System and method for delivering proppant to a blender
First Claim
Patent Images
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;
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 therein to direct proppant from the conveyor belt, the proppant chute to be positioned selectively at a different elevations such that proppant moving into the proppant chute exits the proppant chute at one of the selected different elevations, the pivotable joint also permitting the conveyor auxiliary unit to expand to a higher elevation when the conveyor assembly is positioned relatively close to a ground plane, thereby enabling gravity feed of proppant from the conveyor belt to the higher elevation.

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.
