The excavating hammer comprises a shell assembly, a driving source installed on the shell assembly, a hammer body assembly and a hook body assembly, the hammer body assembly comprises a hammer body arm connected with the output end of the driving source and a hammer head fixed to the hammer body arm, and the hook body assembly comprises a hook plate, a knocked body fixed to the upper end of the hook plate and hook teeth fixed to the bottom end of the hook plate. The hammer body arm and the hook plate are coaxially and rotatably installed on the shell assembly, and the hammer head can be in surface contact fit with a knocked body. According to the lever type rock digging device, the hook body assembly has vertically-downward high-speed impact force and transverse large digging force due to the arc-shaped movement track of the hook body assembly, the hook teeth at the lower end of the hook plate can impact and enter high-hardness rock, and the rock is dug out through lever type digging. Particularly, the hammer body arm and the hook plate rotate around the same rotating center line, and the arc-shaped movement tracks of the hammer body arm and the hook plate are consistent, so that the contact surface between the hammer head and a knocked body is always large and reliable, and the large digging force and the high-speed impact force of the hook body assembly are ensured.
本发明提供一种挖掘锤，包括壳体总成、安装于壳体总成的驱动源、锤体总成和勾体总成，锤体总成包括与驱动源的输出端相连的锤体臂、以及固定于锤体臂的锤头，勾体总成包括勾板、固定在勾板上端的被敲击体、以及固定在勾板底端的勾齿，锤体臂和勾板同轴可转动地安装于壳体总成，锤头能与被敲击体面接触配合。本申请中，勾体总成的弧形运动轨迹使勾体总成具有竖直向下的高速冲击力和横向的大挖掘力，勾板下端的勾齿能够冲击进入高硬度岩石，通过杠杆式挖掘将岩石挖出。特别是，锤体臂和勾板绕同一根转动中心线转动，锤体臂和勾板的弧形运动轨迹是一致的，使得锤头和被敲击体之间始终接触面大且可靠，保证勾体总成的大挖掘力和高速冲击力。
