Description

Technical Field

[0001] This utility model belongs to the field of landscape engineering technology, specifically relating to a fixing structure under a transplanted tree. Background Technology

[0002] From propagation to planting, trees may undergo one or more transplanting processes. Transplanting can be a cultivation measure before planting, changing the planting distance or growing environment of the plant so that trees that have grown to a certain stage can obtain sufficient nutrition, light and air, or gradually adapt to the environmental conditions of planting. At the same time, the taproot of the seedling can be cut off during transplanting as needed, which will encourage the seedling to produce more lateral roots and form a well-developed root system, which will benefit the seedling growth and provide favorable conditions for future transplanting and planting.

[0003] Currently, tree transplantation often involves manual digging and planting using simple tools such as shovels. To increase mechanization and reduce labor, mechanical devices for transplantation are constantly being developed, replacing manual labor with mechanical power, effectively reducing labor intensity and increasing production efficiency. However, simply replacing manual labor with mechanical power and using shovel-like equipment for transplanting still has drawbacks. It can break up the soil near the tree roots, causing the roots to separate from the soil and altering the soil environment the roots have adapted to. At the same time, during the process of removing soil clumps, a large number of hairy roots and fine roots are torn off, causing root damage. Even if the new planting hole is filled with soil of the same type, it will still have a significant negative impact on the tree's growth and may even significantly reduce the survival rate of transplanted trees.

[0004] Based on the above-mentioned existing technology, this utility model proposes a tree transplanting tree fixing structure to partially solve the above problems. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a tree transplanting fixation structure, which solves the problems that, although existing tree transplanting has developed devices that use mechanical power to replace manual labor, mechanical equipment similar to shovels still has defects such as breaking the soil near the tree roots, separating the roots from the soil, tearing off a large number of fine roots and causing root damage, thus affecting the survival rate of transplanted trees.

[0006] The objective of this utility model can be achieved through the following technical solution: a tree transplanting and fixing structure, comprising a ground anchor assembly and a cable assembly. The ground anchor assembly includes at least three ground anchor rods, which are distributed in an equilateral triangle at the bottom of the soil pit. Each ground anchor rod consists of a rod body, a chamfered hook, and a pull ring. The lower end of the rod body is movably connected to the middle of the chamfered hook through a hinge shaft. The chamfered hook has a sharp chamfered end, which is used to open outward and embed into the soil when the rod body is lifted to enhance the pull-out resistance of the ground anchor rod. The upper end of the rod body is integrally formed with the pull ring. The cable assembly includes a polyester webbing and a tensioner. The polyester webbing passes through the pull ring and surrounds the surface of the tree's root ball. The tensioner connects the two ends of the polyester webbing for tightening and fixing.

[0007] As a preferred embodiment of this utility model, the width of the polyester webbing is 5-10cm and the tensile strength is ≥5000N.

[0008] As a preferred embodiment of this utility model, the tensioner is a ratchet tensioner or a lever tensioner.

[0009] As a preferred technical solution of this utility model, the lower end of the rod body is provided with a positioning protrusion, which cooperates with the positioning groove in the middle of the chamfered hook shovel; the hinge shaft includes a shaft body that passes through the positioning groove and the positioning protrusion laterally, and anti-detachment limiting components are provided at both ends of the shaft body.

[0010] As a preferred technical solution of this utility model, the anti-detachment limiting component is a threaded fastening cap, which is adapted to the threaded sections at both ends of the shaft body.

[0011] As a preferred technical solution of this utility model, the chamfered hook shovel is made of iron steel metal material.

[0012] As a preferred embodiment of this utility model, the sharp end of the chamfered hook is set with a triangular included angle.

[0013] The beneficial effects of this utility model are as follows: the ground anchors distributed in equilateral triangles form a stable three-dimensional force-bearing structure; the inclined angle design of the chamfered hook shovel allows it to open outward and embed into the soil when the rod is lifted, significantly enhancing pull-out resistance; the cooperation between the hinge shaft and the positioning protrusion and groove enables precise positioning and controllable opening of the chamfered hook shovel, ensuring stability and uniform force during installation; the polyester webbing, combined with a ratchet or lever-type tightener, wraps around the soil ball to tighten it, avoiding damage to the tree trunk, while providing uniform constraint force and improving the tree's resistance to lodging after transplantation; the ground anchors are easy to install, reusable, and reduce maintenance costs, meeting the requirements of green construction and effectively ensuring the survival rate and growth stability of transplanted trees.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Please see Figure 1-2 This embodiment provides a fixed structure under a tree for transplanting. From the process of propagation to planting, trees may be transplanted once or multiple times. Transplanting can be used as a cultivation measure before planting. Although existing tree transplanting has developed devices that use mechanical power to replace human labor, mechanical equipment such as shovels still have defects such as breaking the soil near the tree roots, separating the roots from the soil, tearing off a large number of hair roots and fine roots, causing root damage, and thus affecting the survival rate of transplanted trees.

[0019] To address the aforementioned problems, this embodiment proposes a tree transplanting and fixing structure, including a ground anchor assembly and a cable assembly. The ground anchor assembly includes at least three ground anchor rods, which are distributed in an equilateral triangle at the bottom of the soil pit, forming a stable three-dimensional force-bearing structure. Each ground anchor rod consists of a rod body 100, a chamfered hook 200, and a pull ring 300. The lower end of the rod body 100 is movably connected to the middle of the chamfered hook 200 via a hinge shaft 101. The chamfered hook 200 has a chamfered hook tip 201, which is used to open outward and embed into the soil when the rod body 100 is lifted, thereby enhancing the pull-out resistance of the ground anchor rod. Simultaneously, the upper end of the rod body 100 and the pull ring 300 are integrally formed. Specifically, the lower end of the rod body 100 is connected to the middle of the chamfered hook 200 via a hinge shaft 101, allowing the chamfered hook 200 to rotate around the axis, forming an expandable structure. The chamfered hook 200 forms a preset angle with the rod 100, and the sharp end 201 of the chamfered hook 200 faces the inside of the rod 100, making it easy to drive into the soil. The sharp end 201 of the chamfered hook is set with a triangular angle, with an angle of 30°-60°. The angle makes the sharp end form a wedge-shaped structure, and the inclined force can squeeze the soil to one side, reducing the resistance to soil penetration. When the rod 100 is lifted, the inclined end generates a lateral thrust on the soil, forcing the hinge shaft 101 of the chamfered hook 200 to open outward, forming the anchoring effect of the chamfer.

[0020] The aforementioned cable assembly includes a polyester webbing and a tensioner. The polyester webbing passes through a loop 300 and wraps around the surface of the tree's root ball. The tensioner connects both ends of the polyester webbing for tightening and securing it. The polyester webbing, combined with a ratchet or lever-type tensioner, tightens around the root ball, preventing damage to the trunk while providing uniform restraint and improving the tree's resistance to lodging after transplantation.

[0021] It should be noted that in the fixing structure under the transplanted tree, the recessed pit at the bottom of the soil hole is the key foundation for the accurate installation and stable force bearing of the ground anchor. In this embodiment, the pit is mainly designed with a depth of 10cm and an area of ​​20cm×20cm. The positioning groove function allows the ground anchor to be accurately positioned in an equilateral triangle layout, avoiding uneven force and the risk of collapse caused by positional deviation. At the same time, the stable support surface formed by the bottom of the pit and the surrounding soil can limit the shaking and deviation of the ground anchor when it is driven in, maintain the preset angle between the chamfered hook 200 and the rod body 100, and ensure the reliability of the subsequent expansion and embedding of the hook into the soil, laying the foundation for the stability and pull-out resistance of the overall fixing structure.

[0022] In this embodiment, the width of the polyester webbing is 5-10cm, the tensile strength is ≥5000N, and the tensioner is a ratchet type tensioner or a lever type tensioner.

[0023] In this embodiment, a positioning protrusion is provided on the inner side of the lower end of the rod body 100, which cooperates with the positioning groove in the middle of the chamfered hook shovel 200; its hinge shaft 101 includes a shaft body that passes through the positioning groove and the positioning protrusion laterally, and anti-detachment limiting components are provided at both ends of the shaft body; the anti-detachment limiting component is a threaded fastening cap, which is adapted to the threaded sections at both ends of the shaft body.

[0024] In this embodiment, the chamfered hook 200 is made of iron steel rod metal material, which is mostly high carbon steel or alloy steel, with a tensile strength of up to 600-1000MPa and a yield strength of ≥355MPa. It can maintain structural stability without bending or breaking when driven into the soil and withstood thousands of Newtons of hammer impact force and thousands to tens of thousands of Newtons of pull-out force when lifted. Its surface hardness reaches HRC40-55, and the wear resistance of the sharp end is significantly improved. It can be reused. With hot-dip galvanizing or chrome plating, it can be used in soil environment for 5-10 years without being corroded.

[0025] This embodiment describes a tree transplanting and fixing structure that uses ground anchor cables to firmly secure the tree's root ball in the ground, thereby fixing the tree upright and preventing it from falling over. The process sequence is as follows: excavating the pit → driving in anchor bolts → threading the cable webbing → lowering the tree → tightening the webbing → backfilling with planting soil. After excavating the root ball pit, the three corner points of an equilateral triangle with the largest area are marked inside the pit. The soil at these three corner points is then shoveled down to approximately 10cm below the bottom of the pit, with each point having an area of ​​approximately 20×20cm. The chamfered hook tip 201 of the chamfered hook shovel 200 is placed against the corner point. A hammer is used to strike the pull ring 300, driving the ground anchor bolt into the soil at the triangle point. Then, the ground anchor bolt is pulled upwards, causing the chamfered hook tip 201 to expand and increasing the bolt's pull resistance. Thread the polyester webbing through the anchor bolt loop 300mm and leave some slack. Use a crane to lift the tree and adjust it to a vertical position. Then, slowly place the root ball into the hole and hang the webbing that has been threaded onto the root ball. Then, tighten the webbing initially, adjust the tree's position, and finally tighten the webbing with a tensioner.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
