Abstract:
A plow (P) sits down on movable slats (10) of a reciprocating slat conveyor formed of the movable slats (10) and fixed slats (12) which are between the movable slats (10). The movable slats (10) and fixed slats (12) define valley regions between the movable slats (10). The plow (P) has fingers (92, 106) which extend into the valley regions. During the unloading operations, the plow (P) is moved rearwardly by the moveable slats (10), together with the load (L) that is on the conveyor. When the plow (P) reaches the rear end of the conveyor, it tips rearwardly and discharges the remaining portions of the load (L) off from the conveyor. Then, a teather (T) is wound onto a winch and used for pulling the plow (P) forwardly back into a forward parked position (FIG. 15).
Abstract:
Fixed conveyor slats (12) in the nature of beams extend over a window in support framework (53, 100, 102, 116, 118) for the movable and fixed slats (10, 12) in a reciprocating slat conveyor. The fixed slats (12) support the movable slats (20), including in the region of the window. The movable slats (10) are in the nature of box beams, providing them with strength and stiffness in the region of the window. At the rear end of the conveyor, the movable slats (10) move onto support brackets (120) which prevent the rear end portions of the slats (10) from being damaged when they are in a position overhanging a rear wall (84) and material is dropped from above down onto the rear end portions of the slats (10).
Abstract:
A plurality of hold-down bearings (12) are locked into position on longitudinal guide beams (12, 12′). Anti-splash bearings (10) are positioned on the guide beams (12, 12′) longitudinally between the hold-down bearings (12). The anti-splash bearings have bottom flaps (46, 48) which contact bottom flanges (36, 38) on the floor slats (20) and block the upward flow of water into the region below the conveyor slats (20). The hold-down bearings (20) also block to a considerable extent the upward movement of water into the underneath regions of the conveyor slats (20).
Abstract:
Conveyor slat bottom flanges (78, 80) are positioned vertically between side portions of upper and lower clamp members (52, 54). The upper clamp member (52) is within the conveyor slat (70) and its side portions are above the conveyor slat flanges (78, 80). The lower clamp member (54) is welded or otherwise secured to a transverse drive beam (56). Its side portions are below the conveyor slat bottom flanges (78, 80). Bolts (164) project upwardly through openings in the transverse drive beam (56) and the lower clamp member (54) and thread into threaded openings (160) in the upper clamp member (52). Or, bolts (170) extend downwardly from the upper clamp part (52) through openings in the lower clamp part (54) and openings in the drive beam (56), to nuts (170) that are below the drive beam (56). Tightening of the bolts (170) causes the conveyor slat bottom flanges (78, 80) to be clamped between the two clamp members (52, 54). This secures the conveyor slats (70) to the transverse drive beam (56) without the need of forming fastener holes in the top (72) of the conveyor slat (70).
Abstract:
Side-by-side conveyor slats (62) have laterally outwardly extending opposite upper side portions (72,74), each including a depending, longitudinal support and seal bead (B) having a lower edge that contacts and slides along a longitudinal bearing/seal surface (78) on a longitudinal support beam (14) that is below it. The conveyor slats (62) have laterally spaced apart depending leg portions (24,26), each with a laterally outwardly directed flange (64,66). These flanges (64,66) are offset vertically below the upper side portion (72,74) on its side of the conveyor slat (62). A longitudinal support beam (14) is positioned between each adjoining pair of conveyor slats (62), below adjacent upper side portions (72,74) of the adjoining conveyor slats (62). A longitudinal bearing/seal member (80) is supported on, extends along and is connected to each support beam (14). The longitudinal bearing/seal members (80) have side portions that project laterally outwardly from opposite sides of the support beams (14), each into a position that is above an adjacent outwardly directed flange (64,66) on an adjacent depending leg (68,70) of an adjoining conveyor slat (62), for blocking upward movement of the conveyor slats (62) up off of the bearing/seal members (80).
Abstract:
Alternate conveyor slats have laterally outwardly projecting, upper side portions, each with a depending, longitudinal, load transmitting bead (B). The beads (B) sit down on and slide longitudinally along bearing/seal surfaces (90a, 92a) that are a part of upper side portions of the intermediate conveyor slats (12). The alternate conveyor slats (10) are guided by longitudinal guide beams (14). Hold down members (20) secured to the guide beams (14) serve to resist unwanted upward movement of the conveyor slats (10). The intermediate conveyor slats (10) are snap-fitted onto bearings (18) which in turn are snap-fitted onto longitudinal guide and support beams (19). The weight of conveyor slats (10), and the weight of any load on the conveyor slats (10), is transmitted by the contact of the bead (B) with the bearing/seal surfaces (90, 92) to the conveyor slats (12). This weight, the weight of the conveyor slats (12), and the weight of any load on conveyor slats (12), is transmitted to the bearings (18) and from the bearings (18) to the guide and support beams (16).
Abstract:
A garbage handling system (10) including a plurality of garbage collector bins (12) each provided with a reciprocating floor conveyor (50) and a movable, suspended chain assembly (30) at an outlet end (16) of a garbage collector bin for the purpose of breaking up accumulated garbage as the garbage is transferred out of the collector bin to a subsequent processing station, such as an incinerator. The size of each collector bin is large enough to hold several loads of garbage. The chain assembly is movable up and down, as well as laterally, to assist in breaking up garbage that has bound together while in the collector bin. The sidewalls (36) of collector bins (12) are angled inwardly to prevent garbage from becoming lodged between the sidewalls, preventing the reciprocating floor conveyor from moving the garbage.
Abstract:
A trailer (T) and a dock (D) are provided with substantially identical slat conveyors (10, 12). Each conveyor (10, 12) has alternating conveyor slats (36, 36′) and lifting/holding slats (38, 38′). The trailer (T) is backed up to the dock (D). Upper portions of the lifting/holding slats (38, 38′) are coupled together at their ends. The confronting ends of the conveying slats (36, 36′) are also coupled together. A mechanism carried by the dock (D) raises and lowers the upper portions of the two sets of lifting/holding slats (38, 38′) a drive mechanism carried by the dock (D) where it reciprocates both sets of conveying slats (36, 36′).
Abstract:
An elongated plastic slide bearing (10) comprises a top (30), sidewalls (32, 34) depending from the top (30), and connecting to walls (36, 44, 48 and 38, 46, 50) that form laterally inwardly extending recesses (40, 42). Lock ribs (62, 64) extend upwardly and inwardly from the inner walls (44, 46) of the recesses (40, 42) to upper edges (66, 68). The upper edges (66, 68) are spaced below the bearing top (30). The bearing (10) is adapted to be set down onto a support beam (14) that includes laterally outwardly projecting lock flanges (22, 24) at its top. The lock ribs (62, 64) contact the lock flanges (22, 24). When the bearing (10) is pushed downwardly, the lock ribs (62, 64) bend outwardly and allow the lock ribs (62, 64) to move into a position below the lock flanges (22, 24). When that happens, the lock ribs (62, 64) assume substantially unstressed positions in which their upper edges (66, 68) are below the lock flanges (22, 24). The sidewalls (32, 34) and the lock ribs (62, 64) are bendable to allow a floor slat (12) to be snap-fit down onto the bearing (10).
Abstract:
A screw (114) is rotated to move a head (110, 110′) against a first squeeze bar (30) and through a threaded opening (114) in a second squeeze bar (32), for moving the squeeze bars (30, 32) relatively together. This movement rotates cam bars (100, 102, 104, 106) in position, causing them to move a lower spread bar (24) away from an upper spread bar (22). This pulls downwardly on a bolt (16) which is connected to the lower spread bar (24). As the bolt (16) moves downwardly, its head (18) pushes downwardly on an upper clamp member (52′), moving it towards a lower clamp member (54″). This firmly clamps bottom flanges (78, 80) on a conveyor slat (70) between the upper and lower clamps member (52″, 54″), firmly securing the slat (70) to a transverse drive beam (56′).
