[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figure 1 As shown, a seedling antifreeze device for forest cultivation according to this application includes a chassis 1, a support rod 2, an insulation shell 3, and an isolation net 4.

[0028] The base plate 1 is used to fix the entire device and is in direct contact with the soil. Multiple drainage holes are provided at the bottom of the base plate 1 to enhance drainage performance and prevent root rot caused by waterlogging. Each drainage hole is evenly distributed on the surface of the base plate 1 to ensure drainage efficiency and uniformity. Through a scientifically designed drainage hole layout, the number of drainage holes is no less than 5 per square centimeter. This arrangement not only helps excess water to drain away promptly but also ensures dryness within the device during the rainy season.

[0029] Support rod 2 is located above chassis 1. Its function is to support the insulation shell 3 and securely connect it to chassis 1 to ensure the stability and integrity of the structure. Support rod 2 is rigidly connected to chassis 1 by multiple bolts, making the entire structure more robust and durable, and able to withstand the effects of changes in the external environment. In some complex environments, this structure provides effective support.

[0030] The insulation shell 3 is fitted around the seedlings, forming a relatively closed insulation chamber that protects and insulates the seedlings. Ventilation holes are located at the bottom of the insulation shell 3, their positions matching the drainage holes on the base plate 1. This ensures that water entering from the outside can drain directly to the ground, maintaining a suitable temperature and humidity environment and effectively ensuring good aeration and drainage of the soil beneath the seedlings, preventing root hypoxia. The ventilation hole density is at least 10 holes per square centimeter.

[0031] To prevent soil from leaking out of the insulation chamber through the vents and to maintain root ventilation, an isolation net 4 is installed at the bottom of the insulation shell 3. The isolation net 4 is made of stainless steel with a certain degree of flexibility and corrosion resistance, and its thickness ranges from 0.1 to 0.3 mm, allowing it to be used for a long time without being corroded or damaged; at the same time, the mesh size of the isolation net 4 is selected from 1 to 3 mm.

[0032] Additionally, a fixing strap 5 is installed around the upper edge of the insulation shell 3 to securely fix the shell to the support rod. The fixing strap 5 wraps around the top of the insulation shell 3 and is locked around the support rod 2 using a quick-release hook and loop structure, further ensuring the overall structural stability. This fixing mechanism allows users to quickly disassemble the equipment without damaging the main components and facilitates routine inspection and maintenance. In another embodiment, such as... Figure 1 As shown, the fixing strap 5 can also be directly connected between the insulation shell 3 and the support rod 2.

[0033] Specifically, in this application, the chassis 1 is typically made of high-strength non-metallic composite materials such as polypropylene with good water permeability. It is precisely machined and shaped using a CNC machine tool to ensure water permeability without compromising mechanical strength. The selection and installation of other accessories also require consideration of material compatibility and their corresponding functional performance.

[0034] The key design feature of this device is preventing oxygen deficiency in the seedling roots due to excessive sealing. Since insulation often involves limited air circulation, the proper arrangement of holes (including drainage and ventilation holes) in both the upper and lower sections is crucial. The ventilation holes ensure a continuous flow of fresh air into the soil, supplying oxygen to the plant roots, while the multiple loosely arranged small holes in the base plate 1 help moisture dissipate to the ground.

[0035] In one embodiment, further reference Figure 2 The base 1 of this application, a seedling antifreeze device for forest cultivation, is used to fix the entire device and contact the soil. The bottom of the base 1 is designed with multiple permeable holes to enhance drainage performance and prevent water accumulation at the bottom of the device. The diameter of the permeable holes is between 2 and 5 mm, and the spacing between the holes is no more than 5 mm. This design ensures the permeability and aeration of the soil, thereby maintaining suitable environmental conditions for seedling growth. Specifically, the permeable holes not only allow excess water to drain quickly but also provide the necessary oxygen supply to the plant roots, optimizing the soil microenvironment.

[0036] In one technical implementation, the permeable holes are directly machined onto the bottom of the chassis 1 using precision manufacturing processes such as drilling or laser cutting. Through a reasonable layout design, ensuring the density of permeable holes per unit area is not less than a set value, good drainage and aeration functions are guaranteed, effectively preventing soil compaction and seedling root rot caused by excessive moisture. During installation, the support rod 2 is fastened to the chassis 1 with multiple bolts, and the permeable holes on the chassis 1 must precisely correspond to the aeration holes at the bottom of the insulation shell 3 to ensure normal air and moisture flow. Furthermore, to prevent soil from entering the insulation chamber through the aeration holes, an isolation net 4 is installed above the aeration holes, made of stainless steel with a thickness between 0.1 and 0.3 mm, and its aperture controlled within the range of 1 to 3 mm. This ensures both permeability and prevents external debris from interfering with the internal environment of the insulation chamber.

[0037] In one embodiment, the height ratio of the support rod 2 to the insulation shell 3 of the seedling antifreeze device for forest cultivation is set to 1:5 to 1:2. This specific ratio is designed to ensure that the insulation shell 3 stably supports and effectively protects the seedling roots from low temperatures. This design, by adjusting the height of the support rod 2 to accommodate seedlings at different growth stages and of different species, ensures that the seedling roots are under optimal protection conditions, avoiding damage or freezing of seedlings due to unsuitable device height.

[0038] Specifically, support rod 2 is securely installed above chassis 1, primarily serving a structural support function. It is firmly connected to chassis 1 via multiple bolts, enhancing the overall structural reliability. The insulation shell 3 is fitted around the seedlings, forming a closed, insulated chamber. Ventilation holes are located at the bottom, aligned with the drainage holes on chassis 1, ensuring proper soil aeration and drainage.

[0039] For example, to achieve the above-mentioned ratio requirements, an adjustable support rod 2 can be selected. By adjusting its length, the ratio of the support rod 2 to the insulation shell 3 can be maintained between 1:5 and 1:2. The fixing strap 5 is wrapped around the upper part of the insulation shell 3 and is fixedly connected to the support rod 2 through a hook and loop structure, further enhancing the stability of the insulation shell 3 and enabling it to function effectively in various environments, ensuring the healthy growth of seedlings while preventing the risk of root frost damage.

[0040] In one embodiment, a moisture-proof pad 6 is wrapped around the connection between the support rod 2 and the chassis 1 of a seedling antifreeze device for forest cultivation according to this application (see...). Figure 1The moisture-proof mat 6 is made of waterproof material. It is installed on the outer edge of the connection between the support rod 2 and the base 1 to ensure that moisture cannot seep upwards through the gaps between them. This effectively prevents moisture from entering and affecting the seedling root environment, ensuring soil dryness and providing more suitable conditions for seedling growth. This design is particularly suitable for humid environments, further enhancing the adaptability of the device to various weather conditions.

[0041] To ensure the moisture-proof mat 6 effectively isolates moisture, it is made of waterproof material and is installed tightly and securely around the connection area between the bottom of the support rod 2 and the chassis 1. For example, materials such as rubber or polyvinyl chloride with excellent flexibility and abrasion resistance can be selected to meet the needs of long-term use and facilitate replacement and maintenance. During construction, precise measurements of both components are required, and the specifications of the moisture-proof mat 6 must be adjusted according to the actual situation to ensure a good fit and seal, maintaining good overall stability of the entire structure.

[0042] In one embodiment, further reference Figure 3 This application discloses a seedling antifreeze device for forest cultivation. The upper end of the insulated shell 3 is equipped with a movable cover 10. The cover 10 is made of a transparent material and has multiple ventilation slots 7 on its surface to enhance air circulation inside the insulated shell 3 and ensure light penetration. Specifically, this transparent material can be high-transmittance plastic or glass to fully utilize sunlight to promote seedling growth. In this way, good air convection is ensured without affecting light penetration, effectively maintaining temperature and humidity levels. In certain environments, such as when there are large temperature differences between day and night in spring, this design can significantly improve the seedlings' ability to resist cold.

[0043] The cover 10 and the insulation shell 3 are connected by a simple and reliable method, namely, by using a rotating buckle or other quick-connect fittings to achieve practicality and ease of operation. Users can easily open or close the cover 10 to adapt to weather changes and the needs of different seedling stages. In addition, the ventilation slots 7 are scientifically laid out and have reasonable openings, which prevents rainwater from entering directly while maximizing airflow exchange.

[0044] In a specific implementation, for example, a suitable transparent engineering plastic is selected as the raw material for the cover 10, and it is manufactured using injection molding. For the molding of the ventilation slot 7, the corresponding shape can be pre-set in the mold to ensure its structural stability, aesthetics, and practicality. Then, the cover 10 is installed onto the top of the insulation shell 3 using rotating buckles or elastic locks, ensuring convenient, safe, and reliable installation. These detailed design features make the device more flexible and applicable, meeting the needs of diverse usage environments.

[0045] In one embodiment, reference Figure 3In this application, a layer of filter soil mesh 8 is provided above the isolation net 4 of a seedling antifreeze device for forest cultivation. The filter soil mesh 8 is installed directly above the isolation net 4, and the two together prevent soil from leaking out of the insulation chamber while ensuring good air permeability inside. Specifically, this layer of filter soil mesh 8 is adjacent to the isolation net 4 and covers the entire bottom area of ​​the insulation shell 3.

[0046] The filter mesh 8 is made of finely woven nylon filaments, and the selection and weaving method of the nylon filaments ensure that its pore size is less than 1 mm. This fine structure not only effectively blocks larger soil components such as silt particles from passing through, but also allows air molecules to circulate freely, maintaining a well-ventilated environment within the chamber and thus providing healthy growth conditions for the seedling roots. Furthermore, because the filter mesh 8 is located above the isolation mesh 4, it maintains good water permeability and air permeability even under pressure changes caused by rain or other external forces, further enhancing the overall stability of the device.

[0047] For example, in practical applications, the filter screen 8 can be fixed to the perimeter of the isolation net 4 using elastic clips. This method not only facilitates the installation and removal of the filter screen 8 but also prevents it from loosening due to prolonged use, thus maintaining its functional effectiveness and reliability. When it is necessary to clean or replace the filter screen 8, the old screen can be quickly removed and a new screen installed; the operation is simple and does not affect the working status of other components.

[0048] In one embodiment, the width of the fixing strap 5 in the seedling antifreeze device for forest cultivation according to this application is set to 3-5 cm. This design takes into account both ease of use and structural stability to accommodate different seedling sizes. This width provides sufficient contact area, allowing the fixing strap 5 to tightly wrap around the upper area of ​​the outer side of the insulation shell 3. Through the appropriate selection of materials, such as polymer materials with good flexibility and sufficient strength, the fixing strap 5 can not only withstand a certain amount of tensile force but also adapt to minor deformations caused by external environmental factors.

[0049] Meanwhile, to further ensure the effective function of the fixing strap 5 and enhance its fit with the support structure, anti-slip textures are provided on its surface. These fine and regularly arranged raised textures increase the coefficient of friction, significantly reducing the relative displacement tendency between the devices when encountering wind or external disturbances. This helps ensure that the fixing strap 5 firmly connects the insulation shell 3 and the support rod 2 throughout the entire period of use, maintaining a tight bond and preventing the risk of loosening or falling off, thereby ensuring the stability and protective function of the entire antifreeze system.

[0050] For example, the fixing strap 5 can be manufactured directly using a precision mold pressing process, producing a product that meets standard width and anti-slip requirements. During installation, the fixing strap 5 is wrapped around the upper part of the insulation shell 3 and connected and fixed to the support rod 2 that penetrates the top section using a specially designed mechanical structure such as fasteners. This process should be simple and quick to operate and ensure assembly quality to facilitate subsequent normal maintenance and replacement.

[0051] Return to reference Figure 1 In one embodiment, a baffle 9 is provided on the edge of the base 1 of the seedling antifreeze device for forest cultivation according to this application. The baffle 9 is evenly distributed along the edge of the base 1. This design not only effectively prevents water inside the base 1 from overflowing from the edge, but also guides excess water to drain quickly, enhancing the overall drainage performance of the device. Specifically, the peripheral baffle 9 is tightly connected to the base 1, preventing water leakage and ensuring that excess water is effectively treated at the contact point between the base 1 and the soil. Through this design, damage to the seedling roots caused by water accumulation in the base 1 is avoided, ensuring that the seedlings develop in a relatively dry and suitable growing environment.

[0052] For example, the base 1 is a flat circular or square disc, and the baffle 9 is a vertical plate-like structure surrounding the entire boundary of the base 1. The baffle 9 can be fixed to the base 1 by welding, bonding, or other suitable mechanical connection methods to ensure the sealing and firmness between the baffle 9 and the base 1. The height of the peripheral baffle 9 should be moderate, generally not exceeding a few centimeters, sufficient to block water accumulating on the base 1 without affecting the function of other components such as the insulation shell 3. To facilitate drainage, small drainage holes can be opened at the bottom of the baffle 9 to allow excess water to flow smoothly back into the soil without accumulating. In addition, the material of the baffle 9 must have good waterproof and corrosion-resistant properties, such as plastic or corrosion-resistant metal materials. This configuration can ensure the long-term reliable operation of the entire seedling antifreeze device, while effectively improving water management efficiency.

[0053] In one embodiment, the diameter of the base 1 of the seedling antifreeze device for forest cultivation is larger than the bottom diameter of the insulation shell 3, thereby increasing the contact area with the soil. This design, by increasing the size of the base, improves the stability of the entire antifreeze device when placed on the ground while ensuring sufficient structural strength, avoiding the adverse effects on seedlings caused by displacement due to wind or animal contact. To ensure good aeration and drainage, this feature further considers the coordination between the base 1 and the bottom of the insulation shell 3. The enlarged base 1 can more effectively collect and guide water to disperse around it, allowing excess irrigation water or other water sources to be quickly discharged from the multi-point distributed small permeable holes. While simultaneously meeting the requirements of stability and environmental friendliness, the increased effective working area of ​​the base 1 also allows for better soil gas exchange conditions, promoting healthy root development.

[0054] For example, to ensure that the chassis 1 has a large diameter and can be well fixed and tightly connected to the support rod 2, a large-sized circular stainless steel chassis 1 can be manufactured by machining. The support rod 2 is vertically mounted on its upper plane, while the insulation shell 3 is fitted over the support rod 2, which is fixed by bolts. The outer extension of the chassis 1 extends beyond the bottom edge of the insulation shell 3 by a certain distance, which is set according to the actual application scenario. Specifically, the water permeable holes on the chassis 1 and the air permeable holes at the bottom of the insulation shell 3 are precisely drilled to ensure the connectivity between the upper and lower layers, and an isolation mesh 4 is used to cover the upper side of these through holes to prevent impurities from entering the internal space. This construction scheme ensures that all components meet the requirements of the advantages brought by the size difference without compromising their functionality.

[0055] In practical operation, when this device is used, the base plate 1 is fixed in the soil around the seedling, ensuring contact between the base plate 1 and the soil and providing a stable foundation. Multiple drainage holes at the bottom of the base plate 1 enhance drainage performance, preventing water accumulation and root rot. A support rod 2 is installed above the base plate 1 and fixedly connected to it with bolts, supporting the insulation shell 3. The insulation shell 3 is fitted around the seedling, forming an internal insulation chamber that effectively resists low temperatures and protects seedling growth. Ventilation holes at the bottom of the insulation shell 3 ensure soil aeration and water permeability; these ventilation holes correspond to the drainage holes on the base plate 1. An isolation net 4 is located above the ventilation holes to prevent soil leakage from the insulation chamber while maintaining good ventilation for the roots. A fixing strap 5 is wrapped around the upper part of the insulation shell 3 and fixedly connected to the support rod via a hook-and-loop structure, ensuring the insulation shell 3 is stable and not easily damaged by external forces. The drainage holes on the base plate 1 are distributed at a density of no less than five per square centimeter, and the ventilation holes on the insulation shell 3 are distributed at a density of no less than ten per square centimeter. This design ensures sufficient air circulation and good water permeability. The isolation net 4 is made of stainless steel with a thickness of 0.1 to 0.3 mm and a pore size of 1 to 3 mm. While ensuring water permeability, it effectively prevents soil from entering the insulation chamber, thereby providing an excellent microenvironment to promote the healthy growth of seedlings.
