Abstract

An earth handling apparatus operable in a trailered manner behind an ATV includes a rolling framework containing a tiltable accumulating bowl having a pivotable front door. Winch devices operated by the electrical system of the ATV control the tilting of the framework, the bowl and the front door to enable the bowl to accumulate, transport and controllably discharge earth, sand, gravel, snow or other surface substrate.

Claims10

Dependent claims

An earth handling apparatus operated by an all-terrain vehicle, said apparatus comprising:

a) a rolling framework comprised of elongated rigid front and rear frame members and paired side frame members, said four frame members being joined in a coplanar rectangular configuration defining an interior region and with portions of said side frame members extending as rearward extensions behind said rear frame member, and a trailer hitch bar extending forwardly from the center of said front frame member,
b) a wheel axially journaled to each rearward extension of said side frame members, and adapted to rotate in a vertical plane, thereby supporting said framework for rolling movement upon underlying terrain,
c) an accumulating bowl positioned within the interior region of said framework and bounded by floor, rear and paired side retaining surfaces and a front door pivotable between an upper, open state and lower, closed state, said floor surface having a forwardly directed cutting edge, said bowl being supported by said framework by way of pivot means interactive between said side retaining surfaces and corresponding side frame members to permit tilting movement of said bowl in a vertical path parallel to said side frame members,
d) tilting means comprised of a first electrically operated winch associated with said front frame member, a rigid boom attached to said front frame member and extending above said bowl, and a pulling cable interactive between said winch and rear retaining surface and guided by said boom to achieve said tilting movement of said bowl between a horizontally disposed state which permits earth to enter and be transported by said bowl, and an obliquely angled state which permits dumping of earth from said bowl,
e) a second electrically operated winch for moving said front door to said open state to permit earth to enter said bowl and to said closed state to secure the earth during transport, and
f) a third electrically operated winch interactive between said hitch bar and said all terrain vehicle to control the elevation of said bowl above said terrain.
