Mussel grading device and grading method

Abstract

The invention discloses a mussel grading device and a grading method. The mussel grading device comprises a rack, a feeding unit arranged at the upper part of the front end of the rack, a grading unit and discharging units; the grading unit comprises a first power source and first to Nth stages of rollers, the first to Nth stages of rollers are sequentially arranged in the length direction of the rack, first to Nth stages of grading holes are formed in the first to Nth stages of rollers correspondingly, and the diameters of the first to Nth stages of grading holes are sequentially increased from left to right in the length direction of the rack; mussels respectively enter the corresponding first to Nth stages of rollers through the first to Nth stages of grading holes to be graded, wherein the first power source is used for driving the first to Nth stages of rollers to rotate in the same direction; and the discharging units are arranged in the first to Nth stages of rollers. The mussel seedling separating device is novel in structure and convenient to operate, efficient and high-quality seedling separating operation is achieved, and the problems that in the traditional mussel harvesting process, the labor efficiency is low, the labor intensity is high, the optimal harvesting time is missed, and the product quality is affected are solved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a mussel grading device and a grading method. Background technique [0002] With the implementation of my country's "blue granary" strategy, marine ranching has become the focus of increasing attention. As a popular seafood food, mussels can be eaten in a variety of ways. They are delicious, have high nutritional value, and have high medicinal and therapeutic effects, and are deeply loved by the masses. However, due to the current domestic mussel culture using relatively independent short ropes, the production efficiency is low, and there is a lack of effective connection, which limits the continuity of the collection process and the degree of mechanization is not high. At present, the degree of mechanization of mussel size grading is relatively low, and it basically relies on manual seedling separation. The operation efficiency is low, and it consumes a lot of manpower and ...

Problems solved by technology

However, due to the current domestic mussel culture using relatively independent short ropes, the production efficiency is low, and there is a lack of effective connection, which limits the continuity of the collection process and the degree of mechanization is not high.

At present, the degree of mechanization of mussel size grading is relatively low, and it basically relies on manual seedling separation, which is inefficient and consumes a lot of manpower and time. It often misses the best harvest period, resulting in a decline in the taste of mussels and loss of fishermen's interests.
