摘要： PURPOSE:To remove soil adhered to the tip tool of a civil working machine by vibrating the tip tool by providing an oil-pressure pulse generator to be driven by an oil motor in the oil-pressure circuit of an operational cylinder for the tip tool of the civil working machine. CONSTITUTION:An oil-pressure pulse generator 12 to be driven by an oil motor 11 is connected to the way of pipes 9 and 10 through which working oil is supplied to the operation cylinder 7 of a bucket 6. In the pulse generator 12, a rotator 16 is closely provided in the body 15 having oil-passing holes 13 and 14, and two switch grooves 18 and 19 leading to an annular groove 17 are provided in mutually opposite directions by shifting them through 90 deg. or 180 deg. on the surface. Oil-passing holes 20 and 21 leading to the grooves 18 and 19 as the rotator 16 turns are provided to the body, and the holes 13, 14, 20, and 21 are connected to the pipes 9 and 10. When turning the motor 11, a pulsative flow occurs in the pipes, the bucket is vibrated, and adhered soil is cleaned.
