Abstract
A manual cement mixer having a mixing box with an open top, generally planar front side and rear side panels, and arcuate, parabolically curved, right and left sides forming left and right arcuate troughs, and a medial trough disposed therebetween, the troughs defining a mixing volume; a base frame for supporting said mixing box; and pivoting means for mounting said mixing box on said base frame and for manually inducing oscillations in said mixing box.
Claims18
A manual cement mixer, comprising:
- a base frame;
- a mixing box pivotally mounted on said base frame such that oscillations can be manually induced in said mixing box, said mixing box having an open top, generally planar front side and rear side panels, and arcuate right and left imperforated side walls forming left and right imperforated arcuate troughs and an imperforated medial trough disposed therebetween, said troughs defining a mixing volume;
- wherein said right, left, and medial troughs are configured so as to induce eddies in a slurry contained therein when said mixing box is oscillated.
An oscillating manual mixer, comprising:
- a base frame;
- and
- a mixing box pivotally supported on said base frame, said mixing box including a right imperforated arcuate trough, a left imperforated arcuate trough, and a medial imperforated arcuate trough disposed between said right and left imperforated arcuate troughs, said right, left and medial imperforated arcuate troughs defining a mixing volume which contains concrete slurry during mixing;
- wherein said right imperforated arcuate trough, said left imperforated arcuate trough, and said medial imperforate arcuate trough are configured in combination so as to induce eddies in a slurry contained therein when said mixing box is oscillated.
