AI Technical Summary
The existing irrigation head unit fails to connect with different types of tractor vehicles due to interface incompatibility, requiring additional replacement of adapter parts, which significantly reduces operational efficiency.
An anti-detachment connection structure for the irrigation head vehicle was designed, including a triangular frame, a buffer rod, a hydraulic rod, a ball joint connection assembly, and a locking ring connection assembly. The hydraulic rod provides stable support, while the ball joint connection assembly and locking ring connection assembly adapt to the connection requirements of different traction vehicles. The buffer damper absorbs impact energy, ensuring the stability and flexibility of the connection.
It enables rapid adaptation between different traction vehicles, avoids connection failures, improves work efficiency, and prevents deformation or breakage of connecting parts in emergency situations, providing a stable working condition.
