Abstract
A drum-type mixer that has a cylindrical-shaped drum mounted eccentrically on a shaft that is affixed to the exterior of the drum at diametrically opposed corners of the ends of the drum. The shaft does not extend into the interior of the drum, and thus a removable drum containing the materials to be mixed can be secured inside the exterior drum during mixing operation and removed with the now-mixed contents. Other versions of the invention mount the drum and drive shaft on a pivotly mounted subframe that permits the drum to be tilted to either an upright or horizontal position for ease of loading and unloading.
Claims4
A drum-type mixer for mixing two or more materials, said mixer comprising:
- a base supporting frame for supporting the mixer, a subframe mounted on the base supporting frame and having a lower frame and an upper frame that are spaced from each other and rigidly joined together, the upper frame having a central open area, a cylindrical-shaped main drum having an exterior surface extending between two circular-shaped ends that define an interior of the drum with a longitudinal axis extending through the ends, a rotatable shaft operatively connected to the drum with the axis of rotation of the shaft at an angle to the longitudinal axis of the drum for rotating the drum eccentrically when the shaft rotates, the rotatable shaft being affixed to the exterior surface of the drum and not extending into the interior of the drum, attachment means for supporting the rotatable shaft on the upper frame with the drum positioned in the central open area of the upper frame, pivot means mounting the lower frame of the subframe to the base supporting frame to provide for pivotal movement of the subframe, and power means connected between the base supporting frame and the subframe to pivotally move the subframe and the main drum from a first mixing position to a second loading and unloading position and from the second loading and unloading position to the first mixing position.
