Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a water spraying device for agricultural irrigation. Background Technology
[0002] Agricultural irrigation refers to the engineering and management activities of introducing water resources (such as river water, lake water, groundwater, or reclaimed water) into farmland through artificial means to supplement insufficient natural rainfall and meet the water needs of crop growth. Existing irrigation methods mostly involve pumping water directly into the farmland or evenly spreading it through equipment. To achieve more even spreading without interfering with tilling or harvesting, underground automatic riser irrigation systems are used. This achieves uniform irrigation without affecting the use of large agricultural machinery. However, when encountering compacted or hardened soil, it is necessary to loosen the soil first, or use higher water pressure. Furthermore, the area around the water outlet is often covered with sand or plastic anti-clogging covers to prevent soil accumulation, making it cumbersome to use. Therefore, an agricultural irrigation sprinkler system is designed to solve these problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: an agricultural irrigation sprinkler device, comprising: a hollow main pipe 1 with an open upper end, one end of the main pipe 1 connected to a water pump, a bottom sleeve 2 connected to the upper end of the main pipe 1 via a flange, a middle sleeve 3 slidably connected to the middle of the bottom sleeve 2, a water outlet pipe 4 slidably connected to the middle of the middle sleeve 3, a limit plate 5 connected to the lower end of both the middle sleeve 3 and the water outlet pipe 4, a sealing ring sleeved on the outer side of the limit plate 5, and a nozzle 6 rotatably connected to the upper end of the water outlet pipe 4. The interior of the nozzle 6 is connected to the interior of the water outlet pipe 4. A high-pressure nozzle is installed inside the nozzle 6, and the water outlet end of the high-pressure nozzle extends to the outside of the nozzle 6. The upper end of the nozzle 6 is conical, and a spiral blade 7 is fixedly connected to the outer side of the upper conical end of the nozzle 6. A spiral push rod 8 is fixedly connected to the upper end inside the nozzle 6, and the lower end of the spiral push rod 8 extends to the interior of the water outlet pipe 4. A return spring 9 is connected to the upper end of the bottom sleeve 2 and the outer side of the lower end of the middle sleeve 3, and the upper end of the middle sleeve 3 and the outer side of the lower end of the water outlet pipe 4.
[0025] When in use, the agricultural irrigation sprinkler device is pre-buried in the farmland. When irrigation is needed, the water pump is turned on, and the water pump draws water into the main pipe 1. The increased internal water pressure pushes the intermediate sleeve 3 and the outlet pipe 4 upward together. As the water flows outward, the spiral push rod 8 inside the outlet pipe 4 is spiral-shaped and rotates under the drive of the water flow, thereby driving the nozzle 6 to rotate as well. The upper end of the nozzle 6 is conical and has spiral blades 7 on the outside. At this time, the nozzle 6 can act as a ground drill, loosening and breaking some soil layers that are not easy to push out, so that the intermediate sleeve 3 and the outlet pipe 4 can extend out and spray water through the high-pressure nozzle installed inside the nozzle 6. The nozzle 6 also rotates while spraying water, making the spraying more even. After the spraying is completed, the water pump is turned off, the internal water pressure decreases, and the return spring 9 will pull the intermediate sleeve 3 and the outlet pipe 4 back to their original positions.
[0026] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the bottom sleeve 2 and the middle sleeve 3 are both fixedly connected with guide rails 21 around their inner circumference, and the limiting plate 5 is slidably connected to the guide rails 21.
[0027] Analysis of the above structure shows that the guide rail 21 can play a guiding role and prevent the intermediate sleeve 3 and the outlet pipe 4 from deviating from their extended positions.
[0028] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the upper ends of the bottom sleeve 2 and the middle sleeve 3 are both inserted and connected with spring limiting plates 22. The inner wall of the spring limiting plate 22 is connected with a sealing ring. The outer sides of the upper ends of the bottom sleeve 2 and the middle sleeve 3 are both connected with end caps 23 by threads.
[0029] Analysis of the above structure shows that the spring limiting plate 22 restricts the position of the upper end of the reset spring 9. When cleaning, inspection and maintenance are required, the lower end cover 23 can be rotated directly for disassembly.
[0030] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the upper side of the end cap 23 at the upper end of the intermediate sleeve 3 is also conical.
[0031] Analysis of the above structure shows that the upper side of the end cap 23 at the upper end of the intermediate sleeve 3 is also conical, which can reduce the resistance when the intermediate sleeve 3 is lifted upward.
[0032] like Figure 1-5As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the interior of the water outlet pipe 4 is conical with a wider bottom and a narrower top. The lower end of the spiral push rod 8 is rotatably connected to the interior of the water outlet pipe 4. The outer side of the upper end of the spiral push rod 8 is provided with a gap of one millimeter from the upper opening of the water outlet pipe 4.
[0033] Analysis of the above structure shows that the conical shape of the water outlet pipe 4, which is wider at the bottom and narrower at the top, allows for a greater flow velocity and water pressure at the top, thus better driving the spiral push rod 8. The lower end of the spiral push rod 8 is rotatably connected to the inside of the water outlet pipe 4, which makes the spiral push rod 8 more stable.
[0034] like Figure 1-5 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the main pipe 1, bottom sleeve 2, middle sleeve 3, and outlet pipe 4 are all made of PE material, and the nozzle 6 and spiral push rod 8 are all made of stainless steel.
[0035] Analysis of the above structure shows that the main pipe 1, bottom sleeve 2, intermediate sleeve 3, and outlet pipe 4 are made of PE material, which has better corrosion resistance and a certain degree of rigidity, so they will not be damaged. The nozzle 6 and the spiral push rod 8 are made of stainless steel, which can reduce damage caused by corrosion.
[0036] like Figure 1-2 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the lower end of the intermediate sleeve 3 and the water outlet pipe 4 are stepped when retracted.
[0037] Analysis of the above structure shows that when the middle sleeve 3 and the outlet pipe 4 are retracted, the lower end is stepped, which guides the water flow in the initial stage of water injection.
