The structure of the hydraulic vibration crushing hammer gun head is mainly divided into three large parts: the upper cylinder body (nitrogen chamber), the middle cylinder body (oil cylinder), and the lower cylinder body, which are connected by four full body bolts. The upper cylinder block is used to store low-pressure nitrogen gas, while the middle cylinder block contains pistons, accumulators, oil seals, ventilation valves, etc. The lower cylinder block contains steel drills, flat pins, horizontal pins, inner and outer bushings, etc.
