Description

Apparatus for picking up shellfish}

The present invention relates to a fishing net for collecting shellfish inhabiting the seabed.

Hedgehogs are known as equipment for collecting shellfish that inhabit the seabed. Hedgehogs collect shellfish that inhabit the surface of the sea while scraping the surface of the sea with a rake. In some cases, rakes are placed on obstacles such as rocks or rocks that are located on the surface of the sea. If the size of the rake is small and the obstacle is easily removed from the surface, the fishing gear can proceed without a big problem. However, when the obstacle is a heavy object such as a rock, the towing of the fishing gear becomes very difficult.

If the fishing gear is difficult to move due to an obstacle, the fishing gear must be retracted and then moved to bypass the obstacle. This process can take a lot of time and time, and can damage fishing activities. . In addition, when the fishing gear is seriously caught in the obstacle, the problem of damage to the fishing gear may occur, and in some cases, the situation may inevitably leave the fishing gear on the sea floor.

The first slide member 100 and the second slide member 200 may be formed symmetrically with respect to the center. Each of the first and second slide members 100 and 200 includes a bottom plate portion contacting the sea bottom and a vertical plate portion vertically coupled to the bottom plate portion. The bottom plate has a shape in which the front end is lifted up like a ski so that the bottom plate can slide smoothly on the seabed surface. The vertical plate portion has first guide grooves 110 and 210 extending in the vertical direction (± z direction), and second guide grooves positioned in front of the first guide grooves 110 and 210 and extending in the front-rear direction (± x direction). 120 and 220 are formed. The first guide grooves 110 and 210 may be formed in a curved shape toward the front toward the upper side. However, the shape of the first guide grooves 110 and 210 is not limited thereto and may be formed in various forms. For example, the first guide groove may be formed in a straight line, or may be formed to have an appropriate curvature in consideration of the movement path of the moving member 400 to be described later, even when formed in a curved line. The first slide member 100 and the second slide member 200 is preferably formed of a material such as stainless steel, which has sufficient rigidity and is resistant to corrosion even at the bottom of the sea.

The support member is for fixing the first slide member 100 and the second slide member 200 to each other, and consists of a plurality of rod members 300, 310, and 320 arranged in the width direction (± y direction) of the shape fishing gear 1. Can be. Each rod member 300, 310, 320 has one end coupled to the vertical plate portion of the first slide member 100 and the other end coupled to the vertical plate portion of the second slide member 200, and the first and second slide members 100 and 200. The bolts may be fastened to the first and second slide members 100 and 200 so as to be separated. Some of the rod members 300, 310, and 320 may be disposed at rear ends of the first and second slide members 100 and 200, and a mesh 900 may be mounted. In the present embodiment, the support member is described as having a plurality of rod members 300, 310, and 320, but the support member may be any plate-shaped or truss-shaped, as long as the first and second slide members 100 and 200 can be fixed to each other. Anything is possible. In addition, in addition to being fastened and coupled to the first and second slide members 100 and 200, the support member may be permanently fixed by welding. The support member, like the first and second slide members 100 and 200, is preferably made of a material having sufficient rigidity and hardly causing corrosion even at the seabed.

The moving member 400 is disposed between the first and second slide members 100 and 200, and is formed to extend in the width direction (± y direction) of the shaped fishing gear 1 of the present embodiment. 2 is a view schematically showing an end portion of the first sliding member 100 of the moving member 400. In FIG. 2, only one end portion of the movable member 400 is illustrated, but since the movable member 400 has a symmetrical shape with respect to both sides of the center, the other end of the movable member 400 is moved in FIG. 2. It can be seen that it has the same shape symmetrically to one end of the member 400.

1 and 2, support plate portions 410 are disposed at both ends of the moving member 400, and a plurality of rod members 422, 424, 426 are fixedly coupled to the support plate portion 410. Reinforcing bars 432, 434, and 436 may be disposed between the rod members 422, 424, and 426 of the movable member 400 to effectively increase the overall rigidity of the movable member 400. As such, when the movable member 400 is configured to have a truss shape using the linear rod members 422, 424, 426 and the reinforcing bar, there is an advantage in that high rigidity relative to the weight of the movable member 400 is obtained. In the present exemplary embodiment, the moving member 400 includes a plurality of rod members 422, 424, 426, but the moving member 400 may have various shapes such as a plate shape or a tubular shape. The moving member 400 is also preferably made of a material having sufficient rigidity and high corrosion resistance at the bottom of the sea.

Protruding portions 415 protruding in the width direction of the netting gear 1 are formed at both ends of the moving member 400, which are fitted into the first guide grooves 110 and 210 formed in the first and second slide members 100 and 200, respectively. Lose. As such, the movable member 400 is coupled to the first and second slide members 100 and 200 while the protrusions 415 at both ends are fitted into the first guide grooves 110 and 210 formed of the first and second slide members 100 and 200. In addition, the first guide grooves 110 and 210 may be moved in the extension direction, as well as rotation in the pitch direction, that is, tilting in the front-rear direction. Although not shown in the drawings, a bearing may be disposed at the coupling portion of the movable member 400 and the first and second slide members 100 and 200 for smooth movement and rotation of the movable member 400. In the present exemplary embodiment, the vertical movement of the movable member 400 is guided by the protrusion 415 inserted into the first guide grooves 110 and 210, but as a guide member for guiding the vertical movement of the movable member 400. Various configurations can be employed. For example, a guide groove may be formed in the movable member 400 and a protrusion may be formed in the first and second slide members 100 and 200, as opposed to the present embodiment. The first and second slide members 100 and 200 may be formed. Instead of the first guide grooves 110 and 210, a rail extending in the vertical direction may be provided, and the moving member may be configured to be coupled to the rail so as to be slidable. In addition, in the present embodiment, the protrusion 415 has been described as the protrusions 415 at both ends of the moving member 400 are disposed in the middle of the support plate 410, but the protrusions 415 are among the plurality of rod members 422, 424 and 426. It may be arranged at various positions, such as being arranged on the same line as any one.

In addition, the moving member is provided with a bar 440 is disposed in the width direction of the netting gear 1, the bar 440 is coupled to the tent member 700 to be described later.

Rake 500 is to scratch the seabed surface, is coupled to the lower side of the moving member 400 is formed to extend in the lower direction (-z direction) and the front direction (+ x direction). The rake 500 is coupled to the reinforcing bar 434 disposed on the lower side of the reinforcing bar 432, 434, 436 of the moving member 400, and arranged side by side in the width direction (± y direction) of the shape fishing gear (1). Rake 500 may be fastened to the moving member 400 with a bolt to be replaced. The second bar 530 is fitted to the inside of the rake 500, the second bar 530 is fitted to the engaging portion 510 formed on the inside of the rake 500 is limited to movement. The tension member 550 is coupled to the second bar 530.

The seating member 250 is disposed to protrude inwardly of the first and second slide members 100 and 200, and the movable member 400 is disposed below the first and second slide members 100 and 200, that is, in the first position. Support the moving member 400 when positioned. When the seating member 250 supports the movable member 400, the movable member 400 is caught by the seating member 250 so that it is no longer inclined forward or backward. That is, the moving member 400 is limited in the rotation of the pitch direction by the mounting member 250. In addition, the moving member 400 is also limited in the rotation of the pitch direction by the tension member 550 that restrains the rake 500. On the other hand, when the moving member 400 is moved upward, since it is no longer caught by the seating member 250, it is possible to tilt in the pitch direction. Therefore, the moving member 400 may be said to be movable between a first position supported by the seating member 250 and a second position disposed upward from the first position and inclined in the pitch direction.

In addition, the mounting member 250 may be provided with a magnet. When the moving member 400 is a material receiving magnetic force such as stainless steel, the magnet applies magnetic force to the moving member 400 in a position where the moving member 400 is supported by the seating member 250, that is, in a first position direction. Add. When the attraction force acts between the magnet of the seating member 250 and the movable member 400 as described above, the movable member 400 is not in contact with the seating member 250 unless the movable member 400 receives a large force enough to overcome its own weight and magnetic force. The state, that is, the state of staying in the first position is stably maintained. In the present exemplary embodiment, the magnet is disposed on the seating member 250, but the magnet may be disposed on the movable member 400, and in the direction in which the magnet is exerted on both the movable member 400 and the seating member 250. It may be arranged. In addition, as a method of attracting force between the movable member 400 and the seating member 250, a method of installing a spring on the movable member 400 and the seating member 250 may be considered instead of the magnet.

The tent member 700 has a membrane shape and is coupled to the bar 440 provided on the upper side of the movable member 400, more specifically, the movable member 400. Since the tent member 700 receives the resistance of the water when the mesh fishing gear 1 is obtained, there is an effect of balancing the front and rear of the fishing gear 1. If there is no such tent member 700, the rear side of the shape of the net fishing gear is heavy and may sink first. In this case, the net 900 may cover the fishing gear. However, the mesh fishing gear 1 of the present embodiment can effectively solve this problem by providing the tent member 700. In this embodiment, the tent member 700 has been described as being disposed above the moving member 400. Unlike the present embodiment, the tent member 700 is coupled to the upper side of the support member or the first and second slide members ( It may be arranged in a form of directly coupling to the upper side of the 100,200.

The first bar 600 is disposed at the front side of the moving member 400, and both sides of the first bar 600 are fitted into the second guide grooves 120 and 220 of the first and second slide members 100 and 200. Accordingly, the first bar 600 may move in the front-rear direction (± x direction) with respect to the first and second slide members 100 and 200. Since the first bar 600 is connected with the rope 650, which is connected to the ship, the traction force of the ship is transmitted to the mold fishing gear (1). In the present exemplary embodiment, the first bar 600 is inserted into the second guide grooves 120 and 220 of the first and second slide members 100 and 200, and thus the first bar 600 is disposed to be movable. And it may be fixed to the second slide member (100,200), as shown in Figure 7 of the patent application No. 10-2010-0087675 by the applicant, the hinge on the first and second slide member (100,200) It may be combined.

The tension member 550 is a rope connecting the first bar 600 and the second bar 530. In the present embodiment, since the first bar 600 is movable in the front-rear direction (± x direction), when the first bar 600 is moved forward by the traction force of the ship, the tension member 550 is pulled tautly, The second bar 530 is pulled forward. That is, while the traction force of the ship is dispersed, the traction force is applied directly to the rake 500 through the second bar 530, it is possible to reliably tow the netting gear (1). The turn buckle 555 may be disposed in the tension member 550, and the turn buckle 555 may easily adjust the tension force acting on the tension member 550.

The buoyancy member 800 is coupled to the first and second slide members 100 and 200 and has a specific gravity smaller than that of water to provide buoyancy to the shaped fishing gear 1. The buoyancy member 800 may be configured in the form of a hollow cylinder, or may be formed of a styrofoam material having a specific gravity that is much smaller than water. By adjusting the buoyancy of the netting gear 1 by using the buoyancy member 800, since the netting gear 1 can reduce the pressing force on the seabed, the frictional force between the netting gear 1 and the seabed can also be reduced. have. Therefore, the mesh fishing gear 1 can move more smoothly on the seabed.

The mesh 900 is disposed at the rear side of the moving member 400 and is coupled to the support members 310 and 320 disposed at the rear of the mesh gear 1. The mesh 900 may hold the shellfish when the shellfish is separated from the seabed by the rake 500.

Next, the operation form of the mesh fishing gear 1 of this embodiment is demonstrated.

The fishing net 1 of the present embodiment is loaded on a ship and moved to an area where shellfish are expected to inhabit, and then the fishing net 1 is put in the water. The netting gear 1 sinks by its own weight and rests on the seabed. Since the shape fishing gear (1) is generally used in the soft soil area where shellfish inhabit, the rake of the shape fishing gear (1) is inserted into the sea bottom when the shape fishing gear (1) is seated on the sea bottom. In this case, as shown in FIG. 3, the moving member 400 of the mesh fishing gear 1 is stably fixed to the first position while receiving a magnetic force by the magnet of the seating member 250.

If the tongs are towed in the state where the rake 500 of the tongs 1 is inserted into the seabed, various shellfish inhabiting the seabed are separated from the seabed by the rakes of the tongs. Shellfish separated from the seabed is passed through the rake 500 and the moving member 400 enters the mesh 900 disposed in the rear of the netting gear (1).

FIG. 4 is a view schematically showing a state when the fishing net 1 of the present embodiment encounters an obstacle R such as a rock while moving.

Referring to FIG. 4, while the fishing net 1 moves on the seabed G, the rake 500 may be caught by an obstacle R such as a rock. When the obstacle R is caught by the rake 500 of the mesh gear 1, the rake 500 receives torque in the pitching direction by the resistance of the obstacle R. When the obstacle R is heavy and the resistance by the obstacle is sufficiently large, the torque acting on the rake 500 due to the resistance of the obstacle R is caused by the weight of the moving member 400 and the magnetic force of the seating member 250. Will surpass. Therefore, the moving member 400 is rotated in the pitching direction, the rake 500 is pushed back relatively. When the rake 500 is pushed backward, the tension member 550 connected to the rake 500 is pulled tightly to limit the rotation of the movable member 400, thereby protruding both ends of the movable member 400. The 415 rides up the first guide grooves 110 and 210. That is, the moving member 400 rotates in the pitching direction by the obstacle R and moves upward, that is, moves to the second position. In this case, the first bar 600 may be shifted in the front and rear directions according to the distance between the tensile force acting on the tension member 550 and the moving member 600.

As described above, the mesh fishing gear 1 of the present embodiment can be operated very smoothly when there are no obstacles, and can be overcome very quickly without having to bypass the obstacles when the obstacles are met. Therefore, when the rake 500 is caught by the obstacle during the operation, since the operation to reverse the shape of the fishing gear 1 and bypass the obstacle is not taken, the situation in which the operation is delayed even if the fishing gear 1 meets the obstacle, can be effectively reduced. Can be. In addition, the conventional fishing net (1) can be easily used even in areas where operation was difficult, for example, a region where obstacles such as rocks are somewhat distributed.

FIG. 5 is a view schematically showing a state after the mesh fishing gear 1 of the embodiment passes through the obstacle R. As shown in FIG.

Referring to FIG. 5, when the shaped fishing gear 1 passes the obstacle R, the moving member 400 returns to its original state from the pushed-out state, and is lowered by the magnetic force received from the seating member 250. That is, it moves to the first position. The rake also pulls the movable member 400 downward while digging the seabed G. At this time, since the rake 500 is constrained by the tension member 550, more than a certain range is not pushed back.

When the movable member 400 returns to the first position as described above, the mold fishing gear 1 according to the present embodiment is in the state of FIG. 3 again, and thus continuous operation is possible. In this way, the mesh fishing gear 1 of the present embodiment is returned to a state where the operation is possible immediately after overcoming the obstacle. Thus, even if an obstacle is encountered, the operation can be performed continuously without interruption or delay.

As described above, unlike the conventional fishing net (1), the netting gear 1 according to an embodiment of the present invention can easily overcome obstacles and can quickly return to operation even when the obstacles are met, so the catch amount compared to the same operation time Very high. In addition, the problem that the form fishing gear is damaged or lost due to the obstacle can be effectively solved.

Next, a mesh gear phrase according to another embodiment of the present invention will be described.

6 is a schematic perspective view of a fishing net according to another embodiment of the present invention. Referring to FIG. 6, the fishing net according to the present embodiment is similar to the fishing net of the embodiment of FIG. 1. 2 Slide member 200, support member, moving member 400, seating member 251, rake 500, tent member 700, first bar 600, tension member 550, buoyancy member 800 And a mesh 900. Since each component of the mesh fishing gear 2 of the present embodiment is very similar to the fishing gear 1 of FIG. 1, redundant description thereof will be omitted and the differences will be mainly described.

7 is an enlarged view of a portion of the fishing net of FIG. 6, more specifically, a coupling portion of the second slide member 200 and the moving member 400. Since the fishing gear of the present embodiment has a form that is symmetrical, the coupling portion of the first sliding member 200 and the moving member 400 is substantially the same as the structure of FIG. Therefore, hereinafter, only the coupling portion of the second sliding member 200 and the moving member 400 shown in FIG. 7 will be described.

Referring to FIG. 7, a first guide groove 210 is also formed in the vertical plate 202 of the second slide member 200 of the mesh fishing gear 2 according to the present embodiment, and the first guide groove 210 is formed at a lower end side of the first guide groove 210. The clearance groove 211 is formed to extend in the direction intersecting the extension direction of the one guide groove 210, that is, the front-rear direction. The clearance groove 211 serves to allow movement of the moving member 400 in the front and rear direction to some extent. When the clearance groove 211 is formed in the first guide groove 210 as described above, the movable member 400 is predetermined according to the tensile force acting on the tension member 550 or the resistance force of the seabed surface acting on the rake 500. You have the flexibility to move within range. In addition, when the first bar 600 is fixedly coupled to the first and second slide members 100 and 200, the traction force acting on the gear net is directly transmitted to the rake 500 while the moving member 400 moves instead. You can do that.

The support plate portion 410 of the moving member 400 of the present embodiment includes a protruding member 411 protruding upward of the second sliding member 200, and the protruding member 411 and the second sliding member 200. The mounting member 251 is disposed between the vertical plate portions 202. That is, in this embodiment, the seating member 251 is disposed above the second sliding member 200 unlike the embodiment of FIG. 1. The seating member 251 of the present embodiment may also include a magnet capable of applying an attractive force to the moving member 400. The bottom of the sea floor may include various objects reacting to the magnetic force. Thus, when the seating member 251 and the magnet are disposed on the upper side of the shaped fishing gear 2, the occurrence of such objects on the magnet may be significantly reduced. Can be. Therefore, the reduction of the magnetic force can be effectively suppressed.

While the description has been given of the form fishing gear according to an embodiment of the present invention, this is merely exemplary, and the present invention may be embodied in various forms without being limited thereto.
