A seedling collector with multiple layers of appressorizers inserted through a wire (semi-steel wire) is suspended in the sea, and the seedlings are attached to the appressorizers to collect seedlings and suppress them (thus suppressing oysters in large numbers). After that, the wire of the seedling collecting device is removed and the appressorium with the seedlings attached is separated from each other. Hanging chains with multiple stages of appressorium are formed by passing wires through the tubes alternately, and the multiple hanging chains are hung safely in the sea using a raft, and the seeds and seedlings attached to the appressorium are grown. Farm oysters.

な損失を受ける欠点があった。A conventional hanging chain used for oyster cultivation uses a plurality of appressoria 1 from which seedlings have been harvested, as shown in Figs.
They are connected with a wire 3 through the rfL joint pipes 2, 2, .
... and joint pipes 2, 2, etc. are prevented from falling off, but the adhesion devices 1, 1, etc. are attached to the adjacent upper and lower joint pipes 2, 2, 2, respectively. , 2... are only supported by the end faces of As the temperature rises, the connection between the appressorium and the joint pipe moves unstable due to the strong force of wind and waves, and the wire at the location corresponding to the connection is subjected to complex repetitive loads, causing it to bend, break, or It is rubbed and worn, becomes thin, and becomes easy to cut, and when the wire is cut, accidents such as the hanging chain being scattered into the sea with the oysters occur, resulting in a large loss in oyster aquaculture.

Fittings ii, it, etc. are provided with a counterbore hole 10 in the center of the upper surface into which a lower end 9 of a connecting pipe 8 (to be described later) fits, and a lower end 13 of the fitting 11 is fitted into the upper end 12. The present invention is constituted by a connecting pipe 8 made of a plastic pipe or the like of an appropriate length (typically 20 Cr/'L) provided with an inclined counterbore 14.

るものである。Next, to explain the present invention in detail, a protrusion 16 for preventing the wire 15 from being pulled out is provided at the lower end of a wire 15 of suitable length (usually about 9 m) made of semi-steel wires of No. 13 and No. 14. The other end is connected to the pipe hole 17 of the pipe 8, the lower end 13 is inserted into the through hole 6 of the applicator 5 in which the seedlings were taken, and the wire insertion hole 4 of the joint 11 is inserted in this order.
If the joint pipes 8 and joint soldiers 11 are inserted in succession alternately until the predetermined number of applicators 5 are reached, and the upper end of the wire 15 is fixed to the raft 18 and suspended in the sea, the upper end of each joint pipe 8 is The lower end 1 of the joint 11 corresponds to the inclined counterbore 14 provided in the section.
3 is inserted, the appressorium 5 is pushed upward by the local part of the upper surface of the iron fitting part 14, and the inner circumferential surface of the through hole 6 of the appressorium 5 comes into pressure contact with the outer peripheral surface 7 of the joint 11, and the appressorizer 5 is pushed up. is fixed to the fitting 11, and the lower end 9 of the connecting pipe 8 corresponding to the counterbore hole 10 on the upper surface of the fitting 11 is fitted, so that each fitting N, 11...

優れた実用的効果を有するものである。The hanging chain using the present invention with the above configuration and operation is as follows:
The fitting and the joint pipe are stably connected by wire,
Even if a hanging chain suspended in the sea moves irregularly due to the strong force of wind and waves, the wire will not bend because it is coated with the connecting fittings and joint pipes and resonates as if it were almost one piece. There is no risk of the wire becoming thin or easy to cut due to being worn out, and it can prevent damage such as scattering of wire into the sea when cutting the wire.
It has excellent practical effects.
