Abstract
Режущий наконечник (10) механического экскаватора содержит тело (11), имеющее, по существу, заостренный дальний конец (12), ближний конец (13), расположенный на расстоянии от дальнего конца, и стенку (14), которая расходится наружу от дальнего конца к ближнему концу. Стенка (14) имеет такой профиль, чтобы оказывать неравномерное распределение нагрузки на материал, подвергающийся ударному воздействию режущего наконечника для содействия образованию радиальных трещин в этом материале. В одном варианте стенка (14) имеет профиль, чтобы включать множество ребер (15) и промежуточных областей (16), при этом ребра (15) расположены так, чтобы вызывать более сконцентрированную нагрузку в подвергающемся ударному воздействию материале, чем нагрузка, оказываемая промежуточными областями (16).A cutting tip (10) of a mechanical excavator comprises a body (11) having a substantially pointed distal end (12), a proximal end (13) located at a distance from the distal end, and a wall (14) that diverges outward from the distal end to the near end. The wall (14) has such a profile to exert an uneven load distribution on the material subjected to the impact of the cutting tip to facilitate the formation of radial cracks in this material. In one embodiment, the wall (14) has a profile to include a plurality of ribs (15) and intermediate regions (16), while the ribs (15) are arranged to cause a more concentrated load in the impacted material than the load exerted by the intermediate regions (sixteen).
