1. A system for conveying proppant, the system comprising:
- a conveyor assembly having a conveyor belt and a control system to measure the flow of proppant into the blending hopper, the conveyor belt receiving proppant from one or more containers having proppant stored therein distributed along the conveyor assembly and carrying the proppant away from the conveyor system;
a conveyor auxiliary unit connected to an end of the conveyor assembly having one or more joints to enable expansion and collapse of the conveyor belt from the conveyor assembly so as further to extend along the conveyor auxiliary unit; and
a proppant chute positioned at an end of the conveyor auxiliary unit, the proppant chute having an opening to direct the proppant from the conveyor belt into the blending hopper, the proppant chute being positioned at a higher elevation than an inlet of the blending hopper such that the proppant exits the proppant chute into the blending hopper via gravity feed.

Abstract
A system for conveying proppant includes a conveyor assembly having a conveyor belt that receives proppant from one or more containers having proppant stored therein. The system also includes a conveyor auxiliary unit connected to an end of the conveyor assembly having one or more joints to enable expansion and collapse of the conveyor belt from the conveyor assembly. The system further includes a proppant chute to direct the proppant from the conveyor belt into a blending hopper, the proppant chute being positioned at a higher elevation than an inlet of the blending hopper.

9. A system to convey proppant, the system comprising:
-
a conveyor assembly to receive and support one or more containers having proppant stored therein; a conveyor belt positioned beneath the one or more containers to receive the proppant dispensed from the one or more containers and to transport the proppant away from the one or more containers; a conveyor auxiliary unit positioned at an end of the conveyor system, the conveyor auxiliary unit having an inclined section that increases a vertical position of the conveyor belt relative to a ground plane; one or more joints positioned along the conveyor assembly to enable expansion and compaction of the conveyor belt; a proppant chute positioned at the end of the conveyor auxiliary unit, the proppant chute moveable to direct the proppant away from the conveyor belt; a blending hopper positioned proximate the conveyor assembly to receive and mix the proppant with one or more proppant fluids for injection into a well; and a tub positioned at an inlet of the blending hopper between the blending hopper and the proppant chute, the tub being removable from the blending hopper and positioned at a lower elevation than the proppant chute when coupled to the blending hopper. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method comprising:
-
dispensing proppant from a container positioned on a conveyor assembly onto a conveyor belt; transporting the proppant, via the conveyor belt, away from the container and toward a conveyor auxiliary unit; adjusting an elevation of the conveyor belt via a joint of a conveyor auxiliary unit coupled to the conveyor assembly, the conveyor auxiliary unit raising or lowering the elevation of the conveyor belt relative to a ground plane; transferring the proppant to a proppant chute such that the elevation of the proppant on the conveyor belt is increased; and directing the proppant into a blending hopper via gravity feed. - View Dependent Claims (16, 17, 18, 19)
