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. Besides separator incorporates spring arranged on seed fraction receiver side, spring one end being jointed with the housing and another end being fixed on said support. It comprises also motor control system with its input connected with three-phase supply AC circuit. Motor is arranged opposite said intake bin to translate by it and is made up of three-phase linear induction motor. Secondary element of the latter is made up of tie rod rigidly coupled with the housing on drive side. Three-phase linear induction motor winding is connected with motor control system output.

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