1. A method, comprising:
extending a concrete residue collection system from a stored position to an extended position beneath any utilized pouring chutes of a concrete mixing truck, wherein the concrete residue collection system collects slurry aggregate from the concrete mixing truck, wherein the concrete residue collection system further comprises:
a collection hopper;
an augur conveyor connected to the collection hopper, the augur conveyor further comprising:
a casing tube having an augur conveyor inlet and an augur conveyor outlet;
a helical screw disposed within the casing tube of the augur conveyor, wherein the helical screw extends from the augur conveyor inlet to the augur conveyor outlet, wherein an outlet of the collection hopper leads to at least the augur conveyor within the casing tube;
an extension platform, wherein the collection hopper and connected augur conveyor are attached to the extension platform;
one or more hydraulic cylinders connecting the casing tube of the augur conveyor to the extension platform;
a motor housing that houses a motor;
when ready for operation and reclamation of the slurry aggregate by the concrete residue collection system, extending the extension platform in a horizontal direction away from the concrete mixing truck and raising the casing tube of the augur conveyor to a full height until the casing tube of the augur conveyor is raised to a maximum angle away from the extension platform and the augur conveyor outlet is positioned over a top hopper of the concrete mixing truck;
powering the helical screw to rotate within the casing tube of the augur conveyor in order to have a rotating helical screw within the casing tube that extends from the augur conveyor inlet to the augur conveyor outlet;
activating a water source and flushing any slurry aggregate collected on the any utilized pouring chutes of the concrete mixing truck into the collection hopper of the concrete residue collection system, wherein the slurry aggregate flowing off of the any utilized pouring chutes is directed through an interior cavity of the collection hopper and into the augur conveyor inlet located on a lower end of the casing tube;
flowing the slurry aggregate in an upwards direction upwardly through the casing tube by means of the rotating helical screw within the casing tube of the augur conveyor towards the augur conveyor outlet;
discharging the slurry aggregate from the augur conveyor outlet through a connected discharge pipe or tube or other discharge assembly into an inlet of the top hopper of the concrete mixing truck;
flowing the slurry aggregate from the connected discharge pipe or tube or other discharge assembly into the inlet of the top hopper of the concrete mixing truck and into a mixing drum of the concrete mixing truck;
upon completion of reclamation of the slurry aggregate within the mixing drum of the concrete mixing truck, preparing the concrete residue collection system to return to the stored position, further comprising:
lowering the casing tube of the augur conveyor until the casing tube is substantially horizontal and parallel to and/or contacting a top surface of the extension platform; and
after lowering the casing tube of the augur conveyor, retracting the extended extension platform by retracting the extended extension platform in a horizontal direction towards the concrete mixing truck; and
transporting the slurry aggregate on the concrete mixing truck to another location for subsequent disposal or use.
