Intelligent fruits grading device

Abstract

An intelligent classifying apparatus for fruits is composed of an input fruit sorting-in-lines mechanism, conveying-classifying unit with conveying belt consisting of single fruit holders, supporting chain and motor, weighing unit, photoelectric switches, microprocessor, unloading controller, and discharge ports. It has high speed, precision and efficiency.

Description

technical field [0001] The invention relates to a fruit grading device, in particular to a device for grading oranges, oranges, apples, peaches and other fruits through weight detection. Background technique [0002] The main purpose of fruit grading is to make products of the same grade have the same specifications, so that they can enter the market with a uniform high-quality appearance, attract consumers' attention, and increase consumers' desire to buy. At present, the fruit is classified, mainly adopting two methods of grading by volume and grading by weight. The same fruit has the same density, and if the volume is basically the same, the weight is also about the same. [0003] The traditional devices for grading by volume mainly include drum classifiers, three-roller classifiers and belt classifiers. When it is smaller than the pore, it can rely on its own gravity to pass through or drop to output, so as to achieve classification. Due to the simplicity and practica...

Problems solved by technology

However, this classification method has the following defects: (1) The whole process of mechanical flipping and screening of fruit materials will inevitably cause bruises, abrasions and crushing on the surface of fresh fruits; (2) The classification accuracy is not high, and the level difference cannot be set too small. Can not be less than 5mm; (3) It is easy to appear the confusion of size "cascading"; (4) Poor adaptability, it is only suitable for fruits with hard skin such as oranges, but it must be used with caution for fruits with thin skin

Due to the structural problems of the spring itself, it takes a long time to return to normal after each weighing, so the output of this weighing method is low, and the accuracy of the spring is inaccurate, and the weighing error is large. Continuous work will lead to excessive fatigue of the spring, and the error will be large. Gradually increase
