Abstract

A transport container of conventional parallelepiped form is disclosed, wherein the container includes a perforated drum and a worm conveyor inside of the drum for loading and discharging bulk material into and out of the container. The drum and the worm conveyor are rotated in opposite directions, and are positioned in one of the corners of the container extending from one gable of the container to the other. The drum and worm conveyor permit the container to be completely and evenly filled with a bulk material, or completely emptied, without substantial dust formation. During loading operation the corner in which the drum and worm conveyor are located is turned upwards, and during discharge operation the same corner is turned downward.

Claims

1. A transport container for transportation of bulk products, said container being substantially parallelepipedically formed and having sides, gables and longitudinal corners, tube feeder means for loading and unloading bulk products into and out of said container located in a first longitudinal corner of the container and extending between the container gables, said tube feeder means including a perforated drum and a worm conveyor located within the drum, said container and said tube feeder means cooperating so that when said first longitudinal corner of the container is positioned to be at substantially the vertically highest point of the container the tube feeder means can load said container with bulk product substantially evenly distributed in said container to substantially completely fill same, and when said first longitudinal corner is positioned to be at substantially the vertically lowest point of the container the tube feeder means can substantially evenly and substantially completely unload said container.

2. Container of claim 1, wherein said tube feeder means additionally includes drum driving means located in one gable of the container for rotating said drum, and worm conveyor driving means located in the opposite gable of the container for rotating the worm conveyor.

3. Container according to claim 2, wherein said drum is rotated in a first direction during container loading, and said worm conveyor is rotated in an opposite, second direction during container loading.

4. Container according to claim 3, wherein said drum is rotated in said second direction and said worm conveyor is rotated in said first direction during container unloading operation.

5. Container according to any one of claims 1, 2, 3 or 4, wherein connection means for feeding/discharging bulk material to/from said drum is located in a wall or gable of the container.

6. Container according to any one of claims 2, 3, or 4, wherein said driving means includes motors.

7. Container according to claim 6, wherein said motors are hydraulic motors.
