Seed separation device and seed vigor non-destructive testing system

Abstract

The invention relates to the technical field of the non-destructive testing technology of seeds, in particular to a seed separation device. The seed separation device comprises a separation mechanism, a feeding mechanism and a receiving mechanism. The separation mechanism comprises an air source control box, a partial pressure box, a rotating shaft rotatably penetrating the partial pressure box, a rotating pillar connected with the lower end of the rotating shaft, and an adsorption piece arranged at the lower end of the rotating pillar. The rotating pillar is provided with a through hole communicated with a positive-pressure chamber or a negative-pressure chamber of the partial pressure box. The adsorption piece is provided with a cavity communicated with the through hole. An adsorption hole is formed in the bottom of the horizontal cavity wall of the cavity. The feeding mechanism comprises a material plate arranged below the separation mechanism, and when the adsorption hole of the adsorption piece is located above the material plate, the cavity is communicated with the negative-pressure chamber. The receiving mechanism comprises a receiving piece arranged below the separation mechanism. When the adsorption hole of the adsorption piece is located above the receiving piece, the cavity is communicated with the positive-pressure chamber, and the receiving piece is provided with an induction sensor connected with an air source controller. The invention further relates to a seed vigor non-destructive testing system comprising the separation device. Continuous and automatic singular separation of seeds is achieved.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of seeds, in particular to a seed separation device and a non-destructive detection system for seed vitality. Background technique [0002] The vigor of crop seeds is of great significance to grain production and farmers' economic benefits. Traditional methods for detecting the vigor of crop seeds mostly use biochemical methods, which are harmful to seeds, and the detection cycle is long, making it difficult for non-professionals to operate. [0003] With the development of spectral technology, the non-destructive detection of seed vigor has been realized by using hyperspectral technology or near-infrared spectroscopy technology, but the detection of seed vigor based on spectral technology only detects a single static seed, and cannot realize the dynamic detection of seeds. The equipment is large in size and high in cost, which is not convenient for the movement and popularizatio...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, the non-destructive detection of seeds cannot be automatically separated and the structure of the non-destructive detection system for seed vigor is complex and the detection efficiency is low.
