SLOPE GRADING MACHINE WITH THE MECHANISM OF ACTIVE CUTTING OF SURFACE LAYER Russian patent published in 2018 - IPC E01B27/02 

FIELD: machine building.

SUBSTANCE: slope grading machine contains a working member in the form of a blade for processing the surface of the slope of the roadbed. On the dump there is a driving bar chain, one branch of which is located on the leading edge of the plow part of the blade, and the second is behind the heap outside the working area, while at the ends of the blade there is a drive sprocket in the upper part and a bypass in the lower part. Blade is fixed on a hinged frame – a parallelogram, which makes it possible to perform a plane-parallel movement up and down. Blade has a pivot axis perpendicular to the plane of the slope, which makes it possible to avoid obstacles by deflecting the blade to the required angle around this axis, without disturbing the flatness of the sloping surface being treated.

EFFECT: reduced the magnitude of the resistance to movement of the machine, as well as the mass of the working organs, increased stability of the machine, the possibility of slope grading with the bypass of the contact network supports, and a reduction in the time of production.
