The drum is conical and is fitted in the apparatus in a vertical position so that it widens from the bottom towards the top, and the flails are installed on the outer surface of the drum. The sieve set is formed of at least two sieves which are at least partly conical and are nested and a threshing space is located in between the drum and the sieve set. An outer shroud is conical, and the threshing unit and the sieve set are fitted inside the shroud and in between the sieve set and the shroud there is a collecting bin for the seeds and an opening is provided for removing them.
