FOREST FIRE-EXTINGUISHING SOIL-THROWER-FIRE-BREAK MAKER Russian patent published in 2021 - IPC A62C27/00 A62C3/02 E02F3/18 E02F5/02 

FIELD: forestry.

SUBSTANCE: invention relates to the field of forestry, in particular to technical means for laying mineralized strips and extinguishing forest ground fires with a directed flow of soil. The forest fire ground gun-strip-laying machine contains a frame with a linkage mechanism, a screw with radial teeth and a drive from a hydraulic motor, spherical discs with a removable cutting edge with semicircular cutouts, with safety tension springs and a drive from hydraulic motors, cutters-throwers driven by hydraulic motors, guiding covers, support rollers. The auger is installed on the frame by means of struts with a movable connection, while a damping spring is installed between the frame and the auger with the possibility of adjusting the compression force and pressure of the auger on the supporting surface, and the force on the damping spring does not exceed the limiting circumferential force at the ends of the radial teeth of the auger developed by the hydraulic motor when rolling the auger over an obstacle.

EFFECT: increasing the efficiency of work by removing the soil cover with cut residues from the soil stream, improving the penetration of the spherical discs, as well as protecting the auger belt from deformation when overcoming stumps and other large obstacles.
