Portable low profile drive-over truck dump conveyor system
A portable truck dump comprises a conveyor system mounted on an elongate frame to transport material from a first end of the frame to a second, opposite end of the frame. A grate is positioned over the conveyor system and is supported by first and second sides of the frame. A ramp extends generally perpendicular to the frame on each side of the frame next to the grate to provide a drive-over access for a material transport vehicle to deposit its load over the grate and onto the conveyor system and a portion of each ramp. A first end of each ramp immediately adjacent to the frame is pivotally connected to the frame to allow the ramp to be articulated towards the grate to move excess material off of the ramp and into the grate.
1. A portable conveyor for receiving bulk material from a transport vehicle, comprising:
a belt conveyor system;
a support surface having a length and a width, a generally mid-portion of the length being positioned over a portion of the belt conveyor system, the mid-portion comprising a grate, an end portion of the support surface length being immediately adjacent to the grate;
the support surface being capable of supporting the transport vehicle to allow the transport vehicle to deposit bulk material through the grate and onto the belt conveyor system, and capable of holding any overflow bulk material that is deposited on the end portion of the support surface; and
wherein the end portion of the support surface is foldable toward the grate to move the overflow bulk material into the grate.
2. The portable conveyor of claim 1 , wherein the support surface comprises a pair of end portions, each end portion of the pair of end portions being immediately adjacent to each side of the grate.
3. A truck unloader for receiving bulk material from a transport vehicle and moving the bulk material away from the transport vehicle, the truck unloader comprising:
a drive-over surface comprising a grate and a pair of support surfaces immediately adjacent either side of the grate, the grate capable of receiving a majority of the bulk material deposited by the transport vehicle, the pair of support surfaces capable of holding any overflow bulk material deposited by the transport vehicle that does not fall through the grate;
a conveyor system located underneath the grate to receive and move the bulk material away from the transport vehicle;
wherein the pair of support surfaces are capable of folding toward the grate such that gravity moves any overflow bulk material off the support surfaces and into the grate.
