A system for transporting a proppant for fracking may include a transport vehicle, a proppant container, a container clutch part, and a floating clutch part. The transport vehicle may include a carriage having forks for engaging fork pockets of the proppant container. The proppant container may house proppant releasable using a release gate and actuator. The container clutch part may be connected to the proppant container and configured to transfer rotational movement to the actuator. The floating clutch part may be connected to the carriage of the transport vehicle and configured to engage and selectively rotate the container clutch part when the forks engage the fork pockets. The forks and fork pockets vary in size which leads to a potential for misalignment between the container and floating clutch parts. The floating clutch part is vertically and laterally positionable to compensate for misalignments between the container and floating clutch parts.

A support apparatus includes a frame assembly with an elevated load surface for supporting a modular proppant container in a position above a ground level. A chute assembly is supported by the frame assembly beneath the elevated load surface. A gate actuator has a coupling configured to engage with a gate assembly of the modular proppant container supported on the elevated load surface and a drive mechanism extending between the frame assembly and the coupling to selectively position the coupling for adjusting the gate assembly. The support apparatus may include a base frame section having a recessed region beneath the elevated load surface providing a feed station, an on-board subsystem attached to the frame assembly for operating the support apparatus in a stand-alone mode or an in-situ weigh station configured to measure the weight of the modular proppant container supported on an elevated surface in the rectangular container bay.

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.

A discharge valve for discharging a food product may be arranged at a low point of a vessel. The discharge valve includes a valve body, a valve seat, a valve plug and an arm. The valve plug is attached to a first end of the arm and a second end of the arm is attached to a pivot point that is arranged inside the valve body. The arm is configured to pivot the valve plug between a valve closed position where the valve plug abuts the valve seat, and a valve open position where the valve plug is pivoted away from the valve seat, to a location where the valve plug is positioned at least partly within the valve body.

A particulate material feeding device has a particulate material storage tank for storing particulate materials, a delivery device for continuously delivering the particulate materials stored in the particulate material storage tank, a chute which drops and transfers the particulate materials delivered from the delivery device to drop and feed the particulate materials to a feeding position, a blocking body which intermittently enters a blocking position for blocking at least a part of the particulate passage in a cross-sectional direction in the chute, from a non-blocking position, and a recovery path branched from the chute so as to discharge the particulate materials blocked by the blocking body to the outside of the chute.

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.

The invention relates to a base station (10) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40), comprising a dirt path (11) through which dirt can be transported out of the dirt space (41) of the cleaning apparatus (40), wherein a path input of the dirt path (11) is formed by a coupling element (12) which can be coupled to the cleaning apparatus (40) for emptying of the dirt space (41). Furthermore, the invention relates to a cleaning system (1) and a method (100) for stationary emptying of a dirt space (41) of a mobile cleaning apparatus (40).
