Abstract

An aggregate spreading system includes a dump truck that has a cab and a bed. The bed may contain an aggregate. A transport unit is coupled to the dump truck. The transport unit is positioned on the bed to urge the aggregate forwardly in the bed. A distribution unit is coupled to the dump truck. The distribution unit is positioned on the bed to receive the aggregate from the transport unit. Thus, the distribution unit distributes the aggregate onto a support surface. The distribution unit levels the aggregate on the support surface when the aggregate has been released onto the support surface.

said box being positionable in a deployed position having said bottom edge of said box being coextensive with and being spaced from the support surface wherein said box is configured to receive the aggregate from said chute, said box being positionable in a stored position having said box extending upwardly along said first lateral side of said bed.

10. The system according to claim 8, wherein said distribution unit further comprises a support being coupled to and extending between said first lateral wall and said second lateral wall, said support having a primary section being slidably coupled to a secondary section such that support has a telescopically adjustable length, said support being spaced from said rear wall such that said support inhibits said first lateral wall from being urged toward said second lateral wall.

11. The system according to claim 8, wherein said distribution unit further comprises a blade having a front surface, a back surface, a top edge and a lower edge, said blade being slidably coupled to said rear wall such that said back surface abuts said forward surface of said rear wall wherein said blade is configured to smooth the aggregate on the support surface when dump truck is driven along the support surface, each of said front surface and said back surface being curved such that blade curves forwardly between said top edge and said lower edge.

12. The system according to claim 11, wherein:

said rear wall has a first section and a second section; and

said blade has a first portion and a second portion, said first portion being coupled to said first section of said box, said second portion being coupled to said second section of said box.

13. The system according to claim 12, wherein said distribution unit further comprises a crank being coupled to said rear wall of said box, said crank including a handle and a screw, said screw being coupled to said top edge corresponding to said first portion of said blade such said screw raises and lowers said first portion when said handle is manipulated wherein said blade is configured to smooth the aggregate to a selected thickness on the support surface.
