摘要

The device in order to reduce the tare weight - earth of agricultural products, in particular of beets, equipped with a machine which comprises a mobile support, moving in a given direction and on which the products and the ground, it is powered. It comprises at least one rotary element (1) of the projection, the axis of rotation (dd ′) is perpendicular to the support and driven at a rate of at least 300t / min. This projection element (1) is arranged to the - the top of the support so as to be on the path of the products and the ground when those - latter move on said support; it preferably comprises at least one rigid bar (3) mounted at a distance from the axis of rotation (dd'). For example, the projection element is present in the form (1) of a reel having n rods (3) which are mounted on the periphery of a rotary frame (2) and all have the same arrangement with respect to the axis of rotation (dd ′) of the frame.
