Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation equipment technology, specifically relating to an integrated quantitative flow control device for drip irrigation connectors. Background Technology

[0002] Drip irrigation is a highly precise water-saving irrigation method. Its core principle is to deliver filtered and pressurized water directly, slowly, and evenly to the soil area where crop roots are most concentrated through a low-pressure pipeline system. It utilizes a network of pipes laid in the field or buried underground, along with precisely designed drippers or drip tapes, to continuously or intermittently moisten the root zone soil with extremely small flow rates. This localized water supply method minimizes water loss through evaporation, surface runoff, and deep seepage during transport, resulting in significantly more water-saving effects compared to traditional surface irrigation, typically saving 30% to 60% of water.

[0003] Simultaneously, drip irrigation can be perfectly combined with fertigation technology. Through a fertilization device, nutrients are injected synchronously into the irrigation water as needed, ensuring precise delivery of water and fertilizer directly to the crop roots. This significantly improves water and fertilizer utilization efficiency, reducing fertilizer waste and environmental pollution risks caused by leaching. Furthermore, it significantly promotes crop growth, improves quality, and increases yield. In addition, drip irrigation effectively suppresses weed growth, reduces soil compaction, and lowers field humidity, thereby mitigating some diseases. It is particularly suitable for water-scarce areas, facility agriculture, hilly slopes, and the cultivation of high-value cash crops, making it a key technology for achieving efficient, sustainable, and modern agricultural production.

[0004] Typical drip irrigation equipment includes a water tank, a water pump, a main pipe, branch pipes, and drip tape. The water pump fills the main pipe with water from the tank, which then delivers the water to the drip tape through the branch pipes for irrigation. The drip tape and branch pipes are usually connected by switches. Because the connection points between each branch pipe and the main pipe are different, the water pressure and flow rate of each branch pipe are different. This may result in different irrigation amounts in different areas of the farmland, which may cause crops to grow at different rates, affecting the overall quality of the crop population. Therefore, it is necessary to improve existing drip irrigation equipment. Utility Model Content

[0005] The purpose of this invention is to provide an integrated quantitative flow control device for drip irrigation connectors to solve the problem that the water pressure and flow rate of each drip irrigation tape are not equal due to the difference in distance between each drip irrigation tape and the water pump outlet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A drip irrigation connector with integrated quantitative flow control adjustment device, comprising: The casing is composed of two mounting shells connected together, and a retaining ring is fixedly connected to each mounting shell; An adjustment disc is connected inside the mounting housing, and the adjustment disc has multiple adjustment holes of different diameters; A turntable is rotatably connected inside the mounting housing, and a water-permeable hole is provided on the turntable. The side wall of the turntable is in close contact with the side wall of the adjustment plate, and the turntable is configured to connect the water-permeable hole and the adjustment hole by rotation. A rotating drum is rotatably connected to the mounting housing and to the turntable, and a connecting pipe is fixedly connected to the rotating drum.

[0007] Preferably, the ends of the two mounting shells are threaded together.

[0008] Preferably, multiple adjusting holes of different diameters are arranged in a ring array on the adjusting plate, and the adjusting plate and the abutment ring are fixedly connected by bolts.

[0009] Preferably, the turntable and the rotating cylinder are fixedly connected by bolts.

[0010] Preferably, a rubber waterproof ring is snapped onto the outer wall of the turntable, and the rubber waterproof ring abuts against the inner wall of the mounting housing.

[0011] Preferably, a convex ring is fixedly connected to the outer wall of the mounting shell, and a retaining ring is fixedly connected to the convex ring by bolts, and the end of the rotating drum is rotatably engaged between the retaining ring and the convex ring.

[0012] Preferably, a screen cylinder is snapped between the two mounting shells.

[0013] Preferably, the outer surface of the rotating drum has friction grooves, and the connecting pipe has threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention features two sets of adjusting discs and turntables inside the casing. Users can install the casing between the branch pipes and the drip irrigation tapes. When the flow rate of each drip irrigation tape is adjusted to the same level, the turntables corresponding to different drip irrigation connectors can be rotated to align the permeable holes on the turntables with the adjusting holes of different diameters on the adjusting discs. This changes the water flow area at one end of the casing, ensuring that the water flow rate and velocity from each branch pipe into the casing are identical. This effectively prevents differences in growth rates among crops along different drip irrigation tapes due to varying water supply. Users can also adjust the outlet pressure of the drip irrigation tapes using the turntables and adjusting discs at the other end of the connectors, allowing for flexible adjustments to the drip irrigation strategy based on environmental differences.

The side wall of the turntable 4 is in close contact with the side wall of the adjusting plate 3, and the turntable 4 is configured to connect the water-permeable hole 41 and the adjusting hole 31 by rotation. The rotating drum 8 is rotatably connected to the mounting shell 1 and connected to the turntable 4. A connecting pipe 9 is fixedly connected to the rotating drum 8.

[0018] As can be seen from the above, by setting two sets of adjusting discs 3 and rotating discs 4 inside the casing, the user can install the casing between the branch pipes and the drip irrigation tapes. When the user adjusts the flow rate of each drip irrigation tape to the same level, the rotating disc 4 corresponding to different drip irrigation connectors can be rotated so that the water permeable hole 41 on the rotating disc 4 corresponds to the adjusting hole 31 of different diameter on the adjusting disc 3, thereby changing the water flow area at one end of the casing, so that the water flow rate into the casing from each branch pipe is the same, avoiding the growth difference of crops corresponding to different drip irrigation tapes due to different water conditions. Afterwards, the user can also adjust the water pressure of the drip irrigation tape through the rotating disc 4 and adjusting disc 3 at the other end of the connector, which makes it convenient for the user to flexibly adjust the drip irrigation strategy according to environmental differences.

[0019] Please see Figure 2 - Figure 4 As shown, the two mounting shells 1 are threaded together at their ends, and a screen cylinder 10 is snapped between the two mounting shells 1.

[0020] Multiple regulating holes 31 with different diameters are arranged in a ring array on the regulating plate 3. The regulating plate 3 and the abutment ring 2 are fixedly connected by bolts. The diameter of the water-permeable hole 41 is larger than the diameter of any one of the regulating holes 31. The user can rotate the turntable 4 to change the regulating hole 31 that is connected to the water-permeable hole 41. By changing the diameter of the regulating hole 31, the water flow rate entering the mounting shell 1 can be adjusted.

[0021] The turntable 4 and the rotating cylinder 8 are fixedly connected by bolts, and the user can rotate the rotating cylinder 8 to drive the turntable 4 to rotate.

[0022] A rubber waterproof ring 5 is snapped onto the outer wall of the turntable 4, and the rubber waterproof ring 5 abuts against the inner wall of the mounting shell 1 to improve the sealing performance of the mounting shell 1 and prevent water leakage.

[0023] A protruding ring 6 is fixedly connected to the outer wall of the mounting shell 1. A retaining ring 7 is fixedly connected to the protruding ring 6 by bolts. An annular groove is formed between the retaining ring 7 and the protruding ring 6. The end of the rotating cylinder 8 is rotatably engaged in the annular groove between the retaining ring 7 and the protruding ring 6.

[0024] The rotating drum 8 has friction grooves on its exterior, which can increase the friction of the outer wall of the rotating drum 8 and make it easier for the user to rotate the rotating drum 8. The connecting pipe 9 has threads.
