An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.

A self-contained seed tender (20) includes a plurality of bins (48) as well as a conveyor system (30) with a lower conveyor (32) and a shiftable lift conveyor (34). The lift conveyor (34) is shiftable between a stowed, travel position astride the bins (48) and a central, rearwardly extending delivery position. A deployment assembly (38) serves to sequentially pivot the lift conveyor (34) about an upright axis, followed by lateral translation thereof to the central use position. The conveyor (34) can then be rotated and elevated as desired for off-loading of seeds. The tender (20) may also be used for delivery of other types of agricultural particulates.

An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.

The present invention is directed to an apparatus for creating a stockpile of bulk material, comprising a conveyor having a feed end and a distribution end; a stabilizer at the feed end of the conveyor; and a support at the distribution end of the conveyor; wherein the support includes a primary hydraulic cylinder having a base portion connected to the support and an end portion which extends and retracts longitudinally to alter the angle between the conveyor and the ground; and a secondary hydraulic cylinder having one end connected to the support and the other end connected to the primary hydraulic cylinder, where the secondary hydraulic cylinder extends and retracts in a lateral direction, thus pivoting the primary hydraulic cylinder against the support. This design is simpler and less expensive than a conveyor with an undercarriage and makes for a smaller staging area as room for the undercarriage is unnecessary.

A side-dump truck containing aggregate material can be driven over a ramp assembly for unloading. Aggregate material from the side-dump truck is deposited laterally to a side conveyor system, which has a first side conveyor and a second side conveyor pivotable from the conveying configuration to a transport configuration. The aggregate material is conveyed by the side conveyor system being in the conveying configuration to an unloading conveyor system, which has a first unloading conveyor at least partially beneath the side conveyor system.
