Abstract

A conveyer for particulate or comminuted material having flighting carried by a belt rather than a chain or cable. The flat belt is oriented with its broad sides in a substantially vertical plane and is driven and supported by pulleys at each end of the trough.

Claims

1. A drag type conveyor comprising a trough, flight units movably disposed transversely of said trough, flexible belt means joining and extending above said flight units, said belt means being flat and having its longer sides in a substantially vertical plane, power means in driving engagement with said belt means whereby said flight units are caused to move a material longitudinally of said trough, said power means including a driver pulley engaged with the portion of said belt means which extends above said flight units.

2. The conveyor of claim 1 in which idler pulleys are also mounted on said trough, said belt means being engaged with said idler pulleys to cause a change in direction of said belt means.

3. The conveyor of claim 1 in which said trough includes a cover part enclosing an elongated passageway, said flight units being disposed in said passage way.

4. The conveyor of claim 3 in which said cover part is formed with an elongated portion adapted to embrace said belt means whereby said belt means is guided in a particular path.
