A motor shaft assembly includes a first shaft, a first motor, a second shaft and a second motor. The first shaft has a first end and a second end. The first motor is attached to the first end of the first shaft and is configured to rotate the first shaft about a longitudinal axis. The first shaft and the first motor have a longitudinal bore. The second shaft has a first end and a second end, wherein a portion of the second shaft is positioned in the longitudinal bore. The second motor is attached to the first end of the second shaft and is configured to rotate the second shaft about the longitudinal axis. A conveyor assembly includes a first shaft, sprocket, motor, and conveyor, and a second shaft, sprocket, motor and conveyor. An agricultural apparatus includes a tank, a boom, conveyors and motors.

An apparatus includes a shaft, a first barrel, and a second barrel. The shaft has a first end, a second end, and a longitudinal axis of rotation. The first barrel surrounds a first portion of the shaft and is fixed to the shaft to rotate therewith. The second barrel surrounds a second portion of the shaft and is configured to rotate about the axis independent of a rotation of the shaft.

The present disclosure provides a roller assembly including: a support base provided with a shaft hole; and at least two circular arc segments that are detachably mounted on the support base, wherein the at least two circular arc segments constitute a roller and a vertical distance from any point on periphery of the roller to an axis of the shaft hole is larger than a vertical distance from any point on periphery of the support base to the axis of the shaft hole. The present disclosure also provides a transmission device including a roller assembly described above.

A shunting device used to transport workpieces comprises a plurality of rotating shafts parallel to one another and arranged in arrays, a plurality of first omnidirectional wheels, and a plurality of second omnidirectional wheels. The first omnidirectional wheels and the second omnidirectional wheels are each wrapped around a corresponding one of the rotating shafts in a matrix. The first omnidirectional wheels and the second omnidirectional wheels are alternatively arranged along the corresponding one of the plurality of rotating shafts and a second direction perpendicular to the plurality of rotating shafts. A plurality of first driven rollers of the first omnidirectional wheels and a plurality of second driven rollers of the second omnidirectional wheels are mirror-symmetrical along at least one of a third direction parallel to the plurality of rotating shafts and the second direction.

An aircraft loader (54) includes an upper loading platform (50) and an underlying frame (52) with the frame utilizing the bogey suspension system (60), as well as carrying auxiliary lift system (400) at the rearward end thereof for assisting in the initial lifting of the platform relative to the frame. Powered roller assemblies (100,110,120, and 130), composed of hollow drive shafts, may be conveniently assembled and disassembled from the underside of loading platform (50). A plurality of upwardly convex-shaped static slider elements (200) facilitate unidirectional movement of loads on the platform (50). At the forward end of the platform, a guard or side rail (316) is rotatable from a retracted position within the confines of a control platform (68) to a forwardly directed position toward the fuselage of the aircraft. The side rail (316) is shaped to resemble the exterior cross-sectional shape of the fuselage, thereby to close the gap between the forward end of the loading platform and the fuselage, for the protection of loader personnel.

A feed distribution system distributes feed from a distribution vessel directly to a conveyor assembly having a belt forming a trough from which animals are fed. The system includes a distribution vessel. The distribution vessel has an output opening for distributing animal feed from the distribution vessel. A conveyor assembly extends from the distribution vessel to receive the animal feed. The conveyor assembly includes a trough conveyor which has an upper surface defining the trough from which animals may feed directly.

A modular deflection unit includes a supporting part extending in a transverse direction, at least one module support positioned along the supporting part and at least two roller modules. Roller axles of the roller modules are received and supported by the at least one module support such that the deflection unit as a whole can be modularly exchanged.
