Description

Technical Field

[0001] This utility model relates to the field of covering netting technology, specifically a green, environmentally friendly, and biodegradable dense mesh netting for green plants. Background Technology

[0002] In the fields of engineering construction and ecological restoration, environmental protection and water conservation measures must be taken for temporary stockpiles of construction waste and exposed surfaces after slope excavation to control dust spread and reduce soil erosion, in accordance with relevant regulations such as the "Environmental Protection and Water Conservation Management Measures for Construction Projects". Currently, the mainstream covering measures mainly rely on the following two types of materials: non-degradable materials, such as polyethylene (PE) plastic netting and polypropylene (PP) dustproof netting, which may not be recycled in time after the project is completed; and traditional vegetation materials, such as turf rolls and planting bags, which can achieve long-term vegetation protection, but require separate laying of dustproof netting in the early stage, resulting in the problem of repeated construction of "covering the netting first and then planting grass", and the transportation cost of turf rolls is high.

[0003] Currently, there are some combinations of "biodegradable netting + grass seeds", but most of them simply spray grass seeds on the surface of the netting or attach them to the mesh with glue. The former makes it easy for grass seeds to fall off during transportation and laying, while the latter uses glue that is mostly non-biodegradable. Furthermore, the grass seeds are concentrated on the surface of the netting and are easily pecked by birds, resulting in a low germination rate. Therefore, this application designs a dense green netting with a stable structure, reliable grass seed fixation, and synergistic matching between degradation and vegetation growth. Utility Model Content

[0004] The purpose of this invention is to provide a green, environmentally friendly, and biodegradable dense mesh net for greening plants, in order to solve the problems mentioned in the background art, such as the grass seeds not being firmly fixed when simply sprayed on the net surface and the low germination and survival rate of the grass seeds when glue is applied to the mesh.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a green and environmentally friendly biodegradable dense mesh net for plants, comprising a net body, wherein the net body includes a functional rope body one and a functional rope body two, the net body being woven from multiple strands of functional rope body one and functional rope body two in a warp and weft interlacing manner, and the edges of the net body being provided with a reinforcing structure; the functional rope body one and functional rope body two are arranged identically, the functional rope body one including a covering outer core filament, a covering inner core filament, and a seed liner, the covering outer core filament, the covering inner core filament, and the seed liner being arranged layer by layer from the outside to the inside, the covering outer core filament and the covering inner core filament being both made of PLA composite yarn twisted together, the seed liner being embedded inside the covering inner core filament, and the seed liner being distributed along the length direction of the covering inner core filament.

[0006] Preferably, the main body of the mesh is in the shape of a rectangular sheet, and a rectangular grid is formed between the first functional rope and the second functional rope.

[0007] Preferably, the inner core filament is made of pure PLA, and the outer core filament is a blend of PLA and bamboo fiber, comprising one-fifth of the material.

[0008] Preferably, the seed liner is provided at equal intervals along the length of functional rope body one or functional rope body two, and the seed liner includes a grass seed layer and a slow-release fertilizer mold covering the grass seed layer, wherein the grass seed layer is composed of several grass seeds.

[0009] Preferably, the reinforcing structure includes an upper bonding layer and a lower bonding layer, which are sandwiched at the edge of the mesh body. Both the upper and lower bonding layers are made of PLA material and are fixed by heat fusion at their contact surfaces.

[0010] Preferably, the upper and lower bonding layers are provided with equally spaced fixing holes surrounding the main body of the mesh.

[0011] Preferably, a photodegradation promoter is added to the mesh body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The entire mesh body is made of biodegradable materials, which have good compatibility with the soil environment after degradation. The mesh body can be completely degraded to reduce pollution. The seeds are fixed inside the inner core wires, rather than on the surface, which reduces the shedding of grass seeds during transportation and laying, and also makes them less likely to be pecked by birds. The slow-release fertilizer continuously releases nutrients, and the outer and inner core wires retain moisture, which improves the germination rate.

[0014] 2. By tightly bonding the upper and lower pressing layers to the edge of the mesh body, the reinforcement structure and the mesh body form an integrated structure, which effectively improves the tear resistance of the mesh body edge. Using biodegradable fixing piles through the fixing holes can effectively fix the mesh body, reduce the impact of external wind force, and enhance the stability during use.

[0021] 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.

[0022] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a green and environmentally friendly biodegradable dense mesh net for plants, including a net body 1. The net body 1 includes functional rope one 11 and functional rope two 12. The net body 1 is woven from multiple strands of functional rope one 11 and functional rope two 12 in a warp and weft interlacing manner. The edge of the net body 1 is provided with a reinforcing structure 2. Functional rope one 11 and functional rope two 12 are arranged in the same manner. Functional rope one 11 includes an outer core filament 111, an inner core filament 112, and a seed liner 113. The outer core filament 111, the inner core filament 112, and the seed liner 113 are arranged layer by layer from the outside to the inside. The filaments 112 are all made of PLA composite filaments twisted together. The seed liner 113 is embedded inside the inner core filament 112 and is distributed along the length of the inner core filament 112. The entire mesh body 1 is made of biodegradable material, which has good compatibility with the soil environment after degradation. The mesh body 1 is completely biodegradable. The seed liner 113 is fixed inside the inner core filament 112 rather than on the surface, which reduces the shedding of grass seeds during transportation and laying and makes them less likely to be pecked by birds. The slow-release fertilizer mold 1132 continuously releases nutrients, which, together with the outer core filament 111 and the inner core filament 112, retains moisture and improves the germination rate of the grass seed layer 1131.

[0023] Although the cost of PLA composite yarn is slightly higher than that of traditional plastic yarn, the integrated weaving process eliminates the need for later mesh recycling and secondary planting, thus reducing the overall cost throughout the entire lifecycle.

[0024] The main body of the mesh 1 has a rectangular sheet structure. A rectangular grid is formed between functional rope 11 and functional rope 2 12. The mesh aperture is designed and distributed reasonably to provide sufficient space for plant growth and effectively prevent the loss of larger soil particles. The intersection of functional rope 11 and functional rope 2 12 is fixedly connected by hot-melt bonding, which enhances the structural stability of 1 and avoids the rust and pollution problems that may be caused by using traditional metal connectors.

[0025] The inner core filament 112 is made of pure PLA, while the outer core filament 111 is a blend of PLA and bamboo fiber, which accounts for one-fifth of the material. The pure PLA inner core filament 112 has excellent mechanical and biodegradability properties and can provide stable structural support. The PLA and bamboo fiber blended outer core filament 111 retains the biodegradable properties of PLA and enhances the air permeability and water absorption of the outer core filament 111 through the addition of bamboo fiber. During use, it can better regulate the soil microenvironment and promote the growth and development of the grass seed layer 1131 in the seed liner 113.

[0026] The seed liner 113 is equidistantly spaced along the length of the functional rope body 11 or the functional rope body 12. The seed liner 113 includes a grass seed layer 1131 and a slow-release fertilizer mold 1132 covering the grass seed layer 1131. The grass seed layer 1131 is composed of grass seeds, which can ensure the initial vitality of green plant growth. The slow-release fertilizer mold 1132 is made of natural starch-based material. Its interior is evenly distributed with nutrients such as nitrogen, phosphorus, and potassium required for plant growth. It can be slowly decomposed in the soil through the action of microorganisms, continuously providing nutrients for the germination of the grass seed layer 1131 and the growth of seedlings. This avoids the nutrient loss and environmental pollution problems that may be caused by traditional fertilizers, and also reduces the manual input of later maintenance.

[0027] Photodegradation accelerators are added to the main body 1 of the mesh, which can absorb light of specific wavelengths and trigger chemical reactions, accelerating the degradation process of the main body 1 in the natural environment. When the mesh is laid on the outdoor soil surface, after a certain period of light exposure, the molecular chains of the main body 1 will gradually break, causing its structural strength to gradually decrease, and eventually decompose into harmless small molecules that are incorporated into the soil. This avoids the soil structure damage and ecological pollution caused by the long-term residue of traditional plastic mesh. A certain proportion of photodegradation accelerators can be added according to the usage scenario. For scenarios that require rapid degradation, the main body 1 can complete large-scale degradation in 30-45 days under natural light. For scenarios that require long-term coverage, such as winter construction, where grass seeds need to germinate the following spring, the degradation cycle of the main body 1 is extended to 60-90 days, ensuring that the main body 1 can still maintain its structural integrity before the grass seeds germinate.

[0028] Please see Figure 1 and Figure 2The reinforcing structure 2 includes an upper pressing layer 21 and a lower pressing layer 22, which are sandwiched at the edge of the mesh body 1. Both the upper pressing layer 21 and the lower pressing layer 22 are made of PLA material. The upper pressing layer 21 and the lower pressing layer 22 are fixed by heat fusion at their interface to form a reinforcing structure 2 surrounding the edge of the mesh body. PLA material has good biodegradability, and its degradation products are also harmless carbon dioxide and water, which will not cause secondary pollution to the environment. The thickness of the upper pressing layer 21 and the lower pressing layer 22 is set to 0.3-0.5mm. They are tightly bonded to the edge of the mesh body 1 through heat fusion process, so that the reinforcing structure 2 and the mesh body 1 form an integrated structure, which effectively improves the tear resistance of the edge of the mesh body 1. During transportation, laying and use, it can avoid premature failure of the mesh body 1 due to edge damage.

[0029] The upper pressing layer 21 and the lower pressing layer 22 have equidistant fixing holes 23 surrounding the mesh body 1, which facilitates the installation and fixing of the mesh body 1. During actual laying, biodegradable fixing stakes can be used to pass through the fixing holes 23 to stably fix the mesh body 1 in the soil at the preset position, effectively preventing the mesh body 1 from shifting or deforming under the action of external forces such as wind, and ensuring that the mesh body 1 can always play a good supporting and protective role during the growth of green plants. The equidistantly distributed fixing holes 23 design makes the force on the mesh body 1 more uniform and enhances its stability.

[0030] Working principle: When in use, the main body of the net 1 is made of functional rope 11 and functional rope 2 12 interwoven with warp and weft. The mesh density ensures large-area coverage. After being laid, it can directly cover the slag heap and exposed slope surface, physically blocking the spread of dust and meeting the immediate protection requirements of environmental protection and water conservation. At the same time, bamboo or PLA fixing stakes can be inserted through the fixing holes 23 located at the edge to fix the main body of the net 1 to the ground or slope, preventing the main body of the net 1 from being blown away in strong winds and ensuring the stability of the coverage.

[0031] After the main body of the netting 1 is laid, when it is naturally rained on or artificially watered, the slow-release fertilizer mold 1132 located outside the grass seed layer 1131 will begin to slowly degrade within a few days, releasing the internal slow-release compound fertilizer to provide initial growth nutrients for the grass seeds. As the grass seed layer 1131 germinates and grows into seedlings, the main body of the netting 1 will gradually degrade. At this time, the main body of the netting 1 and the reinforcing structure 2 are semi-transparent, not blocking sunlight or hindering vegetation growth. The vegetation gradually replaces the main body of the netting 1 as the new cover layer, achieving a match between the degradation of the main body of the netting 1 and the growth rhythm of the grass seed layer 1131; when the grass seed layer 1 When the 131 plant has grown into a turf, the main body of the mesh 1 and the reinforcing structure 2 have been completely degraded. All materials of the main body of the mesh 1 and the reinforcing structure 2 are biodegradable and will not cause secondary pollution. At this time, the vegetation forms a long-term ecological protection layer by fixing the soil with its roots and covering the soil with its stems and leaves. It replaces the main body of the mesh 1 to achieve long-term soil and water loss control and ecological restoration. There is no need to recycle the main body of the mesh 1 later, nor is there a need for secondary construction and grass planting. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
