Description

Fish and shellfish catchers

The present invention relates to a shellfish and crustacean trap that can more efficiently catch the shellfish and crustaceans that grow on the seabed, such as sea farms.

Generally, crustaceans such as fish, shellfish, and seashells, or shellfish such as shrimp and crabs, grow on the bottom of the seabed. In order to capture the fish and shellfish that grow on sandfields, gravel fields, and tidal flats, divers dive directly There is a method of capturing fishery and crustaceans with a net pocket while allowing the vessel to drag the catcher while the catcher attached to the frame and the net bag attached to the frame by the traction line.

The former case has been pointed out to be a problem that not only is the catch efficiency low but also a risk, because the divers have to pick up or catch fish and shellfish by hand while submersing. The latter case is fixed at the front of the lower part of the frame. As the number of hooks attached at intervals moves forward by digging the bottom of the seabed, it is possible to dig and catch the shellfish and crustaceans buried or hidden in the sand, gravel fields or tidal flats of the seabed. As you can expect, the problem is that sand and tidal masses dug up by a number of hooks do not disperse quickly and stay in front of the hooks, causing resistance to the catcher's forward movement, or the hooks being deeply embedded in the sea floor. When the phenomenon appears, the trap There is a problem that the catch efficiency of fish and shellfish and shellfish falls due to not being able to move at the same speed and heavy loads on the vessel that pulls the catcher. The shellfish or crustaceans dug together with sand or mud flats were not put into the net pockets, but stayed in front of the hooks so that they could not be caught off the left or right side of the net pockets.

The present invention was created to solve the above problems of the prior art, the shellfish and crustaceans hidden in the bottom of the seabed by the hook as a means for injecting water pressure from the front of the hook of the harvester and at the same time exposed by the water pressure It aims to increase the catching efficiency of fish and shellfish as it enters the net bag, and it is also a means of attaching ski members to the frame and the net, so that the catcher itself slides on the bottom of the seabed so that the hooks are undersea. There is another purpose to ensure that the net and net bag can be moved without being buried in the bottom, and not to be buried in the bottom at all times. Other Will you ever.

Figure 1 is a state diagram for explaining the present invention, Figure 2 is a perspective view of a capture device that is the main portion of the present invention, Figure 3 is an enlarged cross-sectional view showing an operating state of the present invention,

Reference numeral 1 denotes a frame woven in a rectangular shape, and a mesh net 2 made of metal is attached to the rear lower end of the frame 1 so as to be freely moved up and down by a hinge or the like. Many hooks 3 inclined downward are attached at regular intervals.

In addition, the inlet portion of the mesh bag 4 is attached to the entire rear of the frame 1 and the rear end of the mesh body 2.

A hydraulic pressure distribution tube 6 is attached to the free ends of the supporting rods 5 which are fixed to the upper and lower ends of both sides of the frame 1 and extended in the forward direction.

The hydraulic pressure distribution tube 6 has a hydraulic injection hole 61 formed at an upper portion of the middle portion thereof, and a plurality of horizontal and inclined hydraulic pressure components are provided at a rear portion of the hydraulic pressure distribution cylinder 6 facing the frame 1. The pipes 62 and 63 are attached at regular intervals, and the water pressure injection pipe 62 in a horizontal state among the above-mentioned water pressure injection pipes is configured to inject water pressure upwards of the hook 3, and the inclined water pressure The injection pipe 63 is comprised so that it may inject toward the sea bottom in front of the hook 3.

The hydraulic pressure injection port 61 of the hydraulic pressure distribution tube 6 is connected to a supply hose 72 produced by the hydraulic pump 71 installed in the ship 7, the suction hose 73 of the hydraulic pump 71 is It is comprised so that sea water can be inhaled in the state extended by the ship 7 underwater.

That is, when the hydraulic pump 71 is operated, the sea water is sucked and pumped into the suction hose 73 and injected into the hydraulic pressure distribution tube 6 through the supply hose 72, followed by a plurality of hydraulic spray pipes 62 and 63. It is configured to spray water pressure.

The lower end of the frame (1) is attached to the main ski member (8) that slides in contact with the bottom of the seabed, and also the smaller size than the main ski member (8) on both sides of the bottom of the mesh (2) Auxiliary ski member 81 is attached.

On the other hand, the catcher configured as described above is connected to the vessel 7 by the tow line 9, the connection position of the tow line 9 connected to the catcher when the drag itself is taken to the ship 7 the bottom of the seabed It is preferable to attach the frame 1 or the hydraulic pressure distribution cylinder 6 as a position that can be moved in a sliding manner, and the hydraulic pressure distribution cylinder 6 installed in front of the frame 1 to be detachable. However, this is to make it possible to dismantle the hydraulic distribution container (6) and to carry out the catching operation when it is easy to catch fish and shellfish and crustaceans even without spraying water pressure because the bottom is very soft. It is preferable to adjust the installation angles of the hydraulic spray pipes 62 and 63 according to the state of the tidal flat or gravel.

When explaining the action to capture the shellfish and crustaceans as the present invention made of such a member as follows.

As shown in FIG. 1, the main ski member 8 attached to both sides of the bottom of the frame 1 and the auxiliary ski member 81 attached to the bottom of the mesh 2 come into contact with the bottom of the seabed, and then the frame 1 Alternatively, when the other end of the tow line 9, which is tied to both sides of the hydraulic distribution container 6, is tied to the ship 7, the catcher also moves forward as the ship 7 slides on the bottom of the sea as the ship 7 proceeds. When the supply hose 72 of the hydraulic pump 71 installed in (7) is connected to the hydraulic inlet 61 of the hydraulic distribution container 6, the preparation procedure for capturing fish and shellfish at the bottom of the seabed is completed. In such a state, if the hydraulic pump 71 is operated while driving the vessel 7 by dragging the catcher, the shellfish and shellfish, such as shellfish and seashells, which are hiding at the bottom of the sea floor, are captured.

That is, when the ship 7 pulls the catcher, a plurality of hooks 3 attached to the frame 1 in an inclined downward direction at the bottom of the frame 1 move forward while being embedded at a certain depth in the bottom of the sea floor. The shellfish or crustaceans hidden in the area of the depth (3) are caught by the hook (3) and floated over the hook (3) together with the exposed sand mass or tidal mass simultaneously with exposure, while operating the hydraulic pump (71). The hydraulic pressure injected into the hydraulic pressure distribution tube (6) through the supply hose 72 is injected into a plurality of hydraulic injection pipes (62) (63), the front of the hook (3) of the plurality of hydraulic injection pipes The water pressure sprayed from the inclined hydraulic spray pipe 63 facing the bottom of the sea will act to dig the bottom of the hook in front of the hook 3 so that the hook 3 can easily dig the bottom of the sea. Sand or It blows out the tidal flats to expose shellfish such as shellfish or shrimp, so that they are well floated on the hooks (3), and the horizontal hydraulic spray pipes (62) facing the upper part of the hooks (3) are hooks. (3) By injecting water pressure upwards, the shellfish or crustaceans injured above the hooks (3) are quickly sucked into the net bag (4), and the injured sand or tidal flats such as shellfish or crustaceans It is broken and scattered by a function to disperse, and the net mesh (2) attached to the lower rear of the frame (1) is a small gravel (mixed in the sand lumps or tidal masses dug by the hook (3) ( Stone blocks will come out.

Therefore, after being injured on the bottom of the seabed by the hook 3, the shellfish or crustaceans are sucked into the net bag 4 by hydraulic pressure without leaving the frame 1, so that an increase in capture efficiency can be expected.

And the main ski member (8) attached to both lower ends of the frame (1) is to guide the catcher itself to move as if sliding on the bottom of the seabed and at the same time the hook (3) does not get stuck to the bottom of the sea floor only a predetermined depth It is to be able to dig to act to prevent the heavy load is applied to the vessel (7) towing the catcher.

In addition, since the auxiliary ski member 81 attached to the bottom of the mesh 2 also slides in contact with the bottom of the sea floor, the mesh 2 is moved at a predetermined height apart from the bottom of the sea bottom. As described above, the mesh bag 4 attached to the mesh 2 is able to capture fish and shellfish while the bottom side of the net bag 4 is moved to a floating state without touching the bottom of the seabed. In addition, to prevent damage to the closed end, and the mesh (2) is attached to the frame (1) with a hinge so that the auxiliary ski member 81 is bent on the bottom of the seabed with a curved surface even when the bottom of the seabed is bent The frame 1 itself, which is moved by the ship 7, can be kept vertical all the time because it is moved as it slides while moving up and down while being touched, and the shellfish and crustaceans dug out by the hook 3 Is to be is to be accurately flows into the inside of the frame (1) improved trapping efficiency by the water pressure to be injected in the pressure injection pipe (62).

According to the present invention as described above, the main ski member attached to both bottom of the frame of the catcher is to move forward in the state in which the catcher itself is separated from the bottom of the seabed by a certain height, and at the same time so that the hook is always dug only a predetermined depth It is easy to tow the catcher and has the effect of capturing only the shellfish or crustaceans to be caught simultaneously, and the inclined hydraulic injectors among the hydraulic injectors installed horizontally and inclined in the hydraulic distribution container have a seabed in front of the hook. Digging the bottom with hydraulic pressure to expose the shellfish or crustaceans and to facilitate the excavation of the hook. Horizontally extending hydraulic injectors spray the water pressure toward the net pocket to injure the seabed by the hook. Fish or crustaceans are sucked into the net Therefore, there is an effect that can increase the catch of fish and shellfish and crustaceans, and the mesh formed at the lower rear of the frame is attached to the hinge to free up and down movement, and by the auxiliary ski member attached to the bottom As it moves on the bottom of the bottom of the curved surface while maintaining a certain height, the net bag can be protected from touching the bottom of the seabed. The water pressure injected into the hydraulic spray pipe is a hydraulic pump installed in the ship. It is an invention that provides a very easy advantage of the supply of water pressure by supplying the pump.
