COMBINED SOIL-THROWER-FIRE-BREAK MAKER Russian patent published in 2021 - IPC A62C27/00 A62C3/02 E02F3/18 

FIELD: forestry.

SUBSTANCE: invention relates to the field of forestry, in particular to devices for preventive work aimed at preventing forest fires, as well as for actively extinguishing the edge of a forest ground fire using a mineralized soil layer. The combined soil launcher-striper contains a frame, a linkage mechanism, spherical discs with a removable cutting edge with semicircular cutouts made of separate segments and forming a soil shaft in front of the cutter-thrower, installed at the bottom of the furrow, a support wheel that regulates the level of the bottom of the furrow, a drive. The strip-laying machine additionally contains a cutting knife for cutting tree roots and protecting the cutter-thrower from large obstacles, all-edge spherical discs and a guide casing, the angle of inclination of which, and consequently the throwing of the soil flow, can be changed by means of a hydraulic cylinder. Moreover, all the spherical discs are installed on the axes of the balancers, which make it possible to copy the relief of the supporting surface. Spherical discs, which have a removable cutting edge with semicircular cutouts, trim the upper part of the forest floor, loosen large clods of soil and smooth out irregularities in the soil surface, and solid-edge spherical discs wrap the soil layer towards the center, as a result of which a furrow is created and a soil shaft is formed in front of the milling machine.

EFFECT: increasing the effectiveness of preventive work aimed at preventing forest fires, as well as actively extinguishing the edge of a forest ground fire using a mineralized soil layer.
