摘要： A crushing machine having enhanced crushing efficiency. The crushing machine includes an outer casing having a fixed jaw and a movable jaw each having a crushing blade for crushing reinforced concrete. The movable jaw includes a crushing blade having a rear-side edge formed in a substantially right-angled shape with a small arcuate edge portion located at an angled edge portion thereof, and a front-side edge generally formed by a large arcuate edge portion. The rear-side edge of the movable jaw crushing blade is oriented to face in a longitudinally inward direction away from a distal end of the movable jaw. The inward orientation of the rear-side edge along with its substantially right-angled shape allow the movable jaw crushing blade to concentrate the load of the crushing machine to the small point of contact between the movable jaw crushing blade and the reinforced concrete, thereby maximizing the crushing efficiency of the crushing machine. The shape and orientation of the movable jaw crushing blade of the present invention also allows the blade to bite into the concrete, thereby preventing slippage between the blade and the concrete.

摘要： A crushing machine for crushing such as concrete structural members of buildings includes: a crushing machine outer casing; a fixed jaw body provided fixedly on the crushing machine outer casing; and a movable jaw body provided movably on the crushing machine outer casing to effect an opening and closing operation in cooperation with the fixed jaw body; wherein a crushing blade formed substantially in a shape of a semicircular cutting blade is provided at a distal end of the movable jaw body. The crushing blade includes a rear-side edge which is formed in a substantially right-angled shape with a small arcuate edge portion located at an angled portion thereof and a front-side edge which as a whole is generally formed by a large arcuate edge portion. The rear-side edge is located at a position closer to a longitudinally inward direction side of the movable jaw body relative to the front-side edge.

摘要翻译： 用于破碎的破碎机例如建筑物的混凝土结构件包括：破碎机外壳; 固定钳体，固定在破碎机外壳上; 以及可动夹爪体，其可移动地设置在所述破碎机外壳上，以与所述固定爪体协作进行打开和关闭操作; 其特征在于，在所述可动爪体的前端设置有基本上形成为半圆形切割刀片的形状的破碎刃。 破碎刀片包括后侧边缘，其形成为大致直角形状，具有位于其成角度部分处的小弓形边缘部分，并且前侧边缘通常由大的弓形边缘部分形成 。 后侧边缘相对于前侧边缘位于更靠近可动夹爪体的纵向内侧的位置。
