AI Technical Summary

Technical Problem

The existing cutter suction rock prevention device of the dredger requires frequent disassembly of the limit strips when removing rocks, resulting in low work efficiency.

Method used

The design adopts a mud suction port, sliding block, fixed shaft, connecting rod and limiting rope. By stretching the fixed rod with a loose connection, the angle gap between the connecting rods becomes smaller to absorb the mud. After the debris is engaged, the fixed rod is pushed to make the angle gap larger, so that the gravel automatically falls off. The residue is cleaned by combining the rubber limiting rope and the motor-driven cleaning component.

Benefits of technology

The gravel can be removed without manual disassembly, which improves work efficiency, reduces manual operation time and reduces worker fatigue.
