Abstract
The invention is an apparatus for mixing fluent material. A hopper is pivotably mounted to a frame on a pivot axis that is substantially spaced from the axis of rotation of a mixing paddle. Because the pivot axis is substantially spaced from the axis of rotation, the mixer can be loaded by the operator at a low charge height and subsequently dumped at a higher dump height. Horizontally adjustable arms in combination with vertically adjustable legs provide for adjustability in length, width and height of the apparatus for stability when the hopper is fully dumped.
Claims3
A slurry mixing apparatus comprising:
- a. a frame having a plurality of non-wheeled, stationary feet that rest upon the ground;
- b. a hopper pivotably mounted to the frame on a single pivot axis that allows the hopper to pivot through a single path, the hopper having a chamber with an opening for receiving slurry material and wherein a rotatable mixing paddle in the hopper chamber has an axis of rotation spaced from the pivot axis a distance greater than a radius of the mixing paddle, wherein said single pivot axis is fixed relative to the frame;
- and
- c. at least one linear prime mover mounted to the frame at a first end and to the hopper at an opposite, second end, wherein the second end of the prime mover is spaced from the pivot axis to form a moment arm;
- where the hopper is adapted to rotate about the pivot axis when the prime mover is actuated after the frame is fixed relative to the feet and relative to the ground, wherein the single pivot axis is positioned within a stable base defined by the plurality of non-wheeled feed for preventing the frame from toppling over when said prime mover is fully extended and the hopper rotates about the pivot axis.
