Description

Technical Field

[0001] This utility model belongs to the field of weed control fabric, specifically relating to a gradient breathable weed control fabric. Background Technology

[0002] Weed control fabric is an environmentally friendly, biodegradable material that suppresses weeds and maintains soil moisture. To better adapt to plant growth, it often incorporates ventilation holes to improve its breathability. However, existing breathable weed control fabrics have a fixed and unchangeable breathability, failing to meet the varying breathability requirements of plants at different growth stages. Therefore, a gradient breathable weed control fabric is needed to address these technical issues. Summary of the Invention

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a gradient breathable weed control fabric, comprising a fabric body and a fixing part fixed around the fabric body. The fabric body is provided with multiple layers, and the multiple layers of the fabric body are evenly covered with breathable holes, with the breathable holes of adjacent fabric bodies being staggered vertically.

[0004] Preferably, the outer periphery of the fabric is provided with a connecting part, and the fabric is connected to the fixing part through the connecting part.

[0005] Preferably, gaps are provided between adjacent fabric sections. The presence of gaps ensures airflow and guarantees the breathability of the weed control fabric.

[0006] Preferably, support columns are provided between adjacent fabric layers, with the lower end of each support column connected to the lower fabric layer. Multiple support columns are evenly distributed across the fabric. The support columns can be made of foam, and the supporting portion provides support to the upper fabric layer, effectively maintaining the gaps and ensuring air circulation.

[0007] Preferably, the fixing part has multiple connecting surfaces arranged in a stepped pattern, and the number of connecting surfaces is the same as the number of fabric layers. Each fabric layer is connected to a corresponding connecting surface. This arrangement minimizes the impact on the lower fabric layers when the upper fabric layer is torn off, ensuring that each fabric layer does not affect the others.

[0008] Preferably, the connecting part is connected to the connecting surface by adhesive. The connecting part is covered with through holes, which reduces the adhesive area between the connecting part and the connecting surface, making it easier to tear off the corresponding fabric.

[0009] Preferably, the fabric is biodegradable hemp fiber, polylactic acid (PLA) fiber, or polyhydroxyalkanoate (PHA) fiber.

[0010] Preferably, the fixing part is provided with a plurality of fixing holes, and the fixing holes are fitted with ground nails.

[0011] Working principle: By setting up multiple layers of fabric with staggered air vents between adjacent layers, a zigzag airflow is created. When increased air permeability is needed, the top layer of fabric is torn off, reducing airflow resistance. This achieves gradient air permeability, meeting the air permeability requirements of plants at different stages, thus promoting plant growth.

[0012] This invention also includes other components that enable the normal use of a gradient breathable weed control fabric, all of which are conventional techniques in the field. Furthermore, devices or components not specified in this invention, such as the fabric body, ground stakes, adhesive, and ventilation holes, all employ conventional techniques and equipment in the field.

[0013] The beneficial effects of this utility model are: simple and reasonable structure, which can reasonably control the air permeability of the weed control cloth according to the growth of plants, achieve gradient air permeability, simple operation, and strong practicality.

[0017] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0018] Example 1 like Figure 1 , 2As shown in Figures 4 and 5, this utility model provides a gradient breathable weed control fabric, including a fabric body 3 and a fixing part 1 fixed around the fabric body 3. The fabric body 3 is provided with multiple layers, and the multiple layers of fabric body 3 are evenly covered with breathable holes 4. The breathable holes 4 of adjacent fabric bodies 3 are staggered vertically.

[0019] The fabric body 3 is provided with a connecting part 5 on its periphery, and the fabric body 3 is connected to the fixing part 1 through the connecting part 5.

[0020] A gap 6 is provided between adjacent fabric pieces 3. The presence of the gap 6 ensures airflow and the breathability of the weed control fabric.

[0021] Support columns 7 are provided between adjacent fabric pieces 3. The lower end of the support column 7 is connected to the lower fabric piece 3, and multiple support columns 7 are evenly distributed on the fabric pieces 3. The support columns 7 can be made of foam, and the supporting parts provide support to the upper fabric pieces 3, effectively maintaining the gap 6 and ensuring air circulation.

[0022] The fabric body 3, as well as the connecting and fixing parts, can all be made of degradable hemp fiber, polylactic acid (PLA) fiber, or polyhydroxyalkanoate (PHA) fiber. The connecting part 5 is covered with through holes 8. The through holes 8 reduce the strength of the connecting part 5, making it easier to tear off the corresponding fabric body 3.

[0023] The fixing part 1 is provided with a plurality of fixing holes, and the fixing holes are fitted with ground nails 2.

[0024] Example 2 like Figure 1 , 3 The difference between this embodiment and Embodiment 1 is that the fixing part 1 has multiple connecting surfaces, which are distributed in a stepped manner. The number of connecting surfaces is the same as the number of fabric bodies 3, and the fabric bodies 3 are connected to the corresponding connecting surfaces. This arrangement facilitates the removal of the upper fabric body 3 while minimizing the impact on the lower fabric body 3, ensuring that each layer of fabric body 3 does not affect the others.

[0025] The connecting part 5 is connected to the connecting surface by adhesive. The connecting part 5 is covered with through holes 8. The through holes 8 reduce the adhesive area between the connecting part 5 and the connecting surface, making it easier to tear off the corresponding fabric 3.
