A sweep auger system having a driveshaft with auger flighting 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.

In one aspect, the disclosure describes an apparatus comprising an auger section having an auger and a drive unit containing a motor for driving the auger. A collector ring housing containing a collector ring is positioned between the auger section and the drive unit. In another aspect, the disclosure describes an apparatus for attachment to a floor grate. The apparatus includes a pivot stand attached to a top surface of the floor grate, the pivot stand defining a vertical pivot axis. A collector ring has a first stationary portion and a second rotatable portion, with the stationary portion attached to the pivot stand. A housing surrounds the collector ring, and the housing and second rotatable portion of the collector ring rotate together about the pivot axis.

A bin sweep system for moving particulate material in a bin may comprise an elongated sweep apparatus having a particulate sweep structure configured to move particulate material on the floor beneath the sweep apparatus toward one end of the elongated sweep apparatus. The particulate sweep structure may include a plurality of interconnected paddles movable in a succession on a path along at least a portion of a length of the sweep apparatus and an endless loop member on which the paddles of the plurality of paddles are mounted at spaced locations for moving the paddles along the path. The path of the paddles on the endless loop may generally lie in a movement plane, and an orientation of the movement plane may be tilted such that the movement plane is not in a vertical orientation and not in a horizontal orientation.

A powder supply device that continuously supply a fixed amount of powder, including a powder accommodation container including a powder delivery hole in an circular outer shape bottom plate, and a disk that continuously rotates and conveys the powder by a groove facing the powder delivery hole and provided on circumference, wherein the disk is disposed to be slidably rotatable with respect to the circular outer shape bottom plate in a state in which a part of a region where the groove is located is covered with the circular outer shape bottom plate of the powder accommodation container.

The present application relates to the field of mechanical engineering technologies, and particularly to an unloading device. The unloading device includes a power mechanism, a transmission mechanism, and an execution mechanism that are connected in sequence from top to bottom; wherein the execution mechanism includes a shafting assembly and a turntable assembly that are connected in sequence from top to bottom; wherein the turntable assembly includes an upper auxiliary fence, a middle main disturbance disk, and a lower reclaiming portion that are arranged in sequence from top to bottom. The unloading device provided by the present application is easy to control, and ensures the reclaiming reliability of the spherical materials and the stability of the sphere flow unloading, which can meet the requirements of long life and reliable operation of the unloading device under light load and low speed working conditions and achieve the convenient maintenance.

A friction driven beltless grain spreader system is presented that includes a spreader cone having a pulley and a grain deflector configured to disperse the flow of grain. A motor having a driven wheel and an idler wheel are pivotally connected to the spreader cone in operative engagement with the pulley such that the idler wheel is positioned between the driven wheel and the pulley. A tension member applies a force that pulls the driven wheel and intermediary wheel into the pulley. As the motor rotates the driven wheel rotates the idler wheel which rotates the pulley. When forces spike, such as when the motor is turned on or a heavy flow of grain hits the system, one or more of the driven wheel, intermediary wheel and/or pulley slip with respect to the other wheels thereby preventing breakage of the system.

Provided is a dew condensation prevention device for a discharge chute. A tip end portion of the discharge chute has inverted truncated cone-shaped internal and external chutes, a space is provided between an outer surface of the internal chute and an inner surface of the external chute, and a first air discharge port that communicates with the space is provided between respective lower ends of the two chutes. A cylindrical portion having an air reservoir in the interior thereof is provided to surround an outer peripheral surface of the external chute, and by providing an opening between an inner peripheral edge of a lower surface of the cylindrical portion and the outer peripheral surface of the external chute, a second air discharge port that communicates with the air reservoir is provided. Air input pipes for introduction of dry air are connected to the external chute and the cylindrical portion, respectively.

A central assembly for a bin sweep apparatus having at least two sweep elements movable substantially independently of each other about the central assembly may comprise a center post and a pair of sweep interface assemblies on the center post. Each sweep interface assembly may be associated with one of the sweep elements of the bin sweep apparatus. In some embodiments, each sweep interface assembly may be configured to sense a position of one of the sweep elements.
