DEVICE FOR GATHERING OF CONCRETIONS FROM BOTTOM OF DEEP WATER RESERVOIRS Russian patent published in 1996 - IPC

FIELD: mining industry, particular, devices for underwater mining of concretion from the bottom of seas and oceans. SUBSTANCE: device working member is made in form of through 1 with vibration exciter 2 attached to frame 4 by means of flexible ties 3. Load carrying surface of trough 1 has longitudinal corrugations whose wall width and angle of inclination to surface connecting the tops of corrugations is determined by the relations given in the invention description. During movement, vibrating trough 1 penetrates with its part 12 into layer of bottom sediments 13. Concretions from trough 1 move to unloading trough 15 in which concretions are caught with teeth 18 and get into buckets 17 of drum 16 and then, to screening surface 22 of conveying screen. EFFECT: higher efficiency of gathering due to provision of continuous concretion mining and reduced losses in movement of the device over slope on the bottom of water reservoir. 6 dwg
