Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recovering lost products when aquaculture marine products such as aquaculture oysters, aquaculture scallops and aquaculture algae are pulled up.

[0002]

2. Description of the Related Art Conventionally, for harvesting aquaculture marine products such as oysters, generally, a guide reel mounted on one port of the recovery ship and a rope winding machine (hydraulic and electric) provided on the other port.
As a result, the rope with oysters attached is pulled up from the sea. That is, as shown in FIG. 1, the rope 2 having the oysters 1 attached thereto is first hung on the guide reel 3, and the tip of the rope 2 is further wound by the winding machine 4. in this case,
One of the ropes 2 is wound up, and the other one is attached with oysters 1 and the like, and is heavy, so that the rope 2 becomes tense.

When winding is started, the oyster removing machine 5 rotates and the vibration caused by scraping off the oysters 1 attached to the rope 2 is transmitted to the tensioned rope 2 and the guide reel 3
It is also transmitted to itself. Therefore, the vibration causes the rope 2
The oysters 1 attached to the fish often fall off and fall into the sea.

Therefore, the structure of the guide reel 3 is conventionally changed to
As shown in FIG. 2, the partition plate 12 forms a recessed portion 11 on the peripheral surface so that the dropped oysters can be collected, and a net for collection is put on the seabed at the falling position. The oysters soon overflow, and the oysters that have fallen under the influence of the ocean current do not fall to the position of the net, so complete fall prevention cannot be achieved and the recovery rate is extremely low.

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

However, although some improvement can be seen, a complete recovery cannot be achieved when a large amount of oysters adhere to the recovery rope.

[0007]

SUMMARY OF THE INVENTION In view of the above points, the present invention has as its main object to propose a marine product collecting apparatus which has a net body between the collecting reel and the sea surface and can achieve a complete collecting rate. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below 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 collecting apparatus showing an embodiment of the present invention. Reference numeral 10 denotes a frame, which has a semi-circular shape or a semi-circular shape on a plane and is provided with a straight line portion 11a. 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 in which a straight line portion is added to the semicircle. There are basically five vertical stirrup frames 12, 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. Formed to open. The distance between the inside and the outside can be changed appropriately depending on the amount of seafood to be collected, but for oysters,
The recovery weight can be set to a size that can secure a recoverable volume of about 30 kg which can be lifted by one person. The inner angle α is preferably about 30 ° to 70 °. A lower frame 14 is connected to the inner end of each vertical streak frame 12 so as to have a circular shape in plan view, in order to secure a space in which marine products can move up and down. The lower frame 14 has a shape that is partially cut off so that the recovery rope 2 having marine products attached thereto does not come into contact with the lower frame 14 when it is recovered by the turning operation of the frame 10.

A lowering guide sheet 20 is attached to the lower frame 14 of the frame 10. A hole through which a binding cord can pass is formed at a connection portion of the sheet 20 with the lower frame 14, and the binding frame is fixedly integrated with the lower frame 14. Then, in order to secure the expected diameter of the seafood to be recovered, the upper part is shrunk in a truncated cone shape, and even when the seafood is large, a radial cut is made from the upper end to avoid contact loss.
0a is provided. The cuts 20a are for accommodating even a large amount of massive marine product deposits on the rope 2, and the number and length of the cuts are adjusted by the elasticity and hardness of the sheet 20. Since the slice 22 itself generated by the notch 20a has elasticity and resilience, the fallen seafood is unlikely to fall into the sea after coming into contact with the slice 22. Sheet 2
No. 0 has a cutout portion as in the lower frame 14. The material of the sheet 20 is preferably made of polypropylene and having a thickness of about 2 to 3 mm because it can withstand the weight of marine products such as oysters, has good slipperiness, and has good corrosion resistance. Rubber may be used, but some frictional resistance occurs.

A net 30 is attached to the frame 10 in order to secure the lost seafood. The net 30 may be a fishing net, but since the synthetic resin net has a large cross section, the rigidity may be enhanced.

The frame 10 is constructed so that its height can be adjusted when it is attached to the berth. That is, as shown in FIGS. 6 and 7, the vertical bars 15 are 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 which penetrates the vertical bar 15 is screwed. 42 is provided,
After the frame 10 is installed at the optimum position with the screw 42, it is fixed. In this case, the screw 42 is securely tightened, and the screw contact side of the vertical bar 15 is made flat so as to prevent the vertical bar 15 from rotating.

The support member 40 is formed so that it can be adjusted so as to project outward with respect to the ship berth. Vertical bar support 4
1, a bar-shaped body 43 protruding in the horizontal direction is formed, and the bar-shaped body 43 is fixed by a screw 45 provided on a sleeve body 44 fitted with the bar-shaped body 43. The sleeve body 44 is further formed in a vertical shape and is rotatably attached to the main body portion 46. The main body portion 46 and the shaft portion 47 formed vertically from one end of the sleeve body 44 are fitted together. In this case, the screw contact side of the rod-shaped body 43 is made flat so that the screw 45 is securely tightened and the rotation of the rod-shaped body 43 is prevented.

The support member 40 is constructed so as to be rotatable upward with respect to the boat edge 60. That is, the support member 40 is normally attached to the berth 60 by the tightening screw 48, but after being attached, the support member 40 is pivotally displaced upward together with the frame 10 around the upper end of the berth 60 for harvesting the lost seafood. It is attached via a hinge 49 so as to be possible.

Next, a method of using the device of the present invention will be described. First, the support member 40 is attached to the boat edge 60, the lower end of the frame 10 is adjusted so as to approach the vicinity of the sea surface, and then fixed with the screw 42. When both are approached to near the sea surface, they are farther from the seismic source and vibration-damped. By comparing the two, it is possible to ensure the drop-out recovery of the recovered marine products that floated from the sea. Next, the rod-shaped body 43 is expanded and contracted so that the center of the aquaculture rope 2 and the center of the frame 10 coincide with each other, and the front and rear positions of the frame 10 are moved and fixed by the adjusting screw 45.

When the installation is completed, one aquaculture rope 2 is pulled up from the aquaculture raft, guided from the cutout portion 22 of the dropout guide sheet 20 to the center position of the sheet 20 and the tip of the rope 2 is wound through the reel 3. It is hung on the winding machine 4 and winding is started.

When the winding is started, a slight vibration is transmitted to the rope 2 and the guide reel 3, and when the attached marine products reach the upper surface position of the reel 3, they are partly dropped. The fallen seafood hits the drop-off guide sheet 20, but enters the net body 30 through the guide sheet 20 or directly enters the net body 30 and can be collected. In this case, since the hole diameter of the guide sheet 20 is small,
Very few fall into this area from the sea. It seems that the total dropout amount is usually about 10 to 20% of the recovered amount. When the wind is strong and the sea surface is rough, the dropout amount is even greater.

When a predetermined amount of marine products in the collecting device are accumulated in the net 30, the marine products are collected in the ship. First one screw 45
Loosen the other sleeve body 4 as shown in FIG.
Since it can swivel around the shaft portion 47 of the No. 4, the recovery device is pulled to the other side on the other side, and as shown in FIG. By lifting up, the recovery device can be guided around the hinge 49 into the cabin and the recovered marine products can be taken into the hold. Note that, in FIG. 8, the net body 30 is not shown for convenience.

FIG. 9 shows an example of a split arm device installed when a crane or the like is not equipped as in a small boat. Reference numeral 71 designates a support column which is planted at the berth, which is provided with a split arm 72 projecting horizontally from the head so as to be rotatable. It is pin-coupled at an intermediate position of the split arm 72 so as to be horizontally rotatable around the pin 73.
At the tip of the split arm 72, a locking body 74 for supporting the frame 10, for example, an antirust wire, a chain or a synthetic fiber rope is suspended.

The total length of the split arm 72 is L, and in actual use it is shortened to Lm.
It is used by being bent so as to have a flat V shape centering on 3. The split arm 72 can be made of a non-rusting material such as aluminum. Therefore, depending on how much the frame 10 projects outside, the tip position of the split arm 72 is set to the frame 1
It will follow zero. An attachment portion 75 at the lower end of the wire 74 and the like to the frame 10 has a screwing structure according to the vertical movement of the frame 10.

With such a structure, it is possible to prevent an excessive load on the support member 40 of the frame 10 due to the accumulation of marine products, and the collection work becomes easy.

The split arm device 70 can be driven electrically or hydraulically / pneumatically. The power plant is prop 7.
By installing the split arm 72 so as to horizontally swivel at 1, the manual operation of moving the frame 10 from the collection installation position to the berth can be avoided. Therefore, it is possible to avoid a dangerous work such as a fishing worker getting out of the berth and pulling the frame 10. The power hoisting device is a split arm 7.
By being provided at the distal end position of 2, the power of the wire 74 can be hoisted, which is suitable for a fishing boat not equipped with a winch or the like.

By the way, most of the harvested marine products fall off mainly on the sea side of the rope 2 (on the side opposite to the berth). Therefore, even if the dropout guide sheet 20 and the net body 30 as shown in FIG. 4 are provided only on the side of the sea area with the plane rope 2 as the center and the net body as shown in FIG. Will be collected.

[0039]

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

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

It is also possible to collect the drop-out guide sheet that has fallen near the recovery rope.

Further, during the recovery, the heavy recovery frame can be swung through the hinge, and the recovery device can be guided into the hold by a crane or the like.

Further, the heavy frame can be lightly turned by turning, and the work of the fisherman can be reduced.
