Description

Technical Field

[0001] The utility model relates to the field of forest seedling protection, in particular to a unit component combined forest seedling support and protection frame. Background Art

[0002] In afforestation production, newly planted forest seedlings are fragile and have poor environmental adaptability. They are easily affected by external environmental factors and damaged or destroyed, affecting their normal growth and development. For example, wind, gravity or human factors are very likely to cause forest seedlings to fall over or tilt. The falling and tilting of forest seedlings can not only directly damage the root system of the seedlings, hinder the growth of seedlings and even cause the death of seedlings, but the chaotic and tilted growth state may also destroy the tree shape of adult trees, and have a profound harmful effect on the natural ecological environment. Therefore, in production, it is usually necessary to support and protect the newly planted forest seedlings to ensure their normal development and healthy growth. The utility model patent with authorization announcement number CN222030781U discloses "a forestry seedling protection device", which is composed of a fixed seat, a rotating frame and a support plate. Although the clamping effect of the support plate can be used to support the seedlings in production applications to prevent the seedlings from tipping over, and to support and protect the forest seedlings, since the device is an integrated three-dimensional structure based on the fixed seat, the fixed seat has a large specification, the rotating frame is long and is irregularly connected to the fixed seat, which makes the overall space occupancy too large. When the afforestation area is large and the number of devices required is large, it will undoubtedly significantly increase the transportation cost of transfer and the labor intensity of handling, thereby increasing production input and reducing utilization efficiency. At the same time, the fixed seat with a circular ring structure limits the minimum spacing of forest seedlings. Therefore, when the planting spacing of forest seedlings is less than the ring diameter of the fixed seat, the device cannot be used. The existence of the above problems seriously restricts the promotion and application of forest seedling support and protection devices in the field of large-scale afforestation production. Therefore, it is necessary to study and improve the tree seedling support and protection device in the existing technology, optimize the structure, improve the function, and solve the existing technical problems. Utility Model Content

[0003] The purpose of the utility model is to provide a unit component combined forest seedling support and protection frame, optimize the structure, improve the function, improve the support operation efficiency and support and protection effect of the forest seedlings, expand the scope of promotion and use, and ensure the healthy growth of the forest seedlings.

[0004] A unit component combined forest seedling support and protection frame, which is composed of unit components as basic unit combinations; the unit components include: a positioning block, a connecting block and a support rod, the positioning block and the connecting block are arc-shaped bodies with the same curvature, the two connecting blocks are respectively connected and installed at the two ends of the positioning block and form a continuous arc shape with the positioning block, the inner arc surface of the positioning block is the seedling support surface, the seedling support surface protrudes from the inner arc surface of the connecting block, and can form a corresponding support cooperation with the forest seedlings, the support rod is a rigid straight rod body, one end of which is hingedly connected to the outer arc surface of the positioning block, and the other end is hingedly connected to a ground pad , a dowel connection hole is opened on the ground pad, and the dowel can be used to lock and fix the ground pad on the ground; at least 3 of the unit components are used in combination with each other, and the ends of the connecting blocks on each of the unit components are connected in sequence and connected to each other in a detachable manner to form a closed ring body with the positioning blocks evenly distributed along the circumference, and the closed ring body can be used to clamp and restrain the planted tree seedlings. At the same time, the support rods are coordinated to expand to the outside of the closed ring body and are fixedly connected to the ground using the ground pad to form a combined support structure, which balances and supports the closed ring body to ensure the vertical growth of the tree seedlings and implements tilt protection for the tree seedlings.

[0005] The unit component combined forest seedling support and protection frame, preferably the positioning block is a rectangular sleeve with a cross-sectional structure corresponding to the connecting block, and is connected to the connecting block in a ring sleeve manner. A rotating shaft is installed inside the sleeve of the positioning block and a torsion spring is installed in cooperation. The torsion spring is supported between the positioning block and the rotating shaft, and applies a rotational reset torque to the rotating shaft relative to the positioning block. One end of the pulling belt is connected and wound around the rotating shaft, and the other end is fixedly connected to the connecting block. Under the action of the torsion spring, the pulling belt is respectively relative to the positioning block. Keeping the corresponding elastic pulling on the connecting block, the coordinated action of the connecting block can make the closed ring body generate an inward elastic contraction force and at the same time have a moderate range of freedom of diameter increase and expansion, so that the closed ring body can adaptively increase in diameter and expand outward as the diameter of the forest seedlings grows in a supported state, while keeping the seedling support surface on the positioning block always dynamically fitted with the forest seedlings, ensuring the stability of the supporting support for the forest seedlings, without the need to manually adjust the aperture of the closed ring body during the growth of the forest seedlings, thereby improving the afforestation production efficiency and reducing the labor intensity of workers.

[0006] Preferably, rolling wheels are arranged on the seedling support surface on the inner side of the positioning block, and the rolling wheels are evenly arranged on the seedling support surface. Each rolling wheel has a rotational freedom along the circumferential direction of the closed ring section, so that the seedling support surface can balance the support of the forest seedlings in a rolling contact manner between the rolling wheels and the forest seedlings. When the diameter of the forest seedlings increases as the tree diameter increases, the diameter of the closed ring body adaptively increases accordingly. The seedling support surface contacts and cooperates with the forest seedlings in a rolling state through the rolling wheels, and the sliding cooperation state between the seedling support surface and the forest seedlings can significantly reduce the friction resistance, which is beneficial to ensure the free growth of the forest seedlings, while also avoiding damage or destruction to the epidermis of the forest seedlings caused by sliding friction, thereby increasing the planting survival rate of the forest seedlings and ensuring the healthy growth of the forest seedlings.

[0007] Preferably, it also includes: a U-shaped plug, and insertion holes are respectively opened at the end heads of the connection ends of the connecting blocks connected to each other, and the structures of the insertion holes and the U-shaped plugs correspond to each other, so that after the end faces of the connecting blocks on the two unit components are butted against each other, the two insertion rods on the U-shaped plug are respectively inserted into the insertion holes opened on the two connecting blocks to achieve the mutual connection between the two connecting blocks, and conversely, the two connecting blocks can be separated from each other by pulling out the U-shaped plug, and the disassembly and assembly procedures are simple and easy to operate.

[0008] Preferably, metal magnetic strips are fixedly embedded on the end faces of the connecting ends of the connecting blocks, and the polarities of the magnetic poles exposed on the end faces of the connecting ends of the connecting blocks on both sides of the unit components are opposite to each other, so that when the unit components are combined, the connecting blocks can pre-assemble the closed ring body through the mutual attraction between the metal magnetic strips on the end faces, thereby reducing the difficulty of subsequent insertion of the U-shaped plugs to connect the connecting blocks to each other, reducing labor intensity and improving work efficiency.

[0009] Preferably, a pull-out sleeve that can be pulled out to adjust its length is provided on the support rod, so that during production and use, the setting height of the closed ring body can be appropriately adjusted by changing the length of the support rod according to the height of the seedlings, or the balance and stability of the closed ring body space setting can be ensured by setting different length combinations of the support rod according to the slope and uneven conditions on the ground, thereby expanding the use function and improving the adaptability and reliability of production applications.

[0010] The beneficial effect of the utility model is to provide a unit component combined forest seedling support and protection frame, which is composed of standardized unit components as basic unit combinations. Each unit component can be folded and stored into a relatively regular structural state, which is conducive to integrated loading and transportation, fully saves loading space, and significantly reduces transportation costs. It can well meet the conditions for the industrialization and promotion of large-scale afforestation production. Moreover, the support rods on each unit component in production applications can be staggered without hindrance to each other, and there is no limit on the planting spacing of forest seedlings. It has good production versatility and process adaptability, can well solve the problems of the existing technology, and promote the transportation of forest seedlings. The promotion and application of support and protection devices in the field of large-scale afforestation production ensures the healthy growth of forest seedlings and improves the survival rate of afforestation; further, the combined structure of the positioning block and the connecting block is optimized, the connection method is innovated, the assembly procedure is simplified, and the overall reliability of the combined structure is enhanced. At the same time, the hoop support function of the closed ring body is improved. On the basis of setting the initial elastic contraction force, the diameter increase and outward freedom of the closed ring body are increased to ensure that the positioning block is always dynamically fitted with the forest seedlings, thereby improving the stability of the support and protection of the forest seedlings. When applied to actual production, it can improve the support operation efficiency, reduce the labor intensity of workers, and ensure the forest protection effect. BRIEF DESCRIPTION OF THE DRAWINGS
