A proppant delivery system for use at a hydraulic fracturing site to prepare a proppant mixture for subsequent delivery to a wellbore at the hydraulic fracturing site comprises two types of proppant storage containers, including silo type and box-like container type each of which normally has a dedicated system to dispense proppant, arranged in an array usually employed in a silo-only delivery system where parallel rows are formed and interrupted by a feed conveyor extending parallel to and disposed between the rows. A support stand carries the box-like container to one side of the feed conveyor with a bottom discharge of this container held at a spaced height above a ground surface.

Embodiments of the present disclosure include an apparatus to support a proppant container including a frame to receive and support the proppant container, the frame having a top surface that receives and positions the proppant container above a conveyor to carry proppant disposed thereon away from the proppant container. The apparatus also includes a box guide assembly positioned on the top surface including a corner assembly having two wall segments, and a guide member extending upwardly and positioned adjacent the corner assembly, the guide member including tapered portion of the guide member, the taper having a first width at a top portion of the guide member smaller than a second width at a bottom portion of the guide member. The tapered portion contacts and directs the proppant container to a desired location.

A mobile oilfield material transfer unit includes a chassis having a gooseneck and support base, the support base including a first portion and second portion, and the chassis further comprising a rear axle suspension system coupled with at least two wheels for movably supporting the chassis. The mobile oilfield material transfer unit further includes an erecting mast assembly having a mast movably connected with the chassis proximate to the second portion, and an actuator system coupled with the mast and with the chassis for moving the mast between a horizontal position and a vertical position. At least two vertical conveyor assemblies may be coupled with the erecting mast and moveable between the horizontal position and the vertical position, and at least two horizontal conveyor systems may be coupled with the support frame and engageable with the at least two vertical conveyor assemblies. Each of the at least two horizontal conveyor systems may have a horizontal section with an inlet and an inclinable section with a discharge chute. Also, each of the at least two horizontal conveyor systems may be adapted to move a volume of oilfield material from the inlet to the discharge chute.

The present invention corresponds to materials storage devices; specifically to a specialized container for the storing of granulated raw materials and its operations support base; which has been created in response to the need of storing granulated raw materials, preferably silica meant to be used in, preferably but not limited to, petroleum wells; and which is fitted with specific modifications that facilitate both the loading and discharge of said raw materials in a shorter time lapse than that displayed by conventional technologies. The invention's preferred configuration contemplates the setting up of three containers on top of the operations support base.

A bulk material shipping container unloader having an expandable supporter, a pallet receiver supported by the extendable supporter, and a material director supported by the pallet receiver.

An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.
