Abstract

An apparatus and process for delivering proppant to a well site has a trailer with a bed thereon and at least one track of rollers extending in parallel relationship to the longitudinal axis of the trailer. The track of rollers extend substantially for an entire length of the bed of the trailer. At least one proppant container is translatably positioned on the track of rollers. The proppant container is movable along the array of rollers from one end of the bed to an opposite end of the bed. A bin can be removably positioned below the bed of the trailer in a position rearward of the front end of the trailer and forward of a rear end of the trailer so as to allow the proppant container to discharge into the bin. A conveyor is cooperative with the bin so as to move proppant from the bin to a location at the well site.

First claim

The invention claimed is:

1. An apparatus for delivering proppant to a well site, the apparatus comprising:
a support structure having a bed for receiving a plurality of proppant containers, the support structure having one or more cross members to provide structural support for the plurality of proppant containers when positioned thereon; and
a bin positioned below one or more of the plurality of proppant containers and proximate a surface of the bed, the bin being at least partially bound by the cross members of the support structure, having one or more slanted sides to funnel the proppant downward and away from the one or more of the plurality of proppant containers, and a flow path extending through a side of the bin, the flow path positioned to allow flow of the proppant to be directed out of the bin via gravity feed.

2. The apparatus of claim 1 , further comprising conveying means positioned proximate the bin to receive proppant from one or more of the plurality of proppant containers when one or more of the plurality of proppant containers is positioned to overlie the bin and for conveying the proppant received from the bin and away from one or more of the plurality of proppant containers.

3. The apparatus of claim 2 , wherein the conveying means comprises one or more of an auger, a conveyor, and a chute.

4. The apparatus of claim 1 , further comprising wheels coupled to the support structure to facilitate movement of the support structure, and wherein the flow path of the bin is further positioned to substantially underlie an outlet of an overlying proppant container when positioned on the support structure so that proppant readily flows by gravity feed from the proppant container outlet and into the bin to be directed away from the proppant container.

5. The apparatus of claim 1 , wherein the bin is rigidly coupled to the support structure and the one or more slanted sides extend downwardly and inwardly toward the flow path.

6. The apparatus of claim 5 , wherein one or more of the plurality of proppant containers is positioned substantially centered over an inlet of the bin when positioned on the support structure and overlying the bin such that when proppant flows through an outlet in a bottom of the container the proppant is funneled along the one or more slanted sides and toward the flow path.

7. The apparatus of claim 1 , wherein the support structure comprises vertical support members arranged proximate the bin, the vertical support members being in a spaced apart relationship to form one or more openings to enable visual access to the one or more slanted sides of the bin.

8. The apparatus of claim 1 , further comprising a foot associated with the support structure, the foot being adjustable to change a horizontal orientation of the bed of the support structure.

9. An apparatus for delivering proppant to a well site, the apparatus comprising:
a support structure having a bed for receiving a plurality of proppant containers, the support structure having one or more cross members to provide structural support for the plurality of proppant containers when positioned thereon; and
a bin positioned below one or more of the plurality of proppant containers and proximate a surface of the bed, the bin being at least partially bound by the cross members of the support structure, having one or more slanted sides to funnel the proppant downward and away from the one or more of the plurality of proppant containers, an inlet positioned to substantially underlie an outlet of one or more of the plurality of proppant containers when positioned on the support structure to overlie the bin, and a flow path positioned to allow flow of the proppant to be directed out of a side of the bin via gravity feed.

10. The apparatus of claim 9 , further comprising conveying means positioned proximate the bin to receive proppant from one or more of the plurality of proppant containers when one or more of the plurality of proppant containers is positioned to overlie the bin and for conveying the proppant received from the bin and away from the proppant container.

11. The apparatus of claim 10 , wherein the conveying means comprises one or more of an auger, a conveyor, and a chute.

12. The apparatus of claim 9 , wherein the bin is rigidly coupled to the support structure, the inlet is positioned proximate the bed of the support structure, and the one or more slanted sides extend downwardly and inwardly toward the flow path.

13. The apparatus of claim 9 , wherein one or more of the plurality of proppant containers is positioned substantially centered over an inlet of the bin when positioned on the support structure and overlying the bin such that when proppant flows through an outlet in a bottom of the container the proppant is funneled along the one or more slanted sides and toward the flow path.

14. The apparatus of claim 9 , wherein the support structure comprises vertical support members arranged proximate the bin, the vertical support members being in a spaced apart relationship to form one or more openings to enable visual access to an exterior surface of the one or more slanted sides of the bin.

15. The apparatus of claim 9 , further comprising a foot associated with the support structure, the foot being adjustable to change a horizontal orientation of the bed of the support structure.
