SEPARATING MODULE FOR TRANSFORMING POTATO DIGGER INTO ROOT HARVESTER Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: module has centrifugal-squeezing separator, belt-inertial top remover, and discharge conveyor. Assembling units are mounted on detachable base constructed and sized in accordance with top contour of serial digger frame. Second stage of centrifugal-squeezing separator is arranged in front part of base and composed of two rod-type elevator webs. One of webs is running around front part of wheels, which are mounted on common shaft and equipped with annular guiding track and toothed gear, which comes into contact with elevator rods. Elevator upper free branch is inclined to horizontal plane to define acceleration surface and is put onto guiding roll fixed to upper end of levers pivotally connected to frame. Levers are fixed in predetermined position on section having plurality of openings. Second elevator of smaller width is put onto rings arranged on wheel disks in circular path concentric to wheel rim and onto sprockets of upper shaft mounted under drive shaft of separator first stage. Module is preferably used on water-logged soils. EFFECT: increased efficiency and wider operational capabilities. 2 cl, 1 dwg
