摘要:
An agitator assembly mountable to the forward side of a circular bin unloading device in relation to pivoting of the device about a vertical central axis of the bin. Agitator bars of the present agitator are powered to rotate to engage and break up clumps of particulate material prior to engagement of the material with auger assemblies of the unloading device. Adjusting brackets mount the agitator assembly to the auger assembly to facilitate elevational adjustment of the agitator relative to the bin floor.
摘要:
A method of discharging particulate material from a hopper which minimizes vibration and impact loading is disclosed. The method provides a centrally located discharge column having a series of discharge openings extending vertically of an annular mass of particulate material in the hopper. The particulate material is discharged from a generally conically shaped, downwardly and inwardly directed, top portion of said mass of particulate material, progressively downwardly, through a choked flow discharge path provided by the interior of the discharge column.

A transmission couples the main drive of an electrostatographic development system to a toner dispensing roll and a spring-loaded striker of a toner dispenser for the development system. The transmission typically includes a Geneva wheel for periodically actuating a lever arm which is coupled by a one-way clutch to a drive shaft for the toner dispenser. That drive shaft suitably is, in turn, mated with a slot at the outer end of the dispensing roll by an enlarged flat or key which functions to alternately cock and release the striker as the dispensing roll is being rotated.
摘要:
This invention relates to a storing and dispensing device for powdered or granular material, such as fertilizer for example, having provision for part or all of the following capabilities:1. The jarring loose of caked or adhering material within the dispenser;2. The dispensing of the material intermittently in chosen predetermined small quantities;3. The dispensing of the material continuously at a chosen rate; and4. The dispensing of the material with the dispensing end of the device pointed up or down.
摘要:
An apparatus for minimizing arching of granular material within a gravity operated, batch-type hopper. A plate rotatable about a horizontal shaft is mounted within the hopper above a bottom discharge opening. Prior to charging the plate is rotated to a horizontally extending position and during discharging to a vertically extending position.

The invention consists of a feeder valve for periodically discharging material from a storage hopper or other source and consists of a valve housing having a valve aperture passing therethrough and valve opening and closing means consisting of a plurality of vanes or blades extending across said valve aperture and being rotatable about their axes from a horizontal position, in which they close said aperture and a vertical position in which they open said aperture.
摘要:
A rotary feeder has a valvular rotor rotating on an axis in a cylindrical cavity. A plurality of rigid, free-floating blades project from a hub of the rotor to delimit several material-receiving pockets circumferentially distributed over the hub. The inner edges of the blades rest in axial recesses in the hub and are supported by fixed projections extending outwardly from the hub along the trailing side of the blades. The recesses permit limited angular movement of the blades relative to the hub. The blades have widths from the hub to the periphery of the cylindrical cavity greater than corresponding radii through the inner edges of the blades at the hub, whereby the blades are angularly inclined relative to such radii. Top portions of the blades are applied to peripheral wall portions of the cylindrical cavity. The recesses, the fixed projections, and peripheral wall portions of the cylindrical cavity cooperate to hold the blades in position. The fixed projections carry means for urging the blades toward the corresponding radii. The blades are biased or periodically adjusted angularly toward the mentioned corresponding radii during wear of the outer portions and the peripheral wall portions to maintain worn top portions of the blades applied to the peripheral wall portions of the cylindrical cavity.
