Maintaining the required cut height minimizes losses and ensures continuous shoe contact with the surface. Thus the excessive pressure of the shoe destroys the stubble and leads to its accelerated wear, and insufficient pressure is accompanied by increased losses and provokes the galloping of the header.
An analytical solution to the problem of modeling the mechanism of the KPP-4.2 hanging is an iterative execution of the analysis procedures based on the formed hypothesis, as well as the procedures of comparison and selection of options in the procedure of parametric synthesis. It is a choice of a combination of internal parameters of the flattening device, which, while satisfying the functional limitations, simultaneously stabilize the whole mechanism.
A study and analysis of the hanging mechanism of a mower-conditioner trailed KPP-4.2 using methods of theoretical mechanics, differential and integral calculus, probability theory, mathematical modeling and computer software. A geometric model has been created for calculating and optimizing the operation of the hanging mechanism. The MVA KPP-4.2 output parameters were calculated for three different cut heights.
