Navel orange classification is the first step taken after processing , the impact of the results of the hierarchical classification and subsequent processing of the sales price has greatly . Navel mechanization to achieve classification asa starting point to improve the classification accuracy as the goal, the factors affecting the navel grader pilot study to identify the main factors affecting the accuracy of classification and influence trends , research classifier for classification mechanism navel choose the optimum operating parameters , in order to further improve the structural design of the classifier to provide a theoretical basis. Navel classification is its dimensions asa standard, graded by size . Different varieties of walnuts longitudinal and transverse diameters and side diameter size was measured , and the measurement results of the statistical analysis . Based on the size classification research, in order to finalize the orange side in the radial direction size asa standard classification. Classifier using roller shaft classification method, the navel continuous stepless classification. This paper describes the characteristics of its structure and working principle , analyzed the effects of the movement and its impact on the movement speed graded orange roller shaft, the main working parts of the grading machine design study to determine the relevant
