A copier 5, pressed by a spring 7 to the root head, copies its height position and sets the kinematically connected knife 1 to the required height, which cuts off the top of the root with the top with its main blade. The cleaning knife 8 due to the fact that it is located above the lower edge of the main knife of the blade does not participate in the trimming process.

After trimming the tops from the low root following the high root, the tops of cuttings remaining in the shade are also removed, but with additional cleaning knives 8. ι

Due to the fact that the working edge of the knives is bent at a certain angle to the side opposite to the direction of rotation of the knife 1, intensive scraping of ochva cuttings occurs without damage to the root, and due to the fact that it is bent, scraping of the tops of the tops occurs without cutting with sliding ”, which allows , 5 clean root vegetables without damaging them.

Thus, due to a cleaning knife on the lower surface of the disk, the knife not only cuts the tops, IQ but also cleans the roots of the remaining stalks. This allows you to increase the completeness of the removal of residues of tops from the roots and thereby improve the quality of the obtained beet raw materials.
