Description

Technical Field

[0001] This utility model belongs to the technical field of reel-type sprinkler irrigation machines, specifically, it relates to a corrosion-resistant pipeline connection structure for reel-type sprinkler irrigation machines. Background Technology

[0002] In modern agricultural production, reel-type sprinkler irrigation machines play a vital role as a highly efficient and water-saving irrigation device. Their working principle is to extend and retract the pipeline by winding up and retracting the reel, thereby uniformly irrigating large areas of farmland.

[0003] In existing technologies, threaded connections are often used to connect pipes, and rubber sealing rings are added between the two pipes for sealing. However, due to the inherent characteristics of rubber sealing rings, they are difficult to completely fit the complex joint surface. In actual production and installation, slight unevenness is inevitable at the joint. Coupled with installation errors, ordinary rubber sealing rings cannot adapt to these differences, making it difficult to form an effective seal. This results in a significant reduction in the sealing effect. When reel sprinkler irrigation machines are used in humid and rainy areas, frequent rain and high humidity will further exacerbate the risk of corrosion at the pipe connection. No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a corrosion-resistant pipeline connection structure for reel-type sprinkler irrigation machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A corrosion-resistant pipe connection structure for a reel-type sprinkler includes a first hose connected to a sprinkler head and a second hose connected to the water inlet of the reel. An outer sleeve is fixedly connected to the end of the first hose furthest from the sprinkler head. A connector is threaded onto the outer sleeve, which has a groove through which an air bladder is tightly fitted. The air bladder is detachably mounted on the side of the connector near the outer sleeve. An air supply pipe is fixedly connected to the air bladder, and a sealing cap is threaded onto the air supply pipe. A gasket is tightly fitted between the end of the outer sleeve furthest from the first hose and the inner wall of the connector.

[0006] Preferably, the outer sleeve has a slot that is connected to the groove to facilitate the movement of the gas delivery pipe.

[0007] Preferably, a rotating plate is fixedly connected to the end of the connector away from the outer tube, and an annular plate is fixedly connected to the end of the second hose near the connector. The rotating plate and the annular plate are rotatably connected to facilitate the connection between the connector and the outer tube.

[0008] Preferably, a positioning block is fixedly connected to the airbag, and an arc-shaped groove is provided on the positioning block. The positioning block is in close contact with the elastic ring through the arc-shaped groove, which facilitates the detachable installation of the airbag.

[0009] Preferably, the end of the connector away from the second hose has a positioning groove, and the positioning block fits into the connector through the positioning groove, which facilitates the movement of the positioning block to connect with the connector.

[0010] Preferably, the connector has a limiting groove, and the positioning groove is connected to the limiting groove to facilitate the elastic ring to limit the positioning block.

[0011] In summary, the technical effects and advantages of this utility model are as follows: The corrosion-resistant pipe connection structure of this reel-type sprinkler irrigation machine allows the first and second hoses to be detachably installed together through the cooperation of the outer sleeve and the connector. The cooperation of the groove and the air bladder further increases the sealing between the outer sleeve and the connector. Furthermore, the cooperation of the air supply pipe and the sealing cap facilitates the entry or exit of gas into or out of the air bladder, thereby sealing the external connection between the outer sleeve and the connector. It can adaptively deform according to the shape of the connector, reducing the sealing gap caused by minor unevenness or installation errors at the connection, preventing the infiltration of water and corrosive substances, and ensuring that the pipe connection is leak-proof during long-term operation of the sprinkler irrigation machine.

[0012] The positioning block and positioning groove enable precise positioning and installation of the airbag. The combination of the arc groove, limiting groove and elastic ring limits the positioning block, allowing the airbag to be detached from the connector, thus facilitating airbag maintenance and replacement.

[0015] This utility model provides a corrosion-resistant pipe connection structure for a reel-type sprinkler irrigation machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0016] Reference Figure 1-4 A corrosion-resistant pipe connection structure for a reel-type sprinkler includes a first hose 1 connected to a sprinkler head and a second hose 2 connected to the water inlet of the reel. An outer sleeve 3 is fixedly connected to the end of the first hose 1 furthest from the sprinkler head. A connector 4 is threaded onto the outer sleeve 3, and the outer sleeve 3 is compatible with the connector 4. A groove 7 is formed on the outer sleeve 3, and an air bladder 8 is tightly attached to the outer sleeve 3 through the groove 7. The groove 7 is compatible with the air bladder 8. The air bladder 8 is detachably installed on the side of the connector 4 near the outer sleeve 3. An air supply pipe 9 is fixedly connected to the air bladder 8, and a sealing cap 10 is threaded onto the air supply pipe 9. The air supply pipe 9 and the sealing cap... The 10-phase adapter has a gasket 17 tightly attached between the end of the outer tube 3 away from the first hose 1 and the inner wall of the connector 4. The gasket 17 is mainly made of rubber and has a certain elasticity. After the outer tube 3 and the connector 4 are threaded together, the gasket 17 seals the connection between the inner parts of the outer tube 3 and the connector 4. At this time, the airbag 8 is located inside the groove 7. Gas is injected into the airbag 8 through the air supply pipe 9. The airbag 8 then expands to fit tightly against the groove 7. Subsequently, the sealing cap 10 quickly seals the air supply pipe 9, thereby sealing the connection between the outer tube 3 and the connector 4 and preventing the infiltration of water and corrosive substances.

[0017] Reference Figure 2-3 The outer tube 3 has a slot 11, which is connected to the groove 7. After the airbag 8 moves into the groove 7, the air supply tube 9 moves into the slot 11, which facilitates the movement and adjustment of the air supply tube 9.

[0018] Reference Figure 2 A rotating plate 5 is fixedly connected to the end of the connector 4 away from the outer tube 3, and an annular plate 6 is fixedly connected to the end of the second hose 2 near the connector 4. The rotating plate 5 and the annular plate 6 are coaxial and rotatably connected. During the rotation of the connector 4, the rotating plate 5 rotates accordingly. Through the action of the annular plate 6, the outer tube 3 and the connector 4 are threadedly connected.

[0019] Reference Figure 2-3A positioning block 12 is fixedly connected to the airbag 8. Multiple positioning blocks 12 are arranged in a circular array on one side of the airbag 8. An arc-shaped groove 13 is opened on the positioning block 12. The number of arc-shaped grooves 13 is equal to that of the positioning blocks 12, and they correspond one-to-one. The positioning block 12 is closely attached to the elastic ring 16 through the arc-shaped groove 13. After the airbag 8 moves to the connector 4 through the positioning block 12 and the arc-shaped groove 13, the elastic ring 16 is sleeved on the positioning block 12 through the arc-shaped groove 13, thereby limiting the positioning block 12.

[0020] Reference Figure 3 The end of the connector 4 away from the second hose 2 has a positioning groove 14. The positioning block 12 fits into the connector 4 through the positioning groove 14. The number of positioning grooves 14 and positioning blocks 12 are equal and correspond one-to-one. The positioning groove 14 facilitates the precise movement of the positioning block 12 to connect with the connector 4.

[0021] Reference Figure 3 A limiting groove 15 is provided on the connector 4. The positioning groove 14 is connected to the limiting groove 15. The limiting groove 15 is adapted to the elastic ring 16. After the positioning block 12 moves to connect with the connector 4, the elastic ring 16 limits the positioning block 12 through the limiting groove 15 and the arc groove 13.

[0022] Working principle: First, fix one end of the first hose 1 to the nozzle, and fix one end of the second hose 2 to the water inlet end of the reel. The other end of the second hose 2 is connected to the connector 4 through the rotating plate 5 and the annular plate 6. Move the gasket 17 into the inside of the connector 4. The connector 4 rotates and moves towards the second hose 2, so that the outer tube 3 and the connector 4 are connected together. At this time, the gasket 17 is compressed and deformed. The positioning block 12 is inserted into the positioning groove 14 at one end of the connector 4. The elastic ring 16 is tightly attached to the positioning block 12 through the limiting groove 15 and the arc groove 13, and the positioning block 12 is limited. This allows the airbag 8 to be detachably installed on one end of the connector 4. The airbag 8 is moved into the inside of the groove 7, and the air supply pipe 9 is moved into the slot 11. Gas is injected into the inside of the airbag 8 through the air supply pipe 9, so that the airbag 8 expands to be tightly attached to the inner side wall of the groove 7. Then, the sealing cap 10 is used to quickly seal the air supply pipe 9, thereby sealing the external connection between the connector 4 and the outer tube 3.
