[0002] Cast steel components such as liners and jaw plates in mining machinery are subjected to strong impacts and abrasive wear during operation, resulting in short service life, frequent replacements, long equipment downtime, and high maintenance costs.

The dovetail groove and buffer connection structure effectively absorb and disperse impact energy during operation, protecting the wear-resistant layer from brittleness and reducing equipment operating noise. The wear-resistant working layer adopts a segmented design; when a segment wears to its limit, only that segment needs to be replaced, eliminating the need to replace the entire liner, significantly saving maintenance costs and downtime. Alternatively, less worn areas can be moved to worn-through areas, and areas lacking wear-resistant segments can be filled, greatly improving utilization. Attached Figure Description
