Chain conveyor

A link assembly for a conveyor chain, the link assembly comprising:

• a link including a first portion and a second portion, the second portion oriented parallel to and spaced apart from the first portion, the first portion including a first outer surface facing away from the second portion and a first sprocket-engaging portion protruding from the first outer surface, the second portion including a second outer surface facing away from the first portion;
• and
• a flight positioned adjacent an end of the first sprocket-engaging portion, the flight including a first part made from a first material and a second part made from a second material having a higher hardness than the first material;
• wherein as the first part wears during normal use, the second part protrudes beyond a surface of the first part and provides a scraping edge.

A conveyor chain comprising:

• a first link including a first portion and a second portion, the second portion oriented parallel to and spaced apart from the first portion, the first portion including a first sprocket-engaging portion protruding laterally away from the second portion, the second portion including a second sprocket-engaging portion protruding laterally away from the first portion;
• a second link including a first portion and a second portion, the first portion of the second link including a first sprocket-engaging portion protruding laterally away from the second portion of the second link, the second portion of the second link including a second sprocket-engaging portion protruding laterally away from the first portion of the second link;
• a coupler link including a first end and a second end;
• a first connecting pin extending through the first end of the coupler link, the first connecting pin extending between the first portion of the first link and the second portion of the first link to removably couple the first end of the coupler link to the first link, the first connecting pin oriented parallel to and offset from the first sprocket-engaging portion and the second sprocket-engaging portion of the first link;
• a second connecting pin extending through the second end of the coupler link, the second connecting pin extending between the first portion of the second link and the second portion of the second link to removably couple the second end of the coupler link to the second link, the second connecting pin oriented parallel to and offset from the first sprocket-engaging portion and the second sprocket-engaging portion of the second link;
• and
• a first flight positioned adjacent an end of the first sprocket-engaging portion of the first link, the flight including a first part made from a first material and a second part made from a second material having a higher hardness than the first material.
