ABSTRACT:
An upright concrete mixing chamber having an inlet formed in the top thereof and an outlet formed in the bottom thereof is supported in a lowered position upon a horizontal working surface so as to provide operator access to the inlet when the operator is standing upon the working surface. A plurality of elongate members are pivotably connected at one end to a base member in engagement with the working surface, and at the other end are pivotably connected to the mixing chamber so as to define a parallelogram that is generally horizontal to the working surface when the mixing chamber is in the lowered position. A hinged lifting apparatus is provided for pivoting the elongate parallelogram members from the horizontal position to a second position generally perpendicular to the working surface and thereby elevating the mixing chamber to a raised upright discharge position a sufficient distance above the working surface to permit movement of a cement transport device beneath the outlet for receiving a discharge of concrete mixture therefrom. The mixing system further includes a motor for providing continuous rotary motion to blending paddles mounted in the mixing chamber, and selectively engageable means for coupling the motor to the hinged lifting apparatus to thereby cause the hinged members thereof to articulate and raise the mixing chamber to its raised upright discharge position.
