    • A mixing head assembly attachable to a boom of an excavating machine comprising a torque tube supporting a motor mounted within the torque tube, and a mounting assembly for attaching the mixing head assembly to the boom of an excavating machine. The device has a rotatable mixing head supported by a drive shaft and driven by the motor, which mixing head supports mixing arms and other implements. The rotating casing of the mixing head defines a first cavity enclosing a bearing housing, which bearing housing defines a second cavity. The bearing housing is stationary with respect to the torque tube. Grease is forced through the first cavity and out a seal engaging the casing, thus keeping contaminants from the bearings. Oil is forced through the second cavity and recirculated to lubricate the bearings and prevent contaminates from entering the bearings. A water spray may be provided for suppressing dust. A header is provided for delivering dry or liquid reagents to the mixing site.
    • 混合头组件可附接到挖掘机的起重臂,该混合头组件包括支撑安装在扭矩管内的马达的扭矩管,以及用于将混合头组件附接到挖掘机的起重臂的安装组件。 该装置具有由驱动轴支撑并由电动机驱动的可旋转混合头,该混合头支撑混合臂和其它工具。 混合头的旋转壳体限定了包围轴承壳体的第一空腔,该轴承壳体限定第二空腔。 轴承座相对于扭矩管是静止的。 油脂被迫通过第一个空腔并且与外壳接合,从而保持轴承中的污染物。 油被迫通过第二个空腔并再循环以润滑轴承并防止污染物进入轴承。 可以提供喷雾用于抑制灰尘。 提供头部用于将干燥或液体试剂输送到混合部位。
