The most common technology of removing the sugar beet haulm in the world is a
continuous cut of the entire mass of the green haulm with further additional removal of the upper
parts of the sugar beet heads, which is carried out without extracting the roots from the ground.
This is the scheme according to which most top harvesting machines, manufactured in the world,
now operate. However, we have found in our studies that, due to additional cutting off the upper
parts of the root crop heads, up to 10% of the sugar-bearing mass is lost. Besides, there is an
urgent need for immediate processing of the sugar beet root crops, as losses of the sugar juice
occur, and bacteria enter inside of the root crop through the cut-off part, causing rotting.
Therefore, a more favourable operation for harvesting root crop tops is not cutting off their heads
but cleaning them from the residues of the foliage. In addition, the operation of cleaning the sugar
beet roots from the residues of the foliage is subject to rather high requirements due to the absence
of the green and dry residues on the heads of the roots, as well as the losses and damage of the
root crops themselves. The purpose of this investigation is to develop a theory of the force
interaction of the flexible cleaning blade with the sugar beet head in the process of its cleaning
when the blade is mounted on the vertical driving shaft. The methods used of the investigation
are those of modelling, higher mathematics and theoretical mechanics, as well as programming
and numerical calculations on the computer. As a result of the research, an equivalent scheme
was developed and a mathematical model was constructed describing the force interaction of the
flexible cleaning blade with the surface of the sugar beet root.
