摘要： An automatically swiveling crushing apparatus has a swiveling motor in a bracket, and branches diverged from charging and discharging paths that constitute the hydraulic piping leading to a cylinder for closing or opening distal crushing arms. One of the branches extends from one of the paths then operating to open the end arms, so that a portion of the hydraulic fluid is fed to the hydraulic motor if and when internal pressure in this branch has exceeded an upper limit. The other branch extends from the other path leading to the cylinder so as to close the end arms, and this branch prevents any amount of hydraulic fluid from flowing back to the motor. The branches render dispensable a discrete or independent hydraulic piping in a self-propelled platform having a proximal working arm to be connected to the apparatus, saving cost and labor in connecting this arm to the apparatus.
摘要翻译： 自动旋转破碎装置在托架中具有旋转马达，并且分支从构成通向用于关闭或打开远端破碎臂的气缸的液压管道的充放电路径分叉。 其中一个分支从其中一个路径延伸，然后操作以打开端部臂，使得当该分支中的内部压力已经超过上限时，液压流体的一部分被馈送到液压马达。 另一个分支从通向气缸的另一路径延伸，以便关闭端臂，并且该分支防止任何量的液压流体回流到电动机。 分支机构在具有近端工作臂连接到设备的自推进平台中可分立或独立的液压管道，节省了将该臂连接到设备上的成本和劳动。
