Abstract

(57) [Summary] [Purpose] In order to wash barnacles and seaweeds mainly attached to road networks such as fixed nets and sack nets used in coastal fisheries, ships are installed from the sea at the original positions where nets are installed. In parallel with the traveling direction of the boat, it is pulled up to the ship side, after washing, it is reintroduced into the sea and it can be laid down and installed on the side of the ship [Structure] A mounting frame and support members on the side of the ship Consists of an attached table, rollers with projections for winding up the mesh before and after the table, and a driving device therefor

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a fishing net lifting device used for washing fixed nets and bag nets used in coastal fisheries.

[0002]

[Prior art]

 Barnacles, seaweed, etc. adhere to the fishing nets stretched in the sea, but if this progresses, the resistance of the ocean current will increase, leading to the loss and damage of the nets, and the fish that approached the nets along the nets It is well known that catch is drastically reduced due to lack of attraction, and therefore during the fishing season it is necessary to remove deposits on the net every other day when it is large, so the net must be manually removed from the installation site, The conventional method was to collectively mount on a fishing boat, take it back to the beach or port, wash, transport it to the original installation location again and lay it

[0003]

[Problems to be solved by the invention]

 The conventional method requires manual labor and requires a lot of labor and work time.Especially in fisheries where the population is aging, immediate improvement measures are required. To provide a net lifting device that enables washing operations by mechanizing net handling, reducing labor and greatly increasing work efficiency.

Means and action for solving the problem

 The configuration of this invention will be described together with its operation with reference to the drawings. Fig. 1 Front view when mounted on the side of a ship The relevant equipment mounted on the ship's side winds up a net with lead attached to the lower part on the port side in the direction of travel of the ship, pulls it up, and pulls the outer table frame. (4) shows a situation in which it passes the vessel side and is re-entered into the sea. In this case, the net can be lifted either in the water close to the sea surface or just above the water surface, and this can be done by changing the mounting position relationship between the pair of lower support members (3) and the ship side table frame (5). Is a plan view when mounted on the side of the ship. A pair of lower support members (3) are attached to the front mounting frame (1) and the rear mounting frame (2) of the ship, respectively, with the lower side of the ship side being lowered downward. Yes. A perforated table (8) to which the boat-side table frame (5) is attached is attached to the lower support member (3), and is mounted between the boat-side table frame (5) and the outer table frame (4). A roller with ear-side projections (6) and a roller with ear-side projections (7) are attached to each part. The height of the perforated table (8) located between the members on both sides of the outer table frame (4) and the ship-side table frame (5) is higher than the height of the upper surface. 8) When passing over, it does not protrude or fall on both sides. A roller drive source with sprocket (9)) is mounted on the upper part of the front mounting base (1), and a downward chain (11) that meshes with the sprocket is attached to the ship-side shaft of the roller with entry-side projection (6). Connected to one of the two sprockets (10), and the other two sprockets are a sprocket (13) attached to the ship-side shaft of the roller (7) with an output protrusion and a chain (12) connecting the sprocket (13). They are connected by. Since the projections are attached to the surfaces of the roller with projections on both sides (6) and the roller with projections on exit side (7), the net is wound up by the roller drive source (9), and the mesh and The force that meshes with the mesh where barnacles and the like are attached and pulls the mesh acts effectively. The shape of the protrusion is a kind of stripe-shaped uneven groove parallel to the rotation axis, a warp-like protrusion having an irregular arrangement, or a gentle mountain-like protrusion, and has elasticity. FIG. 3 is a left side view of the net mounted on the side of the ship. The net stretched wide under the sea has a chain (see FIG. 3) in which an input-side projection roller (6) and an exit-side projection roller (7) are driven by a roller drive source (9). When driven through 12), the mesh gradually overlaps in a pleated shape while being gradually narrowed by the action of the entry-side projection roller (6) with ears, and is lifted on the perforated table (8). Is transported backward. The net that has left the roller (7) with the projection on the exit side is again thrown into the sea and laid. When the net is hoisted at the original position, the ship will move forward by the unwound distance.

[0005]

[Effect of the invention]

 B) It provides a device for lifting and washing nets stretched in the sea at the original position where they are stretched, so that labor and time are greatly reduced. 6) and the roller (7) with the protrusion on the exit side have tapered ears at both ends, so that the net serves as a guide when winding up, pulling up, or re-laying the net by narrowing its width. ) Since the surface of the perforated table (8) is perforated, drainage during cleaning has the effect of being able to escape through the holes.

Claims (1)

[Utility model registration claims] (1) A mounting base, a support member and a table are mounted on a ship side of a ship, and a fishing net stretched in the sea is rotated at its original position by rotating a roller with projections mounted on front and rear sides of the table. A fishing net lifting device characterized in that it can be pulled up on a table while narrowing its width in parallel with the direction of travel of the ship, and can be re-laid after passing over the table.
