FIELD: agricultural engineering. SUBSTANCE: elevator has rod surface mounted on drive and supporting members, crumble destructing device with flexible working surface and disk flanges axially aligned with said device and contacting with elevator rib surface to define embracing angle. Elevator is further provided with spring-loaded rollers disposed under arced portion of rib surface. Crumble destructing device is made in the form of blade-type beater. Beater to flange diameter ratio is 1.2-1.5. Flange is mounted on pin for free rotation thereon. Each of blades is bent rearward relative to direction of rotation and is equipped with shock-absorbing member positioned at rear side blade base and is provided with radial slots extending along the entire width of outer edge. EFFECT: increased efficiency, enhanced reliability in operation, improved soil separation and reduced damage to roots. 5 cl, 4 dwg
