In the process of field operation, due to the large area of ​​the field and the variety of crops planted in the field, in order to improve the efficiency of water replenishment operation, foldable trusses are often used in field irrigation robots to meet the requirements of field irrigation of different widths. As a commonly used optional component in reel-type sprinkler irrigation robots, the truss is used with sprinkler pipes to irrigate the field. It can irrigate crops that are relatively fragile and cannot withstand water pressure shocks, and has the advantages of uniform spraying.

[0003] At present, most trusses are fixed and disassembled. At the end of each operation, the truss arms need to be disassembled step by step. After moving to the next work site, the work of installing the truss arms is repeated. The operation is cumbersome, requires a lot of manpower and time, and has low work efficiency. Moreover, most of the truss arm joints only rely on hinges to bear the weight of the truss arm, which is easy to be damaged and deformed during use, affecting the mutual connection and use of the truss arms. There is a need for a connection device that can reduce the deformation of the truss arm joints and is easy to install. Utility Model Content

The upper support plate 3-1 and the lower support plate 3-2 are respectively arranged vertically with the fixing frame 2. A support column 3-3 is arranged between the upper support plate 3-1 and the lower support plate 3-2, and the support column 3-3 is located between the edges of the upper support plate 3-1 and the lower support plate 3-2 on the side close to the locking assembly 4. A slide groove 3-4 is arranged on the upper support plate 3-1, and the slide groove 3-4 is an arc-shaped through groove.

[0026] The connecting plate 1 is matched with the plate surface of the fixing frame 2, and the plate surface is square or rectangular. A limit bolt 6 is arranged on the outer side of the connecting plate 1. As a preferred solution, two limit bolts 6 are arranged in this embodiment.

[0027] The locking assembly 4 includes a lower locking plate 4-2 and an upper locking plate 4-1, both of which are provided with a plate body 4-4 and a locking hook 4-5.

[0028] A tail handle 4-5 is provided at the tail end of the lower locking plate 4-2; a connecting rod 4-3 is provided between the lower locking plate 4-2 and the upper locking plate 4-1, and the connecting rod 4-3 is movably connected to the two through a movable part.

[0029] The connecting plate 1 in the utility model is connected to the expansion arm of the irrigation robot, and a driving device is installed on the expansion arm, and the driving device drives the expansion arm to fold or unfold. When the expansion arm needs to be unfolded, the expansion arm and the connecting plate 1 rotate around the rotating member, and the movable bolt 5 on the connecting plate 1 slides in the slide groove 3-4 to play a role of limiting.
