BLADE MINE SWEEP Russian patent published in 2000 - IPC

FIELD: military engineering. SUBSTANCE: technical objective of invention lies in reduction of value of resistance force to movement of sweep. Mechanism of sweep suspension is manufactured in the form of four-bar linkage mounted for provision of pressure value of blade section on ground close to constant one and for adjustment of blade movement over entire range of longitudinal and lateral profiling. Each blade section is fitted with safety device fabricated in the form of package of restoring torsion members ensuring turning of working tool while crossing insuperable obstacle in ground and return of working tool to nominal position. Mounting of winter sweeping fixture with additional lower blade provides for sweeping of mines laid in snow and on surface of grounds having hardness above specified one. EFFECT: reduced value of resistance force to movement of sweep. 3 cl, 5 dwg
