Sampling device and method for detecting content of sulfide in oil field drilling mud

The invention relates to the field of oil field drilling mud detection equipment, in particular to a sampling device and method for detecting the content of sulfide in oil field drilling mud, the sampling device comprises a base, two limiting seats are symmetrically connected to the surface of the base in a sliding mode, a profiling mechanism is arranged on the surface of the base, and adjusting mechanisms are arranged on the profiling mechanism and the limiting seats. The profiling mechanism comprises a U-shaped mounting frame, the U-shaped mounting frame is fixedly connected to the surface of the base, a stamping air cylinder is fixedly connected to the top end of the U-shaped mounting frame, and the bottom end of a telescopic rod of the stamping air cylinder penetrates through the U-shaped mounting frame and then is in sliding connection with the U-shaped mounting frame. By arranging the profiling mechanism and the adjusting mechanism, the diameter of the to-be-stamped cross rod can be automatically measur
