Is equipped with a power propulsion mechanism 13 on the hull 12, and a pipe-shaped guide member 14 is provided on the upper part of the hull 12. The guide member 14 is divided into a front guide member 15, an upper guide member 16 and a rear guide member 17. The front guide member 15 is formed in a U-shape in a plan view. The U-shaped curved tip is submerged in the sea at a certain inclination from the bow, and the other end is erected on the deck by a downward leg 18. In addition, the base portion of the front guide member 15 is detachably and rotatably attached to the upper guide member 16 by a bolt 19. In addition, the upper guide member 16
Is formed by two pipes arranged above the left and right sides of the hull 12 in parallel with the axial direction of the hull 12,
The two pipes are connected to each other by several crosspieces 20 which are orthogonal to the axial direction of the hull 12, and the legs 21
It is fixed to the hull 12 by.

The upper guide member 16 has a curve or a straight line continuous with the front guide member 15 so that the seaweed net 1 scooped up by the front guide member 15 can be smoothly guided to the rear of the hull. Configured to form.

On the left and right sides of the rear end of the upper guide member 16, there are fixed rear guide members 17 which are extendable and contractible in the longitudinal direction as shown in FIG. The rear guide member 17 is formed by a plurality of (four in the present embodiment) pipes 22a, 22b, 22c, 22d having a gradually smaller diameter so as to be telescopic in a coaxial manner so as to be expandable. The pipe 22a is fixed to the rear end of the upper guide member 16. A nut body 25 is fixed to the lower surfaces of the tips of the three inner pipes 22b, 22c and 22d so that the upper end of a rigid rod 24 having a float 23 fixed to the lower end thereof can be screwed on and off.

It is preferable to set the height slightly higher than the traveling position on 4, and the height of the upper end of the column is preferably higher than this.

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

FIG. 10 is an explanatory view showing the spread state of the seaweed net, and FIG. 11 is an explanatory view showing the cutting of the seaweed and the acid treatment of the seaweed net.

In FIG. 10, 1a, 1b, 1c, 1d
Is a seaweed net, which is stretched in parallel with the pillar 4 in the seaweed farm. Then, the acid treatment liquid is put into the acid treatment liquid tank 38 of the seaweed cutting acid treatment ship 59.

To cut off the seaweed, the acid treatment is performed by first extending only one front guide member 15 and contracting the other pair of rear guide members 17 to the shortest length. The power propulsion mechanism 13 is operated from the right end direction in FIG. 10, which is one end portion of the seaweed net 1a, to allow the hull 12 to enter by self-propulsion force, and the cutting mechanism 31 and the acid treatment mechanism installed in the steering room 58. 35, the ultrasonic oscillator 56 and the sterilization mechanism 57 are operated by a control unit that manages commands. Then, the nori net 1a is continuously scooped from the sea surface by the front guide member 15 whose tip is immersed in the sea, and the nori net 1a is guided toward the stern direction along the upper guide member 16 as the ship propels itself. . At this time, the floating ring 9 connected to the seaweed net 1a via the hanging rope 8 is automatically raised toward the upper side of the column 4 whose maximum movement position is the length of the restraining rope 11 as the ship propels itself. Moving.

Further, when the tip of the seaweed net 1a reaches the rear end of the rear guide member 17 in the contracted state, the hook 26 attached to the rear end of the pipe 22d is hooked on the edge rope 2 of the seaweed net 1a. , The respective pipes 22d, 22c, 22 of the rear guide member 17 with the relative movement of the seaweed net 1a to the rear.
Pull out b in order. Each pipe 22d, 2
When 2c and 22b are extended to the maximum length, an excessive force is applied to the hook 26, the click mechanism 28 is disengaged, and the hook 26 is released.
Rotates around the shaft 27, and the hook 26 and the seaweed net 1
The engagement with a is released. After that, only the seaweed net 1a moves backward and is returned to the sea surface from the rear end of the rear guide member 17. At this time, the floating ring 9 connected to the seaweed net 1a via the hanging rope 8 is automatically moved downward toward the sea surface portion as the ship propels itself.

In the meantime, the leaf bodies of the seaweed hanging from the seaweed net 1a moving along the front guide member 15 are continuously cut and harvested by the cutting mechanism 31 and stored in the storage portion 34 of the hull 12, and subsequently. Acid treatment is applied to the seaweed net 1a after cutting by the acid treatment mechanism 35, and then the acid treatment agent is sufficiently permeated into the cells of the seaweed while moving relatively to the rear end of the rear guide member 17, and the leaf body is also treated. Sterilize adhering bacteria.

The liquid 41 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 the pH of the acid treatment agent is adjusted to a predetermined value by the pH sensor 42, the acid agent supply system 43, and the diluent supply system 44. Since it can be held, good acid treatment can always be performed.

Further, in this embodiment, since the permeation rate of the acid treatment agent into the cells of seaweed is increased by the permeation promoting mechanism 50, the seaweed net 1 moves from the rear end of the rear guide member 17 to seawater. Even if the time until re-input is further shortened, a sufficient acid treatment effect can be exhibited. Also,
The acid treatment effect is further enhanced by the cleaning action and the sterilizing action by the ultrasonic transmitter 56.

As described above, in this embodiment, the hull 12
The seaweed net 1 stretched on the surface of the sea by the front guide member 15 is scooped up on the ship by simply propelling the seaweed, the seaweed is automatically mowed, and more effective acid treatment is automatically applied. , Can be expanded to the sea surface again,
It is possible to improve the harvest rate of seaweed, promote healthy growth of seaweed, improve work efficiency, and save labor and labor.

Further, in this embodiment, the motor 30
