Claims

[Scope of Claim for Utility Model Registration] (1) A fishing net towing device installed on the deck of a ship, etc., for hoisting a fishing net to a predetermined position on the deck, which A slide table feeding mechanism includes a guide member arranged to extend in a predetermined direction, and a feed screw having a threaded portion on the outer circumferential surface thereof; a slide base that has an engaging portion that engages with the guide member and reciprocates in the direction in which the guide member extends as the feed screw rotates; a pair of rotating shafts that are driven to rotate in opposite directions; and each of the rotating shafts. a pair of spherical elastic bodies fixed to the net and arranged so that their circumferential surfaces are in pressure contact with each other; a net pulling mechanism section that inserts and pulls the net between the pair of spherical elastic bodies; A fishing net traction device, comprising: a support frame having a lower end fixed on the slide table and supporting the net traction mechanism above the deck. (2) A fishing net towing device installed on the deck of a ship, etc., for hoisting a fishing net to a predetermined position on the deck, and a guide arranged extending in a predetermined direction on the deck surface of the ship. a slide table feeding mechanism having a member and a feed screw having a threaded portion on its outer circumferential surface, the slide table feeding mechanism having an engagement that is placed on the guide member and engages with the threaded portion of the feed screw; A slide base that reciprocates in the direction in which the guide member extends as the feed screw rotates; a pair of rotating shafts that are driven to rotate in opposite directions; a pair of spherical elastic bodies arranged such that the mesh pulls the net between the pair of spherical elastic bodies and pulls the net; and a lower end thereof is fixed on the slide base. a fixed frame member that supports the net traction mechanism and allows the net traction mechanism to rotate about the fixed frame member in a plane substantially parallel to the surface of the deck; A fishing net traction device comprising: a support frame having a pivoting frame member connected to the support frame; (3) A fishing net traction device installed on the deck of a ship, etc., for hoisting a fishing net to a predetermined position on the deck, and a guide arranged extending in a predetermined direction on the deck surface of the ship. a slide table feeding mechanism having a member and a feed screw having a threaded portion on its outer peripheral surface; an engaging portion placed on the guide member and engaging with the threaded portion of the feed screw; a slide base that reciprocates in the direction in which the guide member extends as the feed screw rotates; a pair of rotating shafts that are driven to rotate in opposite directions; a net pulling mechanism section that includes a pair of spherical elastic bodies arranged so as to be in pressure contact with each other, and that inserts and pulls the net between the pair of spherical elastic bodies; The fixed frame supports a fixed frame member and the net traction mechanism, and the fixed frame is configured to rotate about the fixed frame member in a plane substantially parallel to the surface of the deck. a support frame having a rotating frame member connected to a member, a pair of the support frames are provided on the slide base, and a pair of the support frames are provided on the rotating frame of each of the support frames. A fishing net traction device in which a net traction mechanism is individually supported.
