Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation vehicle accessories, and particularly relates to a floating irrigation joint connection structure. Background Art

[0002] In the technical field of irrigation vehicles, irrigation vehicles usually adopt a towing structure, that is, the front side is a traction vehicle, and the rear end is a traction-type hose retracting device. Water is transported to the irrigation point through the hose. When the water source is sprayed to the surface, a spray rack is used to connect with the delivery pipeline. In the existing technology, such a spray rack is connected to the pipeline on the traction vehicle by a joint fixed to one body. Such joints are mostly hard connection structures, that is, the hose is connected to the metal pipe, and the metal pipe is then locked to the spray rack through a clamp to achieve water transportation.

[0003] The technical problem encountered at present is that this type of irrigation vehicle is mostly used in the field. Due to the uneven road environment in the field, the hard connection structure at the joint is prone to shaking and loosening when the vehicle moves. If it is exposed to the sun for a long time, it will also cause aging of the clamp. When the joint moves and causes stress concentration, the locking part of the clamp becomes a vulnerable part, which will cause water leakage or even cracking, affecting normal use.

[0004] In view of the shortcomings of the existing technology, as a researcher in this field, the technical problem that needs to be solved is: to design an irrigation joint connection structure, the purpose is to combine it with a soft connection structure, to avoid stress concentration at the joint through the soft connection, and to prevent damage to the connection parts caused by long-term vibration and shaking. Summary of the Invention

[0005] In view of the shortcomings of the existing technology mentioned above, the utility model proposes a floating irrigation joint connection structure, which is provided with a water delivery elbow, a rotating seat is provided on the water delivery elbow, and is connected to the spray rack through the rotating seat. A floating connection structure is provided at the axis of the rotating seat, which can achieve soft connection of the joint while ensuring the sealing effect, simplify the joint connection structure and reduce the failure rate of the joint position.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0010] The connecting pipe is connected to the hose through a clamp, and the hose is connected to the external water spray pipe.

[0011] The external water spray pipe comprises a transverse pipe and a vertical main pipe. Both ends of the transverse pipe are connected to the rotating frame, and the rotating frame is fixed on the upper rotating part of the turntable.

DETAILED DESCRIPTION

[0024] The present invention is further described below through an embodiment. As shown in the accompanying drawings, the following description is merely an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of the floating irrigation joint connection structure shall be based on the scope described in the claims.

[0025] Example 1:

[0026] A floating irrigation joint connection structure, as shown in the accompanying drawings, includes a water pipe 1. The water pipe 1 is a right-angle elbow structure. A bottom fixing frame 11 is provided at the bottom of the water pipe 1, which is fixed to the connecting component of the tractor section through the bottom fixing frame 11.

[0027] The top of the water pipe 1 is provided with a fixed plate 12, which is fixed to the external connecting beam 3. The rotating disk assembly 2 is fixed to the fixed plate 12, and a pipe head connection portion 13 is provided at the axis of the fixed plate 12. The pipe head connection portion 13 is a tubular structure that protrudes from the top surface of the fixed plate 12 and is in electrical communication with the water pipe 1. The pipe head connection portion 13 is provided with an embedded groove inside, through which a water seal 8 is fixed. The connecting pipe 4 is inserted into the pipe head connection portion 13 and the water seal 8 is arranged between the connecting pipe 4 and the pipe head connection portion 13. The water seal 8 is a multi-layer structure with upper and lower layers of screws stacked together, and the multi-layer sealing is achieved by the multi-layer axially spaced stacking of the screws. After the above plug-in structure is set up, the sealing between the connecting pipe 4 and the pipe head connecting part 13 can be guaranteed. However, when the high-pressure liquid is introduced, if there is no restraint, the high-pressure liquid will impact the connecting pipe 4 out of the inside of the pipe head connecting part 13. In order to prevent the above problems from occurring, the utility model makes the following improvements. An extension plate 41 is provided on the connecting pipe 4, and a fixing hole is provided on the extension plate 41. The extension plate 41 is connected to the upper rotating part 22 of the turntable assembly 2 through the fixing hole, and the lower rotating part 21 of the turntable assembly 2 is connected to the fixed plate 12; further, there are two extension plates 41 and they are evenly distributed on the periphery of the connecting pipe 4. In this embodiment, the extension plate 41 is welded and fixed to the outer wall of the connecting pipe 4, and the two form a whole. A long fixing hole 42 is provided on the extension plate 41 to realize axial displacement adjustment.

[0028] During assembly, the bolts for fixing the extension plate 41 and the upper rotating portion 22 are in a non-locked state, and a gap of less than 3 mm is left between the bottom surface of the bolt and the extension plate 41; after the high-pressure water source is introduced, the connecting pipe 4 is subjected to high-pressure impact and can have a floating adjustment range of about 3 mm in the axial direction, which can effectively avoid stress concentration at the fixing part of the connecting pipe itself, thereby causing cracks or leakage.

[0029] The top of the connecting pipe 4 is connected to a hose via a clamp, and the top of the hose is connected to an external water spray pipe. The external water spray pipe includes a horizontal pipe 61 and a vertical main pipe 6. The ends of the horizontal pipe 61 are connected to a rotating frame 7, which is fixed to the upper rotating portion 22 of the turntable with bolts.

[0030] The hose is a canvas hose 5, the upper end of which is connected to the vertical main pipe 6 via two upper clamps 52, and the lower end of which is connected to the connecting pipe 4 via a single lower clamp 51. The connection of the connecting pipe to the vertical main pipe via the canvas hose 5 effectively provides a flexible connection at the upper portion of the connecting pipe 4, preventing high-pressure water shock from the water source outlet and stress concentration between the connecting pipe 4 and the external connection. This structure allows the canvas hose 5 to buffer the energy from regular or irregular shocks when the high-pressure liquid is unstable, preventing problems such as leakage.

[0031] The present invention designs the rotating frame 7 into a U-shaped structure, with its left and right sides extending vertically, and vertical plates 71 are respectively provided on the top. The vertical plates 71 on the left and right sides support and fix the horizontal tube 61. This structure connects the rotating frame 7 with the horizontal tube 61 and the vertical main tube 6 to form a main body, thereby improving the overall strength.

[0032] To sum up, the floating irrigation joint connection structure has a simple overall structure and is easy to assemble. It can effectively avoid stress concentration after assembly. The components at the connection end can float and adjust themselves within a certain range after being impacted by high-pressure liquid to avoid leakage. It is an ideal floating irrigation joint connection structure.
