Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape, specifically a patch fixing device for an inlaid drip irrigation tape. Background Technology

[0002] Drip irrigation tape uses plastic pipes (drip irrigation tubes) to deliver water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. It drips water drop by drop, evenly and slowly, into the soil near the crop roots through drippers or drip tape with very small outflow orifices, keeping the soil in the most developed root zone at a suitable level of moisture. Drip irrigation tape is divided into patch drip irrigation tape, embedded cylindrical drip irrigation tube, labyrinth drip irrigation tape, blue track drip irrigation tape, etc.

[0003] Currently, the flow or bending of water within the drip irrigation tape leads to poor patch fixation. Furthermore, the current patches are not convenient for guiding water flow, resulting in greater impact from the water flow and causing the patches to loosen or detach easily. This affects the stability and ease of patch fixation. Therefore, it is necessary to design an inlaid patch fixing device for drip irrigation tape to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a patch fixing device for an inlaid drip irrigation tape to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a patch fixing device for an inlaid drip irrigation tape, comprising a drip irrigation tape body, wherein a patch plate for drip irrigation is embedded in the inner side wall of the body, and a fixing member is installed between the patch plate and the body.

[0006] Preferably, the fastener includes three sets of evenly arranged fixing blocks fixedly connected to the bottom of the patch plate, bonding plates extending from both sides of the patch plate, fixing strips fixedly connected to the bottom of the bonding plates, and the patch plate and the body are installed by hot-melt pressing.

[0007] Preferably, the surface of the patch plate is provided with a flow guide groove, one end of the flow guide groove is provided with a flow slowing groove, and three drip nozzles are fixedly connected to the bottom of the flow slowing groove in a uniform arrangement. The flow guide groove is arranged in a serpentine shape.

[0008] Preferably, the drip nozzle has a backstop ring extending from its bottom.

[0009] Preferably, a filter grid is embedded on the inner side of the other end of the guide channel.

[0010] Preferably, flow portions are provided at both ends of the patch plate and at the edge of the bonding plate.

[0011] Preferably, the inner side of the drip nozzle is provided with two flow guides, and four drip holes arranged in a circle are opened on one side of the flow guides.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. After the patch plate is heat-fused and embedded into the inner wall of the main body, the fasteners snap the patch plate and the main body together, thus doubly fixing the patch plate and the main body. The patch plate can facilitate the flow of water and prevent the patch plate from loosening due to water flow impact.

[0014] 2. The fixing block has an isosceles trapezoidal cross-section, with the bottom diameter being larger than the top diameter. This increases the contact area between the body and the fixing block after the body is hot-melted. The bonding plates extending from both sides of the patch plate increase the tightness of the bonding between the patch plate and the body. The fixing strips can increase the contact area between the bonding plate and the body. Thus, after the body is hot-melted, it is squeezed to fit tightly into the patch plate. As a result, the bottom plate of the body is pressed into multiple grooves by the fixing strips and fixing blocks to improve the stability of the bonding plate and the body during installation and fixation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please refer to Figure 1-8 As shown, this utility model provides a patch fixing device for an inlaid drip irrigation tape, including a drip irrigation tape body 1, a patch plate 2 for drip irrigation is embedded in the inner side wall of the body 1, and a fixing member is installed between the patch plate 2 and the body 1.

[0027] Furthermore, after the patch plate 2 is heat-fused and embedded into the inner wall of the body 1, the fasteners snap the patch plate 2 and the body 1 together, thereby doubly fixing the patch plate 2 and the body 1. The patch plate 2 can facilitate the flow of water and prevent the water flow from impacting and loosening the patch.

[0028] Specifically, the fasteners include three sets of evenly arranged fixing blocks 3 that are fixedly connected to the bottom of the patch plate 2, and bonding plates 4 extending from both sides of the patch plate 2. The bottom of the bonding plates 4 is fixedly connected to a fixing strip 5. The patch plate 2 and the body 1 are installed by hot-melt pressing.

[0029] Among them, the cross-section of the fixing block 3 is an isosceles trapezoid, and the bottom diameter of the fixing block 3 is larger than the top diameter, which increases the contact area between the body 1 and the fixing block 3 after the body 1 is hot-melted. The bonding plates 4 extending on both sides of the bonding plate 2 increase the tightness of the bonding plate 2 and the body 1. The fixing strip 5 can increase the contact area between the bonding plate 4 and the body 1. Thus, after the body 1 is hot-melted, the body 1 is squeezed to fit tightly with the bonding plate 2. Thus, the bottom plate of the body 1 is pressed into multiple grooves by the fixing strip 5 and the fixing block 3 to improve the stability of the bonding plate 4 and the body 1 during installation and fixation.

[0030] More specifically, the surface of the patch plate 2 is provided with a flow guide groove 6, one end of the flow guide groove 6 is provided with a slow flow groove 7, and three drip nozzles 8 are fixedly connected to the bottom of the slow flow groove 7. The flow guide groove 6 is arranged in a serpentine shape. A filter grid 10 is embedded in the inner side of the other end of the flow guide groove 6. Flow parts 11 are provided at both ends of the patch plate 2 and the edge of the bonding plate 4. Two flow guide parts 12 are provided inside the drip nozzles 8. Four drip holes 13 arranged in a circle are provided on one side of the flow guide parts 12.

[0031] The filter 10 filters the water entering the guide channel 6, preventing impurities in the water from affecting the smoothness of the water flow in the guide channel 6. The water flows through the guide channel 6 through multiple bends to control the drip rate. The water enters the slow flow channel 7 through the guide channel 6. The three drip nozzles 8 at the bottom of the slow flow channel 7 can drip the water downwards. The flow parts 11 at both ends of the patch plate 2 and both sides of the bonding plate 4 are arc-shaped, making the patch plate 2 streamlined as a whole, so as to facilitate the flow of water and reduce the impact of the water flow on the patch plate 2.

[0032] Furthermore, the two guide sections 12 provided on the top and bottom of the drip nozzle 8 are conical, so that water can flow through the drip holes 13 on the side of the guide section 12 and drip out, avoiding obstruction of water flow.

[0033] It should be added that the bottom of the drip nozzle 8 has a retaining ring 9, which is integrally formed with the bottom of the drip nozzle 8. When the patch plate 2 is fitted with the body 1, the drip nozzle 8 is pressed down and extends out of the bottom of the body 1, so that the retaining ring 9 clamps and fixes the body 1 and the drip nozzle 8, thereby enabling the patch plate 2 and the body 1 to be snapped and fixed again, improving the stability of fixing the patch plate 2.

[0034] Working principle: First, the patch plate 2 is placed inside the body 1. Then, the body 1 is locally baked and heat-melted. Then, the patch plate 2 is pressed and pressed against the bottom of the body 1. Next, the body 1 is fitted with the fixing block 3. At this time, the bonding plates 4 extending from both sides of the patch plate 2 are fitted with the body 1. At the same time, after the body 1 is heat-melted, it is pressed and tightly fitted with the patch plate 2. Also, the bottom plate of the body 1 is pressed into multiple grooves by the fixing strip 5 and the fixing block 3. At the same time, the patch plate 2 drives the drip nozzle 8 to pass through the body 1. Then, the anti-reverse ring 9 on the outer edge of the drip nozzle 8 presses the body 1 and the drip nozzle 8 tightly.

[0035] Furthermore, when the water flows within the main body 1, it flows through the guide section 12 on the upper surface of the patch plate 2. Some of the water flows through the filter grid 10 and into the guide channel 6. Then, the water flows through the guide channel 6 into the slow-flow channel 7, and then through the three drip nozzles 8 at the bottom of the slow-flow channel 7 for drip irrigation.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
