[0002] Plant dye is a natural, pollution-free, environmentally friendly dye that can be extracted from the roots, stems, leaves, flowers and fruits of plants. It can be extracted by brewing, boiling, cold soaking and acid-base methods. The extraction process is generally completed in an extraction device. According to different plant species, selecting corresponding extractants can achieve better extraction effects. The present scheme specifically relates to an environmentally friendly plant dye extraction device. When the existing environmentally friendly plant dye extraction device is used, the whole plant is directly extracted, so the extraction effect is poor. Pre-treatment of the plant in advance, that is, crushing it and then putting it into the extraction device for extraction requires additional equipment, which is troublesome. Although some extraction equipment can cut the plant, it cannot grind it, which reduces the extraction efficiency. After the extraction is completed, when the solid-liquid separation is performed, there are still a lot of plant dyes in the plant residues at the bottom that have not been separated, resulting in waste of plant dyes.
