Description

Technical Field

[0001] The utility model relates to the technical field of egg grading, in particular to an egg grader in the egg selection area. Background Art

[0002] An egg grader is an automatic screening device for grading the quality of eggs. According to the advanced degree of the equipment, it is divided into a full-automatic egg grader and a semi-automatic egg grader. Now, with the development of technology, a full-automatic egg grader with automatic loading and unloading and full-automatic grading has come out and has been adopted by some large and advanced manufacturers. However, for most small and medium-sized enterprises, considering the purchase cost and replacement cost, they still use the relatively economical semi-automatic egg grader.

[0003] Compared with the full-automatic egg grader, the semi-automatic egg grader has, on the one hand, a lower advanced degree in each functional area, and on the other hand, requires manual egg loading. When the semi-automatic egg grader in the egg selection area is working, a large number of fresh eggs with uneven quality are transported to the egg selection area. The fresh eggs are taken by the staff and placed at the front end of the egg loading conveyor of the egg grader by hand. The fresh eggs are transported by the egg loading conveyor. However, because the space of the egg loading conveyor is relatively small and the manual picking speed is fast, the eggs are easily stacked at the front end of the egg loading conveyor and blocked by the multi-channel partition plates of the egg loading conveyor, affecting the smooth egg loading. And most of the existing semi-automatic egg graders do not have auxiliary dredging measures for egg loading. The current practice is to regularly use the hand of the staff to dial the egg body to dredge the egg loading. This method not only has a poor effect, but also increases the workload of the staff and needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an egg grader in the egg selection area, which solves the problems that the egg grader in the egg selection area is easy to be blocked during egg grading and feeding, and lacks auxiliary dredging measures.
