PROBLEM TO BE SOLVED: To provide a snow-ice crushing-mowing blade capable of efficiently crushing pressed snow and ice-snow caused on a sidewalk and a road surface in a winter season, and also usable as a mowing blade.SOLUTION: A snow-ice crushing and mowing cutting edge 14 is composed of a downward recessed substantially circular umbrella-shaped part 12, and is provided in a plurality at an equal interval in the outer peripheral vicinity of the umbrella-shaped part, and the cutting edge 14 comprises a blade-length part 16 formed over a blade tail part 14B side from an edge part 14A on the tip, and when the umbrella-shaped part 12 is contacted with a horizontal plane of becoming a reference surface, the edge part 14 is in a state of contacting or slightly floating to the horizontal plane, on the one hand, the blade-length part 16 is formed large in a clearance with the horizontal plane toward the blade tail part 14B side from the edge part 14A.COPYRIGHT: (C)2015,JPO&INPIT【課題】 冬季間は歩道や路面などに生じる圧雪、氷雪を効率的に砕くことが可能であるとともに、草刈刃としても利用することが可能な雪氷砕氷・草刈兼用刃の提供。【解決手段】 下向き凹状の略円形の傘状部12からなり、傘状部2の外周付近に雪氷砕氷用並びに草刈用の切刃14が等間隔で複数個設けられているとともに、切刃14は、先端の刃先部14Aから刃尻部14B側にかけて形成された刃渡り部16を備え、傘状部12を基準面となる水平面に接触させた場合に、刃先部14Aは、水平面に対して接触若しくは僅かに浮いた状態である一方、刃先部14Aから刃尻部14B側に向かうに従い、刃渡り部16は水平面との隙間が大きく形成されている。【選択図】 図5
