[0003] A drip irrigation type composite PE pipe is a pipe system used for agricultural irrigation. It combines the advantages of drip irrigation technology and PE (polyethylene) pipes. Through drip irrigation technology, the drip irrigation type composite PE pipe can significantly improve the utilization rate of water and reduce water loss during irrigation.

[0004] In the prior art, when using drip irrigation type composite PE pipe fittings, they are usually connected by hot melting or electrofusion. Hot melting connection requires heating the connection parts of pipes or pipe fittings to a molten state, then quickly fitting and cooling. This process takes a certain amount of time. Especially in the connection of large-diameter pipes, the heating and cooling time will be longer, thus affecting the connection speed and slow installation. At the same time, hot melting connection requires operators to have high professional skills and experience to ensure the welding quality. If the operator's skills are insufficient or the operation is improper, it may lead to problems such as welding failure or pipe leakage, which will not only affect the installation efficiency but also increase the later maintenance cost. Therefore, a drip irrigation type composite PE pipe for agricultural irrigation is proposed to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Such as Figures 1-4As shown in the figure, a drip irrigation type composite PE pipe for agricultural irrigation includes a drip irrigation pipe 1; a first connecting pipe 2 and a connecting inner pipe 3 are installed on the drip irrigation pipe 1; a sliding pipe 9 is slidably connected to the connecting inner pipe 3; a rotating pipe 6 is connected to the sliding pipe 9; the rotating pipe 6 is slidably connected to the drip irrigation pipe 1; three drive shafts 8 are rotatably connected to the sliding pipe 9; a first gear 7 is installed at the left end of the drive shaft 8; the three first gears 7 are meshed and connected to the inside of the same rotating pipe 6; a threaded rod 10 is installed at the right end of the drive shaft 8; three positioning grooves 4 and threaded grooves 5 are formed in the first connecting pipe 2; three positioning blocks 11 are installed on the sliding pipe 9, and the drive shaft 8 is rotatably connected to the positioning block 11; a clamping groove 14 is formed in the first connecting pipe 2; a sealing ring 15 is installed on the connecting inner pipe 3; during operation, by inserting the three positioning blocks 11 on the sliding pipe 9 into the positioning grooves 4 on the first connecting pipe 2, the connecting inner pipe 3 is clamped in the clamping groove 14, and then the rotating pipe 6 is rotated. A gear groove meshed with the first gear 7 is formed in the rotating pipe 6, so that the rotating pipe 6 drives the three first gears 7 to rotate. Furthermore, the first gear 7 drives the drive shaft 8 to rotate. The drive shaft 8 rotates on the sliding pipe 9, and then drives the threaded rod 10 connected thereto to rotate, so that the threaded rod 10 rotates into the threaded groove 5 threadedly connected thereto, and then the sliding pipe 9 drives the rotating pipe 6 to slide on the connecting inner pipe 3. Thus, the threaded rod 10 is threadedly connected to the threaded groove 5 on the connecting pipe, and then the pipeline connection is completed for installation;

[0024] Through the cooperation of the rotating pipe 6 and the drive shaft 8, and the threaded connection between the threaded rod 10 and the threaded groove 5, the rapid installation between the drip irrigation pipes 1 is realized. The operator only needs to simply insert the positioning block 11 into the positioning groove 4 and rotate the rotating pipe 6, then the threaded rod 10 can be automatically screwed into the threaded groove 5 to complete the connection. Similarly, during disassembly, only by rotating the rotating pipe 6 in the reverse direction, the pipeline can be easily separated, greatly improving the installation and disassembly efficiency;

[0025] The meshing design of the first gear 7 and the gear groove in the connection structure ensures that the rotating pipe 6 can drive the three drive shafts 8 to rotate synchronously during the rotation process, so that the threaded rod 10 is evenly and stably screwed into the threaded groove 5, reducing the connection looseness or damage caused by uneven force. At the same time, the installation of the sealing ring 15 further enhances the connection tightness, reducing the waste and leakage of water resources.

[0026] Furthermore, as Figure 4As shown in the figure, a filter screen 23 and a support frame 20 are installed inside the drip irrigation pipe 1; the support frame 20 is arranged on the right side of the filter screen 23; a connecting shaft 22 is rotatably connected to the support frame 20; a turbine blade 21 is installed on the connecting shaft 22; the turbine blade 21 is arranged on the right side of the filter screen 23; one end of the left side of the connecting shaft 22 is rotatably connected to the filter screen 23; three scraping plates 25 are installed at one end of the left side of the connecting shaft 22 passing through the filter screen 23, and the three scraping plates 25 overlap on the same filter screen 23; during operation, the function of the filter screen 23 is to filter the water required for drip irrigation, remove impurities and particulate matters therein, reduce the blockage of drip irrigation holes by these impurities, and ensure the smooth operation of the drip irrigation system, which is of great significance for improving irrigation efficiency and protecting the crop roots from impurities; the turbine blade 21 utilizes the water flow power inside the drip irrigation pipe 1. When the water flow passes through, it will drive the turbine blade 21 to rotate, and then drive the scraping plate 25 to rotate through the connecting shaft 22. During the rotation process of the scraping plate 25, it will continuously scrape the surface of the filter screen 23 to remove the impurities and particulate matters attached to it, realizing the automatic cleaning function. This automatic cleaning mechanism can significantly reduce the frequency and difficulty of manual cleaning and extend the service life of the filter screen 23.

[0027] Further, as Figure 1 shown, two mounting brackets 16 are symmetrically installed on the connecting pipe; a buckle 18 is rotatably connected to the mounting bracket 16; a torsion spring 17 is installed at the connection end of the buckle 18 and the mounting bracket 16; two card slots 19 are symmetrically opened on the sliding pipe 9; the buckle 18 and the card slot 19 are used in cooperation and are clamped with each other; during operation, the threaded rod 10 on the sliding pipe 9 is installed in the threaded groove 5 inside the connecting pipe 2. After fixation, at the same time, the buckle 18 is opened so that the buckle 18 is clamped in the card slot 19, and the torsion spring 17 uses its elastic characteristic to make the buckle 18 firmly clamped in the card slot 19; the cooperation between the buckle 18 and the card slot 19, as well as the elastic action of the torsion spring 17, enable the connecting pipes to be more firmly combined together after fixation. This double locking mechanism effectively reduces the loosening or falling off of the connection caused by external factors such as vibration and water flow impact, thus ensuring the stable operation of the drip irrigation system.

[0028] Further, as Figure 2 shown, a guiding sliding groove 13 is opened on the connecting inner pipe 3; a sliding block 12 is slidably connected in the guiding sliding groove 13, and the sliding block 12 is fixed on the sliding pipe 9; during operation, while the sliding pipe 9 slides, it drives the connected sliding block 12 to slide in the guiding sliding groove 13; the guiding sliding groove 13 provides a clear sliding path for the sliding block 12, enabling the sliding pipe 9 to remain stable and not shake during the sliding process, and reducing the offset when the threaded rod 10 is connected to the threaded groove 5.

[0029] Further, as Figure 1As shown, a fixing ring 26 is installed on the drip irrigation pipe 1; a fixing screw 27 is threadedly connected to the fixing ring 26; a rotary plug-in member 28 is installed at the bottom of the fixing screw 27; during operation, a rotary handle is installed at the top of the fixing screw 27; by rotating the rotary handle, the rotary handle drives the fixing screw 27 to rotate on the fixing ring 26 threadedly connected thereto, so that the fixing screw 27 drives the spiral plug-in member to insert into the soil, thereby fixing the drip irrigation pipe 1 and making the drip irrigation pipe 1 more stable during use.

[0030] Working principle: During operation, three positioning blocks 11 on the sliding pipe 9 are inserted into the positioning slots 4 on the first connecting pipe 2, so that the connecting inner pipe 3 is clamped in the clamping slot 14. Then, the rotating pipe 6 is rotated. A gear slot meshing with the first gear 7 is provided in the rotating pipe 6, so that the rotating pipe 6 drives the three first gears 7 to rotate. Further, the first gears 7 drive the drive shaft 8 to rotate. The drive shaft 8 rotates on the sliding pipe 9, and then drives the threaded rod 10 connected thereto to rotate, so that the threaded rod 10 rotates into the threaded slot 5 threadedly connected thereto. Further, the sliding pipe 9 drives the rotating pipe 6 to slide on the connecting inner pipe 3, so that the threaded rod 10 is threadedly connected in the threaded slot 5 on the connecting pipe, and then the pipeline connection is completed for installation; Through the cooperation of the rotating pipe 6 and the drive shaft 8, and the threaded connection between the threaded rod 10 and the threaded slot 5, the rapid installation of the drip irrigation pipes 1 is realized. The operator only needs to simply insert the positioning block 11 into the positioning slot 4 and rotate the rotating pipe 6, then the threaded rod 10 can be automatically screwed into the threaded slot 5 to complete the connection. Similarly, during disassembly, only the rotating pipe 6 needs to be rotated in the reverse direction, and the pipeline can be easily separated, greatly improving the installation and disassembly efficiency; The meshing design of the first gears 7 and the gear slot in the connection structure ensures that the rotating pipe 6 can drive the three drive shafts 8 to rotate synchronously during rotation, and then the threaded rod 10 is evenly and stably screwed into the threaded slot 5, reducing connection looseness or damage caused by uneven stress. At the same time, the installation of the sealing ring 15 further enhances the connection tightness, reducing water resource waste and leakage; During operation, the function of the filter screen 23 is to filter the water required for drip irrigation, remove impurities and particulate matters therein, reduce the blockage of these impurities in the drip irrigation holes, and ensure the smooth operation of the drip irrigation system, which is of great significance for improving irrigation efficiency and protecting the crop roots from impurity damage; The turbine blades 21 utilize the water flow power inside the drip irrigation pipe 1. When the water flow passes through, it will drive the turbine blades 21 to rotate. Further, the scraper 25 is driven to rotate through the connecting shaft 22. During the rotation of the scraper 25, it will continuously scrape the surface of the filter screen 23 to remove the impurities and particulate matters attached thereto, realizing the automatic cleaning function. This automatic cleaning mechanism can significantly reduce the frequency and difficulty of manual cleaning and extend the service life of the filter screen 23; During operation, the threaded rod 10 on the sliding pipe 9 is installed in the threaded slot 5 in the first connecting pipe 2 and fixed. At the same time, the buckle 18 is opened, so that the buckle 18 is clamped in the slot 19. The torsion spring 17 makes the buckle 18 firmly clamped in the slot 19 by virtue of its elastic characteristics; The cooperation between the buckle 18 and the slot 19, and the elastic action of the torsion spring 17 enable the connecting pipes to be more firmly combined together after being fixed. This double locking mechanism effectively reduces connection looseness or detachment caused by external factors such as vibration and water flow impact, thus ensuring the stable operation of the drip irrigation system.
