摘要

Automatic sorting machine, by size, of beads, cores for artificial pearls and the like, which is characterized essentially by the fact that it is constituted by a general framework inside which and at one of the upper ends thereof there is arranged a rotary main drum slightly inclined and perforated on all its surface with holes of increasing diameter towards the low point of the inclination of said drum, which is located perpendicularly and on the ends of other parallel rotating drums between which are also inclined towards the extremity opposite to that occupied by said main drum, which drums are also provided with multiple orifices of increasing diameter towards that lower part of the repeated lower drums, a loading tank with a pouring hopper appearing at the higher end of said main drum. Of the granular material, being said said deposit by a chain with a conveyor of that material, appearing below the parallel drums several hoppers collectors connected to pipelines that send the material, classified according to diameters, to a pour outlets mounted on lateral stepped supports in which receiving buckets are placed, and running in charge the movement of all mentioned drums of a group of appropriate engines and transmissions.
