At that the drum is mounted with the capability of rotation opposite to the direction of movement of the crude seeds coming along the grain board into the clearance. At that cleaner of the pile surface is made in the form of the baffle arranged under the drum, in the direct proximity of the vertical axis and is mounted with the capability of rotation towards the drum.
