Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology. Background Technology

[0002] In tobacco cultivation, hilling is a core agronomic measure aimed at improving the growth quality and stress resistance of tobacco plants by optimizing the soil environment.

[0003] After the tobacco plants enter their growth period (mostly from the compacted to vigorous growth stage), further hilling is necessary, which involves mounding the soil between the rows up to the base of the stem. This process not only strengthens the plants and prevents lodging (especially important for tall varieties), but also stimulates the growth of adventitious roots at the base of the stem, expanding the nutrient absorption range and improving the plant's efficiency in utilizing water and minerals. Hilling is often combined with topdressing to reduce fertilizer loss by covering it, while simultaneously suppressing weed growth and maintaining soil moisture. Care should be taken to avoid damaging the root system by covering the soil too thickly at once, and the hilling height is usually 5-10 cm above the base of the stem. The effectiveness of these two measures is significantly affected by climate, soil type, and variety characteristics. For example, deep-rooted flue-cured tobacco varieties require more attention to the thickness of the ridges, while windy and rainy areas need to strengthen the lodging prevention capabilities of the hilling. Overall, the scientific application of ridge-making and hilling techniques can significantly improve the microenvironment in tobacco fields, laying the foundation for high-quality and high-yield production.

[0004] However, current tobacco production often uses plastic film mulching. During the soil-building process, the plastic film can interfere with the soil-building operation, requiring manual cutting or lifting, which is time-consuming and not conducive to mass production. Moreover, during the soil-building process, soil can easily be scattered into the tobacco leaves, which can also damage the tobacco plants and affect their growth. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable protective device for inter-row cultivation of tobacco leaves in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A retractable protective device for inter-row cultivation of tobacco includes a plastic film installed along the length of the tobacco ridges, several supporting anchors symmetrically distributed along the length of the tobacco ridges, each supporting anchor having a groove at its upper end, and a wire-laying mechanism and a telescopic wire assembly at both ends of the tobacco ridge. The wire-laying mechanism includes a support platform at each end of the tobacco ridge, a wire-laying shaft on the support platform, and the telescopic wire assembly sleeved on the wire-laying shaft. The two long sides of the plastic film are provided with reinforcing cables, and the telescopic wire assembly is provided with a traction component. The movement trajectory of the telescopic wire assembly passes through the groove, and a connecting member is provided between the telescopic wire assembly and the reinforcing cable.

[0008] The above-described scheme utilizes the slots of the supporting anchor rods to guide the movement trajectory of the telescopic cable assembly. Combined with the reinforcing cables at the edge of the mulch film, it forms an adjustable coverage area. During hilling, the telescopic cable assembly is laid out through the traction component and embedded into the slots. The reinforcing cables on the mulch film are fixed to the telescopic cable assembly via connectors, thereby lifting the mulch film on both sides of the tobacco plant. The lifted mulch film covers the tobacco, preventing soil clods from entering the tobacco plant during hilling, reducing damage to the plants, and avoiding workers trampling on the ridges. After hilling, the lifted mulch film can be re-laid on the surface. Compared to manual mulching, this process reduces labor intensity, standardizes operations, and aligns with the trend of mechanized farming. The overall design directly serves the core objectives of soil moisture retention and warming after ridging, while reserving space for the development of adventitious roots at the stem base during the hilling stage.

[0009] Furthermore, the traction assembly includes a traction rod, which is a multi-section telescopic structure. The end of the traction rod is provided with a hook, and the end of the telescopic cable assembly is provided with a collar.

[0010] The above-described design employs a multi-section telescopic structure for the traction rod, utilizing a combination of hooks and loops to achieve rapid extension and traction with the telescopic cable assembly. This design, through the adjustable length of the telescopic rod, allows operators to control the rod remotely without stepping on the raised beds, thus avoiding damage to the loose soil structure formed after ridging.

[0011] Furthermore, a stop ratchet is provided on the wire feeding shaft, and a pawl adapted to the stop ratchet is provided on the support platform.

[0012] The above solution disables the ratchet and pawl mechanism, using a one-way locking function to restrict the retraction of the telescopic cable assembly. This prevents the mulch film from loosening and sagging due to wind or gravity after it has been hoisted up.

[0013] Furthermore, the distribution density of the supporting anchor bolts is positively correlated with the length of the tobacco ridge.

[0014] The above scheme supports a design where the anchor density is positively correlated with the length of the tobacco ridge. By dynamically adjusting the anchor spacing, multi-point distributed stress support is formed. In long-ridge environments, high-density anchors can disperse the longitudinal tensile force of wind on the mulch film, reducing the risk of tearing caused by localized stress concentration.

[0015] Furthermore, the connector includes a C-shaped hook disposed on the reinforcing cable, and the back side of the C-shaped hook is provided with a U-shaped overlapping portion, which is adapted to the hook.

[0016] The above-described design utilizes a combination of C-shaped hooks and U-shaped lap joints to resist lateral shear forces through a closed-loop design. The open entrance of the C-shaped hook facilitates quick and easy attachment of reinforcing cables with one hand, while the nested structure of the U-shaped lap joint and the hook creates a self-locking effect under stress, preventing the connection point from coming undone in windy or rainy weather.

[0017] Furthermore, the reinforcing cable is fixed to the mulch film using adhesive tape.

[0018] The above method uses tape for fixing, which facilitates fixing and disassembly, reduces the need for drilling holes in the mulch film, and avoids tearing.

[0019] Furthermore, the distance between the supporting anchor and the tobacco plant is 5-8 cm.

[0020] Furthermore, the pay-off shaft is equipped with a rotating handle.

[0021] The above solution allows for precise adjustment of the cable length by providing a gripping fulcrum, and facilitates tensioning of the telescopic cable assembly.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This system utilizes the slots of the supporting anchor rods to guide the movement of the telescopic cable assembly. Combined with the reinforcing cables at the edge of the mulch film, it forms an adjustable coverage area. During hilling, the telescopic cable assembly is laid out through the traction component and embedded into the slots. The reinforcing cables on the mulch film are fixed to the telescopic cable assembly via connectors, thus lifting the mulch film on both sides of the tobacco plant. The lifted mulch film covers the tobacco, preventing soil clods from entering the tobacco plant during hilling, reducing damage to the plants, and avoiding workers trampling on the ridges. After hilling, the raised mulch film can be re-laid on the surface. Compared to manual mulching, this process reduces labor intensity, standardizes operations, and aligns with the trend of mechanized farming. The overall design directly serves the core objectives of soil moisture retention and warming after ridging, while reserving space for the development of adventitious roots at the stem base during the hilling stage.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1 to 5As shown, this embodiment provides a retractable tobacco ridge cultivation protection device, including a plastic film 11 installed along the length of the tobacco ridges, several supporting anchor rods 12 symmetrically distributed along the length of the tobacco ridges, with a slot 13 at the upper end of the supporting anchor rod 12, and a wire-laying mechanism and a telescopic wire group 14 installed at both ends of the tobacco ridges. The wire-laying mechanism includes a support platform 15 at both ends of the tobacco ridge, a wire-laying shaft 16 installed on the support platform 15, and the telescopic wire group 14 sleeved on the wire-laying shaft 16. Reinforcing cables 17 are installed on the two long sides of the plastic film 11, and the reinforcing cables 17 are fixed to the plastic film 11 with tape. A traction component is installed on the telescopic wire group 14, and the movement trajectory of the telescopic wire group 14 passes through the slot 13. A connector is installed between the telescopic wire group 14 and the reinforcing cable 17. The system utilizes the slots 13 of the supporting anchor rods 12 to guide the movement trajectory of the telescopic cable assembly 14. Combined with the reinforcing cables 17 on the edge of the mulch film 11, it forms an adjustable-size covering surface. During hilling, the telescopic cable assembly 14 is laid out through the traction component and embedded in the slots 13. The reinforcing cables 17 on the mulch film 11 are fixed to the telescopic cable assembly 14 through connectors, thereby lifting the mulch film 11 on both sides of the tobacco plant. The lifted mulch film 11 covers the tobacco plant, preventing soil clods from easily entering the tobacco plant during hilling, reducing damage to the plants, and avoiding workers trampling on the ridges. After hilling, the raised mulch film 11 can be laid back on the ground. Compared with manual mulching, this process reduces the intensity of manual labor, standardizes operations, and aligns with the trend of mechanized farming. The overall design directly serves the core objectives of soil moisture retention and warming after ridging, while reserving space for the development of adventitious roots at the stem base during the hilling stage.

[0034] To facilitate the unwinding and rewinding of the wire, such as Figures 1 to 5As shown, the traction assembly includes a traction rod 18, which is a multi-section telescopic structure. A hook 19 is provided at the end of the traction rod 18, and a collar 20 is provided at the end of the telescopic line assembly 14. The connecting component includes a C-shaped hook 23 on the reinforcing cable 17, with a U-shaped overlapping portion 24 on the back side of the C-shaped hook 23, which is adapted to the hook 19. A stop ratchet 21 is provided on the wire-laying shaft 16, and a pawl 22 adapted to the stop ratchet 21 is provided on the support platform 15. The traction rod 18 adopts a multi-section telescopic structure, and the combination of the hook 19 and the collar 20 enables rapid extension and traction with the telescopic line assembly 14. This design, through the adjustment of the telescopic rod's length, allows the operator to control the ridge remotely without stepping on it, avoiding damage to the loose soil structure formed after ridging. Simultaneously, the combination of the C-shaped hook 23 and the U-shaped overlapping portion 24, through a closed-loop design, resists lateral shear forces. The open entrance of the C-shaped hook 23 facilitates quick one-handed attachment of the reinforcing cable 17, while the nested structure of the U-shaped overlap 24 and the hook 19 creates a self-locking effect under stress, preventing the connection point from coming undone in windy or rainy weather. The stop ratchet 21 and pawl 22 mechanism, through a one-way locking function, restricts the retraction of the telescopic cable assembly 14. This prevents the mulch film 11 from slackening and sagging due to wind or gravity after being hung up. The cable-laying shaft 16 has a rotating handle 25, which provides a gripping fulcrum for fine-tuning the cable length and facilitating the tensioning of the telescopic cable assembly 14.

[0035] Reference Figure 1 The distribution density of the support anchors 12 is positively correlated with the length of the tobacco ridge. For example, a group of support anchors 12 is placed every 3 meters. By dynamically adjusting the anchor spacing, multi-point distributed stress support is formed. In long-ridge environments, the high-density anchors can disperse the longitudinal tensile force of wind on the mulch film 11, reducing the risk of tearing caused by local stress concentration. The distance between the support anchors 12 and the tobacco plants is 5-8 cm, achieving a balance between mechanical protection and root protection through spatial isolation. This distance reduces damage to the main root zone of the tobacco plant when the anchors are inserted, and also reserves growth space for the adventitious roots at the base of the stem to expand outward after soil covering.

[0036] Implementation Principle: This application discloses a retractable protective device for tobacco ridge cultivation. It utilizes the slots 13 of the supporting anchor rod 12 to guide the movement trajectory of the retractable cable assembly 14. Combined with the reinforcing cables 17 at the edge of the mulch film 11, it forms an adjustable coverage surface. During hilling, the retractable cable assembly 14 is laid out via a traction component and embedded in the slots 13. The reinforcing cables 17 on the mulch film 11 are fixed to the retractable cable assembly 14 via connectors, thereby lifting the mulch film 11 on both sides of the tobacco plant. The lifted mulch film 11 covers the tobacco, preventing soil clods from entering the tobacco plant during hilling, reducing damage to the plants, and avoiding workers trampling on the ridges. After hilling, the raised mulch film 11 can be re-laid on the ground. Compared to manual mulching, this process reduces manual labor intensity, standardizes operations, and aligns with the trend of mechanized farming. The overall design directly serves the core objectives of soil moisture retention and warming after ridging, while also reserving space for the development of adventitious roots at the stem base during the hilling stage.

[0037] It should be noted that the connection relationships of components not specifically mentioned in this application are all assumed to be based on existing technology. Since they do not involve the inventive point and are commonly used in existing technology, the structural connection relationships are not described in detail.
