Impact viberating drilling appts.

The oil drilling of a ''shocking and vibration drilling device'', with the technical activity using a non-high-frequency components (clash hammer, slide-valve, etc.), relying on a hydraulic pulse oscillation cavity to produce pulse pressure fluctuation pump, playing a role in pistons to produce the vibration drilling pressure, it solves the short life of the existing drilling tools, and solves the problem of processing and maintenance. Its technical points in the main body of the device is with hydraulic pulse oscillation interior cavity and the pistons by a hydraulic pulse oscillation cavity pulse vibration, in the role of trigger device which produces on the piston fluid fluctuation, so that the pistons have a high-frequency vibration, driving the vibration of the drill, realizing the shock and vibration to drill, the device has a simple structure, long service life, easy maintenance and other advantages so that it can be extensively due to oil drilling site operations.
