DEVICE FOR IN-SOIL ROTARY MILLING WITH PERFECTED CLEANING OF MECHANICAL DRIVE OF SOIL Russian patent published in 2015 - IPC A01B33/10 A01B13/08 A01B49/02 E02F3/24 E02F5/08 

FIELD: process engineering.

SUBSTANCE: invention relates to agricultural machinery, particularly, to in-soil rotary milling and cutting of water absorbing slots in soils. This device comprises two vertical milling chisel ploughs (2). The latter are engaged with common drive. Milling chisel plough (2) is equipped with circular milling chisel plough (5). Circular milling chisel plough (5) has external cutting edges (11). The latter are made along its outer part on side surfaces, in turns at the right and left sides. Soil intake container (12) is arranged ahead of cutting edges (11). Said soil intake container (12) doubles as the recess of engagement of the driving gear of drive (15) on outer side of circular milling chisel plough (5). Said soil intake container (12) is provided with hole (13). The latter is directed perpendicular to the surface of circular milling chisel plough 5 and through its depth.

EFFECT: better cleaning of said soil intake container, lower traction resistance and higher reliability.
