Abstract
In a walking floor reciprocating slat conveyor having a plurality of floor beams to support a load, and being longitudinally reciprocal to move the load longitudinally to an unloaded condition, and being supported by a transverse subfloor, having guides to control movement of the floor beams, and bearing/seal devices mounted to the subfloor and in bearing and sealing contact with the floor beams to prevent material that is part of the load supported by the floor beams from migrating below the floor beams.
Claims20
A walking reciprocating floor system for use in moving a load, which includes bulk particulate materials or the like, disposed in a designated area;
- , comprising:
- a plurality of floor beams, said floor beams being adapted for supporting particulate materials thereon, and moving said load to an unloaded position, each said floor beam terminating in opposed vertically disposed side walls, said floor beams being disposed in side by side relation, and each being reciprocal along a longitudinal axis;
- a subfloor, said subfloor comprising a series of support members for supporting said floor beams for reciprocal movement relative thereto;
- guide means for guiding the movement of each said floor beams beam along a predetermined path, each said guide means being secured to one said support members member, each said floor beam further having a pair of depending opposed L shaped L-shaped members, said L shaped L-shaped members being disposed about one of said guide means for controlled directional movement there along when the floor beams reciprocate;
- and
- means defining a bearing/seal, said bearing/seal being mounted to said subfloor, and contacting the vertically disposed sidewalls side walls of said floor beams to provide bearing support therefor, and to thereby serve as a seal against the inadvertent passage of the particulate material disposed on the walking floor beams from its a position on the floor beams to a place there beneath therebeneath.

A walking reciprocating floor system for use in a moving bulk particulate materials or the like, disposed in a designated area;
- , comprising:
- a plurality of floor beams, each of said floor beams having a flat, essentially horizontally disposed upper surface, said floor beams being adapted for supporting and moving particulate material placed thereon, each said floor beam terminating in opposed vertically disposed side walls, said floor beams being disposed in side by side relation, and each being reciprocal along a longitudinal axis;
- a subfloor, said subfloor comprising a series of support members, said support members being disposed transverse to the longitudinal axes of said floor beams, and positioned for supporting said floor beams for reciprocal movement relative thereto;
- guide means for guiding the movement of each said floor beams beam along a predetermined path, each said guide means being secured to one said support members member, each said floor beam further having a pair of depending opposed L shaped L-shaped members, said L shaped L-shaped members being disposed about an associated one of said guide means for controlled directional movement there along when the floor beams reciprocate;
- and
- means defining a bearing/seal, said bearing/seal being mounted to said subfloor on opposite sides of an associated guide means, and contacting the vertically disposed side walls of said floor beams to provide bearing support therefor, and to thereby serve as a seal against the inadvertent passage of particulate material disposed on the walking reciprocating floor conveyor from its position on the floor conveyor to a place there beneath therebeneath.

A reciprocating slat conveyor for conveying a load that includes particulate material, said conveyor comprising:
- a plurality of side-by-side conveyor slats that are movable longitudinally in a first direction, for conveying the load, and are retracted longitudinally in the opposite direction;
- each said conveyor slat having a load engaging upper region including a pair of substantially horizontal, upper side portions, each with a lower surface and a longitudinal edge-forming portion, depending below said lower surface and including a lower edge;
- a base structure including a plurality of longitudinal guide members, one for each said conveyor slat, and a plurality of longitudinal slat support members, one for each pair of adjacent upper side portions of said conveyor slats;
- each said slat support member being positioned below an adjacent pair of said slat upper side portions and including an upwardly directed, hard plastic bearing/seal surface;
- and
- each said lower edge contacting and sliding along a said upwardly directed bearing/seal surface that is below said lower edge,
- wherein by this contacting, each lower edge and the bearing/seal surface below it seals against passage of said particulate material from a region above the conveyor slats to a region below the conveyor slats, and weight of the conveyor slats and the load on the conveyor slats is transmitted downwardly from the conveyor slats onto the slat support members.
