Abstract:
A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.

Claim (Index 1):
A mobile backfill system for collecting material, comprising:\n a collection tank comprising a body having\n a closed end, \n an open end opposite the closed end and having a generally circular periphery, \n a central, generally cylindrical section extending between the closed end and the open end, and \n a door pivotably connected to the generally cylindrical section so that the door is pivotable about a first axis between a first position, at which the door is spaced from the open end of the generally cylindrical section, and a second position, at which the door seats against the generally circular periphery of the open end, thereby closing the open end, the door having\n a dome-shaped panel, \n a generally circular periphery of the dome-shaped panel that seats against the generally circular periphery of the open end when the door is in the second position, and \n an elongated cross bar rigidly connected to the dome-shaped panel and extending across the dome-shaped panel parallel to the first axis; \n \n a vacuum pump connected to the collection tank that draws an air stream through the collection tank for carrying material into the collection tank; and two over center linkages, each over center linkage extending between a respective first pivotal connection between the over center linkage and the door and a respective second pivotal connection between the over center linkage and the collection tank body so that each over center linkage is movable, when the door is at the second position, over center to a state at which the over center linkage biases the door into the second position, wherein the two over center linkages are connected to the door at respective positions on the door so that force applied to the door by the two over center linkages when the door is in the second position is received by the cross bar.
