PNEUMATIC VIBRATION SEPARATOR Russian patent published in 2011 - IPC B07B4/00 

FIELD: process engineering.

SUBSTANCE: invention relates to agricultural machines intended for seeds cleaning. Proposed separator comprises direct-flow deck, housing with intake bin, vacuum chamber, fluidised layer divider, seed fractions receivers, and motor, swinging supports being rigidly secured to said direct-flow deck, said motor being arranged under separator bottom secured to fixed support. Proposed separator comprises single-phase frequency converter with its input connected with AC supply circuit. Motor translates linearly and is made up of three-phase linear induction motor. Separator housing makes secondary element of aforesaid induction motor. One winding of three-phase induction motor is connected with AC supply circuit, while two other windings are connected to frequency converter output.

EFFECT: higher reliability and efficiency, simplified kinematic circuit, reduced weight and sizes.
