Abstract

PURPOSE: A device for opening and closing a casting net is provided to easily be used for a net fishing even if the diameter of the casting net is larger than 20 meters. CONSTITUTION: A casting net opening/closing cylinder(13) is assembled on a casting net opening/closing piston(12). Levers equipped in the piston(12) and levers equipped in the cylinder(13) are assembled by applying the levers(15) on a lower parts of the piston and cylinder, respectively. A piston base panel(11) is also equipped on an end of a crane(2), and rings(17) for folding the lower part of the casting net(16) are equipped on a lower part of each lever. Accordingly, rope strings(8) for folding the casting net(16) are hooked onto two rings with U-shape and inserted into an inner part of the piston(12) to fix a string(8) for folding the lower part of the casting net(16).

Description

Opening and folding netting device {omitted}

Conventional tug nets are thrown by hand to expand and fold the nets because it is impossible to use a large net because the weight is about 30kg, because the diameter of the unfolded net is about 2m small enough to catch a lot of fish can be used for leisure, the present invention It is possible to produce a large diameter of about 20m, so it is suitable as a professional fishing equipment, so fishermen can earn a lot of income with less money.

The present invention is to install the crane 2 of the simple structure in the bow portion of the small vessel (1) to hang the mesh opening and closing device at the end of the crane, and the mesh network 16 is connected under the mesh opening and closing device, the mesh opening and closing device is the opening and closing of the umbrella The principle is applied, and the umbrella's upper and lower sides are installed upside down. (See Fig. 5)

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

Combining the mesh opening / closing cylinder 13 to the mesh opening / closing piston 12 and a plurality of levers 15 at a distance of about 1 m each to the lower part of the piston and the lower part of the cylinder, thereby combining the lever installed in the piston and the lever installed in the cylinder together. And (see Fig. 2) as shown in Fig. 5 to make the piston intact so that the pin 14 fixed to the cylinder 13 is operated up and down like the cylinder, and the rope string 6 is connected to the pin. It is connected to the end of the crane is provided with a piston support plate 11 and the piston 14 is provided with a spring (14).

Under the mesh opening and closing device configured as described above, the mesh net 16 is connected to the bottom of the mesh net, and one below the lever is provided with hooks 17 for folding the mesh net bottom, respectively. (See Fig. 2) Inserted into the piston into the piston (15) to connect a number of rope rope (8 ') to the rope rope rope (8), hanging on the bottom of the mesh (18) hanging on the bottom of the bow The sonar 19 is provided.

Referring to the operation of the mesh opening and closing device configured as described above are as follows.

When fishing, when the fish appear on the sonar 19, the motors (5) are operated in the unfolded state on the surface of the mesh opening / closing device to loosen the rope strings (6) and (8) together, and then the fisherman quickly lowers the mesh. When it stops suddenly when entering the mesh, the cylinder 13, which is slightly tight, is lowered by the weight of the weight 18 and at the same time, the mesh is folded and the spring 14 is supported by the bottom. If you pull 1) manually about 1m, the bottom of the net will be folded well so that the fish will not fall out. And when unfolding the folded mesh again manually loosen the rope rope (8) about 1m and operate the motor (5) to pull the rope rope (6) (see Figs. 4 and 5) the top of the piston 12 is the piston support plate ( 11) The cylinder 13 rises at the same time as it reaches up to the bottom of the net, and the gap of the cylinder is slightly tight, so it does not fall naturally.The structure is simple and there is almost no breakdown and the net opening / closing time is within 5 seconds. It is a mesh opening and closing device that can.

This network switchgear is simple in structure, low in production cost and convenient to use, so it can be recognized as an essential equipment for catching fish worldwide.
