Impact hammer
The invention relates to an impact hammer. The impact hammer comprises a hammer body, the top of the hammer body is provided with a connecting part used for being connected with a driving mechanism, and the bottom of the hammer body is provided with an impact working face. The impact working surface is of a convex structure of which the center is low and the periphery is high; and a plurality of wear-resistant tooth blocks are convexly arranged on the impact working surface. According to the impact hammer, the convex structure with the low center and the high periphery is formed, namely, the shape that the center protrudes towards the impact acting surface is formed, so that the impact working surface forms a certain height gradient from the center to the edge, the impact hammer is stressed more dispersedly during impact work, the working efficiency is improved, and the service life of the impact hammer is prolonged. After being impacted by the convex impact working surface, the impact acting surface is concave, and the generated slurry can smoothly flow to the lowest position of the center, so that a pump body can be conveniently used for sucking subsequently; and a certain number of wear-resistant tooth blocks are further arranged, so that the wear resistance of the impact working surface is improved, and the service life of the impact hammer is prolonged.
本发明涉及一种冲击锤，其包括锤体；所述锤体的顶部设置有用以与驱动机构连接的连接部，所述锤体的底部设置有冲击工作面；所述冲击工作面呈中心所处高度低、四周所处高度高的凸形结构；所述冲击工作面凸起设置有若干耐磨齿块。通过形成中心低四周高的凸形结构，即形成中心处朝向冲击作用面凸出的形状，使所述冲击工作面沿中心向边缘形成一定的高度梯度，所述冲击锤在进行冲击工作时受力更为分散，有助于提高工作效率，且在受到凸形的冲击工作面冲击作用后，冲击作用面呈凹形，产生的泥浆能够流畅地流动至中心最低处，以便于后续使用泵体进行抽吸；进一步设置一定数量的耐磨齿块，提高了所述冲击工作面的耐磨性，提高了所述冲击锤的使用寿命。
