Portable flow aid devices, systems, and methods for promoting bulk powder flow in containers. The portable flow aid devices include a housing having an enclosed internal cavity therein, and at least two vibration motors each adapted to generate vibration and each separately fixedly attached to an interior surface of the housing within the internal cavity to transmit the vibration generated thereby to the housing. Wireless communication with the portable flow aid devices causes the vibration motors to generate the vibrations and thereby apply a localized vibration to portions of a bulk powder within a container and in contact with the housing of the portable flow aid device to promote flow of the bulk powder within the container.

The invention provides a product leveling system within at least one tank or particulate material supply compartment that helps to encourage uniform movement of an agricultural product out of the bottom of the compartment. More specifically, the invention relates to a product leveling system that helps monitor areas in which agricultural product is prone to starving and also prone to accumulation, such that quantities of the agricultural product can be diverted from the areas prone to accumulation to the areas prone to starving. For instance, at least one leveling device having a driving shaft and a helical coil may be rotatably mounted within the compartment and rotated to encourage agricultural product to be moved from areas of accumulation to areas where the agricultural product is more quickly removed, resulting in starving. The product leveling system may include three coils mounted about the compartment.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. A metering conveyor is positioned between a blender tub and a proppant motive mechanism, such as a conveyor or wash system that receives discharge direct from proppant containers of the type normally used to transport sand in support of a hydraulic fracturing operation. The metering conveyor is fitted with equipment including a knife-edge gate that may be used to facilitate flow control operations.

The metering conveyor is fitted with equipment including an intermediate surge hopper with a vibration system and a knife-edge gate that may be used to facilitate the operational movement of sand.

A full floor sweep system having a skeletonized head section to facilitate removal of grain from a grain bin. The sweep system having an elongated body extending a length between an inward end and an outward end and having a leading side and a trailing side. The elongated body is connected to a pivot point at the center of the grain bin and is configured to rotate around the pivot point. An agitator is connected to the outward end of the elongated body and is configured to agitate grain as the elongated body rotates around the pivot point. The agitator includes an impeller that is connected to a shaft that extends through the elongated body. A scraper is positioned at the outward end of the elongated body and is configured to move grain into the path of the elongated body.
