Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation equipment, and in particular to a semi-fixed drip irrigation tape. Background Technology

[0002] Drip irrigation is a method of watering crops by slowly and evenly dripping water and nutrients into the root zone of crops, using a pipeline system and emitters installed on capillary tubes. Drip tape, as an important component of drip irrigation systems, is widely used in agricultural production.

[0003] In modern agricultural irrigation operations, drip irrigation tape, as a key component of efficient water-saving irrigation systems, is widely used in various types of farmland. To ensure the stable operation of drip irrigation tape after it is laid in the farmland and to avoid problems such as displacement or tangling, U-shaped clips are often used to semi-fix the drip irrigation tape by inserting them into the soil.

[0004] However, existing U-shaped clips have a relatively simple design, limiting their function to semi-fixing drip irrigation tape. In practical applications, the drip holes on the drip irrigation tape are highly susceptible to external factors. For example, unintentional trampling by animals in farmland can directly damage the drip irrigation tape and cause physical damage to the drip holes. It can also allow various impurities to enter the drip holes, leading to blockage. Because existing U-shaped clips lack effective protection mechanisms for the drip holes, they are unable to withstand such external interference. This not only reduces the irrigation efficiency of the drip irrigation tape but also shortens its lifespan, increasing agricultural production costs and maintenance workload.

[0005] Chinese utility model patent publication number CN209882727U discloses a surface drip irrigation tape fixing device for use in desert areas, including an upper buckle body and a lower buckle body; the upper buckle body is a cover structure; the lower buckle body includes a groove and a positioning part; the positioning part consists of a support frame and a positioning post, with the support frame and positioning post connected as an integral structure; the cover structure is fastened to the groove, and the groove is fixedly connected to the support frame. This utility model is used to fix the drip irrigation tape on the ground surface, but it does not solve the problem of protecting the drip holes in the fixing device. Utility Model Content

[0006] The technical problem to be solved by this invention is that existing drip irrigation tape fixing devices cannot provide protection for the drip holes. To address this, a semi-fixed drip irrigation tape is provided.

[0007] The technical solution of this utility model is: a semi-fixed drip irrigation tape, including a drip irrigation tape body and drip holes opened on the top of the drip irrigation tape body; the drip irrigation tape body is provided with a semi-fixed component to block the drip holes, the semi-fixed component includes a U-shaped limiting plate covering the surface of the drip irrigation tape body, the U-shaped limiting plate includes a horizontal section covering the drip holes and vertical sections located at both ends of the horizontal section, the inner surface of the horizontal section is provided with two arc-shaped protective plates that fit the drip irrigation tape body and surround the drip holes, and the inner surface of the horizontal section between the two arc-shaped protective plates is provided with an upwardly raised arc-shaped groove.

[0008] In the above scheme, at least one vertical segment has a centrally located mounting groove communicating with the end of that segment. At least one vertical segment has two sides with fixing holes communicating with the mounting groove. A U-shaped limiting plate located on one side of the fixing hole has a sliding groove communicating with the fixing hole and closed at both ends. A positioning rectangular block is slidably fitted inside the fixing hole. One end of the positioning rectangular block is fixedly connected to an operating block located outside the vertical segment. A slider located in the sliding groove is fixedly connected to one side of the positioning rectangular block. A spring connects the slider to one closed end of the sliding groove. An mounting block is fitted inside the mounting groove. Positioning grooves that mate with the positioning rectangular block are located on both sides of the mounting block. A pressure plate is fixedly connected to the bottom of the mounting block. Several fixing posts are fixedly connected to the bottom of the pressure plate.

[0009] In the above scheme, an installation groove communicating with the end of each of the two vertical segments is provided in the center of the interior, and a fixing hole communicating with the installation groove is provided on both sides of each of the two vertical segments.

[0010] The improvement to the above scheme is that several barbs are fixed to the fixed pile.

[0011] In the above scheme, the end of the positioning rectangular block that mates with the positioning groove is wedge-shaped.

[0012] In the above scheme, a sealing gasket is provided on the contact surface between the operating block and the outer surface of the vertical section.

[0013] In the above scheme, a sealing gasket is provided on the contact surface between the top of the pressure plate and the bottom of the vertical section.

[0014] A further improvement to the above solution is that the top and bottom of the operating block are provided with several anti-slip grooves.

[0015] A further improvement to the above solution is that a pull ring is provided at the top of the horizontal section.

[0016] The beneficial effects of this utility model are achieved through the coordinated use of the drip irrigation tape body, semi-fixed component, drip holes, U-shaped limiting plate, arc-shaped protective plate, and arc-shaped groove. The arc-shaped protective plate and arc-shaped groove work together to prevent the inner surface of the U-shaped limiting plate from contacting the drip holes, ensuring unobstructed dripping and providing protection, allowing the dripping water to fall smoothly into the farmland. The U-shaped limiting plate has a large cross-sectional area, providing good shielding and protection for the drip holes and reducing external influences. Multiple fixing stakes enhance the connection strength, achieving better protection and semi-fixation, improving irrigation efficiency, and reducing agricultural costs and maintenance workload. Through the coordinated use of the operating block, installation block, positioning groove, mounting groove, fixing hole, positioning rectangular block, slider, spring, and sliding groove, the detachable design of the semi-fixed component offers significant advantages during the inspection and maintenance of the drip irrigation tape body. It is not necessary to pull the entire tape out of the soil; by pulling the operating block to detach the positioning rectangular block from the positioning groove, the U-shaped limiting plate can be disassembled individually, releasing the semi-fixed constraint on the drip irrigation tape body and maintaining the connection between the component and the ground. After maintenance, only the U-shaped limit plate and pressure plate need to be reassembled, saving time and manpower. It is easy to operate and highly practical. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A semi-fixed drip irrigation tape includes a drip irrigation tape body 1 and drip holes 3 formed on the top of the drip irrigation tape body. The drip irrigation tape body is provided with a semi-fixed component 2 that blocks the drip holes. The semi-fixed component includes a U-shaped limiting plate 7 covering the surface of the drip irrigation tape body. The U-shaped limiting plate includes a horizontal section covering the drip holes and vertical sections located at both ends of the horizontal section. The inner surface of the horizontal section is provided with two arc-shaped protective plates 12 that fit against the drip irrigation tape body and surround the drip holes. The inner surface of the horizontal section between the two arc-shaped protective plates is provided with an upwardly raised arc-shaped groove 13. A plurality of drip holes 3 are evenly spaced and uniformly formed on the outer wall of the drip irrigation tape body 1, and a semi-fixed component 2 is fitted onto each drip hole.

[0021] As an embodiment of this utility model, the two vertical sections of the U-shaped limiting plate can be of different lengths. The longer vertical section has a mounting groove 14 in the center that communicates with the end of the longer section. At least one vertical section has a fixing hole 15 on each side that communicates with the mounting groove. The U-shaped limiting plate located on one side of the fixing hole has a sliding groove 19 that communicates with the fixing hole and is closed at both ends. A positioning rectangular block 16 is slidably fitted in the fixing hole. One end of the positioning rectangular block is fixedly connected to an operating block 9 located outside the vertical section. A slider 17 located in the sliding groove is fixedly connected to one side of the positioning rectangular block. A spring 18 is connected between the slider and one closed end of the sliding groove. An mounting block 10 is adapted in the mounting groove. Positioning grooves 11 that cooperate with the positioning rectangular block are opened on both sides of the mounting block. A pressure plate 4 is fixedly connected to the bottom of the mounting block. Several fixing posts 5 are fixedly connected to the bottom of the pressure plate.

[0022] As a variation of the above embodiment, the two vertical segments can also be symmetrically distributed, each vertical segment having the above-mentioned mounting groove 14, fixing hole 15, sliding groove 19, positioning rectangular block 16, operating block 9, slider 17, spring 18, mounting block 10, positioning groove 11, pressure plate 4 and fixing post 5.

[0023] As an embodiment of this utility model, the fixed pile is fixed with several barbs 6, which can enhance the friction between the fixed pile 5 and the soil, improve the stability of the semi-fixed component 2, and prevent it from loosening and shifting.

[0024] As an embodiment of this utility model, the end of the positioning rectangular block that cooperates with the positioning groove is wedge-shaped, so as to realize the quick snap-fit ​​positioning of the U-shaped limiting plate 7 and the mounting block 10, thereby improving the assembly efficiency.

[0025] As an embodiment of this utility model, a sealing gasket is provided on the contact surface between the operating block 9 and the outer surface of the U-shaped limiting plate 7, and a sealing gasket is provided on the contact surface between the top of the pressure plate 4 and the bottom of the U-shaped limiting plate 7. This can prevent dust, water and other impurities from entering the interior of the semi-fixed component 2, avoid affecting the normal operation of the moving parts of the component such as the positioning rectangular block 16 and the slider 17, extend the service life of the component, and enhance the overall stability of the semi-fixed component 2.

[0026] As an embodiment of this utility model, the top and bottom of the operating block 9 are provided with several anti-slip grooves, which can increase the friction between the hand and the operating block 9, making it easier for the user to pull the operating block 9, and making the disassembly of the U-shaped limiting plate 7 easier and more convenient.

[0027] As an embodiment of this utility model, the top of the horizontal section is provided with a pull ring 8, which facilitates user operation and makes it easier to pull the semi-fixed component 2 out of the soil.

[0028] The above embodiments can be combined arbitrarily as needed, and as long as the resulting technical solutions do not conflict, they all fall within the protection scope of this utility model.

[0029] The working principle of this utility model is as follows: All parts not described herein are the same as or can be implemented using existing technology. In use, the drip irrigation tape body 1 is precisely laid in the farmland according to a pre-planned path, ensuring that the drip holes 3 are facing upwards. Subsequently, the operator uses multiple semi-fixed components 2 to perform semi-fixation work on the drip irrigation tape body 1. Based on the specific position of the drip holes 3, the fixing stakes 5 at the bottom of the pressure plate 4 are inserted into the soil, thereby achieving stable fixation of the semi-fixed components 2. At this time, the drip irrigation tape body 1 is confined within the internal space of the U-shaped limiting plate 7. Simultaneously, the arc-shaped protective plate 12 inside the U-shaped limiting plate 7 contacts the drip irrigation tape body 1, connecting the drip holes 3 with the interior of the arc-shaped groove 13. During the installation of the semi-fixed components 2, this structural design effectively prevents the inner surface of the U-shaped limiting plate 7 from directly contacting the drip holes 3, thus preventing blockage of the drip holes 3. The arc-shaped protective plate 12 and the arc-shaped groove 13 work together to ensure the unobstructed flow of the drip holes 3 and provide more effective protection for them. During subsequent irrigation, water dripping from the drip holes 3 flows out through the arc-shaped groove 13 and drips down the outer wall of the drip irrigation tape into the farmland. Furthermore, compared to traditional U-shaped clips, the U-shaped limiting plate 7, when partially fixing the drip irrigation tape, has a larger cross-sectional area, thus providing more significant protection for the drip holes 3 on the drip irrigation tape body 1, effectively reducing the adverse effects of external factors on the drip holes 3. Simultaneously, the installation of multiple fixing stakes 5 enhances the connection strength between the semi-fixed component 2 and the soil, enabling the semi-fixed component 2 to achieve better protection and semi-fixation of the drip irrigation tape body 1, thereby improving the irrigation efficiency of the drip irrigation tape and reducing agricultural production costs and maintenance workload.

[0030] The drip irrigation tape body 1 is typically used outdoors. When a section of the drip irrigation tape body 1 is damaged and requires repair or maintenance, the corresponding semi-fixed component 2 needs to be disassembled. The user can directly apply a pulling force to the two operating blocks 9 on the outside of the U-shaped limiting plate 7. The movement of the operating blocks 9 causes the positioning rectangular block 16 to slide within the fixing hole 15. The sliding of the positioning rectangular block 16 further drives the slider 17 to slide on the slide groove 19 and exerts a squeezing effect on the spring 18. As the positioning rectangular block 16 continues to move, it will disengage from the locking position of the positioning groove 11 on the mounting block 10. At this time, simply pull the U-shaped limiting plate 7 upward to pull the mounting block 10 out of the mounting groove 14, thus completing the disassembly between the U-shaped limiting plate 7 and the pressure plate 4. This method eliminates the need to remove the semi-fixed component 2 entirely from the soil. The U-shaped limiting plate 7 and pressure plate 4 on the semi-fixed component 2 can be detached individually, releasing the semi-fixed constraint on the drip irrigation tape body 1 while maintaining the connection between the semi-fixed component 2 and the ground. After subsequent maintenance, the step of re-inserting the semi-fixed component 2 into the soil is eliminated; only the U-shaped limiting plate 7 and pressure plate 4 need to be reassembled. This saves time and manpower and is characterized by its ease of operation and high practicality.
