Enclosed belt conveyor assembly

An enclosed belt conveyor assembly for conveying material along a forward longitudinal path of travel, comprising:

• a head section having a head pulley for rotation about a horizontal lateral axis;
• a tail section having a tail pulley for rotation about a horizontal lateral axis;
• one of said tail pulley and said head pulley being a drive pulley with the other of said tail pulley and said head pulley being an idler pulley;
• at least one intermediate conveyor section assembled between said head section and said tail section;
• said intermediate conveyor section including a bottom wall having inner and outer surfaces;
• an endless flexible conveyor belt trained longitudinally over said head pulley and said tail pulley and extending through said intermediate conveyor section defining an upper forward run from said tail pulley to said head pulley, and a lower return run from said head pulley to said tail pulley;
• at least one conveyor belt idler roller in said intermediate section for rotation about a horizontal lateral axis for carrying a portion of said forward run of said conveyor belt;
• said tail section including a tail pulley shroud substantially enclosing said tail pulley and the rear portion of the conveyor belt return run;
• at least one wiper element provided on said conveyor belt which is carried by said conveyor belt in a close relationship with respect to said inner surface of said bottom wall of said intermediate conveyor section for pulling material, that has spilled onto said inner surface of said bottom wall, towards said tail section;
• said tail pulley shroud has an inner surface which is closely positioned to said conveyor belt as said conveyor belt passes around said tail pulley so that as said wiper element passes through said tail section, said wiper will cause at least some of the spilled material being pulled thereby to be directed to the rearward end of said forward run for conveying to the desired discharge location;
• and a material deflector in said tail section which deflects spilled material being carried by the upper surface of said lower return run, laterally towards the sides of said tail section.
