It is completely isolated by a not-shown separator or the like between the acid treatment mechanism 25 and each mechanism and the like.

Next, a method for treating the cuttings of laver according to the present embodiment will be described.

First, only one front guide member 7 is extended forward, and the other pair of rear guide members 9 is contracted so as to have the shortest length, and then the hull 4 is stretched with the seaweed net 1. The power propulsion mechanism 5 is driven from the installation extension direction to allow it to enter by self-propelling force, and the nose net 1 is continuously scooped up from the sea surface by the front guide member 7 whose tip is immersed in the sea. The nori net 1 is guided to the rear part of the hull along the upper guide member 8. At this time, the seaweed net 1 is positioned along the upper guide member 8 by manipulating the seaweed net 1 located above the hull 4 while visually observing the seaweed net 1 from the steering room 49 provided at the tail end of the hull 4. Good guidance to the rear of the hull. Further, when the rear end of the seaweed net 1 reaches the rear end of the rear guide member 9 in a contracted state, the hook 18 attached to the rear end of the pipe 14d is hooked on the side rope of the seaweed net 1 to form the seaweed. Each pipe 1 of the rear guide member 9 according to the relative movement of the net 1 to the rear side.
4d, 14c, 14b are pulled out to the rear in order. When each of the pipes 14d, 14c, 14b is extended to the longest,
Excessive force is applied to the hook 18, the click mechanism 20 is disengaged, and the hook 18 rotates about the shaft 19 to release the engagement between the hook 18 and the seaweed net 1. After that, seaweed net 1
Only the rear part of the rear guide member 9 is returned to the sea surface.

In the meantime, the leaf cuttings 21 of the seaweed hanging down from the seaweed net 1 moving along the front guide member 7 are removed.
, The mowing of the laver net 1 after the mowing is performed by the acid processing mechanism 25, and then the relative movement to the rear end of the rear guide member 9. In the meantime, the acid treatment agent is sufficiently penetrated into the laver cells and sterilizes various germs attached to the leaves.

Since the acid treatment by the acid treatment mechanism 25 in the present embodiment is immediately after the mowing by the mowing mechanism 21, the seaweed net 1 is in a draining state and the acid treatment pipe 26
The acid treatment liquid sprayed from each of the spray holes 27 is evenly applied over the entire width of the seaweed net 1, so that processing unevenness does not occur. In addition, since the acid treatment is performed immediately after cutting, the acid treatment effect is extremely high, and
Since the pH of the acid treatment agent is kept at a predetermined value by the sensor 32, the acid agent supply system 33, and the diluent supply system 34, good acid treatment can always be performed.

Further, in the present embodiment, since the permeation rate of the acid treatment agent into the cells of the seaweed is increased by the permeation promoting mechanism 41, the seaweed net 1 moves from the rear end of the rear guide member 9 to the seawater. Even if the time until it is re-immersed is further shortened, a sufficient acid treatment effect will be exhibited. In addition, the ultrasonic oscillator 47 has a cleaning action and a sterilization mechanism 4.
The bactericidal action of No. 8 further enhances the acid treatment effect.

As described above, in the present embodiment, by simply propelling the hull 4, the seaweed net 1 stretched in seawater by the front guide member 7 is pulled up on the ship and the seaweed is automatically cut. , More effective acid treatment can be automatically applied and spread again in seawater, improving the yield of seaweed and promoting healthy growth of seaweed, thus improving work efficiency. It is possible to improve and save labor and labor. In addition, the steering room 49 is provided at the tail end of the hull 4, and the seaweed net 1 can be seen while visually observing the state of the seaweed net 1 guided by the front guide member 7 and the upper guide member 8 of the guide member 6. It is possible to operate the ship so that it does not shift, and it is also possible to visually operate the seaweed net 1 guided by the rear guide member 9 of the guide member 6 from the vicinity.

Further, in the present embodiment, by rewinding the wire 17b by the motor 17, the pipes 14b, 14c, 14d of the rear guide member 9 can be housed in the outermost pipe 14a for safety. In addition, since the maximum extension length of each of the pipes 14b, 14c, 14d can be freely made longer than the length of the hull 4, the acid treatment and the like can be performed reliably and effectively.

Further, in the present embodiment, since the cutting mechanism 21 and the acid treatment mechanism 25 are provided, only one of the mechanisms is operated as necessary to remove the seaweed or the seaweed. It can be used as a net acid treatment vessel, and one vessel can perform three roles, which makes it highly useful.

In the above embodiment, the acid treatment liquid is sprayed onto the laver net 1 as the acid treatment mechanism 25. However, for example, like the permeation promoting mechanism 41, the laver net 1 is immersed in the acid treatment liquid. Alternatively, the laver net 1 may be coated with the acid treatment liquid by a roller.

Further, the present invention is not limited to the above embodiment, but can be modified as necessary.

As described above, according to the acid-treated boat for laver nets of the present invention, the acid-treatment of the laver nets can be automatically and extremely efficiently performed by using the ship, thereby saving labor. , Labor can be saved. In particular, since the steering room is provided at the rear of the hull, it is possible to steer the seaweed while visually observing the seaweed net above the hull guided by the guide member, and the seaweed net can be properly guided to the proper position. .

Further, according to the acid-treating vessel for cutting seaweed of the present invention, the vessel can be used to automatically and efficiently cut the seaweed, and the acid treatment is also carried out automatically and extremely efficiently. It is possible to achieve excellent effects such as saving labor and saving labor. In particular, since the steering room is provided at the rear of the hull, it is possible to steer the seaweed while visually observing the seaweed net above the hull guided by the guide member, and the seaweed net can be properly guided to the proper position. .
