FIELD: agricultural industry. ^ SUBSTANCE: tackle consists of an impounding part which includes a harvesting cloth and a net bag, which are made of water-permeable material, a top rope, a footrope the middle part of which is horizontal and conjugated with vertical end sections, baffles and lead weights. Tackle is provided with a vertical symmetry axis, and height of the harvesting cloth exceeds the height of the net bag mouth. Harvesting cloth is equipped with a load-bearing frame which includes at least one horizontal ledger and at least two vertical ledgers. Lower edge of the net bag mouth coincides with horizontal ledger positioned along upper rope. Ends of that rope are connected with lower rope, above its horizontal section, and ends of vertical ropes are connected with lower angles of the net bag mouth and the appropriate extreme points of horizontal section of lower rope. Sector of the harvesting cloth, which is located between horizontal rope and vertical rope corresponding to it, is made in the form of a right triangle. ^ EFFECT: general-purpose tackle used for harvesting the fishing grounds, and simplifying the tackle design so that it can be used with small-size ships. ^ 10 cl, 7 dwg |
