Each of the sections includes a guide plank having a reinforcing plate portion adjacent a respective end thereof and a pin extending outwardly from the reinforcing section. A common connecting plate interconnects the separate sections and it has spaced apart eye openings therethrough into which a respective pin segment extends. The plates have a web between adjacent pins of adjacent sections and the eye openings and the segments are spaced to provide the clearance therebetween. Each guide plank comprises an auger thread plank for coal which is made of a box-like section construction. Each box-like section has an exterior wall covering the pin segments and an inner wall spaced from the exterior wall forming a locking pocket therewith, which receives the locking or connecting plate. The locking or connecting plate has an exterior surface which is flush with the exterior surface of the exterior wall and forms a tread bridge between adjacent sections.
A conveyor chute for chain scraper conveyors, comprising, a plurality of chute sections joined together with a clearance therebetween for free motion of one section in respect to the other, each section including a guide plank having a reinforcing plate portion adjacent an end thereof with an outstanding pin segment, a connecting plate interconnecting said segments having spaced apart eye openings therethrough into which a respective pin segment extends and with a web portion disposed between said pin segments, said eye openings and said pin segments being spaced apart by an amount to provide a clearance of motion between said sections, each of said sections comprising an auger tread plank of a box section configuration having an exterior wall covering said pin segments, an interior wall spaced from said exterior wall and said pin segments, said interior wall forming with said exterior wall a locking pocket adjacent the respective plank ends into which said connecting plate is located, said connecting plate having an exterior surface flush with the exterior surface of said exterior wall to form a tread bridge between adjacent sections.
