Design and experiment of non-destructive grading system for strawberry suspension conveying
摘要
Abstract
To solve the problems of low efficiency in manual grading and easy damage in automated grading of fresh strawberries,a non-destructive grading system for hanging and conveying strawberries was designed.On the basis of requiring strawberry harvesting with stem left,a fruit stem clamping mechanism was designed;According to the grading function requirements,a transfer feeding mechanism,a double chain circulating conveying mechanism,and a buffer feeding mechanism were designed to achieve non-destructive conveying of strawberries.Combined with the internal and external quality inspection modules,strawberry quality grading can be achieved.The study focuses on strawberries with a diameter specification of 30～50 mm and a weight of 20～50 g.Based on the results of internal and external quality testing,they were divided into 7 grades and packaged separately.The external quality of strawberries was inspected by machine vision to extract appearance information such as strawberry size,color,shape,and other characteristic values;Internal quality was inspected by near-infrared spectroscopy to detect the content of soluble solids;According to the grading results,they were transported separately to the corresponding feeding mechanism for discharging and packaging.The research provides a new solution for the development of non-destructive grading equipment for fruits with soft and tender peel such as strawberry.关键词
