DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recovering fallouts when raising cultured marine products such as cultured oysters, cultured scallops, and cultured seaweed.

[0002]

2. Description of the Related Art Conventionally, harvesting of cultivated marine products such as oysters is generally carried out by using a guide reel mounted on one side of a recovery vessel and a rope winding machine (hydraulic or electric) mounted on the other side.
With this, the rope with oysters is pulled up from the sea. That is, as shown in FIG. 1, a rope 2 to which oysters 1 or the like 1 are attached is first hung on a guide reel 3, and the tip of the rope 2 is further wound by a winding machine 4. in this case,
One of the ropes 2 is wound up, and the other is attached with oysters 1 and the like, so that the ropes 2 become nervous.

[0003] When winding is started, the vibration caused by the rotation of the oyster removing machine 5 to scrape off the oysters 1 attached to the rope 2 is transmitted to the tensioned rope 2 and the guide reel 3
It is transmitted to itself. Therefore the rope 2
Oysters 1 attached to the water often fall off and fall into the sea.

Therefore, conventionally, the structure of the guide reel 3 is
As shown in FIG. 2, a concave portion 11 is formed on a peripheral surface by a partition plate 12 so that dropped oysters can be collected, and a collecting net is provided on the seabed at the dropped position. Oysters and the like overflow immediately, and oysters that have fallen off due to the ocean currents do not fall to the position of the net. Therefore, complete sheltering cannot be achieved, and the collection rate is extremely low at present.

[0005] As an improvement, there is an improvement in which a vibration caused by a tightly attached rope is absorbed by a reel itself so as to prevent falling of marine products such as oysters attached to the rope to be pulled up.

[0006] However, although a slight improvement is seen, complete recovery cannot be achieved if a large amount of oysters adhere to the recovery rope.

[0007]

SUMMARY OF THE INVENTION In view of the foregoing, it is a primary object of the present invention to provide a marine product recovery apparatus which can provide a complete recovery rate by providing a net between a recovery reel and a sea surface. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 4, FIG. 5 and FIG. 6 are a plan view, a front view and a rear view of a marine product recovery apparatus showing one embodiment of the present invention. Reference numeral 10 denotes a frame, in which a linear portion 11a is added from a semicircular shape or a semicircular shape on a plane, a plurality of vertical streaks for integrally connecting the linear portions are provided, and the diameter is reduced to a reinforcing portion which is turned horizontally. The lower part is integrated by welding or the like.

The upper frame 11 is formed in a semicircular shape on a plane or in a shape obtained by adding a linear portion from a semicircle. The length of the vertical frame 12 is basically five, and as shown in the figure, a vertical frame is bent from the outside to the inside, and a space is provided between the inside and the outside. It is formed to open. The distance between the inside and the outside can be changed as appropriate depending on the amount of marine products to be recovered, but for oysters,
The recovery weight can be set to a size that can secure a volume that can be recovered by a weight of about 30 kg that can be lifted by one person. The inside angle α is preferably about 30 ° to 70 °. A lower frame 14 is connected to an inner end of each vertical stripe frame 12 so as to have a circular shape on a plane in order to secure a space in which seafood can move up and down. The lower frame 14 has a shape in which a part of the lower rope 14 is partially cut off so that the recovery rope 2 to which the marine product adheres does not come into contact when the frame 10 is rotated.

A falling guide sheet 20 is attached to the lower frame 14 of the frame 10. A hole through which a binding string can be passed is formed at a connection portion between the sheet 20 and the lower frame 14, and the sheet 20 is fixedly integrated with the lower frame 14 with the binding string. Then, in order to secure the expected diameter of the marine products to be recovered, the upper side is deflated in a truncated cone shape, and even when the marine products are large, a cut is made radially from the upper end to avoid contact falling off.
0a is provided. The cuts 20a are for coping with the massive attachment of a part of a huge marine product to the rope 2, and the number and length of the cuts are adjusted by the elasticity and rigidity of the sheet 20. Since the slices 22 themselves formed by the cuts 20a have elasticity and resilience, the falling seafood rarely falls into the sea after coming into contact with the slices 22. Sheet 2
0 is provided with a notch like the lower frame 14. The material of the sheet 20 is preferably made of polypropylene having a thickness of about 2 to 3 mm, because it can withstand the weight of marine products such as oysters, has good slippage, and has good corrosion resistance. Although rubber may be used, a slight frictional resistance occurs.

A net 30 is attached to the frame 10 to secure the dropped seafood. The net 30 may be a fishing net, but the rigidity may be increased because the synthetic resin net has a large cross section.

When the frame 10 is mounted on the hull, the height of the frame 10 is adjusted. That is, as shown in FIGS. 6 and 7, the vertical bar 15 is provided on the left and right end sides so as to be movable with respect to the support member 40, and the vertical bar support portion 41 of the support member 40 penetrating the vertical bar 15 is screwed. 42 are provided,
After the frame 10 is installed at an optimum position by the screws 42, the frame 10 is fixed. In this case, the screw contact side of the vertical bar 15 is made flat so that the screw 42 is securely tightened and the vertical bar 15 is prevented from rotating.

The support member 40 is formed so that it can be adjusted to protrude outward with respect to the hull. Column support 4
Reference numeral 1 denotes a bar 43 protruding in the horizontal direction, and the bar 43 is fixed by a screw 45 provided on a sleeve 44 fitted with the bar 43. The sleeve body 44 is further formed vertically and is rotatably attached to the main body 46. The main body 46 and a shaft 47 formed vertically from one end of the sleeve body 44 are fitted. In this case, the screw contact side of the rod 43 is made flat so that the screw 45 is securely tightened and the rod 43 is prevented from rotating.

The support member 40 is configured to be rotatable upward with respect to the hull 60. That is, the support member 40 is normally attached to the hull 60 by the fastening screw 48, but after being attached, the support member 40 is pivotally displaced upward about the upper end of the hull 60 together with the frame 10 for harvesting the dropped seafood. In order to be able to do so, it is attached via a hinge 49.

Next, how to use the apparatus of the present invention will be described. First, the support member 40 is attached to the hull 60, and the lower end of the frame 10 is adjusted to approach the vicinity of the sea surface and fixed with the screws 42. When brought close to the vicinity of the sea surface, the vibration damping becomes farther from vibration source and Do Ri, can ensure dropping collection of recovered marine products emerged from the sea. Next, the rod-shaped body 4 is adjusted so that the center of the culture rope 2 and the center of the frame 10 coincide with each other.
3 is adjusted to extend and retract, and the front and rear positions of the frame 10 are moved and fixed with the adjusting screws 45.

When the installation is completed, one culture rope 2 is pulled up from the culture raft, guided to the center position of the sheet 20 from the cutout portion 22 of the falling-off guidance sheet 20, and the leading end of the rope 2 is wound via the reel 3. It is hung on the take-up machine 4 and winding is started.

When the winding starts, a minute vibration is transmitted to the rope 2 and the guide reel 3, and when the attached seafood reaches the upper surface of the reel 3, a part of the seafood is dropped off. The fallen marine product hits the falling-off guide sheet 20, but enters the net 30 via the guide sheet 20, or directly enters the net 30 and can be collected. In this case, since the hole diameter of the guide sheet 20 is small,
Very few fall into the sea from this area. Usually, the total amount of dropout seems to be about 10 to 20% of the recovery amount. If the wind is strong and the sea is rough, the shedding will be even greater.

When a predetermined amount of marine products in the collecting device is deposited in the net 30, the marine products are collected in the ship. First one screw 45
Is loosened, as shown in FIG.
4 can be swiveled about the shaft portion 47, so that the recovery device is dragged to the rim of the boat on the other side, and as shown in FIG. , It is possible to guide the collection device around the hinge 49 into the cabin and take in the recovered seafood into the hold. FIG. 8 omits the illustration of the net 30 for convenience.

FIG. 9 shows an example of a split arm device installed when a crane or the like is not equipped like a small boat. Reference numeral 71 denotes a column planted on the hull, which is provided with a divided arm 72 protruding in the horizontal direction at the head and rotatably provided. At the intermediate position of the split arm 72, the pins are connected so as to be able to turn horizontally around the pin 73.
An anchor 74 for supporting the frame 10, for example, a non-corrosive wire, a chain, or a synthetic rope is suspended from the tip of the split arm 72.

The entire length of the split arm 72 is set to L, and in actual use, to shorten it to Lm, a pin 7 provided at an intermediate portion is used.
It is used by being bent so as to form a flat shape around 3. The split arm 72 can be made of a material such as non-rusting aluminum. Therefore, depending on the amount of protrusion outside the frame 10, the tip position of the split arm 72 is
It will follow 0. A mounting portion 75 of the lower end of the wire 74 to the frame 10 has a screwing structure according to the vertical movement of the frame 10.

With this configuration, an excessive load on the support member 40 of the frame 10 due to the accumulation of marine products can be prevented, and the collection operation is facilitated.

The split arm device 70 can be driven electrically or hydraulically / pneumatically. The power unit is pillar 7
By installing the split arm 72 so as to be horizontally swiveled in 1, it is possible to avoid the manual operation of moving the frame 10 from the collection installation position to the hull. Therefore, it is possible to avoid dangerous work such as a fishing worker getting off the rim of the boat and picking up the frame 10. The power hoist is divided arm 7
By being provided at the front end position of 2, the power winding of the wire 74 or the like can be made possible, which is suitable for a fishing boat not equipped with a winch or the like.

By the way, the fall of the harvested seafood often falls mainly on the sea area side of the rope 2 (the opposite side of the hull). Therefore, even if the drop-off guide sheet 20 and the net 30 as shown in FIG. 4 are provided only on the sea area side with the plane rope 2 as the center, and even if the net is as shown in FIG. Can be recovered.

[0039]

As described above, according to the present invention, a net is provided between the collecting reel and the sea surface, so that a complete collection rate can be achieved.

Further, the recovered marine products can be recovered at once using a crane or the like.

In addition, a sheet in which the falling-off guide sheet has fallen in the vicinity of the collecting rope can be collected.

In addition, the collection frame that has become heavy during collection can be turned via a hinge, and the collection device can be guided into the hold by a crane or the like.

Also, the turning of the heavy frame can be lightened by power, and the work of fishermen can be reduced.
