ABSTRACT:
A large capacity en masse conveyor for bulk materials includes a centrally positioned link type conveyor chain (26) with transverse flights (71) connected to the underside of the chain links (61) at regular intervals. The flights (71) include a main V-shaped angle member (72) with wear shoes (91, 92), which may be replaceable shoes (172), at its outer ends engageable with longitudinal wear strips (93, 94) adjacent the side walls (41, 42) of the conveyor casing (11). An idler roller (29) is upwardly removable from its support (111) upon removal of the cover (49) and fastening bolts (126) and nuts (127). The roller support (111) is upwardly removable from the casing (11) upon removal of the cover (49) and bolts (132) and nuts (131) by which the support (111) is releasably secured to the casing side walls (41, 42). The roller (29) is positioned sufficiently close to the cover (49) so the flights (71) will engage the cover (49) to prevent the chain from jumping the flanges (136, 137) of the roller (29) should the chain (26) be subjected to undulations of predetermined magnitude.
