AI Technical Summary

Technical Problem

Existing seed sorting technologies are insufficient for multi-level sorting of Vitex negundo seeds, making it difficult to effectively separate seeds of different quality grades and to promptly remove damaged seeds and impurities, thus affecting seed preservation and quality.

Method used

A multifunctional device was designed, including a primary selection mechanism, a secondary selection mechanism, and a final selection mechanism. Through steps such as air-blowing sorting, extrusion cutting, filtration, and washing, it achieves multi-stage sorting and washing of Vitex negundo seeds. The device consists of components such as a primary sorting belt, a rubber sorting belt, a sorting roller, and a water storage tank, which are used in conjunction with a motor and an air pump to achieve automated operation.

Benefits of technology

It improves the quality and efficiency of seed sorting, effectively separates seeds of different sizes and qualities, cleans and removes impurities, extends seed storage time, and meets the requirements of GAP cultivation of medicinal plants.

Abstract

This invention provides a multifunctional device and method for sorting Vitex negundo seeds, relating to the field of seed sorting and processing technology. It includes a preliminary sorting mechanism comprising a base support, a sorting support hinged to the rear end of the base support, a storage trough at the top of the sorting support, a pair of hollow drive rollers rotatably mounted laterally on the sorting support, a preliminary sorting belt rolling between the hollow drive rollers, an inverted conical buffer port on the preliminary sorting belt, and multiple air blowing heads fixedly mounted on the outer wall of the hollow drive rollers, the air blowing heads contacting and engaging with the inverted conical buffer port. An air supply cylinder is rotatably mounted laterally inside the hollow drive rollers, with an air vent at its front end. This invention, through an adjustable-angle sorting support and adjustable-position first and second sorting baffles, can sort drupes of different sizes, improving the applicability of the equipment. Furthermore, the rubber sorting belt can separate drupes of different sizes, facilitating seed selection and improving sorting quality.
