Abstract

An earth moving vehicle including a scraper for collecting rocky earth and other native material to be carried upwardly by an endless paddle elevator across a grizzly for separating the material into fines and larger aggregates or tailings. The fines drop through the separator onto a continuously moving transverse conveyor adapted to discharge the fines along a line parallel to the line of vehicle movement and spaced laterally therefrom, for example in a partially filled trench for a pipeline or the like. The tailings are simultaneously discharged onto a second transversely extending continuously moving conveyor to be discharged along a longitudinal ridge, preferably on the opposite side of the vehicle from the trench being filled, and extending parallel to movement of the vehicle. The conveyors are driven by suitable motor means, preferably hydraulically actuated by pressurized fluid from a pump on the vehicle, the fluid being conducted to and from the hydraulic motors by flexible conduits wound around a sheave to maintain proper tension in the fluid lines and to avoid slack or fouling thereof, while permitting the operator to selectively adjust the discharge ends of the conveyors at desired distances laterally of the vehicle.

Claims

1. In an earth moving vehicle including a movable open front container with an earth scraper carried thereby and an endless elevator for moving native material rearwardly and upwardly from the scraper into said container, the improvement comprising:

separating means for receiving material from the elevator and separating it into fines and tailings;

carrying means receiving the fines from the separating means, and transporting and depositing the fines transversely of the direction of vehicle movement to a desired location laterally spaced from the vehicle;

resilient support means for mounting the separating means on the container, the separating means having a resiliently neutral position relative to the container; and

jarring means for periodically engaging the separating means by moving it from its neutral position and thereafter releasing it, the jarring means being mounted on the endless elevator and cyclically engaging the separating means during elevator movement.
