Description

Technical Field

[0001] This utility model relates to the field of pear tree drip irrigation technology, and in particular to a pear tree drip irrigation device with adjustable flow rate. Background Technology

[0002] Drip irrigation systems for pear trees, as a type of water-saving irrigation equipment, are mainly used in pear tree cultivation. They deliver water precisely to the roots of pear trees via a pipeline system, effectively improving water resource utilization efficiency and meeting the water needs of pear tree growth. These drip irrigation systems typically include the following structure:

[0003] 1. Water source: This provides sufficient water for the drip irrigation system and generally includes reservoirs, wells, rivers, etc.

[0004] 2. The main hub consists of equipment such as water pumps, filters, fertilizer applicators, and pressure gauges. The water pumps are responsible for lifting the water source, the filters remove impurities from the water, the fertilizer applicators realize integrated water and fertilizer management, and the pressure gauges monitor the system pressure.

[0005] 3. The piping system consists of main pipes, branch pipes, and capillary pipes. The main pipes and branch pipes are mostly made of PVC or PE plastic pipes for water transportation. The capillary pipes are laid at the base of the pear trees and drippers are installed on them.

[0006] 4. The dripper is a key component that slowly drips water into the soil in the form of droplets.

[0007] Currently, to achieve efficient irrigation for pear trees, farmers and businesses have adopted various drip irrigation devices and methods. Some use fixed drip irrigation devices, which irrigate through underground pipes and drippers, and are characterized by good stability and resistance to damage. Others use mobile drip irrigation devices, which can be flexibly moved according to changes in the pear tree planting area, making it easy to adjust the irrigation range. Some areas use smart drip irrigation devices, which are equipped with sensors and control systems that can monitor soil moisture and pear tree water requirements in real time and automatically adjust the irrigation amount.

[0008] However, the above-mentioned implementation methods still have the following problems. In terms of flow regulation, the flow regulation function of most drip irrigation devices is relatively simple, making it difficult to accurately adjust according to the water requirements of pear trees at different growth stages and the amount of water evaporation under different weather conditions, resulting in water waste or insufficient irrigation. In terms of disassembly and maintenance, the components of existing drip irrigation devices are mostly connected in a fixed manner. When the water emitter, pipes and other components are blocked or damaged, disassembly and maintenance operations are complicated, consuming a lot of manpower and time costs, which seriously affects the normal operation and service life of the drip irrigation system. This pear drip irrigation device effectively solves the above problems through adjustable flow and disassembly design. The adjustable flow function can control the amount of irrigation water, improve water resource utilization efficiency, and promote pear tree growth. The disassembly design facilitates the maintenance, cleaning, adjustment and transportation and storage of the device, reduces the cost of use, improves the service life of the equipment and the flexibility of the system, and provides a better solution for irrigation management of pear tree planting. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an adjustable flow rate drip irrigation device for pear trees. This solves the problem that most drip irrigation devices have a relatively simple flow rate adjustment function, making it difficult to accurately adjust the flow rate according to the water requirements of pear trees at different growth stages and the amount of water evaporation under different weather conditions, resulting in water waste or insufficient irrigation. In terms of disassembly and maintenance, most existing drip irrigation devices use fixed connections for their components, making disassembly and maintenance operations complicated.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An adjustable flow rate drip irrigation device for pear trees includes a main pipe and branch pipes. A connecting pipe is movably sleeved inside the branch pipe. A limit ball is provided inside the connecting pipe. A connecting post is fixedly connected to the upper surface of the limit ball. A screw is provided at the upper end of the connecting pipe. Two sealing rings are fixedly connected to the annular side of the connecting pipe. A knob is fixedly connected to the upper surface of the screw.

[0012] Preferably, the upper surface of the connecting column is provided with a limiting groove, the limiting groove is rotatably connected to the screw, and the upper surface of the connecting pipe is provided with a threaded groove, the threaded groove is threadedly connected to the screw.

[0013] Preferably, the connecting pipe has two handles fixedly connected to its annular side, the branch pipe has a circular groove on its annular side, the connecting pipe is movably sleeved with the circular groove, the connecting pipe has a circular hole through its annular side, and the limiting ball is disposed in the circular hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Moving the connecting column will cause the fixed limiting ball to move as well. The upward movement of the limiting ball will increase the size of the round hole on the surface of the connecting pipe, and the flow rate will also increase. Conversely, turning the knob will decrease the flow rate. By precisely adjusting the flow rate, water can be supplied as needed according to the water requirements of pear trees at different growth stages and soil moisture conditions. This avoids the waste of water resources caused by excessive irrigation in traditional irrigation, and also prevents the growth of pear trees from being affected by insufficient water supply. This ensures that water resources are used fully and rationally, and improves the utilization rate of irrigation water.

[0016] 2. During installation, align the connecting pipe with the round groove and press down on the two handles. The two sealing rings will engage with the round groove to complete the installation. The detachable design of the connecting pipe facilitates thorough cleaning later, especially for impurities such as mud, scale, and algae that may accumulate inside the device after long-term use. This effectively removes impurities, preventing them from clogging the drippers or affecting the accuracy of flow regulation, thus ensuring the normal operation and irrigation effect of the drip irrigation system.

[0023] This application provides an adjustable flow rate drip irrigation device for pear trees, effectively solving the problem that most drip irrigation devices have a relatively simple flow rate adjustment function, making it difficult to accurately adjust the flow rate according to the water requirements of pear trees at different growth stages and the water evaporation rate under different weather conditions, resulting in water waste or insufficient irrigation. In terms of disassembly and maintenance, most existing drip irrigation devices use fixed connections, making disassembly and maintenance operations complicated. The adjustable flow rate function of this solution can control the irrigation water volume, improve water resource utilization efficiency, and promote pear tree growth. The detachable design facilitates the maintenance, cleaning, adjustment, transportation, and storage of the device, reduces operating costs, extends the service life of the equipment, and increases the flexibility of the system, providing a better solution for irrigation management of pear tree planting.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that most drip irrigation devices have a relatively simple flow regulation function, making it difficult to accurately adjust the flow according to the water requirements of pear trees at different growth stages and the water evaporation under different weather conditions, resulting in water waste or insufficient irrigation. Regarding detachable maintenance, existing drip irrigation devices mostly use fixed connections for their components, making disassembly and maintenance operations complex. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides an adjustable flow rate drip irrigation device for pear trees, including a main pipe 1 and a branch pipe 2. A connecting pipe 5 is movably sleeved inside the branch pipe 2. A limit ball 6 is installed inside the connecting pipe 5, and a connecting post 10 is fixedly connected to the upper surface of the limit ball 6. A screw 9 is installed at the upper end of the connecting pipe 5. Two sealing rings 8 are fixedly connected to the annular side of the connecting pipe 5. A knob 3 is fixedly connected to the upper surface of the screw 9. By adjusting the flow rate through the flow regulator in the main hub, the working pressure and flow rate of the system are set according to the water requirements of the pear trees. The water pump draws water from the water source, filters it, and then enters the main pipe 1. Under pressure, the water flows along the main pipe 1 and the branch pipe 2, and finally drips into the soil at the root of the pear trees through the drippers on the branch pipe 2. In this system, when the flow rate needs to be adjusted, turning the knob 3 counterclockwise causes the fixed screw 9 to rotate. The rotation of the screw 9 creates a threaded action with the connecting pipe 5, causing it to move upward. The movement of the screw 9 causes the connecting post 10 to move, which in turn causes the fixed limiting ball 6 to move. The upward movement of the limiting ball 6 increases the size of the hole 13 on the surface of the connecting pipe 5, thus increasing the flow rate. Conversely, turning the knob 3 counterclockwise decreases the flow rate. By precisely adjusting the flow rate, water can be supplied as needed based on the water requirements of the pear tree at different growth stages and the soil moisture. This avoids water waste caused by over-irrigation in traditional irrigation methods and prevents insufficient water supply from affecting the growth of the pear tree. This ensures that water resources are used fully and rationally, improving the utilization rate of irrigation water.

[0027] A limiting groove 12 is formed on the upper surface of the connecting column 10, and the limiting groove 12 is rotatably connected to the screw 9. A threaded groove 11 is formed on the upper surface of the connecting pipe 5, and the threaded groove 11 is threadedly connected to the screw 9. Two handles 4 are fixedly connected to the annular side of the connecting pipe 5. A circular groove 7 is formed on the annular side of the branch pipe 2, and the connecting pipe 5 is movably connected to the circular groove 7. A circular hole 13 is formed through the annular side of the connecting pipe 5, and a limiting ball 6 is set in the circular hole 13. When it is necessary to disassemble the connecting pipe 5, the two handles 4 fixed on the connecting pipe 5 are pulled to pull it out. The pull-out area of ​​the connector 4 is increased for easy removal. Two sealing rings 8 are provided on the connector 5 to ensure a tight seal. During installation, align the connector 5 with the circular groove 7 and press down on the two handles 4. The two sealing rings 8 will engage with the circular groove 7 to complete the installation. The detachable design of the connector 5 facilitates thorough cleaning, especially for impurities such as mud, scale, and algae that may accumulate inside the device after long-term use. This effectively removes impurities, preventing them from clogging the drippers or affecting the accuracy of flow regulation, thus ensuring the normal operation and irrigation effect of the drip irrigation system.

[0028] Among them, main pipe 1 is an important part of the drip irrigation device pipeline system. It is used to receive the water filtered by the head hub and transport it to branch pipe 2 to provide a water flow channel for subsequent irrigation.

[0029] Branch pipe 2: Connected to main pipe 1, it further transports the water in main pipe 1 to the vicinity of the pear tree roots. Drip nozzles are installed on it to directly supply water to the pear tree for drip irrigation.

[0030] Knob 3: Fixed on screw 9. By rotating knob 3, screw 9 is driven to rotate, thereby adjusting the position of limit ball 6 inside connecting pipe 5, and ultimately achieving the purpose of adjusting drip irrigation flow.

[0031] Handle 4: Fixed to the connecting tube 5, it facilitates the application of force when disassembling and installing the connecting tube 5, increases the gripping area during operation, and makes the insertion and removal of the connecting tube 5 more convenient.

[0032] Connecting pipe 5: It is movably sleeved inside the branch pipe 2. The water flow rate is adjusted by the internal limiting ball 6 cooperating with the surface round hole 13. It is also detachable for easy cleaning and maintenance.

[0033] Limiting ball 6: Set inside the connecting pipe 5, it moves up and down driven by the connecting column 10, thereby changing the size of the hole 13 on the surface of the connecting pipe 5, thus achieving precise adjustment of the drip irrigation flow rate;

[0034] Circular groove 7: It is opened on the annular side of the branch pipe 2 and is used to movably connect with the connecting pipe 5, providing an installation position for the connecting pipe 5 and ensuring the stability of the connection between the connecting pipe 5 and the branch pipe 2.

[0035] Sealing ring 8: Fixed on the annular side of the connecting pipe 5, it plays a sealing role when the connecting pipe 5 is connected to the branch pipe 2, preventing water leakage at the connection and ensuring the normal operation of the drip irrigation system;

[0036] Screw 9: It is threaded into the threaded groove 11 on the connecting pipe 5 and rotates under the action of knob 3. It moves up and down through the thread action, thereby driving the connecting column 10 and the limit ball 6 to move and adjust the flow rate.

[0037] Connecting column 10: One end is fixed to the limiting ball 6, and the other end is rotatably connected to the screw 9. When the screw 9 moves, it drives the limiting ball 6 to move, thereby adjusting the size of the hole 13.

[0038] Threaded groove 11: It is formed on the upper surface of the connecting pipe 5 and threadedly connected to the screw 9, so that the screw 9 can move up and down on the connecting pipe 5 when it rotates. It is a key part of the flow regulation structure.

[0039] Limiting groove 12: It is formed on the upper surface of the connecting column 10 and is rotatably connected to the screw 9. It can ensure that the connecting column 10 moves when the screw 9 rotates, and also limit the relative positional relationship between the two.

[0040] Circular hole 13: It is opened through the annular side of the connecting pipe 5. Its size is affected by the position of the limiting ball 6. The change in the pore size controls the water flow rate, thereby adjusting the drip irrigation flow rate.

[0041] Working principle:

[0042] The system's working pressure and flow rate are set according to the pear tree's water requirements via the flow regulator in the main hub. The water pump draws water from the source, filters it, and then it enters the main pipe 1. Under pressure, the water flows along the main pipe 1 and branch pipe 2, finally dripping into the soil around the pear tree roots through drippers on branch pipe 2. When the flow rate needs adjustment, turning knob 3 counterclockwise rotates the fixed screw 9. The screw 9 rotates and moves upward through the threaded connection with the connecting pipe 5. This movement of the screw 9 moves the connecting post 10, which in turn moves the fixed limit ball 6. The upward movement of the limit ball 6 increases the pore size of the circular hole 13 on the surface of the connecting pipe 5, thus increasing the flow rate. Conversely, turning knob 3 counterclockwise decreases the flow rate. By precisely adjusting the flow rate, water can be supplied as needed based on the pear tree's water requirements at different growth stages and soil moisture conditions. This design avoids water waste caused by excessive irrigation in traditional irrigation methods and prevents insufficient water supply from affecting pear tree growth, ensuring full and rational use of water resources and improving irrigation water utilization. When it is necessary to disassemble the connecting pipe 5, pull the two handles 4 fixed on the connecting pipe 5 to pull it out. The two handles 4 increase the pulling area, making it easier to pull out. The connecting pipe 5 is equipped with two sealing rings 8 to ensure sealing. During installation, align the connecting pipe 5 with the round groove 7 and press down on the two handles 4. The two sealing rings 8 will engage with the round groove 7 to complete the installation. The detachable design of the connecting pipe 5 facilitates comprehensive and thorough cleaning later, especially for impurities such as mud, scale, and algae that may accumulate inside the device after long-term use. It can effectively remove impurities to prevent them from clogging the drippers or affecting the accuracy of flow regulation, ensuring the normal operation and irrigation effect of the drip irrigation system.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
