[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seaweed, in which a seaweed net spread on a sea surface in a seaweed farm is subjected to chemical treatment such as cutting of seaweed and acid treatment of the seaweed alone or continuously. Regarding work boats.

[0002]

2. Description of the Related Art In general, seaweed cultivation is carried out by attaching a float to the seaweed net, floating it on the sea surface, spreading it and stopping it with an anchor, or using a mooring net with a plurality of stanchions erected in the sea. It is carried out by a strut system that moored and expanded the two, and the proper use of both types is determined by the location conditions of the farm.

In addition, in such seaweed aquaculture, seaweed cuttings from seaweed nets, and seaweed nets and floating substances such as dust adhere to the surface of seaweed that propagates on the seaweed nets, There is a factor that deteriorates the quality of seaweed, such as miscellaneous bacteria, and grows high-quality and healthy seaweed,
In order to improve the harvesting rate, chemical treatment work is performed twice or three times between cuttings of laver and acid treatment or nourishment of laver nets and laver that propagates in laver nets. Is being carried out.

FIG. 14 shows an example of floating nori culture, and is a plan view showing the spread state of a plurality of nori nets 1, 1.

Each of the long seaweed nets 1 has three extension ropes 3 and 3 which are extended in parallel between the extension bars 2 and 2 at the left and right ends.
The two columns are spread in parallel between the two. Further, an extension bar (not shown) is also provided in the middle of each nori net 1 in the longitudinal direction. Further, the forked rods 2 and 2 at the left and right ends are respectively connected to the forked ends 4a and 4a of the fixed rope 4, and the fixed ropes 4 are stretched in the left-right direction and are halfway. The float 5 is fixed, and the anchor 6 fixed to the end is anchored to the sea floor.

FIG. 15 shows still another example of floating nori culture, in which a fixed rope 8 called a side rope indicated by a thick solid line is stretched into a rectangular box larger than the nori net 1, Place the tip of the nori net 1 in the masu part with two reins 9,
It is connected by 9 and expanded. Extending rods 2 are provided at appropriate positions in the longitudinal direction of each seaweed net 1.

[0007]

Conventionally, the seaweed work boat 7 as shown in FIG. 14 is used for cutting the seaweed on the seaweed net 1 spread on the sea surface as shown in FIG.
I was doing it with. That is, the bow of the seaweed work boat 7 is advanced toward the fixed rope 4 at a right angle, and the seaweed work boat 7 is moved.
The seaweed cutting vessel 7 is cut under the fixed rope 4 and then the seaweed working ship 7 is moved in a direction perpendicular to the front-rear direction, that is, in the longitudinal direction of the seaweed net 1, while cutting the seaweed and treating the chemicals. It was It is not possible to advance the front and rear direction of the seaweed work boat 7 in line with the longitudinal direction of the seaweed net 1 because the fixed ropes 4 and 4 stretched on the extension of the seaweed net 1 in the longitudinal direction interfere with each other. Nori work boat 7 is Nori net 1
This is because it is not possible to proceed so as to dive under the seaweed net 1 by aligning the front-back direction with the longitudinal direction.

In addition, a mowing device and a chemical treatment device (both not shown) installed on the seaweed working ship 7 must be installed so that the seaweed net 1 moving in the width direction of the seaweed working ship 7 can pass through. Further, in the chemical treatment, it is more effective for the chemical treatment to leave the chemical-treated seaweed net 1 in the air for a predetermined time without immediately returning it to the sea surface. The passage time in the direction was very short, and the seaweed net 1 returned to the sea surface immediately after the chemical treatment, and a sufficient chemical treatment effect could not be expected. Therefore, in order to maximize the chemical treatment effect, it is necessary to dispose the chemical treatment device at the foremost portion in the moving direction in the width direction of the hull. Then, it is impossible to install the chemical treatment device and the mowing device side by side in the width direction of the seaweed work boat 7, and there is a disadvantage that the seaweed mowing and the chemical treatment cannot be performed continuously.

In the aquaculture system shown in FIG. 15,
The seaweed work boat 7 can travel in the longitudinal direction of the seaweed net 1, but the extension bar 2 provided in each seaweed net 1 is caught by the pillars provided in the seaweed work boat 7, and the seaweed work boat 7 advances. There was an inconvenience to prevent

A seaweed working ship for treating a seaweed net stretched on the sea surface with a fixed rope extending from the end of the seaweed net in the longitudinal direction, the scooping up the fixed rope from the sea surface, and on the hull. And a fixed rope guide member that guides the ship to the fixed rope when changing the traveling direction of the hull.
Nori work that includes a course-changing support that is used in combination, a nori net support that scoops the nori net from the sea surface into the hull and guides it to the stern, and a cutting device that cuts nori from the nori net. In the seaweed cutting method using a ship,
While advancing the seaweed work boat relative to the fixed rope in a direction orthogonal to its longitudinal direction, while scooping up the fixed rope, proceed to a position where it comes into contact with the course changing prop, and then rotate the hull. The fixed rope is guided through the fixed rope guide member into the hull so as to be parallel to the longitudinal direction of the hull, and then the hull is advanced parallel to the longitudinal direction of the fixed rope and the nori net to put the nori net into the hull. A method for cutting seaweed using a seaweed work boat, characterized in that the seaweed is cut from the seaweed net by the cutting device. 3. A seaweed working ship for treating a seaweed net stretched on the sea surface with a fixed rope extending from the end of the seaweed net in the longitudinal direction, the scooping up the fixed rope from the sea surface, and onboard the hull. And a fixed rope guide member that guides the ship to the fixed rope when changing the traveling direction of the hull.
It has a course-changing support that is used in combination, a nori net support that scoops the nori net from the sea surface into the hull and guides it to the stern, and a chemical treatment device that applies chemical treatment to the nori net. In a method for treating a seaweed net using a seaweed work boat, the seaweed work boat is advanced in a direction orthogonal to the longitudinal direction of the fixed rope to scoop up the fixed rope while contacting the course changing props. To the position, and then the hull is rotated to guide the fixed rope through the fixed rope guide member into the hull so as to be parallel to the longitudinal direction of the hull, and then the hull is fixed to the longitudinal direction of the fixed rope and the seaweed net. A method for treating a seaweed net using a seaweed work boat, characterized in that the seaweed net is guided in the hull by traveling in parallel with the direction and the seaweed net is subjected to a chemical treatment by the chemical treatment device.
