AI Technical Summary
Existing trenchers are prone to clay formation in cohesive soils, which increases trenching resistance, affects work efficiency and speed, and may even cause blockages.
A submersible pump and a rotary nozzle system are used to flush the surface of the trenching shovel, and the inner plate and the hidden plate are vibrated by a micro motor, which combines water flow and mechanical vibration to remove clay.
It effectively reduces the amount of clay on the surface of the trenching shovel, lowers trenching resistance, and improves trenching speed and efficiency.
