挖掘机破碎斗与装载机区别

挖掘机破碎斗工作原理：
该系列挖掘机破碎斗的破碎方式为曲动挤压型，液压马达通过花键轴驱动偏心主轴，通过偏心轴使动颚上下运动，当动颚上升时，顶板和动颚间夹角变大，进料口的楔型空间变大，大块物料在重力作用下，向下运动，当动颚板向定锷板接近时，进料口的楔型空间变小，物料被挤压、搓、碾等多重破碎；与此同时当动颚下行时，顶板和动颚间夹角变小，挖掘机破碎斗，动颚板在拉杆、弹簧的作用下离开定颚板，此时已破碎物料从破碎腔下口排出，随着液压马达的连续转动，石子挖掘机破碎斗，破碎斗动颚作周期性的压碎和排料。
挖掘机破碎斗上颚（动颚）直接悬挂在偏心轴上，同时上颚后部用一块连接板顶在机架上。受到偏向轴的直接驱动。上颚（动颚）的后部用一块推力板支撑在机架的后壁上。当偏心轴转动时，上颚一方面对下颚作往复摆动，同时还顺着定颚有很大程度的上下运动。
挖掘机破碎斗动颚上每一点的运动轨迹并不一样，顶部的运动受到偏心轴的约束，运动轨迹接近于圆弧，在动颚的中间部分，运动轨迹为椭圆曲线，愈靠近下方椭圆愈偏长。这样随物料在重力作用下向下运动，锷板间的空间越来越小，破碎能力会越来越强。根据需要，大块混凝土物料或石料可以破碎成不同大小的颗粒，主要是依靠出料口上方的调节装置来调节出料口的大小。
Working principle of excavator crushing bucket:

The crushing mode of the crushing bucket of this series of excavators is the curved extrusion type. The hydraulic motor drives the eccentric main shaft through the spline shaft, which makes the moving jaw move up and down. When the moving jaw rises, the angle between the top plate and the moving jaw becomes larger, the wedge-shaped space of the feed inlet becomes larger, and the large material moves downward under the action of heavy force. When the moving jaw approaches the fixed force plate, the wedge-shaped space of the feed inlet changes Small, the material is crushed, rubbed, milled and other multiple crushing; at the same time, when the moving jaw goes down, the angle between the top plate and the moving jaw becomes smaller, the excavator breaks the bucket, the moving jaw leaves the fixed jaw under the action of the pull rod and spring, at this time, the crushed material is discharged from the lower opening of the crushing chamber, with the continuous rotation of the hydraulic motor, the stone excavator breaks the bucket, and the moving jaw of the breaking bucket makes periodic crushing and discharging Material.
