A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.

Granular material flows out through the discharge opening of a silo and through a sealed housing to a target location. A vent opening in a top portion of the silo has a vent cover operative to selectively open and close the vent opening. When the vent cover is closed, air movement into an upper portion of the silo is prevented. A gate is operative to control a flow of granular material through the discharge opening. A vacuum conduit has a lower input end thereof connected to an interior of the housing, and an upper output end thereof located in an upper portion of an interior of the silo. Material flowing out of the silo creates a vacuum drawing dust from the housing up the vacuum conduit into the silo.

A container assembly comprises a container and a base and is configured to be transported horizontally to a work site where it is raised to a vertical working orientation. A hoppered container floor directs material to a discharge opening in a center of the floor of the container. A plurality of chutes is fixed to the container assembly and each slopes downward and outward from a chute input, located under a central portion of the hoppered floor, to a corresponding chute output. A distributor assembly mounted under the discharge opening receives granular material from the discharge opening and directs same into any one of the chute inputs. When loaded on a gooseneck trailer the container extends over the hitch assembly providing increased volume and capacity.

Disclosed are methods of use for various embodiments of a vest with integrated bulk product storage. The vest may be configured to be worn about a person's neck, with a front portion and a back portion. Each of the front and back portions includes one or more integrated bulk product storage compartments. Bulk product is poured into the compartment via a reclosable filling opening at or near the top of the vest, while bulk product is dispensed from the compartment via a reclosable dispensing opening at or near the bottom of the vest. The vest may also function as a safety vest by exhibiting a safety color and/or pattern.

A proppant discharge system includes a container having an outlet formed at a bottom thereof, a gate affixed at the outlet and positioned on the floor of the container so as to be movable between a first position covering the outlet to a second position opening the outlet, a support structure having the container positioned on the top surface thereof. The support structure has at least one actuator affixed thereto. The actuator is positioned so as to move the gate between the first position and the second position. The container has a cage affixed on the floor thereof in a position over the outlet. The gate is positioned within the cage and is movable by the actuator so as to open the gate so as to allow proppant to be discharged therefrom.
