Patent ID: 7540687

Claim:
An attachment for a skid steer loader comprising: (a) support frame having a width, length and height, a first and a second end with the first end being of greater width and height than the second end, and adapted to support a hopper, a conveyor system, a spreader system, a spreader system angular adjustment, a hydraulic system, at least one wheel, at least one contact roller, and a universal mounting plate; (b) a hopper for receiving construction material and directing it in a downward direction, having an open, a collapsible end, and being attached to the support frame at the first end; (c) a conveyor system attached to the support frame at the first end, at a sufficient distance beneath the hopper as to permit the conveyor system to receive construction material from the hopper and redirect it in the direction of the open end of the hopper; (d) a spreader system pivotably attached at the first end of the support frame, having two walls connected to each other to form a right angle spreader elbow, a guide rod and hydraulic cylinder and ram assembly attached to each other in a manner that permits the hydraulic cylinder and ram assembly to move the spreader elbow in the same direction as the open end of the hopper; (e) a spreader system angular adjustment having a first and a second ends pivotably attached, respectively, at the first end of the support frame and to the hydraulic cylinder and ram assembly of the spreader system as to cause the spreader system to change its angular position with respect to the support frame when the spreader system angular adjustment is activated; (f) a hydraulic system for powering the conveyor system and the spreader system, having a gear box and hydraulic motor assembly, a hydraulic cylinder and ram assembly and at least one two-way hydraulic valve and controller all attached to each other, to the support frame, and to an external hydraulic power source; (g) at least one wheel rotably attached at the first end of the support frame in a manner that maintains the first end of the support frame above ground level and permits the rolling of the support frame when it is pushed or pulled by a skid steer loader; (h) at least one contact roller rotably attached at the first end of the support frame in a manner that permits the contact roller to rotate when it comes in contact with an external wheel; and (i) a universal mounting plate attached at the second end of the support frame in a manner that allows the mounting plate to be engaged by a skid steer loader.
