A single drive dual hopper conveyor system is presented having a center conveyor system and a pair of side conveyor systems that are connected to one another. A single motor is connected to the center conveyor system and drives movement of a belt within the center conveyor system. The connection of the center conveyor system to the side conveyor system causes the belts of the side conveyor systems to be simultaneously driven as the belt of the center conveyor system is driven. This arrangement eliminates the need for multiple motors. A guide at the center of the belts is configured to guide the belts through the center of the housings and prevent the buildup of grain within a cut-out section of the flights of the belt that is needed to allow access to the links of the belts to facilitate driving of the belts.

An agricultural combine including an agricultural harvester, a crop tank for harvested material, and an unloading auger assembly for unloading and discharging crop material. The auger assembly has inner and outer auger tubes pivotally connected to one another. The auger tubes pivot between a first position in which the auger tubes extend transversely and are coaxial and a second position in which the auger tubes form an angle. The auger tubes contain augers having first and second couplings at cooperating ends. The first coupling has two projections extending to cooperate with a single radial projection on the second coupling to provide improved engagement.

A method for the partial emptying of buoyant objects, which are stored in a loading aid having at least one opening is provided. A processing weight to be partially emptied is established. A fill weight is determined of the objects in the loading aid via a first weighing. The loading aid is at least partially immersed in a liquid bath. The loading aid is positioned or moved for a retention time predefined as a function of the fill weight and of the processing weight in the bath such that there is an on-average constant flow relative to the loading aid and such that the opening is disposed at least partially below a fill level surface of the bath, whereby the objects are taken along by the flow. The at least partially emptied loading aid is lifted out of the bath after the retention time has elapsed.

The object of the present invention relates to a rotating drum for infeeding material by gravity to its interior, which can be used both inside a vessel that could be subjected to pressure or not, such as for example for the treatment of solid waste with water vapour, and externally for all types of equipment that require infeeding material to a rotating drum for the transportation and tumbling thereof, wherein due to the special configuration thereof it does not require an independent device for infeeding material to the rotating drum.

A system for controlling dust during hydraulic fracturing operations includes a manifold having a plurality of ports for capturing dust when negative air pressure is applied to the manifold. A support frame positions the manifold above a piece of hydraulic fracturing equipment receiving sand from a sand source.

An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.

A container packer system includes a transfer base, which receives a container packer adapted for movement longitudinally between retracted and extended positions with respect to the transfer base. The transfer base includes a power subsystem with a motor or engine driving a hydraulic pump for powering hydraulic piston-and-cylinder units of the system, including a container packer piston-and-cylinder unit for hydraulically extending and retracting the container packer. The container packer generally encloses an interior adapted for receiving bulk material for transfer to a transport container, which can comprise a standard shipping container, a trailer or some other bulk material receptacle. The container packer includes a push blade assembly longitudinally movably mounted in its interior and actuated by a push blade piston-and-cylinder unit.

An auger assembly for transporting material for an agricultural work vehicle formed by an auger and a housing arrangement having an interior that houses the auger such that rotation of the auger within the housing arrangement is configured to transport the material through the housing arrangement. The housing arrangement includes a series of tube portions including at least a first and a second tube portion, each respective tube portion of the series of tube portions having a first and second end, an inner and outer surface, and a thickness between the inner and outer surfaces; and at least one mounting flange structure, including a first mounting flange structure secured to the outer surface of the first tube portion by a first laser weld extending from the inner surface of the first tube portion, through the thickness of the first tube portion, and into the first mounting flange structure.
