摘要： A portable self-propelled concrete mixer vehicle. A frame assembly having parallel frame members supports a platform and a mixing barrel which extends forwardly beyond the periphery of the frame assembly. An engine and counterweight are mounted rearwardly of the barrel and on the platform so as to provide a counterbalancing force whereby the mixer can easily be tilted to unload the barrel. The engine further supplies a power source for rotating the mixing barrel and for selectively driving the mixer vehicle. A pair of ground engaging drive wheels are adapted for unidirectional rotation to prevent accidental reverse movement of the mixer vehicle. The mixing barrel has plural blades defining irregularly shaped openings with the barrel wall and are designed to mix the materials to a uniform consistency.
