A corner unit for a feed conveying system includes a housing and a wheel. The housing defines a cavity and a track. The track is configured to receive a material conveying string. The wheel is disposed at least partially within the cavity of the housing and is configured to rotate within the cavity. The housing includes a plurality of ridges protruding into the cavity. The wheel includes a central hub, an outer rim, and one or more spokes extending from a first end coupled to the central hub to a second end coupled to the outer rim. At least one of the one or more spokes is swept such that, when the wheel is rotated in a first direction, the second end trails the first end such that rotation of the wheel in the first direction sweeps material that enters the cavity from the cavity and into the track.

In the present device for moving endless conveyor chains, link conveyor chains are moved within C-shaped guides. Mounted in breaks in the guides is a chain actuating mechanism configured as two parallel chain drives. As the conveyor chains move, their rollers are engaged by drips disposed on the chain drives. The invention makes it possible to create a compact device for smoothly and evenly moving endless conveyor chains in different planes.

The present disclosure may be embodied as a belt module for a radius or spiral conveyor. The belt module includes first link ends extending in a direction of belt travel. Each first link end has a transverse opening. Second link ends extend in a direction opposite the first link ends and are configured to interdigitate with the first link ends of an adjacent belt module, and each second link end has a transverse opening defined therein. The transverse openings of the first and/or the second link ends are elongated. The belt modules further include a collapsible tab for contacting a frame member. The collapsible tab is located at a first transverse end of the belt module. In some embodiments, the collapsible tab is configured to engage a drive bar. The belt module may further include a guide tooth on a bottom side of the module for engaging a guide.

The present disclosure provides a modular belt having two or more longitudinal belt sections. Each belt section includes a traction element having a cord and a plurality of drive elements attached to the cord. The drive elements are spaced apart along a length of the cord. The belt section further includes a plurality of belt plates. Each belt plate is removably attached to a corresponding drive element of the traction element. The belt section may comprise at least one additional traction element to which each belt plate is attached. In this way, each belt plate may be attached to two or more traction elements. The modular belt includes two or more connectors, wherein each connector is configured to longitudinally couple two belt sections in order to form the modular belt as an endless belt.

An incline conveyor using a modular conveyor belt with a repeating pattern of belt sections. Each belt section includes a first region with a high-friction flat top surface, a second region with a high-friction textured top surface, a third region between the first and second regions with a recessed low-friction top surface, and a fourth region between consecutive belt sections with a top surface like that of the third region. The textured top surface, which may be formed by a plurality of nodules, provides multiple high-friction catch points to stop polybags from sliding down the inclined conveyor.

A conveyor roller turn for establishing a curved path for a conveyor chain includes a frame supporting a rail defining a curved conveyor path, and a roller body supported rotatably on the frame along the curved conveyor path. The roller body has an outside surface positioned to provide horizontal support to the conveyor drive chain. At least one bearing supports the roller body on the frame, the at least one bearing including: a plurality of ceramic rolling elements, an inner race supporting the plurality of ceramic rolling elements on a radial inner side of the bearing, an outer race supporting the plurality of ceramic rolling elements on a radial outer side of the bearing, and tungsten disulfide dry film lubricant on the ceramic rolling elements.
