Automatic fruit grading device

Abstract

The invention relates to an automatic fruit grading device. The grading device comprises a box body, wherein the upper part of the box body is provided with an input conveying belt; the outlet of the input conveying belt is positioned above a transparent buffer basket; the transparent buffer basket is in a trumpet shape with a large upper part and a small lower part; the internal diameter of an elastic outlet on the lower part of the transparent buffer basket is smaller than the external diameter of fruits to be graded; a triangular steering device is arranged below the transparent buffer basket; the left side of the triangular steering device is positioned on a first output conveying belt, and the right side of the triangular steering device is positioned on a second output conveying belt; a rack is arranged at the bottom of the triangular steering device and is meshed with a power gear; a rotating shaft of the power gear is rotatably arranged on the box body; a spectrum camera is arranged on the side of the transparent buffer basket and is connected with an intelligent grading distinguishing module; the intelligent grading distinguishing module is connected with a control motor capable of rotating positively and negatively; the control motor is arranged on the box body; and an output shaft of the control motor is connected with the rotating shaft of the power gear. The automatic fruit grading device can reduce labor amount and improve production efficiency and reliability.

Description

technical field [0001] The invention belongs to fruit quality testing equipment, in particular to a fruit grading device. Background technique [0002] During the process of picking or transporting the fruit, the epidermis of the fruit is mechanically damaged due to external force or the epidermis of the damaged area is not damaged but the injured surface has a slight depression and a slightly darker color, which is difficult to detect with the naked eye. Bruises and abrasions are one of the main indicators for fruit grading. As time goes on, the damaged part will gradually brown and eventually cause the whole fruit to rot and affect other good fruits, seriously affecting economic benefits. In the fruit grading standard, the measurement of fruit shape, fruit surface defects, color, maturity and other indicators is difficult to accurately distinguish only by human vision, and people who use their eyes for a long time will cause visual fatigue and emotional instability, result...
