摘要： The grout placement apparatus has a V-shaped hopper with a flexible-bladed auger mounted therein that can be rotated in both forward and reverse directions by an auger motor. The auger has flexible blades to drive the grout material along the bottom of the hopper to a discharge sleeve that extends from the hopper. Coupled to the discharge sleeve is a discharge assembly having a flow control valve that is automatically opened and closed by the forward and reverse rotation of the auger, respectively. The discharge assembly is hingedly movable with respect to the hopper, allowing the discharge assembly to “swing away” from its operating position against the discharge sleeve to a position that uncovers the discharge sleeve for easy cleaning. A flexible discharge conduit or hose coupled to the discharge assembly conveys the grout material to the desired placement location. The rotation of the auger can be remotely controlled by a wireless remote controller, and the auger motor can be powered by the hydraulics of separate lifting equipment or by a dedicated combustion engine mounted on the placement apparatus.
摘要翻译： 灌浆放置设备具有安装在其中的具有柔性叶片螺旋钻的V形料斗，其可以通过螺旋推进器马达在前后方向上旋转。 螺旋钻具有柔性叶片，以将沿着料斗底部的灌浆材料驱动到从料斗延伸的排出套筒。 耦合到排出套筒的是具有流量控制阀的排出组件，该流量控制阀分别由螺旋推进器的正向和反向旋转自动打开和关闭。 排放组件相对于料斗可铰接地移动，允许排出组件从其操作位置“摆脱”靠在排出套筒上，使其露出排出套筒以便于清洁。 耦合到排出组件的柔性排放导管或软管将灌浆材料输送到期望的放置位置。 螺旋推运器的旋转可以由无线遥控器远程控制，并且螺旋推进器马达可以由单独提升设备的液压装置或安装在放置装置上的专用内燃机提供动力。

摘要： A bearing and seal assembly for supporting and sealing end portions of a rotatable paddle shaft in the end walls of a mortar mixer or the like. Each bearing and seal assembly includes a bearing and seal housing removably attached to an end wall of the mixer drum by bolts to facilitate replacement of the bearings and seals as becomes necessary during use. The outside wall of the housing includes a peripheral ring or shoulder for engagement with a conventional bearing puller to facilitate removal of the housing, bearings and seals as a single unit. Preassembled housing, bearing and seal units can then be used as replacements. The bearings and seals are also spaced longitudinally to provide a space for abrasive materials that may migrate past the seals to extend the life expectancy of the bearings by decreasing exposure to contamination. The housing also includes an opening in the lower portion thereof communicating with the space between the bearings and seals to enable material which migrates past the seals to fall through the opening onto the ground thereby further protecting the bearings from contamination and indicating to the mixer operator that the seals are becoming worn or have failed so that prompt maintenance or replacement may be undertaken.
