Description

Automatic sorting device for sea cucumber seedlings

technical field

The utility model relates to a sorting device, in particular to an automatic sorting device for sea cucumber seedlings.

Background technique

Sea cucumber farming has formed a large-scale farming industry in my country's coastal areas, and a very important link in the breeding process is the cultivation of sea cucumber seedlings. At present, sea cucumber seedlings are mostly cultivated in industrialized indoor seedlings, and the seedling cycle is generally 3 to 6 months. After the sea cucumber seedlings are cultivated to a certain size, the sea cucumber seedlings can be put into the open-air cultivation pond for cultivation. Multiple seedling pools are distributed in each nursery room, and each seedling pool is an independent water body, and the water body in the seedling pool needs to be replaced at regular intervals (half a month or a month). At this time, it is necessary to collect the sea cucumber seedlings together, and sort the sea cucumber seedlings according to their size (usually divided into three types: large, medium and small), and then put the sea cucumber seedlings of different sizes into different nursery pools for cultivation. This process is usually called dumping. Now the entire process of pouring ponds is done manually by workers, requiring 6 to 8 workers. The labor intensity of the workers is high, the efficiency of seedling separation is low, the damage rate of sea cucumber seedlings is high, and the environment where the workers work is humid and the light is dim. Restricted and influenced the large-scale industrialized seedling raising cost of sea cucumber seedlings and the quality of sea cucumber seedlings. Therefore need to have a kind of device that can carry out automatic sorting to sea cucumber seed in the sea cucumber breeding industry now.
