Abstract: Systems and method for forming a stable silo face in bulk material are disclosed. Particularly, systems and methods for forming a negative rake angle in a silo face of bulk silage are disclosed. Rotation of an articulated arm (e.g., raising and lowering), altering a length of the articulated arm (e.g., extension or retraction), and movement of a machine relative to the silo face (towards and away from) may be automatically controlled to form the negative rake angle. Different implementations contemplate automated control of all or fewer than all of these operations.

Suspended from the boom by a pair of winch activated cables is a scraper. The scraper includes an elongated frame having a proximal end that is rotatably and slidably mounted on the column below the boom. Secured along the length of the frame is one or more rotatable augers.

The conveyor is supported on the transport vehicle by a rigid truss frame arrangement including upper and lower pivot arms having ball joint connection to the conveyor so as to allow rotation of the conveyor substantially about its longitudinal axis in response to changes in ground contour. The conveyor is movable between lowered operating and raised transport positions. Counterbalance springs limit the contact force of the conveyor acting on the ground surface during operation.

Abstract: An endless conveyor belt 10 provided with angled-over entraining cleats 12 as well as lateral corrugated sidewalls 11 serves the purpose of unloading bulk material 1 from a ship 2 in particular, which not only carries the bulk material 1 out of the ship 2 but also picks the same up automatically. The conveyor belt 10 hangs down with both legs 10' and 10" from an upper driving drum 20 within a conveyor framework 3 and runs freely below the conveyor framework 3 in a loop 21 formed merely under the action of the weight of the conveyor belt without application of external tensioning devices. The conveyor framework 3 is lowered so far into the bulk material 1 that the loop 21 shortens in vertical direction and the conveyor belt 10 digs into and picks up the bulk material 1 with the entraining cleats 12. A vertically displaceable delimiting drum 27 in the loop 21 prevents an excessive lateral displacement of the loop 21 as a reaction to the scooping action.

Abstract: A silo or the like for storing pulverulent, granular or lumpy material has a wall which encloses the silo storage space, a roof whose pitch substantially corresponds to the angle of repose of the material, an inlet opening in the silo roof, an outlet opening in the silo floor, and a screw conveyor suspended from a beam rotatable about the axis of the silo. The beam is inclined downwardly from the inlet opening of the silo and extends substantially parallel to the roof pitch, and the conveyor is suspended from the beam by means of wires which are adjustable independently of each other with respect to their length. The conveyor can thus be anchored close and parallel to the supporting beam when material is fed into the silo, and be disposed at a suitable angle, preferably inclined downwardly toward the center of the silo, when material is discharged from the silo.

Abstract: An auger assembly for transporting seed, fertilizer or other particulate material. The assembly provides an auger within a stationary tube; the auger is mounted to allow free axial movement between adjustable limits. In the normal augering position, the auger extends beyond the tube into the particulate material.

Abstract: A raker boom supports a plurality of independently driven and mounted rotatable raker wheels which are applied to the face of a pile of material to dislodge and move the material downwardly toward a bucket wheel and conveyor for gathering and conveying the material to a remote location for processing. The boom is capable of rotating in a vertical plane so that the raker wheels can contact and remove all of the material through the depth of a pile. By operating the raker wheels individually and mounting them independently, the raker apparatus can travel and apply the individual raker wheels over the surface of a pile of material regardless of its contour. The wheels can break up lumps of material, especially on the surface of the pile, and mix the material with other material within the pile. In one configuration of the preferred embodiment, a pair of opposed raker wheel booms are mounted on a raker carriage which itself is mounted for reciprocal travel on a raker truss.

Abstract: An auger flotation limit for a crop harvesting header on which a floating auger is utilized is disclosed wherein a lower stop, defining the lower limit of movement of the auger, is connected to the upper stop, defining the upper limit of auger movement, by a strap mechanism. An adjusting mechanism operatively engages the lower stop for selectively adjusting the positional relationship between the auger and the floor of the header. The strap mechanism interconnecting the upper and lower stops permits the lower stop to be selectively adjusted without effecting the amount of flotational movement permitted to the auger. A fore-and-aft adjustment mechanism is also provided to permit the auger to be selectively adjusted in a fore-and-aft direction relative to the rear wall of the header.

Abstract: An apparatus for unloading bulk material from a storage space includes an upward conveyor (14), in particular a screw conveyor. For scraping the bulk material to the inlet end (22) of the upward conveyor (14), there is a scraper conveyor (27, 28) which is pivotally movable up and down and is telescopically extensible. The scraper conveyor is pivotally connected to a protective tube (24) which is rotatable and extends about the upward conveyor (14). The protective tube is located within a pressure-absorbing pipe which prevents the bulk material from impeding the rotational movement of the protective tube. This arrangement makes it possible for the scraper conveyor to remove bulk material from different regions of the storage space, including corners.

Abstract: The disclosure is directed to a take-up head for a conveyor installation that removes bulk material from the hold of a ship. The take-up head includes a vertical conveying tube carried by a frame, the lower end of the tube defining a take-up aperture. A rotary feeder having a plurality of radially extending spiral veins is rotatably driven to drive material inwardly to the take-up aperture. A holding device, which takes various forms in the several embodiments, projects downward in coaxial relation relative to the feeder to engage the bulk material and resist lateral movement of the take-up head. Anchoring apparatus, which takes the form of a plurality of laterally extending pivotal arms or a laterally extending auxiliary conveyor, is constructed for lowering into engagement with the material to resist rotation of the frame as the feeder rotates. The take-up head is suspended from an on-shore jib that moves the head to various positions within the ship's hold to remove all bulk material.
