Description

  The present invention relates to, for example, a method for removing a shell locking tool penetrating through a rope for cultivating scallop shells by ears from the rope after the cultivation, and a shell locking tool extraction device used therefor.

  When scallops are cultivated by ear-hanging, as shown in FIG. 11, a scallop cultivating rope (usually a resin knitted rope: hereinafter referred to as “rope”) C is penetrated by a resin shell anchor D, and the rope The protruding portion E of the shell locking tool D protruding from C is inserted into the hole opened in the ear of the scallop B, and a number of scallops B are suspended from the rope C. It is hung on a horizontal rope A stretched horizontally in the sea. The rope C, which has been lifted from the sea and removed the scallops, is reused for the next cultivation. In this case, the shell locking tool B remaining on the rope C is removed from the rope C, and a new shell locking tool D is inserted into the rope C after the removal.

  In the scallop ear suspension culture, the scallop that has been cultured and grown is removed from the shell lock D. In this case, the shell locking tool D may be detached from the rope C together with the scallop, but may remain on the rope C. The rope is reused for the next scallop culture. In this case, since the shell locking tool D remains on the rope C, it is difficult (cannot be) reused. Therefore, the shell locking tool D is removed (removed) from the rope C before being reused.

  The present patent applicant has previously developed a shell locker removal device that automatically removes (removes) the shell lock D from the rope C. This pulling device pulls the protrusion E of the shell locking tool D protruding from the rope C into the rotary pulling tool and pulls the shell locking tool D into the rope while pulling the rope C where the shell locking tool D remains. It is extracted from C (see Patent Document 1).

(Example of extraction device)
An embodiment of the extraction device of the present invention will be described below with reference to the drawings. The extraction device of this embodiment includes an apparatus main body 10 (FIG. 1) and a lid 12 (FIG. 1) attached to the apparatus main body 10 with a hinge 11 (FIG. 1) so as to be opened and closed.

  A rope passage 1 is formed on the upper surface of the apparatus body 10. The rope passage 1 is formed in a direction crossing the apparatus main body 10 (left-right direction in FIG. 1). A rope traction tool 13 (FIG. 1) that pulls the rope C into the rope passage 1 and travels on the rope passage 1 is provided at the end of the outlet of the apparatus main body 10. A rope guide 14 (FIG. 1) and a guide roller 15 (FIG. 1) are provided to guide the rope C drawn into the rope passage 1 to be easily drawn into the rope passage 1, and protrude through the rope C to the side of the rope passage 1. Rotation-type extraction tools 3a and 3b for pulling out and removing the shell lock D from the side of the rope passage 1 are provided.

  A drive body 16 (for example, a motor: FIGS. 9 and 10) is connected to the apparatus body 10, and a power transmission mechanism 17 (for transmitting the rotational driving force of the drive body 16 to the rope traction tool 13 and the removal tools 3a and 3b to rotate them. 9), a discharge shooter 18 (FIGS. 1 and 8) and the like for discharging the shell locking tool D extracted from the rope C to the outside of the apparatus main body 10 are provided.

  As shown in FIG. 1, the rope passage 1 has a V-shaped cross section on the inlet side 1a and the outlet side 1b, and has an upward U-shaped groove between the inlet side 1a and the outlet side 1b. The opening is slightly wider than the thickness of the rope C so that the lower part of the rope C can enter. The shape of the rope passage 1 may be other shapes.

  The rope traction tool 13 (FIGS. 1 and 8) is for pulling (pulling) the rope C into the rope passage 1 of the apparatus main body 10 and includes a traction roller 20 and a pressing roller 21 sandwiching the rope C. The pulling roller 20 is rotationally driven by the rotational force of the driving body 16 provided in the apparatus main body 10. In this case, the rotation of the driving body 16 is decelerated by the reduction gear R (FIGS. 9 and 10) and transmitted to the pulling roller 20 via the power transmission mechanism 17. The pressing roller 21 (FIG. 8) presses the rope C wound around the outer peripheral surface of the pulling roller 20 against the outer peripheral surface of the pulling roller 20 so that the rope C is smoothly pulled without slipping. The pressing roller 21 is rotatably attached to the lower portion of the vertically oriented arm 22 (FIG. 9). The lower end of the arm 22 is L-shaped inward (leftward in FIG. 1), and the L-shaped tip is rotatably attached to the apparatus body 10 by a support shaft 23 (FIGS. 1 and 8). When the upper end portion of the handle 24 (FIGS. 1 and 8) attached to the upper end portion of the arm 22 is pulled in the direction of arrow A in FIG. 8 and tilted to the right, the pressing roller 21 is separated from the outer peripheral surface of the pulling roller 20. It is like that.

  When the rope C is sandwiched between the pulling roller 20 (FIG. 8) and the pressing roller 21 (FIG. 8) as shown in FIGS. 3 (a) and 3 (b), the gap between the rollers 20 and 21 is rotating. When the tip of the rope C is inserted into the rope C, the rope C is automatically drawn between the rollers 20 and 21. In this state, when the driving body 16 (FIG. 9) is rotated and the pulling roller 20 is rotated in the direction of the arrow Y in FIG. 3 via the power transmission mechanism 17 (FIG. 9), it is sandwiched between the rollers 20 and 21. The rope C is pulled in the rotational direction of the pulling roller 20 and travels on the rope path 1. When the running rope C is jammed between the rollers 20 and 21, the handle 24 is tilted in the direction of the arrow Z in FIG. 8, and the upper part of the arm 22 (above the support shaft 23 in FIGS. 8 and 9) is moved. Opening outward (in the direction of arrow Z), the presser roller 21 is tilted in the same direction and separated from the pulling roller 20 to widen the gap between the rollers 20 and 21, and the rope C is pulled out. When the handle 24 is returned to the original position (the direction opposite to the arrow Z) after the drawing, the pressing roller 21 returns to the same direction. At this time, the lower part of the arm 22 is pulled back by a tension spring not shown.
