A conveying device (1) for picking up a sward of crop material from the ground and feeding the crop material comprises a conveying channel (28), wherein the conveying channel (28) comprises a base (30) comprising an upstream base part (43) and a downstream base part (44). The upstream base part (43) is pivotal adjacent its upstream end (45) about a transversely extending first pivot axis (57). The downstream base part (44) is pivotal about a second transversely extending second pivot axis (76) towards the downstream end (51) thereof. The downstream end (46) of the upstream base part (43) is supported on a pair of first resilient mounting members (59) and the upstream end (50) of the downstream base part (44) is supported on a pair of second resilient support members (85) through a pair of carrier arms (78) which are pivotal about a transversely extending carrier pivot axis (74). The resilience of the first and second resilient support members (59) and (85) is such that on the force with which crop material is being urged by the feed rotor (34) against the upstream and downstream base parts (43) and (44) exceeding respective predefined values, the resilient support members (59) and (85) yield, thereby permitting downward displacement of the downstream end (46) of the upstream base part (43) and the upstream end (50) of the downstream base part (44) in order to permit crop material to pass through the conveying channel (28) without becoming jammed.La présente invention concerne un dispositif de transport (1) destiné à prélever un morceau de matériau de récolte depuis le sol et à acheminer le matériau de récolte comprenant un canal de transport (28), le canal de transport (28) comprenant une base (30) comprenant une partie de base amont (43) et une partie de base aval (44). La partie de base amont (43) pivote de manière adjacente vis-à-vis de son extrémité supérieure (45) autour d'un premier axe de pivotement s'étendant transversalement (57). La partie de base aval (44
