Description

Technical Field

[0001] This application relates to the field of agricultural technology, and more specifically, to an adjustable drip irrigation device for agricultural irrigation. Background Technology

[0002] Drip irrigation is an irrigation method that delivers water or nutrients to the root zone of crops in a uniform and slow manner through a pipeline system and drippers installed on capillary tubes, according to the crop's water requirements. Drip irrigation does not disrupt soil structure, maintaining optimal water, fertilizer, air, and heat levels within the soil for crop growth. It minimizes evaporation loss, does not produce surface runoff, and has virtually no deep seepage, making it a water-saving irrigation method. Drip irrigation is typically implemented using drip irrigation devices that deliver water or nutrients directly to the plant's roots for easy absorption.

[0003] Currently, drip irrigation devices widely used in agricultural irrigation have obvious technical limitations: on the one hand, the length of their drip irrigation pipes is mostly fixed and cannot be flexibly adjusted and extended according to the actual planting area or crop layout, resulting in limited irrigation coverage and difficulty in adapting to the needs of fields of different sizes; on the other hand, existing devices generally lack the function of cleaning drip irrigation holes. During long-term use, scale, silt and algae can easily cause blockage of drip irrigation holes, which not only affects the uniformity of water output, but also significantly reduces irrigation efficiency and may even lead to local crop water shortage.

[0004] To address the aforementioned problems, this application provides an adjustable drip irrigation device for agricultural irrigation. Utility Model Content

[0005] One objective of this application is to provide an adjustable drip irrigation device for agricultural irrigation, comprising a drip irrigation pipe, with extension pipes slidably inserted into both ends of the drip irrigation pipe, a first drip irrigation hole and a second drip irrigation hole respectively opened on the outer side of the drip irrigation pipe and the extension pipe, a circular tube symmetrically fixedly connected to the inner wall of the extension pipe, a spring installed inside the circular tube, a connecting column slidably connected inside the circular tube, a horizontal plate fixedly connected to the top of the connecting column, a vertical rod rotatably connected to the top of the horizontal plate, the top of the vertical rod penetrating the drip irrigation pipe and extending to the outer side of the drip irrigation pipe, a carrying rod fixedly connected to the top of the vertical rod, a fixing rod fixedly connected to both ends of the drip irrigation pipe and disposed on the outer side of the extension pipe, a slot opened at the top of the fixing rod, an insert rod inserted into the slot, a connecting rod fixedly connected to the bottom end of the horizontal plate, and a dredging rod fixedly connected to the bottom end of the connecting rod.

[0006] Furthermore, one end of the spring is fixedly connected to the inner wall of the extension tube, and the other end of the spring is fixedly connected to the connecting post.

[0007] Furthermore, a sliding groove is provided on the inner wall of the circular tube, and a sliding block is slidably connected inside the sliding groove. The sliding block is fixedly connected to the outer side of the connecting column.

[0008] Furthermore, the inner wall of the fixing rod is provided with a sliding groove, and a sliding plate is slidably connected inside the sliding groove. The sliding plate is fixedly connected to the outer side of the extension tube.

[0009] Furthermore, the top end of the insertion rod is fixedly connected to the handle, and the lower end of the unblocking rod is configured with a conical shape.

[0010] Furthermore, multiple slots are provided, and the spacing between two adjacent slots is equal. The extension tube has a through hole, and the upright passes through the through hole.

[0011] The beneficial effects of this application are:

[0012] 1. The device adopts a telescopic extension tube design, which allows for flexible adjustment of the drip irrigation length through a simple lifting operation. The irrigation range can be freely adjusted according to different field areas and crop layout requirements, effectively solving the problem of poor adaptability of traditional fixed-length drip irrigation tubes and significantly improving the applicability and practicality of the device.

[0013] 2. It uniquely integrates the drip irrigation hole unblocking function. By rotating and pressing the handle, the unblocking rod can be driven to clean all drip irrigation holes simultaneously, which completely solves the clogging problem caused by scale and silt accumulation in traditional devices, ensuring the uniformity and stability of irrigation and greatly reducing the difficulty of maintenance.

[0014] In summary, the overall structural design is ingenious and reasonable, perfectly integrating length adjustment and dredging and maintenance functions. All function switching can be completed with a simple operation of the handle, greatly simplifying the operation process and improving the efficiency of use. Attached Figure Description

[0028] Example:

[0029] Please see Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 and Figure 6 This application discloses an adjustable drip irrigation device for agricultural irrigation, including a drip irrigation pipe 1. A connecting pipe is fixedly connected to the middle of the outer side of the drip irrigation pipe 1, and the connecting pipe is connected to an external water source. Water entering the drip irrigation pipe 1 and the extension pipe 2 is discharged from the first drip irrigation hole 101 and the second drip irrigation hole 201 to irrigate crops. Extension pipes 2 are slidably inserted into both ends of the drip irrigation pipe 1. The outer sides of the drip irrigation pipe 1 and the extension pipe 2 are respectively provided with the first drip irrigation hole 101 and the second drip irrigation hole 201. The diameters of the first drip irrigation hole 101 and the second drip irrigation hole 201 are... Equal in size, the inner wall of the extension tube 2 is symmetrically fixed with round tubes 16. A spring 13 is installed inside the round tube 16. A connecting post 11 is slidably connected inside the round tube 16. A horizontal plate 8 is fixedly connected to the top of the connecting post 11. A vertical rod 6 is rotatably connected to the top of the horizontal plate 8. The bottom end of the vertical rod 6 is rotatably connected to the top surface of the horizontal plate 8 via a bearing. The top of the vertical rod 6 penetrates the drip irrigation tube 1 and extends to the outside of the drip irrigation tube 1. A carrying rod 4 is fixedly connected to the top of the vertical rod 6. Both ends of the drip irrigation tube 1 are fixedly connected to fixing rods 3 located on the outside of the extension tube 2. A slot 7 is provided at the top of the fixed rod 3, and a rod 5 is inserted into the slot 7. A connecting rod 10 is fixedly connected to the bottom end of the horizontal plate 8, and a drain rod 9 is fixedly connected to the bottom end of the connecting rod 10. This causes the handle 4 to move upward, which in turn causes the rod 5 to move upward, thus allowing the rod 5 to move out of the slot 7 to release the restriction on the extension tube 2. When the handle 4 moves upward, it causes the upright rod 6 to move upward, which in turn causes the horizontal plate 8 and the connecting column 11 to move upward. When the connecting column 11 moves upward inside the round tube 16, it springs... When the spring 13 is stretched, it causes the handle 4 to move away from the drip irrigation tube 1, thereby causing the extension tube 2 to move through the slide plate 12 inside the slide groove 31, thus extending the length of the main drip irrigation tube and improving the applicability of the device. After the extension adjustment is completed, the handle 4 is released. At this time, the spring 13 returns to its original position, causing the horizontal plate 8 to move back to its original position, thereby allowing the insertion rod 5 to be inserted into the corresponding slot 7, thus limiting and fixing the adjusted extension tube 2. At this time, the first drip irrigation hole 101 corresponds exactly to the second drip irrigation hole 201.

[0030] When it is necessary to unclog and clean the first drip irrigation hole 101 and the second drip irrigation hole 201, the extension tube 2 is moved inside the drip irrigation tube 1, causing the upright rod 6 to move to a state of contact with the end of the drip irrigation tube 1. At this time, all the first drip irrigation holes 101 and the second drip irrigation holes 201 are aligned with the unclogging rod 9. Then, the handle 4 is moved upward to allow the insertion rod 5 to move out of the slot 7. Then, the handle 4 is rotated, which in turn causes the upright rod 6 and the insertion rod 5 to rotate, thereby rotating the handle 4 to a state parallel to the drip irrigation tube 1. The insertion rod 5 rotates. Move the rod to one side of the fixed rod 3 so that there is a certain distance between the bottom end of the insertion rod 5 and the outer wall of the drip irrigation pipe 1 to allow the insertion rod 5 to move downward. Then press the handle 4 to move downward. The downward movement of the handle 4 drives the insertion rod 5, the upright rod 6 and the horizontal plate 8 to move downward. The downward movement of the horizontal plate 8 drives the connecting rod 10 and the unblocking rod 9 to move downward to unblock and clean the second drip irrigation hole 201 and the first drip irrigation hole 101. When the horizontal plate 8 moves downward, the horizontal plate 8 drives the connecting column 11 to move downward to compress the spring 13. The spring 13 is compressed and contracts.

[0031] Please see Figure 3 One end of the spring 13 is fixedly connected to the inner wall of the extension tube 2, and the other end of the spring 13 is fixedly connected to the connecting post 11. The inner wall of the round tube 16 is provided with a sliding groove 15. A sliding block 14 is slidably connected inside the sliding groove 15. The sliding block 14 is fixedly connected to the outer side of the connecting post 11. The cooperation between the sliding block 14 and the sliding groove 15 limits the sliding of the connecting post 11. When the connecting post 11 moves, it guides the movement of the connecting post 11. When the connecting post 11 moves, it drives the sliding block 14 to move inside the sliding groove 15, which improves the stability of the connecting post 11 when it moves.

[0032] Please see Figure 5 The inner wall of the fixed rod 3 is provided with a sliding groove 31, and a sliding plate 12 is slidably connected inside the sliding groove 31. The cooperation between the sliding plate 12 and the sliding groove 31 limits the sliding of the extension tube 2. When the extension tube 2 moves, the extension tube 2 drives the sliding plate 12 to move inside the sliding groove 31, thereby improving the stability of the extension tube 2 when it moves. The sliding plate 12 is fixedly connected to the outer side of the extension tube 2. The top of the insertion rod 5 is fixedly connected to the carrying plate. The lower end of the unblocking rod 9 is set with a conical structure. There are multiple slots 7, and the spacing between two adjacent slots 7 is equal. A through hole is opened on the extension tube 2, and the upright rod 6 passes through the through hole.

[0033] The implementation principle of this application embodiment is as follows:

[0034] The connecting pipe fixedly connected to the middle of the outer side of the drip irrigation pipe 1 is connected to an external water source. Water that enters the drip irrigation pipe 1 and the extension pipe 2 is discharged from the first drip irrigation hole 101 and the second drip irrigation hole 201 to irrigate the crops.

[0035] The handle 4 is moved upward, which in turn moves the insert rod 5 upward, causing the insert rod 5 to move out of the slot 7 to release the restriction on the extension tube 2. When the handle 4 moves upward, the upright rod 6 moves upward, which in turn moves the horizontal plate 8 and the connecting column 11 upward. When the connecting column 11 moves upward inside the round tube 16, the spring 13 is stretched, which causes the handle 4 to move away from the drip irrigation tube 1, thereby causing the extension tube 2 to move through the slide plate 12 inside the slide groove 31, thereby extending the length of the drip irrigation tube and improving the applicability of the device. After the extension adjustment is completed, the handle 4 is released. At this time, the spring 13 returns to its original position, causing the horizontal plate 8 to move back to its original position, so that the insert rod 5 can be inserted into the corresponding slot 7, thereby limiting and fixing the adjusted extension tube 2. At this time, the first drip irrigation hole 101 corresponds to the second drip irrigation hole 201.

[0036] When it is necessary to unclog and clean the first drip irrigation hole 101 and the second drip irrigation hole 201, the extension tube 2 is moved inside the drip irrigation tube 1, causing the upright 6 to move to a state of contact with the end of the drip irrigation tube 1 (i.e., as shown in the attached diagram of the instruction manual). Figure 2 (Illustrated state) At this time, all the first drip irrigation holes 101 and the second drip irrigation holes 201 are aligned with the unblocking rod 9. Then, the handle 4 is moved upward so that the insertion rod 5 is moved out of the slot 7. Then, the handle 4 is rotated, which in turn drives the upright rod 6 and the insertion rod 5 to rotate, thereby rotating the handle 4 to a state parallel to the drip irrigation tube 1. The insertion rod 5 is rotated to one side of the fixed rod 3 so that there is a certain distance between the bottom end of the insertion rod 5 and the outer wall of the drip irrigation tube 1 for the insertion rod 5 to move downward. Then, the handle 4 is pressed down to move downward. The downward movement of the handle 4 drives the insertion rod 5, the upright rod 6 and the horizontal plate 8 to move downward. The downward movement of the horizontal plate 8 drives the connecting rod 10 and the unblocking rod 9 to move downward to unblock and clean the second drip irrigation hole 201 and the first drip irrigation hole 101.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
