FIELD: agriculture. ^ SUBSTANCE: group of inventions relates to the field of agriculture, namely, machines for harvesting root crops. Unit of a machine and their transportation machines for harvesting root crops contain extracting means (17, 19) for extraction of root crops, transportation means (27) for transportation of root crops, and means (23, 21) for real-time maintaining of operating depth of extracting means (17, 19) at the level of the first setting value (E), The transportation means (27) are made movable with respect to extracting means (17, 19), and the unit contains means for real-time maintaining of lifting height of the transportation means (27) at the level of the given second setting value (C) regardless of the means (23, 21) for real-time maintaining of operating depth at the level of the first setting value (E). ^ EFFECT: invention enables to change over time the operating depth of the extracting means (17, 19) and/or lifting height of the transportation means (27) without stopping the machine for harvesting root crops. ^ 18 cl, 1 dwg |
