The present invention provides a chisel for a hydraulic crusher, which is installed in the hydraulic crusher and hit by a reciprocating piston, comprising: a chisel main body having a shaft body structure provided with a horn-shaped crushing part at the lower end; and a stress distribution portion provided in a concavo-convex form in which a plurality of grooves and protrusions are alternately formed in the longitudinal direction on the outer circumferential surface of the chisel body, and disperses stress waves transmitted from the upper side to the lower side of the chisel main body by the impact of the piston and stress waves transmitted from the lower side to the upper side of the chisel main body by the impact of the crushing portion on an object to be crushed.
本发明提供一种液压破碎机用凿子，其安装在液压破碎机内并被往复运动的活塞撞击，包括：凿子主体，其具有在下端设置有喇叭形粉碎部分的轴体结构；和应力分配部分，其设置成凹凸形式，其中多个凹槽和突起在所述凿子主体的外周面上沿着纵向交替地形成，并且分散通过所述活塞撞击从所述凿子主体的上侧传递到下侧的应力波和通过所述粉碎部分撞击被破碎物从所述凿子主体的下侧传递到上侧的应力波。
