Abstract
Description
Technical Field
[0001] The present application relates to the field of ecological technology, and in particular to an ecological bag. Background Art
[0002] Eco bags are an important part of the flexible ecological slope engineering system. Eco bags have a targeted filtering function that is water-permeable but not soil-permeable. They are very plant-friendly and allow plants to grow freely through the bag. However, existing eco bags are not only low in strength and short in service life, but also have limited water retention capacity of the greening substrate in the bag, which often causes water shortage in the growth process of plant seeds. In places where eco bags are most needed, there is usually a lack of water, which results in a low germination rate of plant seeds and a less than ideal greening effect. Utility Model Content
[0003] The embodiment of the present application provides an eco-bag with a simple structure, which can be beneficial to the growth and development of plant seeds in the eco-bag.
[0004] An embodiment of the present application provides an eco-bag, which includes a bag body made of a water-permeable and breathable material, the inner cavity of the bag body is provided with a pulp layer, a seed layer and a first water-retaining agent layer, the pulp layer is connected to the inner wall circumference of the bag body, the seed layer and the first water-retaining agent layer are arranged above the pulp layer, and the pulp layer is used to support the seed layer and the first water-retaining agent layer; wherein a plurality of grooves are formed on the upper surface of the pulp layer, and at least a portion of the plant seeds in the seed layer are located in the grooves.
[0005] In this solution, the bag body is made of a water-permeable and breathable material, so that rainwater and air outside the eco-bag can communicate with the inside of the bag body, which is beneficial to the growth and development of plant seeds in the bag body. By arranging a pulp layer, a seed layer and a first water-retaining agent layer in the inner cavity of the bag body, the pulp layer can provide a bearing function for the seed layer and the first water-retaining agent layer during the transportation and transfer stage of the eco-bag, and the first water-retaining agent layer can play a water-retaining function. After the external water enters the bag body, a part of the water will be absorbed by the first water-retaining agent layer, providing a more lasting water supply for the plant seeds. More importantly, by forming a groove on the pulp layer, on the one hand, in the early germination stage of the plant seeds, the groove is equivalent to a very small water storage pit, which not only has a certain water storage function, but also can play a role in lasting partial wetting of the plant seeds, which is more conducive to the germination of the plant seeds and also improves the survival rate of the plants. On the other hand, the grooves can play a certain limiting role for plant seeds. During the transportation and transfer of the eco-bag, the plant seeds are not prone to clustering, which makes the distribution of plant seeds on the pulp layer relatively more even, which is more conducive to the growth and development of plant seeds and also improves the survival rate of plants.
[0006] In some embodiments, a plurality of grooves are distributed in an array on the upper surface of the pulp layer.
[0007] In the above technical solution, by evenly distributing the plurality of grooves in an array in the pulp layer, the grooves are distributed more evenly, and accordingly, the plant seeds in the seed layer are distributed more evenly.
[0008] In some embodiments, the cross-sectional shape of the groove is semicircular.
[0009] In the above technical solution, by adopting the shape of the fiber groove as a semicircle, the plant seeds can be distributed in the groove.
[0010] In some embodiments, the plant seeds in the seed layer are evenly adhered to the upper surface of the pulp layer by water-soluble glue, and at least part of the plant seeds are located in the grooves.
[0011] In the above technical scheme, the plant seeds are evenly adhered to the upper surface of the pulp layer with water-soluble glue, so that the plant seeds can be more evenly distributed on the pulp layer. The water-soluble glue can provide a certain initial fixation effect for the seeds. Compared with scattering the plant seeds on the pulp layer, it avoids the phenomenon of plant seeds clumping and uneven distribution during the transfer and transportation of the eco-bag, which affects the subsequent growth and development of the plants.
[0012] In some embodiments, the bag body includes a top wall and a bottom wall that are relatively distributed, and the first water-retaining agent layer is filled in a first containing space formed between the pulp layer and the top wall; the ecological bag also includes a second water-retaining agent layer, and the second water-retaining agent layer is located in a second containing space formed between the lower surface of the pulp layer and the bottom wall.
[0013] In the above technical solution, by arranging a second water-retaining agent layer in the second containing space, when the plant seeds are in the early stage, the second water-retaining agent layer is arranged, the roots of the plant seeds can directly pass through the pulp layer and enter the second water-retaining agent layer below the pulp layer, providing the roots of the plant seeds with the water required for growth, reducing the survival difficulty of the plant seeds and improving the survival rate of the plant seeds.
[0014] In some embodiments, the eco-bag further includes a planting soil layer, and the planting soil layer and the second water retaining agent layer are mixed and filled in the second containing space.
[0015] In the above technical solution, by filling the bag body with a planting soil layer and a second water-retaining agent layer, the planting soil layer and the second water-retaining agent layer can provide certain nutrients and water in the early stage of plant seeds. Especially in the early stage of plant seeds, the setting of the planting soil layer and the second water-retaining agent layer does not require the root system of the plant seeds to penetrate the bag body and enter the soil after taking root and germination. Instead, the root system of the plant seeds can directly pass through the pulp layer and enter the planting soil layer and the second water-retaining agent layer below the pulp layer, providing nutrients and water to the plant seeds, reducing the difficulty of survival of the plant seeds and improving the survival rate of the plant seeds.
[0016] In some embodiments, a degradable film layer is attached to the inner wall of the bag body, and the material of the film layer is thermoplastic biodegradable plastic.
[0017] In the above technical solution, a film layer is attached to the inner wall of the bag body. When the eco-bag is placed on the slope, although the film layer is not in direct contact with the soil, the film layer is arranged on one side of the inner surface of the bag body. After the eco-bag is placed on the soil, it is equivalent to the film layer covering the surface of the soil. The film layer covering the surface of the soil can improve the soil structure, soil temperature, soil moisture and soil air permeability, improve the microbial activity in the soil, and is conducive to the growth and development of plant seeds in the bag body. After the film layer is degraded, it will not pollute the environment.
[0018] In some embodiments, the membrane layer is provided with holes at intervals.
[0019] In the above technical solution, since the film layer covers one side of the inner surface of the bag body, it has a certain water barrier before the film layer is degraded. Therefore, by opening holes in the film layer, the holes can allow external water and air to pass through and enter the inner cavity of the bag body, providing moisture to the plant seeds in the seed layer, which is beneficial to the rooting and germination of the plant seeds.
[0020] In some embodiments, a reinforcement layer is provided on one side of the outer surface of the bag body. The material of the reinforcement layer is glass fiber or nylon. The reinforcement layer is sewn on one side of the outer surface of the bag body in a grid pattern.
[0021] In the above technical solution, a reinforcement layer is provided on the outer surface of the bag body, and the reinforcement layer is sewn on one side of the outer surface of the bag body in a grid pattern, which is equivalent to forming a spaced stiffening rib or reinforcing rib structure on the outer side of the bag body, which can provide a certain reinforcement effect on the outer peripheral side of the bag body and extend the service life of the eco-bag. The material of the bag body is glass fiber or nylon, which can be sewn on the outer surface of the bag body more conveniently, which is easy to process and easy to implement.
[0022] In some embodiments, the bag body is made of polyester fiber.
[0023] In the above technical solution, the bag body is made of polyester fiber, which has the advantages of being water-permeable, air-permeable and soil-impermeable, and can allow external rainwater and air to communicate with the inside of the bag body, which is beneficial to the growth and development of plant seeds in the seed layer in the bag body, while avoiding the leakage of the water-retaining agent layer in the bag body. In addition, the polyester fiber bag body can prevent UV ultraviolet rays, high temperature and low temperature, strong weather resistance, long service life, and can better ensure the growth and development of plants in the eco-bag for a long period of time.
[0024] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example
[0036] This application embodiment provides an eco-bag, please refer to Figure 1 , Figure 2 and Figure 3 The eco-bag 100 includes a bag body 10 made of a water-permeable and breathable material. The inner cavity of the bag body 10 is provided with a pulp layer 20, a seed layer 30 and a first water-retaining agent layer 40. The pulp layer 20 is connected to the inner wall circumference of the bag body 10. The seed layer 30 and the first water-retaining agent layer 40 are arranged above the pulp layer 20. The pulp layer 20 is used to carry the seed layer 30 and the first water-retaining agent layer 40; wherein, a plurality of grooves 21 are formed on the upper surface of the pulp layer 20, and at least a part of the plant seeds in the seed layer 30 are located in the grooves 21.
[0037] In this solution, by making the bag body 10 of a water-permeable and air-permeable material, rainwater and air outside the eco-bag 100 can communicate with the inside of the bag body 10, which is beneficial to the growth and development of plant seeds in the bag body 10. By arranging the pulp layer 20, the seed layer 30 and the first water-retaining agent layer 40 in the inner cavity of the bag body 10, the pulp layer 20 can provide a bearing function for the seed layer 30 and the first water-retaining agent layer 40 during the transportation and transfer stage of the eco-bag 100, and the first water-retaining agent layer 40 can play a water-retaining function. After the external water enters the bag body 10, part of the water will be absorbed by the first water-retaining agent layer 40, providing a more lasting water supply for the plant seeds. More importantly, by forming a groove 21 on the pulp layer 20, on the one hand, in the early germination stage of the plant seeds, the groove 21 is equivalent to a small water storage pit, which not only has a certain water storage function, but also can play a lasting partial wetting function for the plant seeds, which is more conducive to the germination of the plant seeds and also improves the survival rate of the plants. On the other hand, the groove 21 can play a certain limiting role for the plant seeds. During the transportation and transfer of the ecological bag, the plant seeds are not easy to be clustered, so that the distribution of the plant seeds on the pulp layer 20 is relatively more uniform, which is more conducive to the growth and development of the plant seeds and also improves the survival rate of the plants.
[0038] The groove 21 can be formed by pressing a pressing plate, and a plurality of convex parts are correspondingly protruded on the pressing plate. When the pressing plate presses the upper surface of the pulp layer 20 and the pressing plate presses the pulp layer 20 downward, a plurality of grooves 21 are formed on the pulp layer 20. The groove depth of the groove 21 can be 0.1 mm-0.8 mm, and the groove depth of the groove 21 is related to the thickness of the pulp layer 20, and the groove depth of the groove 21 can be between one fifth and three fifths of the thickness of the pulp layer 20.
[0039] During the transportation of the eco-bag 100 or when the seeds are laid on the pulp layer 20 , not all the plant seeds in the seed layer 30 can be sprinkled in the groove 21 , so some of the plant seeds can be in the groove 21 and some of the plant seeds are located outside the groove 21 on the pulp layer 20 .
[0040] In some embodiments, the plurality of grooves 21 are distributed in an array on the upper surface of the pulp layer 20. By evenly distributing the plurality of grooves 21 in an array on the pulp layer 20, the grooves 21 are distributed more evenly, and accordingly, the plant seeds of the seed layer 30 are distributed more evenly.
[0041] The plurality of grooves 21 may be distributed in a rectangular array, a circular array, a plum blossom shape, or an irregular distribution on the upper surface of the pulp layer 20, depending on the actual situation. Optionally, the plurality of grooves 21 may be distributed in a plum blossom shape on the surface of the pulp layer 20.
[0042] The number of plant seeds in the groove 21 can be one, two or more. Of course, the number of plant seeds in the groove 21 is related to the size of the groove 21, or the density of the groove 21 arranged on the pulp layer 20. It is more appropriate that the number of plant seeds in the groove 21 is one or two.
[0043] In some embodiments, the cross-sectional shape of the groove 21 is semicircular. By adopting the shape of the fiber groove 21 as a semicircle, plant seeds can be distributed in the groove 21.
[0044] Among them, different plant seeds have different shapes, so the shape of the groove 21 is not limited to a semicircle. For example, the shape of the groove 21 can also be a strip groove, a square groove or a triangular groove, etc., depending on the actual situation.
[0045] In some embodiments, the plant seeds in the seed layer 30 are evenly attached to the upper surface of the pulp layer 20 by water-soluble glue, and at least part of the plant seeds are located in the groove 21. By evenly attaching the plant seeds to the upper surface of the pulp layer 20 by water-soluble glue, the plant seeds can be more evenly distributed on the pulp layer 20, and the water-soluble glue can provide a certain initial fixation effect for the seeds. Compared with scattering the plant seeds on the pulp layer 20, it avoids the phenomenon of plant seeds clumping and uneven distribution during the transfer and transportation of the eco-bag, which affects the subsequent growth and development of the plants.
[0046] After the eco-bag 100 is arranged on the slope protection, rainwater enters the eco-bag and combines with the water-soluble glue, which will cause the water-soluble glue to disperse and cancel the adhesive effect on the plant seeds, which is beneficial to the rooting and germination of the plant seeds.
[0047] In some embodiments, the bag body 10 includes a top wall 11 and a bottom wall 12 that are relatively distributed, and the first water-retaining agent layer 40 is filled in the first accommodation space formed between the pulp layer 20 and the top wall 11; the eco-bag also includes a second water-retaining agent layer 50, and the second water-retaining agent layer 50 is located in the second accommodation space formed between the lower surface of the pulp layer 20 and the bottom wall 12. By arranging the second water-retaining agent layer 50 in the second accommodation space, in the early stage of plant seeds, the second water-retaining agent layer 50 is arranged, and the root system of the plant seeds can directly pass through the pulp layer 20 and enter the second water-retaining agent layer 50 below the pulp layer 20, providing the root system of the plant seeds with the water required for growth, reducing the survival difficulty of the plant seeds and improving the survival rate of the plant seeds.
[0048] In some embodiments, the eco-bag 100 further includes a planting soil layer 51, and the planting soil layer 51 and the second water-retaining agent layer 50 are mixed and filled in the second containing space. By filling the bag body 10 with the planting soil layer 51 and the second water-retaining agent layer 50, the planting soil layer 51 and the second water-retaining agent layer 50 can provide certain nutrients and water in the early stage of plant seeds. In particular, in the early stage of plant seeds, the setting of the planting soil layer 51 and the second water-retaining agent layer 50 does not require the plant seeds to penetrate the bag body 10 and enter the soil after taking root and germination. Instead, the roots of the plant seeds can directly pass through the pulp layer 20 and enter the planting soil layer 51 and the second water-retaining agent layer 50 below the pulp layer 20, providing nutrients and water to the plant seeds, reducing the difficulty of survival of the plant seeds and improving the survival rate of the plant seeds.
[0049] Among them, since the pulp layer 20 has a certain water absorption capacity, the pulp layer 20 will expand, the gaps will become larger, it will wrinkle, and even spread out after being soaked in water. In this way, during the germination stage, the roots of plant seeds can easily pass through the pulp layer 20 and extend into the planting soil layer 51, thereby reducing the survival difficulty of plant seeds and correspondingly improving the survival rate of plant seeds.
[0050] In some embodiments, a degradable film layer 60 is attached to the inner wall of the bag body 10, and the material of the film layer 60 is thermoplastic biodegradable plastic. By attaching a film layer 60 to the inner wall of the bag body 10, when the eco-bag is placed on the slope, although the film layer 60 is not in direct contact with the soil, the film layer 60 is arranged on one side of the inner surface of the bag body 10. After the eco-bag is placed on the soil, it is equivalent to the film layer 60 covering the surface of the soil. The film layer 60 covering the surface of the soil can improve the soil structure, soil temperature, soil moisture and soil air permeability, improve the microbial activity in the soil, and is conducive to the growth and development of plant seeds in the bag body 10. After the degradation of the film layer 60, there is no pollution to the environment.
[0051] The film layer 60 is made of thermoplastic biodegradable plastic with a degradation period of 6 months.
[0052] In some embodiments, holes are provided at intervals in the film layer 60. Since the film layer 60 covers one side of the inner surface of the bag body 10, it has a certain water barrier before the film layer 60 is degraded. Therefore, by providing holes in the film layer 60, the holes can allow external water and air to penetrate into the inner cavity of the bag body 10, provide moisture to the plant seeds in the seed layer 30, and facilitate the rooting and germination of the plant seeds.
[0053] In some embodiments, a reinforcement layer 70 is provided on one side of the outer surface of the bag body 10. The reinforcement layer 70 is made of glass fiber or nylon. The reinforcement layer 70 is sewn on one side of the outer surface of the bag body 10 in a grid-like shape. By providing a reinforcement layer 70 on the outer surface of the bag body 10, and sewing the reinforcement layer 70 on one side of the outer surface of the bag body 10 in a grid-like shape, it is equivalent to forming a spaced stiffening rib or reinforcing rib structure on the outer side of the bag body 10, which can provide a certain reinforcement effect on the outer peripheral side of the bag body 10 and extend the service life of the eco-bag. The material of the bag body 10 is glass fiber or nylon, which can be sewn on the outer surface of the bag body 10 more conveniently, which is convenient for processing and easy to implement.
[0054] In some embodiments, the bag body 10 is made of polyester fiber. By using polyester fiber as the bag body 10, the bag body 10 made of polyester fiber material has the advantages of being water-permeable, air-permeable and soil-impermeable, and can allow external rainwater and air to communicate with the inside of the bag body 10, which is beneficial to the growth and development of plant seeds in the seed layer 30 in the bag body 10, while avoiding leakage of the water-retaining agent layer in the bag body 10. In addition, the bag body 10 of polyester fiber can prevent UV ultraviolet rays, high temperature and low temperature, strong weather resistance, long service life, and can better ensure the growth and development of plants in the eco-bag 100 for a long period of time.
[0055] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
[0056] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
