Abstract:
A portable telescoping radial stacking belt conveyor for stockpiling bulk particulate material comprising:a. an undercarriage comprised of; i. an axle assembly comprised of; ii. an elongated frame, iii. at least one transport wheel at each end of the frame, iv. at least one radial travel wheel at each end of the frame, v. means for selectively bringing transport wheels and radial travel wheels into contact with the ground, vi. a link attachment point at each end of the frame, vii. attachment point at each end of the frame for attaching one end of an elongated elevating strut, viii. an elongated trailing link having a first end and a second end, the first end pivotably attached to the frame link attachment point, and the second end pivotably attached to, b. a primary conveyor portion having a rectangular cross-section that is open in the center comprising; i. a top chord, a bottom chord, a first truss lattice side and a second truss lattice side, ii. bottom cross members that interconnect the first truss side and the second truss side, iii. a belt supported by iv. troughing roller set assemblies and idler roller set assemblies that interconnect the first and second truss lattice side top chords, v. bottom cross members that interconnect the first and second truss lattice bottom chords, vi. a hitch for hitching the conveyor to a tow vehicle, vii. an infeed hopper, viii. a belt drive motor assembly, c. a secondary conveyor surroundingly receivable by the primary conveyor comprised of; i. a top chord, a bottom chord, a first truss lattice side and a second truss lattice side, ii. bottom cross members that interconnect the first truss side and the second truss side, iii. a belt supported by iv. troughing roller set assemblies and return idler roller set assemblies that interconnect the first and second truss lattice side top chords, v. bottom cross members that interconnect the first and second truss lattice bottom chords, vi. a belt drive motor assembly, d. a winch with a rope linking the primary conveyor and secondary conveyor to positively extend the secondary conveyor from the primary conveyor and to positively retract the secondary conveyor within the primary conveyor, e. a tandem roller walking beam primary truss roller assembly situated at each side of the primary conveyor and proximate the bottom of the discharge end of the primary conveyor, each of the primary truss roller assemblies being engageable with the bottom of the stinger bottom truss chord, f. a tandem roller walking beam secondary truss roller assembly situated at each side of the primary conveyor and spaced apart axially from each primary truss roller assembly, each secondary truss roller assembly being engageable with the top of the stinger bottom truss chord.
