Description

Technical Field

[0001] The present invention relates to the field of fruit sorting, in particular to a passion fruit sorting machine. Background Art

[0002] An existing patent (publication number: CN219292060U) proposes a sorting machine that uses a conveyor belt to transfer citrus fruits that fall from between the bottom hinged sealing plates after the bottom hinged sealing plates are opened. During the falling process, the elastic band between the two bottom hinged sealing plates provides a certain degree of cushioning. During the transfer process, the protective baffle can prevent the citrus fruits from rolling sideways; the sealing plugs of sorting holes of different sizes are opened in sequence from small to large. However, this device "opens the sealing plugs of sorting holes of different sizes in sequence from small to large, that is, small-sized citrus fruits are sorted first, and then the sorting size gradually increases." Citrus fruits of different sizes come into contact with the sorting holes simultaneously. When larger citrus fruits come into contact with the small-sized sorting holes, the surface of the citrus fruits may be bumped or damaged due to spraying, affecting the yield of the sorting process. Summary of the Invention

[0008] Beneficial effects: 1. The inner aperture of the sorting carrier sheet array group gradually increases during the forward movement of the conveying and sorting mechanism of the present invention, thereby completing the sorting of the passion fruit to be sorted placed inside the conveying and sorting mechanism. During the sorting process, the passion fruit to be sorted will only produce a small amount of sliding friction with the sorting carrier sheet in the transformation process, which will not cause bumps or damage to the surface of the passion fruit to be sorted. At the same time, the surface of the sorting carrier sheet adopts a curved splicing design, which further reduces the probability of surface damage to the passion fruit to be sorted.

[0034] It should be noted that, as the conveying and sorting mechanism 2 moves forward, the inner aperture of the array group of sorting carrier sheets 39 gradually becomes larger, thereby completing the sorting of the passion fruit to be sorted placed inside the conveying and sorting mechanism 2. During the sorting process, the passion fruit to be sorted will only produce a small amount of sliding friction with the sorting carrier sheet 39 in the transformation process, which will not cause bumps or damage to the surface of the passion fruit to be sorted. At the same time, the surface of the sorting carrier sheet 39 adopts a curved splicing design to further reduce the probability of surface damage to the passion fruit to be sorted.
