Abstract
An improved portable, large volume cement mixer that includes a self-supporting inclined plane secured atop a wheeled main frame that provides basic structural support without the need for ancillary lifting equipment. The inclined plane is constructed in upper and lower hinged truss beams, upwardly hinged for operation and downwardly hinged for transport. A trolley carrying a cement mixer drum is then movable along the length of the inclined plane during operation, whereupon large batches of cement may be mixed and dispensed into waiting local carriers or trucks.
Claims15
A portable cement mixer for installation at selected worksites, comprising:
- a main frame wheel-supported for towed movement to a worksite;
- an inclined plane rigidly mounted rearward on said main frame and extending forward at about a 45.degree. angle;
- trolley means movable along said inclined plane between a rearward operating position and a forward dump position;
- a cement mixer drum mounted on said trolley means for controlled rotation in axially horizontal disposition;
- first hydraulic cylinder means mounted on said trolley means and actuatable to pull said trolley means and said cement mixer drum up along said inclined plane to the dump position;
- and
- second hydraulic cylinder means mounted on said trolley means for tilting said cement mixer drum forward to dump mixed cement at the dump position.
A portable cement mixer for installation at selected worksites, comprising:
- a main frame having front and rear ends that is multi-wheel supported for towed movement to a worksite;
- adjustable stabilizing means disposed about said main frame in balanced relationship;
- an inclined plane consisting of upper and lower sections hingedly connected with the lower section rigidly secured at about a 45.degree. angle to the rear end of the main frame, said upper section being foldable between a downward folded transport position and an upward folded operating position where said lower and upper sections are aligned;
- a trolley disposed on said inclined plane for movement therealong when in an operating position;
- a cement mixer drum pivotally secured to said trolley about a transverse axis with said mixer drum being rotatable;
- means for rotating the cement mixer drum at a controlled rate of revolution;
- means for moving said trolley upward along the inclined plane to a predesignated position;
- and
- means for tilting the cement mixer drum forward to a dump attitude to off-load prepared cement.
