Vehicle delivery box system and method

A delivery box system comprising:

• a delivery box having a bottom wall and a sidewall defining a storage area for storing a commodity material,
• a first metering aperture disposed on the sidewall of the delivery box;
• a second metering aperture disposed on the sidewall of the delivery box;
• a first angled plate positioned adjacent the first metering aperture and extending away from the delivery box at a first angle;
• a second angled plate positioned adjacent a bottom portion of the second metering aperture and extending away from the delivery box at a second angle;
• a first expulsion mechanism comprising a first distribution member a first central support joined to the first distribution member, the first expulsion mechanism positioned adjacent the first metering aperture and a portion of the first distribution member extending through the first metering aperture above the first angled plate;
• and
• a second expulsion mechanism comprising a second distribution member and a second central support joined to the second distribution member, the second expulsion mechanism positioned adjacent the second metering aperture and a portion of the second distribution member extending through the second metering aperture above the second angled plate;
• wherein the first expulsion mechanism and the second expulsion mechanism are each configured to rotate about a vertical axis or an axis that is perpendicular to the bottom wall of the delivery box, such that in response to rotation of the first distribution member and the second distribution member, the commodity material is dispensed through the first metering aperture and the second metering aperture.

A method of operating a delivery box system, the method comprising:

• opening a door of a metering aperture of a delivery box to a desired position;
• rotating an expulsion mechanism thereby ejecting at least a portion of a commodity stored within the delivery box through the metering aperture;
• and
• closing the door associated with the metering aperture,
• wherein the expulsion mechanism includes a distribution member configured to rotate around an axis perpendicular to a floor of the delivery box to dispense the commodity,
• wherein a portion of the distribution member extends through the metering aperture during operation of the delivery box system.
