BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seaweed harvesting boat for cutting seaweed cultivated by a net and a seaweed net guiding mechanism used in the seaweed harvesting boat.

[0002]

2. Description of the Related Art Nori is generally cultivated in a net stretched over the sea surface, and after a certain period of time, the nori grown on the net is harvested. When cutting seaweed, prepare a seaweed harvesting boat with a fixed seaweed net guide and unsecured corners. With this corner lowered about 1 m below the sea surface, the laver harvesting boat is sunk into the laver net, and the laver harvester installed under the laver net guide cuts the laver. Once the seaweed has been cut, the horns are lifted into the ship to hinder the running of the ship. By repeating such a process several tens of times a day, the seaweed cutting operation is completed.

[0003]

In the above-mentioned laver cutting work, the work of lowering the horn below the sea surface and the work of lifting the horn into the ship are all performed by the crew. This work is hard work due to the considerable weight of the horns, and working offshore in winter is especially challenging. Furthermore, it is a very dangerous operation because the ship shakes in the event of a wave and the scaffold is easily slipped by the cut seaweed.

Therefore, the present invention has been made to solve the above-mentioned problems, and can automatically move the corner, further reduce the number of crew members of the ship, and reduce the amount of seaweed. It is an object of the present invention to provide a seaweed reaping ship and seaweed net guiding mechanism that does not involve danger.

SUMMARY OF THE INVENTION A laver harvesting boat according to the present invention is for collecting laver cultured by a net stretched in the sea, and has a hull and a seaweed extending from a bow to a stern. A pair of fixed net guide members attached to the hull at a distance, a slider movably provided in the longitudinal direction on the hull, a movable net guide member rotatably connected to the slider, and a vicinity of the bow A supporting member for slidably supporting the movable net guide member from below, and a driving means for moving the slider.

When the driving means moves the slider in the bow direction, the movable net guide member pivots downward in contact with the support member, and the tip of the movable net guide member connects the undersea net to the fixed net guide member. Enter the sea to guide you to. In addition, in this specification, the "bow" refers to a portion located on the front side in the traveling direction. Therefore, in the case of harvesting by moving backward, the normal stern can be the bow.

[0007] In such a seaweed cutting boat, it is possible to cut the seaweed by moving the tip of the movable net guide member into the sea using a driving means before diving into the seaweed net, and advancing the boat in this state. it can. When the seaweed has been cut, the driving means moves the slider in the stern direction so that the movable net guide member can be returned into the ship. for that reason,
The movement of the movable net guide member can be automated, and the number of crew members can be reduced as compared with the related art. Further, since the driving means can be operated from the wheelhouse, safety is improved. In addition, even if the seaweed harvesting boat becomes large, the movable net guide member can be easily moved by enlarging the driving means.

A laver net guiding mechanism according to the present invention guides a net onto a fixed net guide member fixed on a laver harvesting boat in order to collect laver grown on a seaweed net on a laver harvesting boat. A movable net guide member rotatably connected to the slider, and a movable net guide member slidable from below in the vicinity of the bow. And a driving means for moving the slider.

When the driving means moves the slider in the bow direction, the movable net guide member pivots downward in contact with the support member, and the tip of the movable net guide member connects the undersea net to the fixed net guide member. Enter the sea to guide you to.

In the laver net guide mechanism thus constructed, the slider is moved in the bow direction using the driving means before the laver harvesting boat dives into the laver net, and the tip of the movable net guide member is put into the sea. If you move the ship forward in the squat state, you can easily dive under the net, and in this state you can cut the nori. Further, when the seaweed has been cut, the driving means can move the slider in the stern direction and return the movable net guide member to the inside of the ship. Therefore, the movable net guide member can be automatically moved, and not only does not require heavy labor but also the number of crew members can be reduced. Further, the driving means can be remotely operated from the wheelhouse, which is safe. Furthermore, even when the seaweed harvesting boat becomes large, the movable net guide member can be easily moved by enlarging the driving means.

Further, in the laver harvesting boat and the laver net guiding mechanism, it is preferable that the driving means linearly moves the slider when given a rotational movement.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, in a laver reaping boat 1 according to the present invention, a fixed net guide member 3 serving as a laver net guide is movable on a hull 2 floating on a sea surface 7 in the front-rear direction. A movable net guide member 5 as a corner, a support member 4 for supporting the movable net guide member from below, a rotary liner 6 as a slider for moving the movable net guide member 5, and a rotary cutter 8 are provided. I have. The rotary liner 6 has a rotating shaft 10 and a main shaft 1 as shown in FIG.
1 and a hydraulic motor 9. When the hydraulic motor 9 rotates the rotating shaft 10 in a certain direction, the rotary liner 6 moves in one direction along the main shaft 11, and the rotary liner 6 in which the hydraulic motor 9 rotates the rotating shaft 10 in the reverse direction moves along the main shaft 11 in the opposite direction. Move to Since the rotary liner 6 and the movable net guide member 5 are rotatably connected, when the rotary liner 6 moves in the bow direction, the movable net guide member 5 also moves in the bow direction. When the rotary liner 6 moves in the bow direction, the movable net guide member 5 rotates downward while being supported by the support member 4 and moves to the distal end thereof. Enters sea level 7. The movable net guide member 5, a rotary liner 6 as a slider, a hydraulic motor 9 as a driving means, a rotating shaft 10, and a main shaft 11 constitute a laver net guiding mechanism.

Next, a method for cutting seaweed using the seaweed cutting boat 1 will be described. As shown in FIGS. 3 and 4, first, the seaweed harvesting boat 1 has a seaweed net 10 provided between the buoys 30 in a state where the movable net guide member 5 is stored in the ship.
Approaches zero. In addition, the seaweed harvesting boat 1 has a thruster 21,
The vehicle includes a propeller 22 and a rudder 23.

Next, as shown in FIG. 5, the hydraulic motor 9 shown in FIG. 2 is rotated to move the movable net guide member 5 forward so that its tip enters the sea surface. At this time, it is preferable that the hydraulic motor 9 be automatically stopped by the limiter switch when the movable net guide member 5 is lowered to a predetermined position.

Next, as shown in FIG. 6, when the seaweed harvesting boat 1 is advanced, the seaweed net 100 moves rearward along the movable net guide member 5 and further moves in the stern direction along the fixed net guide member 3. I do. At this time, the seaweed 40 attached to the seaweed net 100 can be cut by rotating the rotary cutter 8. Further, by moving the seaweed reaping boat 1 forward, seaweed can be continuously cut.

When the seaweed has been cut, the hydraulic motor 9 is rotated in the reverse direction to move the movable net guide member 5 into the ship, as shown in FIG. In this state, the ship is turned to move to the vicinity of a different net, and the seaweed can be cut as shown in FIGS.

According to the above procedure, for example, when cutting the seaweed of 30 nets 100 having the dimensions shown in FIG.

[0019]

According to the present invention, it is possible to provide a seaweed reaping ship and a seaweed net guide mechanism which can operate the movable net guide member remotely from the wheelhouse and can safely work.

If the size of the seaweed harvesting boat is increased, the size of the movable net guide member is also increased. In this case, however, it is possible to cope only by increasing the size of the driving means.

Since the movable net guide member is automatically moved, the working time can be reduced and the number of personnel can be reduced.

Since the movable net guide member is supported by the support member and the slider, the movable net guide member is less likely to vibrate and can be prevented from slipping off.

[0023] Even if the size or the moving distance of the movable net guide member is increased, it can be dealt with by changing the size of the driving means.

The safety is further enhanced by automatically stopping the raising and lowering of the movable net guide member by the limiter switch.
