Scraper-chain conveyor channel section

A scraper-chain conveyor comprising:

• (a) a plurality of channel sections joined together end-to-end,
• (b) each channel section comprises a lower, trough-shaped part and an upper, trough-shaped part detachably connected to the lower part,
• (c) the lower part includes a pair of side walls fixedly connected together and a plough guide section,
• (d) connectors articulatedly join the juxtaposed side walls of each pair of adjacent channel sections,
• (e) each connector is housed in correspondingly shaped pockets formed in the adjacent portions of the respective side walls of the respective lower parts of the adjacent channel sections,
• (f) said pockets open toward the inside of the channel sections.

A scraper-chain conveyor channel section comprising:

• (a) a lower, trough-shaped part and an upper, trough-shaped part detachably connected to the lower part,
• (b) the lower part including a plough guide section and a pair of side walls having upper edges,
• (c) the upper part including a pair of side walls fixedly connected to a floor plate,
• (d) the side walls of the upper part having upper, free ends with outwardly-extending flanges which rest on the upper edges of the side walls of the lower part,
• (e) co-operable members are associated with the outwardly-extending flanges of the upper part and with the side walls of the lower part and detachably connect the upper part to the lower part,
• (f) pockets formed in the side walls of the lower part open toward the inside of the channel section and house said co-operable members, and
• (g) the side walls of the upper part cover said pockets when the upper part is connected to the lower part.

A scraper-chain conveyor channel section comprising:

• (a) a lower, trough-shaped part and an upper, trough-shaped part detachably connected to the lower part,
• (b) the lower part including a pair of side walls fixedly connected to a base plate, and
• (c) a plough guide section including an extension of said base plate which extends outwardly beyond one of said side walls,
• (d) said plough guide section including a guide member fixedly attached to the lower part and located above said base plate extension.
