Excavator functional bucket tooth assembly capable of measuring stress
The invention particularly relates to an excavator functional bucket tooth assembly capable of measuring stress and solves the problems that a bucket tooth assembly of an existing bucket is large in soil penetrating resistance and not easy to disassemble and assemble when fractured. According to the excavator functional bucket tooth assembly capable of measuring stress, a mounting groove is formed in the groove bottom of a connecting base, and a flexible pressure sensor is fixed to an inner cavity of the mounting groove; a connecting head is arranged at the left end part of the connecting seat, the connecting head is connected with the bucket tooth through two mounting pins, the bucket tooth comprises a curved-surface convex edge, soil sliding parts are arranged on two sides of the curved-surface convex edge, and soil cutting parts are arranged at the left end parts of the soil sliding parts. The bucket tooth comprises the curved-surface rib structure with the function of reducing the soil penetration resistance; when the bucket teeth are stressed to cause deformation of the hollow cylindrical pin, the capacitance value of the flexible pressure sensor is changed, and the stress of the bucket teeth is measured.
本发明具体是一种可测受力的挖掘机功能斗齿组件，解决了现有铲斗的斗齿组件入土阻力较大、产生断裂时不易拆装的问题。一种可测受力的挖掘机功能斗齿组件，连接座的槽底部开设有安装槽，安装槽的内腔固定有柔性压力传感器；连接座的左端部设置有连接头，连接头与斗齿通过两个安装销连接，斗齿包括曲面凸棱，曲面凸棱的两侧设置有滑土部，滑土部的左端部设置切土部。本发明中斗齿包含具有减小入土阻力功能的曲面凸棱结构；当斗齿受力从而导致空心圆柱销产生变形时，柔性压力传感器电容值发生变化，对斗齿受力进行测量。
