Abstract:
1. An all-earth foundation trencher comprising: a digger body having a blade end, a digger end, a first side, a second side and a chassis-attachment base; a track-laying chassis having a first track and a second track; a prime mover on the digger body; a control-power source on the digger body; the prime mover having power-transfer communication with the control-power source; a chassis connection in predetermined communication intermediate the chassis-attachment base on the digger body and the track-laying chassis; a control-power distributor on the digger body; the control-power source having control-power communication with the control-power distributor; the chassis connection including track directional communication of control of mobility of the first track and the second tract with a mobility controller in communication with the control-power distributor; the chassis connector including body-orientational control of orientation that includes at least verticality of the digger body in relationship to orientation of the track-laying chassis with an orientation controller in communication with the control-power distributor; an earth-mover blade on blade-control beams projected from a blade-attachment portion of the track-laying chassis; the earth-mover blade having a predetermined plurality of directional orientations controlled by a blade controller in communication with the control-power distributor; a digger boom pivotal vertically from a boom-attachment portion of the digger body; the digger boom being manipulated vertically with at least one boom-control rod having a boom controller in communication with the control-power distributor; a digger head pivotal vertically on a digger-attachment portion of the digger boom; the digger head being manipulated vertically with at least one head-control rod and the digger head having a head controller in communication with the control-power distributor; a digger backboard positioned aft of a cutter chain of the digger head for deterring loose earth from falling from the cutter chain; a compact roller positioned proximate a bottom-aft portion of the digger head; the compact roller being manipulated vertically on the digger head with at least one compaction-control rod having a compaction controller in communication with the control-power distributor; an earth conveyor positioned predeterminedly intermediate the digger head and a conveyor-attachment portion of the track-laying chassis; the earth conveyor including a first-side conveyor, a second-side conveyor and at least one central conveyor; the first-side conveyor being manipulated horizontally with at least one first-conveyor control rod having a first-conveyor controller in communication with the control-power distributor; the second-side conveyor being manipulated horizontally with at least one second-conveyor control rod having a second-conveyor controller in communication with the control-power distributor; the central conveyor being articulated for conveying earth to the first-side conveyor and to the second-side conveyor selectively with a conveyance-direction controller in communication with the control-power distributor; safety panels manipulated vertically and laterally proximate opposite sides of the digger head with safety control rods having a safety controller in communication with the control-power distributor; pile blades manipulated vertically and horizontally proximate opposite sides of the digger head with pile-control rods having a pile controller in communication with the control-power distributor; and a pilot house positioned and articulated on the digger body for forward visibility of earth-mover-blade factors and rearward for visibility of earth-digger factors from an operator seat in control-operable proximity to a control panel in operable relationship to the control-power distributor.
