Then, as shown in FIG. 5, the base end portion 8a of the horizontal swing arm 8 is rotatably supported by the support shaft 9 provided upright on the base frame 7 substantially at the center of the upper surface 7a of the base frame 7. ing. The horizontal swing arm 8 transmits the driving force of a desired horizontal swing motor 10 arranged in the base frame 7 by an appropriate transmission mechanism (not shown) such as a gear or a roller chain to horizontally swing. It is possible. That is, the horizontal turning arm 8 can be turned clockwise or counterclockwise about the support shaft 9 by the driving force of the horizontal turning motor 10 as shown by a double-headed arrow in FIG.

A horizontal turning means 11 is formed by the horizontal turning arm 8, the support shaft 9 and the horizontal turning motor 10.

As shown in FIG. 5, the free end portion 8b of the horizontal swing arm 8 extends upward from the base end portion 8a and is formed so as to get over the port side 4, and the lower surface shown in the lower part of the figure. One end of a desired lift arm 13 is rotatably attached to this via a desired lift arm attachment member 12 formed in a substantially U-shape.

Further, as shown in FIG. 6, a desired lift arm cylinder mounting member formed in a substantially U shape is formed on the left surface of the free end portion 8b of the horizontal pivot arm 8 shown on the left side in the drawing. One end of the desired lift arm cylinder 15 on the rod 15a side is rotatably attached via 14. The tip of the rod 15a of the lift arm cylinder 15 is rotatably attached to a desired lift arm cylinder rod mounting member 16 disposed on the upper left surface of the lift arm 13 in the longitudinal direction in the figure. That is, by expanding and contracting the rod 15a of the lift arm cylinder 15, the lift arm 13 can be rotated about the mounting point with the lift arm mounting member 12 as the fulcrum P0.

To the left of the lift arm 13, a net arm cylinder 17 is arranged so as not to interfere with the rod 15 a of the lift arm cylinder 15 and the lift arm cylinder rod mounting member 16. One end of the net arm cylinder 17 on the upper side in the drawing is rotatably attached to a desired net arm cylinder mounting member 18 formed in a substantially U shape disposed on the upper left side of the lift arm 13.

A detachable catcher 23 of a desired size is attached to a free end portion 21b shown below the net arm 21 in the figure. As shown in FIG. 8, the capturing body 23 forms a substantially rectangular parallelepiped frame by the bone portions 23a made of a desired material having rigidity, and the five faces of the hexahedron are formed by the desired net 23b. A desired opening 23c is formed on the upper surface in the drawing.

The net arm 21 and the capturing body 23 form a capturing means 24.

Next, the operation of the above-mentioned conventional fish intake device 1 will be described.

As shown by the broken line in FIG. 6, in the standby state, the horizontal swing motor 10 is stopped, and the free end portion 8 b of the horizontal swing arm 8 is made substantially orthogonal to the port side 4 from the port side 4. It is located so as to be separated. The rod 15a of the lift arm cylinder 15 is shortened, and the lift arm 13 and the net arm 21 are horizontally positioned toward the stern side. In other words, the opening 23c of the trap 23 is positioned horizontally on the stern side ES so as to face the sea surface.

Then, after the fish 26 such as a tuna caught on the fishing hook 25 is drawn to below the sea surface W L near the port side 4 of the tuna boat 2, first, the lift arm cylinder 15 is driven. 6, the lift arm 13 starts to rotate counterclockwise about the fulcrum P0, and the capturing body 23 immerses below the sea surface WL while directing the opening 23c toward the bow side TS, as shown in FIG. The capture start state is shown by the solid line.

Next, when the lift arm cylinder 15 is stopped and the net arm cylinder 17 is driven in the capture start state, the extension motion of the rod 17 a of the net arm cylinder 17 is moved by the straight link 19. It is transmitted to the net arm 21 via the arcuate link 20 whose position is restricted, and the net arm 21 starts rotating counterclockwise about the fulcrum P1 and the capturing body 23 moves upward through the opening 23c. While facing, the fish 26 such as a tuna is scooped away from the sea surface WL, the opening 23c of the catcher 23 faces upward, and the scooping state shown by the alternate long and short dash line in FIG. 6 is obtained.

Next, while continuing the driving state of the net arm cylinder 17, the lift arm cylinder 15 is driven so that the rod 15a of the lift arm cylinder 15 is shortened, so that the net arm 21 moves at the fulcrum P1. Continuing to rotate counterclockwise around the center, the lift arm 13 starts to rotate clockwise around the fulcrum P0, so that the opening 23c of the capturing body 23 is kept upward. Then, when the capturing body 23 is positioned above the port side 4 where the port gate 5 is formed, the capturing start state shown by the two-dot chain line in FIG. 6 and the solid line in FIG.

Next, when the lift arm cylinder 15 and the net arm cylinder 17 are stopped in the loading start state, the horizontal turning motor 10 is driven so that the horizontal turning arm 8 turns counterclockwise. The capturing body 23 crosses over the port side 4 and enters the capturing state shown by the alternate long and short dash line in FIG.

Next, in the take-in state, after stopping the horizontal turning motor 10, the fish 26 such as tuna scooped by the catching body 23 is taken out from the opening 23c of the catching body 23 by a human power or the like, and the inside of the ship (hull 3 The loading of the tuna 26 is completed by loading it on the deck 6).

Then, after the tuna 26 has been taken in, the horizontal swing motor 10 is driven so that the horizontal swing arm 8 swings clockwise or counterclockwise, and the catching body 23 is passed over the port side 4. After that, the net arm cylinder 17 is driven and the rod 17a of the net arm cylinder 17 is shortened to return to the standby state shown by the alternate long and short dash line in FIG.

By repeating the above-described state, it is possible to sequentially take in fish 26 such as tuna caught on the fishing hooks 25 of a large number of branch lines.

When all the fish 26 such as tuna have been taken in, the horizontal swivel motor 10 and the horizontal swivel arm 8 are rotated counterclockwise so that the fish swallowing device 1 in the fetched state shown by the one-dot chain line in FIG. By driving so as to rotate in the direction of and the end of the capturing body 23 is positioned at the stern side ES, the storage state shown by the chain double-dashed line in the figure can be obtained. In the stored state, the capturing body 23 is detached from the net arm 21 as needed.

[0024]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, when the fish 26 such as tuna is scooped into the catching body 23, the catching body 23 moves along the port side 4 of the hull 3 from the stern side ES toward the bow side TS toward a constant locus. When the fish 26 cannot be picked up by the catch 23, the fish 26 hooked on the fishing hook 25 must be surely pulled to the port side 4 so that the fish 26 caught on the fishing hook 25 is positioned on the turning trajectory of the catch 23. There was a problem that there was. When the fish 26 picked up by the catching body 23 is taken into the ship, the catching body 23 is horizontally swung from the outside of the port side 4 to the inside of the ship so as to get over the port side 4, so complicated operation is required. In addition, it takes a lot of time to store the fish 26 scooped by the catcher 23 in the ship, resulting in inferior efficiency. Furthermore, when the scooped fish 26 is taken into the catcher 23, the opening 23c of the catcher 23 faces upward, and it takes a lot of effort to take out the scooped fish 26 from the catcher 23. There was a problem.

That is, by expanding and contracting the rod 17a of the net arm cylinder 17, the net arm 21 is rotatable about the attachment point with the lift arm 13 as the fulcrum P1.

A rotating means 22 is formed by the lift arm 13, the lift arm cylinder 15, the net arm cylinder 17, the straight link 19, and the arcuate link 20.

A detachable catching body 35 having a desired size is attached to a free end portion 21b shown below the net arm 21 in the figure. As shown in FIG. 4, the capturing body 35 forms a substantially rectangular parallelepiped frame by the bone portion 35a made of a desired material having rigidity, and at the same time, the bottom surface inside the hexahedron and the five side surfaces are formed. A desired net 35b is covered, a desired opening 35c is formed on the upper surface in the figure, and a substantially rectangular notch opening 36d is formed on one side facing the port side 4. The shape of the cutout opening 35d can be selected from various shapes such as an inverted triangle and a trapezoid.

The net arm 21 and the capturing body 35 form a capturing means 37.

Next, the operation of this embodiment having the above-mentioned configuration will be described.

As shown by the broken lines in FIGS. 2 and 3, in the standby state, the vertical rotation cylinder 30 is stopped, and the free end portion 29b of the vertical pivot arm 29 is arranged to be substantially in direct contact with the port side 4. It is located so as to be separated from the port side 4. The rod 15a of the lift arm cylinder 15 is shortened, and the lift arm 13 and the net arm 21 are positioned horizontally toward the stern side ES.

That is, the opening 35c of the catcher 35 is positioned horizontally on the stern side ES so as to face the sea surface, and the notch opening 35d shown in FIG. 4 faces the port side 4. .

Then, the fish 26 such as a tuna caught on the fishing hook 25 at the tip of the branch rope 36 is pulled to the bottom of the sea surface WL near the port side 4 of the tuna boat 2 by pulling the branch rope 36, and then, first, the lift arm. When the working cylinder 15 is driven, the lift arm 13 starts rotating counterclockwise about the fulcrum P0 as the rod 15a of the lift arm cylinder 15 extends, and the catching body 23 opens the opening 23c at the bow. It sinks under the sea surface WL toward the side TS, and the capture start state shown by the solid line in FIG. 2 is reached.

Next, when the lift arm cylinder 15 is stopped and the net arm cylinder 17 is driven in the capture start state, the extension motion of the rod 17 a of the net arm cylinder 17 is moved by the straight link 19. It is transmitted to the net arm 21 via the arcuate link 20 whose position is restricted, and the net arm 21 starts rotating counterclockwise about the fulcrum P1 and the capturing body 23 moves upward through the opening 23c. While scooping the fish 26 while facing it, the fish 26 is separated from the sea surface WL, the opening 23c of the catcher 23 faces upward, and the scooping state shown by the alternate long and short dash line in FIG. 2 is obtained. At this time, when the vertical rotation cylinder 30 of the vertical rotation means 34 is driven, the capturing body 35 is brought into contact with or separated from the port side 4, for example, in a direction orthogonal to the port side, as shown by a chain line in FIG. Since they can be separated from each other, the rotation locus of the catcher 35 can be freely adjusted, and unlike the conventional case, the fish 26 can be scooped more reliably only by pulling the fish 26 near the port side 4. it can.

Next, by driving the lift arm cylinder 15 so that the rod 15a of the lift arm cylinder 15 is shortened while continuing to drive the net arm cylinder 17, the net arm 21 moves the fulcrum P1. Continuing to rotate counterclockwise around the center, the lift arm 13 starts to rotate clockwise around the fulcrum P0, so that the opening 35c of the catcher 35 is kept upward. Then, when the catcher 35 is positioned so as to face the port side 4 on which the port gate 5 is formed, the capturing state shown by the alternate long and two short dashes line in FIGS. 2 and 3 is obtained.

Next, after the lift arm cylinder 15 and the net arm cylinder 17 are stopped in the taken-in state, the fish 26 scooped by the catching body 35 is manually fed from the notch opening 35d of the catching body 35. The fish 26 is completely taken in by taking out the fish 26 and taking it into the ship (on the deck 6 of the hull 3).

That is, unlike the conventional case, when the fish 26 is taken in by the fish taking-in device 27 of this embodiment, it is not necessary to pass the catcher 35 over the port side 4, so that the fish such as tuna scooped by the catcher 35 is caught. It is possible to surely shorten the time until the 26 is accommodated in the ship, and to significantly improve the work efficiency and work ability. The fish 26 picked up by the catcher 35 can be easily accommodated in the ship by horizontally pulling out the notch opening 35d of the catcher 35 facing the port side 4 at a position facing the port gate 5 on the port side 4. Therefore, unlike the conventional case, it is possible to surely reduce the labor for accommodating the fish 26 in the ship.

After the fish 26 has been taken in, the net-arm cylinder 17 is driven to shorten the rod 17a of the net-arm cylinder 17 so that the standby state shown by the alternate long and short dash line in FIGS. Return to.

By repeating the above-described state, it is possible to sequentially take in fish 26 such as tuna caught on the fishing hooks 25 of a large number of branch lines.

When all the fish 26 have been taken in, the fish taking-in device 1 in the taking-in state shown by the chain double-dashed line in FIGS. 2 and 3 drives the vertical turning cylinder 30 of the vertical turning means 34. The vertical swivel arm 29 is swung counterclockwise in FIG. 1 so that the opening 35c of the capturing body 35 is positioned so as to face the deck 6, so that the chain double-dashed line in FIG. It can be stored as shown by the solid line. In the stored state, the net 35b of the catcher 35 can be easily repaired by removing the catcher 35 from the net arm 21 as needed.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made as necessary.
