A sweep auger system having a driveshaft with auger fighting and a backboard extending a length from an inward end to an outward end. An input of a gearbox is connected to an outward end of the drive shaft and a sweep wheel having a plurality of notches, arms and feet is connected to an output of the gearbox. A drive shield is placed around a rearward side of the sweep wheel that forms a channel that is configured to capture grain agitated by the drive wheel. A guide plate is connected to the gearbox and covers a portion of the gearbox. The guide plate angles from an upper outward edge downward and forward to a lower inward edge that is configured to urge the grain captured within the channel of the drive shield to move in front of the sweep auger system reducing grain left in the grain bin.

A flexible portable silo for storing grains and bulk materials, comprising a flexible cylindrical wall and a flexible conical roof made of a flexible, foldable, tension bearing sheet membrane, and a single pressure bearing post, with outriggers installed at the top of the post. The flexible cylindrical wall and conical roof are then draped over the outriggers and post and filled with grain or other bulk material.

A control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.

The disclosure describes an apparatus including a bin sweep arm, a floor support in contact with a floor surface, and a vertical adjustment assembly positioned between floor support and the bin sweep arm and connected to the floor support and the bin sweep arm, wherein the vertical adjustment assembly automatically raises the bin sweep arm off the floor surface and automatically lowers the bin sweep arm to the floor surface in response to changes in weight disposed on the bin sweep arm.

The present invention includes a method for emptying a reactor containing at least one bed of spent catalyst particles and that comprises at least one dump tube, which opens into the reactor in the bottom portion of the bed of particles or underneath the latter. The method comprises the following: a first step of causing a proportion of the catalyst bed to flow out of the reactor via said dump tube; then a second step of expelling out of the reactor the catalyst remainder, by driving towards the opening of the dump tube the catalyst particles remaining in the reactor at the end of the first step, this step being performed by means of a removable device introduced into the reactor via the dump tube,
and is characterised in that said removable device comprises an articulated arm bearing one or more protuberances spirally disposed about a rotary axis.

The disclosure describes an apparatus including a bin sweep arm, a floor support in contact with a floor surface, and a vertical adjustment assembly positioned between floor support and the bin sweep arm and connected to the floor support and the bin sweep arm, wherein the vertical adjustment assembly automatically raises the bin sweep arm off the floor surface and automatically lowers the bin sweep arm to the floor surface in response to changes in weight disposed on the bin sweep arm.

A grain dryer unload system is presented that facilitates operation of a discharge system independent of a metering system. A motor connects to an axle that connects to the discharge system, which may be a drag chain, a belt or an auger. The axle also connects to a metering system. A clutch mechanism is connected to an end of the axle and is positioned between the discharge system and the metering system. When the clutch mechanism is in an engaged position, the motor simultaneously operates the metering system and the discharge system. However, when the clutch mechanism is in a disengaged position, the motor operates the discharge system while the metering system does not operate. This arrangement facilitates easier cleaning of the grain dryer without introducing the fines into the grain or a connected grain storage device.

The invention relates to a grain sweep (1) for use on a floor comprising at least a first drive means (2), an elongated frame (3) comprising a rotatably arranged inner end (4) and an outer end (5), a drive wheel (6) adapted to rotate the elongated frame (3) around said inner end (4), and a grain moving means (7) adapted to move grain. The grain sweep (1) further comprises at least one resilient member (8) arranged at either said inner (4) or outer end (5) of said elongated frame (3), wherein the resilient member (8) allows the elongated frame (3) to move from said upper position towards a lower position when pressure is applied upon the elongated frame (3), and wherein the resilient member (8) allows the elongated frame (3) to move back towards said upper position when the pressure is removed.

A sweep auger apparatus includes an attachment plate having a first and second sides. The first side has attachment features to attach the attachment plate to mobile equipment. A first rotatable shaft is secured to the second side of the attachment plate. A central axis of the first rotatable shaft extends in a first direction. A first motor is connected to the first rotatable shaft to cause the first rotatable shaft to rotate. An auger support member is connected to the first rotatable shaft so as to rotate with a rotation of the first rotatable shaft. A second rotatable shaft is secured to the auger support member, and a central axis of the second rotatable shaft extends in a second direction that is transverse to the first direction. A second motor is connected to the second rotatable shaft to cause the second rotatable shaft to rotate, thereby rotating an auger.

A sewer and/or road cleaning vehicle is provided. The cleaning vehicle includes a dirt removal container with a central longitudinal barrel axis, container walls and a container bottom. The dirt removal container has a shape of a barrel and is arranged to accommodate and transport mineral dirt residues collected during cleaning. A clearing device is provided to empty out the dirt removal container. The clearing device includes a conveying screw and is arranged on a carrier inside the dirt removal container. The carrier is pivoted around the central longitudinal barrel axis by a pivoting drive so that the conveying screw is laterally deflected in a first and in a second direction along the container walls relative to a center position associated with the container bottom. A discharge screw assembly is arranged downstream of, and transversely to, the conveying screw to discharge the mineral dirt residues outwardly.
