Raft comprised by floating structures features lifting device with chain wheel or cogwheel gears with drive and arched or tilted guide lines. Lifting device is mounted over belt conveyor on raft comprised by floating structures. Guide lines for running wheels of lifting device are positioned at the edges of the raft. Lifting device is connected at two sides by cables to electric winches. Lengthwise axes of collector cable rows are positioned between cogs of carding device. Carding device can card oysters from collector cable surface for transportation of oysters by belt conveyor to grading and processing department. Wells with young oysters are transported and fixated at raft bottom and placed into water for nursing and fattening to commercial size. ^ EFFECT: enhanced productivity, improved conditions of oyster keeping. ^ 11 dwg |
