Abstract

<P>PROBLEM TO BE SOLVED: To provide a laborsaving device for introducing a laver culture boat under a floating laver net in the case of a laver harvesting work, or the like. <P>SOLUTION: A slender guiding member 6 is extended perpendicularly from a supporting shaft 7 rotatably supported between the right and left boat sides. The guiding member 6 is composed of a main shaft 6a and two reinforcing materials 6b reinforcing the shaft from both sides. The main shaft 6a has a doglegged form, the main shaft part ahead of a bent part has a length sufficient to be extended slantly downward from the bow by tilting the guiding member forward and dip the tip end of the main shaft in the sea. An actuator 9 for rotating the supporting shaft 7 is provided for raising or falling the guiding member 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an apparatus for entering a laver culture work boat under a laver net floating in the sea.

  The nori net is fixed to the sea surface by connecting support ropes extending from the corals at both ends (see FIG. 3). The nori picking operation involves passing a work boat under the nori net floating on the sea surface and moving the work boat along the nori net while picking the nori attached to the net using a picker. In order to pass the work boat under the laver net, a person has stood at the tip of the work boat, scooped up the rope with the saddle he had, and passed the boat under the rope. Such scooping work not only requires a great deal of labor, but also requires an extra crew member for this scooping work.

  It is an object of the present invention to automate the laver net scooping operation to save the crew.

  The scooping machine of the present invention is rotatably supported on the boat, and has a long and narrow guide member that extends obliquely downward from the tip of the boat and the tip is submerged in water when it is tilted forward. The net or cable near the sea surface is guided by the guide member and guided onto the boat (claim 1). In use, the boat is slowly advanced toward the net or rope to be scooped up with the guide member tilted forward. In this way, since the guide member extends underwater from the tip of the hook diagonally, the net or cable is caught by this guide member, and then the caught net or cable is guided by the oblique guide member and goes up on the boat. .

  The guide member cannot be turned by human power, but if an actuator is provided to drive the guide member, labor can be surely saved (claim 4).

  The guide member may be straight, but if it is straight, the base of the guide member must be supported at a high position by providing a pedestal or the like in order to sink the tip below the sea surface. Therefore, it is desirable to use a guide member bent into a substantially "<" shape (claim 2). In this way, since the "<"-shaped guide member can straddle the heel, it is not necessary to attach the root of the guide member to a high position.

  Since the seaweed picking machine is installed in the center of the boat, it is impossible to guide the net onto it using only the guide members. Therefore, a guide rail can be provided for guiding the net or the rope guided on the boat by the guide member further to the center of the boat (claim 3). The guide rail may be fixed as long as it does not get in the way.

  As described above, by providing the device of the present invention, the laver picking boat can easily enter under the laver net, and can greatly contribute to labor saving of the boat.

  The laver culture work boat 1 shown in FIGS. 1 and 2 has a length of about 10 m, and a drum type winch 2 for attracting the laver net and a laver picker for plucking the laver attached to the laver net in the center thereof. 3 are installed side by side. A scooping machine 5 is installed at the bow of this boat.

  The scooping machine 5 has an elongated guide member 6, which extends in a perpendicular direction from a support shaft 7 that is rotatably supported between the left and right boat edges. The guide member includes a main shaft 6a and two reinforcing members 6b that reinforce the main shaft 6a from both sides. In both the main shaft and the two reinforcing members, the base is fixed to the support shaft 7, the reinforcing member extends obliquely, and the tip is fixed to the approximate center of the main shaft 6a. The main shaft 6a is bent in a "<" shape, and an FRP pole is used on the tip side from the bent portion for weight reduction. When the main shaft is tilted forward, a portion ahead of the bent portion extends obliquely downward from the tip of the spindle, and has a length such that its tip is submerged in the sea.

  In order to raise and lower the guide member 6, an actuator 9 that rotates the support shaft 7 is provided. Various actuators are conceivable, but here, a linear actuator whose length expands and contracts, and an electric motor driven actuator is used. If hydraulic pressure can be used, of course, a hydraulic cylinder may be used. One end of the linear actuator 9 is attached to the boat body, and the other end is joined to the tip of a short lever 10 fixed to the support shaft 7 by a pin 11. Therefore, when the linear actuator is extended, the guide member 6 rises as shown by a chain line in FIG. 1, and when it is contracted, the guide member falls forward as shown by a solid line in FIG.

  The guide member 6 is normally raised, and when the boat approaches the laver net, the guide member 6 is moved forward by operating the actuator. The actuator 9 is configured so that it can be remotely operated from the rear of the boat (the ship maneuvering position) so that the ship maneuvering and the actuator can be operated by one person. Reference numeral 12 denotes a guide rail extending slightly upward from the bow to the rear.

  As shown in FIG. 3, the laver plowing boat 1 slowly advances the boat toward the support line 21 extending from the anchor 22 that stretches the laver net 20 with the guide member 6 tilted forward, and the support line Is hooked on the main shaft of the guide member. If the boat is further advanced while the support rope 21 is hooked, the main shaft 6a is inclined. Therefore, as shown by the arrow 23a in FIG. 1, the support rope 21 rises along the main shaft in such a manner that it can be scooped up by the main shaft. . Thus, the support rope that has risen on the boat along the main shaft moves from the main shaft 6a to the guide rail 12 and moves rearward along the guide rail, as indicated by an arrow 23b. Finally, as shown by the arrow 23c, the rope 21 falls from the end of the guide rail 12 onto the drum winch 2 and the laver picker 3 on the boat. When the support cord 21 is manually pulled, the laver net 20 rises on the boat, and this net is set in the drum winch 2 and the laver picker 3 as shown by the chain line in FIGS. To do. Thereafter, the laver net 20 is attracted by the drum winch 2, and the boat slowly moves laterally along the laver net (the boat in this state is indicated by reference numeral 25 in FIG. 3). In this way, while the boat moves laterally along the net, the nori attached to the net is cut and harvested by the picker 3 on the boat.

It is a side view of a seaweed culture work boat. It is also a plan view. It is a top view which shows the movement of the boat in a laver picking work.
