Abstract: The present invention provides a reciprocating floor conveyor having floor members (10, 10') formed with a side lip (24, 26) overhanging either or both side edges. The slip (24) on one floor member (10) is contiguous with a closely-confronted side (16) or lip (26) of an adjacent floor member (10') when the floor members (10, 10') are installed. The lips (24, 26) form a narrow, material-excluding gap (28) between the floor members (10, 10'). An elongated seal strip (38) having a base portion (40) received in and retained by a longitudinal seal-retaining groove (30) formed in a side (14) of a floor member (10) is provided between each pair of adjacent floor members (10, 10'). A longitudinally straight, vertically convex side surface (36) may be provided vertically above the retaining groove (30) to bias the seal strip (38) into contact with a side surface (48) of an adjacent floor member (10' ).

Abstract: Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1, 2, 3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (128, 130, 132) to which the cylinders (1, 2, 3) are connected. These beams (128, 130, 132) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (128, 130) which depends from an upper central portion of a transverse truss (80, 82). Each longitudinal drive member (128, 130, 132) is welded to a transverse drive beam (10, 12, 14) by fillet welds on each side of the longitudinal drive tube (128, 130, 132). Each such drive tube (128, 130, 132) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22). The guide beams (22) are small in size and are welded on both sides to transverse support beams (24). The construction of the slide bearings (26) permits the use of large dimension, strong, undressed fillet welds. The slide bearings (26) include wing portions (68) on each side which abut similar wing portions (68) on sideways adjacent bearings (26). The floor members (28) are held vertically relative to the bearings (26) by the engagement of bottom flanges (36, 38) within side slots (72) formed in the bearings (26). The floor members (28) add strength and stiffness to the bearings (26) and the abutting contact of the wing portions (68) cause the bearings (26) to mutually brace each other.

Abstract: A single elongated piston rod (12) is secured by a ball and socket joint (62, 66, 68) at one end to a frame member (82). At its opposite end it is restrained against up and down and sideways movement but is not connected. A plurality of piston heads (22, 24, 26) are spaced apart along the length of the piston rod (12). A traveling cylinder (28, 30, 32) is associated with each piston head (22, 24, 26), a transverse drive beam (16, 18, 20) is connected to each traveling cylinder (28, 30, 32). Each transverse drive beam (16, 18, 20) is connected to a separate group ("1", .cent.2", "3") of the floor members (14) which make the reciprocating floor conveyor.

Abstract: A floor member (10, 10', 124) of channel form is pushed downwardly to install it onto bearings (32, 32', 32") which have been previously installed onto guide tubes (14) which extend in the same direction as the floor members (10, 10', 124). The bearings (32, 32', 32") have sidewall portions (60, 62, 108, 110) which slope downwardly and outwardly to a lower edge (64, 66, 138, 140). These sidewalls (60, 62, 108, 110) are connected at their upper portions to the bearings (32, 32', 32") in such a way that they will flex inwardly, into spaces provided for them, in response to the downward "snap on" movement of the floor members (10, 10', 124). Brace wings (48, 50, 130, 132) may be provided to function together with the lower edges (64, 66, 138, 140) to hold the floor members (10, 10', 124) onto the bearings (32, 32', 32"). Bearings (32, 32', 32") themselves snap onto the guide beams (14). These bearings (32, 32', 32") include lock flanges in the form of cantilever springs, resulting in a good tight fit despite size differences which may exist due to low manufacturing tolerences.

Abstract: Piston rods (60, 62) of three linear hydraulic motors (36, 38, 40) are connected at their outer ends (64, 68) to two spaced apart transverse frame members (10, 12). A cylinder housing (72) is driven back and forth along each pair of piston rods (60, 62). Three transverse drive beams (48, 50, 52) are provided. Each drive beam (48, 50, 52) is directly connected to an associated one of the cylinder housings (72). Three sets of floor slat members (1, 2, 3) are provided. Each set (1, 2, 3) is connected to an associated one of the transverse drive beams (48, 50, 52). The linear hydraulic motors (36, 38, 40) are operated for moving the floor slat members (1, 2, 3) in one direction, for advancing a load, and for retracting them in the opposite direction. Each cylinder housing (72) has four fluid chambers (82, 84, 86, 88). The first and third chambers (82, 86) are interconnected and the second and fourth chambers (84, 88) are interconnected. This arrangement provides adequate force producting area with a relatively small diameter cylinder housing (72). Fluid passageways (110, 112) are formed in the piston rods (60, 62). Transfer valves (138, 140) and U-shaped tubes (134, 136, 126, 128) are clamped onto the outer end portions of the piston rods (60, 62) by means of a pair of clamp plates (190, 192, 214, 224) and interconnecting nut and bolt assemblies (194, 226).

The bearings (16, 90, 144) have sidewall portions which slope downwardly and outwardly to a lower edge (76, 108, 154, 156). These sidewalls (66, 68, 100, 102, 150, 152) are connected at their upper portions to the bearings (16, 90, 144) in such a way that they will flex inwardly, into spaces provided for them, in response to the downward "snap on" movement of the floor member (10). Brace wings (52, 54, 110, 112, 174, 176) may be provided to function together with the lower edges (76, 108, 154, 156) to hold the floor members (10) onto the bearings (16, 90, 144). Bearings (90, 144) are provided which themselves snap onto the guide beams (12', 12").

Abstract: A front shield extends across an end portion of a reciprocating floor conveyor above the conveyor slats. Each slat has a front end that rebiprocates longitudinally between first and second positions as the slat reciprocates. A multiplicity of bristles are carried by the shield and depend downwardly therefrom. The lower ends of the bristles contact a top surface of the slats rearwardly of the first and second positions. The bristles are bent by contact with the top surface to preload them into contact and maintain them in contact as the slats reciprocate. This prevents particles of material and debris from passing under the shield. The bristles are mounted on the shield via a carrier that is vertically adjustable relative to the shield to permit adjustment of the preload. The bristles are provided in a plurality of rows positioned one behind another in a longitudinal direction, with each row extending across the conveyor substantially continuously across each slat. The bristles have a sufficiently narrow cross section and are sufficiently close to each other to provide a substantially constant seal across contoured slats.

Abstract: A drive frame assembly includes opposite transverse drive frame members (64), each of which includes a metal plate (66) with a central portion having a plurality of longitudinal corrugations (68). The central portion is stiffened by transverse beams (78, 80).
