Abstract: The disclosure provides a method for detecting a pomelo flesh mass edible ratio based on X-ray images: acquiring X-ray images A of a pomelo in a vertical direction and a transversal direction; performing noise reduction and grayscale stretching to obtain enhanced X-ray images B; processing the enhanced X-ray images B to obtain vertical and transversal 2D flesh masses; building a prediction model of an actual pomelo flesh mass; inputting the vertical and transversal 2D flesh masses into the prediction model to obtain a predicted flesh mass; weighting a fruit mass of the entire pomelo; and calculating a pomelo fruit edible ratio. The pomelo flesh mass is detected in a non-destructive manner in the disclosure through the combination of X-ray images and image processing technology, so rapid detection that saves time and labor costs is achieved. The accuracy of predicting the pomelo flesh mass is improved.

Abstract: A roller-type conveying device for fruit and vegetable sorting includes a chain assembly and a conveying unit. Fruits and vegetables are placed on the conveying unit. The chain assembly includes a drive chain and a chain support bar, and the drive chain is arranged on the chain support bar. A conveying unit is arranged along a drive chain. The conveying unit includes outer rollers, a roller frame, pin shafts, rubber bushings, a roller shaft, and a support base. The two outer rollers are fixed coaxially on the two ends of the roller shaft. The roller shaft is equipped with the rubber bushing. The roller shaft is movably fitted into a special-shaped hole slot on the top of the roller frame. The roller shaft is arranged axially perpendicular to the transmission direction of the drive chain. The support base is mounted on the drive chain.
