A concrete mixer having a mixing drum constructed of high density crosslink polyethylene material. The drum includes a bottom supported by a conventional rigid metal pan secured to the external surface thereof to rigidify the plastic drum and extend the life expectancy of the plastic drum by enabling the concrete mixer to be used to complete a mixing job at a job site even though movement of the concrete mix within the drum during repetitive mixing cycles may ultimately wear a hole through the bottom of the plastic drum. Paddle assemblies are positioned interiorly of the drum and oriented to maintain minimum splashing during the mixing operation. A rigid ring gear is attached peripherally of the drum in spaced relation to the metal supporting pan with the drum, ring gear and metal bottom pan being uniquely related to facilitate assembly and disassembly of the components to facilitate easy replacement of the components.

Concrete mixer with plastic drum

A mortar mixer having a generally cylindrical, horizontally disposed, pivotally supported mixer drum constructed of plastic material and more specifically to improvements in the form of metal end plates attached to and rigidifying the plastic end walls of the generally cylindrical drum. The metal end plates are associated with the end walls of the plastic drum in a unique manner to reinforce and support the end walls of the plastic drum in order to provide adequate support for maintaining the shape and configuration of the generally cylindrical plastic drum during the entire procedure of placing materials to be mixed in the drum, mixing the materials and dumping the mixed materials from the drum.
