Nucleus inserting tool for freshwater mussel breeding pearls

Abstract

The invention provides a nucleus inserting tool for freshwater mussel breeding pearls. The tool comprises a handle, a conducting component, a pearl nucleus pike-off driving component, a guide rod inserting component, a telescopic driving component and a return trigger component, wherein a first mounting groove is formed in the handle, the pearl nucleus poke-off driving component is movably mounted in the first mounting groove through a first spring, and a material poke U-shaped tune is arranged at one end of the pearl nucleus poke-off driving component; a positioning groove is formed in the side wall of the telescopic driving component, the return trigger component is matched with the positioning groove, and an auxiliary driving push block component is arranged on the guide rod inserting component; a needle is arranged at the end of the guide rod inserting component, and the material U-shaped tube is matched with the needle. The conducting component is used for guiding and positioning, the guide rod inserting component conducts positioning on a pearl nucleus to which cell small pieces adhere, and the pearl nucleus poke-off driving component conveys the pearl nucleus to the nucleus inserting position. The nucleus inserting tool is easy to operate, combines conducting, positioning and nucleus inserting, does not need to be replaced by operating tools and can improve the nucleus inserting efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of pearl cultivation, in particular to a core insertion tool for freshwater mussel cultivation pearls. 【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. At present, the most important shellfish used to cultivate light pearls in my country is the triangular sail mussel, but with the increase of the pearl production of the triangular sail mussel, the quality of the pearls is declining, and the benefits of the pearl breeding industry are decreasing. How to further improve the benefits of the triangle sailfish aquaculture industry and ensure the sustainable and healthy development of the freshwater pearl culture indu...

Nucleation is an important part of the pearl culture industry. Improving the efficiency of nucleation and reducing the cost of nucleation is an important way to improve the benefits of the pearl culture industry. At present, for the nucleated pearl nuclei of the triangular sailfish, there is an urgent need for a method that can improve the efficiency of nucleation. Efficiency, and the new tool for core insertion that can reduce production costs will ultimately improve the economic benefits of the pearl culture industry. The nucleus feeder sends the bead nucleus along the channel to the nucleus position. When the channel needle is directly inserted into the epidermis to open the channel, the tissue in the epidermis has been damaged. It will cause the opening of the channel to puncture the epidermis and make the operation fail. Even if the epidermis of the channel is intact, the inserted bead nucleus will aggravate the trauma of the tissue in the epidermis, especially when the inserted bead nucleus does not reach the nucleus. The nuclei are easy to detach and small pieces of cells flow out; and when the inserted bead nucleus enters the deep position of the nucleus, the bead nucleus will severely squeeze the organs of the soft body and cause the death of the operated mother oyster. nuclear tool
