Abstract: A reclaimer for moving grains and other bulk material in a desired direction includes a substantially cylindrical column upstanding within a storage silo. A track, mounted on the storage silo above the floor, concentrically encircles the column. A motorized carriage is mounted on the track so as to selectively move thereon. Extending between the top end of the column and the carriage is a boom. The proximal end of the boom is rotatably mounted to the column such that movement of the carriage on the tack results in the boom rotating around the column. 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.

Abstract: This invention relates to a top loading, top unloading bottom discharge, ring drive silo unloader that is adapted for use with a hexapod suspension. The unloader features a stationary support frame with an open center concept. The support frame includes three main support members joined together to form a triangular frame. Three bracing members are added to the support frame to form an interior perimeter with a generally hexagon shape that delineates the open central area. A rotating drive ring is suspended from the support frame. An electric motor drives a chain loop that engages the exterior surface of the drive ring and causes it to rotate. A gathering mechanism that includes a subframe with a telescoping tubular support is suspended from the rotating drive ring. An auger is suspended from the tubular support.

Abstract: A device for the emptying of the residual product stored in a silo comprises a series of beams, for example, two or three beams. The first beam is mounted pivotably at a first end thereof on a pivot situated at the center of the discharge opening of the silo. Toward its second end, the first beam is articulated via a pivot to a first end of the second beam. If three beams are provided, the second end of the second beam is similarly articulated via a pivot to the first end of the third beam. Each beam supports a rotatable endless screw for feeding the product in the direction of the first end that beam and thus toward the discharge opening of the silo, and bears against the base of the silo via a drivable wheel which enables the beam to be pivotally displaced over the base of the silo. Each beam also carries a motor assembly for driving the endless screw and the wheel associated with that beam.

Abstract: A silo unloader having a framework and concentric oppositely driven rings with oppositely acting plows to shift particulate material in a silo to a central discharge defined by vertically spaced plates. The rings are driven by compressible rollers such as pneumatic tires, compressed between rings and powered by electric motors. Additional compressible friction rollers engage the wall of the silo in a vertical rolling action to guide vertical movement of the unloader and resist rotational movement of the framework which is suspended on cables.

Abstract: A circular storage container (1) for granular materials is provided with a central support column (4) for a top-loading filling device (9) and a lateral conveyor (20) for pivotal movement around the support column (4). The lateral conveyor (20) is connected to the filling device via a telescopic, vertically extendable feed pipe (12). The support column (4) is constructed either of ring plates (5) or a helically coiled band, both of which have a downward slanting, angular outer edge section (34). The granule material dropped in the vicinity of the support column (4) slides onto the ring plates (5) or along the helically coiled band according to the shape of its alluvial cone, but cannot drop into the discharge shaft. During the removal process the granular material is forced between the ring plates (5) or between the coils of the helically coiled band, from where it drops into the discharge shaft (7).

Abstract: An apparatus for emptying silos enables a telescopically retractable vertical empyting pipe to retract downwardly with an overhead material gathering conveyor in continuous controlled motion without undesirable sudden retraction of individual telescopic components. The lower portions of the telescopic pipe are rotatable about their longitudinal axis to reduce frictional contact between the telescopic members and the stored material, and gradually slide downwardly as the overhead material gathering device is lowered in the silo.

Abstract: In the device according to the invention for emptying bulk material from silos (1), a telescopic fall pipe (24) is used as a delivery shaft for the bulk material to be emptied, which telescopic fall pipe (24) has at least one sliding pipe (27) which is arranged between an upper coupling pipe (25), arranged with the clearing device (4) which can be lifted, and a lower stand pipe (30) or bellows. In order to prevent the sliding pipe (27) from falling down or suddenly slipping through, a fall-prevention feature in the form of a retaining or automatic-retraction device or the like is allocated to the sliding pipe (27), which retaining or automatic-retraction device preferably consists of hydraulic lifting cylinders (36) which control the lifting movements of the sliding pipe. The telescopic fall pipe (24) expediently has only a few pipe sections, preferably only a single sliding pipe (27).

Abstract: The invention relates to an apparatus for supplying a silo with bulk material and for discharging the bulk material from the silo, using a clearing unit which can be raised and lowered in the silo, and which at the same time is mounted pivotably about the silo axis. In the silo a draw-off shaft is in the form of a telescopic gravity-descent tube, via which the bulk material removed by the clearing unit is conveyed out of the silo.In this invention the clearing unit is connected via a bearing to a bridge girder which extends transversely across through the silo and which at its ends is guided in vertical guides on the silo wall. The operating forces are transmitted to the silo wall via the bridge girder.

Abstract: A discharge installation to be used in a silo for bulk material in powdered or granular condition comprising a central column of interspaced annular collar plates surrounding a central discharge chute, subsequent collar plates merging into each other forming a mainly helical path, a traveling scraper device being provided in the space between subsequent collar plates.

Abstract: A force method of and assembly for trickling rock material from a silo. The bottom part of a silo is provided with a vaulting element and a pressure force is generated in a vaulting chamber or closed space below the vaulting element. For optimum trickling action, the forces facilitating trickling are concentrated on a vertical that extends through a trickling or draining outlet by mounting an upright friction plate for eliminating a frictional force and by directing a pressure force and a thermal force or power, which adds to the pressure force, on the same vertical through the trickling outlet along which the linear motion of a point of material occurs.

Abstract: Silo for storing solidify loose material, especially flue ash, which has a conveyor which can be moved on the surface of the stored material and which feeds the material loosened there to a conveyor device located in the silo which brings it to an exit opening provided on the silo floor. This conveyor device is simply and effectively constructed in accordance with the invention by forming it by a falling series of aeration devices on an essentially vertical silo wall. This silo wall is advantageously the circumference of a column provided in the center of the silo. In a first embodiment the mechanically separated and pneumatically loosened material passes through slideless openings into the inner space in the column, from which it is removed at the bottom. In a second embodiment the aeration devices are arranged on the circumference of the column in such a compact series that they result in the formation of an emptying column which follows the column surface and is filled by material fluidized by aeration.

Abstract: This invention relates to the draining of bulk materials which are not spontaneously flowable, from a high-rise silo in which the bulk material is fed from the top layer of the bulk material at any instant, into a central gravity shaft having a bottom extraction facility. To this end, the invention consists in a gravity shaft which is combined with the gastight high-rise silo and is rigid, stationary, tubular and closable at the bottom. The shaft is provided with perforations distributed along its height and circumference, of which at least one is situated at each vertical position of the prevailing level of bulk material. The bottom of the shaft can be sealed off with a slider or a plug of the material which is permitted to be built up to a predetermined height.

Abstract: A high-rise silo in which silage is fed radially by means of revolving feed members to a central vertical clearing shaft of the silo. The silage is withdrawn from the shaft at the bottom. The shaft itself is assembled from separate cylindrical pipe lengths each of which has an internal encircling groove with a sealing ring at the upper end, into which engages an internal co-axial annular flange situated at the lower end of the superjacent cylindrical pipe length, in sealing manner.

Abstract: A silo unloader is of the type having a tripod with inwardly and upwardly inclined legs, including a main leg and lateral legs, surmounting the wall of a cylindrical silo, and a silo unloader mechanism has three generally radially extending horizontal support arms to each of which is secured a suspension cable trained over a sheave at the upper end of one of the tripod legs to suspend the mechanism in the silo. Each of the sheaves is journalled in a yoke which is freely suspended at the upper end of a tripod leg, and because of the way the suspension cables must run from the winch to the sheaves, the yokes are displaced from a vertical suspension by the load on the cables. The structure of the support arms permits securement thereto of the three suspension cables at points which compensate for the displacement of the sheave yokes, so as to cause each cable to hang effectively vertically from the sheave over which it is trained.
