A sampling device for recovery of cuttings suspended in a fluid, such as a drilling mud containing suspended cuttings produced in oil well drilling, comprising a slowly driven rotary drum having openings in its ends and riffle plates and into which the drilling fluid returning from an oil well is continuously discharged to settle and deposit the cuttings on the lower wall of the rotating drum, the supernatant fluid being continuously passed outward through an open end of the drum, the drum having vanes mounted on its wall which lift the settled cuttings, a series of nozzles disposed in the drum which discharge streams of water upon and wash mud from the cuttings in each vane as it unloads cuttings upon an angularly mounted trough centrally through the open ends of the drum, the trough having perforations at one end to classify the washed cuttings passing downward and outward of the drum, and having containers mounted beneath the perforations to collect the washed recovered cuttings.
