<p>A hopper has a base structure designed for being mounted to an intake of a conveying mechanism for conveying particulates. The base structure has a semi-cylindrical bottom and an upstanding box shaped structure defining a top rim. A bottom portion of a flexible hopper structure is mounted to the rim of the base structure and extends upwardly to a ring of the top portion of the flexible hopper structure. An adjusting mechanism is connected to the base structure and the top structure. The adjusting mechanism enables moving the top structure from a transport position, with the top structure being disposed in proximity to the base structure, to a loading position, with at least a substantial portion of the top structure being disposed at a predetermined distance to the base structure.</p> |
