Fluorescent marker rice seed sorting mechanism and method

Abstract

The invention provides a fluorescent marker rice seed sorting mechanism and method. The fluorescent marker rice seed sorting mechanism comprises a blanking mechanism (1), a profiling positioning mechanism (2), a conveying mechanism (3), a detection device (4), an injection mechanism (5), a collecting channel (6), a light source (7) and a frame (8), wherein the frame (8 )comprises a support frame (81), an upper positioning plate (82), a middle positioning plate (83) and a side positioning plate (84), the detection device (4) and the injection mechanism (5) in the conveying mechanism (3) are correspondingly provided with a detection station and an injection station, the collecting channel (6) is aligned with the injection station, and the light source (7) is aligned with the detection station. The fluorescent marker rice seed sorting mechanism is simple and compact in structure, convenient to use and capable of stably, uniformly and orderly loading and transporting the seeds, the detection area is wide, multiple times of detection can be carried out, and the precision of seed sorting is greatly improved.

Description

technical field [0001] The invention relates to a method for color sorting rice seeds, in particular to a sorting mechanism and method for fluorescently labeled rice seeds, in particular to a sorting mechanism and method for fluorescently labeled rice seeds with high accuracy. Background technique [0002] The selection of fluorescent protein-marked seeds is the core technology for the selection of third-generation hybrid rice varieties. When the third-generation hybrid rice seeds are harvested, red fluorescent transgenic seeds and colorless non-transgenic seeds are often mixed at a ratio of 1:1. Since the fluorescent marker imaging of transgenic rice seeds is blocked by chaff and the fluorescence effect is weakened, identification is very difficult. method cannot be identified with high accuracy. [0003] The current color sorter is mainly for sorting by visible light, and most of the sorters on the market adopt a chute structure, which has a high flux but sacrifices a cer...

Problems solved by technology

When the third-generation hybrid rice seeds are harvested, red fluorescent transgenic seeds and colorless non-transgenic seeds are often mixed at a ratio of 1:1. Since the fluorescent marker imaging of transgenic rice seeds is blocked by chaff and the fluorescence effect is weakened, identification is very difficult. The method cannot identify with high accuracy

However, this method can only achieve the screening of seed shape, and cannot sort the fluorescently labeled seeds
