Harvesting device for an agricultural product with sorting members comprising a rotatable portion

A harvesting device for an agricultural product having an elongated shape, comprising:

• a frame having a main extension direction;
• a plurality of harvesting elements for the agricultural product, each of the plurality of harvesting elements including an elongated harvesting prong;
• a movement system for moving each of the plurality of harvesting elements in a respective plane of movement along a closed trajectory surrounding the main extension direction, wherein the closed trajectory includes a transport path for the agricultural product between a loading point of the agricultural product from a soil by the elongated harvesting prongs and a disengagement point of the agricultural product from the elongated harvesting prongs, wherein the main extension direction is, during operation of the harvesting device, transverse to the transport path;
• a plurality of bands attached to the frame, arranged in succession along the main extension direction and spaced apart so that at least one of the plurality of harvesting elements is at least partly interposed between two successive ones of the plurality of bands;
• the transport path being divided into a first section, in which a prong portion positioned radially outside the two successive ones of the plurality of bands has a constant or increasing size, and a second section, in which the prong portion positioned radially outside the band has a decreasing size to the disengagement point;
• a plurality of sorting members, each associated with one of the plurality of bands, respectively and positioned below the one of the plurality of bands, along the second section of the transport path, wherein each of the plurality of sorting members has a central axis and is at least partly rotatable about the central axis and wherein each of the plurality of sorting members comprises a rotatable portion which:
• extends along the central axis between a face proximal to the one of the plurality of bands and a face distal from the one of the plurality of bands, and
• is configured to rotate about the central axis during operation of the harvesting device.
