Abstract
Description
Technical Field
[0001] This utility model relates to the field of ancient tree restoration technology, specifically to a structure for filling and restoring tree cavities in ancient trees. Background Technology
[0002] Ancient trees, as precious natural heritage and witnesses to history and culture, bear significant ecological, cultural, and scientific value. However, due to natural factors (such as wind and rain erosion, lightning strikes, and pests) and human factors (such as collisions and scratches), ancient trees often develop tree cavities. These cavities not only disrupt the overall structural stability of the tree but also provide breeding grounds for pests and pathogens, accelerating its decay and death. Currently, most common tree cavity restoration methods on the market have limitations. Traditional restoration methods often use elastic ropes for initial fixation when filling tree cavities. However, these ropes are prone to elasticity failure due to aging and tensile fatigue over long-term use, leading to their fall and inability to provide stable support for subsequent filling materials, thus affecting the restoration effect. Moreover, traditional filling materials have a single function, focusing only on the physical filling of the tree cavity and lacking effective protection against pest erosion. After restoration, pests may continue to erode the healthy tissue around the tree cavity, causing it to enlarge and rendering the restoration work futile. Therefore, it is essential to develop a new structure for filling and restoring ancient tree cavities. Utility Model Content
[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a structure for filling and repairing ancient tree cavities, which can solve the above problems.
[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: The structure for filling and restoring the cavity of an ancient tree includes a sealing layer, a filling sphere bonded to the surface of the sealing layer, a soft plastic ring fixedly installed around the sealing layer, two binding ropes on one side of the soft plastic ring with several fixing holes evenly spaced on the surface of the binding ropes, two sleeves on the other side of the soft plastic ring with locking bolts threaded to the outside of the sleeves, the binding ropes wrapping around the outside of the ancient tree with the ends of the binding ropes passing through the inside of the sleeves, the locking bolts being embedded and connected to the fixing holes of the binding ropes, and the filling spheres being embedded in the cavity of the ancient tree.
[0005] Furthermore, the filling sphere has an internal cavity, is filled with insect repellent solid agent, and has an end cap that is snapped onto the end of the filling sphere. The end cap has several through holes on its surface.
[0006] Furthermore, two hanging rings are fixedly installed on one side of the soft plastic ring, and a matching ring is fixedly installed at one end of the binding rope, which is connected to the hanging ring.
[0007] Furthermore, the diameter of the fixing hole is larger than the thread diameter of the locking bolt by mm, and the distance between two adjacent fixing holes is set to 4mm~8mm.
[0008] Furthermore, the binding rope is a nylon braided rope, and a stainless steel ring is fitted inside the fixing hole.
[0009] Furthermore, the thickness of the soft plastic ring is twice the thickness of the sealing layer, and the sealing layer is located in the middle of the soft plastic ring.
[0010] The beneficial effects of this utility model are as follows: the binding rope of this application device is tightened with the locking bolt of the sleeve after one week, which facilitates the repair of tree holes within the rope size range. The binding rope does not use an elastic rope, which can avoid the situation where the elastic rope fails and falls off. The filling ball fills the tree hole, and the filling ball is equipped with an insect repellent solid agent to prevent pests from further eroding the tree hole, which helps the ancient tree hole to self-repair and grow.

[0017] Example 1: The sealing layer 1 can be made of waterproof and breathable fabric. The soft plastic ring 2 and the hanging ring 5 are both made of TPU material. The matching ring 601 is made of stainless steel. After the matching ring 601 is set with an opening and hung with the soft plastic ring 2, the opening of the matching ring 601 is welded closed to ensure the connection stability. The size of the filling ball 3 is customized according to the size of the tree hole 11 of the ancient tree 10. The filling ball 3 is slightly smaller than the size of the tree hole 11. The filling ball 3 is fixed to the surface of the sealing layer 1 by adhesive. After the filling ball 3 is filled with insect repellent solid agent 9, the top cap 4 is put on. The molecules released by the insect repellent solid agent 9 can be released from the through hole 401 to repel insects. The insect repellent solid agent 9 is a tree trunk whitewash, which is made by mixing quicklime, sulfur powder, salt, oil and other ingredients to make a solid paste. It is dried into a ball shape and put into the filling ball 3. At the same time, a layer of tree trunk whitewash diluted with water can be applied to the inner wall of the tree hole to enhance the insect control of the tree hole.

The mating ring 601 is hooked to the hanging ring 5. After the mating ring 601 is hooked to the soft plastic ring 2 with an opening, the opening of the mating ring 601 is welded closed to ensure the connection stability.
[0020] In the preferred technical solution, the diameter of the fixing hole 602 is 2mm larger than the thread diameter of the locking bolt 8, ensuring that the locking bolt 8 can smoothly enter the fixing hole 602. The distance between two adjacent fixing holes 602 is set to 4mm~8mm, which can improve the adjustment accuracy.
[0021] In the preferred technical solution, the binding rope 6 is a nylon braided rope, and a stainless steel ring is fitted inside the fixing hole 602. The stainless steel ring has strong tear resistance, which can extend the service life of the binding rope 6.
[0022] In the preferred technical solution, the thickness of the soft plastic ring 2 is twice the thickness of the sealing layer 1, and the sealing layer 1 is located in the middle of the soft plastic ring 2, which is conducive to the soft plastic ring 2 adhering to the surface of the tree.
