Embodiment Construction

[0025] Taking the sorting of maize haploid seeds as an example, at present, the common method for haploid identification in various breeding institutions at home and abroad is the genetic marker method, which mainly relies on grain color marking, and uses manual methods to realize the identification and sorting of haploid seeds. Since manual selection relies on naked eye observation, it can easily lead to visual and brain fatigue, reduce efficiency and increase misjudgment, and is highly subjective, time-consuming and labor-intensive. In addition, the color marking of many materials is very weak, which will reduce the identification efficiency and the identification effect is not ideal. Therefore, in this embodiment, the patented device is used to identify and sort haploid corn seeds.

[0026] The above-mentioned haploid sorting device is divided into four parts: a seed delivery system, a near-infrared spectrum acquisition system, a near-infrared spectrum analysis system and a...

Abstract

A seed automatic identification and sorting device based on near-infrared diffuse transmittance spectra includes a feed hopper; a seed counter mounted below the feed hopper; a sample stage having the front end directly connected with an outlet of the seed counter; a light source located above the sample stage; a near-infrared spectrometer located below the sample stage; a near-infrared spectroscopic analysis system connection with the near-infrared spectrometer; a plurality of collecting containers located below the tail end of the sample stage; and a mechanical arm located above the plurality of collecting containers. The seed automatic identification and sorting device overcomes the detect that a quantitative analysis technology needs to know the certain chemical composition and content of seeds in advance, and solves the problem of a positional effect of diffuse reflection spectroscopic analysis of single-grain solid seeds, and has the advantages of automatic and rapid identification and sorting of the single-grain seeds.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment automation, in particular to a device capable of automatically identifying and sorting single seeds. Background technique [0002] In all aspects of seed breeding, seed production, processing, quality inspection, sales and use, seeds need to be identified. For example, in corn haploid breeding technology, it is necessary to identify haploid seeds; in the quality inspection of corn seeds, it is necessary to identify the purity of seeds, etc. With the advancement of science and technology, my country's agriculture is rapidly developing towards automation, engineering and modernization. The identification method of seeds is gradually moving from manual identification to machine identification, and from group seed identification to single seed identification. Compared with manual identification, machine identification is objective, fast, and accurate, which is an important guarantee fo...
