AI Technical Summary

Technical Problem

Traditional fruit sorting machines can only sort fruits with a near-spherical outer surface when sieving fruit size. Fruits with stems, such as cherries and oranges, are prone to having their stems stuck on the sorting machine, leading to misjudgment of fruit size and causing losses to consumers and merchants.

Method used

A fruit sorting machine to eliminate fruit stem interference was designed. It adopts a rotatable sorting unit and pulley structure. Through the design of the rotating shaft and the chain drive, the number of times the fruit is tumbled and the feeding speed are controlled to prevent the fruit stem from getting stuck. At the same time, the smooth and rough surfaces of the rotating shaft are used to accelerate the movement of the fruit and the friction force to achieve accurate screening of fruit size.

Benefits of technology

It effectively prevents fruit stems from getting stuck and misjudging fruit diameter, ensuring that fruits are accurately sorted according to their diameter, reducing collisions, improving sorting efficiency, and avoiding losses.

Abstract

This application discloses a fruit sorting machine that eliminates stem interference, belonging to the field of sorting technology. It includes a frame, a gearbox, a limiting plate, and a sorting unit. A swing seat is provided on the frame, and the gearbox and the limiting plate are fixedly connected. The input end of the gearbox is drively connected to the output shaft of a motor. This fruit sorting machine solves the technical problem in traditional fruit sorting where, when sieving fruit size, the sorting machine can only sort fruits with a nearly spherical outer surface. Fruits with stems, such as cherries, oranges, and mangosteens, are prone to stem jamming against the sorting machine, causing misjudgment of the fruit's size and resulting in losses for consumers and merchants.
