Multi-channel detection and sorting device of shriveled walnuts

Abstract

The invention relates to a multi-channel detection and sorting device of shriveled walnuts. The multi-channel detection and sorting device is composed of a feeding device, a conveying device, an online imaging detection device, an online weighing device, a speed reduction device, an airflow type grading device and a rack. Single-grain feeding is carried out simultaneously on a plurality of channels through the feeding device; the online imaging detection device is mounted above a feeding conveyor belt and walnut image information is acquired in real time; walnut quality information is acquiredin real time through the online weighing device; whether walnuts are the shriveled walnuts or not is judged through a method fusing the walnut image information and the walnut quality information; finally, the shriveled walnuts are removed by utilizing the airflow type grading device. Compared with the prior art, the multi-channel detection and sorting device can realize multi-channel online detection and sorting of the shriveled walnuts, and the commodity quality and market price of the walnuts can be improved, the labor intensity of manually sorting the shriveled walnuts is reduced and theeconomic benefits are improved.

Description

technical field [0001] The invention relates to a multi-channel detection and sorting device for shriveled walnuts, in particular to the specific detection and classification of shriveled walnuts, and belongs to the field of intelligent detection equipment for agricultural products. Background technique [0002] Walnut has high nutritional value and has both medical and health care functions. It is also known as the world-renowned "four major dried fruits" together with almonds, cashew nuts and hazelnuts. In recent years, in order to improve the quality of walnuts, domestic and foreign scholars have developed a variety of walnut detection and grading methods and equipment, the main research is as follows: Wang Wei et al. (2010) designed a 6FG-900 walnut grading machine, which can Grading according to walnut size. The classifier uses a chain to drive the classifying rollers, and the continuous stepless classifying of walnuts is realized by increasing the distance between the...

Problems solved by technology

[0007] To sum up, at present, there are many detection and grading methods for walnut quality at home and abroad, but the quality grading is only based on the size of the walnut, and the internal quality of the walnut cannot be detected. However, the internal quality of the walnut can be detected by X-ray, CT imaging and other technologies, but the cost is high. higher

[0008] Due to the characteristics of shells, walnuts have small differences in appearance and are difficult to distinguish, but they differ greatly in weight and are easy to identify
