DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a diatom or a diatom attached to a glue net in a water tank on a ship when cutting a glue grown by a glue net in a seaweed culture carried out in the fishery and returning the net to the sea again. The present invention relates to fishing equipment for reducing the burden on fishermen who carry out acid treatment by lifting from the sea to a tank on a ship for removing microorganisms and sterilizing a glue net.

[0002]

2. Description of the Related Art Fishing equipment for raising fish or crustaceans used in fisheries, which raises a net from the sea floor. The net is placed on the upper surface of a rotating drive drum by rotating a drive drum with a net line holer shown in FIG. The rubber plate attached to the contact surface with the centrifugal force, the rubber plate of the drive drum sectional view shown in FIG. Now, fishing equipment is used to raise the net.

[0003]

When the fishing net described above in the prior art was used to raise a glue net on a ship, the rubber plate attached to the drive drum, and the uneven shape shown in FIG. The seams contained in the slimy and glue nets cause unevenness to be caught and almost no frictional resistance of the rubber.Therefore, the glue nets cannot be lifted on the ship at all by this method. It is an object of the present invention to provide a technique for easily taking the solution into a water tank containing an acid treatment liquid.

[0004]

Means for Solving the Problems To achieve the above object, the aquaculture glue net hoisting roller of the present invention is solved by improving the rubber plate portion attached to the drive drum, and the unevenness and arrangement shown in FIG. did it.

[0005] The shape protruding from the rubber plate to be attached to the driving drum, that is, the protruding portion 1 in Fig. 7 is a hemisphere obtained by cutting a sphere at a position of a diameter. Regarding the protrusion 2 in FIG.
The hemisphere has the same shape as the protruding portion 1 in FIG. 7, but has a shape which rises vertically from the rubber plate portion 4 in FIG. 8 and is integrated with the vertical portion 3 in FIG.

As for the position of the protrusion, the protrusion 1 of FIG. 7 is arranged at the corner of the square shown in FIG. 6, and the protrusion 2 of FIG. 8 is placed at the intersection of the diagonal lines. Two groups adjacent to one group of the upper, lower, left and right groups are shared, and the arrangement in the rotation direction is arranged endlessly,
In addition, by arranging the projections in accordance with the shape of the glue net, the arrangement with respect to the width is such that the mesh shown in FIG. .

[0007]

Embodiments of the present invention will be described with reference to the drawings. Raw rubber or synthetic rubber is used as the material of the rubber plate portion and the protruding portion attached to the drive drum core A in FIG.

[0008] The rubber plate portion is cylindrical or flat,
The thickness of the rubber plate is 5 mm to 15 mm at the maximum, and the protrusions 1 and 2 are integrally formed or pasted on the surface thereof. The cylindrical rubber plate 4 has an inner diameter of the driving drum core A.
The diameter is slightly smaller than the external dimensions of, and it is made to adhere to the elasticity of rubber when set. In the case of flat plate molding, the drive drum A is attached to the drive drum core A with an adhesive or integrated with the drive drum A by screwing.

To explain the positions of the protrusions shown in FIG. 6, the arrangement of the four protrusions is represented by points a, b, c, and d.
The protrusion 1 is placed at a rectangular position connecting the points. By arranging the projections 2 at the intersections e connecting the points a and d and the points c and b shown in FIG.
The four points b, c, and d all share the surrounding point e and are arranged endlessly.

The shape of the projection 1 in FIG. 7 is a shape in which a hemisphere obtained by cutting a sphere having a diameter of 20 mm to 40 mm in half is protruded from the rubber plate portion 4.

The protrusion 2 shown in FIG.
A vertical part 3 is set at a height of 1.5 mm to 3 mm on a hemisphere (same shape as the projection 1) in which a millimeter sphere is cut in half, and is integrated with the hemisphere. And the department. Therefore, the height is 1.5 mm to 3 mm higher than the protrusion 1 by the vertical portion 3.

[0012]

Since the present invention is constructed as described above, in one of the processes of glue cultivation, conventionally, the culture net is manually pulled into the water tank for acid treatment in the tank on the ship, and the work is performed. Fig. 2 Affixed to the drive drum core A instead of the previous one
The protrusion 1 shown in FIG. 7 and the protrusion 2 shown in FIG. 8 are provided on the rubber plate 4 of FIG.
By the arrangement of the seams contained in the seams included in the seams and the seams contained in the seams, the seams included in the conventional fishing equipment could not be slipped and pulled up by the shape and arrangement of this projection, Using the hook and slip efficiently, the glue net can be easily lifted into the acid treatment tank on the ship with mechanical power.
