Subsequently, the fresh pears enter the visual inspection component 4 under the conveyance of the conveyor belt 31, and the fresh pears are imaged in turn. The image-taking mechanism 42 compares and judges the collected information in the controller to obtain the sorting result, and controls the telescopic rod 531 of the driving mechanism 53 to extend and retract. After a specific time, the sorting plate 52 is driven to move to the specified position under the receiving plate 54. The fresh pears after each partition bar Ⅰ32 are driven by the conveying mechanism 3 and fall from the end of the conveyor belt 31 to the discharging plate 51 in batches. According to the sorting judgment result of the visual inspection component 4, the fresh pears are guided by the sorting plate 52 to the corresponding receiving plate 54, and finally fall into the corresponding collection box 55 under the guidance of the receiving plate 54. Pears can be sorted automatically as needed.
