FIELD: geology.SUBSTANCE: invention relates to sampling, sea research, investigation of geological and biological sedimentary material. Sedimentation sampler comprises a conical funnel and a mechanism. At bottom, funnel has a box with segments in its lower part. Mechanism is composed of two spring-loaded coils, onto which from different drums and different sides is fed a waterproof tape. Segments are made with radius equal to radii of coils, and box is tightly in contact with surface of tapes. Tapes have engagement bands on edges and perpendicular to band, elastically protruding above surface of tape to form compartments of time. Width of bands of tape is equal to width of end discs of coils. Bound tapes are configured to be fed onto receiving drum having a power drive and arranged at an angle close to 90° to vertical of funnel.EFFECT: higher reliability and accuracy of collecting sedimentary material.1 cl, 2 dwg |
