Rotary online apple external quality detection equipment and analysis method

The invention discloses rotary apple external quality online detection equipment. Wherein the rotary conveying device, the friction plate, the photoelectric box and the blanking device are all installed on the table top of the rack, the blanking device is located on the discharging side of the rotary conveying device, the two symmetrical side baffles are arranged on the two sides of the rotary conveying device respectively, and the photoelectric box used for quality detection is located over the friction plate; the motor is installed below the table top of the rack and connected with a driving shaft of the rotary conveying device through a synchronous belt to form belt transmission. The rotary conveying device conveys the apples to the discharging side and the apples pass through the photoelectric box. When an apple to be detected is placed on the rotary fruit cup and moves to the position below the photoelectric detection box, namely the friction plate, the rotary fruit cup starts to rotate, the apple can ro
