Description

Technical Field

[0001] The invention relates to the technical field of agricultural drip irrigation, in particular to a compensating drip irrigation belt pipe. Background Art

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

[0003] Drip irrigation is mainly achieved through drip irrigation pipes. The drip irrigation pipe body is a tubular structure with holes opened on it as drip holes, which are used to supply the water resources transported in the drip irrigation pipes to the roots of crops to achieve local irrigation. However, the drip irrigation pipes currently generally have the problem that the drip infiltration is greatly affected by changes in water flow pressure. The drip infiltration speed will change with the change in water pressure, and the drip infiltration stability is relatively low, which in turn affects the irrigation effect.

[0004] Therefore, people are in urgent need of a compensating drip infiltration belt pipe with high drip infiltration stability and good irrigation effect. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a compensating drip infiltration belt pipe to solve the problems existing in the prior art, utilize the turbulent effect of the turbulent pattern to compensate for the water pressure, improve the drip infiltration stability, and further improve the irrigation effect.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to Figure 1 , Figure 2 As shown, a compensating drip infiltration belt pipe is provided, including a water supply channel 4 and a turbulent flow channel 5. The turbulent flow channel 5 is connected with the water supply channel 4 through a water inlet channel 6. A plurality of water outlet channels 7 are arranged on the turbulent flow channel 5. The water outlet channels 7 are channels for drip infiltration. The water inlet channel 6 and the water outlet channel 7 are staggered. A turbulent flow pattern 8 is arranged on the inner wall of the pipeline between the water inlet channel 6 and the water outlet channel 7 of the turbulent flow channel 5, so that the water flowing from the water inlet channel 6 to the water outlet channel 7 must pass through the turbulent flow pattern 8. After the water flow is affected by the turbulent flow of the turbulent flow pattern 8, it is discharged from the water outlet channel 7 to complete the drip infiltration. The disorder and energy consumption of the turbulence caused by the turbulent flow pattern 8 can reduce the amplitude of the water pressure change, realize the effect of pressure compensation, thereby improving the stability of drip infiltration, and further improving the irrigation effect.

[0023] In this embodiment, the compensating drip infiltration belt pipe includes a first belt layer 1, a second belt layer 2 and a third belt layer 3. The side edges of the first belt layer 1 and the second belt layer 2 are connected to form a water supply channel 4, and the side edges of the second belt layer 2 and the third belt layer 3 are connected to form a turbulent flow channel 5. The side edges of the first belt layer 1 and the second belt layer 2 and the second belt layer 2 and the third belt layer 3 are connected by heat sealing. In another embodiment, two pipe bodies can also 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 connecting surface.

[0024] In this embodiment, the turbulent pattern 8 is arranged on the end surface of the second belt layer 2 close to the third belt layer 3, and the turbulent pattern 8 does not need to be processed on the third belt layer 3, thereby reducing the number of steps 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 arranged, and the three belt layers are 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 belt layer 1, the second belt layer 2 and the third belt layer 3 can be provided separately.

[0027] The material of the first belt layer 1, the second belt layer 2 and the third belt layer 3 is PE or PP, or a composite material of two layers of LLDPE / POE blend sandwiched with a layer of HDPE is selected, and the two layers of LLDPE / POE blend and the middle HDPE layer form an ABA material structure, wherein the turbulent flow channel pattern pressed by the ABA material structure has elasticity and is conducive to water pressure compensation; in other embodiments, other materials suitable for the production of the pipe body can also be selected to make the first belt layer 1, the second belt layer 2 and the third belt layer 3.

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

[0029] In this embodiment, a plurality of water inlet channels 6 are provided, and both the water inlet channels 6 and the water outlet channels 7 are strip-shaped seams, which can be formed by tool cutting or wire cutting.

[0030] The water inlet channel 6 and the water outlet channel 7 are parallel to each other, so that frequent reversal of the slitting tool is avoided when processing the water inlet channel 6 and the water outlet channel 7, thereby improving the slitting efficiency.

[0031] In order to further improve the 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 the device can be adjusted by adjusting the depth, length, width and pattern density of the turbulent pattern 8.

[0033] The device can be laid on the land surface and can be used shallowly, and has strong anti-clogging performance.

[0034] During actual use, the water pump supplies water to the water supply channel 4, and the water in the water supply channel 4 enters the turbulent channel 5 from the water inlet channel 6. Since the water inlet channel 6 and the water outlet channel 7 are staggered, the water flowing out of the water 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 water outlet channel 7.

[0035] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0036] It should be noted that it is obvious to those skilled in the art 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 features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
