Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation, and in particular to a drip irrigation strip structure, a drip irrigation strip, and a drip irrigation system. Background Technology

[0002] In the field of agricultural irrigation, the application of drip irrigation technology has made it possible to improve water resource utilization efficiency and precision fertilization.

[0003] However, ordinary drip irrigation tape suffers from uneven water distribution. In a field, some areas have ample water and crops grow well, while others show signs of drought due to insufficient water. This is particularly problematic in undulating terrain, where lower water pressure and slower dripping at higher elevations contrast sharply with higher water pressure and faster dripping at lower elevations, resulting in inconsistent irrigation levels. This uneven water distribution not only leads to inconsistent crop growth, affecting overall yield and quality, but also wastes water resources.

[0004] Furthermore, ordinary drip irrigation tape has limitations in fertilizer application, as it cannot use water-soluble organic fertilizers. In modern agriculture, water-soluble organic fertilizers are highly favored due to their environmental friendliness, high efficiency, and ability to improve soil structure. However, ordinary drip irrigation tape, with its simple internal structure and lack of effective filtration and flow stabilization measures, is prone to clogging when using water-soluble organic fertilizers, affecting the normal operation of the drip irrigation system. This severely restricts farmers' fertilizer choices, preventing them from fully utilizing the advantages of water-soluble organic fertilizers and hindering the improvement of farmland soil quality and the healthy growth of crops.

[0005] Traditional drip irrigation tape has revealed many problems in practical use, which limits its further promotion in modern agricultural production. Utility Model Content

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the directional descriptions, such as "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "point," "inner," "outer," "axial," "radial," "circumferential," and "around," are based on the directional or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, sidewall refers to the left sidewall and / or the right sidewall.

[0036] In the description of this utility model, "multiple" means two or more; "greater than," "less than," "exceeding," etc., are understood to exclude the number itself; and "above," "below," "within," etc., are understood to include the number itself. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0037] In the description of this utility model, it should be understood that "A is set on B" or "A is set on B" describes the connection or positional relationship between A and B, and does not mean that A is necessarily above B.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, movable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. "Bolt connection" and "screw connection" can be used interchangeably. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood in conjunction with the specific circumstances. It should be understood that multiple similar features in this utility model are only distinguished by different prefixes. Therefore, in this utility model, the feature names without distinguishing prefixes (or feature names with partial prefixes) are used to represent the combination of similar features of this type. For example, "filter protrusion" is used to represent the first filter protrusion 210 and the second filter protrusion 220.

[0039] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the drip irrigation strip structure 100 is used to be loaded inside the drip irrigation tape 500, the drip irrigation tape 500 is used to circulate water resources 600, and the drip irrigation strip structure includes a strip body 110. The strip body 110 is provided with an inlet area 111, a flow stabilizing area 112 and an outlet area 113 in sequence along the water flow direction. The inlet area 111 is connected to the flow stabilizing area 112, and the flow stabilizing area 112 is connected to the outlet area 113. The strip body 110 is used to be loaded inside the drip irrigation tape 500. The inlet area 111 is provided with a filter structure 200. The flow stabilizing area 112 is provided with a flow stabilizing structure 300.

[0040] The drip irrigation strip structure 100 is installed inside the drip irrigation tape 500. Affected by gravity or the contraction elasticity of the drip irrigation tape itself (when the drip irrigation tape is stretched by the drip irrigation strip structure 100), at least one side of the strip body 110 will be attached to the inner wall of the drip irrigation tape. The water resources 600 in the drip irrigation tape will circulate in the space between the strip body 110 and the inner wall of the drip irrigation tape. Therefore, by setting some additional structures on the strip body 110 (i.e., the inlet area 111, the steady flow area 112, and the outlet area 113), it is possible to influence the water resources 600 circulating in the drip irrigation tape. The inlet zone 111 is equipped with a filter structure 200, which filters the water 600 flowing within the drip irrigation tape 500. The filtered water 600 flows to the flow stabilization zone 112, which is equipped with a flow stabilization structure 300 to stabilize the flow of water 600. Finally, the water 600 flows to the outlet zone 113, which is beneficial for subsequent drip irrigation. It should be understood that the filter structure 200 can take many forms, such as using a vertical filter screen or directly covering the inlet zone 111 with a mesh cover structure; it can also be equipped with multiple filter protrusions, with a limited gap between adjacent filter protrusions to intercept larger impurities 700; it can also be equipped with filter grooves, where larger impurities are trapped or even completely settled when the water flow rate is slow or the flow time is long; or a combination of the above-mentioned structures can be used to create the filter structure 200. The flow stabilizing structure 300 can take many forms, such as setting a water-blocking wall 310 and an oblique rack 320, or setting a pressure compensation waterway.

[0041] It should be understood that the shape of the sticker body 110 is not limited, and it is commonly plate-shaped or block-shaped (square, semi-cylindrical, etc.). In this embodiment, the sticker body 110 is a long plate-shaped strip. It is important to understand that the "water flow direction" refers to the main flow direction of the water resources 600 circulating in the space between the main body 110 of the strip and the inner wall of the drip irrigation tape. It is also important to understand that, due to the natural properties of the water resources 600, the flow directions of each stream of water resources 600 may differ. However, due to limitations imposed by spatial shape, gravity, and flow inertia, at a given location, the flow direction of most of the water resources 600 is approximately the same, which is the "main flow direction" described in this invention. Furthermore, it is important to understand that the "water flow direction" described in this invention is fixed at a given location, but it may change with the location; different flow directions may be different. Specifically, in this embodiment, the inlet zone 111, the stabilizing zone 112, and the outlet zone 113 are connected front to back, and the main body 110 is elongated, so the water flow direction is roughly fixed as a front-to-back flow. In other embodiments, such as when the inlet zone 111, the stabilizing zone 112, and the outlet zone 113 are connected in an S-shape, the overall water flow direction is also roughly S-shaped. It is important to understand that water resources refer to resources with a high water content, including tap water, natural water resources, fertilizers, pesticides, and other water-containing resources.

[0042] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the filter structure 200 is a first filter protrusion 210, and multiple first filter protrusions 210 are provided on both sides of the water inlet area 111 along the water flow direction.

[0043] Multiple filter protrusions are provided, and adjacent filter protrusions can easily form an interception structure, preventing larger impurities 700 from entering the deeper area of ​​the inlet zone 111 through the limited gap between the two filter protrusions. It should be understood that the specific shape and structure of the filter protrusions are not limited and can be set according to actual conditions; for example, they can be set as elliptical cylinders, or as cylinders, cubes, cuboids, hemispheres, or combinations of various shapes. It should be understood that "both sides of the water flow direction" refers to the left and right sides, defined by the direction perpendicular to the water flow, with the center of this area (inlet zone 111, steady flow zone 112, outlet zone 113) as the reference point.

[0044] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the first filter protrusion 210 is an elliptical cylindrical protrusion, which is obliquely arranged; along the water flow direction, the obliquely arranged elliptical cylindrical protrusion gets closer and closer to the middle of the water inlet area 111.

[0045] The elliptical cylindrical protrusions are arranged obliquely in this embodiment. When the water flow on both sides of the strip body 110 impacts the sidewall of the elliptical cylindrical protrusions, the water flow is more likely to enter the central area of ​​the inlet zone 111 along the sidewall, and finally enter the stabilizing zone 112 and the outlet zone 113, thus playing a role in water collection. The elliptical cylindrical shape has two advantages: firstly, the rounded ends of the elliptical cylinder reduce the obstruction of the water flow, enhancing the water collection effect; secondly, the longer body length of the elliptical cylinder makes it easier to form a larger interception area with other elliptical cylinders, thus strengthening the blocking effect on impurities 700. The description of the oblique arrangement of the elliptical cylindrical protrusions as "along the water flow direction, the obliquely arranged elliptical cylindrical protrusions get closer and closer to the center of the inlet zone 111" indicates the specific oblique direction of the elliptical cylindrical protrusions. In this embodiment, an elliptical cylindrical protrusion, viewed from front to back, will increasingly deviate towards the center of the inlet zone 111; the subsequent oblique toothed rack 320 follows the same principle.

[0046] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the gap between any two adjacent first filter protrusions 210 on any side is less than 0.2 mm.

[0047] The gap between two adjacent filter protrusions (or the minimum interval between two adjacent filter protrusions) is less than 0.2 mm, which can basically intercept impurities below 80 mesh (the smaller the mesh number, the larger the particle size of impurities 700), which basically meets the actual needs of agricultural drip irrigation. While setting it smaller can block smaller impurities 700, it is also more prone to clogging and has a higher manufacturing cost.

[0048] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a second filter protrusion 220 is provided in the middle of the water inlet area 111.

[0049] The addition of a second filter protrusion 220 further increases the filtration capacity. It should be understood that the shape of the second filter protrusion 220 can also be similar to that of the first filter protrusion 210 described above. It should also be understood that the gap between the second filter protrusion 220 and the first filter protrusion 210 can be specifically set, for example, to be less than 0.2 mm.

[0050] It is important to understand that the first filter protrusion 210 and the second filter protrusion 220 also serve a supporting function, preventing the water inlet area 111 on the main body 110 from completely adhering to the inner wall of the drip irrigation tape. This creates a certain flow space for water resources 600 between the main body 110 and the inner wall of the drip irrigation tape. The subsequent water-blocking wall 310, oblique toothed rack 320, sealing wall 410, bottom sealing wall 420, and support protrusion 440 also serve the same purpose. In particular, the second filter protrusion 220 prevents the inner wall of the drip irrigation tape from collapsing and adhering to the middle of the water inlet area 111, thus creating a complete water inlet channel. This facilitates the flow of water resources 600 filtered by the first filter protrusion 210 into this water inlet channel.

[0051] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the flow stabilizing structure 300 includes a water-blocking wall 310 and an oblique rack 320. A water-blocking wall 310 is provided on both sides of the flow stabilizing zone 112 along the water flow direction, and multiple oblique racks 320 are provided on the inner side of the two water-blocking walls 310. Along the water flow direction, the oblique racks 320 get closer and closer to the middle of the flow stabilizing zone 112.

[0052] Two water-retaining walls 310 are installed to delineate a relatively independent area—the steady-flow channel—within the steady-flow zone 112. This serves two purposes: firstly, it prevents water from flowing in from the outside into the steady-flow channel; secondly, it prevents water resources 600 from flowing out of the steady-flow channel. The inner sides of the two water-retaining walls 310 are intersected with oblique toothed racks 320, further optimizing the distribution and flow of water. When water flows through the steady-flow channel, it is divided into multiple small water flow branches by the oblique toothed racks 320. These branched water flows collide and merge with each other, achieving a more uniform water flow distribution. For the entire drip irrigation system, this ensures that each dripper receives a more uniform amount of water. The oblique toothed racks 320 are elongated structures, and multiple oblique toothed racks 320 are installed on one water-retaining wall 310, making the overall structure resemble a comb.

[0053] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a closed wall 410 is provided on both sides of the water outlet area 113 along the water flow direction, a bottom sealing wall 420 is provided at the end of the water outlet area 113 away from the steady flow area 112, one end of the bottom sealing wall 420 is connected to a closed wall 410, the other end of the bottom sealing wall 420 is connected to another closed wall 410, and a water outlet 430 is provided in the middle of the water outlet area 113.

[0054] The sealing wall 410 and the bottom sealing wall 420 enclose an independent water outlet area 113, providing a relatively stable environment unaffected by external factors. An outlet 430 is provided within this water outlet area 113 for stable water flow. It should be understood that in this embodiment, one end of a sealing wall 410 is connected to a bottom sealing wall 420 on the same side, and the other end of the sealing wall 410 is connected to one end of a water-retaining wall 310. Similarly, one end of another sealing wall 410 is connected to another bottom sealing wall 420, and the other end of the sealing wall 410 is connected to the other end of the water-retaining wall 310, thus better enclosing the water outlet area 113 and completely connecting the stable flow channel and the water outlet area 113. It should also be understood that in the drip irrigation system, corresponding areas on the drip irrigation tape 500 are provided with openings (or drip inlets) so that water resources 600 flowing from the outlet 430 can drip-irrigate the corresponding areas. It should be understood that the outlet 430 can be of various shapes, such as the elongated shape in this embodiment, extending in the front-to-back direction, conforming to the shape of the water outlet area 113, with a larger water outlet range, less affected by other factors, and more stable water outlet.

[0055] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the water outlet area 113 is provided with a plurality of support protrusions 440.

[0056] Because the outlet area 113 is relatively open, the inner wall of the drip irrigation tape may collapse and adhere to the middle of the outlet area 113, which could block the outlet 430 and be detrimental to the stability of the entire outlet area 113. The second filter protrusion 220, on the other hand, can support a complete outlet area 113, facilitating stable water flow in the outlet area 113.

[0057] Reference Figure 1 and Figure 2 According to the present utility model, the drip irrigation strip includes the aforementioned drip irrigation strip structure 100. Multiple drip irrigation strip structures 100 are provided, and any one drip irrigation strip structure 100 is connected to at least another drip irrigation strip structure 100.

[0058] Multiple drip irrigation strip structures 100 are connected together, making procurement, transportation, storage, and use more convenient. It's important to understand that the connection of multiple drip irrigation strip structures 100 can be as follows: each drip irrigation strip structure 100 can be connected end-to-end to form a long strip, facilitating its use with long strip drip irrigation tape 500; it can also be cut to size as needed. The connection of multiple drip irrigation strip structures 100 can also be as follows: they can be connected side-by-side, or in addition to the above end-to-end connection, further facilitating production, procurement, transportation, and storage. The connection of multiple drip irrigation strip structures 100 can also be for other specific purposes. For example, every two drip irrigation strip structures 100 can be combined into a unit. Within this unit, the two drip irrigation strip structures 100 can be connected end-to-end, double-ended (for planting units with two types of plants grown together using methods such as companion, intercropping, or parasitism, a double-ended unit facilitates simultaneous drip irrigation of two plants), double-ended, side-to-side, or top-to-bottom, etc., while each unit can be connected to each other in other ways.

[0059] Reference Figure 1 and Figure 2 The drip irrigation system according to the present utility model includes the aforementioned drip irrigation strip structure 100 and drip irrigation tape 500, wherein the drip irrigation strip structure 100 is disposed within the drip irrigation tape 500.

[0060] The drip irrigation tape 500 comes pre-installed with the drip irrigation strip structure 100, making it convenient to use directly after purchase without the need for additional installation of the drip irrigation strip structure 100 later.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
