The seaweed reaper 5 is constructed as shown in FIGS. Ie deck 1 on the bow
Four column outer cylinders 17 are installed on the column 3, and the column outer cylinders 17 are formed of a hollow body having an open top and are reinforced by a reinforcing member 130 and connecting members 131 and 132. An inner column 18 of the column is vertically movably inserted into the column outer column 17, and a stop pin 170 at an upper end portion of the outer column 17 is provided in order to surely perform positioning in an ascending and descending state.
Thus, the position of the inner cylinder 18 is fixed. The front and rear end portions of the frame plate 14 extending in the front and rear direction are fixed to the upper end portion of the column inner cylinder 18 at both side portions in the ship width direction. A guide frame 34 formed by bending a pipe material into a mountain shape is fixed to the inner surfaces of both frame plates 14, and a connecting member 29 extending in the front-rear direction is attached to the lower end of the guide frame 34. An attachment plate 38 extending in the front-rear direction is attached to the middle portion of the guide frame 34, and the center plate 33 in the ship width direction is rotatably held by the attachment plate 38.

Further, as shown in FIG. 5, the guide frames 3 on both sides are provided.

The supporting plate 37 is arranged at a position overlapping the guide frame 34 in FIG. I try to prevent it from sagging too much. Further, a pair of left and right hydraulic drive cylinders (elevating means) 55 extending in the vertical direction are installed on the deck 13 in the width direction of the ship, and the upper end of the piston rod thereof is attached to the mounting shaft 51.
It is connected to the frame plate 14 via. This mounting shaft 51
Protrudes inward from the frame plate 14, so that the drive cylinder 55 is arranged within the width of the cutting edge 30 (so as to be located inside both side ends) as shown in FIG. This reduces the width of the device. Further, the drive cylinder 55 is arranged in front of the cutting edge 30 as shown in FIG. 6, and is located upstream in the moving direction of the seaweed net. Therefore, the drive cylinder 55 is used when the cut seaweed falls. It does not adhere to 55.

A cutting edge 30 forming a gate shape in FIG. 4 is attached to the central shaft 33, and three cutting edges 30 are provided in the radial direction as shown by phantom lines in FIG. A driven pulley 32 is attached to one end of the central shaft 33, and a drive motor 39 is attached to the frame plate 14 as shown in FIG.
A drive pulley 35 that is driven and rotated by is attached by the above, and the belt 31 is stretched over the drive pulley 35 and the driven pulley 32 so that the rotational force is transmitted to the central shaft 33. Note that FIG. 4 is drawn by cutting out the central portion in the width direction so that both side portions are close to each other.

The cylinder 20 is attached to one end of each of the connecting members 29 by an attaching shaft 28.
A lower end portion of an operating arm 21 rotatable about an axis 22 is coupled to a tip end portion of a piston rod of the cylinder 20, and an adjusting plate 24 connecting the operating arms 21 to each other is attached to an upper end portion of the operating arm 21. ing. The shaft 22 is fixed to a mounting member 23 mounted on the frame plate 14, and is arranged so as to be substantially coaxial with the central shaft 33. And these comprise the seaweed cutting length adjusting means for adjusting the remaining length of seaweed remaining in the seaweed net after cutting the seaweed attached to the seaweed net.

In the above structure, when the work boat 1 for seaweed cultivation returns to the seaweed farm, the guide extension portion 41 is flipped up on the ship as shown by the phantom line in FIG. 2, and the stern thruster 15 is attached to the bottom of the ship. The boat is propelled by the propeller 11 after being housed (without being projected below the bottom of the boat). The reaper 5 is also lowered from the raised position shown by the solid line in FIGS. 2 to 4 to the position shown by the phantom line. In this lowering operation, the drive cylinder 55 is contracted to lower the frame plate 14 via the mounting shaft 51, and along with this, the support column inner cylinder 18
Also descends inside the column outer cylinder 17, and is also attached to the frame plate 14, the guide frame 34, the central axis 33 of the cutting blade 30, and the adjustment plate 2.
The mechanism such as the operation arm 21 of No. 4 also descends integrally. At the raised position of the seaweed reaper 5, as shown in FIG. 2, the forward field of view 101 of the driver 100 in the bridge 3 is obstructed by the seaweed reaper 5 to be restricted, but when the seaweed reaper 5 is set to the lowered position, the forward view 101 is forwarded. Visibility is not obstructed. The drive cylinder 55 is operated by a control means (not shown) installed in the bridge 3.

When arriving at the seaweed farm, it is necessary to control the course accurately at a low speed. Therefore, the propeller 11 is stopped and the stern thruster 15 is projected below the bottom of the ship as shown in FIG. The bow thruster 16 adjusts the course at low speed and accurately, and the flip-up means 4
By 0, the guide extension portion 41 is rotated forward from the state of the phantom line in FIG. 2 and projected toward the front of the bow as shown by the solid line to cause water to enter. Also, the seaweed reaper 5 is raised. This ascending operation may be carried out in the reverse of the descending operation,
By extending the drive cylinder 55, the mounting shaft 5
The frame plate 14 may be lifted via 1. Further, the drive motor 39 is driven to transmit the rotational force to the central shaft 33 via the drive pulley 35, the belt 31, and the driven pulley 32 to rotate the cutting blade 30, and as shown in FIG. 21 is rotated (swinged) about the axis 22 to set the adjusting plate 24 at a predetermined position described later.

When the boat is moved forward in this state, the guide extension portion 41 scoops up the seaweed net 91 and transfers it by the seaweed net guide 4 in the stern direction. When the seaweed net 91 passes over the seaweed reaper 5, the rotating cutting blade 30 cuts the seaweed attached to the seaweed net 91. FIG. 7 shows the mowing state at this time, and when the adjusting plate 24 is at the forward position shown by the solid line, the seaweed 92 with which the front end of the adjusting plate 24 contacts is cut by the cutting blade 30,
Nori 92 of the part (remaining length) h1 attached to the nori net 91
Will be sent backward together with the seaweed net 91. The cutting blade 30 comes closest to the seaweed net 91 at the highest portion of the rotational movement trajectory 301, while the cutting position of the seaweed 92 is determined by the position of the front end of the adjustment plate 24. When 24 is retracted from the position shown by the solid line in FIG. 7 as shown by the phantom line, the rotational movement locus 301 shows the seaweed net 91.
As a result of being closer to, the remaining length of the seaweed 92 becomes shorter from h2 to h3. Therefore, the adjustment plate 24 may be positioned so that the remaining length becomes a desired length.

The seaweed cut by the cutting blade 30 falls and is supplied into the seaweed storage 50 below the seaweed, but is somewhat washed away by the wind or the like during the fall. However, since the drive cylinder 55 is located upstream of the cutting blade 30 in the moving direction of the seaweed net, the seaweed is prevented from adhering to the drive cylinder 55 during the fall. Further, the entire drive cylinder 55 does not necessarily have to be located in front of the front end edge of the cutting blade 30, and at least a part of the drive cylinder 55 is located in front of the central axis 33 of the cutting blade 30. Then, it is possible to reduce the adhesion of seaweed to the drive cylinder 55.
