Granular material dispersing device

The utility model discloses a particle dispersing device which comprises a feed hopper. The utility model is characterized in that a discharge port point of the feed hopper is provided with a feeding control roller, and a vibratory material dripping plate is obliquely arranged below the feeding control roller; the tail end of the vibratory material dripping plate is installed on a conveying and sampling belt, and a particle conveying groove is arranged on the vibratory material dripping plate. The device of the utility model can conveniently carry out particle dispersion for particles, and each separated particle maintain a same motion state for single-particle detection. The utility model has the characteristics of simple operation, high separating efficiency, continuous lot size, etc., and the utility model is especially suitable for the particle dispersion of an easy rolling grain class, a food class, a medicine class and other particle samples.
