System and method for separating and collecting cannabis

A system for separating and collecting cannabis, the system comprising:

• a frame defined by an upper end and a lower end;
• an intake chamber disposed at the upper end of the frame, the intake chamber sized and dimensioned to receive unprocessed cannabis;
• a grinding mechanism for grinding the unprocessed cannabis, the grinding mechanism comprising a housing, an intake mouth, an outlet aperture, a plurality of abrasive members;
• a tube defined by a lower end and an upper end, the tube disposed to extend at a slope from the lower end of the frame to the upper end of the frame, the upper end of the frame terminating at an elevated terminus, the elevated terminus forming a discharge outlet;
• a screw conveyor configured to operate concentrically through the tube, the screw conveyor comprising a shaft and a spiral blade configured to rotate in a helical pattern;
• a motor carried by the frame, the motor operatively connected to the screw conveyor;
• a gear mechanism carried by the frame, the gear mechanism operatively connected to the screw conveyor;
• a plurality of classifiers disposed beneath the elevated terminus of the tube, the plurality of classifiers enabling selective passage of the grinded and partially separated cannabis based on dimensions and shapes of the cannabis, the plurality of classifiers comprising a classifier base, and a classifier wall forming a classifier cavity, the plurality of classifiers further comprising a classifier mesh extending between the classifier wall, the classifier mesh defined by a plurality of mesh openings;
• a vibrating mechanism operable to shake the plurality of classifiers,
• whereby vibrating the plurality of classifiers facilitates passage of the cannabis through the plurality of classifiers;
• an ultrasonic mechanism emanating high frequency sound waves;
• a controller for controlling the high frequency sound waves emanating from the ultrasonic mechanism;
• and
• a plurality of containers carried by the plurality of classifiers.

A method for separating and collecting cannabis, the method comprising:

• loading unprocessed cannabis into an intake chamber;
• grinding the cannabis to reduce the size of the herbaceous plant material;
• carrying the cannabis upwardly through an inclined tube;
• delivering the cannabis to an elevated terminus at the upper end of the tube;
• passing at least a portion of the cannabis through a plurality of classifiers;
• shaking the cannabis at the classifiers;
• emanating high frequency sound waves towards the cannabis, or the classifiers, or both, whereby the physical shaking and impact from soundwaves dislodges oil glands, resin trichomes, and kief from the herbaceous plant material;
• and
• selectively collecting the herbaceous plant material, chaff, seeds, oil glands, and kief residue in a plurality of containers based on size or shape or both.
