FIELD: technologies for extracting concretions from sea bottom.
SUBSTANCE: device has watercraft, extracting device with collecting means and pulp-pump, force pipeline, perforated branch pipe with sizes of opening less than minimal size of extracted concretions. Perforated branch pipe is positioned in portion of force pipeline adjacent to extracting device and is provided with flanges, and diameter of perforated branch pipe decreases away from extracting machine. Extracting machine is provided with additional pump with latch, mounted in parallel with pulp-pump of extracting machine, and between perforated branch pipe and force pipeline check valve is positioned.
EFFECT: higher efficiency.
