ABSTRACT:
An apparatus for mixing powdered or premixed drywall joint compound and water to form a joint compound mixture or slurry includes a portable container rig with a container, pumping components, and mixing components on a dolly. A mixing element rests within the container upon the container bottom, while a mixing element driver assembly that is adapted to rest upon the upper lip portion of the container engages the mixing element and rotates it for mixing purposes while at the same time raising it slightly. The pumping components may include various commercially available valves and pump outlets that facilitate the filling of various tape application tools, and one preferred embodiment includes remote control components featuring automatic pump turnoff. One embodiment includes a multifunction coupling assembly having an upper coupling component and two different lower components. An operator uses the first lower coupling component when he desires to leave the mixing element in the container after mixing a batch of mud. The operator uses the second lower component when he desires to remove the mixing element from the container after mixing the batch of mud.
