Loader with seal collar

A loader for filling tank-shaped containers (1) with bulk material, comprising at least:

• a loading nozzle (2) with one or more outlet openings
• at least one loading bellow (3) in one piece or several pieces connecting directly or indirectly to the loading nozzle (2)
• at least one adjustment element (4) in one piece or several pieces for adjusting the loading nozzle (2) substantially in the horizontal and/or vertical and/or transverse directions, wherein a contact area of the loading nozzle (2) that can be brought to connect directly or indirectly with the container opening takes the form substantially of a pneumatically or hydraulically inflatable seal collar (9) and the loading bellows (3) is connected directly or indirectly with at least one device (5) in one piece or several pieces, for the purpose of stretching the walls of the said loading bellows (3) at least partially and/or at least in sections, whereby the said loader includes a filter unit (12) for filtering the gaseous medium forced out of the said tank-shaped container (1) through the bulk material and includes an outgoing air recirculation system (16) for recirculating the gaseous medium forced out of the said tank-shaped container (1) through the bulk material into a silo (17) being emptied;
• wherein the device (5), which has the purpose of stretching the walls of the loading bellows (3) at least partially and/or at least in sections, includes, in addition to the at least one drive element (6), for receiving a vibration movement of the said drive element (6), one or more fixture elements (7) in, at or on at least one section of the said loading bellows (3), whereby this at least one said fixture element (7) is a fixture frame substantially adapted to the peripheral shape of the said loading bellows (3), a bracket, a substantially hole-shaped opening, a rope guide eyelet applied to a ring-shaped tube reinforcement or a combination of these.
