Self-propelled and contained trailer washing machine

Claim 1

A self-propelled and contained trailer washing machine powered by an integrally assembled internal combustion engine which also concurrently drives an auxiliary electrical generator power unit and a hydraulic pump power unit respectively regulated through an integral machine drive and operational unit control console installed within a protectively enclosed driver/operator station wherein said machine is adapted to mobily straddle the lateral rectangular shaped width and height configuration of a statically positioned over-the-road commercial trailer unit body and operable to successively and selectively accomplish a sequential low-pressure spray application of washing material upon and then brushing of the opposing longitudinal sides followed by a high-pressure water spray rinsing of the rear doors continuing in a longitudinally progressive simultaneous high-pressure water spray rinsing of the top and opposing longitudinal sides and finally a high-pressure water spray rinsing of the front panel of said trailer unit body during a single self-propelled laterally straddling longitudinally displaced driven pass of said machine along said trailer unit body, said machine comprising in combination: a. an inverted U-shaped longitudinally disposed support frame structure having interconnected horizontal and vertical members assembled upon a plurality of driven wheels wherein said support frame structure is reinforced by a plurality of diagonally assembled threadably adjustable structural support brace struts, b. a low-pressure detergent material spray application means wherein an integral detergent material storage tank assembled within and carried upon the support frame structure of said machine communicates by a conduit means to the intake of a variable speed low-pressure centrifugal pump powered by a first direct current electric motor variably regulated through said machine drive and operational unit control console, further communicating through said pump to a discharge side conduit extending therefrom in the form of an inverted U-shaped arch structure having a plurality of spaced longitudinally aligned spray nozzles threadably assembled in opposing relationship thereto along the interior vertical leg members thereof, c. a low-pressure brightener material spray application means wherein an integral impervious plastic brightener material storage tank assembled within and carried upon the support frame structure of said machine communicates by a plastic conduit means to the intake of a variable speed low-pressure plastic centrifugal pump powered by a second direct current electric motor variably regulated through said machine drive and operational unit control console, further communicating through said plastic pump to a discharge side plastic conduit extending therefrom in the form of an inverted U-shaped arch structure having a plurality of spaced longitudinally aligned spray nozzles threadably assembled in opposing relationship thereto along the interior vertical leg members thereof. d. a set of laterally spaced vertically disposed rotary brushes carried upon the support frame structure of said machine and adapted to simultaneously engage and scrub the opposing longitudinal sides of said trailer while being individually and respectively arcuately deflectable unidirectionally rearward of the direction of travel of said machine about a plurality of axially aligned pivot bolts and against the resistant force of a hydraulic compression cylinder wherein each of said set of rotary brushes is provided with an arcuate deflection tensioning means being a laminated shim bearing washer respectively insertably assembled upon said axially aligned pivot bolts and compressively engaged respectively against a vertically disposed rotary brush mounting bracket by means of a nut threadably assembled respectively upon each of said pivot bolts, and e. a high-pressure water spray rinsing means wherein a plurality of conduit communicating interconnected integral water rinse storage tanks assembled within and carried upon the support frame structure of said machine communicate by a feed conduit means to the intake of at least one of a constant speed high-pressure piston pump respectively powered by a fixed speed direct current electric motor operable through said machine drive and operational unit control console, further communicating through said piston pump to a discharge side conduit extending therefrom in the form of an inverted U-shaped arch structure having a plurality of spaced longitudinally aligned spray nozzles threadably assembled thereto interior of the upper leg member and in opposing relationship thereto along the interior of the respective vertical leg members thereof.
