Description

Technical Field

[0001] This utility model relates to the field of shellfish screening technology, and in particular to a weighing-type multi-stage shellfish vibrating screening device. Background Technology

[0002] Multi-stage shellfish vibrating screen is a device that uses vibration principle to classify and screen shellfish. It is widely used in the field of aquatic product processing. Its core is to separate shellfish by size and specifications through different apertures of multiple layers of screens combined with reciprocating or rotating vibration generated by a vibrating motor.

[0003] In the shellfish processing industry, sorting shellfish by size is a crucial preliminary step for subsequent grading, sales, and further processing. Currently, this step is still primarily done manually. Workers rely on experience to sift through scattered shellfish, separating individuals of different sizes into different containers. After sorting, each size of shellfish is weighed and the data is recorded individually. This traditional model has significant drawbacks. On the one hand, manual sorting relies on subjective judgment and is easily affected by factors such as worker experience, physical strength, and attention, leading to unstable grading accuracy. Shellfish of the same size may be mixed with individuals of significantly different sizes, affecting the standardization of the product. On the other hand, the process of sorting and then weighing each shellfish is cumbersome. For large-scale shellfish processing enterprises, a large amount of manpower is required to meet production needs. Not only is the labor demand high, but the fragmented process also leads to low overall efficiency. Furthermore, long hours of repetitive labor can easily cause worker fatigue, further reducing sorting speed and accuracy. The uncertainty of manual operation also increases raw material losses in subsequent processing stages.

[0004] Therefore, it is necessary to invent a weighing-type multi-stage shellfish vibrating screening device to solve the above problems. Utility Model Content
