AI Technical Summary
Traditional L-shaped wear-resistant plates suffer severe wear on railway screen cleaning machines, requiring regular replacement. The replacement process necessitates tools, poses safety hazards, and is inefficient.
A structure comprising an L-shaped wear-resistant plate and a stabilizing section was designed. The wear-resistant plate is quickly replaced without tools by machining and brazing the carbide sheet, combined with a lead screw moving mechanism and a gear rack mechanism.
This technology enables tool-free, quick replacement of wear plates, improving work efficiency, extending the service life of wear plates, and reducing replacement frequency and costs.
