Description

Technical Field

[0001] The utility model belongs to the technical field of connectors and relates to a truss connection device for a multi-section folding irrigation system. Background Art

[0002] At present, as a commonly used optional component of a sprinkler, a truss has the advantages of small pressure loss, water saving, being able to irrigate crops that are relatively fragile and cannot withstand water pressure impact, and uniform spraying. However, there are still certain deficiencies. For example, most of the trusses commonly seen on the market are multi-stage assembled and disassembled. When the operation of each truss width is completed, the truss needs to be disassembled step by step and hung on both sides of the sprinkler. After moving to the next working width, the work of installing the truss step by step needs to be repeated. The disassembly is relatively slow and the work efficiency is low. Moreover, most of the connections between each stage of the truss are only connected by a rotating shaft. Due to the gravity of the truss, the connection part is prone to deformation after long-term use. In order to prevent the truss from deforming, some trusses use steel wires to pull at the upper part. When folding, the steel wires need to be adjusted, and the effect of simply using steel wires for pulling is not good. There is a need for a folding truss that can meet the requirements of wide-width operation. The connection of this folding truss is convenient for installation and disassembly, time-saving and labor-saving, and the truss itself has sufficient strength and is not easy to deform. Content of the Utility Model

[0003] In order to solve the problems in the prior art that the folding truss needs to be installed or disassembled step by step, with a large workload, low work efficiency, and the connection part of the truss is easy to deform, the utility model provides a truss connection device for a multi-section folding irrigation system.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: A truss connection device for a multi-section folding irrigation system is arranged at the connection end of the upper-level truss and the lower-level truss, and includes an upper-level truss connection frame at the front end of the upper-level truss, a lower-level truss connection frame at the rear end of the lower-level truss, a locking component, and a swinging component;

[0030] Such as Figures 1-5As shown in the figure, a truss connecting device for a multi-section folding irrigation system is provided at the connecting end of the upper truss 1 and the lower truss 2, and includes an upper truss connecting frame 3 at the front end of the upper truss 1, a lower truss connecting frame 4 at the rear end of the lower truss 2, a locking assembly 6, and a swing assembly 5.

The locking assembly 6 is provided on the other side of the upper truss connecting frame 3. The outer sides of the upper truss connecting frame 3 and the lower truss connecting frame 4 are respectively connected to the swing assembly 6 through rotating members. A limit bolt 7 is provided on the other side of the lower truss connecting frame 4.

[0031] The support plate 8 includes a support plate body 8-1 and arc plates 8-2. A rotating member is provided between the arc plates 8-2 to connect with the side of the lower truss 4.

[0032] The locking assembly 6 includes a lower locking plate 6-2 and an upper locking plate 6-1, both of which are provided with a plate body 6-4 and a locking hook 6-5.

[0033] A tail handle 6-6 is provided at the tail end of the lower locking plate 6-2. A connecting rod 6-3 is provided between the lower locking plate 6-2 and the upper locking plate 6-1, and the connecting rod 6-3 is movably connected to both of them through a movable member.

[0034] The swing assembly 5 includes a driving member 5-1, an upper swing plate 5-2, and a lower swing plate 5-3. The end of the driving member 5-1 is movably connected to the frame body of the upper truss 1. As a preferred solution, the driving member in this embodiment is a hydraulic cylinder. One end of the upper swing plate 5-2 and the lower swing plate 5-3 is movably connected to the outer side of the upper truss connecting frame 3, and the other end is movably connected to the outer side of the lower truss connecting frame 4. The upper swing plate 5-2 and the lower swing plate 5-3 are movably connected through a rotating shaft 5-4.

By adjusting the truss, the requirements for different widths during irrigation can be met. The structure is simple, and the automatic folding of the truss is operated in an unmanned state, which is convenient. The installation and disassembly of this folding truss connecting device are convenient, saving time and effort. When the truss is folded, due to its sufficient strength, it is not easy to be distorted.
