Automatic apple grading device capable of adjusting acquisition viewing angle

Abstract

The invention discloses an automatic apple grading device capable of adjusting an acquisition viewing angle. The automatic apple grading device capable of adjusting the acquisition viewing angle comprises a feeding unit, a conveying unit and a recognizing unit, wherein the feeding unit is arranged on the top of the automatic apple grading device capable of adjusting the acquisition viewing angle,and comprises a feeding assembly and a rotating opening and closing assembly; the conveying unit is arranged below the feeding unit, and comprises a conveying assembly and a spaced adjusting and controlling assembly; the spaced adjusting and controlling assembly comprises a second driving piece, a crank arm and a swinging piece; the second driving piece is connected with one end of the crank arm,and a slider is hinged to the other end of the crank arm; the recognizing unit comprises an acquisition assembly and an overhanging support; and the acquisition assembly is fixed to the inner side ofthe feeding assembly through the overhanging support. According to the automatic apple grading device capable of adjusting the acquisition viewing angle, due to the computer vision technology, in combination with the effects of the conveying unit and a material pushing unit, automatic recognizing and grading treatment on the appearance quality of apples can be achieved, manual work is not needed to participate in the production process, and the automatic apple grading device capable of adjusting the acquisition viewing angle is high in production efficiency and high in automation degree level.

Description

technical field [0001] The invention relates to the technical field of fruit processing, in particular to an automatic grading device for apples with adjustable collection angle of view. Background technique [0002] During the process of picking and transporting apples, the skin of apples is easily damaged by external forces, or the skin is not damaged, but the damaged surface is slightly sunken and the color is slightly darkened, which is difficult to observe with the naked eye. Bruises and abrasions are one of the main indicators of apple grading. As time goes by, the damaged part will gradually brown and eventually cause the whole fruit to rot and affect other good apples, seriously affecting economic benefits, and for merchants and buyers For the interests of both parties, it is necessary to classify apples of different qualities. [0003] In the grading standards of apples, the measurement of the fruit's shape, color, abrasion and other indicators is difficult to accu...

Problems solved by technology

However, at present, many automatic grading systems for apples do not consider the problem of individual passage during fruit transmission, and many systems still require a part of manual participation, the degree of automation is not high, and the production efficiency is insufficient.

In addition, the conveyor belt of the general automatic fruit grading system is continuously conveyed, which may easily lead to untimely sorting or wrong grading.

At the same time, many fruit automatic grading systems have a single collection environment and angle for fruit images, and the information collection is not comprehensive
