1. An integrated mobile unloading and conveying device for particulate material adapted to be towed and activated by a power source, said device including:
- an elongated horizontally disposed platform;
said platform being supported at one end by a pair of retractable transport wheels, and at an opposite end by a hingedly connected hitch;
said hitch adapted to be mounted to said power source;
a rearward and a forward pair of foldable ramps;
said ramps being transverse to said platform, parallel to one another, and extending outwards from both sides of said platform;
at least one first horizontally disposed transfer conveyor located within said platform, and adapted in operation to move particulate material rearwardly within said platform;
said at least one transfer conveyor being connected by articulated joints to at least one obliquely disposed second transfer conveyor;
said at least one second transfer conveyor being connected at a remote end to a main elevating conveyor by a pivotal joint;
said second transfer conveyor in operation adapted to discharge particulate material into said main conveyor; and
said platform further including on its upper side a particulate material receiving aperture adapted to receive contents of a vehicle transporting particulate material;
said aperture being located between said forward pair and said rearward pair of ramps;
wherein in operation, when said hitch is raised at its forward end and said transport wheels are retracted, said platform is in an operating unloading position adapted to receive and convey particulate material; and
when said transport wheels are extended and said hitch is lowered at its forward end, said device can be transported to another location such that a remote end of said main conveyor can be positioned to discharge its contents into a desired storage facility.

6. A particulate material unloading apparatus adapted for attachment to an agricultural tractor for movement in an operating travel direction and for driving the apparatus, the apparatus comprising:
-
a main conveyor substantially aligned with the operating travel direction, and supported on main wheels for movement in the operating travel direction; an elongated horizontally disposed platform substantially aligned with the main conveyor and pivotally attached to a front end of the main conveyor about a substantially horizontal axis transverse to the operating travel direction such that the platform and main conveyor are maintained in substantial alignment; said platform further including on its upper side a particulate material receiving aperture; at least one retractable transport wheel supporting a rear end of the platform and a front end of the main conveyor; a hitch adapted at a front end thereof for attachment to the tractor, and pivotally attached at a rear end thereof to a front end of the platform about a substantially horizontal axis oriented transverse to the operating travel direction; a rearward and a forward pair of foldable ramps, said ramps being transverse to said platform, parallel to one another, and extending outwards from both sides of said platform; transfer means for conveying particulate material from the platform to the main conveyor; a driveline adapted at a front end thereof for connection to a power takeoff of the agricultural tractor, and extending through the platform to drive the transfer means and main conveyor; where in operation the main conveyor is maneuvered into a location as desired to discharge particulate material, a front end of the hitch is moved up and the at least one retractable transport wheel is moved up to lower the platform to rest on the ground, and the foldable ramps are extended and lowered to enable passage over the ramps of a vehicle transporting particulate material. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
