ROOT HARVESTING MACHINE Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: machine has share and plant lifter. Share is made shovel-shaped and its front part is made tray-shaped. Tray edges are continued with sides, which connect share with housing, and tray itself is continued with row bender made in the form of portion of tore surface, which is bent upward and continued with platform equipped with projection for spreading heap aside and with rearward widening recesses. Cutting edge of tray is bent outward for forming gap between tray and furrow wall to reduce friction. Plant top guides extending from ends of cutting edge are made in the form of pins directed in inclined position into feeding opening. Plant lifter has pair of disks arranged symmetrically with respect to plane of symmetry of share. Disks are mounted on shaft so that gap between disks may be adjusted and lower points of disks may rotate at zero tangential speed with respect to soil surface. Plant lifter is provided with rollers for bending and unbending of disk edges. Bending rollers are positioned rearward of shaft: one pair of rollers above platform and other pair of rollers at top part of machine. Unbending rollers are positioned forward of shaft: one pair of rollers is located at top part of machine and other pair of rollers at the level of plant tops. Machine is further equipped with fruit separators located at outer sides of disks, sleeves of polymer material equipped with fruit catchers and top remover having trough arranged between disks and traverse trough. EFFECT: simplified construction, increased efficiency and enhanced reliability in operation. 2 cl, 2 dwg
