[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5An adjustable agricultural irrigation device includes a base 1, with a water supply pipe 11 fixed inside the base 1. The water supply pipe 11 has an L-shaped structure, with one end horizontally passing through the side wall of the base 1 and leading out. The water supply pipe 11 leading out from the side wall of the base 1 can be directly connected to an external water source pipe or water pump to ensure the stability of the water supply process. The other end passes through the upper end of the base 1 and leads out upward.

[0028] A transition pipe 12 is inserted into the upper end of the water supply pipe 11, and a transition pipe 2 13 is inserted into the upper end of the transition pipe 12. A distal spray pipe 14 is fixedly inserted through the transition pipe 2 13 near its upper end, and a distal nozzle 15 is fixedly connected to the end of the distal spray pipe 14. The distal spray pipe 14, together with the distal nozzle 15, can spray water to irrigate the distal area centered on the base 1. A proximal spray pipe 16 is fixedly inserted through the transition pipe 2 13 near its lower end, and a proximal nozzle 17 is fixedly connected to the end of the proximal spray pipe 16. The proximal spray pipe 16, together with the proximal nozzle 17, can spray water to irrigate the proximal area centered on the base 1. Two sets of both the distal spray pipe 14 and the proximal spray pipe 16 are provided and are symmetrically distributed along the surface of the transition pipe 2 13.

[0029] The lower end of the base 1 is fixed with insertion rods 18. The lower end of the insertion rods 18 has a conical structure. The surface of the insertion rods 18 is fixed with barbs 19. There are at least four insertion rods 18, which are evenly distributed in a ring along the lower part of the base 1. In order to ensure the stability of the base 1 in the farmland, multiple insertion rods 18 can be inserted into the soil for multi-point positioning. The barb 19 structure can increase the ability to prevent the insertion rods 18 from falling out of the soil after they are inserted into the soil.

[0030] It should be further noted that an annular side plate 2 is fixedly sleeved on the surface of the transition pipe 12. The lower end of the side plate 2 is fitted to the upper end face of the water supply pipe 11, and the side plate 2 can play an auxiliary support role.

[0031] It should be further explained that threaded posts 21 are fixedly distributed at the lower end of the side plate 2. The threaded posts 21 are symmetrically arranged at both ends of the side plate 2. The surface of the water supply pipe 11 is fixed with a collar 20 by a bracket. The surface of the threaded posts 21 and the inside of the collar 20 are slidably connected. Through the cooperation of the threaded posts 21 and the collar 20, the transition pipe 12 and the water supply pipe 11 can be quickly positioned and connected.

[0032] It should be further noted that the lower end of the threaded column 21 is threaded with a threaded cap 22. One end of the threaded cap 22 is fitted to the end face of the collar 20, which can play an auxiliary locking role after the transition pipe 12 and the water supply pipe 11 are positioned.

[0033] It should be further explained that a motor 2001 is fixed to the upper end of the base 1 by a bracket. The motor 2001 has a drive shaft inside, and a drive gear 2002 is fixed to the end of the shaft. A linkage gear 2003 is fixedly sleeved on the surface of the transition tube 13. The drive gear 2002 and the linkage gear 2003 are meshed with each other. When it is necessary to make the far-end nozzle 15 and the near-end nozzle 17 rotate and adjust the spraying, the power of the motor 2001 is turned on. The motor 2001 is a waterproof model. The motor 2001 rotates through its shaft, which can realize the rotation of the drive gear 2002 and drive it by meshing with the linkage gear 2003. This can realize the rotation of the transition tube 13 based on the transition tube 12, thereby realizing the rotational spraying of multiple nozzles and increasing the irrigation range.

[0034] It should be further explained that an annular groove 3 is provided on the inner wall of the transition tube 12. The interior of the annular groove 3 is filled with a sealing ring 31. The sealing ring 31 is made of water-swellable rubber material. The inner side of the sealing ring 31 is tightly fitted against the surface of the transition tube 13. The sealing ring 31 can play an auxiliary sealing role when the transition tube 13 rotates based on the transition tube 12.

[0035] It should be further explained that an annular groove 32 is provided on the inner wall of the transition tube 12, and several sliders 33 are fixed on the surface of the transition tube 13. The sliders 33 are slidably arranged inside the annular groove 32. When the sliders 33 rotate in the annular groove 32, the vertical position of the transition tube 13 based on the transition tube 12 is stable.

[0036] It should be further explained that a filter screen 4 is embedded inside the upper end of the water supply pipe 11. The filter screen 4 is made of aluminum alloy wire mesh material. The upper end of the filter screen 4 is fitted to the lower end face of the transition pipe 12. The filter screen 4 can filter large particles of impurities during water supply to avoid clogging of the nozzle area.

[0037] Working method: This scheme forms a multi-stage waterway structure through water supply pipe 11, transition pipe one 12 and transition pipe two 13. Water enters from the horizontal end of water supply pipe 11 and is transported upward through the vertical section to transition pipe one 12 and transition pipe two 13. The remote sprinkler pipe 14 and the near sprinkler pipe 16 are symmetrically installed on the transition pipe two 13, which are connected to the remote sprinkler head 15 and the near sprinkler head 17 respectively. The remote sprinkler head 15 is responsible for covering the far-distance area centered on the base 1, while the near sprinkler head 17 irrigates the near-distance area, forming a layered sprinkler effect. This design solves the problem of uneven coverage of traditional sprinkler irrigation devices and ensures that farmland areas of different radii can be effectively irrigated. In addition, the symmetrical distribution of the two sets of sprinkler pipes enhances the water flow balance and avoids uneven spraying caused by insufficient water pressure on one side.

[0038] The rotation adjustment of the nozzles is achieved through a motor 2001, a drive gear 2002, and a linkage gear 2003. After the motor starts, the drive gear 2002 drives the linkage gear 2003 to rotate, causing the transition pipe 2 13 to rotate relative to the transition pipe 1 12, thereby driving the far-end nozzle 15 and the near-end nozzle 17 to rotate synchronously. This dynamic spraying method significantly expands the irrigation coverage area and reduces irrigation blind spots. To ensure rotational stability, the transition pipe 2 13 slides with the annular groove 2 32 through a slider 33 to prevent axial displacement. At the same time, the water-swellable rubber sealing ring 31 provides a dynamic seal in the annular groove 1 3 to prevent water leakage. This design is particularly suitable for field irrigation, can adapt to the water requirements of different crops, and improve water resource utilization.

[0039] The stability of this design is ensured by the structure of the insertion rod 18 and the barb 19. The insertion rod 18 is tapered, making it easy to insert into the soil, while the barb 19 enhances the pull-out resistance and prevents the device from tilting due to wind pressure or water flow reaction force. The multiple insertion rods 18 are distributed in a ring under the base 1, forming multi-point anchoring to ensure no displacement during irrigation. In addition, an aluminum alloy filter screen 4 is installed at the inlet of the water supply pipe 11 to intercept large particles of impurities such as mud, sand, and weeds, preventing nozzle clogging. The filter screen 4 fits snugly against the end face of the transition pipe 12, making it easy to disassemble and clean. This dual stabilization design makes the device suitable for soft or sloping soils, while the filtration system extends the service life of the nozzles and reduces maintenance frequency.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
