A container adapter for securing a container to a cargo section of a vehicle includes a frame, a plurality of brackets connected to the frame for securing the frame to the cargo section, and a plurality of locks formed on the frame configured to secure the frame to the container. The cargo section of the vehicle includes one or more attachments secured to a support surface, and at least two locks disposed on the attachments and spaced apart by a predetermined distance in a length direction. The at least two locks configured to engage the one or more containers. A trailer includes a cargo section having multiple bolsters, for use in the sand haul operation for example, the multiple bolsters including first, second and third bolsters spaced apart along a length direction, each bolster comprising two locks configured to engage a container. The second bolster is spaced from the first bolster by a first distance and the third bolster spaced from the first bolster by a second distance different than the first distance.

A grain spreader includes a hopper and spreader arms that distribute grain in a bin with a spreader cone having convergent divergent cones. The convergent cone forms a first flow zone. A center opening between the convergent cone and divergent cone allows a first portion of grain collecting in the convergent cone to pass through the spreader cone. An intermediate funnel is inside the hopper body between the convergent cone and the hopper body. A second portion of the grain spills over the rim of the convergent cone and onto the divergent cone into a second flow zone outside the convergent cone but inside the intermediate funnel. When the second zone fills with grain, a further portion of grain will spill over a rim of the intermediate funnel into a third flow zone radially outward of the intermediate funnel but inside the hopper body.

A bulk fluid storage container has a top wall structure and a bottom wall structure held in spaced relation by a side wall structure. An internal baffle assembly is disposed in the fluid storage volume between the side wall structure for reducing fluid sloshing. A fill port formed in the top wall structure has a fill flange for coupling with a source of the fluid. A vent port formed in the top wall structure has a pressure vacuum value. A drain port formed in the side wall structure in a lower region adjacent the gutter region has a drain valve assembly is coupled to the drain port. A frame assembly includes an upper rectangular frame member and a lower rectangular frame member arranged in spaced relation by a plurality of post; wherein the frame assembly surrounds and supports the fluid storage vessel.

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.

The invention discloses a liquid conveying system, a liner bag and a manufacturing method. The liner bag comprises a liner bag body and a discharge port, the liner bag body is formed by sealing and welding a front panel and a rear panel along the periphery, and the discharging port is sealedly connected with the liner bag body. The liner bag body is substantially rectangular, and the liner bag body has two pairs of opposite side edges, and corresponding adjacent side edges of the two pairs of opposite side edges are connected by one or more transition edges The liner bag of the invention is simple to manufacture and does not form a damming lake during the liquid discharge process, which is especially beneficial for the discharge of viscous liquid, and less liquid remains after the discharge is completed.
