Prior known enclosed conveyors have had a conventional belt conveyor mounted on a structural framework resting on a series of support columns known in the art as bents. A housing or gallery, as it is known in the art, consisting of a roof, side walls and optionally a floor, is constructed on structural members around the conveyor covered by a protective material. Often times, the housing is large enough to accomodate a walk-way alongside the conveyor. In each instance, however, both the housing and the conveyor are supported by structural members and not by the protective covering material of the housing. There have been instances of short spans of enclosed conveyors using solid longitudinal members as side and top walls as well as for support, but these spans have no internal stabilizing members to prevent undesirable distortion of the conveyor housing.

An enclosed conveyor module adapted to be connected with other modules in series, comprising in combination: a unitary tubular housing having a rounded uppeR longitudinal side and a planar longitudinal lower side which lower side is removable for purposes of cleaning out spilled materials; a first pair of longitudinal support members extending respectively along the two lateral edges of said planar longitudinal lower side to reduce deformation of said housing caused by compression; a second pair of longitudinal support members extending longitudinally along opposite lateral sides of the interior of said housing to reduce deformation of said housing; roller means attached to said second pair of longitudinal support members for supporting a conveyor belt; at least one longitudinal support member extending longitudinally along the upper side of said housing to reduce deformation of said housing; at least one transverse beam mounted within said housing and having mutually opposite ends of said beam attached respectively to the interior of said housing side walls so as to reduce deformation of said housing when under stress; and at least one circumferential flange means having opposite ends and encircling said housing so as to reduce deformation of said housing when under stress, said flange means being attached at the respective ends thereof to said first pair of longitudinal support members.
