Belt member for drip irrigation belt, and drip irrigation belt

Abstract

A belt member for a drip irrigation belt. Each drip irrigation unit comprises two water intake sections (1, 5) and two pressure reduction sections (2, 4), wherein one water intake section and one pressure reduction section are provided at two ends of a water output section (3), respectively. Even though flow channels of the water intake section and the pressure reduction section at one end of the water output section of the belt member are blocked, water can also flow into the water output section from the water intake section and the pressure reduction section at the other end of the water output section, thereby achieving stronger anti-blocking performance, shorter water intake sections and pressure reduction sections designed on two sides, and a lower probability of blockage. A drip irrigation belt comprising the belt member is further comprised.

Description

Belt components for drip irrigation tape and drip irrigation tape Technical Field

[0001] This disclosure relates to the field of drip irrigation technology, and more specifically, to a tape component for drip irrigation tape and a drip irrigation tape. Background Technology

[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipeline system to deliver water directly to the field. The water is then dripped evenly and slowly into the soil near the crop root zone through emitters, orifices, or drip tapes installed on the capillary tubes. This keeps the soil in the most developed root zone at a suitable level of moisture, ensuring that the soil's water, fertilizer, air, heat, and microbial activity are always in good condition, creating favorable conditions for high and stable crop yields.

[0003] As a type of drip irrigation tape, strip drip irrigation tape features integral hot-press molding, good adhesion, and high manufacturing precision. The drip unit, the core unit of strip drip irrigation tape, typically includes an inlet section, a pressure-reducing section, and an outlet section. During use, water from the drip irrigation tape hose enters through the inlet section, is pressure-reduced in the pressure-reducing section, and then flows out through the outlet section; this is a single-sided inlet design.

[0004] However, existing drip irrigation strips use a single-sided water inlet design. If the only inlet or the flow channel in the pressure-reducing section of the strip becomes blocked, water cannot flow to the outlet section, rendering the corresponding drip irrigation unit unusable. Therefore, how to further improve the anti-clogging performance of single-sided water inlet drip irrigation units has become a problem. Summary of the Invention

[0007] Each of the drip irrigation units includes a drip irrigation unit water supply channel formed by the sequential fluid connection of a first water inlet section, a first pressure reducing section, a water outlet section, a second pressure reducing section, and a second water inlet section;

[0008] Water from the main water supply channel enters the drip irrigation unit's water supply channel through the first water inlet section and the second water inlet section, and flows into the outlet section after being depressurized through the first pressure reducing section and the second pressure reducing section.

[0009] Optionally, the first water inlet section and the second water inlet section each include inlet prefabricated components spaced apart, the inlet prefabricated components connecting the bottom wall of the belt member to the inner wall of the hose;

[0010] Water from the main water supply channel enters the drip irrigation unit's water supply channel through the gaps between the spaced inlet prefabricated components.

[0011] Optionally, the inlet prefabricated component is one or a combination of elliptical, rectangular, circular, or triangular components; the inlet prefabricated component is in two rows, and the two rows of inlet prefabricated components form part of the flow path of the drip irrigation unit water supply channel.

[0012] Optionally, the inlet prefabricated component is an elliptical or rectangular component, with the inlet prefabricated component of the first water inlet section being disposed laterally toward the first pressure-reducing section, and the inlet prefabricated component of the second water inlet section being disposed laterally toward the second pressure-reducing section.

[0013] Optionally, the first decompression section and the second decompression section each include a plurality of decompression preforms, and the configuration of the decompression preforms includes at least one of a triangular configuration, an arc-tooth configuration, and a trapezoidal configuration.

[0014] Optionally, the first depressurization section and the second depressurization section may use different depressurization preforms.

[0015] Optionally, the pressure-reducing preforms are arranged in two rows, with the two rows of pressure-reducing preforms staggered and spaced apart to form a labyrinth flow channel.

[0016] Optionally, the belt member includes two side walls, which are respectively connected to the bottom wall of the belt member and the inner wall of the hose;

[0017] The two rows of pressure-reducing prefabricated components are respectively disposed on the two side walls, and the connection between the pressure-reducing prefabricated components and the side walls is arc-shaped.

[0018] Optionally, the length of one of the drip irrigation units is 80-160 mm, the lengths of the first water inlet section and the second water inlet section are 8-16 mm, the lengths of the first pressure reducing section and the second pressure reducing section are 12-24 mm, and the length of the water outlet section is 40-80 mm.

[0019] Optionally, the length of one of the drip irrigation units is 100mm, the lengths of the first water inlet section and the second water inlet section are 10mm, the lengths of the first pressure reducing section and the second pressure reducing section are 15mm, and the length of the water outlet section is 50mm.

[0020] In a second aspect, a drip irrigation tape is provided, comprising: a flexible tube, and a tape component as described in any one of claims 1-10;

[0021] The belt component engages with the inner wall of the hose to form several drip irrigation units.

[0022] This disclosure provides a tape component for drip irrigation tape, comprising: a tape component for engaging with the inner wall of the flexible tube of the drip irrigation tape to form a plurality of drip irrigation units; the inner wall of the flexible tube of the drip irrigation tape for forming a main water supply channel; each drip irrigation unit includes a drip irrigation unit water supply channel formed by sequentially fluidly connecting a first water inlet section, a first pressure reducing section, an outlet section, a second pressure reducing section, and a second water inlet section; water from the main water supply channel enters the drip irrigation unit water supply channel through the first water inlet section and the second water inlet section respectively, and flows into the outlet section after being pressure reduced by the first pressure reducing section and the second pressure reducing section respectively. In other words, the drip irrigation unit includes two inlet sections and two pressure-reducing sections. The outlet section has one inlet section and one pressure-reducing section at each end. This ensures that even if the flow path of one inlet or pressure-reducing section at the outlet end becomes blocked, water can still flow into the outlet section from the other inlet or pressure-reducing section. This results in stronger anti-clogging performance and avoids the problem that if only one inlet or pressure-reducing section of a single-sided inlet drip irrigation tape becomes blocked, the corresponding outlet section will also become unusable. Furthermore, compared to a single-sided inlet design, with a fixed drip irrigation unit length and a fixed overall length of the inlet and pressure-reducing sections, the lengths of the inlet and pressure-reducing sections in a double-sided design are shorter, reducing the probability of clogging.

[0038] The deficiencies in the existing technology are all results of the inventors' practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as contributions made by the inventors to this disclosure.

[0039] This disclosure provides a belt component for drip irrigation tape, as shown in Figures 1-3, including: the belt component for cooperating with the inner wall of the drip irrigation tape hose to form a plurality of drip irrigation units; the inner wall of the drip irrigation tape hose for forming a main water supply channel;

[0040] Each of the drip irrigation units includes a drip irrigation unit water supply channel formed by the sequential fluid connection of a first water inlet section 1, a first pressure reducing section 2, a water outlet section 3, a second pressure reducing section 4, and a second water inlet section 5;

[0041] Water from the main water supply channel enters the drip irrigation unit water supply channel through the first water inlet section 1 and the second water inlet section 5, and flows into the outlet section 3 after being depressurized through the first pressure reducing section 2 and the second pressure reducing section 4.

[0042] Adjacent drip irrigation units can share the same first or second water inlet section, as shown in Figure 2. Water inlet section 1 can serve as the first water inlet section of this drip irrigation unit, and can also serve as the second water inlet section of an adjacent drip irrigation unit. Adjacent drip irrigation units can also have their own first or second water inlet section, as shown in Figure 3. Water inlet section 6 is the second water inlet section of an adjacent drip irrigation unit, and water inlet section 7 is the first water inlet section of an adjacent drip irrigation unit.

[0043] This disclosure provides a tape component for drip irrigation tape. The drip irrigation unit includes two inlet sections and two pressure-reducing sections. Each end of the outlet section has an inlet section and a pressure-reducing section. This ensures that even if the flow channels of one inlet or pressure-reducing section at one end of the outlet section become blocked, water can still flow into the outlet section from the other end. This results in stronger anti-clogging performance and avoids the problem that if only one inlet or pressure-reducing section of a single-sided inlet drip irrigation tape becomes blocked, the corresponding outlet section will also become unusable. Furthermore, compared to a single-sided inlet design, with a fixed drip irrigation unit length and a fixed overall length of the inlet and pressure-reducing sections, the lengths of the inlet and pressure-reducing sections in a double-sided design are shorter, resulting in a lower probability of clogging.

[0044] This disclosure provides a possible implementation method. Specifically, the first water inlet section and the second water inlet section each include a plurality of spaced inlet prefabricated components 11. The inlet prefabricated components connect the bottom wall of the component (not shown in the figure) to the inner wall of the hose (not shown).

[0045] Water from the main water supply channel enters the drip irrigation unit water supply channel through the gaps 12 between the spaced inlet prefabricated components (as shown in Figures 4 and 5).

[0046] Specifically, the inlet section can be equipped with multiple inlet prefabricated components, and the spacing between the inlet prefabricated components can be different or the same. Specifically, the spacing between the inlet prefabricated components can be reduced sequentially from the middle of the inlet section towards the depressurization section. That is to say, the closer to the depressurization section, the smaller the gap between the inlet prefabricated components, thereby preventing larger particles (such as sand) in the water from entering the inlet section channel and clogging the depressurization section channel, and further improving the anti-clogging performance.

[0047] Specifically, the first and second water inlet sections may further include fixed prefabricated components 9, which may be circular, elliptical, rectangular, triangular, or other configurations capable of achieving the functions of this application. Specifically, the fixed prefabricated component 9 connects the bottom wall of the connecting strip component and the inner wall of the hose. Furthermore, the water outlet section may also include corresponding fixed prefabricated components.

[0048] This embodiment solves the specific design problem of the water inlet section. In addition, the inlet prefabricated component of the water inlet section has a certain filtering function, which plays a certain role in preventing blockage.

[0049] This disclosure provides a possible implementation method. Specifically, the inlet prefabricated component is one or a combination of elliptical, rectangular, circular, or triangular components; the inlet prefabricated component is in two rows, and the two rows of inlet prefabricated components form part of the flow path of the drip irrigation unit water supply channel.

[0050] Specifically, the inlet prefabricated component is an elliptical (as shown in Figure 4, 11), a rectangular (as shown in Figure 5, 11), a circular or triangular component, or other configurations that can achieve the function of this patent; specifically, there can be multiple inlet prefabricated components in the inlet section, and these multiple inlet prefabricated components can adopt the same configuration, such as elliptical or rectangular, or they can adopt different configurations, such as partially elliptical and partially rectangular.

[0051] Specifically, as shown in Figures 1-5, the inlet prefabricated components can be arranged in two rows. Since the inlet prefabricated components have a certain height, the inlet prefabricated components connect the bottom wall of the belt component and the inner wall of the hose. The cooperation between the two rows of inlet prefabricated components and the bottom wall of the belt component and the inner wall of the hose can form a flow channel in the inlet section. Water can enter from the gaps in the inlet prefabricated components and enter the decompression section through the flow channel formed by the two rows of inlet prefabricated components.

[0052] The embodiments disclosed herein solve the specific design problem of the entrance prefabricated component.

[0053] This disclosure provides a possible implementation method. Specifically, the inlet prefabricated component is an elliptical or rectangular component. The inlet prefabricated component of the first water inlet section is disposed laterally toward the first pressure-reducing section, and the inlet prefabricated component of the second water inlet section is disposed laterally toward the second pressure-reducing section.

[0054] Specifically, the inlet prefabricated component can be an elliptical shape as shown in Figures 1 and 4, or a rectangular inlet prefabricated component as shown in Figures 2, 3, and 5. As shown in Figure 5, the inlet prefabricated component of the first water inlet section of one drip irrigation unit is positioned laterally towards the first pressure-reducing section, and the inlet prefabricated component of the second water inlet section of another drip irrigation unit is positioned laterally towards the second pressure-reducing section.

[0055] In this embodiment, the inlet prefabricated components of the first and second inlet sections are laterally positioned towards the corresponding pressure-reducing sections. This lateral positioning has a certain guiding effect, allowing water to smoothly pass through the gaps in the inlet prefabricated components of the inlet sections and enter the inlet section flow channel, flowing into the corresponding pressure-reducing sections.

[0056] This disclosure provides a possible implementation method. Specifically, the first decompression section and the second decompression section each include a plurality of decompression preforms 21, and the configuration of the decompression preforms includes at least one of a triangular configuration, an arc-tooth configuration, and a trapezoidal configuration.

[0057] Specifically, as shown in Figure 4, an arc-tooth configuration is shown; as shown in the right part of Figure 5 and the lower left part of Figure 5, a triangular configuration is shown; and as shown in the upper left part of Figure 5, a trapezoidal pressure-reducing preform is shown. The pressure-reducing preform can also be other configurations that can realize the function of this application.

[0058] Specifically, as shown in Figures 1-5, the pressure-reducing preforms are arranged in two rows, with each row of pressure-reducing preforms spaced apart to form a labyrinth flow channel.

[0059] Specifically, the prefabricated pressure-reducing components in each row can be placed adjacent to each other without any spacing, as shown in Figures 6 and 7.

[0060] Specifically, the belt member includes two side walls, which are respectively connected to the bottom wall (not shown) of the belt member and the inner wall (not shown) of the hose;

[0061] The two rows of pressure-reducing prefabricated components are respectively disposed on the two side walls. The connection between the pressure-reducing prefabricated components and the side walls is arc-shaped (as shown in Figures 7 and 8). The arc-shaped design can further improve the anti-clogging performance of the flow channel.

[0062] Specifically, the first and second pressure-reducing sections employ different pressure-reducing prefabricated components. Since different pressure-reducing prefabricated component configurations may be suitable for different water environments, for example, configuration 1 has better anti-clogging performance in water quality environment 1, while configuration 2 has better anti-clogging performance in water quality environment 2. That is to say, even if configuration 2, which has weaker anti-clogging performance in water quality environment 1, becomes clogged, the pressure-reducing section using configuration 1 can still be used, thus enabling the drip irrigation tape to maintain a certain level of anti-clogging performance in various water quality environments.

[0063] This disclosure provides a possible implementation method. Specifically, the belt component includes two side walls that extend from the decompression section to the water outlet section. In the water outlet section, the two side walls form a cavity, and the water entering the water outlet section can flow out through several openings provided on the hose to achieve the purpose of drip irrigation.

[0064] Specifically, the outlet section can also be equipped with several prefabricated fasteners, which can connect the bottom wall of the component and the inner wall of the hose.

[0065] The present invention addresses the design problem of the outlet section.

[0066] This disclosure provides a possible implementation method. Specifically, the length of one of the drip irrigation units is 80-160 mm, the lengths of the first water inlet section and the second water inlet section are 8-16 mm, the lengths of the first pressure reducing section and the second pressure reducing section are 12-24 mm, and the length of the water outlet section is 40-80 mm.

[0067] Specifically, the length of one of the drip irrigation units is 80, the lengths of the first water inlet section and the second water inlet section are 8, the lengths of the first pressure reducing section and the second pressure reducing section are 12, and the length of the water outlet section is 40.

[0068] Specifically, the length of one of the drip irrigation units is 160mm, the lengths of the first water inlet section and the second water inlet section are 16mm, the lengths of the first pressure reducing section and the second pressure reducing section are 24mm, and the length of the water outlet section is 80mm.

[0069] Specifically, the length of one of the drip irrigation units is 100mm, the lengths of the first water inlet section and the second water inlet section are 10mm, the lengths of the first pressure reducing section and the second pressure reducing section are 15mm, and the length of the water outlet section is 50mm.

[0070] Specifically, the length of the drip irrigation unit can also be any other length that can achieve the corresponding function.

[0071] For example, the length of one of the drip irrigation units is 100mm. If the length of the water outlet section is 50mm, and a single-sided water inlet method is used, the length of the water inlet section is 20mm and the length of the pressure reducing section is 30mm. In contrast, a double-sided water inlet method has a length of 10mm for each water inlet section and a pressure reducing section of 15mm. That is to say, given a fixed length of the drip irrigation unit and the length of the outlet section, a double-sided water inlet method allows for a shorter length of the water inlet section and the pressure reducing section compared to a single-sided water inlet method, resulting in better anti-clogging performance.

[0072] In a second aspect, a drip irrigation tape is provided, comprising: a flexible tube, and a tape component as described in any embodiment of the first aspect;

[0073] The belt component engages with the inner wall of the hose to form several drip irrigation units.

[0074] Specifically, the tape components can be prefabricated and then heat-pressed with the drip tape hose to form a drip irrigation unit.

[0075] Specifically, the inner wall of the drip irrigation tape's hose is used to form a main water supply channel; each drip irrigation unit includes a drip irrigation unit water supply channel formed by sequentially fluidly connecting a first water inlet section, a first pressure reducing section, an outlet section, a second pressure reducing section, and a second water inlet section; water from the main water supply channel enters the drip irrigation unit water supply channel through the first water inlet section and the second water inlet section respectively, and flows into the outlet section after being pressure reduced by the first pressure reducing section and the second pressure reducing section respectively.

[0076] Specifically, the hose corresponding to the water outlet section can be equipped with several openings so that water can flow out from the openings of the hose.

[0077] This disclosure provides a tape component for drip irrigation tape, comprising: a tape component for engaging with the inner wall of the flexible tube of the drip irrigation tape to form a plurality of drip irrigation units; the inner wall of the flexible tube of the drip irrigation tape for forming a main water supply channel; each drip irrigation unit includes a drip irrigation unit water supply channel formed by sequentially fluidly connecting a first water inlet section, a first pressure reducing section, an outlet section, a second pressure reducing section, and a second water inlet section; water from the main water supply channel enters the drip irrigation unit water supply channel through the first water inlet section and the second water inlet section respectively, and flows into the outlet section after being pressure reduced by the first pressure reducing section and the second pressure reducing section respectively. In other words, the drip irrigation unit includes two inlet sections and two pressure-reducing sections. The outlet section has one inlet section and one pressure-reducing section at each end. This means that even if the flow channel of one end of the inlet section or pressure-reducing section is blocked, water can still flow into the outlet section from the other end. This results in stronger anti-clogging performance and avoids the problem that if the flow channel of only one inlet section or only one pressure-reducing section of the single-sided inlet drip irrigation tape is blocked, the corresponding outlet section will also become unusable.
