Description

Automatic weight grading device for fish processing

Technical Field

The invention relates to the field of marine product processing equipment, in particular to an automatic weight grading device for fish processing.

Background

China is a big aquatic product country, and the aquaculture plays an important role in national economy. However, the processing proportion of aquatic products in China is far lower than the average level in the world, according to statistics, 70% of the total amount of the aquatic products in the world is sold after being processed, the fresh sale proportion does not exceed 25%, the processing proportion of the aquatic products in China only accounts for about 30% of the total amount, the output value is very low, the production development of fishery in China is severely restricted, and the classification of the size of fishes as the pre-processing is an important link.

The classification of the caught fishes mainly comprises two types of manual classification and machine classification, wherein the manual classification mainly separates big and small fishes by artificial observation; also through a separation box with fixed grid spacing, fish is poured into the separation box, fish smaller than the grid spacing falls into a special container through the grid, fish which can not pass through is put into other containers, many domestic fishing boats and medium and small-sized processing enterprises mostly adopt manual grading operation, but the labor intensity is large, the grading is rough, for large-scale fishing boats, due to large capture amount and long manual sorting time, the fish is easy to deteriorate and has to be thrown away, not only the economic benefit is reduced, but also the fishery resources are seriously wasted, for the subsequent processing of the fished fish, a grading processing device is necessary, Chinese patent discloses an automatic grading device for fish weight, (No. CN205110140U is issued), the patent technology realizes the automatic grading screening of the fished fish according to the specification size, the angle of the grading device and the spacing between the grading rollers can be conveniently adjusted according to the needs, the classification method is reliable, but a small amount of material needs to be fed for multiple times to achieve a good classification effect, otherwise, the problem of incomplete separation exists, and the separation effect is not good.
