Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, and in particular to a drip irrigation device for vegetable planting that is easy to adjust. Background Technology

[0002] Drip irrigation for vegetables is a highly efficient irrigation method. It delivers pressurized water through drippers installed on capillary tubes, allowing it to drip evenly and slowly into the soil near the roots of crops. This precise delivery of water to the root system minimizes water evaporation and loss, improving water use efficiency. Compared to traditional furrow or flood irrigation, drip irrigation provides water precisely according to the water needs of vegetables, thus saving water.

[0003] In existing technologies, drip irrigation typically uses water pipes with drip heads installed directly on the ground for drip irrigation. The operating pressure is usually 50–150 kPa to avoid energy waste or pipe rupture caused by high pressure. The dripper flow rate is generally 1–10 L / h. By controlling the dripper spacing and flow rate, localized moist zones are created in the soil, reducing evaporation and deep seepage. Capillary tubes and drippers are usually laid on the ground for easy observation and maintenance, suitable for open-field crops and fruit trees. It can also be used in conjunction with mulch film to reduce air humidity and lower the risk of pests and diseases, making it suitable for vegetables and flowers.

[0004] However, existing drip irrigation systems for vegetable cultivation typically lay pipes on the soil surface, with the water outlet positioned close to the neck of the organic vegetables. Tiny streams of water drip into the soil through perforations in the delivery pipe, achieving localized irrigation via capillary action. However, this type of drip irrigation has significant limitations. Once the perforations are made in the delivery pipe, the drip position is fixed and cannot be adjusted. When changing crops or adjusting planting spacing later, the perforation spacing cannot be changed simultaneously; the entire pipe must be replaced, significantly increasing replacement costs.

[0005] Therefore, we propose an easily adjustable drip irrigation device for vegetable cultivation to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an easily adjustable drip irrigation device for vegetable cultivation, which solves the problem that existing drip irrigation pipes need to be replaced as a whole when changing crops or planting spacing, resulting in high replacement costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A drip irrigation device for vegetable cultivation that is easy to adjust includes a water supply pipe, a plurality of water distribution pipes connected to the outer wall of the water supply pipe, a plurality of universal bamboo joint pipes arranged in a linear array connected to the bottom of the water distribution pipes, and a drip irrigation head connected to the bottom of the universal bamboo joint pipes.

[0009] Preferably, the inner wall of the water distribution pipe is provided with a plurality of water-blocking rings, the water-blocking rings are arc-shaped, and the plurality of water-blocking rings are respectively located at the top of a plurality of universal bamboo joint pipes.

[0010] Preferably, a square column is fixedly connected to the outer wall of the water-blocking ring, and the water distribution pipe has an adjustment groove that matches the square column. One end of the square column passes through the adjustment groove and is fixedly connected to an adjustment column.

[0011] Preferably, each of the plurality of water-blocking rings has two sliders fixedly connected to its outer wall, the sliders are symmetrically distributed, and the inner wall of the water distribution pipe is provided with a groove that matches the sliders.

[0012] Preferably, the bottom of the water distribution pipe is provided with several support legs, the top of the support legs is fixedly connected to a second clamping plate, a first clamping plate is installed on one side of the second clamping plate by bolts, and the water distribution pipe is installed between the second clamping plate and the first clamping plate.

[0013] Preferably, a base plate is fixedly connected to the bottom of the support leg, and a fixing cone is fixedly connected to each of the four corners of the bottom of the base plate.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. The design of the water-retaining ring and the universal bamboo-joint tube allows for individual control of the opening and closing of each drip head. This precise control enables flexible adjustment of the working status of individual drip heads to meet the water requirements of different crops, thus achieving adjustable drip spacing. This design is widely adaptable to the growth needs of various crops and the spacing requirements of different planting patterns. Furthermore, since drip irrigation only needs to deliver water to the neck of the crop, eliminating the need for drip irrigation on the leaves, the plasticity of the universal bamboo-joint tube allows for precise control of the drip head's desired drip position within a certain range. This enables precise drip irrigation of crops, improves irrigation efficiency, and saves water.

[0016] 2. The design of the support legs allows for quick installation and disassembly of the support legs and the water distribution pipe using the bolts between the first and second clamping plates. This prevents the water distribution pipe from directly contacting the ground, thus avoiding damage or wear from debris and accelerated aging of the pipe due to prolonged contact with damp soil. Furthermore, it allows the universal bamboo-joint pipe to be separated from the ground, ensuring sufficient adjustment range and preventing mud or debris from entering the drip irrigation head and causing blockage.

[0017] 3. The design of the fixed cone allows it to extend into the soil, ensuring the stability of the base plate. At the same time, the fixed cone, in conjunction with the flat surface of the base plate, prevents the support legs from sinking under different humidity conditions, ensuring the stability of the support legs and preventing the water distribution pipe from tipping over during drip irrigation.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Reference Figure 1-5A drip irrigation device for vegetable cultivation that is easy to adjust includes a water supply pipe 1, which is made of high-density polyethylene (HDPE). This material has the advantages of high hardness and high strength, and is often used in main or branch pipes to carry water. It has strong water pressure resistance and is suitable for drip irrigation systems in large-area farmland. Several branch pipes 2 are connected to the outer wall of the water supply pipe 1. The branch pipes 2 are made of low-density polyethylene (LDPE), which has the advantages of soft texture and good toughness. Several universal bamboo-joint pipes 3 arranged in a linear array are connected to the bottom of the branch pipes 2. The bamboo-joint tube 3 is made of a combination of alternating plastic and silicone materials, ensuring that it has good plasticity while providing a certain degree of support. Since drip irrigation only needs to drip water to the neck of the crop and does not need to drip water to the leaves, the plasticity of the universal bamboo-joint tube 3 allows for precise control of the drip position of the drip head within a certain range, enabling precise drip irrigation of crops, improving the efficiency of drip irrigation, and avoiding water waste. The bottom of the universal bamboo-joint tube 3 is connected to the drip head 4, which ensures that the water drips in droplets when it flows out.

[0027] Furthermore, the inner wall of the water distribution pipe 2 is provided with several water-retaining rings 12. The water-retaining rings 12 are made of high-density polyethylene (HDPE) to ensure good strength and support. The water-retaining rings 12 are arc-shaped and have an opening at the bottom. When it is necessary to connect the universal bamboo joint pipe 3, the opening at the bottom of the water-retaining ring 12 can be aligned with the water inlet of the universal bamboo joint pipe 3 to allow water to flow into the universal bamboo joint pipe 3. The several water-retaining rings 12 are located on the top of several universal bamboo joint pipes 3 respectively. The water-retaining rings 12 cooperate with the universal bamboo joint pipe 3 to control the connection and disconnection between the universal bamboo joint pipe 3 and the water distribution pipe 2.

[0028] Furthermore, a square column 10 is fixedly connected to the outer wall of the water-retaining ring 12, and an adjustment groove 13 matching the square column 10 is provided on the water distribution pipe 2. The square column 10 is rectangular, and the adjustment groove 13 matches the square column 10. The adjustment groove 13 can provide guidance for the square column 10. One end of the square column 10 passes through the adjustment groove 13 and is fixedly connected to an adjustment column 8. The adjustment column 8 can facilitate the adjustment of the water-retaining ring 12 by the planting personnel.

[0029] Furthermore, each of the several water-blocking rings 12 has two sliders 11 fixedly connected to its outer wall. The sliders 11 are made of silicone, which has the advantages of high temperature resistance, low temperature resistance, corrosion resistance, non-toxicity, odorless, high safety, strong anti-aging properties, long service life, no odor, and no release of harmful substances. In cooperation with the sliding groove 14, it can not only provide guidance for the water-blocking ring 12 and prevent the water-blocking ring 12 from displacing horizontally, but also have a good waterproof effect due to the tight fit between the sliders 11 and the sliding groove 14. It can prevent water from flowing out from the gap between the water-blocking ring 12 and the water distribution pipe 2, reducing the waste of water resources. The sliders 11 are symmetrically distributed, and the design of two sliders 11 can make both sides of the water-blocking ring 12 have a good waterproof effect. The inner wall of the water distribution pipe 2 is provided with a sliding groove 14 that matches the sliders 11.

[0030] Furthermore, the bottom of the water distribution pipe 2 is equipped with several support legs 5. The support legs 5 can lift the water distribution pipe 2 off the ground to prevent it from being scratched or worn by debris on the ground. At the same time, they can separate the universal bamboo joint pipe 3 from the ground to ensure that the universal bamboo joint pipe 3 has a sufficient adjustment range. They also prevent mud or debris from the ground from entering the drip irrigation head 4 and causing blockage. The top of the support leg 5 is fixedly connected to a second clamping plate 7. A first clamping plate 6 is installed on one side of the second clamping plate 7 by bolts. The water distribution pipe 2 is installed between the second clamping plate 7 and the first clamping plate 6. The first clamping plate 6 and the second clamping plate 7 can securely install the water distribution pipe 2 on the support leg 5. The first clamping plate 6 and the second clamping plate 7 are connected by bolts, which facilitates the installation and disassembly of the water distribution pipe 2 and facilitates the maintenance and storage of the drip irrigation equipment in the future.

[0031] Furthermore, a base plate 15 is fixedly connected to the bottom of the support leg 5. A fixing cone 9 is fixedly connected to each of the four corners of the bottom of the base plate 15. The fixing cone 9 can be inserted into the soil. The fixing cone 9 cooperates with the plane of the base plate 15, which allows the support leg 5 to adapt to soil with different moisture levels, so that the support leg 5 can stably support the water distribution pipe 2 and prevent the water distribution pipe 2 from tipping over during use.

[0032] In summary:

[0033] When irrigation is needed for crops, one end of the water supply pipe 1 is connected to an external water source. Several branch pipes 2 are arranged according to the distribution of crops. The end of the branch pipe 2 closest to the water supply pipe 1 is securely clamped using the first clamping plate 6, the second clamping plate 7, and bolts. Then, the fixing cone 9 at the bottom of the base plate 15 is inserted into the soil. A support leg 5 is installed at every other end for support, keeping the branch pipe 2 away from the ground. This avoids ground debris from scratching or abrading the branch pipe 2 and prevents the branch pipe 2 from being in contact with damp soil for a long time, which may accelerate the aging of the water pipe.

[0034] Depending on the planting spacing of the crops, it is optional to connect the universal bamboo joint pipe 3. When it is not necessary to connect the universal bamboo joint pipe 3, the grower only needs to manually turn the adjusting column 8. The adjusting column 8 will drive the square column 10 and the water-blocking ring 12 at its bottom to rotate. With the cooperation of the adjusting groove 13 opened on the water distribution pipe 2 and the square column 10, the water-blocking ring 12 will make a circular motion around the center of the water distribution pipe 2. When the unopened part of the water-blocking ring 12 moves above the universal bamboo joint pipe 3, the water inside the water distribution pipe 2 will not flow out from the blocked universal bamboo joint pipe 3, thus achieving the adjustment of dripping. The function of the irrigation spacing; the cooperation between the slider 11 on the outer wall of the water-blocking ring 12 and the groove 14 on the inner wall of the water distribution pipe 2 can, on the one hand, provide a limiting function for the water-blocking ring 12, allowing the water-blocking ring 12 to rotate better, and on the other hand, it can also provide a water-blocking function for the gap at the water-blocking ring 12 in the water distribution pipe 2, reducing water leakage between the water-blocking ring 12 and the water distribution pipe 2; and the shape of the universal bamboo tube 3 can be changed by pinching it, so that the drip irrigation head 4 can fit more closely to the roots of the vegetables, improve drip irrigation efficiency, and solve the drip irrigation water problem;

[0035] When drip irrigation is needed for different crops, since their planting spacing and drip irrigation requirements are different, it is only necessary to change the spacing of the connected universal bamboo joint tube 3 and adjust the shape of the universal bamboo joint tube 3 to adapt to the needs of different vegetables. This greatly reduces the cost of replacing water pipes in the traditional drip irrigation method, makes it more convenient for growers to use, and improves the efficiency of drip irrigation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
