Description

Technical Field

[0001] This utility model relates to the field of landscape greening engineering technology, and in particular to a root protection and fixing device for transplanted garden trees. Background Technology

[0002] In modern urban landscaping projects, large tree transplantation has become a common construction method to quickly create a scenic effect. The key to successful tree transplantation lies in the integrity of the "root ball." The root ball not only encloses the tree's main root system but also stores the water and symbiotic microorganisms necessary for the tree's survival. Therefore, protecting the root ball from loosening and cracking during excavation, transportation, and hoisting is the core challenge of transplantation work.

[0003] However, current techniques for tree transplantation typically involve securing the root ball with straw ropes or plastic bags. While straw ropes offer some ventilation, their binding strength is often insufficient during long-distance transport or heavy machinery lifting, easily leading to root breakage. Plastic bags or ordinary woven bags, while providing better water retention, must be removed before planting; otherwise, they hinder root growth. Upon removal, the previously compacted root ball easily collapses in the planting pit due to the loss of external support, causing severe secondary damage. Furthermore, existing wrapping methods lack standardized rigid support points; during lifting, steel cables often directly constrict the root ball or trunk neck, easily causing bark girdling damage and severely impacting the tree's later growth and recovery.

[0004] Therefore, this utility model proposes a root system protection and fixing device for transplanted garden trees to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the transplanting of garden trees, such as the root ball being easily loose and broken, insufficient binding force of traditional wrapping methods, secondary damage caused by removing the wrapping material during planting, easy damage to the tree trunk during hoisting, and low survival rate due to difficulty in precise irrigation of deep roots, this utility model aims to provide a garden tree transplanting root protection and fixing device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a root protection and fixing device for transplanted garden trees, including: an inner lining mechanism and a protective sleeve mechanism. The inner lining mechanism covers the outer periphery of the root ball of the tree, and the protective sleeve mechanism is fitted over the inner lining mechanism.

[0007] The inner lining mechanism has a layered wrapping structure, specifically including a hydrophobic plate, a non-woven fabric, and a fiber web. The hydrophobic plate abuts against the bottom of the soil ball, the non-woven fabric wraps the hydrophobic plate and the side of the soil ball, and the fiber web is wrapped and fixed to the outside of the non-woven fabric. The sheath mechanism specifically includes a fixing shell and a fixing component. The fixing shell is joined to form a receiving cavity, and the inner lining mechanism is filled in the receiving cavity.

[0008] Furthermore, the fixing component, the fixing shell, and the inner lining mechanism are combined by a mechanical locking engagement. Specifically, the fixing component includes a female buckle, a male buckle, and a bolt. The female buckle is fixed to the outer edge of the fixing shell, and the male buckle is fixed to the outer edge of the fixing shell. The female buckle and the male buckle are engaged, and there is a threaded hole aligned vertically between the female buckle and the male buckle. The bolt is screwed into the threaded hole and locked, thereby tightly encapsulating the inner lining mechanism and the soil ball inside the fixing shell.

[0009] Preferably, both the nonwoven fabric and the fiber web are made of biodegradable materials, and the bolt is equipped with a nut at the bottom. After the bolt passes through the threaded hole, it is fixed by the nut to ensure the stability of the locking structure.

[0010] Preferably, the sheath mechanism further includes protective cotton, which is placed at the connection between the root ball and the tree trunk, and extends upward along the tree trunk to a specified height. The top of the fixing shell covers the outside of the protective cotton to prevent the hard shell from damaging the bark.

[0011] Preferably, a reinforcing rib is fixed to the outside of the fixed shell. The reinforcing rib is used to connect the lifting rope. The lifting force is distributed by the reinforcing rib, so as to avoid direct force on the soil ball or the tree trunk.

[0012] Preferably, a fertilizer storage tank pipe is fixed to the outside of the fixed shell, and the fertilizer storage tank pipe has a cavity inside to contain nutrients. The fertilizer storage tank pipe is used to release nutrients into the soil ball to meet the nutritional needs during the transplanting process.

[0013] Preferably, it also includes a water guide pipe, which is disposed inside the fixed shell and extends to the soil ball. The top of the water guide pipe is provided with a water inlet, which protrudes a certain size from the ground to achieve precise irrigation of the deep root system.

[0014] Preferably, the water pipe is detachably connected to the fixed shell, and the water pipe is left in the soil after the fixed shell is removed in order to continuously supply water.

[0015] Preferably, the fixing shell is a semi-circular shell structure, and there are two fixing shells. When the fixing shells are closed together, they enclose the inner lining mechanism to form a standardized cylindrical or spherical module.

[0016] Preferably, the mating surfaces of the female buckle and the male buckle are respectively provided with a groove and a protrusion. The female buckle and the male buckle are positioned by the groove and the protrusion to improve the alignment accuracy during assembly.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of loose and broken root balls and difficult lifting in the prior art by adopting a double-layer structure design that combines an inner lining mechanism and a protective sleeve mechanism. It achieves the effect of encapsulating irregular root balls into standardized rigid modules, which greatly improves the safety and construction efficiency in the transplanting process.

[0019] 2. This utility model solves the problem of the traditional plastic bag wrapping needing to be removed during planting, which leads to secondary collapse of the soil ball and damage to the roots. It achieves the effect of planting without removing the inner lining and without disturbing the root system, thus effectively improving the survival rate of transplanted trees.

[0020] 3. This utility model solves the problem that surface water cannot penetrate and roots cannot obtain sufficient water because the roots of newly transplanted trees are buried deep, by setting a detachable water pipe between the sheath mechanism and the soil ball. It achieves the effect of precise irrigation of deep roots and induces the roots to grow downward.

[0021] 4. This utility model solves the problem of bark damage or soil ball deformation caused by the direct binding of the hanging rope to the trunk or soil ball during traditional transplanting by setting a reinforcing rib with a lifting hole on the outside of the fixed shell. It achieves the effect of scientifically transferring the lifting force point and protecting the tree body from mechanical damage. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Reference Figures 1 to 4 This utility model provides a root protection and fixing device for transplanted garden trees, aiming to solve the technical problems of root damage, rapid water loss, and difficulty in hoisting existing garden tree transplantation methods due to the easy loosening of the root ball.

[0034] like Figure 1 As shown, it includes an inner lining mechanism 3 and a protective sleeve mechanism 4 fitted outside the inner lining mechanism 3. The inner lining mechanism 3 tightly wraps around the root ball 2 at the base of the tree to prevent the root ball 2 from loosening and to retain soil moisture. The protective sleeve mechanism 4 serves as a rigid support structure to provide mechanical protection for the sealed root ball 2 during hoisting and transportation. The two work together to form a standardized transplanting module that is flexible inside and rigid outside, which greatly improves the transplant survival rate and construction efficiency. The inner lining mechanism 3 specifically includes a water-draining plate 31, a non-woven fabric 32, and a fiber mesh 33.

[0035] Reference Figure 1The drainage plate 31 is abutted against the bottom of the root ball 2 to support the root ball 2 and prevent water accumulation and root rot. The non-woven fabric 32 is wrapped around the drainage plate 31 and the outer surface of the side wall of the root ball 2 to retain moisture and prevent the loss of fine soil. The fiber mesh 33 is tightly wrapped around the outside of the non-woven fabric 32 to further reinforce the root ball 2 and prevent it from becoming loose. Both the non-woven fabric 32 and the fiber mesh 33 are made of biodegradable materials and do not need to be removed after transplanting, avoiding secondary soil disturbance and root damage. The sheath mechanism 4 includes two semi-cylindrical or hemispherical fixing shells 41. The two fixing shells 41 are joined together to form a receiving cavity. The inner lining mechanism 3 is filled and contained in the receiving cavity. Fixing components 46 are provided on both sides of the fixing shells 41. The two adjacent fixing shells 41 are detachably rigidly connected through the fixing components 46, thereby encapsulating the root ball 2 as a whole.

[0036] Reference Figure 4 The fixing component 46 includes a female buckle 461, a male buckle 462, and a bolt 463. The female buckle 461 is fixedly connected to one side edge of one fixing shell 41, and the male buckle 462 is fixedly connected to the corresponding side edge of the other fixing shell 41. The female buckle 461 has a groove structure, and the male buckle 462 has a protrusion structure that matches the groove structure. The female buckle 461 and the male buckle 462 achieve initial positioning and engagement through the cooperation of the groove structure and the protrusion structure. At this time, the pre-set threaded holes on the female buckle 461 and the male buckle 462 are coaxially aligned. The bolt 463 passes through the coaxially aligned threaded hole and is threadedly fastened to the matching nut, thereby achieving a tight lock between the two fixing shells 41 and ensuring that the shells will not separate during the hoisting process.

[0037] The sheath mechanism 4 also includes protective cotton 45, which is set at the connection between the root ball 2 and the tree trunk 1. The protective cotton 45 extends upward along the surface of the tree trunk 1 to a specified height. The inner wall of the neck at the top of the fixing shell 41 is tightly fitted to the outer side of the protective cotton 45. The cushioning effect of the protective cotton 45 effectively prevents the fixing shell 41 from damaging the tree bark when it is shaken under force. The outer wall of the fixing shell 41 is integrally formed or fixedly connected with reinforcing ribs 42. The reinforcing ribs 42 extend along the height direction or arc direction of the fixing shell 41 to enhance the shell's compressive strength. The upper part of the reinforcing ribs 42 is provided with lifting holes or hooks for passing through lifting ropes, so that the lifting force is applied to the reinforcing ribs 42 rather than directly to the root ball 2, thus avoiding deformation of the root ball 2 under force.

[0038] The outer wall of the fixed shell 41 is fixedly connected to a fertilizer storage tank pipe 43. The axis of the fertilizer storage tank pipe 43 is parallel to the height direction of the fixed shell 41. It has a cavity for containing nutrients. The bottom of the fertilizer storage tank pipe 43 has a material guide channel that connects to the cavity for slowly releasing nutrients into the soil ball 2. It also includes a water guide pipe 44. The water guide pipe 44 is inserted between the inner lining mechanism 3 and the sheath mechanism 4, or directly inserted into the soil ball 2. The bottom end of the water guide pipe 44 extends to the bottom area of ​​the soil ball 2, and its top end extends out of the top of the fixed shell 41 and exposes the water inlet. The water guide pipe 44 and the fixed shell 41 are connected by a detachable snap-fit ​​or plug-in connection so that the water guide pipe 44 can be left independently in the soil when the fixed shell 41 is removed.

[0039] The implementation principle of this application embodiment is as follows: When garden trees need to be transplanted, first determine the size of the root ball 2 and after trimming the root system, use non-woven fabric 32 to wrap and fix the drainage board 31 to the bottom of the root ball 2. Then, use fiber mesh 33 to further tightly wrap and fix the root ball 2. The inner lining mechanism 3 effectively prevents the root ball 2 from losing moisture and the soil from falling off, and guides the roots to grow healthily outward. Next, wrap the protective cotton 45 from the connection between the root ball 2 and the trunk 1 upward along the trunk 1. Then, use the sheath mechanism 4 to wrap the two fixing shells 41 around the outside of the inner lining mechanism 3, align the fixing components 46 on both sides, so that the female buckle 461 and the male buckle 462 are tightly closed and aligned with the threaded holes. Screw in the bolt 463 and lock it. At this time, a solid module is formed at the root of the tree.

[0040] The suspension ropes are then fixed to the reinforcing ribs 42, and the trees are moved to the transport vehicle using a crane. If necessary, the prepared nutrients are placed in the fertilizer storage tank pipe 43. The trees are transported to the planting site and hoisted into the pit for a certain period of time. After that, the fixing component 46 is removed, and only the fixing shell 41 and the fixing component 46 are taken out and recycled, while the inner lining mechanism 3 and the water pipe 44 are left in the soil. At this time, the water inlet at the top of the water pipe 44 protrudes a certain size from the ground. The maintenance personnel can slowly replenish water to the bottom of the soil ball 2 through the water inlet to achieve precise deep irrigation, promote the root system to grow downwards, and achieve full protection from digging, transportation to the early stage of planting.
