专利汇可以提供Portable self-propelled concrete mixer专利检索，专利查询，专利分析的服务。并且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.，下面是Portable self-propelled concrete mixer专利的具体信息内容。

权利要求

1. A portable self-propelled hand guided concrete mixer vehicle comprising a frame assembly having parallel frame members including hand level grasping means at one of the respective ends of the frame members for guiding movement of the mixer, the frame members depending downwardly from the grasping means toward a lower respective end of the frame members, cross members including platform means between the frame members, an axle journalled through the lower ends of the frame members, forward ground engaging wheels attached to the axle, a rearward ground engaging wheel pivotally affixed to the frame assembly, a mixing barrel rotatably supported on the frame assembly, said mixing barrel extending forwardly beyond the forward ground engaging wheels and the periphery of the frame assembly at the lower end of the frame members and having an open end for permitting access interiorally within the barrel, an integral drive shaft projecting rearwardly from an opposed closed end of the barrel, said barrel drive shaft being journalled for rotation within said platform means, an enGine mounted on the platform means and positioned on the frame assembly rearwardly of the mixing barrel, counterbalancing means including a counterweight integral with the platform for providing additional weight and stability to the mixer vehicle whereby the barrel can be optionally tilted forwardly by lifting the hand level grasping means to pivot the mixer about the axle and pour the contents from the mixing barrel, and further including drive means for transmitting power from said engine to rotate the barrel shaft and power take-off means for selectively transmitting power to said forward ground engaging wheels to thereby propel the mixer vehicle.

2. A portable self-propelled concrete mixer vehicle as claimed in claim 1 wherein the mixing barrel has a conically shaped wall being tapered toward the two opposed ends from a point of its greatest circumference, further including a plurality of spaced mixing paddles mounted longitudinally to said interior barrel wall at the point of its greatest circumference, each of said mixing blades defining an irregular shaped opening with said barrel wall whereby the materials are mixed with a uniform consistency.
