TROSKNINGSFORFARANDE SAMT ANORDNING FOR DESS TILLEMPNING

摘要

The invention concerns a threshing method and the threshing equipment needed in its application which operates as part of a combine harvester working in the field. Threshing is performed by means of a roll (12) rotating about its axle shaft (11) and the flail bridge (13) composed of a cylinder (14), by guiding the material to be threshed into the space between the roll and the cylinder and by gathering the seeds separated by the flail bridge from the axially transferred vegetable material in that space. It is fundamental to the invention that during threshing the cylinder (14) with which the flail bridge (13) is composed is rotated in the opposite direction to the rotation of the roll (12). In order to clean the seeds separated during threshing a rotating drum screen (16) can be located outside the flail bridge cylinder (14). The invention is intended especially for the harvesting of sunflower seeds but it can also be applied for the harvesting of other cultivated crops, for example grain harvesting.
