Description

Technical Field

[0001] This utility model relates to the field of forestry seedling protection, specifically to a combined forestry seedling protection frame with composite structure support rods. Background Technology

[0002] The forestry industry is an important support for my country's green development, and afforestation is the basic guarantee for the national forestry industry. Because newly planted forestry seedlings are fragile and have poor environmental adaptability, in order to effectively improve the survival rate of forestry seedlings and ensure the normal development and healthy growth of planted trees, it is usually necessary to use special support and protection devices to support and protect newly planted forestry seedlings, and to help enhance the wind resistance and lodging resistance of forestry seedlings, so as to prevent forestry seedlings from tilting and falling, which would damage the root system or even cause the seedlings to die. Existing technologies have disclosed various technical solutions for forestry seedling support and protection devices. Among these, combined forestry seedling support and protection devices typically employ a single straight rod structure to balance and support the seedlings. For example, the utility model patent with authorization announcement number CN222424905U specifically discloses "a unit component combined forestry seedling support and protection frame." This support and protection frame is constructed using standardized unit components as basic units, achieving "optimized structure, improved function, increased efficiency and protection effect for forestry seedling support operations, expanded application scope, and protection of forestry seedlings." While the utility model aims to promote "healthy growth," its use of a single straight rod structure secured by pins to support the seedlings presents challenges. Simultaneously, the seedlings sway in the wind, causing the support rods to continuously oscillate under the influence of irregularly changing horizontal forces. This oscillation easily loosens the pins securing the support rods, reducing the firmness and stability of the pins' fixation. Consequently, the reliability of the support frame in supporting the seedlings decreases, and in severe cases, it can even lead to imbalance and tilting, rendering the support frame ineffective. Therefore, given the significant safety hazards inherent in existing forestry seedling support and protection devices, it is necessary to research and improve the support structure of these devices to address the current technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a combined forestry seedling protection frame with composite structure support rods, which enhances the stability of fixed support for forestry seedlings and improves the reliability of safety protection for forestry seedlings.

[0004] A composite forestry seedling protection frame with a composite support rod is composed of unit components, each unit including: a positioning block, a connecting block, a first support rod, and a second support rod. The positioning block and the connecting block are arc-shaped bodies with the same curvature. Two connecting blocks are respectively connected to the two ends of the positioning block, forming a continuous arc shape. The inner arc surface of the positioning block serves as a seedling support surface, protruding from the inner arc surface of the connecting block, allowing for support and cooperation with the forestry seedlings. The first and second support rods are both rigid straight rods. One end of the first support rod is hinged to the outer arc surface of the positioning block, and the other end is hinged to a first ground pad. One end of the second support rod is hinged to the first support rod on the corresponding connection side between the first support rod and the positioning block, and the other end is hinged to a second ground pad. Piercing holes are respectively provided on the first and second ground pads. Connecting structural members corresponding to the piercing hole structure can be used to connect the first support rod and the second support rod respectively. The support rod is locked and fixed to the ground. The first and second support rods, which are connected to each other, form a composite support rod structure. In use, the second support rod can be flipped and unfolded relative to the first support rod at an angle α, and locked and fixed to the ground together with the first support rod. The second support rod is used to assist in limiting the stability of the first support rod in its supported state, constraining and limiting the swaying amplitude of the first support rod caused by the reaction of the forestry seedlings, ensuring the firmness and stability of the locking and fixing of the connecting structure to the first support rod, and improving the reliability of supporting and protecting the forestry seedlings. At least three of the unit components are used in combination. The ends of the connecting blocks on each unit component are connected sequentially and detachably to form a closed loop in which the positioning blocks are evenly distributed along the circumference. At the same time, when the second support rod is unfolded, the composite support rod unfolds outward from the closed loop and is fixed to the ground by the first and second ground mats respectively, providing balanced support to the closed loop and providing reliable support and protection for the forestry seedlings.

[0005] The aforementioned combined forestry seedling protective frame with composite support rods preferably features a pull-out sleeve on the first support rod that allows for length adjustment, and a threaded sleeve on the second support rod that allows for length adjustment by rotation. Adjusting the length of the first support rod using the pull-out sleeve allows for setting the height of the closed loop according to the forestry seedling cultivation process requirements, and also allows for adjusting the horizontal state of the closed loop based on ground slope and unevenness. Adjusting the length of the second support rod using the threaded sleeve allows its length to adapt to the setting state of the first support rod. While ensuring the setting height and horizontal state of the closed loop, this design effectively serves as an auxiliary limiting mechanism, further enhancing the stability of the first support rod.

[0006] The composite forestry seedling protection frame with a composite structure support rod further includes: a third support rod, which is a rigid straight rod. A limiting guide groove is provided on the first support rod along its length. One end of the third support rod is hinged to the second support rod, and the other end is slidably connected to the first support rod by the limiting guide groove. Locking the connection between the third support rod and the first support rod allows the first, second, and third support rods to form a stable triangular frame support structure. This solidifies the function of the second support rod in assisting the limiting of the first support rod, further enhancing the stability of the first support rod's support state and fully ensuring the reliability of the support and protection for the forestry seedlings.

[0007] The aforementioned combined forestry seedling protective frame with composite structure support rods preferably has the third support rod and the second support rod coaxially hinged to the second ground mat at the connection end, which improves the coordination of the triangular frame support structure, optimizes the connection structure of the composite structure support rods, and enables the composite structure support rods to be centrally stored in a unidirectional bundled state, effectively reducing the space occupied for storage and transportation and improving the efficiency of production application.

[0008] The aforementioned combined forestry seedling protection frame with composite structure support rods preferably uses U-shaped bolts to connect the unit components. Insertion holes are respectively provided at the connecting ends of the connecting blocks, and these insertion holes correspond to the two insertion rods on the U-shaped bolts. By inverting the U-shaped bolts and inserting the two insertion rods into the corresponding insertion holes on the two connecting blocks, the two unit components can be assembled and connected. Conversely, by pulling out the U-shaped bolts, the two unit components can be separated. The assembly and disassembly procedures are simple and easy to operate.

[0009] The beneficial effects of this utility model are that it provides a combined forestry seedling protective frame with a composite structure support rod, improving the support structure of the existing unit component combined forestry seedling protective frame. By combining the first and second support rods to form a composite structure support rod, the stability of the support and protection for forestry seedlings is enhanced. Furthermore, by combining the third support rod with the first and second support rods to form a triangular frame support structure, the function of the second support rod in assisting and limiting the first support rod is solidified, further enhancing the stability of the support and protection for forestry seedlings and fully ensuring the reliability of the support and protection. Moreover, the first, second, and third support rods can be centrally stored in a unidirectional bundle, effectively reducing storage and transportation space occupation, improving production application efficiency, ensuring the healthy growth of forestry seedlings in production applications, reducing production cost input, improving the survival rate of afforestation, and well meeting the needs of industrialized afforestation production.

Detailed Implementation

[0018] Furthermore, the technical solution for which protection is sought in this utility model will be described in detail below with reference to specific embodiments and accompanying drawings.

[0019] A combined forestry seedling protective frame with composite structure support rods, such as Figures 1 to 3 As shown, it is composed of four standardized unit components, such as... Figures 4 to 7As shown, the device consists of a positioning block 1, a connecting block 2, a first support rod 3, a second support rod 4, a third support rod 5, a first ground mat 6, a second ground mat 7, a U-shaped bolt 12, and a support tile 13. The positioning block 1 is a rectangular arc-shaped sleeve with two rotating shafts 16 controlled by torsion springs for reset rotation inside. The inner arc surface is a seedling support surface, and two strip-shaped grooves 18 are provided on the seedling support surface along the arc direction. Five rolling wheels 23 are arranged and installed at the opening of each strip-shaped groove 18. The support tile 13 is fixedly installed on the outer arc surface of the positioning block 1. The cross-sectional structure of the connecting block 2 is aligned with that of the positioning block 1. The two connecting blocks 2 are respectively installed at both ends of the positioning block 1 with one end fitted into the positioning block 1, forming a continuous arc shape with the positioning block 1. The fitting end of the connecting block 2 inside the positioning block 1 is connected to the positioning block 1 by a traction strap 17 that is connected to and wound around the rotating shaft 16. Metal magnetic strips 15 are fixedly embedded on the connecting ends of the connecting blocks 2 that are exposed outside the positioning block 1. The exposed magnetic poles of the metal magnetic strips 15 installed on the two connecting blocks 2 on the same positioning block 1 are opposite in order. Insertion holes 19 are respectively opened at the ends of the connecting ends of the connecting blocks 2.The first support rod 3 is a rigid straight rod in the shape of a plate, with a pull-out sleeve 8 on the rod. A limiting guide groove 11 penetrating the rod is formed on the first support rod 3 at the lower part of the pull-out sleeve 8. One end of the first support rod 3 is hinged to the support tile 13, and the other end is hinged to the first floor mat 6. The second support rod 4 is a rigid straight cylindrical rod, with a threaded sleeve 9 on the rod. One end is hinged to the first support rod 3, and the other end is hinged to the second floor mat 7. Piercing holes are formed on both the first floor mat 6 and the second floor mat 7. The third... The support rod 5 is a double-rod rigid straight rod. The two rods are respectively positioned on both sides of the second support rod 4. One end is coaxially hinged to the second support rod 4 and connected to the second floor mat 7. The other end is hinged to a connecting screw 24. The connecting screw 24 passes through the limiting guide groove 11 on the first support rod 3 and engages with the limiting nut 21. The limiting nut 21 provides a sliding connection to the first support rod 3, thus forming a composite support rod structure with the first support rod 3, the second support rod 4, and the third support rod 5. During production and use, it can be used in conjunction with the second support rod 4. The expansion and sliding adjustment of the support rod 4 adjusts the connection position between the third support rod 5 and the first support rod 3, expanding the composite structure support rod. Tightening the locking nut 21 locks the connection between the third support rod 5 and the first support rod 3, making the composite structure support rod form a stable triangular frame support structure. This enhances the stability and reliability of the composite structure support rod for supporting forestry seedlings. In non-production use, the third support rod 5 can be slid to retract the composite structure support rod, concentrating the first support rod 3, the second support rod 4, and the third support rod 5 into a unidirectional bundled state. This effectively reduces storage and transportation space occupation and improves utilization efficiency. The four unit components can be combined to form a combined forestry seedling protection frame with composite structure support rods as described in this embodiment. The ends of the connecting blocks 2 on each unit component are sequentially connected to form a closed loop 10. The two inserts of the U-shaped bolts 12 are respectively inserted into the insertion holes 19 opened on the connecting blocks 2, connecting the connecting blocks 2 to each other, thereby defining the combined structure of the closed loop 10. Expanding outwards with the four sets of composite structure support rods, the combined support structure of the closed loop 10 can be formed, achieving a balanced support function.

[0020] The specific method for using the combined forestry seedling protective frame with composite structure support rods described in this embodiment in afforestation production is as follows:

[0021] According to the afforestation production, the required number of unit components in the storage state, such as Figures 4 to 6As shown, the integrated loading and transportation to the planting site involves taking four unit components for each forestry seedling, attaching the seedling support surfaces of the positioning blocks 1 on each unit component to the seedling, and sequentially aligning the ends of the connecting blocks 2. Using the magnetically opposite metal strips 15 embedded on the ends, they attract each other to form a closed ring 10 around the seedling. After adjusting the shape of the closed ring 10, the connecting blocks 2 are connected by inserting U-shaped plugs 12 into the insertion holes 19 on the connecting blocks 2, thus defining the closed ring 10. The four first support rods 3 on the 10 extend outwards from the closed ring 10. The lengths of each support rod 3 are adjusted using the pull-out sleeve 8 until a balanced support structure is formed. Then, the connection end of the third support rod 5 with the first support rod 3 is pulled, causing the third support rod 5 to slide along the limiting guide groove 11 on the first support rod 3. Simultaneously, the second support rod 4 is adaptively rotated relative to the first support rod 3 as the third support rod 5 slides, so that the second support rod 4 and the third support rod 5 form an angle α. The length of the third support rod 5 is dynamically adjusted using the threaded sleeve 9. Figure 7 As shown, the composite support structure formed by the first support rod 3, the second support rod 4, and the third support rod 5 is unfolded to form a triangular frame support structure. After adjusting the triangular frame support structure to suit the slope and unevenness of the ground at the support location, the first ground mat 6 and the second ground mat 7 are laid flat on the ground. Figure 1 As shown, using the drill bit 20 as a connecting structural component, it is inserted into the ground through the drill bit holes opened on the first ground pad 6 and the second ground pad 7 respectively to fix the first support rod 3 and the second support rod 4. Then, the limiting nut 21 is tightened relative to the connecting screw 24 to lock the connection between the third support rod 5 and the first support rod 3, and the triangular frame support structure is fixed, thereby completing the support operation for one forestry seedling. Afterwards, the support operation for all forestry seedlings can be completed by following the above operation steps.
