AI Technical Summary
Existing fish fry screening equipment cannot adapt to different types of fish fry, resulting in large screening errors and low pass rates. Traditional manual grading is inefficient.
A fish fry grading and screening device with an adjustable rectangular screening mesh inner diameter was designed. Combined with an arc-shaped anti-jumping plate and a guide frame, it ensures screening accuracy and fish fry safety.
The screening equipment has been adapted to different fish fry sizes, improving screening accuracy and safety, preventing fish fry from escaping, and increasing screening efficiency.
