Abstract

An improved apparatus for conveying solid particulate material which includes a generally flexible receptacle fixedly situated within a frame. The receptacle has a top, a bottom, at least one wall defining an interior and a longitudinal axis perpendicular with the top and bottom. The improvement comprises a dump structure at the bottom comprising a dump aperture, a first flap, and a second flap. The first flap has a first connection along a first flap width with the wall and with the frame adjacent to the dump aperture, extends a first length from the first connection, and is swingable about the first connection from a first position blocking the dump aperture toward an open position. The second flap has a second connection along a second width with the wall and with the frame adjacent to the dump aperture and is swingable about the second connection from a closed position blocking the dump aperture toward an open position. The dump structure further comprises at least one side flap being connected with the wall adjacent to the dump aperture intermediate the first flap and the second flap. Each side flap has a third connection along a third width with the wall and a fourth connection with the first flap along the first length. A first bias member urges the second flap toward the closed position. Second bias members urge each side flap toward the interior.

Dependent claims

An improved apparatus for conveying a particulate material;

the apparatus including a generally flexible receptacle substantially fixedly situated within a space delimited by a frame;
said receptacle having a top, a bottom, and at least one wall connecting said top with said bottom and defining an interior;
said receptacle being coupled with said frame at a plurality of coupling loci;
said frame having a longitudinal axis substantially perpendicular with said top and with said bottom of said receptacle when said receptacle is substantially fixedly located within said frame;
said receptacle having a fill structure at said top for providing filling access to said interior;
the improvement comprising:
a dump structure at said bottom for providing dumping access to said interior;
said dump structure comprising
a dump aperture;
a first flap;
said first flap having a first articulate connection along a first flap width with said at least one wall and with said frame adjacent said dump aperture;
said first flap extending a first flap length from said first articulate connection and being swingingly positionable about said first articulate connection from a closed position substantially blocking said dump aperture to an open position, a first plane substantially containing said first flap forming an acute angle with said axis when said first flap is in said open position;
a second flap;
said second flap having a second articulate connection along a second flap width with said at least one wall and with said frame adjacent said dump aperture;
said second flap extending a second flap length from said second articulate connection and being swingingly positionable about said second articulate connection from a closed position substantially blocking said dump aperture to an open position, a second plane substantially containing said second flap forming an acute angle with said axis when said second flap is in said open position;
at least one side flap;
each respective side flap of said at least one side flap being articulately connected with said at least one wall substantially adjacent said dump aperture intermediate said first flap and said second flap;
each said respective side flap having a third articulate connection along a third flap width with said at least one wall and a fourth articulate connection with said first flap substantially along said first flap length;
and
a first bias means coupled with said second flap;
said first bias means urging said second flap toward said closed position.

18 more elements

An apparatus for storing and transporting a solid particulate material;

the apparatus comprising:
a frame, said frame including a plurality of frame members arranged to delimit a substantially right polyhedron;
said polyhedron having a top, a bottom, a plurality of sides, an open interior, and a longitudinal axis substantially perpendicular with said top and with said bottom;
and
a repository, said repository being coupled with said frame and substantially fixedly oriented within said open interior;
said repository having a fill aperture in a top end, said fill aperture being accessible through said top of said frame for filling said repository with said material;
said repository having a dump system in a bottom end opposite said top end, said dump system and said bottom of said frame being arranged to facilitate emptying said material from said repository;
said dump system comprising
a dump aperture,
a first flap having a first articulate connection with said repository substantially adjacent said dump aperture and swingingly orientable about said first articulate connection from a closed position substantially blocking said dump aperture to an open position substantially unblocking said dump aperture;
a second flap having a second articulate connection with said repository substantially adjacent said dump aperture and swingingly orientable about said second articulate connection from a closed position substantially blocking said dump aperture to an open position substantially unblocking said dump aperture;
at least one side flap;
each respective side flap of said at least one side flap having a third articulate connection with said repository substantially adjacent said dump aperture intermediate said first articulate connection and said second articulate connection;
each said respective side flap having a fourth articulate connection with said first flap;
and
a first bias means coupled with said second flap;
said first bias means urging said second flap toward said closed position.

14 more elements

An apparatus for storing and transporting a solid particulate material;

the apparatus comprising:
a frame;
said frame having a top and a bottom generally opposite said top, said frame including a support frame and a hatch, said support frame including a plurality of frame members arranged to delimit an interior, said hatch being swingingly coupled with said support frame at said bottom;
and
a repository;
said repository being coupled with said frame and substantially fixedly oriented within said interior;
said repository having a fill aperture at said top, said fill aperture being accessible through said frame for filling said repository with said material;
said repository having a dump system at said bottom;
said dump system being configured to facilitate emptying said material from said repository while said repository remains coupled with said frame;
said dump system comprising a dump aperture coupled with said support frame and coupled with said hatch in a manner facilitating opening said dump aperture when said hatch is in a first position and closing said dump aperture when said hatch is in a second position.
