Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a fertilizer and water irrigation pipeline connection device. Background Technology

[0002] In traditional irrigation operations, flexible hose diversion is widely used as the core water delivery method in farmland irrigation systems. According to documents such as "Irrigation and Drainage Engineering Technology for Connecting Sprinkler Irrigation Pipelines" and "Connection Method of Agricultural Irrigation Soft Water Pipes," this technology system achieves directional water delivery through flexible hoses, with bypass pipe connection technology being a crucial link in the construction of the branch network. However, in practice, existing technologies present significant inconveniences. Specifically, the installation of bypass pipes requires not only the use of specialized cutting tools to machine connecting slots in the main hose wall, but also precise matching of the bypass pipe's outer diameter, followed by mechanical connection via a rotating locking mechanism. This process relies on multiple specialized tools, is complex, and demands extremely high precision. According to statistics from "Water-Saving Irrigation Technology Connection Joints," a single-point connection operation takes three to five minutes. Furthermore, existing connection methods pose a risk of leakage. The rotating locking structure is prone to seal failure due to soil settlement or pipe wall deformation after long-term use, leading to increased leakage rates. Insufficient precision in the slot machining stage can directly cause leakage problems. When applied to irrigation projects covering thousands of acres, according to the pipeline density standard recorded in the "Overview of Water-Saving Irrigation Project in Daxu Town, Guigang City" (three to five connection points per acre), the connection process alone will consume twenty to fifty man-hours, which seriously restricts the efficiency of large-scale irrigation.

[0003] While existing technical solutions optimize irrigation timing through intelligent monitoring systems mentioned in "Water Conservancy Information Processing Technology Based on Farmland Water-Saving Irrigation Projects," the physical connection layer still relies on numerous tools and complex operations, and the technological bottleneck has not been overcome. In particular, "Problems and Countermeasures in the Management of Agricultural Water-Saving Irrigation Projects" points out that labor costs resulting from traditional connection methods account for 35% to 42% of total operation and maintenance costs, and leakage problems further increase water waste, becoming a key factor restricting the promotion of modern agricultural water-saving technologies. Against this backdrop, developing new rapid connection devices is of significant practical importance for improving the deployment efficiency of irrigation systems and reducing the risk of leakage. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing bypass pipe connections, such as "complex operation, easy leakage, and low efficiency," and to provide a fertilizer and water irrigation pipeline branching device that achieves "tool-free rapid installation, self-adaptive sealing, and stable locking" through structural optimization, thereby significantly improving the construction efficiency and operational stability of irrigation networks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bypass connector for fertigation pipelines includes a bypass connector body. A water outlet pipe is connected to the front end of the bypass connector body, and a water inlet pipe is connected to the rear end of the bypass connector body. An adjusting handle is provided on the top of the bypass connector body. A threaded rod and a threaded knob are provided on the water inlet pipe. A smooth area is provided on the water inlet pipe, located at the front end of the threaded rod. The threaded knob slides within the smooth area for adjustment. A locking component is provided on the threaded rod, allowing the threaded knob to rotate and abut against the water inlet pipe for secure fastening when the water inlet pipe is inserted into the irrigation pipeline.

[0006] Preferably, the threaded screw is located at the rear end of the water inlet pipe, the threaded knob can be rotated and adjusted on the threaded screw, and the diameter of the threaded screw is consistent with the diameter and width of the water inlet pipe.

[0007] Preferably, the locking component is configured as an elastic compression block, which is installed at the front end or middle of the threaded rod and is elastically connected by a spring provided inside the threaded rod.

[0008] Preferably, the number of elastic compression blocks is set to multiple, with at least four elastic compression blocks, which are evenly spaced and arranged around the threaded rod, and each elastic compression block protrudes from the outer peripheral wall of the threaded rod.

[0009] Preferably, the bottom of the threaded rod is provided with a cutting arc plate, and the number of the cutting arc plates is set to multiple, with a minimum of four, and they are arranged around each other at equal intervals.

[0010] Preferably, the end of the elastic compression block near the threaded knob is a planar structure, the end of the threaded knob near the elastic compression block is also a planar structure, and the other end of the elastic compression block away from the threaded knob is a curved arc structure.

[0011] Preferably, the sidewall of the cutting arc sheet is configured with a sharp edge structure, the overall diameter of the cutting arc sheet is smaller than the diameter of the water inlet pipe, and the bottom diameter of the cutting arc sheet gradually narrows along the axial direction and is also configured with a sharp edge structure.

[0012] Preferably, both the threaded rod and the cutting arc are made of rigid materials, the threaded rod is made of plastic, and the cutting arc is made of metal.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. The fertigation pipe tapping device described in this utility model achieves an installation process of "one-step embedding + rotation locking" through a combination structure of "cutting arc plate + elastic compression block". Operators do not need to carry tools such as cutters and wrenches. They only need to hold the bypass connector body, align the cutting arc plate at the bottom of the water inlet pipe with the irrigation pipe wall, apply axial force to complete the piercing and enlarging, and then rotate the threaded knob to abut against the elastic compression block to complete the fixing. The whole process is convenient and fast, and the efficiency of single-point operation is greatly improved compared with the traditional method, which greatly reduces the construction time of large-scale irrigation projects.

[0014] 2. The fertilizer and water irrigation pipe tapping device described in this utility model uses nitrile rubber as the elastic compression block, which has good elasticity and sealing performance. When the threaded knob is pressed against the elastic compression block, the compression block will fit tightly against the inner wall of the irrigation pipe due to the force, forming an "annular sealing strip". At the same time, the uniform distribution design of the elastic compression block ensures that the sealing force is evenly transmitted along the circumference of the interface, avoiding leakage caused by local poor sealing.

[0017] 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.

[0018] like Figures 1 to 4As shown, the present invention provides a 9-way connection device for fertigation pipelines, which is suitable for the construction of fertigation pipeline networks in large-scale farmland, orchards, greenhouses and other scenarios. It can realize the rapid and sealed connection between the main irrigation pipeline and the branch pipeline, which can greatly improve the deployment efficiency and operational stability of the irrigation system and reduce the waste of water resources and fertilizers.

[0019] The system includes a bypass connector body 1, with an integrally formed water outlet pipe 2 at its front end for connecting to a branch irrigation pipe to achieve fertilizer and water separation. A water inlet pipe 3 is coaxially connected to the rear end of the bypass connector body 1 for embedding into the main irrigation pipe 9 to introduce fertilizer and water. An adjusting handle 4 is rotatably connected to the top of the bypass connector body 1 for adjusting the flow rate of the water outlet pipe 2. Rotating the handle controls the opening and closing of the internal valve core, adapting to the irrigation needs of different crops. The water inlet pipe 3 has a threaded rod 5 and a threaded knob 6 arranged axially. The water inlet pipe 3 has a smooth area (located at the front end of the threaded rod 5, with a polished surface to reduce sliding resistance). The threaded knob 6 can slide axially within the smooth area for adjustment. A locking component is provided on the threaded rod 5. When the water inlet pipe 3 is embedded in the irrigation pipe 9, the rotation of the threaded knob 6 and the cooperation of the locking component achieve a tight seal between the water inlet pipe 3 and the irrigation pipe 9. Specifically, the threaded screw rod 5 is coaxially fixed to the rear end of the water inlet pipe 3, and its outer surface is machined with a trapezoidal thread (with a self-locking function to prevent the knob from loosening). The inner wall of the threaded knob 6 is provided with an internal thread that matches the threaded screw rod 5, and it can rotate on the threaded screw rod 5 and move axially. The diameter of the threaded screw rod 5 is consistent with the diameter of the water inlet pipe 3, ensuring that when the water inlet pipe 3 is embedded in the irrigation pipe 9, the threaded screw rod 5 can extend into the pipe at the same time, avoiding the embedding obstruction caused by the diameter difference. Furthermore, the locking component is set as an elastic compression block 7, which is made of nitrile rubber (with the characteristics of being resistant to aging and fertilizer corrosion, and suitable for agricultural irrigation environments). The elastic connection is achieved by a spring (made of stainless steel to prevent rust) preset inside the threaded rod 5. The elastic compression block 7 can be installed at the front end or middle of the threaded rod 5. In its initial state, it protrudes from the outer peripheral wall of the threaded rod 5 (the protrusion height is 2-3mm). When subjected to axial pressure, it can be compressed to be flush with the outer peripheral wall of the threaded rod 5, achieving an adaptive locking effect of "contracting when embedded and rebounding after being in place". The number of elastic compression blocks 7 is at least four, and they are evenly distributed around the circumference of the threaded rod 5. For example, the included angle between adjacent compression blocks is 90°. This angle can ensure that the locking force is evenly applied to the inner wall of the irrigation pipe 9, and avoid the interface tilting or leakage caused by uneven force. At the same time, the end of the elastic compression block 7 near the threaded knob 6 is set as a flat structure, which can increase the contact area with the threaded knob 6 and ensure stable pressure transmission, while the other end away from the threaded knob 6 is set as a curved arc structure, which can reduce the resistance when the water inlet pipe 3 is embedded in the irrigation pipe 9 and avoid scratching the pipe wall. At the bottom of the threaded rod 5 (i.e., the end furthest from the water inlet pipe 3), a cutting arc blade 8 is coaxially fixed. The number of cutting arc blades 8 is set to at least four, which are evenly distributed around the circumference of the threaded rod 5. The cutting arc blades 8 are made of 304 stainless steel (which has the characteristics of high strength and high sharpness and can easily cut agricultural hoses). Its side wall is processed with a sharp edge structure (the blade angle is 30° to ensure cutting efficiency). The overall diameter is smaller than the diameter of the water inlet pipe 3, for example, the difference is 1-2mm, to avoid too much waste material remaining on the pipe wall after cutting and clogging the interface. The bottom diameter is continuously narrowed along the axial direction (forming a conical structure). The bottom edge is also set with a sharp edge structure (thereby realizing the continuous action of "piercing first and then expanding the hole" without the need for additional cutting tools). The threaded swivel rod 5 is made of ABS engineering plastic, which has the characteristics of high strength and lightweight. It weighs only 1 / 3 of a metal swivel rod of the same size, making it easy for operators to hold and install. Its surface is coated with polytetrafluoroethylene, which can reduce the frictional resistance between the threaded knob 6 and the swivel rod, making the rotation adjustment smoother. The cut arc plate 8 is fixed to the threaded swivel rod 5 by injection molding, which can avoid the risk of falling off caused by traditional welding methods and ensure structural stability.

[0020] Working principle: First, the operator holds the bypass connector body 1 and aligns the cutting arc plate 8 at the bottom of the water inlet pipe 3 with the preset tap position of the irrigation pipe 9 (avoiding pipe folds or damage), and applies uniform pressure along the axial direction; the conical bottom of the cutting arc plate 8 first pierces the pipe wall, and as the pressure increases, the sharp edge of the side wall will cut the pipe wall in the circumferential direction to form a circular orifice that matches the diameter of the water inlet pipe 3, until the front end of the water inlet pipe 3 is completely embedded in the irrigation pipe 9 (at this time, the elastic compression block 7 shrinks to be flush with the outer peripheral wall of the threaded rod 5 due to the compression of the pipe wall).

[0021] Next, rotate the threaded knob 6 clockwise, causing it to move along the trapezoidal thread of the threaded rod 5 toward the elastic compression block 7; when the flat end of the threaded knob 6 contacts the flat end of the elastic compression block 7, continue rotating the knob to apply axial pressure; under the pressure, the elastic compression block 7 tightly adheres to the inner wall of the irrigation pipe 9, forming an annular sealing strip; when the knob can no longer be rotated (the resistance feels significantly increased), stop rotating it, at which point the water inlet pipe 3 and the irrigation pipe 9 have achieved a tight seal.

[0022] In summary, the 9-way connector for fertigation pipes provided by this utility model achieves a comprehensive breakthrough in overcoming the pain points of traditional bypass connection technology through an innovative structural combination of "cut arc plate 8 + elastic compression block 7 + trapezoidal threaded rod 5": In terms of operational efficiency, the entire process of "piercing-expanding-locking" can be completed without special tools, shortening the installation time at a single point and significantly improving efficiency compared to traditional methods, saving a significant amount of setup time for irrigation projects covering thousands of acres; In terms of sealing performance, the annular sealing band formed by the nitrile rubber elastic compression block 7, combined with the evenly distributed locking force design, reduces the leakage rate at the interface, effectively avoiding waste of water and fertilizer resources and soil water accumulation problems; In terms of adaptability and stability, it is compatible with commonly used agricultural irrigation hoses with an inner diameter of 20-50mm, covering most agricultural pipe specifications, and the application of trapezoidal thread self-locking function and corrosion-resistant materials (304 stainless steel cut arc plate 8, ABS engineering plastic rod) ensures stable operation of the device under environments such as soil vibration and fertilizer corrosion, extending its service life.
