Description

Technical Field

[0001] This invention relates to the field of forest tree cultivation auxiliary tools, specifically to a support method and device for cultivating tree seedlings. Background Technology

[0002] In the field of garden seedling cultivation, trees, especially some large-sized tree seedlings such as arbor trees, have shallow root systems. During the planting and cultivation stage, their ability to resist wind, rain and external disturbances is extremely poor. They are easily affected by adverse external environmental factors such as wind, rain and airflow, resulting in problems such as falling over, leaning, and loosening of the root system. This seriously reduces the survival rate of seedlings and the regularity of seedling growth. Therefore, seedling support and fixation is an indispensable key process in the large-scale cultivation of seedlings.

[0003] Currently, in horticultural seedling cultivation, traditional seedling support techniques mostly employ a single-seedling independent support model. Common methods include directly binding bamboo poles or wooden sticks for support, single-point clamping for fixation, and even directly fixing a triangular wooden frame made of three wooden blocks to the trunk with nails to help the roots stand stably on the ground and maintain their growth posture. These traditional support techniques have serious limitations in adaptability and practicality, making it difficult to meet the needs of modern, large-scale seedling cultivation operations.

[0004] Specifically, the most typical drawback is that traditional support methods involve individually setting up and fixing support structures for each sapling, resulting in a cumbersome process, high labor costs, and an inability to provide unified support for batches of saplings. In large-scale seedling cultivation scenarios, the efficiency of support operations is extremely low, requiring the installation of numerous triangular frames such as wooden blocks, or crisscrossing protective beams or pipes, leading to high labor costs. Furthermore, traditional rigid support components are highly rigid and have a single contact method, making them prone to scratching and squeezing damage to the bark and tender branches of saplings during binding or rigid clamping. Additionally, traditional wooden supports, erected around each tree, are susceptible to loss of support due to the settlement of the backfill soil after planting, leading to poor clamping fit, one-sided stress, and resulting in skewed sapling growth and poor support stability.

[0005] Meanwhile, the existing large-scale forestry bases use crisscrossing mesh protective supports, which not only require a series of timber and bamboo, resulting in huge material consumption, but also have fixed support structures with poor flexibility. They are only suitable for regular straight seedling planting paths, have limited functionality and limited adaptability to different scenarios, and cannot be adapted to seedling support operations on complex curved paths such as arcs and broken lines, especially not to natural cultivation sites in natural forest areas. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a support method and device for the cultivation of tree seedlings, so as to solve the problem that it is difficult to quickly support a large number of seedlings during the current cultivation of tree seedlings, and the support stability is not strong, making it difficult for the whole group of seedlings to form a joint force system to resist wind and rain, which is not suitable for the diversified, large-scale and complex seedling cultivation scenarios of modern gardens.

[0007] This invention is achieved through the following technical solution: A method for supporting tree seedlings during cultivation includes the following steps: S1. Select several saplings along the preset path in the sapling planting area to be supported, and form a group of saplings to be supported. S2. Install an anchor rod at each end of the path where the seedling group is located, and fix the anchor rod vertically to the ground. S3. Fix one end of each of the two cables to the first anchor rod. After the other end of each cable is fitted with a support fork, the two support forks slide along their respective cables to the two opposite sides of the sapling closest to the first anchor rod. Connect the support forks to form a support assembly. The support assembly is equipped with several sliding columns that can move closer to each other. When all the sliding columns move closer to each other and squeeze the sapling in the center, fix the sliding columns so that the support assembly hugs the sapling tightly. S4. Repeat step S3 to install the corresponding support components on the remaining saplings of the sapling group one by one according to the path direction. S5. Finally, secure the other ends of both cables to the second anchor rod, and ensure that the cables are ultimately taut.

[0008] Furthermore, the two cables are arranged parallel to each other on the same horizontal plane, and the seedlings of the seedling group are in a straight line.

[0009] Furthermore, when the path of the seedling group is curved, the perforation on the support fork at each bend through which the cable passes is a curved hole with a smooth inner wall, consistent with the bending direction at the bend.

[0010] The present invention also provides a support device for cultivating tree seedlings, including the aforementioned support fork. The support fork includes a connecting block for the cable to pass through and a semi-circular ring for the sliding column to be slidably installed. The connecting block is integrally formed and fixed to the center of the outer side of the semi-circular ring. The top surface of the semi-circular ring has an arc-shaped mounting groove coaxial with it and extending through both ends. The sliding column is slidably installed radially at the lower part of the semi-circular ring. The upper surface of the sliding column is provided with a planar thread that can be located in the mounting groove. The two semi-circular rings are joined together by a positioning pin to form a ring. After joining, a transmission ring is coaxially rotatably installed in the annular groove formed by splicing the two mounting grooves. The transmission ring is formed by splicing two semi-rings together by positioning pins, and each semi-ring is located in one of the mounting grooves. The bottom end surface of the semi-ring is provided with a planar thread that meshes with the sliding column, so that when the transmission ring is rotated, all the sliding columns move closer together and hug the central seedling tightly.

[0011] Furthermore, the mounting block is embedded with a sleeve that runs through its left and right sides. The inner wall of the sleeve is smooth to allow the cable to pass through freely. The sleeve includes a straight tube and a curved tube. The straight tube is fixed to the support fork of the sapling in the straight direction of the sapling group, while the curved tube is used for the support fork of the sapling at the bend of the sapling group in the path.

[0012] Furthermore, a fixed pulley is installed inside the mounting block, and a limit stop is fixed on the axle of the fixed pulley. The limit stop is used to maintain the sliding and winding engagement relationship between the cable and the fixed pulley to prevent the cable from detaching from the fixed pulley; the sliding column is an elastic telescopic structure so that it can elastically contact the seedling to transmit force.

[0013] Furthermore, the mounting block has a cable sleeve on each side of the mounting cavity for mounting the fixed pulley, and the cable sleeve is used for sliding cooperation to pass through and wrap around the fixed pulley.

[0014] Furthermore, the cable is wrapped with a smooth, wear-resistant rubber sleeve, and a sealing ring is coaxially positioned inside the port of the cable sleeve facing the outer end of the positioning block. The wear-resistant rubber sleeve passes through the sealing ring in a dynamic sealing fit.

[0015] Furthermore, it also includes a two-part spliced ​​protective cover. The top surface of the support fork has an annular groove in which a sealing ring is embedded. The sealing ring is formed by a sealing strip embedded along the annular groove. After the protective cover is spliced, it is threaded onto the two spliced ​​semicircular rings and the sealing strip is pressed tightly. The outer side of the protective cover has several strip-shaped extension chambers integrally formed. Each extension chamber is for a corresponding sliding column to slide into. After the protective cover and the semicircular ring are threadedly fitted, each extension chamber is aligned with the sliding hole on the corresponding semicircular ring for the sliding installation of the sliding column.

[0016] Furthermore, the present invention also includes a number of retractable protective sheds, the same number as the sliding columns. The top of the protective shed is raised upwards to allow for waterproofing and drainage. Its lower end is fixed to the edge of the top of the semi-circular ring, and its higher end is connected to a vertically set non-rigid liner. The ends of the sliding columns that are close to each other are fixed with arc-shaped sheet-like pressure tiles. The pressure tiles and the liner tiles can fit together so that when the seedling is held tightly, the liner tiles are sandwiched between the pressure tiles and the seedling, and the protective shed can completely cover and shield the part of the sliding column exposed inside the support fork.

[0017] The beneficial effects of this invention are as follows: This invention relates to a method and apparatus for supporting tree seedlings. Through a combination of several support components connected by a pair of cables, a flexible and adjustable encircling support structure with a fixed tree diameter, and a comprehensive protective structure, it achieves several significant technical effects. The specific principles and structural designs of this invention are explained below: 1. Achieving large-scale batch support operations and significantly improving seedling support efficiency: This invention completely departs from the traditional single-seedling independent support operation mode. It does not rely on the soil at the seedling planting site as a support carrier, but instead constructs a stable support base using two anchor rods. Only two anchor rods need to be fixed independently, thus allowing for backfill soil relatively far from the seedling planting site. This ensures stable soil quality, preventing subsidence and loosening, and serves as a load-bearing foundation. By connecting multiple sets of support components with flexible cables, neatly arranged groups of seedlings can be centrally and synchronously supported and fixed, achieving integrated support operations for batch seedlings. This greatly simplifies the seedling support process, reduces manual operation procedures and operation time, and is suitable for the large-scale seedling needs of large-scale seedling planting bases. The support operation efficiency is significantly improved compared to traditional processes, effectively reducing seedling labor costs. Simultaneously, the entire group of seedlings forms a unified force-bearing system through cable linkage, which can collaboratively resist external forces such as wind and rain. Compared to single-seedling independent support, the overall resistance to lodging and tilting is significantly enhanced, effectively ensuring the seedlings grow in a regular posture, and it also has high reusability.

[0018] 2. It can better fit the trunks of seedlings with different diameters, providing uniform and stable support with minimal damage to the seedlings: This invention employs a fixing structure with multiple sets of synchronously sliding columns that radially contact and press together. Through the threaded engagement of the transmission ring, multiple sliding columns can synchronously move towards the center, precisely adapting to the trunks of seedlings with different diameters. Simultaneously, the ends of the sliding columns can use flexible materials or elastic telescopic structures to adaptively fit non-circular tree trunks, achieving uniform contact and force transmission throughout the circumference. This completely solves the problems of single-point force, uneven clamping, and damage to bark and tender branches caused by traditional rigid supports. Furthermore, the accompanying lining and pressure pad buffer isolation structure further weakens the clamping and squeezing force, providing all-round protection for the seedling trunk and ensuring healthy seedling growth while providing stable support.

[0019] 3. Adaptable to various seedling cultivation paths, including straight and curved sections, offering wide scenario adaptability and strong practicality: This invention utilizes the flexibility of the cables, allowing for flexible relocation and installation, to adapt to different seedling cultivation scenarios. For example, if the cables employ a differentiated perforated installation structure, straight seedling cultivation paths utilize straight-tube support forks to ensure parallel and equidistant cable placement, resulting in even and symmetrical stress on the seedlings and avoiding unilateral skewing. Curved and zigzag-shaped seedling cultivation paths employ curved-tube support forks adapted to the curvature, combined with a smoothly polished perforated structure, preventing rigid bending, wear, and jamming of the cables, ensuring proper assembly of seedling support components at bends, and effectively protecting the cable structure while extending its service life. In practice, using fixed pulleys is preferable, as it saves effort and offers greater flexibility in cable and support component placement. In addition, thanks to the adjustable characteristics of the flexible cable, the support components can slide flexibly on the cable and be finely adjusted in height, avoiding uneven parts such as saplings, branches, and knots, and selecting a position on a rounded trunk for fixation, further improving the flexibility and adaptability of the support operation.

[0020] 4. Scientifically and rationally designed structure, convenient assembly and disassembly, reliable locking, and high operational stability: This invention adopts a splicing structure of a two-half support fork and a split transmission ring, making assembly, disassembly, and maintenance convenient without the need for complex installation tools, and suitable for rapid outdoor operations. Through planar thread meshing transmission and bolt locking structure, the clamping force of the sliding column can be precisely controlled, and the structure is stable and not easily loosened after locking, ensuring strong support reliability. At the same time, the addition of a pulley and cable sleeve guide and limit structure, combined with a limit baffle anti-detachment design, can significantly reduce the sliding friction resistance of the cable, eliminate problems such as cable deviation, derailment, and detachment, ensure the cable is taut throughout the process, prevent the support structure from loosening and failing, and improve overall operational stability.

[0021] 5. Comprehensive sealing and protection, high outdoor durability, and low failure rate: This invention features a multi-layered protective structure, significantly improving the reliability of the device for long-term outdoor use. The cable is covered with a wear-resistant rubber sleeve, effectively preventing wear and corrosion; the cable sleeve port is equipped with an elastic sealing ring, forming a dynamic seal structure to prevent rainwater, sand, and mud from entering the device. A two-part sealing protective cover completely shields the internal threads, sliding columns, transmission rings, and other precision structures, working in conjunction with the extension chamber structure to achieve sliding column limiting and comprehensive protection; simultaneously, a flexible, retractable protective shed forms a drainage and waterproof structure, effectively preventing rainwater erosion and debris jamming of transmission threads and sliding parts, eliminating problems such as component corrosion, jamming, and failure, significantly extending the overall service life of the device and reducing the maintenance cost of seedling equipment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the 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 invention without inventive effort are within the scope of protection of the invention.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Please see Figure 1 This invention provides a technical solution: a support method for cultivating tree seedlings, particularly suitable for supporting relatively large tree seedlings such as arbor trees. The specific implementation process is as follows: First, in the planting area for cultivating garden tree seedlings, according to the pre-selected planting extension path of several seedlings, these seedlings are grouped into a group of seedlings to be supported, realizing unified support operation for batch seedlings to improve cultivation support efficiency. Then, at the beginning and end of the planned path of the seedling group, an anchor rod is installed at each end, and the two anchor rods are driven vertically into the ground and firmly fixed to ensure that the anchor rods do not shake or tilt, providing a stable support base for the subsequent tensioning and fixing of the cables. Next, select two suitable flexible cables 7, and fix one end of each cable 7 to the first anchor at the beginning of the path. Each cable 7 is then fitted with a pair of support forks 1, so that the cables 7 pass through the support forks 1, or the two support forks 1 are fitted onto the two cables 7, allowing them to slide freely along their respective cables 7. Then, slide the two support forks 1 to opposite sides of the single sapling closest to the first anchor within the sapling group, for example, one support fork 1 on each side (front and back). Figure 2As shown, the two support forks 1 are precisely connected and spliced ​​to form a complete support component for a sapling. At the same time, in order to adapt to the different diameters of saplings along the path, the support component is equipped with multiple sets of sliding columns 4 that can slide and approach each other. By adjusting the sliding state of the sliding columns 4, all the sliding columns 4 are moved towards the center of the support component synchronously until they are pressed against the sapling trunk located in the center of the component. Then, all the sliding columns 4 are locked and fixed, and the approaching sliding columns 4 are used to achieve a tight and positioned support for a single sapling. Of course, based on existing technology, rigid components are not directly used to support saplings. In this embodiment, the end of the sliding column 4 can also be embedded with a corresponding flexible or elastic material such as rubber to ensure friendly contact with the sapling and minimize damage to the bark. Alternatively, the sliding column 4 can directly adopt an elastic telescopic structure. For example, the sliding column 4 can be set as two interlocking sections, with one section inserted into the other and connected to a spring inside the other section, thereby achieving elastic support. This not only protects the sapling but also effectively prevents the tree from being too round, ensuring that all sliding columns 4 can contact the sapling to transmit force and provide circumferential fastening and support. In practice, when the sapling at the height of the cable 7 has branches or burls that are unfavorable for installing support components, the cable 7 can be moved up or down a certain distance to select a relatively rounded part for installation. Since the cable 7 is used to flexibly connect all support components, the support components can be positioned not only out of line but also out of horizontal plane, providing great flexibility and convenience for sapling cultivation and maintenance, making it highly practical. Following the steps described above, continue with the same procedure: extending along the planned path of the sapling group, sequentially equip each remaining sapling in the group with its corresponding support components, similar to stringing a bracelet, completing the support installation for each sapling in the group. Finally, after all saplings have their support components installed, fix the free ends of the two cables 7 to the second anchor at the end of the path. Adjust the tension of the cables 7 throughout the process to ensure they remain continuously taut, preventing slack or sagging. This completes the centralized support and fixation of the entire group of saplings. The support operation is not only highly efficient but also highly reliable. The saplings work together to withstand wind and rain, effectively preventing them from falling over or tilting, and ensuring their uniform growth posture.

[0029] In this embodiment, during the seedling support operation, after the vertical fixing of the anchor rods at both ends is completed, when laying the two cables 7, the two cables 7 are adjusted to the same horizontal height, maintaining a parallel and evenly spaced arrangement without crossing or misalignment. This is mainly for large-scale seedling planting bases where the seedlings are generally in a uniform growth state and the nursery is well-organized. In fact, generally speaking, most trees have unbranched trunks with good roundness near the bottom, which can be used to fix and install the support components. Alternatively, all seedlings in a specially selected and collected seedling group can be arranged neatly along a pre-set straight planting path, with the center point of all seedlings on the same straight line. During operation, the support components corresponding to each sapling are symmetrically assembled between two parallel cables 7. Relying on the parallel and equidistant cable 7 structure and the linear arrangement of saplings, the supporting force on each sapling is uniform and symmetrical, effectively avoiding the problem of unilateral force and tilting caused by cable 7 misalignment and uneven sapling arrangement. This further improves the support stability and regularity of saplings planted in a straight line, making it suitable for large-scale linear seedling cultivation. However, it is not suitable for random planting in mountainous areas, especially for seedlings that are randomly planted and prepared for cultivation in places such as parks.

[0030] Therefore, to adapt to seedling support in complex situations and address seedling support scenarios with curved planting paths, the specific implementation method is as follows: When the planting path of the seedling group is a non-linear curved path such as an arc or a broken line, or when such a curved path must be chosen to adapt to the planting site, a special support fork 1 with a corresponding structure can be provided for each seedling at each bend in the path. Specifically, the support fork 1 used at the bend position has a correspondingly shaped perforation for the cable 7 to pass through. The inner wall of the perforation is smoothed to eliminate burrs and protrusions, reducing the sliding friction of the cable 7. At the same time, the perforation is set as a curved hole structure adapted to the bending direction of the path, and the curvature of the hole roughly corresponds to the curvature of the seedling path, mainly to facilitate the final tightening and fixing of the cable 7. During the support operation, the cable 7 passes through the bend and is taut. The cable 7 can slide smoothly against the inner wall of the bend and be laid out in accordance with the bend direction, avoiding forced bending of the cable 7 as much as possible. This ensures the normal assembly and tight support effect of the seedling support components at the bend position, and also avoids wear, jamming, deformation and breakage of the cable 7 due to hard bending. It is suitable for batch support operations of curved seedling cultivation paths, ensuring the support stability of curved seedlings and the service life of the cable 7.

[0031] Based on the above-described support method, this embodiment discloses in detail a support device for cultivating tree seedlings, for use with the aforementioned support method. It also serves to fully illustrate the feasibility of the method, such as... Figures 2-3As shown, it mainly includes the aforementioned support forks 1 used in pairs. Each support fork 1 is integrally formed from a connecting block and a semi-circular ring, avoiding secondary installation and ensuring strong structural integrity, making it less prone to loosening and damage. The connecting block is fixedly positioned at the center of the outer side of the semi-circular ring, and a through-hole structure is formed inside the connecting block as the aforementioned perforation, allowing the cable 7 to pass through and achieve a sliding fit between the support fork 1 and the cable 7. See also... Figures 4-5 The top end face of the semicircular ring has a coaxial, through-hole arc-shaped mounting groove 101. Inside the lower part of the semicircular ring, multiple freely sliding sliding pillars 4 are mounted radially. The upper surface of each sliding pillar 4 is machined with a flat thread structure, which protrudes inside the arc-shaped mounting groove 101 to engage with the flat thread on the transmission ring 3 (mentioned below). In actual assembly, two symmetrical semicircular rings are selected and precisely joined together using locating pins 9 inserted into pin holes 105 to form a complete circular support frame. The arc-shaped mounting grooves 101 of the two semicircular rings are simultaneously joined to form a closed annular groove. The transmission ring 3 is coaxially mounted inside the annular groove. Similarly designed, the transmission ring 3 is formed by two symmetrical semicircular rings joined together by pins. The two semicircular rings are respectively installed into the mounting grooves 101 of the two semicircular rings, achieving a split-type assembly. At the same time, a planar thread structure matching the planar thread on the upper surface of the slide column 4 is machined on the bottom end face of each half ring, so that the half ring and the slide column 4 form a threaded meshing transmission fit.

[0032] In the specific manufacturing process, for the structural installation design of the transmission ring 3, as one implementation method, a half-ring can be placed in one of the mounting slots 101, rotated to the corresponding mounting slot 101, and then another half-ring can be placed in the corresponding position of the other mounting slot 101. Here, the pin between the two half-rings is a flexible mounting pin, that is, when pressed, the pin will be inserted into the corresponding pin mounting hole. Because the splicing of the support fork 1 can be directly connected, but the splicing of the transmission ring 3 cannot be directly connected, they can only be placed into the mounting slots 101 one by one and finally connected. Therefore, the above-mentioned flexible telescopic pin needs to be designed for connection.

[0033] As another implementation: when the machining accuracy of the mounting groove 101 is sufficient, the two half-rings of the transmission ring 3 can be directly placed into the mounting groove 101 to form the transmission ring 3. However, this structure requires relatively high machining accuracy; if the accuracy is insufficient, the planar threads may not be able to be combined into a complete thread. To prevent the transmission ring 3 from detaching from the mounting groove 101, a detachment-preventing plate 102 can be radially extended from the inner sidewall of the groove opening of the mounting groove 101, partially covering a certain part of the inner end face of the transmission ring 3. A detachment-preventing plate 102 can be made to facilitate the individual rotation and placement into the mounting groove 101. Figure 3If multiple anti-detachment plates 102 are set as shown, the transmission ring 3 needs to be machined with a corresponding number of notches so that it can be inserted into the mounting groove 101 along the anti-detachment plate 102, and it will not easily fall out of the mounting groove 101 when rotating.

[0034] For the structural design of the transmission ring 3, as a third implementation method, it is also possible to use two upward-protruding rectangular plates (not shown in the figure) to connect at both ends. The rectangular plates are perpendicular to the end face of each half ring. Thus, after the two half rings are put into the corresponding mounting slots 101, the transmission ring 3 can be rotated and installed on the end face of the support fork 1 by directly fixing the two sets of opposing rectangular plates through bolts.

[0035] In addition, to facilitate the rotation of the transmission ring 3, a crank handle 15 can be fixed to the end face of the transmission ring 3 for manual rotation. After rotation, the transmission ring 3 is pressed by vertically installing locking bolts on the anti-detachment plate 102, thereby locking the position of the sliding column 4 and maintaining the fixed state of the support component and the seedling. Since the bolt locking structure is commonly used, it is not shown separately in detail in the accompanying drawings of this specification. Those skilled in the art can easily conceive of and implement it. In actual use, manually rotating the assembled transmission ring 3, relying on the thread meshing transmission principle, can drive all the sliding columns 4 to move synchronously towards the center along the radial direction of the semi-circular ring. Finally, through the synchronous squeezing action of multiple sets of sliding columns 4, the seedling trunk located in the center of the device is uniformly and circumferentially tightened and fixed, achieving stable support for the seedling. The overall device is easy to assemble and disassemble, and the tightening force is uniform and controllable.

[0036] In this embodiment, as Figure 2 As shown, a fixed sleeve 8 can be embedded inside the connecting block of the support fork 1. The sleeve 8 completely penetrates the left and right sides of the connecting block, forming a through channel for the cable 7. The inner wall of the sleeve 8 is smoothly processed to minimize the frictional resistance during the passage and sliding of the cable 7, ensuring that the cable 7 can pass freely and smoothly within the sleeve 8 without jamming or obstruction. As mentioned in the aforementioned support method, the sleeve 8 is divided into two structural types according to the shape of the seedling planting path: straight pipe and curved pipe, which are classified to adapt to different planting scenarios. For each seedling support fork 1 on the straight planting path of the seedling group, a fixed straight pipe structure is uniformly embedded. For the support fork 1 of the seedlings at the bend position of the curved planting path of the seedling group, a curved pipe structure is uniformly embedded. The bending direction of the curved pipe can be adapted to the bend direction of the path, which effectively solves the problem of wear and displacement of the cable 7 at the bend of the curve, allowing the device to adapt to the support operation of various seedling cultivation paths, including straight and curved ones, with wider adaptability.

[0037] In this embodiment, in addition to using the above-mentioned perforation structure, or the structure of sleeve 8, it is also possible to use... Figure 6As shown, a fixed pulley (not shown) is fixedly installed in the internal cavity near the end of the connecting block. The cable 7 is wound around the fixed pulley, which guides and supports the cable 7 during its sliding process, further reducing frictional loss during tensioning and sliding. It also allows for flexible adaptation to bending paths and the bending direction of the cable 7. Simultaneously, limiting plates are fixedly installed at both ends of the fixed pulley axle, covering the openings at both ends of the pulley groove. Such commonly used fixed pulleys are commercially available and are not specifically shown in this embodiment. During the sliding and tensioning operation of the cable 7, the limiting plates on both sides maintain the wrapped engagement between the cable 7 and the pulley groove, effectively preventing the cable 7 from detaching from the pulley groove or derailing when under tension or sliding deviation. This eliminates support failure caused by the cable 7 falling off, improving the stability and reliability of the device.

[0038] In this embodiment, as Figure 6 As shown, a cable guide sleeve 10 is fixedly installed on each of the left and right side walls of the mounting cavity for installing the fixed pulley in the connecting block. The two cable guide sleeves 10 can be arranged symmetrically, and the through holes of the cable guide sleeves 10 correspond precisely to the grooves of the fixed pulley. When assembling the cable 7, it passes through one side cable guide sleeve 10 in sequence, wraps around the groove of the fixed pulley, and then exits from the other side cable guide sleeve 10. The inner wall of the cable guide sleeve 10 and the outer wall of the cable 7 form a sliding fit, which can precisely guide and limit the entry and exit path of the cable 7. In specific manufacturing, a sealing plate 19 can be detachably installed on the cavity for installing the fixed pulley, so that it can be sealed after the fixed pulley is installed, improving the reliability of outdoor rain and dust protection. In this design, the regular constraints of the two side guide sleeves 10 ensure that the cable 7 always maintains the preset travel angle and position, preventing the cable 7 from shifting or shaking inside the installation cavity. In addition, the fixed pulley and limit baffle structure further ensure that the cable 7 slides smoothly and does not fall off, thus improving the overall guiding and protective performance of the device.

[0039] In this embodiment, a wear-resistant rubber sleeve is wrapped around the entire exterior of the cable 7. This sleeve is made of a highly wear-resistant and tough flexible material, integrally molded to completely cover the outer surface of the cable 7, preventing direct friction, wear, corrosion, and aging, thus extending the cable 7's service life. Simultaneously, a sealing ring 11 is coaxially fixed inside the end of the cable sleeve 10 facing the outside of the connecting block. The sealing ring 11 is made of an elastic sealing material. During the assembly of the support fork 1, the rope wrapped in the wear-resistant rubber sleeve passes through the sealing ring 11, forming a dynamic sealing fit with the sealing ring 11, providing waterproofing and dustproofing. This lays the structural foundation for the stable and reliable operation of the fixed pulley. During the continuous sliding and tensioning operation of the cable 7, the sealing ring 11 always adheres to the outer wall of the wear-resistant rubber sleeve, effectively preventing external impurities such as mud, sand, and rainwater from entering the cable sleeve 10 and the connecting block. This avoids the accumulation of impurities causing jamming and corrosion of components, while not affecting the normal sliding of the cable 7, achieving a dual effect of sliding protection and sealing against dust.

[0040] like Figure 7 As shown, to improve reliability for long-term outdoor use, this embodiment also includes a specially designed two-part splicing protective cover 12. The two cover parts are symmetrical and can be quickly joined together. A sealing gasket 20 is sandwiched between the two cover parts for sealing. An annular groove is formed on the top end face of the support fork 1, as shown. Figure 2 As shown, the entire flexible sealing strip is embedded inside the annular groove to form an integrated sealing ring 2. After the protective cover 12 is assembled, it forms a threaded locking structure with the pipe threads 103 on the outside of the two semi-circular rings through the inner thread structure. It covers the outside of the two semi-circular rings and tightly presses the sealing strip in the groove, achieving a sealed fit between the cover and the semi-circular rings, preventing impurities and rainwater from entering the internal transmission structure. In specific manufacturing, as shown... Figure 7 , Figure 11 As shown, the protective cover 12 has connecting plates (not shown in the figure) at both ends. Alignment pins 16 for positioning and studs 17 and nuts 18 for fixing are inserted into the connecting plates. Furthermore, to fully expand the adaptability of the support assembly to seedling sizes while minimizing the external dimensions of the support assembly, multiple sets of strip-shaped extension chambers 1201 can be integrally formed on the outer side of the protective cover 12. The number of extension chambers 1201 corresponds one-to-one with the number of sliding columns 4 inside the device, and the opening position of each extension chamber 1201 is precisely aligned with the sliding hole 104 on the semi-circular ring for sliding installation of the sliding column 4. When the sliding column 4 slides closer and resets with the transmission structure, the outer end of the sliding column 4 can smoothly slide into the corresponding extension chamber 1201. The extension chamber 1201 limits and guides the sliding stroke of the sliding column 4. Simultaneously, the protective cover 12 completely shields and protects the internal sliding column 4, threads, transmission ring 3, and other precision structures, preventing external debris and rainwater from eroding the internal transmission structure and ensuring long-term stable operation of the device.

[0041] In this embodiment, as Figure 7 As shown, to enhance protection and reliability, this embodiment specifically includes multiple sets of retractable protective canopies 13, the same number as the sliding columns 4. The protective canopies 13 are made of flexible, retractable material, allowing for retraction and movement, or elastic retraction and movement, such as... Figures 8-9 The overall structure features a centrally raised top, forming a drainage structure that is high in the middle and low on both sides, similar to a greenhouse. This provides excellent waterproofing and drainage, preventing rainwater from eroding the flat threads on the sliding columns 4. The protective canopy 13 is installed at an angle, with its lower end fixed to the top edge of the semi-circular ring, and its higher end vertically fitted with a liner 14. The liner 14 is a protective material used for contact with the sapling. Simultaneously, at the end of all sliding columns 4 facing the center of the device and used to hold the sapling, an arc-shaped sheet-like pressure tile 5 is fixedly installed, such as... Figure 10 The curved surface of the pressure tile 5 presses against the outer wall of the lining tile 14, thus clamping the lining tile 14 between the sapling and the pressure tile 5 when the support assembly is installed, thereby installing the protective shed 13. When multiple sets of sliding columns 4 simultaneously approach and hug the central sapling, the lining tile 14 is inserted and fitted between the outer wall of the sapling trunk and the pressure tile 5. This not only allows for the installation of the protective shed 13 but also provides isolation and buffering through the lining tile 14, preventing direct compression and abrasion of the sapling's tender branches if a rigid pressure tile 5 were used. When installed, the protective shed 13 completely covers all parts of the sliding column 4 exposed outside the support fork 1, preventing debris from jamming the sliding column 4 and affecting the transmission and sliding effect, thus achieving the dual function of protecting both the sapling and the device.
