  • Metering device and associated unloading methods for hopper-bottomed storage bins
    Patent number: 10948325
    Abstract: A metering device for metered dispensing of granular material from a hopper bottom storage bin. The device features a metering housing having a housing inlet for receiving said granular material from a hopper outlet of the storage bin, and a housing outlet from which the granular material is dispensable from the housing. A metering mechanism driven by an onboard motor is operable within the housing to dispense the granular material through the housing outlet in a metered fashion. A mounting arrangement is attachable to the storage bin in a position suspending the metering housing below the hopper outlet. The housing is movable into and out of a working position aligned under the hopper outlet, and can also be adjusted in tilt angle to achieve a properly leveled alignment in the working position.
