A mobile proppant delivery system may include a system for unloading proppant transport trailers, storing proppant in silos, and feeding proppant to frac operations. The system may include drive-over conveyors, swiveling distribution heads, internal silo bucket elevators, gravity feed, choke filling, and bases designed with internal conveying systems.

A linear feeder is provided that vibrates a trough to transport articles on the trough. The trough has a guiding protrusion at an intermediate position on a bottom surface of a transport path in a direction of its width. The guiding protrusion is progressively greater in lateral width in a direction of transport of the articles, and transport passages progressively smaller in width are accordingly formed at sides of the guiding protrusion.

A multi-chamber funneling hopper having at least first and second frustum-shaped containers, with the second container being disposed above the first container. The first container includes a first inwardly-sloping wall and three non-inwardly-sloping walls, the walls defining a first chamber having a first inlet and a first outlet positioned below the first inlet and of smaller area than the first inlet. The second container has a second inwardly-sloping wall and three non-inwardly-sloping walls, the walls defining a second chamber having a second inlet and a second outlet of smaller area than the second inlet and as large as the first inlet of the first container. The first container and the second container define a vertical axis passing therethrough, and the first and second containers are positioned relative to each other so that the second inwardly-sloping wall is rotated in a horizontal direction approximately ninety degrees relative to the first inwardly-sloping wall.

A storage module is provided for an organic material handling system. The storage module has a levelling component for levelling out the organic material stored therein, and a removal component for discharging the organic material. A modular system and method is described for improving the receiving, processing, storing, and transloading of bulk materials such as organic waste. A system includes at least a receiving module to receive material, a storage module, a discharge module, and a control system. Systems can be adapted with additional modules, such as processing modules and transfer modules, depending on the site and materials to be handled. A control system interfaces with the modular components and local operators, and provides remote reporting and monitoring.

A grain storage arrangement, the arrangement including: a generally box-shaped grain storage receptacle enclosing a grain receiving space; the storage receptacle including a base, a top, two opposite sidewalls, a first end wall, and a second end wall opposite the first end wall; a receptacle support, wherein the receptacle support supports the receptacle such that the base slopes downwardly from the first end wall to the second end wall; a grain inlet provided on or proximate to the first end wall for adding grain to the receptacle; and a grain outlet provided on or proximate to the second end wall for removing grain from the receptacle.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot, via the auger-based drive system, relative to grain in a grain bin. The processor is further configured to direct performance of a maintenance traversal, by the robot, of a surface of a pile of the grain during a storage period of the grain. The maintenance traversal disperses a layer of the grain on and near the surface and thus hinders crust formation on the surface during the storage period. The dispersal is effected by rotation of augers of the auger-based drive system during the maintenance traversal.
