ABSTRACT:
A light weight, inexpensive rotary drum mixing device is provided in which an essentially pear shaped drum, open at the small end and having an axially elongated socket at the large end, is rotatably supported on a unitary base having a transversely extended forward end and an upwardly and angularly extending rear end providing a bearing portion detachably engageable with said socket to rotatably support the drum at an inclination of about 35.degree., readily engageable means on the bearing portion and socket for preventing unintended axial movement, the forward end of the frame being slightly forward of the center of gravity of the rotatably supported drum to firmly support the same as drum contents are being mixed by rotation of the drum, and providing a pivot fulcrum for tilting the assemblage to discharge contents of the drum, and groove means adjacent the large end of the drum facilitating application of circumferential force to impart controlled rotation to the drum. The drum has a plurality of axially extending radial fins for lifting contents in rotation thereof and is preferably fashioned from molded plastic material either as a unitary body or as a plurality of interfitting parts.
The base is provided with an elongated extension detachably and adjustably mounted perpendicularly to the bearing portion and having means at the free end thereof for supporting a drive mechanism, including a belt drive pulley aligned with the groove means on said drum.
