The invention relates to the field of
aquaculture, in particular to a device for screening
scallop seedlings. The device for screening the
scallop seedlings comprises a power device, a
frequency conversion device, an eccentric
crank arm mechanism, a connecting rod, an adjusting support, a
machine body, a
machine body support, a
seedling feeding tank, a screen support, a water spraying
pipe, a barrier, a primary screen, a secondary screen, a primary screen collection box, a collection box
discharge outlet, a secondary screen storage box, a storage box
discharge outlet, a
seedling collection tank and an overflow port. In the invention, a mechanical device is used for substituting the traditional manual
seedling screening operation, so that a large amount of labor force is saved, the labor intensity of employees is greatly reduced, and the work efficiency is greatly improved at the same time; moreover, the whole process of the screening of
scallop seedlings is performed in water in the operation process, so the
survival rate of the seedlings is ensured, and the screened seedlings have good quality and consistent specification; and seedling washing and screening are finished at one time, the operation link of seedling washing is saved, and
pollution can be removed and two grades of scallop seedlings can be sorted through once-through operation.
