Vertical bulk-conveying apparatus and bulk delivering system utilizing the characteristics thereof

Claim 2

A vertical bulk cargo delivering system comprising: a vertical bulk-delivering unit (71) including a vertical bulk-conveying apparatus comprised of an integral combination of a vertical conveyor (2) and a highspeed bulk projector (5), and a rotary bucket wheel type bulk feeder (6) arranged on one side of said bulk projector, said bulk projector (5) including a bulk receiving chute (53) having bulk inlet mouth (530) opening toward the bulk charging port (63) of said bulk feeder, said vertical conveyor (2) being arranged in a substantially vertical space defined in a tubular casing frame and including two endless conveyor belts (2a, 2b) adapted to be driven upwardly in a substantially vertical direction in a face-to-face overlapping relation closely engaging each other along the opposite side edges thereof so as to serve the purpose of conveying bulk material as held between the opposing faces of the two conveyor belts vertically upward, said two conveyor belts being guided at the bulk-receiving bottom end so as to turn around in directions opposite to each other, said tubular casing frame including a vertical frame section and a lower frame section tiltably jointed thereto and being formed at the bottom end with an overhanging portion, said bulk projector (5) being carried on said overhanging portion of said tubular casing frame to serve to project bulk material rapidly under the effect of centrifugal force in an inclined upward direction to the bottom belt junction where the two endless conveyor belts come to join each other; a rotary boom type unloader (8) arranged for movement along a cargo handling place and including a luffing boom (82); and a unit support frame (79) mounted on said luffing boom at the free end thereof so as to be held at all times in a horizontal position and supporting said delivering unit (71) for vertical movement and rotation about the vertical axis thereof.

Claim 3

A vertical yard delivering system comprising: a delivering unit (71) in the form of a vertical bulk-delivering unit (71) including a vertical bulk-conveying apparatus comprised of an integral combination of a vertical conveyor (2) and a high speed bulk projector (5), and a rotary bucket wheel type bulk feeder (6) arranged on one side of said bulk projector, said bulk projector (5) including a bulk receiving chute (53) having bulk inlet mouth (530) opening toward the bulk charging port (63) of said bulk feeder, said vertical conveyor (2) being arranged in a substantially vertical space defined in a tubular casing frame and including two endless conveyor belts (2a, 2b) adapted to be driven upwardly in a substantially vertical direction in a face-to-face overlapping relation closely engaging each other along the opposite side edges thereof so as to serve the purpose of conveying bulk material as held between the opposing faces of the two conveyor belts vertically upward, said two conveyor belts being guided at the bulk-receiving bottom end so as to turn around in directions opposite to each other, said tubular casing frame including a vertical frame section and a lower frame section tiltably joined thereto and being formed at the bottom end with an overhanging portion, said bulk projector (5) being carried on said overhanging portion of said tubular casing frame to serve to project bulk material rapidly under the effect of centrifugal force in an inclined upward direction to the bottom belt junction where the two endless conveyor belts come to join each other; a delivering unit carrier including a traveling frame (72 or 75) arranged in straddling relation to a bulk storing yard made on a definite lot of ground as surrounded on its opposite side by a pair of carrier supporting rails (R 1 , R 2 , or R 3 ) laid parallel to each other on top of retaining walls (91, 92) or on the surrounding ground of said bulk storing yard (Y 1 , Y 2 , or Y 3 ) and comprised of a beam structure extending transversely thereof and supported at the opposite ends on respective leg structures (724, 725 or 753) arranged to travel along the opposite sides of the bulk storing yard and a unit support frame (73 or 76) movable along said beam structure and supporting said delivering unit (71) for vertical movement and rotation about the vertical axis thereof; and intermediate transfer means provided between the bulk discharging mouth (712) at the top of said delivering unit and a stationary conveyor arranged sidewise of the bulk storing yard in parallel thereto.

Claim 4

A vertical yard delivering system comprising: a delivering unit (71) in the form of a vertical bulk-delivering unit (71) including a vertical bulk-conveying apparatus comprised of an integral combination of a vertical conveyor (2) and a high speed bulk projector (5), and a rotary bucket wheel type bulk feeder (6) arranged on one side of said bulk projector, said bulk projector (5) including a bulk receiving chute (53) having bulk inlet mouth (530) opening toward the bulk charging port (63) of said bulk feeder, said vertical conveyor (2) being arranged in a substantially vertical space defined in a tubular casing frame and including two endless conveyor belts (2a, 2b) adapted to be driven upwardly in a substantially vertical direction in a face-to-face overlapping relation closely engaging each other along the opposite side edges thereof so as to serve the purpose of conveying bulk material as held between the opposing faces of the two conveyor belts vertically upward, said two conveyor belts being guided at the bulk-receiving bottom end so as to turn around in directions opposite to each other, said tubular casing frame including a vertical frame section and a lower frame section tiltably joined thereto and being formed at the bottom end with an overhanging portion, said bulk projector (5) being carried on said overhanging portion of said tubular casing frame to serve to project bulk material rapidly under the effect of centrifugal force in an inclined upward direction to the bottom belt junction where the two endless conveyor belts come to join each other; a delivering unit carrier including a traveling frame (72 or 75) arranged in straddling relation to a bulk storing yard made on a definite lot of ground as surrounded on its opposite side by a pair of carrier supporting rails (R 1 , R 2 , or R 3 ) laid parallel to each other on top of retaining walls (91, 92) or on the surrounding ground of said bulk storing yard (Y 1 , Y 2 , or Y 3 ) and comprised of a beam structure extending transversely thereof and supported at the opposite ends on respective leg structures (724, 725 or 753) arranged to travel along the opposite sides of the bulk storing yard and a unit support frame (73 or 76) movable along said beam structure and supporting said delivering unit (71) for vertical movement and rotation about the vertical axis thereof; and intermediate transfer means provided between the bulk discharging mouth (712) at the top of said delivering unit and a stationary conveyor arranged sidewise of the bulk storing yard in parallel thereto.
