DIGGING WORKING BODY Russian patent published in 2012 - IPC A01D25/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machine industry, in particular, to machines for harvesting sugar beet roots. The digging working body comprises two cone-shaped tips attached to the ends of shafts made telescopically, and a drive of driven shafts to put them into a reciprocating motion along the axis. The drive is made in the form of two sleeves with ledges at the ends and cams in the form of a right triangle with a longitudinal gap between them. The number of cams on the mobile sleeve, fixed on the shaft by a sliding sleeve, is equal or multiple to the number of cams on the fixed sleeve rigidly mounted to the outer diameter of the fork housing. The fork ends are spring-loaded in the axial direction. At the cone-shaped tips of the fork, root-grips made in the form of 1/2 ellipsoid are mounted with the long axis along the generant of the cone.

EFFECT: invention enables to improve the efficiency of extraction of root crops while reducing their damage and reducing the load on separating working bodies.
