The invention discloses cleaning and grading equipment for sugar oranges, and relates to the technical field of vegetable and fruit processing. By means of the cleaning and grading equipment, automatic cleaning of sugar oranges is achieved, and the workload is greatly relieved. Cleaning roller brushes are arranged in a staggered mode, so that a cleaning path is prolonged; the thick-bristle cleaning roller brushes and the fine-bristle cleaning roller brushes are arranged at intervals, so that the cleaning effect is good. Shower type cleaning is adopted, so that fruits are in contact with little water while the cleaning effect is guaranteed, the fruits are not likely to rot, and a powerful guarantee is provided for long-time storage. A grading roller belt is arranged, and thus fruits can be automatically classified according to the size grade. According to the scheme, the cleaning and grading equipment is characterized in that multiple cleaning roller brushes are distributed in a cleaning tank, the vertical heights of the adjacent cleaning roller brushes are different, and horizontal intervals exist between the adjacent cleaning roller brushes; an air drying device is arranged above the grading roller belt, the grading roller belt comprises multiple rollers, and an upper transmission surface is provided with a grading clamping groove belt; the grading clamping groove belt comprises two or more stages of grading sections, and each grading section comprises two or more clamping groove points. The cleaning and grading equipment is mainly used for cleaning and grading vegetables and fruits.
