A pearl breeding device for pearl shell cultivation

Abstract

The present invention provides a pearl breeding device for pearl shell cultivation, which comprises a transverse cultivation raft body, fixed mounting columns, an adjustable bearing main cable holder,a positioning mechanism, a cultivation cage, and a cage suspension cable, wherein the transverse cultivation raft holder body is longitudinally and evenly arranged, both sides of the transverse cultivation raft body are provided with the fixed mounting columns, a main cable holder mounting frame is arranged on the fixed mounting columns, the adjustable bearing main cable holder is mounted on themain cable holder mounting frame, the upper end of a traction cable is fixed on a fixed beam, the lower end of the traction cable is fixed by a fixed iron anchor, the upper end of the cage suspensioncable is connected with the adjustable bearing main cable holder, the cultivation cage is arranged at the lower end of the cage suspension cable, both sides of the cultivation cage are provided with guide locking mechanisms, and the guide locking mechanisms are respectively matched with the traction cable. The height of the adjustable bearing main cable holder can be adjusted so as to create a good ecological environment for pearl shell cultivation and pearl breeding; the pearl breeding device has excellent anti-wind-wave performance.

Description

【Technical field】 [0001] The invention relates to the technical field of pearl cultivation, in particular to a pearl cultivation device for pearl cultivation. 【Background technique】 [0002] Pearl cultivation refers to the fact that according to the physiological function that pearl oysters can secrete nacre to form pearls, small pieces of cells or small pieces of pearl nuclei and small pieces of cells are implanted in the body of pearl oysters, and pearls are cultivated after a certain period of time. In domestic and foreign pearl cultivation, the methods of raising pearl oysters can be roughly divided into three types: 1. The piling method uses wooden or cement pillars to pierce directly on the seabed. The number of pilings varies. Hanging shell cages for raising shellfish and raising pearls. 2. The caisson culture method puts shellfish in net cages, and tries to fix them after sinking into the seabed, so as to raise shellfish and raise pearls. 3. The method of floating ...

AI Technical Summary

Problems solved by technology

There are also bamboo, wood, iron and other materials used to set up frames, supported by floating buckets and anchored to form floating rafts to hang shellfish and pearls. The above-mentioned cultivation methods: The first method requires waiting for low tide to see piles, which is not convenient for production operations ; The second type is cultivated at the bottom for a long time, and the bait organisms are insufficient, which is not conducive to the growth of shellfish; although the third type is easier to operate than the first two, the breeding raft floats on the water surface with the tide and is easily affected by wind and waves. Severe losses in production and economy, high risk in breeding

And most of these existing culture rafts are a plurality of independently cultured clam cages, one by one respectively by hooks or slings hanging on the same floating rope to cultivate the mode of raising pearls, because each cultured shellfish on the floating rope The cages are all independent rather than tightly connected together and then integrated with the floating rope, so their ability to resist wind and waves is greatly reduced, and it is difficult to meet the requirements of the majority of farmers. Therefore, a pearl cultivation device for pearl cultivation is proposed.
