1. A system to convey proppant at a fracking site, the system comprising:

  • a conveyor auxiliary unit having a proximate end portion and a distal end portion, the proximate end portion movably connected to a conveyor assembly through a pivotable joint, the pivotable joint permitting expansion of the conveyor auxiliary unit away from the conveyor assembly and collapse of the conveyor auxiliary unit toward the conveyor assembly;

    a conveyor belt extending along at least portions of the conveyor assembly and the conveyor auxiliary unit; and

    a proppant chute positioned adjacent the distal end portion of the conveyor auxiliary unit, the proppant chute having an opening to direct the proppant from the conveyor belt into a blending hopper when positioned adjacent the distal end portion of the conveyor auxiliary unit, the proppant chute to be positioned at a higher elevation than an inlet of the blending hopper such that proppant moving into the proppant chute exits the proppant chute into the blending hopper, the pivotable joint also permitting the conveyor auxiliary unit to expand to a higher elevation than the blending hopper while the conveyor assembly is positioned relatively close to a ground plane, thereby enabling gravity feed of proppant from the conveyor belt to the blending hopper.
