  • Patent number: 10059527
    Abstract: A reciprocating slat conveyor, as described herein, includes a floor pan (having a bottom and sidewalls) for at least substantially lining the storage container. The reciprocating conveyor also includes a plurality of slat and beam assemblies (that may be bearinged or bearingless) laterally spaced and substantially parallel to each other on the bottom of the floor pan. Slat and beam assemblies may be positioned on the sidewalls. The floor pan may have an at least generally planar bottom or an at least generally arcuate bottom.

  • Patent number: 9897113
    Abstract: A switching valve module which is part of a switching valve control system for use with reciprocating slat-type conveyors is disclosed herein. Disclosed herein is a switching valve module that includes an inner control valve and an outer control valve. A spool is positioned within the inner control valve and a spool positioned within the outer control valve. Movement of each the spool creates both a spool-type seal and a poppet-type seal between the spool and the respective control valve.

  • Patent number: 9452889
    Abstract: A tipper retrofit bearingless reciprocating slat-type conveyor assembly 200 for use in a load-holding compartment including a plurality of elongate hold down strips 220, a plurality of elongate guide trough subdecks 230, and a plurality of longitudinal slats 210 adjacent to and parallel to each other is described herein. Also described herein is a snap together bearingless reciprocating slat conveyor for use in a load-holding compartment (that has at least one cross-member having an overhang) that includes at least one reciprocating slat-type conveyor assembly 300, 400 and at least one elongate slat 310, 410 at least partially supported by at least one subdeck 330, 430.

  • Patent number: 8887896
    Abstract: A liquid-tight reciprocating floor construction or system includes a plurality of longitudinal sub-deck sections having at least one longitudinal guide beam and at least one longitudinal valley. A first longitudinal side edge of one longitudinal sub-deck section is preferably in a mating relationship with an adjacent second longitudinal side edge of another longitudinal sub-deck section. An internal sealing structure is preferably positioned between adjacent first and second longitudinal side edges to form a longitudinal liquid-tight sub-deck joint therebetween.

  • Patent number: 8616365
    Abstract: A reciprocating slat conveyor includes a plurality of laterally and substantially parallel longitudinal trough-like subdecks and a plurality of longitudinal slats adjacent to and parallel to each other. The slats are in a sliding relationship with a pair of adjacent subdecks and cover the longitudinal space between the pair of adjacent subdecks. The subdecks longitudinally support two adjacent slats at or near a slat longitudinal side edge. The subdecks conduct the movement of the slats, preferably without distinct bearing elements therebetween. Some preferred embodiments include raised double-seal system.
