IMPROVED APPARATUS FOR AGITATING AND PUMPING A LIQUID SLURRY Abstract of the Disclosure An improved apparatus for agitating and pumping a liquid slurry, such as manure slurry. The apparatus includes a vertical column mounted for rota- tion about its axis in a pit or vessel containing the liquid slurry. A motor-pump unit is mounted for rota- tion about the axis of the column and is also mounted for vertical sliding movement relative to the column. To guide the motor-pump unit in vertical movement on the column, a generally C-shaped guide on the motor pump unit rides on a flat plate-like track on the column. The upper end of the track terminates at a level slightly above the pit, so that by elevating the motor pump unit, the motor-pump unit can be freely removed from connection with the column. The upper end of the pit is enclosed by a closure plate having a cen- tral opening, and a rotary deck plate carried by the column encloses the opening and rotates with the column relative to the closure plate. The deck plate has an aperture through which the motor-pump unit can be raised during agitation of the liquid slurry and the aperture is enclosed by a hinge cover. Extending down- wardly from the cover is a cam member which is engaged by the motor-pump unit as the motor-pump unit is ele- vated to lift the cover to an open position. The power cable which is connected to the motor-pump unit is biased upwardly by a counterweight to prevent entangle- ment of the cable when the motor-pump unit is in an upper position.
