Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for bean cultivation, specifically to a ventilated and light-transmitting cultivation rack that is beneficial for the prevention and control of bean rust disease. Background Technology
[0002] Common beans, also known as string beans, kidney beans, and jade beans, are annual, twining or nearly erect herbaceous plants belonging to the genus *Phaseolus* of the legume family. They are one of my country's important vegetable crops. Common beans can be divided into three types: vining, semi-vining, and dwarf. Vining beans are indeterminate, with stems reaching 3-5 meters in length. They are climbing, twining in a left-handed manner, and require trellises for cultivation. Dwarf beans are determinate, with an erect main stem and a plant height typically 40-50 cm. When planting vining beans, vine supports are needed. By erecting supports and stakes, the growing space of the beans is expanded, guiding their growth, promoting vigorous development, and increasing fruit yield. In addition, using vine supports for auxiliary support can prevent mechanical damage, provide auxiliary support for the beans, improve their ability to bear their own weight and resist wind and rain, and facilitate field management and the removal of old and yellow leaves. At the same time, the growth of common beans is sensitive to environmental conditions, especially ventilation, light, and humidity control, which directly affect their yield and quality.
[0003] Bean rust is one of the most common and serious fungal diseases in bean cultivation. Its pathogen is *Uromyces appendiculatus* (Pers.) Ung., a basidiomycete rust fungus. This disease is characterized by rapid spread, wide range of damage, and difficulty in control. Specifically: 1. Pathogen and transmission route: *Uromyces appendiculatus* overwinters as teliospores on diseased plant debris. The following spring, when temperatures rise to 15-25℃ and relative humidity exceeds 85%, the rust spreads rapidly. 1. When the teliospores germinate, they produce urediniospores, which are spread by air currents, rain splashes, or agricultural operations (such as pruning and harvesting), entering through the stomata or epidermis of the bean leaves; 2. Symptoms: In the early stage of the disease, small pale yellow spots appear on the upper surface of the bean leaves, which gradually expand into yellowish-brown, nearly circular, rust-like spore masses. After the spore masses rupture, yellowish-brown powder (urediniospores) is released. In the later stage, black teliospore masses form on the underside of the leaves, petioles, and stems; 3. Consequences: The photosynthesis of bean leaves affected by rust is hindered, and the leaves gradually wither and fall off. In severe cases, the entire plant loses its leaves, resulting in poor pod development and deformities, reducing yield by 30%-60%. The quality of diseased pods also declines, failing to meet market demand. At the same time, the rust pathogen easily accumulates in the soil and diseased plant debris, leading to repeated outbreaks of the disease in continuously cropped fields, affecting the long-term cultivation of bean plants.
[0004] Rust disease is prone to outbreaks in high-humidity environments, and chemical control is often used in production, involving multiple sprays of pesticides. Traditional trellis designs cause bean vines to form a closed layer, hindering air circulation and resulting in relative humidity often exceeding 90%. This provides a suitable high-humidity environment for rust fungus germination and spread. Therefore, to reduce bean rust and control pests, we redesigned the bean growing environment, improving the traditional cultivation trellis and optimizing ventilation through structural design. This reduces rust occurrence at its source and lowers reliance on pesticides. Utility Model Content
[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide a ventilated and light-transmitting cultivation rack that facilitates the control of rust disease in beans. This rack is easy to maintain, can be reused multiple times, improves light utilization, and has the technical effect of balancing photosynthesis and rust inhibition, thereby improving the yield and quality of beans.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A ventilated and light-transmitting cultivation frame for controlling bean rust includes climbing vines, vertical support rods, longitudinal connecting rods, and horizontal support rods arranged in a trellis shape. The intersections of the vertical support rods, longitudinal connecting rods, and horizontal support rods are connected by a five-way pipe. Furthermore, the longitudinal connecting rod, the transverse support rod, and the climbing vine are interconnected hollow tubes. A ventilator is installed at the end of the longitudinal connecting rod, and ventilation holes are provided on the side of the longitudinal connecting rod and the transverse support rod facing the bean planting ridge. Several ventilation holes are arranged alternately along the height direction of the climbing vine. The climbing pole consists of a pole head and a pole body. The pole head is screwed into and out of the pole body by threads. The pole head is detachably installed on a five-way pipe joint. The pole body is conical and inserted into the bean planting ridge.
[0007] Furthermore, the outer surfaces of the horizontal support rod, the longitudinal connecting rod, and the climbing vine are all coated with a reflective coating, which is a nano-titanium dioxide-acrylic resin composite coating.
[0008] Furthermore, dustproof and anti-clogging components can be detachably connected to the ventilation holes of the longitudinal connecting rod, the transverse support rod, and the climbing vine. The dustproof and anti-clogging components include an 80-120 mesh nylon filter and an elastic retainer. The elastic retainer is fitted onto the edge of the filter and is fixed by interference fit between the elastic retainer and the wall of the ventilation hole. The filter can be removed separately.
[0009] Furthermore, the outer surface of the climbing pole is coated with an anti-corrosion and insect-proof coating, which is a composite coating of permethrin and epoxy resin.
[0010] Furthermore, it also includes a wind speed adjustment module, which consists of an adjustable speed controller and a wind speed sensor. The wind speed sensor is installed on the side of the horizontal support rod and the longitudinal connecting rod near the bean vines to detect the wind speed inside the frame in real time. The adjustable speed controller is electrically connected to the ventilator and can adjust the ventilator wind speed to different speed levels for the seedling stage, flowering stage, and pod-setting stage according to the feedback signal from the wind speed sensor.
[0011] Furthermore, the connection between the vertical support rod and the horizontal support rod is a curved bend.
[0012] Furthermore, a blade sleeve is installed on the rod body, and a cutting blade facing the outer surface of the rod body is installed on one side of the blade sleeve. A transverse locking rod passes through the rod body and the blade sleeve in the radial direction to lock the two. A cutting groove is provided on the rod body extending along its length direction, and the cutting blade is embedded in the cutting groove and moves.
[0013] The advantages of this utility model compared with the prior art are: 1. This cultivation rack utilizes a hollow tube structure with interconnected longitudinal connecting rods, transverse support rods, and climbing vines. This design drives airflow to form a circulating convection within the rack, directly disrupting the critical high-humidity conditions for rust fungal germination. Simultaneously, the staggered ventilation holes guide airflow directly to the perimeter of the bean planting ridges, reducing condensation on leaf surfaces and lowering the probability of urediniospores invading through stomata / epidermis. This structural improvement replaces some chemical control methods at the environmental regulation level, significantly reducing the frequency of pesticide spraying, meeting the requirements for pollution-free vegetable production, and resolving the dual contradiction between "high humidity inducing disease" and "chemical pollution control."
[0014] 2. This cultivation trellis features a "nano-titanium dioxide-acrylic resin composite reflective coating" on the outer surfaces of its horizontal support rods, longitudinal connecting rods, and climbing vines. This coating diffuses and scatters natural light projected onto the trellis surface, allowing light to penetrate the gaps between the vines and reach the lower leaves, significantly improving the uniformity of light within the trellis. Simultaneously, nano-titanium dioxide can help inhibit the activity of some pathogenic microorganisms under light, indirectly reducing the adhesion ability of rust fungi. This approach solves the problem of "excessive light in the upper layers and insufficient light in the lower layers" in traditional trellises, while also enhancing photosynthesis to promote pod development and reduce the "leaf yellowing and shedding, and yield reduction of 30%-60%" caused by rust disease, thus balancing yield and quality improvement.
[0015] 3. The detachable "80-120 mesh nylon filter + elastic retaining ring" dustproof and anti-clogging component at the air vent can effectively block field weed debris and soil particles from entering the hollow pipe, avoiding airflow obstruction caused by vent blockage; and the interference fit design of the elastic retaining ring allows the filter to be disassembled and cleaned separately without replacing the entire frame, improving maintenance efficiency by more than 60%.
[0016] 4. The "permethrin and epoxy resin composite anti-corrosion and insect-repellent coating" applied to the vine poles not only prevents corrosion of the poles caused by soil and microorganisms, but also repels pests such as aphids and bean pod borers through the slow-release effect of permethrin, preventing wounds on the vines caused by pests from becoming entry points for rust fungi.
[0017] 5. The "wind speed adjustment module (adjustable speed controller + wind speed sensor)" of this cultivation rack can detect the wind speed inside the rack in real time and switch the speed according to the characteristics of different growth stages: low wind speed (0.5-1m / s) is used during the seedling stage to avoid damage to tender vines due to excessive airflow; medium wind speed (1-1.5m / s) is used during the flowering stage to ensure pollen dispersal efficiency while maintaining suitable humidity and reducing flower drop; high wind speed (1.5-2m / s) is used during the pod-setting stage to quickly reduce the humidity of the rack and prevent condensation on the pod surface from inducing diseases. This precise control design solves the problem that traditional racks "cannot adapt to the entire growth stage with a single ventilation intensity," further improving the pod setting rate and pod marketability.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments.
[0021] like Figure 1 — Figure 4The illustrated ventilated and light-transmitting cultivation frame for controlling bean rust includes climbing poles 5, and vertical support poles 1, longitudinal connecting poles 2, and horizontal support poles 3 arranged in a trellis shape. The longitudinal connecting poles and horizontal support poles are connected by a five-way pipe 6, which is made of hot-dip galvanized steel pipe. The length of the horizontal support pole 3 covers the distance between two vertical support poles. The connection between the horizontal support pole 3 and the vertical support pole 1 is made of ABS material with an arc-shaped elbow. The horizontal support pole 3 and the vertical support pole 1 can also be integrally formed into an arched door structure, which can be covered with a transparent greenhouse film to build a bean greenhouse.
[0022] The longitudinal connecting rod 2, the transverse support rod 3, and the climbing vine 5 are interconnected hollow pipes. A ventilator 7 is installed at the end of the longitudinal connecting rod 2. The ventilator is a small axial flow fan (model FA-40, air volume 120m³ / h, power 20W, rated voltage 220V). It is connected to the end of the longitudinal connecting rod through a flange. A 5mm thick silicone sealing gasket is installed between the flanges to prevent air leakage.
[0023] Ventilation holes are provided on the side of the longitudinal connecting rod 2 and the transverse support rod 3 facing the bean planting ridge, and several ventilation holes 50 are staggered along the height direction of the climbing vine 5. The ventilation holes on the longitudinal connecting rod and the transverse support rod are 8mm in diameter, spaced 15cm apart along the length of the pipe, and are only opened on the side facing the bean planting ridge (perpendicular to the ridge surface); the ventilation holes on the climbing vine 5 are 6mm in diameter, staggered along the height direction (the upper and lower holes are offset by 45°), and spaced 10cm apart, to ensure that airflow can reach all layers of the vine.
[0024] The system also includes a wind speed adjustment module, which consists of an adjustable speed controller and a wind speed sensor. The wind speed sensor is installed on the side of the horizontal support rod and the vertical connecting rod near the bean vines to detect the wind speed inside the frame in real time. The adjustable speed controller is electrically connected to the ventilator and can adjust the ventilator speed to different levels for the seedling stage, flowering stage, and pod-setting stage based on the feedback signal from the wind speed sensor. The wind speed sensor is an FS-200 type (measuring range 0-5m / s, accuracy ±0.1m / s, output signal 4-20mA), which is fixed to the side of the horizontal support rod near the vines (10cm away from the vines, 1.2m high) with plastic cable ties. The adjustable speed controller is a TC620 type (12V power supply, supports RS485 communication), installed at a height of 1.5m on the vertical support rod for easy operation. The controller is connected to the ventilator via a 1.5mm² copper core wire, and the wind speed level switching is achieved through a relay. Specific speed parameters can be set as follows: seedling stage (15-25 days after sowing): 0.5-1.0 m / s; flowering stage (26-40 days after sowing): 1.0-1.5 m / s; pod-setting stage (41-60 days after sowing): 1.5-2.0 m / s.
[0025] The climbing pole 5 consists of a pole head 51 and a pole body 52. The pole head 51 is screwed onto the pole body 52 via a threaded connection. The pole head is detachably mounted on a five-way pipe 6 connector. The pole body 52 is tapered and inserted into the bean planting ridge. The pole head is made of PVC (20mm inner diameter, 15cm length, with M18 internal threads on the inner wall), and the pole body is made of Q235 hot-dip galvanized steel pipe (20mm outer diameter, 1.8mm wall thickness, 1.5m total length, tapered at the bottom 20cm with a 1:5 taper for easy insertion into the soil). The pole head and pole body are screwed together, and the length above ground can be adjusted (range 60-100cm).
[0026] In addition, the pole body 52 is telescopic (ordinary telescopic tube structure), which can be lengthened and shortened, making it convenient to install the climbing pole separately without disassembling the longitudinal connecting rod 2 and the transverse support rod 3, facilitating its repeated use during greenhouse planting.
[0027] The outer surfaces of the horizontal support rod 3, the longitudinal connecting rod 2, and the climbing vine 5 are all coated with a reflective coating. The reflective coating is a nano-titanium dioxide-acrylic resin composite coating, with nano-titanium dioxide particles of 20-30nm in diameter, accounting for 15%; acrylic resin accounting for 85%, and a coating thickness of 50-80μm. The coating process is electrostatic spraying, and after spraying, it is dried in an oven at 80-100℃ for 2 hours to ensure adhesion.
[0028] Furthermore, an anti-corrosion and insect-repellent coating can be applied to the outer surface of the climbing vine pole 5. A composite system of permethrin (effective ingredient content 5%-8%) and epoxy resin (E-44 type) is applied to the outer surface of the climbing vine pole, with a thickness of 30-50μm. The coating process is dip-coating, and it is cured at room temperature for 1.5h. It meets the pollution-free requirements in GB / T 19630.1-2021 "Organic Products Part 1: Production", and has a repellency rate of ≥80% against aphids and bean pod borers.
[0029] Dustproof and anti-clogging components 43 are detachably connected to the ventilation holes 50 of the longitudinal connecting rod 2, the transverse support rod 3, and the climbing vine 4. These components include an 80-120 mesh nylon filter and an elastic retainer. The elastic retainer is fitted onto the edge of the filter and secured by an interference fit between the retainer and the wall of the ventilation hole. The filter can be removed independently; during installation, it is simply pressed into the hole wall, and during removal, the retainer can be removed with tweezers. The elastic retainer is embedded in the ventilation hole, with its outer edge flush with the outer wall of the vine.
[0030] A blade sleeve 4 is mounted on the rod body. A cutting blade 40 is mounted on one side of the blade sleeve 4, facing the outer surface of the rod body. A transverse locking rod 44 passes radially through the rod body and the blade sleeve 4 to lock them together. A cutting groove 10 extending along the length of the rod body is provided, and the cutting blade 40 moves within the cutting groove 10. The blade sleeve is fitted seamlessly into the rod body and is not restricted by ventilation holes or dustproof and anti-clogging components when moving up and down.
[0031] The blade sleeve 4 has an integrally formed hollow protruding wall 41 on the side where the cutting blade 40 is installed. This is a non-standard part cast in a mold. A blade holder 42 is located on the inner side (vertical side) of the hollow protruding wall 41. A blade U-shaped groove is located on the side of the blade holder 42 facing the central axis. A fixing bolt passes through the hollow protruding wall 41 in the transverse direction. The cutting blade 40 is trapezoidal and is held in the blade U-shaped groove, with the cutting edge facing downwards. The blade of the cutting blade 41 has bolt holes. The fixing bolt passes transversely through the blade U-shaped groove and bolt holes for detachable installation. Essentially, the lower end of the hollow protruding wall 41 is not closed. The cutting blade 40 is installed by sliding it in from bottom to top. First, the blade tip must be aligned with the cutting groove 10. After sliding in, the fixing bolt 43 passes transversely, locking the blade in the blade U-shaped groove of the blade holder 42. The bolt and nut are then tightened for fixation.
[0032] The lower end of the shaft is equipped with a lower limit ring 8, the diameter of which is larger than the diameter of the blade sleeve 4. The top of the shaft is equipped with an upper limit ring 9 (not exceeding the threaded position of the shaft head), the diameter of which is larger than the diameter of the blade sleeve. Both the upper and lower limit rings are movable and can be directly screwed on, facilitating the installation and replacement of the blade sleeve.
[0033] The assembly of this cultivation rack needs to be completed 5-7 days after the green beans are sown (before the seedlings emerge). The vertical support rod 1, longitudinal connecting rod 2, and horizontal support rod 3 generally form the frame. After laying the greenhouse film and installing the ventilator 7, pay attention to waterproofing. This system can be reused and does not need to be dismantled. Each time, only the climbing pole 5 needs to be erected. During installation, first screw the pole body 52 into the pole head 51. The pole head 51 is then screwed into the five-way pipe 6 through the thread. After installing the blade sleeve 4 and the upper limit ring 9 on the pole body, tighten the pole body to the pole head. Then, stretch the pole body so that its lower end is inserted into the soil of the planting ridge. The spacing of the longitudinal connecting rod and the horizontal support rod is determined according to the green bean planting spacing. When planting green beans, use the fixed-distance bean pointing device to plant at the standard spacing. This way, the climbing pole can be installed in place each time it is erected. Planting at the standard spacing can also increase the yield of green beans.
[0034] Turn on the ventilation fan 7 at different growth stages of the bean vines, and switch between different speeds using the adjustable speed controller. Use an anemometer to measure the wind speed in the vine growth area (50cm away from the climbing pole): 0.8±0.2m / s for the seedling stage, 1.2±0.2m / s for the flowering stage, and 1.8±0.2m / s for the pod-setting stage. Adjust the controller parameters if the deviation exceeds the limit. Check whether the airflow from the ventilation holes is uniform, and reinstall dustproof components where there is blockage.
[0035] This cultivation rack needs to be operated in stages, taking into account the growth characteristics of beans at different growth stages and the requirements for rust disease control: The first stage, the seedling stage (15-25 days after sowing, when the seedlings have 3-4 true leaves). Ventilation control: Turn on the ventilation fan from 9:00-11:00 and 14:00-16:00 daily, switch to the seedling stage setting (0.5-1.0m / s), reduce the humidity inside the frame (control at 75%-80%), and prevent seedlings from growing too tall. Maintenance: Check the dust filter every 7 days. If there are many soil particles or weed debris on the surface, rinse with clean water, dry and reinstall. No cutting knife is needed (if the vines have not climbed to the height where they need to be trimmed).
[0036] The second stage, the flowering period (26-40 days after sowing, the vines begin to bud and bloom). Ventilation control: Turn on the ventilation fan from 8:00-11:00 and 13:00-16:00 daily, and switch it to the flowering period setting (1.0-1.5m / s) to ensure the slight airflow required for pollen dispersal while avoiding high humidity (controlled at 70%-75%) that could cause flower drop. Vines Management: When the vines are too densely wrapped around the climbing vines (spacing < 5cm), loosen the horizontal locking bar, move the blade sleeve up and down along the cutting groove to cut off the excess side branches (keep the main vine and 2-3 side vines), and tighten the locking bar again after cutting to prevent the sleeve from loosening.
[0037] The third stage, the pod-setting stage (41-60 days after sowing, when the pods begin to swell and mature). Ventilation control: Turn on the ventilation fan from 7:00-11:00 and 13:00-16:00 daily, switch to the pod-setting stage setting (1.5-2.0m / s), quickly reduce the humidity of the frame (control at 65%-70%), and inhibit the germination of rust fungus (the suitable humidity for rust fungus is >85%). Fruit protection: Regularly check the verticality of the climbing vines. If they tilt due to wind and rain (deviation > 3°), straighten them in time and compact the soil. Avoid collisions with the ventilator and sensors when harvesting pods to prevent damage to components.
[0038] Phase 4: Post-harvest maintenance (after the pod-setting period ends) Disassembly and cleaning: Remove the ventilator and wind speed adjustment module, and wipe the surface dust with a dry cloth; remove the dust filter, soak it in 50℃ warm water + neutral detergent for 10 minutes, rinse and dry; after pulling the climbing vines out of the soil, clean the dry bean vines and residual soil from the pole, check whether the anti-corrosion coating is damaged, and apply permethrin-epoxy resin composite coating to the damaged areas; Storage: Store each component separately in a dry and ventilated warehouse, avoiding direct sunlight (to prevent coating aging). Vertical and horizontal support rods can be stacked (height ≤ 1.5m to avoid deformation). Recalibrate the wind speed sensor accuracy before the next planting.
[0039] The above-mentioned plan is currently in the experimental stage, with small-scale planting, mainly of green vegetables with low pesticide use (taking cowpeas and green beans as examples). After the experiment is successful, large-scale planting will be carried out, and management and maintenance efficiency needs to be improved.
[0040] The above provides a detailed description of a ventilated and light-transmitting cultivation rack for controlling bean rust disease, as provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
