A container for a beverage-preparation device includes a storage chamber for pulverulent material, a discharge opening in a chamber wall, a conveying element which extends in a direction of transport, adjoins the opening, is rotatable about a longitudinal axis and is situated in the chamber, and a dispensing duct which adjoins the opening, is situated at least partly outside the chamber, has a predetermined diameter and a longitudinal direction which runs at an angle with respect to the transport direction, the conveying element extending at least substantially as far as the dispensing duct. A flexible elongate scraping member is rotatably connected to the conveying element by its first end and extends in the longitudinal direction from the conveying element into the dispensing duct. The scraping member, which may be configured to be helical, prevents pulverulent material from sticking against the inner wall, while ensuring good conveying and metering action.

A conveyor belt scraping device comprises a support shaft and at least one scraping segment arranged on the support shaft. The scraping segment has a holding end and a scraping end which is located opposite the holding end. The conveyor belt scraping device also comprises at least one holding support which is arranged on a stationary mounting and in which the support shaft is rotatably mounted, at least one drive element of a stationary drive motor, the drive element being coupled to the support shaft so as to transfer a torque, and a controller for the drive motor. The scraping end of the scraping segment can be made to contact the conveyor belt or can be released from the conveyor belt by way of a corresponding actuation of the drive motor and a movement of the drive element.

A sprocket adapted to be used in a drive unit of a chain conveyor for underground mining applications is disclosed. The sprocket may have a cylindrical body. The cylindrical body may have a front face, an axis of rotation (A-A), and a lateral surface. The sprocket may also have a scraping member provided on the front face. The scraping member may scrape off deposits during rotation of the sprocket.

A conveying device with a revolvingly led, extensively extended conveying element, which forms a conveying section with a conveying surface, and a return section, which is arranged below the conveying section. The conveying element is deflected in each case in two head-end regions, which are spaced from one another along the conveying direction. A wiper device for wiping foreign objects led along on the conveying surface of the conveying element is arranged in the front head-end region, in which the conveying element is deflected from the conveying section into the return section. The wiper device includes a wiper unit with a receiving blade, which runs transversely to the conveying direction, as well as a wiper blade, which is mounted on the wiper unit and forms a flexible wiper lip projecting toward the conveying element beyond the receiving blade.
