Abstract

The assembly comprises a frame-truss subassembly, to which are attached an internal subassembly for directing a flow of encountered water during dragging and a subassembly for collecting and discharging shellfish. An external subassembly is used for encasing the frame- truss subassembly together with the internal subassembly and the subassembly for collecting and discharging shellfish. The frame-truss subassembly includes a pair of lateral trusses, spaced at a distance commensurable with a width of the assembly. The internal subassembly includes an anterior panel with a forwards oriented concavity and a posterior panel with a backwards oriented concavity. The subassembly for collecting and discharging, disposed behind the internal subassembly includes a louver platform, a grid receptacle supported by the platform and a mechanism for topple over the grid receptacle. At least two sets of a multiplicity of hinged flaps are used.

Claims

What I claim is:
1. An assembly for harvesting shellfish such as scallops and alike comprising a frame-enclosure truss subassembly to which are attached internal means for directing a flow of encountered water during a dragging operation of said assembly for harvesting shellfish;

means for collecting and discharging harvested shellfish; and external means for encasing said frame-enclosure truss subassembly together with said internal means for directing a flow of encounter water during dragging;

said frame-enclosure truss subassembly including a pair of lateral trusses extending longitudinally and spaced at a distance commensurable with a working width of said assembly for harvesting shellfish;

said internal means for directing a flow of encountered water during a dragging operation including an anterior, curved panel having its concavity forwards oriented and a posterior, curved panel having its concavity backwards oriented, said anterior and posterior curved panels being flanked by said pair of lateral trusses;

said means for collecting and discharging harvested shellfish, disposed behind said internal means for directing a flow of encountered water during a dragging operation, including a louver type grille-platform, a metal grid receptacle supported by said louver type grille-platform and a mechanism for topple over said metal grid receptacle when loaded with shellfish; and at least a pair of sets of a multiplicity of hinged flexible flaps being used, a first, front one being attached to a lowest part of said internal means for directing a flow of encountered water during a dragging operation, where said anterior and posterior curved panels meet, while a second multiplicity of hinged flexible flaps being attached at a frontal part of louver type grille-platform.
