Description

Technical Field

[0001] This invention relates to the field of agricultural drip irrigation technology, and in particular to a compensating drip tape pipe. Background Technology

[0002] In agricultural planting, providing water resources to crops is the foundation for ensuring their normal growth. Water resources are usually provided to crops through irrigation, which is mainly divided into two types: sprinkler irrigation and drip irrigation. Sprinkler irrigation mainly involves spraying, and the sprayed area often covers the planting area of ​​the crops. However, crops are planted at intervals, and some water resources will be sprayed into areas that do not need irrigation during sprinkler irrigation, resulting in water waste. For arid and water-scarce areas, sprinkler irrigation cannot be effectively implemented. Drip irrigation, on the other hand, is an effective water-saving irrigation method that can be used for irrigating fruit trees, vegetables, cash crops, and greenhouses. It can also be used for irrigating field crops in arid and water-scarce areas.

[0003] Drip irrigation is mainly achieved through drip tape, which is a tubular structure with holes for dripping. These holes deliver water to the roots of crops for localized irrigation. However, drip tape currently suffers from a common problem: dripping is significantly affected by changes in water pressure. The dripping rate varies with water pressure, resulting in low dripping stability and consequently affecting irrigation effectiveness.

[0004] Therefore, there is an urgent need for a compensating drip tape pipe with high drip stability and good irrigation effect. Summary of the Invention

[0005] The purpose of this invention is to provide a compensating drip tape to solve the problems existing in the prior art. It utilizes the turbulent effect of the turbulent pattern to compensate for water pressure, improve drip stability, and thus improve irrigation effect.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a compensating drip tape pipe, including a water supply channel and a turbulent flow channel. The turbulent flow channel is connected to the water supply channel through an inlet channel. The turbulent flow channel is provided with multiple outlet channels for dripping. The inlet channel and the outlet channel are staggered. The inner wall of the pipe corresponding to the inlet channel and the outlet channel is provided with a turbulent flow pattern.

[0007] Preferably, the compensating drip tape includes a first tape layer, a second tape layer, and a third tape layer. The side edges of the first tape layer and the second tape layer are connected to form the water supply channel, and the side edges of the second tape layer and the third tape layer are connected to form the turbulence channel.

[0008] Preferably, the turbulent pattern is disposed on the end face of the second strip layer near the third strip layer.

[0009] Preferably, the first strip layer, the second strip layer, and the third strip layer are integrally formed.

[0010] Preferably, the first strip layer, the second strip layer, and the third strip layer are separately configured.

[0011] Preferably, the first, second, and third strip layers are made of PE, PP, or a composite material consisting of two layers of LLDPE / POE blend sandwiching a layer of HDPE.

[0012] Preferably, the turbulent pattern is a plurality of uniformly distributed arc-shaped grooves.

[0013] Preferably, multiple water inlet channels are provided, and both the water inlet channel and the water outlet channel are strip-shaped slits.

[0014] Preferably, the water inlet channel and the water outlet channel are parallel.

[0015] Preferably, the water inlet channel and the water outlet channel are located in the same plane.

[0016] The present invention achieves the following main technical effects compared to the prior art: Water flows from the water supply channel through the inlet channel into the turbulent channel. After being subjected to the turbulent flow pattern, it is discharged from the outlet channel to complete the drip infiltration. The disorder and energy consumption of the turbulent flow caused by the turbulent flow pattern can reduce the amplitude of water pressure changes and achieve pressure compensation, thereby improving the stability of drip infiltration and thus improving the irrigation effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a compensating drip tape to solve the problems existing in the prior art. It utilizes the turbulent effect of the turbulent pattern to compensate for water pressure, improve drip stability, and thus improve irrigation effect.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 As shown, a compensating drip irrigation tape pipe is provided, including a water supply channel 4 and a turbulent flow channel 5. The turbulent flow channel 5 is connected to the water supply channel 4 through an inlet channel 6. Multiple outlet channels 7 are provided on the turbulent flow channel 5. The outlet channels 7 are channels used for drip irrigation. The inlet channel 6 and the outlet channels 7 are staggered. Turbulent flow patterns 8 are provided on the inner wall of the pipe between the inlet channel 6 and the outlet channels 7, so that the water flowing from the inlet channel 6 to the outlet channel 7 must pass through the turbulent flow patterns 8. After being subjected to the turbulent flow pattern 8, the water flows out from the outlet channel 7 to complete the drip irrigation. The disorder and energy consumption of the turbulence caused by the turbulent flow pattern 8 can reduce the amplitude of water pressure changes, realize the pressure compensation function, thereby improve the drip irrigation stability and improve the irrigation effect.

[0023] In this embodiment, the compensating drip tape includes a first tape layer 1, a second tape layer 2, and a third tape layer 3. The side edges of the first tape layer 1 and the second tape layer 2 are connected to form a water supply channel 4, and the side edges of the second tape layer 2 and the third tape layer 3 are connected to form a turbulent flow channel 5. The side edges of the first tape layer 1 and the second tape layer 2, as well as the second tape layer 2 and the third tape layer 3, are connected by heat sealing. In another embodiment, two pipe bodies can be used as the water supply channel 4 and the turbulent flow channel 5, respectively. The two pipe bodies are glued together, and a water inlet channel 6 is opened on the connection surface.

[0024] In this embodiment, the turbulent pattern 8 is set on the end face of the second layer 2 near the third layer 3, so that the turbulent pattern 8 does not need to be processed on the third layer 3 as well, thus reducing the number of processes and lowering the cost.

[0025] In this embodiment, the first belt layer 1, the second belt layer 2, and the third belt layer 3 are integrally formed by folding a complete belt layer twice, and the folding line is parallel to the length direction of the belt layer.

[0026] In another embodiment, the first strip layer 1, the second strip layer 2, and the third strip layer 3 can be separately configured.

[0027] The first layer 1, the second layer 2, and the third layer 3 are made of PE or PP, or a composite material consisting of two layers of LLDPE / POE blend sandwiching a layer of HDPE. The two layers of LLDPE / POE blend and the middle HDPE layer form an ABA material structure, wherein the turbulent channel pattern pressed by the ABA material structure is elastic and beneficial for water pressure compensation. In other embodiments, other materials suitable for pipe manufacturing can also be used to make the first layer 1, the second layer 2, and the third layer 3.

[0028] In this embodiment, the turbulent pattern 8 is a plurality of uniformly distributed arc-shaped grooves. In other embodiments, the turbulent pattern 8 can be a plurality of raised strip structures, arc-shaped structures or block structures, or a plurality of groove structures of other shapes.

[0029] In this embodiment, multiple water inlet channels 6 are provided. Both the water inlet channel 6 and the water outlet channel 7 are strip-shaped slits. The strip-shaped slits can be formed by cutting with a tool or by wire cutting.

[0030] The water inlet channel 6 and the water outlet channel 7 are parallel to avoid frequent reversal of the cutting tool during processing, thus improving cutting efficiency.

[0031] To further improve cutting efficiency, the water inlet channel 6 and the water outlet channel 7 are located in the same plane.

[0032] The water flow rate of this device can be adjusted by adjusting the depth, length, width, and density of the turbulent pattern 8.

[0033] This device can be laid on the ground surface, can be shallowly buried, and has strong anti-clogging performance.

[0034] In actual use, the water pump supplies water to the water supply channel 4. The water in the water supply channel 4 enters the turbulent channel 5 from the inlet channel 6. Due to the misalignment of the inlet channel 6 and the outlet channel 7, the water flowing out of the inlet channel 6 will inevitably pass through the turbulent pattern 8 to generate turbulence, thereby achieving pressure compensation. The water in the turbulent channel 5 will eventually drip out from the outlet channel 7.

[0035] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0036] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
