly released in the area below the deflection housing 4. The main function of the airflow generating component is to generate a gentle airflow. The main function of the airflow guide component is to guide the airflow, which can be directed towards the leafy vegetable plants. The main function of the walking component is to move the entire device, allowing it to move freely in the vegetable field. Overall, this invention utilizes the characteristics of UVC's ability to efficiently kill various bacteria and fungi, and ozone's ability to naturally diffuse in the vegetable field and penetrate deep into all parts of the plant for sterilization. Through the synergistic sterilization and pest control of ozone and UVC, the overall control efficiency is greatly improved. At the same time, the innovative integration of a micro-airflow generating mechanism enhances the effect of raising pathogens and removing pests from the leaves, thereby improving the sterilization effect of UVC.

[0027] To further optimize the solution, in this embodiment, UVC lamp 7 is the core control equipment, employing 220-250nm UVC LED lamps. This specific wavelength range of UVC has highly efficient bactericidal and insecticidal capabilities, directly damaging the DNA or RNA structure of pathogens, rendering them unable to reproduce and survive. It has a significant killing effect on common fungal and bacterial diseases in vegetable fields. Simultaneously, UVC irradiation can damage the cell membranes and nervous systems of pests, directly killing them or interfering with their normal growth and development, effectively controlling pest populations.

[0028] Meanwhile, short-term, high-dose 220-250nm UVC irradiation has a positive stimulating effect on leafy vegetables. It can promote cell division and elongation, resulting in larger, thicker leaves and increased photosynthetic area, thus improving yield. Simultaneously, UVC irradiation can stimulate secondary metabolic processes in leafy vegetables, prompting them to produce more secondary metabolites, such as vitamins, minerals, and antioxidants, thereby enhancing their nutritional value and taste, and meeting consumer demand for high-quality agricultural products.

[0029] Meanwhile, the ozone diffused from diffuser tube 9 has strong oxidizing properties and can be used as a highly efficient bactericide and insecticide. It can naturally diffuse in the air, penetrating deep into every corner of the leaves, crevices between plants, and soil surfaces—areas where UVC radiation may be ineffective—achieving comprehensive and thorough pest and disease control. Ozone not only kills exposed pathogens and pests but also inhibits and kills pathogens hidden inside plants or in the soil.

[0030] Finally, a micro-airflow disturbance mechanism is introduced. The micro-airflow guided by the airflow guide not only promotes faster and more even diffusion of ozone in the vegetable field, expanding the range of ozone's effect and enhancing its control effect, but also lifts pathogens attached to the leaf surface, exposing pathogens that are not easily exposed to UVC radiation, such as those hidden in leaf folds and on the back of the leaf. At the same time, it can also cause some pests that rely on the protection of the leaves to detach from the leaves, making them more susceptible to the effects of UVC and ozone, further improving the efficiency of pest and disease control. In addition, the micro-airflow disturbance helps improve the air circulation in the vegetable field, creating a more suitable growth environment for leafy vegetables and reducing the probability of disease occurrence caused by excessive humidity or poor air circulation.

[0031] The scheme was further optimized by installing a control system on the top plate 1. The main function of the control system is to adjust the UVC irradiation time, intensity, ozone generation, and wind speed and running time of the UVC lamp 7.

[0032] The scheme is further optimized. The driving component includes a hinge plate 3. The two ends of the deflection housing 4 are rotatably connected to the hinge plate 3 through hinge shafts. A second motor 21 is fixedly connected to one side of the hinge plate 3. The output shaft of the second motor 21 is coaxially fixedly connected to a hinge shaft.

[0033] like Figure 2 and Figure 3 As shown, the control system controls the second motor 21 to deflect at a certain angle, thereby driving the deflection housing 4 to deflect around the hinge shaft, which in turn causes the UVC lamp 7 at its bottom to deflect, flexibly adjusting the irradiation angle to adapt to the height of the leafy vegetables at different growth stages and the terrain changes of the vegetable field. For example, in the early stage of leafy vegetable growth, the irradiation angle of the UVC lamp 7 can be appropriately lowered to concentrate the irradiation on the bottom of the plant; as the leafy vegetables grow taller, the irradiation angle of the UVC lamp 7 is adjusted accordingly to ensure that the entire leafy vegetable is effectively irradiated.

[0034] In a further optimized design, a fixing groove 8 is provided at the bottom center of the deflection housing 4 along the length of the deflection housing 4, and the diffuser tube 9 is fixedly connected in the fixing groove 8. Two sets of UVC lamps 7 are provided, with the two UVC lamps 7 located on both sides of the diffuser tube 9 respectively. Several diffuser holes 10 are provided on the side of the diffuser tube 9 away from the deflection housing 4.

[0035] like Figure 2 As shown, in this embodiment, the diffuser 9 is placed in the middle of the deflection housing 4, which allows the diffuser 9 to be appropriately far away from the air duct 5, ensuring that ozone diffuses fully and evenly at the bottom of the deflection housing 4, and avoiding the influence of the micro-airflow in the air duct 5 on the diffusion of ozone.

[0036] Further optimization of the design includes an air outlet located on the side of the air duct 5 away from the deflection housing 4, with an air nozzle 6 rotatably connected inside the air outlet. The air nozzle 6 is used to guide the direction of airflow.

[0037] like Figure 2 As shown, the air outlet 6 deflects within the air outlet, and after adjusting the angle of the deflecting housing 4, the direction of the micro-airflow can be independently adjusted so that the micro-airflow can be directed towards the leafy vegetable plants. At the same time, the airflow guiding function can adapt to different vegetable ridge directions and plant layouts.

[0038] Further optimization of the scheme: the airflow generating component includes a fan 11 fixedly connected to the top plate 1. The air outlet of the fan 11 is connected to two air ducts 5 through a first air outlet pipe 14. An air outlet position adjustment component is provided between the first air outlet pipe 14 and the air duct 5.

[0039] like Figure 3 As shown, the control system can control the wind speed of the fan 11 according to actual needs. For example, if the wind speed is increased appropriately, the effect of blowing up pathogens and removing pests from the leaves can be enhanced.

[0040] The scheme is further optimized. The air outlet adjustment component includes several diffuser covers 27. The several diffuser covers 27 are respectively connected to the side of the air duct 5 near the deflection housing 4. The several diffuser covers 27 are arranged at equal intervals along the length of the air duct 5. The end of the several diffuser covers 27 away from the air duct 5 is connected to a connecting pipe 28. The several connecting pipes 28 are respectively connected to the first air outlet pipe 14. The several connecting pipes 28 are connected to a solenoid valve 29.

[0041] like Figure 5 As shown, three or more diffuser covers 27 can be connected to the air duct 5. By controlling the opening and closing of each solenoid valve 29 through the control system, the air outlet point of the air duct 5 can be controlled to adapt to different plant layouts, avoid excessive air blowing to unplanted areas, and improve air outlet efficiency.

[0042] Further optimization of the scheme: the height adjustment component includes two sets of first connecting rods 18 and two sets of second connecting rods 30. The middle part of the first connecting rod 18 is hinged to the middle part of the second connecting rod 30. A hinge rod 26 is hinged between one end of the two first connecting rods 18 and between one end of the two second connecting rods 30. The two hinge rods 26 are respectively hinged to the top plate 1 and the hinge plate 3. A sliding rod 20 is rotatably connected between the other ends of the two first connecting rods 18 and between the other ends of the two second connecting rods 30. A sliding groove 19 is horizontally opened in the top plate 1 and the hinge plate 3 respectively. The two sliding rods 20 are slidably connected in the two sliding grooves 19 respectively. A moving drive component is provided in the top plate 1. The moving drive component is used to drive the sliding rod 20 to slide in the sliding groove 19.

[0043] In a further optimized design, the moving drive component includes a first motor 16 fixedly connected within the top plate 1. The output shaft of the first motor 16 is coaxially fixedly connected to a lead screw 17. The lead screw 17 passes through a sliding rod 20 located in the top plate 1 and is connected to the sliding rod 20 in the top plate 1 via a threaded transmission.

[0044] like Figure 3 As shown, when it is necessary to lower the height of the deflection housing 4, the control system can control the first motor 16 to drive the lead screw 17 to rotate. Through threaded transmission, the sliding rod 20 moves towards the hinge rod 26, reducing the angle between the first connecting rod 18 and the second connecting rod 30, thus pushing the deflection housing 4 downward. Controlling the first motor 16 to rotate in the opposite direction will raise the deflection housing 4. Adjusting the height of the deflection housing 4 can prevent damage to the leafy vegetables during movement.

[0045] To further optimize the design, the first air outlet duct 14 and the connecting duct 28 are connected by a flexible hose or a corrugated pipe to ensure that the deflection housing 4 can be freely adjusted up and down within a certain range.

[0046] In a further optimized design, cover plates 24 are slidably connected to both ends of the sidewall of the diffuser tube 9. A lever 25 is fixedly connected to the cover plate 24 for sliding around the axis of the diffuser tube 9. When the two cover plates 24 slide to the first position, several diffuser holes 10 on both sides of the diffuser tube 9 are in a ventilated state. When the cover plates 24 slide to the second position, several diffuser holes 10 on both sides of the diffuser tube 9 are in a closed state.

[0047] like Figure 4 As shown, when the width of the vegetable field is narrow, the operator can use the lever 25 to move the cover plate 24 below the diffuser tube 9, i.e., to the second position, blocking the diffuser holes 10 in that area. This ensures that ozone is released only from the middle of the diffuser tube 9, preventing ozone waste. Similarly, by pushing the lever 25 upwards to reset the cover plate 24 to the first position, all diffuser holes 10 can release ozone.

[0048] The design is further optimized so that the walking component includes a bracket 22 that is vertically fixed to both sides of the bottom of the top plate 1, and a walking wheel 23 is provided at the bottom of the two brackets 22 respectively.

[0049] like Figure 1 As shown, in this embodiment, the walking wheel 23 can be combined with an electric drive mechanism to form a wheeled mobile platform, giving the device good mobility and enabling it to move freely in vegetable fields and adapt to different terrains.

[0050] The method for controlling vegetable field pests and diseases based on UVC, ozone, and micro-airflow disturbance includes the following steps: Move the device to the treatment area in the vegetable field, adjust the height between the deflection housing 4 and the vegetable field using the height adjustment component, adjust the irradiation angle of the UVC lamp 7 using the drive component, and adjust the blowing direction of the micro-airflow using the airflow guide component. Activate the UVC lamp 7 and airflow generating component, move the walking component above the vegetable field, and blow micro-airflow towards the vegetable field, blowing ozone into the vegetable field while stirring up pathogens on the surface of the vegetables and disturbing and repelling pests. The UVC lamp 7 and ozone work together to kill bacteria and pests.

[0051] In this embodiment, the UVC dose is set to 10–30 mJ / cm²; the ozone concentration is 1–2 ppm, the frequency is 20–30 s / time; and the micro-airflow velocity is 0.3–0.6 m / s.

[0052] After the task is completed, the walking component moves the device to the designated position and waits for the next task instruction.

[0053] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0054] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
