Embodiment Construction
[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the embodiments described in the accompanying drawings.
[0027] like figure 1 It is a schematic diagram of the main structure of an embodiment of the present invention. figure 2It is a schematic diagram of the pneumatic hydraulic hammer hydraulic system of the embodiment of the present invention. When working, the piston rod (27) is connected with the hammer core. During the lifting stage, the system supplies high-pressure oil to the hydraulic cylinder (26) through the oil supply control valve (25) from the external hydraulic pump (22) and high-pressure accumulator (24). Under the action of pressure oil, the piston and piston rod (27) drag the hammer core up to the set height, at this time the oil supply control valve (25) is closed; the hammer core will continue to move upward due to inertia, and ...
