AI Technical Summary

Technical Problem

Traditional multi-row egg grading devices cannot dynamically adjust the grading according to the weight of the eggs, resulting in a mismatch between the grading results and the actual quality requirements, and are unable to meet the grading needs of eggs of various sizes.

Method used

It employs a moving clamping assembly and an oblique grading assembly, using a servo motor and hydraulic system to control the clamping and sorting of poultry eggs. Combined with a pressure sensor to detect the weight of the poultry eggs, and a rotary motor to adjust the grading angle, it achieves multi-row sorting by weight.

Benefits of technology

It enables automated continuous conveying and efficient grading of poultry eggs, reduces labor costs, improves grading accuracy, avoids egg breakage, and adapts to the grading needs of poultry eggs of various sizes.
