Utility Model Registration No. 3069493

  However, the laver picking machine described in Patent Document 1 has a problem that when the laver is caught on the rotary cutter, the laver culture net is caught in the rotary cutter. When the nori culture net was caught in the rotary cutter, it was necessary to interrupt the nori collection and cut the nori culture net in order to remove it. Due to the cutting of the nori culture net, the repair cost of the nori culture net increases and the problem of poor laver collection efficiency arises. Furthermore, when the rotary cutter breaks down due to the inclusion of a laver culture net, the repair cost of the rotary cutter also increases.

  The present invention has been made paying attention to such a conventional problem, and an object of the present invention is to provide a laver picker that can prevent a laver culture net from being caught in a rotary cutter.

  In order to achieve the above object, a laver plucking machine according to the present invention is provided with a net pulling roller and a rotary cutter that are rotatably provided on an elongated base along the length direction of the net pulling roller. A laver picking machine for collecting laver from the laver culture net by rotating the rotary cutter under the laver culture net pulled by rotation, comprising a guide bar, a holding bar, and a net entrainment prevention member, The guide bar extends in the length direction of the base to support the nori culture net together with the net pulling roller, and horizontally with respect to the base so as to separate the nori culture net by a predetermined distance from the rotary cutter. The holding bar is provided so that it can be fixed by adjusting the position in the vertical direction, and the holding bar extends along the length direction at a position higher than the rotary cutter and is slidable along the circumference of the rotary cutter. Is, the network winding prevention member that is bridged between the retaining bar and the guide bar, characterized.

  The laver picker according to the present invention is used on a ship. When laver is collected from a laver culture net, the laver aquaculture net is arranged so as to cover the laver plucking machine from its end. At this time, the nori culture net is supported by a net pulling roller and a guide bar, and is arranged at a predetermined distance from the rotary cutter. In order to adjust the distance between the laver culture net and the rotary cutter, the guide bar is fixed by adjusting the position in the horizontal direction and the vertical direction with respect to the base. At this time, the holding bar connected to the guide bar is slid along the periphery of the rotary cutter by the meshing prevention member, so that the position of the guide bar can be easily adjusted.

  The net pulling roller and the rotary cutter are rotated by power. Due to the rotation of the net pulling roller, the nori culture net moves relatively from the guide bar toward the net pulling roller. At the same time, the rotary cutter rotates under the nori culture net, and laver is collected one after another from the relatively moving nori culture net. When the guide bar separates the nori culture net by a predetermined distance from the rotary cutter, the nori is not too deep or too shallow, and the nori can be collected efficiently. Moreover, the nori culture net is separated from the rotary cutter by the net entrainment preventing member spanned between the guide bar and the holding bar, and the nori culture net can be prevented from being caught in the rotary cutter. . In addition, it is preferable that the net entrainment prevention member is composed of a plurality of members and is spanned between the guide bar and the holding bar with a gap in the length direction thereof.

  In the laver picker according to the present invention, the net entrainment preventing member is rotatably attached to the guide bar around the guide bar, and the net entrainment preventing member is sandwiched between the base and the base bar. It is preferable to have a fixing belt that can be fixed. In this case, since the net entrainment preventing member rotates about the guide bar with respect to the guide bar, the position can be freely adjusted in the horizontal direction and the vertical direction when adjusting the position of the guide bar. Further, the netting prevention member can be fixed so as not to move by the attachment belt.

  In the laver picker according to the present invention, the net entrainment preventing member is detachably attached to the guide bar and the holding bar, and is attached to the guide bar instead of the net entrainment preventing member and rotates. It is preferable to have a cantilever member for preventing net entrainment extending above the cutter. In the configuration having this cantilever member, when the cantilever member is attached and used instead of the net entrainment prevention member, the nori culture net can be separated from the rotary cutter by the cantilever member, so the nori culture net is the rotary cutter. Can be prevented from being caught. At this time, the cantilever member does not block between the laver hanging from the nori culture net and the rotary cutter compared to the net entrainment prevention member spanned between the guide bar and the holding bar. It is hard to produce.

  The laver picker according to the present invention includes an engine for driving the rotary cutter and a hydraulic pump for driving the net pulling roller, and the hydraulic pump is driven by driving of the engine. It is preferable to be connected to the drive shaft of the engine. In the configuration having the engine and the hydraulic pump, the hydraulic pump can be driven by driving the engine, so that the rotary cutter and the net pulling roller can be driven simultaneously by one engine. For this reason, it is possible to reduce the manufacturing cost and increase the work space on the ship as compared to the case where two engines are used for the rotary cutter engine and the net pulling roller engine. be able to.

  Further, in the laver picker according to the present invention, the laver culture net is formed by stretching a net between two ropes extending in the length direction, and the net pulling roller is fitted with each rope and pulled with rotation. It is preferable to have a plurality of ridges inclined around the side surfaces and inclined so as to guide the ropes from the inside to the guide grooves by rotation around the side surfaces inside the guide grooves. With this configuration having guide grooves and ridges, when the net pulling roller fits the rope of the seaweed aquaculture net in the guide grooves and pulls with rotation, even if the rope is displaced inward from the guide grooves, a plurality of ridges are With the rotation of the pulling roller, the rope can be guided back to the guide groove along the inclination. Since the ridge is composed of a plurality of ridges, it is not necessary to wait until the net pulling roller makes one rotation to return the rope to the guide groove, compared to a case where the ridge is composed of one, and work efficiency can be improved.
