用于具有壳体和动力单元的破碎锤的耐磨板
摘要：
本发明涉及带有具有碎片通道的耐磨板系统的破碎锤。一种破碎锤，包括限定出内部腔体的壳体、具有前头部的动力单元以及耐磨板。动力单元布置在壳体的内部腔体中。耐磨板插设在壳体与动力单元的前头部之间。耐磨板包括限定出中心纵向轴线的体部。体部包括面部，该面部包括面部底端、沿着中心纵向轴线与面部底端成分隔关系的面部顶端、和沿着垂直于中心纵向轴线的横向轴线彼此成分隔关系的一对面部侧棱。面部包括交界表面，该交界表面限定出沿着中心纵向轴线延伸的至少一条通道，并与动力单元的前头部成最近的关系。
摘要（英）：

A demolition hammer includes a housing defining an interior cavity, a power cell having a front head, and a wear plate. The power cell is disposed within the interior cavity of the housing. The wear plate is interposed between the housing and the front head of the power cell. The wear plate includes a body defining a central longitudinal axis. The body has a face that includes a bottom end, a top end in spaced relationship to the bottom end along the central longitudinal axis, and a pair of lateral edges in spaced relationship to each other along a transverse axis that is perpendicular to the central longitudinal axis. The face includes an interface surface that defines at least one channel extending along the central longitudinal axis and that is in proximate relationship with the front head of the power cell.
