Automatic detection and grading equipment for spike-shaped fruits

Abstract

The invention discloses automatic spiciform fruit detecting and grading equipment, and relates to an automatic agricultural product online undamaged detection and grading technology. The automatic spiciform fruit detecting and grading equipment comprises a conveying device, a data acquisition unit, a grading control system, a grading rejecting device and a sorting device which are sequentially connected, wherein the data acquisition unit is arranged at one side of the conveying device; the grading rejecting device is arranged at the other side of the conveying device; and the sorting device is arranged below the grading rejecting device. The automatic spiciform fruit detecting and grading equipment has the beneficial effects that a clamping mechanism of the automatic spiciform fruit detecting and grading equipment ensures the convenient feeding during hanging type conveying of fruits; the automatic spiciform fruit detecting and grading equipment is easy to operate and stable in conveying; machine vision and a spectrum technology are used for carrying out image detection and spectrum data acquisition on spiciform fruits so as to comprehensively judge and grade the external quality and internal quality of fruits, thereby overcoming the characteristics of few classification indexes and single function; the automatic rejecting device can realize the automatic grading of fruits and does not damage soft fruits; and the sorting device accelerates grading, avoids consumption of excessive human resources and improves grading efficiency.

Description

technical field [0001] The invention relates to an on-line non-destructive automatic detection and grading technology for agricultural products, in particular to an automatic detection and grading equipment for spike-shaped fruits. Background technique [0002] Spike-shaped fruits such as grapes, cherries, hawthorns, etc. have a large planting area in my country, high yield, low price and high nutritional value, and are deeply loved by ordinary people. However, the proportion of these fruits participating in the international market is very low, the export volume is small, and the price is significantly lower than that of developed countries. There are many reasons for my country's poor competitive ability, including a series of problems in fruit production, processing, storage, distribution and sales, among which the most important is the low degree of post-harvest commercialization of fruits. The experience of developed countries tells us that most of the fruit output val...

Problems solved by technology

The grading device has the characteristics of single grading index and inconvenient operation. It can only detect and classify the surface characteristics of the fruit. It is inconvenient to load the fruit and cause great damage to the fruit stem.

"Automatic grading device and method for red grapes based on machine vision (CN201210171976.6)" discloses an automatic grading device for red grapes. market requirements

"Full box red grape fruit size grading device and method based on machine vision (CN201510607956.2)" discloses a whole box red grape fruit size grading device, the research objects are all placed in the box, the fruit The stacking of fruit particles is easy to cause photo errors, and the structure is unreasonable, so it is difficult to vigorously promote

[0004] The detection and grading of the above-mentioned spike-shaped fruits either has a single function and is inconvenient to operate, or causes great damage to the fruit and has a low degree of automation. No detection and grading equipment with a reasonable structure, simple operation, and the ability to simultaneously detect the internal and external quality of spike-shaped fruits has been found.
