Raw material devices, systems that incorporate raw material delivery devices, and methods of supplying raw material using the raw material devices. A raw material delivery device includes a hollow body comprising a first end and a second end, the second end disposed above the first end in a system vertical direction, an inlet disposed at the first end of the hollow body, an outlet disposed at the second end of the hollow body, and a stepped passageway disposed within the hollow body between the inlet and the outlet. The stepped passageway is configured to deliver raw material via one or more steps from the inlet to the outlet.

The invention relates to a grain conveyor chain for a harvesting vehicle having a chain made of standard chain elements, wherein the standard chain elements comprise inner plates, outer plates, pins and/or sleeves, and a plurality of scoops, wherein the scoops are fastened on the chain and wherein the chain has chain links, which are partially back-rigid, and to a method for operating the grain conveyor chain according to the invention in a harvesting vehicle.

The present invention relates to a vacuum conveyor for conveying granulate and/or powdery material, the conveyor comprising: a main body having an upper end and a lower end; a cavity inside the main body, said cavity comprising an opening arranged at the lower end of the main body; a valve arranged at the opening position between an open position allowing a flow of granulate and/or powdery material out from the cavity through said opening and a sealing position sealing said opening; an inlet arranged at the upper end of the main body forming an inlet passage into the cavity; a venturi inside the main body at a position being distinct from the cavity, said venturi comprising an inlet and an outlet; and a suction channel fluidly connecting the throat of the venturi with the interior of the cavity at a position at or above the inlet.

A grain bypass can be retrofit to an out auger of a grain bin. This allows for the transfer of grain, such as corn, from the grain bin to a portable auger and/or truck or other type of transfer vehicle. The grain bypass can be configured to instead divert grain down a second bypass path so as to substantially cleanout the grain bypass housing. The grain bypass includes a slide that can be inserted into the grain bypass in two separate positions so that the slide can always be contained within the system, and thus remain with the system at all times.

Conveyor pulley systems, methods and apparatus are disclosed. One or more embodiments include reinforcing structure which may comprise a cartridge. One or more embodiments include a backing bar and reinforcing disc with corresponding mounting structure.

A dual auger grain cart includes a horizontal auger assembly, a vertical auger assembly, and a drive assembly operatively connected to the horizontal and vertical auger assemblies. The horizontal and vertical auger assemblies each include an auger shaft and flighting disposed on the auger shaft. The drive assembly includes a first member operatively connected to the horizontal auger shaft, a second member operatively connected to the vertical auger shaft, and a power input device operatively connected to the first and second drive members to drive rotation of the horizontal and vertical auger shafts. The arrangement of the first and second members allow the longitudinal axes of the horizontal and vertical auger shafts to be coplanar and the vertical auger flighting to extend at least in part below the longitudinal axis of the horizontal auger shaft.

A low-profile, high-capacity elevator conveying system that is operably able to reduce spatial requirements for the elevating system to not less than about one third (⅓) of the overall lift height, and preferably having a height to base ratio in a range of between 4:1 to 8:1. The present invention also relates to a high capacity elevator conveying system which can elevate both fine and coarse materials through a range of between 300 μm and 300 mm, while limiting belt side travel to 150 mm maximum, or +/−75 mm as required to prevent edge damage to the conveyor belts.

A sweep auger shield assembly for inhibiting grain from being spilled over a sweep auger in a grain bin includes a sweep auger that has a back shield which is coupled to the sweep auger. An extension shield is provided that is mountable to the back shield of the sweep auger. Thus, the extension shield increases the overall height of the back shield. In this way the extension shield inhibits grain from passing over the back shield when the sweep auger is removing grain from a floor of a grain bin.

The invention relates to a dense-phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or similar device for spraying coating powder. The dense-phase powder pump has at least one powder conveying chamber, which is/can be fluidically connected to the first powder reservoir via a powder inlet, and to the second powder reservoir or to the powder spray-coating gun or similar device for spraying coating powder via a powder outlet. At least one powder inlet valve is provided at the powder inlet and at least one powder outlet valve is provided at the powder outlet. According to the invention, in order to make the dense-phase powder pump less prone to require maintenance during operation and, in particular, to constantly guarantee a continuous and uniform conveying of the powder, regardless of the type of powder, the at least one powder inlet valve and/or the at least one powder outlet valve has/have an effective flow cross-section in the respective open state, which corresponds to at least 35% of the effective flow cross-section of the at least one powder conveying chamber.

Systems, methods and apparatus are provided for modifying a stockpile.
