1. An industrial metering apparatus, comprising:
a hopper including a housing to contain a bulk material within an inside of the housing, the housing having an upper section including four sides defining a rectangular cross-sectional configuration, and a lower section including at least one wall tapering to an opposite wall so as to reduce the cross-sectional configuration to a bottom, the upper section defining a fill cavity, and a grate extending across the housing to divide the upper section from the lower section, the upper and lower sections being integrally formed together across the four sides, with at least two of the four sides in the upper section having a window opening extending therethrough, each window opening extending from an upper end of the upper section to the grate;
a metering mechanism, coupled to the hopper, to meter a volumetric quantity of the bulk material leaving the hopper, the metering mechanism positioned at the bottom of the lower section;
a discharge opening, coupled to an outlet of the metering mechanism, structurally configured to allow a discharge of the metered quantity of the bulk material;
a window positioned to cover each window opening, each window comprising a transparent panel and a window frame extending therearound, each window frame corresponding to one of the window openings so as to cover each window opening through the side of the housing;
a hinge associated with each window to couple the window frame to the housing, the hinge extending continuously from a top of a first side of the window frame to a bottom of a first side of the window frame, such that the hinge allows the window to hingedly open to allow access to the opening through the side of the housing and hingedly close to prevent the bulk material from escaping from the hopper through the opening; and
a locking assembly associated with each window, the locking assembly comprising a pair of spaced apart handle/post locking mechanisms, each locking mechanism including a handle that actuates a padded post to press against the frame of the window in a closed position, with a seal extending around the window frame to seal the opening in substantially fluid tight engagement when the window is positioned in the closed position;
wherein a lid is disposed on a top opening of the housing of the hopper, the lid structurally configured to seal the top opening in substantially fluid tight engagement; and
wherein the industrial metering apparatus further comprises a coupler to couple the industrial metering apparatus to an excavator.
