This invention provides a sand-proof, non-magnetic hydraulic oscillator, relating to the technical field of hydraulic oscillators. The sand-proof, non-magnetic hydraulic oscillator includes an upper connector, one end of which is fitted with the oscillator body. A rotating impeller drives a rotating connecting shaft, which in turn drives a conveying auger. The conveying auger, in turn, drives a rotating scraper. The rotating scraper agitates the sand adhering to the surface of the sand-blocking filter, preventing a large amount of sand from accumulating on the filter surface.

This then drives the motor, preventing the accumulation of sand and gravel impurities in the medium between the rotor and stator after drilling stops, thus solving the problems of difficulty in restarting and jamming during construction.
