Seed sorting system

Abstract

The invention relates to a seed sorting device, which comprises a frame, a seed loading device, a sorting device and an image acquisition system. The seed loading device comprises a vibration plate and a seed loading conveyor belt mounted on the frame; both ends of the seed loading conveyor belt are respectively a seed loading terminal and a seed discharge terminal; and a lower end of a seed outlet of the vibration plate is the seed loading terminal of the seed loading conveyor belt. The sorting device comprises a sorting conveyor and a sorting chute, which are installed on the frame. The image acquisition system comprises a host computer, an upper camera and a lower camera; and the upper camera and the lower camera are installed on the frame. The seed sorting device provided by the invention utilizes a computer image processing technology to extract the shape character parameters including size, weight, shape and color of the seeds; the extracted parameters are compared with those preset by a user, so as to determine whether the seeds meet the requirements of seed breeding. The sorting device separates the seeds meeting breeding requirements from unqualified seeds, realizes the function of automatic precise seed screen, and is suitable for sorting and screening of a plurality of varieties.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a seed sorting system for sorting seeds. Background technique [0002] Seed engineering has always been the focus of economic work in various countries. The quality of crop seeds largely determines the success or failure of the planting industry, and seed breeding is an important link to ensure seed quality. During the breeding process, there are strict requirements on the size, shape, color and other characteristics of the seeds. Most of the seeds for laboratory breeding and screening in our country are manually selected. Manual selection of seeds is not only inefficient but also prone to errors due to subjective factors. At present, there are also seed automatic screening systems, but the existing automatic screening systems are all designed for a single plant variety, and can only be used for the detection and sorting of a specific si...

Manual selection of seeds is not only inefficient but also prone to errors due to subjective factors

At present, there are also seed automatic screening systems, but the existing automatic screening systems are all designed for a single plant variety, and can only be used for the detection and sorting of a specific single variety, and there is no comprehensive and universal one. A strong sorting system; and the sorting system can only complete the collection of information on one side of the seeds, but cannot complete the collection of information on both sides, and it cannot reflect the overall comprehensive information of the seeds, which may easily cause misjudgment of information; the structure of the sorting system is usually also It is relatively complicated. The existing sorting system mostly adopts the method of manipulator sorting. This structure is technically difficult to realize and the manufacturing cost is high.
