The operating cable 54 is longer than the mutual distance between the metal fittings 67 and 68 at both ends, and is slightly loosened. Although not shown, the collecting tool 53 is provided with an openable/closeable gripper for grasping kelp at the lower end, and a lever for opening/closing this gripper is provided at an appropriate location in the middle. Note that the configuration of the sampling tool 53 itself is well known, so a detailed explanation will be omitted. Further, a foot-operated switch 69 is connected to the winch 51. This switch 69 is installed on the floor to the right of the seat 23 in the storage space 22 and is connected to the generator 39. Cable 5 for lifting winch 51
The sampling tool 53 suspended from the vessel A is put into the sea through the well 12 of the sampling vessel A, and is raised and lowered by operating the winch 51 with a foot-operated switch 69.

When the collection vessel A is traveling, the collection tool 53 is pulled up from the well 12 onto the hull 10 and placed in the storage space 2.
Place it in a suitable place such as 2. At this time, the collection tool 53 may remain connected to the lifting cable 52 or may be separated from the lifting cable 52.
Further, the main body 50 may be left standing on the hull 10, or the mounting portion 55b may be removed from the support tubes 63, 64, the support column 55 may be folded, and the main body 50 may be left lying in an appropriate location such as the storage space 22.

When performing sampling work, if the main body 50 of the sampling device B has been removed, it is fixed to the hull 10. Furthermore, if the collecting tool 53 has been separated from the lifting rope 52, these are connected and the collecting tool 53 is put into the sea through the well 12, completing preparations for the collecting work.

When the preparations are completed, as shown in FIG. 1, the worker sits astride the seat 23, presses his face against the eye mask 29, and looks into the sea. Then, use the control stick 4 with your left hand.
While finely adjusting the position of the boat by operating the 0, the user operates the collection tool 53 inserted into the sea through the well 12 with his right hand to grasp the root of the kelp. For example, the control stick 40 is provided with a switch at its tip for switching the rotational direction of the propeller section 37, and the direction of the propulsive force by the propeller section 37 is controlled by this switch and the direction in which the control stick 40 is tilted. The magnitude of the propulsive force is controlled by the magnitude of the tilt of the control stick 40. In addition, without providing a switch for switching the rotation direction of the propeller section 37,
It is also possible to control the direction of the propulsive force only by tilting the control stick 40. At the same time, by operating the foot-operated switch 69, the collection tool 53 can be
You can grab kelp by moving it up and down appropriately.

Once the roots of the kelp are grasped with the collecting tool 53, the foot-operated switch 69 is operated to raise the collecting tool 53. As a result, the kelp is pulled out, and the collection tool 53 that grips the kelp is pulled up through the well 12 and above it, as shown by the chain line in FIG. Once the lower end of the sampling tool 53 has been pulled up to just above the well 12, as shown by the solid line in FIG. By lifting the kelp diagonally upward, the kelp caught with the collection tool 53 is placed in the storage space 2.
2 Pull up. Then, the kelp is released from the collecting tool 53, the collecting tool 53 is put back into the sea, and the same operation is continued. In addition, the kelp pulling work will be carried out during the second stage.
You can do this while sitting on the seat 23 as shown in the figure, or you can do it by standing up on the spot.

In this way, if it is necessary to pull up kelp, you can simply stand up on the spot and work through the well 12 formed on the hull centerline while sitting on the seat 23, making the work safer. And easy. Since the eye mask 29 is attached within the well portion 12 by the handle 26,
There is no need to hold it in your mouth, and the pain is minimal even when working continuously for long periods of time. A foot-operated switch 69 that operates the winch 51 for raising and lowering the collection tool 53
is provided on the floor near the seat 23, and the control stick 40 of the outboard motor 33 for fine movement is provided near the seat 23.
It is easy for one person to perform the operation. In addition, since the collector can also operate the outboard motor 33, he or she can finely adjust the position of the boat according to his or her intention, which is efficient. Also, using the sampling device B, the sampling tool 5
The kelp caught in step 3 can be easily and safely pulled onto the ship. Therefore, the kelp collection work was
It can be done safely, easily and efficiently by humans.

When the collection work is completed, place the collection tool 53 pulled up on board the ship in an appropriate place such as the storage space 22, and if necessary, move the collection tool 53 onto the lifting cable 52.
In addition, the main body 50 of the sampling device B is removed from the hull 10 and placed in an appropriate location. On the other hand, if necessary, after removing the eye mask 29 and rotating the seat 23 to the retracted position,
Pull it upward from the cylindrical portion 34 to remove it. On the other hand, after rotating the bottom cover 19 of the well part 12 to the closed position and inserting and fixing the bolt 41 into the recess 42 at the bottom of the peripheral wall 14, the top cover 16 of the well part 12 is rotated to the closed position. , insert the bolts 43 into these fixing fittings 18 and fix them. Then, in this state, the collection vessel is sailed using the outboard motor 11 for sailing.

The reason why the bottom cover 19 is provided in the well portion 12 and is closed during cruising is to reduce resistance during cruising, but the bottom cover may not be provided. The upper lid 16 does not necessarily need to be closed during navigation, and the upper lid may not be provided.

Note that conventionally, a battery has been used to drive the outboard motor for fine movement. For this reason, long-term use, ie, collection work, was impossible, and it was necessary to carry a heavy battery ashore to charge it, making the work difficult. In contrast, in the above embodiment, a small generator 39 is installed to drive the outboard motor 33 for fine movement, so it can be used for a long time only by supplying fuel, and it can be used for charging. Work is easier because there is no need to move heavy batteries.

The structure and combination of the top cover and bottom cover of the well portion 12 are not limited to those of the above embodiments, and can be modified as appropriate. The method of attaching the eye mask to the well portion 12 is not limited to that of the above embodiment, and can be changed as appropriate. In addition, in the above embodiment, the control stick 40 is used to operate the outboard motor 33 for fine movement with one hand. However, a foot-operated switch is installed instead.
The outboard motor 33 for fine movement may also be operated by foot. Further, the configuration of the main body 50 of the kelp collecting device B is not limited to that of the above embodiment, and can be modified as appropriate. For example, reinforcing legs or the like may be provided at the bottom of the support column 55 to which the winch 51 is attached, and the support leg 55 may be fixed to the hull 10. Further, the winch 51 may be attached to an appropriate position on the hull 10.

Effects of the invention According to the kelp collecting device of this invention, as mentioned above, the work of collecting kelp, especially the pulling work, is facilitated.
It can be done safely and efficiently.
