AERODYNAMIC MIXTURE SEPARATOR Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: separator has conveyor 1 with driven upper branch making working run 2 and pneumatic pressure conduits positioned below working branch 2 and provided with blowers 3, and pneumatic suction conduit with cover 4 positioned above working run 2 of conveyor 1. Mixture 5 delivered onto working run 2 is exposed to the action of pneumatic flows forced from the bottom to the top through pneumatic conduits with blower 3. During separation mixture 5 obtains wavy structure, separated soil 6 is sieved and falls under conveyor and separated roots 7 exit from working run 2 of conveyor 1. EFFECT: increased efficiency, reduced production and maintenance cost, wider operational capabilities by efficient operation in wet weather on superwet and heavy soils, simplified construction and reduced dimensions. 1 dwg
