Description

Technical Field

[0001] This utility model relates to the field of afforestation technology, specifically a marking device for tending young forests in afforestation areas. Background Technology

[0002] Young forest tending refers to various technical measures taken during the young forest stage to improve the survival and retention rates of afforestation, promote the growth of saplings, and accelerate forest canopy closure. Newly planted young forests, especially in the first few years after planting, often have small trees, shallow root systems, slow growth, and are susceptible to various adverse environmental factors, resulting in unstable survival and growth. Therefore, timely implementation of appropriate tending measures to continuously eliminate interference from adverse factors is of great significance for improving the quality of afforestation and consolidating afforestation results.

[0003] The utility model patent with authorization publication number CN221899694U discloses a marking device for tending young forests in afforestation areas, including mounting plate a and mounting plate b, and also includes an elastic fixing device installed on mounting plate a and mounting plate b for the seedlings to continue to surround the trunk body after growth.

[0004] However, the above technical solution has the following drawbacks: the device adapts to tree growth through an elastic layer and elastic band, but long-term stretching may lead to material aging and breakage. Furthermore, the marking box is fixed below the elastic layer by a threaded rod, making it impossible to adjust the observation angle. In summary, this device faces the risk of long-term loss of adaptability due to the aging and breakage of key component materials, and the problem of poor long-term observation results due to the fixed observation angle of the marking box.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0044] Example 1 is as follows.

[0045] like Figures 1 to 2 As shown, this utility model is a marking device for tending young forests in afforestation areas, including a telescopic buckle arm and a universal marking device installed on the telescopic buckle arm.

[0046] To improve the practicality of the device, the retractable buckle arms are arc-shaped and there are three of them. The three retractable buckle arms are connected end to end to form an approximately circular ring structure so that they can be fitted onto the tree trunk.

[0047] The telescopic buckle arm includes an inner slide rail 101 and an outer slide rail 102, and also includes a locking device mounted on the outer slide rail 102;

[0048] A serrated pad 103 is fixedly provided on the surface of the inner slide rail 101 facing the tree trunk so that it can fit tightly against the tree trunk, increase the friction with the tree trunk, prevent the device from sliding on the tree trunk, and avoid damage caused by rigid contact between the inner slide rail 101 and the tree trunk.

[0049] The outer slide rail 102 has a threaded hole on the surface away from the trunk.

[0050] Preferably, the inner slide rail 101 and the outer slide rail 102 are made of ultra-high molecular weight polyethylene (UHMWPE). This material has a low coefficient of friction and self-lubricating properties, enabling smooth sliding without oil lubrication; its wear resistance and weather resistance meet the requirements for long-term outdoor use. Within the applicable thickness range of the inner slide rail 101 (e.g., approximately 5 mm to 150 mm), UHMWPE possesses the toughness to withstand the arc-shaped straightening deformation caused by tree growth while maintaining the mechanical component functions required for structural stability. Furthermore, UHMWPE can be machined into complex structural features such as ratchet teeth and threaded holes through conventional machining, ensuring the practicality of the inner slide rail 101 and the outer slide rail 102 as functional components.

[0051] Preferably, the pad 103 is made of silicone. This material is lightweight and easy to process. It has anti-slip properties and is not easily damaged on the contact surface; its abrasion resistance and weather resistance meet the requirements for long-term outdoor use.

[0052] To improve the practicality of the device, in the installed state, two adjacent telescopic buckle arms are detachably connected by hook-type buckle 104 and hanging ring-type buckle 105.

[0053] The hook-type buckle 104 is fixedly installed on the telescopic end of the inner slide rail 101;

[0054] The hanging ring buckle 105 is fixedly installed at the opposite end of the outer slide rail 102.

[0055] To improve the stability of the device, guide grooves 106 are provided on the lower surface of the top wall and the upper surface of the bottom wall of the outer slide rail 102.

[0056] The limiting block 107 is fixedly installed at the end of the guide groove 106 and is located at the same end as the hook-type buckle 104;

[0057] The guide key 108 is fixedly installed at the end of the inner slide rail 101 and is located at the same end as the hanging ring buckle 105;

[0058] The guide key 108 has an extension that slides into the guide groove 106 to ensure that the inner slide rail 101 slides correctly along the outer slide rail 102.

[0059] To improve the practicality of the device, the locking device includes a ratchet 109, a pin 110, a pawl 111, a torsion spring 112, an arc-shaped guide groove 113, and a push rod 114.

[0060] The ratchet 109 is fixedly disposed on the surface of the inner slide rail 101 facing the outer slide rail 102;

[0061] The pin 110 is fixedly installed on the bottom wall of the outer slide rail 102 facing the inner slide rail 101;

[0062] Pawl 111 is hinged to pin 110;

[0063] Torsion spring 112 is sleeved on pin 110;

[0064] The arc-shaped guide groove 113 is provided on the top of the outer slide rail 102;

[0065] The push rod 114 is fixedly mounted on the upper surface of the pawl 111 at the end away from the pin 110 and is exposed through the arc-shaped guide groove 113 so that the push rod 114 can be operated on the top of the outer slide rail 102.

[0066] To improve the practicality of the device, one end of the torsion spring 112 is fixed to the side of the pawl 111 away from the pin 110, and the other end is fixed to the side wall of the outer slide rail 102 facing the inner slide rail 101.

[0067] Under the action of the torsion spring 112, the pawl 111 engages with the tooth groove of the ratchet 109, ensuring that the inner slide rail 101 can only slide outward and not inward, thus achieving locking.

[0068] To improve the practicality of the device, the center of the arc-shaped guide groove 113 coincides with the center of the pin 110.

[0069] Guided by the arc-shaped guide groove 113, the push rod 114 rotates around the pin 110, thereby causing the pawl 111 to rotate around the pin 110 to disengage from or engage with the tooth groove of the ratchet 109.

[0070] When the trunk diameter needs to be accommodated, the inner slide rail 101 automatically slides outward under the pressure of the trunk, the pawl 111 disengages from the tooth groove of the ratchet 109, and the inner slide rail 101 slides to a position that adapts to the trunk diameter. When the pressure on the trunk stops, the pawl 111 automatically engages with the new tooth groove of the ratchet 109 under the action of the torsion spring 112, achieving dynamic adjustment and locking to prevent the device from jamming the trunk.

[0071] When it is necessary to accommodate a smaller diameter tree trunk, push the push rod 114. The pawl 111 disengages from the ratchet tooth 109, and the inner slide rail 101 is manually slid inward until it reaches the appropriate trunk diameter. Release the push rod 114, and the pawl 111, under the action of the torsion spring 112, resets and engages with the new ratchet tooth 109, achieving graded adjustment and locking to prevent the device from slipping off the tree trunk.

[0072] To improve the practicality of the device, the universal marking device includes a ball seat 201, a ball head 202, a threaded rod A203, a threaded rod B204, and a marking body (not shown in the figure).

[0073] Ball seat 201 is mounted on one or more outer slide rails 102 on the surface away from the trunk;

[0074] The ball head 202 is interference-fitted into the spherical groove provided in the ball seat 201;

[0075] Both ends of the threaded rod A203 and threaded rod B204 have external threads on their outer cylindrical surfaces;

[0076] The ball seat 201 has a first threaded hole on its surface;

[0077] The ball head 202 has a second threaded hole on its surface;

[0078] One end of the threaded rod A203 is threaded to the first threaded hole of the ball seat 201, and the other end is threaded to the threaded hole of the outer slide rail 102.

[0079] One end of the threaded rod B204 is threaded to the second threaded hole of the ball head 202, and the other end is threaded to the marking body.

[0080] When it is necessary to ensure that the marker is within the preset viewing angle range, first loosen the threaded rod A203 to release the ball head 202 to adjust the viewing angle of the marker, and then tighten the threaded rod A203 to lock the ball head 202 to fix the viewing angle of the marker.

[0081] When it is necessary to install the marker, simply screw the marker into the threaded rod B204.

[0082] When the marker needs to be replaced, simply unscrew the marker from the threaded rod B204.

[0083] Example 2 is as follows.

[0084] Based on Embodiment 1, this embodiment further optimizes the structure of the universal marking device.

[0085] A universal marking device and a marking body installed on the universal marking device are provided on the surface of each outer slide rail 102 away from the trunk, forming a multi-directional marking system.

[0086] When displaying the same tree information simultaneously from different directions, expand the coverage area of ​​the tree information.

[0087] Increase the richness of tree information when displaying different tree information in different directions simultaneously.

[0088] Furthermore, the number of retractable locking arms can be adjusted according to the actual situation. For example, for trees with extra-large diameters, four or more retractable locking arms can be used to form a larger ring structure.

[0089] In summary, this utility model, by fitting the device onto the trunk of a young tree, utilizes the double-slide rail structure of the telescopic buckle arm and the locking device to achieve dynamic and graded adjustment and locking, adapting to changes in diameter at breast height from young to mature trees; and uses a universal marking device in conjunction with the threaded rod A203 to adjust the ball head 202 to adjust the observation angle of the marking body, ensuring that the marking body is within the preset viewing angle range.

[0090] The technical solution of this utility model has been further described above with reference to the accompanying drawings and embodiments, but this utility model is not limited thereto. Those skilled in the art can make modifications and improvements without departing from the scope of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
