挖土机的刀具 (苏联)SU1154—425—A 这种刀具有支承壳(1)和工作部(2)并配带切割边(刃)。前表面(4)具有凹入(6),它的基部(6)是属双曲线型。凹入(5)是以离切割边一定距离定位的(该距离的长度为切割边宽度的0.8—0.9) 该刀具以一定的深度插入土壤中,当它移动时将切下的泥土分离开。被分离开的泥土横过刀前边表面而移动,而且在凹入开始移动时才与刀具前表面相接触。优点:由于以一定的几何形状进行设计,该刀具在对土壤切割时所消耗的能量可节省。
Tool for excavator (USSR) SU1154-425-A This type of tool has a supporting shell (1) and a working part (2) and is equipped with a cutting edge (blade). The front surface (4) has a recess (6) and its base (6) is of the hyperbolic type. The recess (5) is positioned at a distance from the cutting edge (the length of the distance is 0.8-0.9 of the width of the cutting edge). The tool is inserted into the soil at a certain depth, and the cut soil is separated when it moves. The separated soil moves across the front surface of the knife and comes into contact with the front surface of the tool only when the recess starts to move. Advantages: Because of the design with a certain geometry, the tool can save energy when cutting the soil.
