When the weight of the cuttlefish eggs at the position reaches a certain amount, particularly when the sum of the weight of the cuttlefish eggs at the position and the weight of the counterweight balls is greater than the sum of the weights of the limit stops and the support stops (because the upper guide wheel is rotatably arranged on the support shaft rod through the bearing, the friction force between the upper guide wheel and the support shaft rod is small and negligible), the cuttlefish egg-attaching rope rotates around the upper guide wheel, so that the vertical egg-attaching rope with the cuttlefish eggs moves downwards until the support stops in the uppermost self-adjusting device abut against the counterweight blocks;
then, the parent cuttlefish continues to lay eggs at another position on the vertical egg-attaching rope positioned outside the isolation net cage, and when the sum of the gravity of the cuttlefish eggs at the position is larger than the gravity of one balancing weight, the cuttlefish egg-attaching rope rotates around the upper guide wheel again to enable the vertical egg-attaching rope attached with the cuttlefish eggs to move downwards continuously until a supporting stop block in the self-adjusting device at the middle part abuts against the balancing weight;
then, the parent cuttlefish continues to lay eggs at another position on the vertical egg-attaching rope positioned outside the isolation net cage, and when the sum of the gravity of the cuttlefish eggs at the position is larger than the gravity of one balancing weight, the cuttlefish egg-attaching rope rotates around the upper guide wheel again to enable the vertical egg-attaching rope attached with the cuttlefish eggs to move downwards continuously until a supporting stop block in the self-adjusting device at the bottom abuts against the balancing weight;
and finally, the parent cuttlefish continues to lay eggs at another part on the vertical egg-attaching rope positioned outside the isolation net cage, when the sum of the gravity of the cuttlefish eggs at the part is larger than the gravity of one balancing weight, the cuttlefish egg-attaching rope rotates around the upper guide wheel again, the vertical egg-attaching rope attached with the cuttlefish eggs continuously moves downwards until the balancing weight in the self-adjusting device at the top abuts against the limiting sleeve, and the cuttlefish egg-attaching rope does not rotate.
Thus, when the egg attaching amount of the parent cuttlefish at one part on the vertical egg attaching rope reaches a certain amount, the vertical egg attaching rope attached with the cuttlefish eggs moves downwards for a certain distance; therefore, the problem that a large number of cuttlefish eggs wrapped in the middle are slow in development and even rotten and dead due to the fact that a large number of cuttlefish eggs are stacked on a certain position on the vertical egg-attaching rope, and the hatching rate is reduced seriously is solved, meanwhile, parent cuttlefish do not need to migrate to the egg-laying position, the parent cuttlefish cannot be disturbed to lay eggs, and the egg-laying efficiency of the parent cuttlefish cannot be influenced; after the vertical egg-attaching rope attached with the cuttlefish eggs moves downwards, a part of cuttlefish eggs move to the lower part of the left cavity, and the cuttlefish eggs are protected by the isolation net cage.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
