Abstract
A flexible funnel element attachable to a holder funnel element to form a funnel section of a material guide chute. The funnel elements include releasable connections to able the flexible elements to be interchanged at the holder elements when worn. Due to the modular construction of the funnel sections, the guide chute has component parts of different materials such that selected components may be optimized for wear resistance and maintaining the free flow of material through the chute.
Claims15
A flexible funnel element arranged to form part of a funnel section of a material guide chute, the funnel element being mountable at a holder funnel element forming part of the funnel section and comprising:
- a flexibility and an axial length greater than that of the holder funnel element;
- a radial facing surface arranged to be positioned against a radial facing surface of the holder funnel element to allow the flexible funnel element and the holder funnel element to be interconnected axially to form the funnel section;
- and
- at least one connection element arranged to radially engage a cooperative connection element at the holder funnel element to releasably attach the flexible funnel element to the holder funnel element, the holder funnel element having a hardness that is greater than a hardness of the flexible funnel element.
A funnel section arranged to form a part of a material guide chute, the funnel section comprising:
- a flexible funnel element;
- and
- a holder funnel element releasably attached to the flexible funnel element to form an axially extending assembly, wherein the flexible funnel element has a flexibility and an axial length greater than the holder funnel element, the flexible funnel element including a radial facing surface arranged to be positioned against a radial facing surface of the holder funnel element such that the flexible and holder funnel elements are interconnected axially to form the funnel section and at least one connection element provided respectively at the flexible funnel element and the holder funnel element to cooperatively engage and connect the flexible and holder funnel elements axially, the holder funnel element having a hardness that is greater than a hardness of the flexible funnel element.
