Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a retractable sprinkler device for agricultural planting irrigation. Background Technology

[0002] Currently, in agricultural facilities, the existing irrigation methods used in small and medium-sized planting scenarios such as solar greenhouses and plastic greenhouses involve fixing water pipes to the top of the greenhouse and installing sprinklers on the water pipes. Water is sprayed from the sprinklers to irrigate the crops.

[0003] However, this method has the following drawbacks: First, it has poor adaptability to crop row spacing. In the current method, the positions of water pipes and nozzles are fixed, while the row spacing or row width of different crops are different (e.g., tomatoes are generally 1.2m and lettuce is generally 0.6m). Therefore, it cannot match the row spacing requirements when multiple crops are planted in the greenhouse, which can easily lead to irrigation blind spots or repeated irrigation. Second, it has low space utilization. Traditional sprinkler equipment (such as fixed sprinkler belts and handheld spray guns) either need to be laid on the ground in the greenhouse in advance, occupying the planting space in the greenhouse, or need to be operated manually, which is arduous and inefficient.

[0004] This utility model addresses the aforementioned technical problems through research and improvement. Utility Model Content

[0005] In view of the existing technical problems, this utility model provides a retractable sprinkler device for agricultural irrigation to solve the problems in the prior art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A retractable sprinkler system for agricultural irrigation includes a first vertical plate and a second vertical plate, with multiple water distribution pipes spanning between the first vertical plate and the second vertical plate, and two sets of sprinkler arm assemblies rotatably connected to each of the water distribution pipes. The spray arm assembly includes a first spray arm, on which a second spray arm is slidably connected in a horizontal direction. The inner cavity of the first spray arm is connected to the inner cavity of the second spray arm. The length of the spray arm assembly can be adjusted as the second spray arm slides along the first spray arm. Spray heads are distributed at the bottom of the first spray arm and the second spray arm.

[0007] Preferably, the first spray arm includes a first spray arm body, which is rotatably connected to the water distribution pipe through a connecting sleeve. The inner walls of the first spray arm body are provided with horizontal grooves, and spring plungers are distributed on the grooves. The second spray arm includes a second spray arm body, and both sides of the second spray arm body are provided with protrusions that slide in conjunction with the slide groove. The protrusions are provided with limiting holes that correspond one-to-one with the spring plunger.

[0008] Preferably, the connecting sleeve is connected to the water distribution pipe via a connecting ring; The connecting ring is fixed to the water distribution pipe. A bearing is installed inside the connecting ring. The outer ring of the bearing is fixedly connected to the connecting ring, and the inner ring of the bearing is fixedly connected to the connecting sleeve.

[0018] As attached Figure 1 -Appendix Figure 6 The illustrated retractable agricultural irrigation sprinkler system includes a first vertical plate 1 and a second vertical plate 2. Multiple water distribution pipes 4 span between the first vertical plate 1 and the second vertical plate 2, and the water distribution pipes 4 are detachably connected to the first vertical plate 1 and the second vertical plate 2. Two sets of sprinkler arm assemblies are rotatably connected to each of the water distribution pipes 4, forming two rows of sprinkler arm assemblies that correspond to the crop planting positions within the greenhouse. The water distribution pipes 4 are connected to an external water source via inlet pipes 41, and the inlet pipes 41 are equipped with a pump and valves.

[0019] To improve overall stability, an arched top plate 3 is detachably connected to the upper end of the first upright plate 1 and the second upright plate 2.

[0020] refer to Figure 2 and Figure 3 The spray arm assembly includes a first spray arm 6, on which a second spray arm 7 is slidably connected in the horizontal direction. The inner cavity of the first spray arm 6 is connected to the inner cavity of the second spray arm 7. During the sliding motion of the second spray arm 7 along the first spray arm 6, the length of the spray arm assembly can be adjusted to accommodate the row width of different crops. A sealing strip is provided at the connection between the first spray arm 6 and the second spray arm 7 to ensure a tight seal between them during the extension and retraction of the second spray arm 7 along the first spray arm 6, preventing water from leaking out from the connection point. Spray heads 8 are distributed at the bottom of the first spray arm 6 and the second spray arm 7.

[0021] refer to Figure 5 and Figure 6 The first spray arm 6 includes a first spray arm body 61, which is rotatably connected to the water distribution pipe 4 via a connecting sleeve 64. The inner walls of the first spray arm body 61 have horizontally arranged sliding grooves 62, on which spring plungers 63 are distributed. The second spray arm 7 includes a second spray arm body 71, one end of which can extend into the inner cavity of the first spray arm body 61. The second spray arm body 71 has protrusions 72 on both sides that slide in conjunction with the sliding grooves 62. Each protrusion 72 has a limiting hole 73 corresponding to a spring plunger 63. After the second spray arm 7 extends or retracts along the first spray arm 6 to its designated position, the corresponding spring plunger 63 will engage with the corresponding limiting hole 73 for positioning.

[0022] The bottom of the first spray arm body 61 is provided with a relief groove 66 near the end of the second spray arm 7. The relief groove 66 is provided with through holes 67 that correspond one-to-one with the nozzles 8 on the second spray arm 7. After the second spray arm 7 extends and retracts along the first spray arm 6 to its position, the nozzles 8 on the second spray arm 7 will be located at the corresponding through holes 67, thereby achieving normal water spraying.

[0023] refer to Figure 2 and Figure 4 The connecting sleeve 64 is connected to the water distribution pipe 4 via a connecting ring 5. The connecting ring 5 is fixed to the water distribution pipe 4, and a bearing 51 is provided inside the connecting ring 5. The outer ring of the bearing 51 is fixedly connected to the inner wall of the connecting ring 5, and the inner ring of the bearing 51 is fixedly connected to the connecting sleeve 64. A bracket is provided inside the connecting sleeve 64, and turbine blades 65 are distributed at the center of the bracket. With this configuration, when water flows into the connecting sleeve 64 through the water distribution pipe 4, the turbine blades 65 are driven to rotate under water pressure. The turbine blades 65 drive the connecting sleeve 64 to rotate around the axis of the bearing 51, thereby simultaneously rotating the spray arm assembly.

[0024] In use, the first upright plate 1 and the second upright plate 2 are fixed to the two sides inside the greenhouse, respectively. Then, the water distribution pipe 4, the arched top plate 3, and the sprinkler arm assembly are connected to the first upright plate 1 and the second upright plate 2. The water inlet pipe 41 is connected to the external water source and the water distribution pipe 4, respectively. The length of the sprinkler arm assembly is adjusted according to the row width of the crops planted in the greenhouse. Specifically, the second sprinkler arm 7 is pulled by hand to slide along the first sprinkler arm 6 until it matches the row width of the crops. At this time, the spring plunger 63 will automatically engage with the limiting hole 73 on the second sprinkler arm 7 to lock the length. After opening the valve and pump on the water inlet pipe 41, the water flow passes through the water distribution pipe 4, the turbine blade 65, the first sprinkler arm 6, and the second sprinkler arm 7 in sequence to fill the entire water flow channel. When the water flows through the turbine blade 65, it will impact the turbine blade 65 and then drive the entire sprinkler arm assembly to rotate around the axis of the bearing 51. At the same time, the water flow is sprayed out from the nozzle 8 to irrigate the crops.
