AI Technical Summary

Technical Problem

The existing integral casting structure of crusher hammers leads to uneven wear, requiring the entire hammer to be replaced, which increases maintenance costs. Furthermore, the uneven wear rate of different parts results in waste.

Method used

The crusher's segmented hammerhead features a modular design, which can be disassembled into multiple independent hammer blocks via a detachable hammering assembly. Partial replacement can be achieved using connecting bolts and reinforcing bolts, and transverse grooves and wear-resistant layers are engraved on the surface of the hammer blocks to enhance protection.

Benefits of technology

This allows for the replacement of only the hammer block when localized wear occurs, reducing maintenance costs, extending equipment lifespan, and improving work efficiency by optimizing stress distribution.

Abstract

This utility model proposes a segmented hammerhead for a crusher, relating to the field of mining machinery technology. It includes a base block with a connecting groove on its outer surface. A hammer handle is located inside the connecting groove, and an installation groove is located inside the hammer handle. A set of installation blocks is engaged inside the installation groove, and a hammering assembly is located on the outer surface of the installation blocks. This utility model adopts a modular design, using a detachable hammering assembly to disassemble the hammerhead into multiple independent hammer blocks. This allows for localized replacement of worn parts, effectively solving the problems of needing to replace the entire hammerhead when wear is uneven, uneven wear rates in different parts, and significant waste and increased maintenance costs for producers when the working surface wears quickly while the non-working surface remains intact. Furthermore, the transverse grooves engraved on the surface of the hammer blocks, combined with a wear-resistant layer, provide excellent protection for the hammerhead. The trapezoidal prisms on the back further disperse the impact force, effectively increasing the service life of the equipment.
