Abstract
Abstract An apparatus for mixing and pumping manure from a reservoir including an elongated frame adapted to be pivoted from a vehicle bed from a lying position to an upright position within a reservoir to be pumped. Pump means are provided at the base of said elongated frame communicating with a conduit extending the length of the frame, a first slurry mixing impeller adjacent the pump at the base of the frame and driven by a common shaft with the pump, a second mixing means in the form of a screw having an axis of rotation parallel to the elongated frame and having a common drive shaft with the impeller and the pump and a third mixing device in the form of a jet nozzle communicating with the pump at the base thereof and being spaced from the second mixing means. The first and third mixing means have jet nozzles directed at right angles to the axis of the elongated frame.
