Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation equipment technology, specifically a detachable and automatically retractable sprinkler irrigation extension rod. Background Technology

[0002] The buried telescopic sprinkler system is buried below the topsoil layer and does not affect farming. It integrates the ground pipe, vertical pipe, and lifting sprinkler head into one unit, and has both water spraying and top-out functions.

[0003] The existing underground telescopic sprinkler irrigation equipment on the market has the following technical defects:

[0004] 1. Currently available underground telescopic sprinkler irrigation equipment extends 0.8 meters above the ground, which can meet the irrigation needs of low-stalk crops, but cannot meet the irrigation needs of high-stalk crops over 2 meters tall, such as corn and sorghum.

[0005] 2. The automatic retraction product of the buried telescopic sprinkler irrigation equipment needs to automatically retract into the ground. The extension rod generally cannot retract into the ground with the telescopic pipe.

[0006] 3. The biggest factor affecting sprinkler irrigation is the wind force. When irrigation equipment with extended poles is used in strong winds, it will affect the irrigation effect, the uniformity of irrigation, and the range of the water jet. Utility Model Content

[0007] The purpose of this invention is to provide a detachable, automatically retractable sprinkler extension rod.

[0008] A detachable, automatically retractable sprinkler extension rod includes an extension sprinkler rod with an inlet and an outlet at its bottom and top, respectively. A limit device is fixedly installed at the bottom of the extension sprinkler rod, and a lifting device that cooperates with the limit device is movably installed on the outside of the extension sprinkler rod.

[0009] Furthermore, the limiting device includes a fixing seat, and the bottom of the extended sprinkler rod is fixedly provided with a fixing seat.

[0010] Furthermore, the lifting device includes an externally threaded slide block slidably disposed outside the extended sprinkler rod, and a spring is disposed between the externally threaded slide block and the fixed seat, the spring being sleeved on the outside of the extended sprinkler rod.

[0011] Furthermore, the fixed base is provided with multiple sealing rings on its exterior.

[0012] Furthermore, the water outlet is provided with a nozzle connection thread.

[0013] In summary, this utility model has the following beneficial effects:

[0014] This invention increases the underground height of existing underground telescopic sprinkler irrigation equipment by over 100%, meeting the irrigation needs of different crops. Utilizing the elastic deformation of a spring, the extended sprinkler rod is retracted and stored inside the inner tube, ensuring the extended sprinkler rod returns to a safe position without increasing the original height of the underground telescopic sprinkler irrigation equipment, preventing damage from other machinery. For irrigating low-stalk crops, where excessive height of the irrigation equipment is unnecessary and reduces wind resistance, the extended rod can be disassembled, restoring the original height or shape of the underground sprinkler irrigation equipment to meet the irrigation needs of low-stalk crops.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described as follows:

[0022] A detachable and automatically retractable sprinkler extension rod includes an extension sprinkler rod 1, with an inlet 2 and an outlet 3 respectively provided at the bottom and top of the extension sprinkler rod 1. A limit device is fixedly provided at the bottom of the extension sprinkler rod 1, and a lifting device that cooperates with the limit device is movably provided on the outside of the extension sprinkler rod 1.

[0023] Chinese Patent Application No. 202520969926.5 discloses a "water-driven self-relief buried telescopic sprinkler irrigation device". An inner tube is slidably disposed within an outer tube assembly. A nozzle and a sliding seat are fixedly installed at the upper and lower ends of the inner tube, respectively. Preferably, the nozzle is fixedly connected to the inner tube via a nozzle fixing seat. The sliding seat divides the interior of the outer tube assembly into an inner cavity one and an inner cavity two. The outer tube assembly includes an outer tube, with an upper water inlet seat and a lower water inlet seat fixedly installed at its upper and lower ends, respectively. The inner tube is slidably connected to the upper water inlet seat, and the sliding seat is slidably connected to the interior of the outer tube, dividing the interior of the outer tube into an inner cavity one and an inner cavity two. The upper and lower water inlet seats communicate with the inner cavity one and inner cavity two, respectively. The nozzle extends to the outside of the outer tube assembly. An upper cover is fixedly installed on the upper water inlet seat, and the upper cover is slidably connected to the inner tube. A water inlet bracket seat that cooperates with the sliding seat is fixedly installed inside the upper water inlet seat. A fixed sliding seat is fixedly installed inside the water inlet bracket seat, and the fixed sliding seat is slidably connected to the inner tube. A self-relief assembly is slidably installed inside the sliding seat. This assembly includes a spring-mounted fixing seat fixedly installed on the lower side of the sliding seat and a spring-mounted slide seat slidably installed on the upper side of the sliding seat. A spring is installed between the spring-mounted fixing seat and the spring-mounted slide seat. Multiple connection holes are provided on the sliding seat to mate with the self-relief assembly, and the spring-mounted slide seat mates with these connection holes. By dividing the sliding seat into inner cavities one and two, water is output from these cavities respectively, changing the direction of the internal water pressure. This allows the nozzle to extend and retract, overcoming soil friction and ensuring it retracts to a safe position, preventing damage from other machinery during cultivation. The nozzles irrigate by spraying water droplets, achieving high flow rates and long range. This reduces irrigation time, increases efficiency, and lowers labor and material consumption without harming crops at different stages. The self-relief assembly ensures drainage in the return water pipe, protecting the expansion joint from high pressure damage. It can replace the return water pipe control valve, reducing project costs and system failure rate.

[0024] The inner tube of this patent has a limited length, generally extending 0.8 meters above the ground. This is sufficient to meet the irrigation needs of short-stalked crops, but it cannot meet the irrigation needs of tall crops that are more than 2 meters tall, such as corn and sorghum.

[0025] In this embodiment, for irrigation of tall crops, the nozzle of this patent is removed and installed on top of the outlet 3. The extended sprinkler rod 1 is placed inside the inner tube and slidably connected to it. Preferably, the outlet 3 is provided with a nozzle connection thread 8, and the nozzle is threadedly connected to the nozzle connection thread 8. When water is supplied to the inner tube, the water flow enters the extended sprinkler rod 1 from the inlet 2. The water pressure pushes the extended sprinkler rod 1 upward along the inner tube and extends it out of the inner tube. At this time, the lifting device is compressed. The combination of the extended sprinkler rod 1 and the inner tube makes the nozzle position higher, which can meet the irrigation needs of tall crops such as corn and sorghum. When the water flow stops, the water pressure decreases until it disappears, and the elasticity of the lifting device itself returns it to its original state, storing the extended sprinkler rod 1 back into the inner tube.

[0026] The limiting device includes a fixed base 4, and the bottom of the extended sprinkler rod 1 is fixedly provided with a fixed base 4.

[0027] In this embodiment, the fixing seat 4 slides inside the inner tube and is slidably connected to the inner tube. The fixing seat 4 activates to limit the bottom of the lifting device, and the fixing seat 4 increases the contact area between the water flow and the bottom of the extended sprinkler rod 1, making it easier for the water flow and water pressure to lift the extended sprinkler rod 1. Preferably, the fixing seat 4 is provided with multiple sealing rings 5 ​​on its exterior to prevent water from flowing out from the gap between the fixing seat 4 and the inner tube, thus reducing the water pressure.

[0028] The lifting device includes an externally threaded slide block 6 that is slidably disposed outside the extended sprinkler rod 1, and a spring 7 is disposed between the externally threaded slide block 6 and the fixed seat 4. The spring 7 is sleeved on the outside of the extended sprinkler rod 1.

[0029] In this embodiment, when the water pressure pushes the extended sprinkler rod 1 upward along the inner tube and extends it out of the inner tube, the fixing seat 4 moves upward along the inner wall of the inner tube, the distance between the fixing seat 4 and the external threaded slide 6 decreases, and the spring 7 is compressed. The extended sprinkler rod 1 extends upward and combines with the inner tube, making the nozzle position higher, which can meet the irrigation needs of tall crops such as corn and sorghum. When the water flow stops, the water pressure decreases until it disappears, the spring 7 extends and returns to its original shape, and the spring 7 drives the fixing seat 4 and the extended sprinkler rod 1 to move downward, so that they are housed in the inner tube. In summary, this utility model is not limited to the specific embodiments described above. Those skilled in the art can make several modifications and alterations without departing from the spirit and scope of this utility model. The protection scope of this utility model should be determined by the claims of this utility model.
