Air impact rapping hammer head of breaking hammer
The invention relates to an air impact rapping hammer head of a breaking hammer. The air impact rapping hammer head comprises a cylinder body, an upper hammer rod, a rapping rod and a lower hammer rod. The upper hammer rod, the lower hammer rod and the cylinder body form a rapping cavity, driving teeth with wedge-shaped sections are arranged on the lower end face of the rapping rod, and a wedge-shaped driving ring is formed. A wedge-shaped transmission ring is arranged on the upper end face of the lower hammer rod, and the wedge-shaped transmission ring and the wedge-shaped driving ring are meshed in a matched mode to form a transmission interlayer. A diversion channel is arranged in the rapping rod, an upper port of the diversion channel communicates with a pressure cavity, and a lower port of the diversion channel communicates with the transmission interlayer. A piston of the breaking hammer impacts the upper hammer rod to transmit impact force through the vibrating rod and the lower hammer rod in sequence, and axial multi-section breaking impact and circumferential rotary breaking of the lower hammer rod are achieved. A unique rapping structure is adopted, direct impact of the piston on the hammer head is effectively relieved, and the hammer head and a machine body can be better protected; and meanwhile, multi-leveled vibration crushing can be provided, and the working efficiency of the crushing hammer is improved.
本发明涉及一种破碎锤气冲振打锤头，包括缸体、上锤杆、振打杆及下锤杆；上锤杆、下锤杆及缸体形成振打腔，在振打杆的下端面设置有截面呈楔形的驱动齿，形成楔形驱动环；在下锤杆的上端面设置有楔形传动环，所述楔形传动环、楔形驱动环匹配咬合形成传动夹层；在振打杆的内部设置有导流通道，导流通道的上端口与压力腔连通，下端口与传动夹层连通；破碎锤的活塞通过撞击上锤杆将冲击力依次通过振打杆、下锤杆传递，实现下锤杆轴向的多段破碎冲击及周向的旋转破碎；本发明采用独特的振打结构，有效缓解活塞对锤头的直接冲击，能够更好的保护锤头及机体；同时能够提供多层次的振动破碎，提高破碎锤的工作效率。
