THE HARDNESS REGULATOR S-SHAPED STAND OF THE CULTIVATOR ON THE BASIS OF THE BOURDON TUBE
In this paper we consider the possibility of stabilizing the depth of tillage cultivator paws on elastic racks through the use of an automatic stiffness regulator, made on the basis of a flexible tubular element. The universality of the proposed device is that due to changes in the hydraulic pressure supplied to its internal cavity, the force of the element on the rack changes. Under the action of soil resistance, the elastic support undergoes a deformation of the transverse bending in which the displacements are determined on the basis of the Mohr integral. Based on the preliminary analysis, it is concluded that at certain values of hydraulic pressure, it is possible to provide a uniform depth of treatment, compensating for the action of soil resistance forces.
