図29は帆立貝の収穫作業の一例を示す説明図である。
生育後の帆立貝120…は、例えば、収穫船130上に水揚げされ、ロープ110から取り外され、収穫される。
海中に投入されているロープ110は、ガイドプーリ132を通ってモータで駆動される水揚げプーリ131(巻き揚げ機)で船上に引き上げられる。
FIG. 29 is an explanatory diagram showing an example of a harvesting operation for scallops.
The grown scallops 120 are landed on the harvesting ship 130, removed from the rope 110, and harvested.
The rope 110 thrown into the sea is pulled up on the ship by a landing pulley 131 (winding machine) driven by a motor through a guide pulley 132.

ロープ110の引き上げに際し、プーリ131,132の間には、二股状、或いはY字形等の扱き部材133が配設されており、係止ピン100で保持された帆立貝120を含むロープ110を、例えば二股状の扱き部材133,133間を通す。
扱き部材133,133の二股状部材間には、図30に示したように、ロープ110の外径よりも大きい隙間からなる狭隘部134が設けられており、この狭隘部134に水揚げプーリ131で引き上げられる係止ピン及び帆立貝を含むロープ110を通す。

図30は扱き部材133,133間をロープ110が通過し、扱かれる状態を示している。
生育後の帆立貝を吊り下げ、保持しているロープ110は、水揚げプーリ131の巻き上げ力で矢印のように引っ張られる。
扱き部材133,133間をロープ110が通過する際、ロープ110両側の扱き部材133,133の内側面に、ロープ110に係止ピン100を介して保持されている帆立貝120,120が当接する。
帆立貝120,120の移動は、扱き部材133,133で阻止され、一方ロープ110は矢視印方向に移動し、係止ピン100は残留し、係止ピン100はロープ110の取付孔111に通っている軸部中間部105を含んで軸部101が引張され、延伸することとなる。
この状態を図30で示した。
FIG. 30 shows a state in which the rope 110 passes between the handling members 133 and 133 and is handled.
The rope 110 that holds and holds the scallop after growth is pulled as shown by the arrow by the lifting force of the landing pulley 131.
When the rope 110 passes between the handling members 133, 133, the scallops 120, 120 held on the rope 110 via the locking pins 100 come into contact with the inner surfaces of the handling members 133, 133 on both sides of the rope 110.
The movement of the scallops 120 and 120 is blocked by the handling members 133 and 133, while the rope 110 moves in the direction of the arrow, the locking pin 100 remains, and the locking pin 100 passes through the attachment hole 111 of the rope 110.

For example, in FIG. 31, the scallops 120 are detached from the portion of the locking portion 103, detached, and harvested.

図32では、一方の帆立貝120が係止ピン100の軸部101の一方の抜止片104Aの外側部位から破断して自由となったり、他方が係止部103の部位でこの部分の変形で抜脱したりし自由となる。
このように帆立貝120は係止ピン100から外れ、図29に示すように扱き部材133の下方に配置した収穫籠134に収容され、収穫される。
In FIG. 32, one of the scallops 120 breaks away from the outer portion of one retaining piece 104A of the shaft portion 101 of the locking pin 100, or the other is removed by deformation of this portion at the portion of the locking portion 103. It can be taken off and free.
In this way, the scallop 120 is detached from the locking pin 100, and is housed and harvested in the harvest basket 134 disposed below the handling member 133 as shown in FIG.

以上のように水揚げに際し、扱き部材133,133間をロープ110が通る際、図31、図32で説明したように帆立貝120,120は扱き落とされるが、一方係止ピン100は、抜止片104,104がロープ110の貫通孔111(取付孔)周辺部に引っ掛かり、ロープ110から抜脱するのが阻害される。   As described above, when the rope 110 passes between the handling members 133 and 133 when landing, as shown in FIGS. 31 and 32, the scallops 120 and 120 are handled, but the locking pin 100 is provided with the retaining piece 104. 104 are caught in the periphery of the through-hole 111 (attachment hole) of the rope 110 and are prevented from being removed from the rope 110.

この結果、帆立貝120が離脱した後の係止ピン100の一部は、ロープ110に残留することとなる。
図33は、帆立貝が扱き落とされ、帆立貝水揚げ後の裸のロープを示した図で、要部を拡大した図であり、図34は、全体図である。
As a result, a part of the locking pin 100 after the scallop 120 is detached remains on the rope 110.
FIG. 33 is a view showing a bare rope after the scallops are handled and after landing the scallops. FIG. 33 is an enlarged view of the main part, and FIG. 34 is an overall view.

係止ピン100の破断は様々であり、一義的な破断はなされないが、抜止片104,104によって、係止ピン100はロープ110の取付孔111からの抜け出しが阻害され、図33、図34に示したようにロープ110に残留する。
一本のロープに残留する係止ピンの数は、例えば100本以上と極めて多数であり、ロープ110を再使用する際に、残留係止ピンは邪魔となり、これを一々除去する必要がある。
この係止ピンの除去作業は手作業に頼らざるを得ず、多大の労力と時間とを要する。
図35は、ロープから取り外した係止ピンを示しており、このように種々の形態で係止ピンは帆立貝離脱後のロープに残留することとなる。
The locking pin 100 is variously broken and is not uniquely ruptured, but the retaining pieces 104 and 104 prevent the locking pin 100 from coming out of the attachment hole 111 of the rope 110, and FIGS. 33 and 34. It remains on the rope 110 as shown in FIG.

FIG. 1 is a view for explaining a locking pin for scallop cultivation according to a first embodiment of the present invention.
Is a front view showing the entire locking pin, (b) is an enlarged view of a portion b in FIG. 1 (a), the main portion is a cross-sectional view.

係止ピン1は、丸棒状の軸部2の両端部を尖鋭な挿入部3,3とし、両端部の挿入部3,3の軸方向内方部位に、軸方向内方で対称的に上傾した係止片を突設し、係止部4,4を構成する。
軸部2の軸方向中間部5には、長さ方向に離間して一対の抜止片6,6を径方向外方に突設して備え、抜止片6,6は「ハ」字形に配置される。
抜止片6,6の間隔は、後述するロープの外径と一致するか、或いはこれより若干大きいものとする。
The locking pin 1 has both ends of a round bar-shaped shaft portion 2 formed as sharp insertion portions 3 and 3, and symmetrically upward inward in the axial direction at axially inward portions of the insertion portions 3 and 3 at both ends. The inclined locking pieces are projected to form the locking portions 4 and 4.
The axial intermediate portion 5 of the shaft portion 2 is provided with a pair of retaining pieces 6 and 6 protruding in the radial direction and spaced apart in the length direction. The retaining pieces 6 and 6 are arranged in a “C” shape. Is done.
The interval between the retaining pieces 6 and 6 is equal to or slightly larger than the outer diameter of the rope described later.

尚、抜止片6,6を実施例では「ハ」字形としたが、二つの抜止片を軸部2の中間部5の上下方向に突出するように設け、即ち一方が上方に突出し、他方が下方に突出し、突出方向は互いに軸方向内方に向くように斜めに向かい合うように設けることで抜け止め作用を保持させる構造でも良い。   In the embodiment, the retaining pieces 6 and 6 have a “C” shape, but two retaining pieces are provided so as to project in the vertical direction of the intermediate portion 5 of the shaft portion 2, that is, one projects upward and the other projects. A structure may be provided that keeps the retaining action by projecting downward and providing the projecting directions diagonally facing each other inward in the axial direction.

以上の係止ピン1の軸部2の中間部5の中央部には、脆弱部7を設ける。
脆弱部7は、後述の帆立貝を係止ピン1の両端の係止部4,4に係止、保持した状態で、且つ、育成中の帆立貝の重さ、従って生育後、収穫時における帆立貝の重さよりも大きい力が、係止ピン1に掛かった際に破断する脆弱部7とする。
A fragile portion 7 is provided at the central portion of the intermediate portion 5 of the shaft portion 2 of the locking pin 1 described above.
The fragile portion 7 is a state in which scallops described later are locked and held by the locking portions 4 and 4 at both ends of the locking pin 1 and the weight of the scallops being nurtured, and thus after growth, The fragile portion 7 is broken when a force larger than the weight is applied to the locking pin 1.

脆弱部7は、実施例では丸棒状の軸部2の中間部5の外周から切り込みを円周上に設け、V字形の溝状の切り込みからなる脆弱部とした。
係止ピン1は各部全一体に樹脂で成形し、例えば、前記したように66ナイロンを用いる。
In the embodiment, the fragile portion 7 is a fragile portion made of a V- shaped groove-like cut by providing a cut on the circumference from the outer periphery of the intermediate portion 5 of the round rod-shaped shaft portion 2.
The locking pin 1 is formed of resin in all parts, and for example, 66 nylon is used as described above.

66ナイロンを係止ピンの素材として用いた場合、帆立貝を係止して海中に侵浸した際に海中で水分を吸収し、これにより少し柔らかくなり、また、伸ばすと約3倍程度延伸するために係止ピンの素材として好ましい。
係止ピン1は、例えば軸部2の全長が64mm〜67mmであり、挿入部3,3から係止部4,4の基部までの長さが、例えば7mm〜10mmであり、又係止ピン1の軸部2は、最も径が大きい部分での直径が1.4〜1.8mmである。
When 66 nylon is used as the material for the locking pin, when the scallop is locked and infiltrated into the sea, it absorbs moisture in the sea, making it slightly softer, and when stretched, it stretches about 3 times. It is preferable as a material for the locking pin.
The locking pin 1 has, for example, a total length of the shaft portion 2 of 64 mm to 67 mm, a length from the insertion portions 3, 3 to the base of the locking portions 4, 4 of, for example, 7 mm to 10 mm, The shaft portion 2 of 1 has a diameter of 1.4 to 1.8 mm at the largest diameter portion.

図2は係止ピンに帆立貝を係止し、ロープに吊り下げて実施する帆立貝の垂下式養殖の部分拡大図、図3は同全体を示す図、図4は垂下式養殖の説明図である。
ロープ20は、例えば10〜15mの長さであり、ロープ20に径方向に貫通する取付孔21…を例えば10〜13cmピッチで穿設し、係止ピン1を取付孔21…に挿通する。
FIG. 2 is a partially enlarged view of a scallop drooping culture carried out by locking a scallop on a locking pin and hanging on a rope, FIG. 3 is a diagram showing the whole, and FIG. 4 is an explanatory diagram of the drooping culture. .
The rope 20 has a length of, for example, 10 to 15 m, and the attachment holes 21 penetrating in the radial direction in the rope 20 are formed at a pitch of, for example, 10 to 13 cm, and the locking pins 1 are inserted into the attachment holes 21.

以上において、係止ピン1は、ロープ20が軸部2の中間部5の「ハ」字形に突設した抜止片6,6間に位置し、ロープ20の取付孔21…周辺部に抜止片6,6が位置し、抜止片6,6により取付孔21から係止ピン1…が抜け出すのが阻止される。
このように係止ピン1…は、両端部に帆立貝10,10を係止、保持してロープ20の長さ方向に直交する方向に多数貫通・保持される。
In the above description, the locking pin 1 is positioned between the retaining pieces 6 and 6 in which the rope 20 protrudes in a “C” shape of the intermediate portion 5 of the shaft portion 2. 6 and 6 are located, and the retaining pieces 6 and 6 prevent the locking pins 1 from coming out of the mounting hole 21.
In this way, a large number of the locking pins 1 are passed through and held in the direction orthogonal to the length direction of the rope 20 by locking and holding the scallops 10 and 10 at both ends.

係止ピン1の両端部には、帆立貝10,10、初期の状態では稚貝を耳片11,11に穿設した係止孔を介して吊り下げ保持する。
耳片11,11の係止孔は、係止ピン1の尖鋭な挿入部3,3を通過してその軸方向内方部位に設けた係止部4,4(係止片)の軸方向内方部分に臨み、係止ピン1の両端部位に抜脱不能に係止、保持される。
この状態を拡大して図2で示した。又全体を図3で示した。
ところで、係止ピン1の軸部2の中間部5に設けた脆弱部7は、ロープ20の取付孔21の長さ方向の中間部に位置することとなる。
The scallops 10 and 10 are suspended from both ends of the locking pin 1 through the locking holes formed in the ear pieces 11 and 11 in the initial state.
The locking holes of the ear pieces 11, 11 pass through the sharp insertion portions 3, 3 of the locking pin 1, and the axial directions of the locking portions 4, 4 (locking pieces) provided at the axially inner portions thereof It faces the inner part and is locked and held at both end portions of the locking pin 1 so as not to be removable.
This state is enlarged and shown in FIG. The whole is shown in FIG.
By the way, the weak part 7 provided in the intermediate part 5 of the shaft part 2 of the locking pin 1 is located in the intermediate part in the length direction of the attachment hole 21 of the rope 20.

耳吊り式の帆立貝養殖法及び養殖装置全体の一例を図4の説明図で示した。
海底30に固定したアンカー31,31に、基端部を固定したアンカーロープ32,32の先端部(上端部)間に横ロープ33を結束し、横ロープ33には、長さ方向(横方向)に間隔を開けて複数箇所を浮体34…に結束する。これにより、横ロープ33を海面35下の所定深さに保持する。
An example of the ear-hanging scallop culture method and the entire culture device is shown in the explanatory view of FIG.
A horizontal rope 33 is bound between the anchors 31 and 31 fixed to the seabed 30 between the distal end portions (upper end portions) of the anchor ropes 32 and 32 having fixed base ends, and the horizontal rope 33 has a length direction (lateral direction). ) And a plurality of locations are bound to the floating body 34. Thereby, the horizontal rope 33 is held at a predetermined depth below the sea surface 35.

横ロープ33には、長さ方向に所定間隔で複数のロープ20…を吊り下げる。
各ロープ20…の夫々には、各ロープ20…の長さ方向(縦方向)に所定ピッチで係止ピン1…が前記したように貫通、係止されており、各係止ピン1…の両端部に帆立貝10,10の耳片11,11を係止し、帆立貝10…が吊り下げ保持される。
尚、横ロープ33…の両端部とアンカーロープ32,32の連結部等には、海面上に上半部が露出する露出浮体36…を連結し、海面における養殖場所の目印とする。
以上により帆立貝の垂下式養殖(耳吊式養殖)を実施する。
A plurality of ropes 20 are suspended from the horizontal rope 33 at predetermined intervals in the length direction.
In each of the ropes 20, the locking pins 1 are penetrated and locked at a predetermined pitch in the length direction (vertical direction) of the ropes 20 as described above. The ear pieces 11, 11 of the scallops 10, 10 are locked to both ends, and the scallops 10 are suspended and held.
The exposed floating bodies 36 with the upper half exposed on the sea surface are connected to both ends of the horizontal ropes 33 and the connecting portions of the anchor ropes 32, 32, etc., and serve as marks for aquaculture places on the sea surface.
The scallop drooping culture (ear-hanging culture) is implemented as described above.

図5は養殖した帆立貝の生育が進み、収穫が近い状態を示す図であり、図6は図5の要部拡大図である。
図に示すように帆立貝は成長し、係止ピン1が延びてロープ20の両側に垂れ下がっている。
帆立貝10,10を係止保持した係止ピン1…は、夫々の抜止片6,6がロープからの抜け出しを阻止している。
FIG. 5 is a diagram showing a state in which the scallops cultivated are growing and are close to harvesting, and FIG. 6 is an enlarged view of a main part of FIG.
As shown in the figure, the scallop has grown, and the locking pin 1 extends and hangs down on both sides of the rope 20.
The locking pins 1, which lock and hold the scallops 10, 10, have their respective retaining pieces 6, 6 preventing them from coming out of the rope.

ところで、帆立貝の生育が進み、収穫が近い状態では、既述のように帆立貝からの外側やロープ周にイガイ(ヒルガイ)、フジツボ、ホヤ等の付着物(雑物)が付着する。
図では理解の便のため、帆立貝やロープに付着する雑物を外した状態で示しているが、
実際には、帆立貝10の殻は雑物で膨れあがっており、また、ロープ20は雑物が付着して大径となっている。
By the way, in the state where the growth of scallops progresses and the harvest is near, deposits (miscellaneous matter) such as mussels (barrels), barnacles, and sea squirts adhere to the outside from the scallops and around the rope as described above.
In the figure, for the sake of understanding, the scallops and the rope attached to the rope are shown in a state where they are removed.
Actually, the shell of the scallop 10 is swollen with foreign matters, and the rope 20 has a large diameter due to the adhering foreign matters.

係止ピン1の軸部2の中間部5に設けた脆弱部7は、生育後、収穫時における帆立貝の重さよりも大きい力が係止ピンに掛かった際に破断する脆弱部である。
従って収穫前においては、図9に示したように、ロープ20の取付孔21内において切断されることなく保持されており、ロープ20への係止ピン1を含んで抜止片6,6の抜け止め作用もあって、帆立貝10は、ロープ20に保持されている(図8参照)。
The fragile portion 7 provided in the intermediate portion 5 of the shaft portion 2 of the locking pin 1 is a fragile portion that is broken when a force greater than the weight of the scallop at the time of harvest is applied to the locking pin after growing.
Therefore, before harvesting, as shown in FIG. 9, the rope 20 is held in the attachment hole 21 of the rope 20 without being cut, and the retaining pieces 6 and 6 including the locking pin 1 to the rope 20 are removed. Due to the stopping action, the scallop 10 is held by the rope 20 (see FIG. 8).

次に帆立貝の収穫について説明する。
図7は前記と同様に帆立貝の収穫作業の一例を示す説明図である。
生育後の帆立貝は、例えば、収穫船40で水揚げされ、収穫される。
海中に投入されているロープ20は、ガイドプーリ42を通ってモータで駆動される水揚げプーリ41(巻き揚げ機)により船上に引き上げられる。
Next, harvesting scallops will be explained.
FIG. 7 is an explanatory view showing an example of a scallop harvesting operation in the same manner as described above.
The grown scallops are landed and harvested, for example, on the harvesting boat 40.
The rope 20 thrown into the sea is pulled up on the ship by a landing pulley 41 (winding machine) driven by a motor through a guide pulley 42.

ロープ20の引き上げに際し、ロープに長さ方向に離間して配置されたプーリ41,42の間には、前記したように二股状、或いはY字形等の扱き部材43,43が配設されている。ロープ20をこの扱き部材43,43間に通し、水揚げプーリ41でロープ20を引張、巻き上げる。
扱き部材43,43の二股状部材間には、ロープ20の外径よりも大きい隙間からなる狭隘部44が設けられており、この狭隘部44に水揚げプーリ41で引き上げられるロープ20が通る。
When pulling up the rope 20, the bifurcated or Y-shaped handling members 43, 43 are disposed between the pulleys 41, 42 that are spaced apart from each other in the length direction of the rope 20 as described above. .

次に本実施例に係る係止ピン1のロープ20への取付孔21への挿入、挿通作業を説明する。
ロープ20に係止ピン1を通す取付孔21を穿設する。
取付孔21は、ロープ20に長さ方向に直交するように、例えばドリル12で穿設するものである。
Next, the insertion and insertion work of the locking pin 1 according to this embodiment into the attachment hole 21 into the rope 20 will be described.
An attachment hole 21 through which the locking pin 1 is passed is formed in the rope 20.
The attachment hole 21 is formed by, for example, a drill 12 so as to be orthogonal to the rope 20 in the length direction.

ところで取付孔21は、係止ピン1が軽圧入程度で挿入し得る径とする。
ロープ20への穿孔は、自動機で実施される。
図18の(a)はドリル12による穿孔直前の状態を示し、(b)は穿孔後、ドリル1
2が後退している状態を示している。
By the way, the mounting hole 21 has a diameter that allows the locking pin 1 to be inserted with a light press fit.
The rope 20 is drilled by an automatic machine.
18A shows a state immediately before drilling with the drill 12, and FIG. 18B shows the drill 1 after drilling.
2 shows a state of retreating.

取付孔21の穿孔後、係止ピン1を取付孔21に挿通する。
係止ピン1の取付孔21への挿通は、自動機(ピン打機)により実施される。
係止ピン1を図18(c)のように一端部3A側から矢印で示すように移動し、ロープ20の取付孔21に挿入させる。
After the mounting hole 21 is drilled, the locking pin 1 is inserted into the mounting hole 21.
The insertion of the locking pin 1 into the mounting hole 21 is performed by an automatic machine (pinning machine).
As shown in FIG. 18C, the locking pin 1 is moved from the one end 3 </ b> A side as indicated by the arrow, and is inserted into the attachment hole 21 of the rope 20.

ところで係止ピン1は、取付孔21への挿通に際し、先部に係止部4Aを有すること、
進行方向に臨む抜止片6Aを有し、これら4A,6Aは、挿通孔11の径よりも大きく外方に突出していることから挿入時に抵抗となるが、係止部4A、抜止片6Aは係止ピンの挿入方向に対し順方向に傾斜しているので順方向に撓み、進入が容易になされることとなる。
By the way, when the locking pin 1 is inserted into the mounting hole 21, it has a locking portion 4A at its tip.
There are retaining pieces 6A facing in the traveling direction, and these 4A and 6A protrude outwards larger than the diameter of the insertion hole 11, so that they become resistance when inserted, but the locking portions 4A and the retaining pieces 6A are engaged. Since it inclines in the forward direction with respect to the direction in which the stop pin is inserted, it bends in the forward direction and can be easily entered.

ところで、係止ピン1には、抜止片6,6の間で、軸部2の中間部5には前述したように2カ所の脆弱部7、7が形成されている。
係止ピン1のロープ20の取付孔21への挿入に際し、軸周に突出した係止部4A、抜止片6Aの取付孔21への進入に際し、係止部4A、抜止片6Aが撓み易い方向ではあるが、係止部4A、抜止片6Aの取付孔21への進入時に抵抗となり、係止ピン1には軸方向への力が作用することとなる。
この力は、脆弱部7,7にも作用し、脆弱部7,7を曲げようとし、座屈する力が作用することとなる。
By the way, the locking pin 1 is formed with the two weak portions 7 and 7 between the retaining pieces 6 and 6 and the intermediate portion 5 of the shaft portion 2 as described above.
When the locking pin 1 is inserted into the attachment hole 21 of the rope 20, the locking part 4 </ b> A and the retaining piece 6 </ b> A are easily bent when entering the attachment hole 21 of the retaining part 4 </ b> A and the retaining piece 6 </ b> A protruding from the shaft periphery. However, when the locking portion 4 </ b> A and the retaining piece 6 </ b> A enter the mounting hole 21, resistance is generated, and a force in the axial direction acts on the locking pin 1.
This force also acts on the fragile portions 7 and 7, so that the fragile portions 7 and 7 are bent and a buckling force acts.

軸部2の一般部51よりも断面積が小さい部位で形成された脆弱部7,7は、軸部2の一般部51,51と一体の中心部71と、この中心部71に一体に形成された放射状に延びる一体の複数の放射壁部、実施例では、十字形をなすように4枚の放射壁部74…とで構成されている。
複数枚、実施例では4枚の翼状の放射壁部74…が軸方向に延びており、放射壁部74…により脆弱部7,7が構成されているので、脆弱部7の軸方向への剛性が向上し、係止ピン1の軸方向への力に対して曲がり難く、極めて座屈し難くなる。
The weakened portions 7 and 7 formed in a portion having a smaller cross-sectional area than the general portion 51 of the shaft portion 2 are formed integrally with the central portion 71 and the central portion 71 integrated with the general portions 51 and 51 of the shaft portion 2. A plurality of radially extending integral radiating wall portions, in the embodiment, four radiating wall portions 74 are formed so as to form a cross shape.
A plurality of, in the embodiment, four wing-shaped radiating wall portions 74 extend in the axial direction, and the fragile portions 7 are formed by the radiating wall portions 74, so that the fragile portion 7 extends in the axial direction. Rigidity is improved, it is difficult to bend against the force in the axial direction of the locking pin 1, and it is extremely difficult to buckle.

従って、係止ピン1をロープ20の取付孔21へ挿入するに際し、ピン打機による自動ピン挿入作業時に、脆弱部7,7の部分で曲がったりすることなく、直線状態を保持して円滑に係止ピン1をロープ20の取付孔21に挿入することができる。
従って、係止ピンを自動機を用いて、係止ピン1が曲がることなく、直線状態を維持して円滑、確実に、迅速に効率良くロープ20の取付孔21に打ち込む(挿通)ことができる。
Accordingly, when the locking pin 1 is inserted into the attachment hole 21 of the rope 20, the straight state is maintained smoothly without being bent at the weakened portions 7 and 7 during the automatic pin insertion operation by the pin hitting machine. The locking pin 1 can be inserted into the attachment hole 21 of the rope 20.
Therefore, the locking pin 1 can be driven (inserted) into the attachment hole 21 of the rope 20 smoothly, reliably, quickly and efficiently without bending the locking pin 1 by using an automatic machine. .

図18の(d)は係止ピン1をロープ20の取付孔21に挿通し、保持させた状態を示している。
係止ピン1の一対の抜止片6,6間の中間部5がロープ20の取付孔21に臨み、抜止片6,6は取付孔21の両開口部の外側に臨んでロープ20の外周に位置し、取付孔21から係止ピン1がの抜け出すのを防止する。
FIG. 18D shows a state in which the locking pin 1 is inserted and held in the attachment hole 21 of the rope 20.
The intermediate part 5 between the pair of retaining pieces 6, 6 of the locking pin 1 faces the attachment hole 21 of the rope 20, and the retaining pieces 6, 6 face the outside of both openings of the attachment hole 21 and on the outer periphery of the rope 20. It is located and prevents the locking pin 1 from coming out of the mounting hole 21.

係止ピン1の2カ所の脆弱部7,7は、前記した通り抜止片6,6の基部近傍で、抜止片6,6間に設けられているので、ロープ20の取付孔21の開口部に極めて近い外側に位置している。
図18(d)は係止ピン1をロープ20に取付孔21を介して挿通、保持させた状態を示しているが、併せて帆立貝の耳片に穿孔し、帆立貝の穿孔部(耳吊り孔)に係止ピン1の挿入部3を通し、係止部4を穿孔部を通して係止部の返し構造で係止ピン端部に係止、保持する。
Since the two weak portions 7 of the locking pin 1 are provided between the retaining pieces 6 and 6 in the vicinity of the base of the retaining pieces 6 and 6 as described above, the openings of the attachment holes 21 of the rope 20 Is located very close to the outside.

In such a state where a large number of scallops 10 are locked and held on the rope 20 via the locking pins 1, the rope 20 is suspended in the sea, and the scallops are cultivated in the ear.

ところで、本実施例では、放射壁部74…の外面75を軸部2(その中間部5)の一般部51の外周52と一致させた。
仮に、放射壁部74…の外面7一般部の外周51よりも突出させたとしよう。
これによれば、脆弱部7は座屈し難くなる。しかしながら、係止ピン1をロープ20の取付孔21に挿通(ピン打ち)するときに脆弱部7がより座屈し難くはなる。
しかしながら、係止ピン1をロープ20の取付孔21に挿通する際、取付孔21に引っ掛かりが生じ、挿通作業に支障を来すこととなる。

However, when the locking pin 1 is inserted into the attachment hole 21 of the rope 20, the attachment hole 21 is caught and the insertion operation is hindered.

一方、放射壁部74…の外面75を一般部51の外周52よりも窪ませると、取付孔21への挿通作業は容易化するが、係止ピン1は座屈し易くなる。
この点、実施例のように放射壁部74…の外面75を軸部2の一般部51の外周と一致させたので放射壁部74…は軸部外周に突出せず、脆弱部7,7はロープ取付孔への挿通に際して抵抗となることが無く、取付孔21の挿通が円滑に、容易になされることとなる。一方、係止ピン1のロープ20の取付孔21への挿通時に座屈し難くなる。
従って、係止ピンの挿通作業(ピン打ち作業)が曲がることなく、円滑に、容易に、確実になされる。
On the other hand, when the outer surface 75 of the radiating wall portion 74 is recessed from the outer periphery 52 of the general portion 51, the insertion operation into the mounting hole 21 is facilitated, but the locking pin 1 is easily buckled.
In this respect, since the outer surface 75 of the radiating wall portion 74 is made to coincide with the outer periphery of the general portion 51 of the shaft portion 2 as in the embodiment, the radiating wall portion 74 does not protrude to the outer periphery of the shaft portion, and the weakened portions 7 In this case, there is no resistance when the cable is inserted into the rope attachment hole, and the attachment hole 21 can be inserted smoothly and easily. On the other hand, it becomes difficult to buckle when the locking pin 1 is inserted into the attachment hole 21 of the rope 20.
Therefore, the insertion operation (pinning operation) of the locking pin is smoothly, easily and reliably performed without bending.

帆立貝は成長し、係止ピン1が延びてロープ20の両側に垂れ下がる。これを前記と同様に図20で示した。
帆立貝10,10を係止保持した係止ピン1…は、前記したように取付孔21の開口部両側に設けられた脆弱部7,7の部分が、放射壁部74…で曲がり難くなっており、座屈し難くくはあるが、他の部位に比較して断面積が小さいので、脆弱部7,7の部分から曲がり、垂れ下がるが、脆弱部7,7の軸方向外側部位に抜止片6,6が設けられており、ロープ20からの抜け出しは阻止される。
The scallop grows and the locking pin 1 extends and hangs down on both sides of the rope 20. This is shown in FIG. 20 in the same manner as described above.
As described above, the locking pins 1 that hold the scallops 10 and 10 are difficult to bend at the radiating wall portions 74 at the fragile portions 7 and 7 provided on both sides of the opening of the mounting hole 21. Although it is difficult to buckle, the cross-sectional area is small compared to other parts, so it bends and hangs down from the fragile parts 7, 7. , 6 are provided to prevent the rope 20 from coming out.

図21は、第2実施例に係る係止ピンを用いる収穫時における扱き部材間をロープが通過し、扱かれる状態を示す説明図であり、前記した通り二股状の扱き部材43,43間に通し、前記した水揚げプーリでロープ20は引張されて巻き上げられる。
前記したように扱き部材43,43間をロープ20が矢印のように引っ張られて通過し、扱かれ、扱き部材43,43間をロープ20が通過する際、ロープ20両側の扱き部材43,43の内側面にロープ20に係止ピン1を介して保持された帆立貝10,10が当たる。
FIG. 21 is an explanatory view showing a state in which the rope passes between the handling members at the time of harvesting using the locking pins according to the second embodiment and is handled, and as described above, between the bifurcated handling members 43, 43. The rope 20 is pulled and wound up by the above-described landing pulley.
As described above, when the rope 20 is pulled and passed between the handling members 43 and 43 as shown by arrows, the handling members 43 and 43 on both sides of the rope 20 are handled when the rope 20 passes between the handling members 43 and 43. The scallops 10, 10 held on the rope 20 via the locking pins 1 hit the inner side surface.

この際、ロープ20の矢印方向への移動で、扱き部材43,43で阻止された帆立貝10,10により、係止ピン1はロープ20の取付孔21に通っている軸部中間部5を含んで引張される。
この結果、前記と同様に係止ピン1は、取付孔21に貫通保持されている軸部2の中間部5の断面積が小さい脆弱部7,7の部分から優先的に破断することとなる。
At this time, the locking pin 1 includes the shaft intermediate portion 5 that passes through the attachment hole 21 of the rope 20 by the scallops 10 and 10 that are blocked by the handling members 43 and 43 due to the movement of the rope 20 in the arrow direction. It is pulled by.
As a result, similarly to the above, the locking pin 1 is preferentially broken from the weakened portions 7 and 7 where the cross-sectional area of the intermediate portion 5 of the shaft portion 2 penetratingly held in the mounting hole 21 is small. .

この結果、係止ピン1は軸部中間部5の軸方向に離間した2カ所の脆弱部7,7から分離する。
係止ピン1は、軸部の中間部5が分離した結果、2つの抜止片6,6がロープ20の取付孔21の外側に位置していることから、抜止片6,6が取付孔21の周辺部に引っ掛かることなく取付孔21から分離して抜け出す。
この結果、二つに破断した係止ピンはロープ20の取付孔21から抜け出し、帆立貝10,10は破断した係止ピンとともにロープ20から離脱することとなる。
As a result, the locking pin 1 is separated from the two weak portions 7 and 7 that are spaced apart in the axial direction of the shaft middle portion 5.
As a result of the separation of the intermediate portion 5 of the shaft portion of the locking pin 1, since the two retaining pieces 6, 6 are positioned outside the attachment hole 21 of the rope 20, the retaining pieces 6, 6 are attached to the attachment hole 21. It is separated from the mounting hole 21 without being caught by the peripheral part of the lens.
As a result, the latch pin that is broken in two comes out of the attachment hole 21 of the rope 20, and the scallops 10 and 10 are detached from the rope 20 together with the broken lock pin.

ところで、係止ピン1の両端部の帆立貝10,10は、実際には外部に雑物が付着してるので、夫々の重量がさ異なること、生育度合いが夫々異なり、外形、外寸が異なることから、左右の扱き部材43,43の一方にこの側の帆立貝が先行して扱かれることが多く、脆弱部7,7は、一方のみが他方に先行して破断する場合が通常である。
この結果、脆弱部の一方が他方に先行して破断し、抜止片6,6間の軸部中間部5は一方の脆弱部から破断し、他方は繋がった状態となり、続いて他方の脆弱部が破断することから、ロープ20の取付孔21から中間部5は抜け出すこととなる。
By the way, the scallops 10 and 10 at both ends of the locking pin 1 are actually attached to the outside, so that their weights are different, the degree of growth is different, and the outer shape and outer dimensions are different. Therefore, the scallops on this side are often handled in advance on one of the left and right handling members 43, 43, and usually only one of the fragile portions 7, 7 breaks ahead of the other.
As a result, one of the fragile portions breaks before the other, the shaft middle portion 5 between the retaining pieces 6 and 6 breaks from one fragile portion, the other is connected, and then the other fragile portion Is broken, the intermediate portion 5 comes out of the attachment hole 21 of the rope 20.
